Since paint for radiators comes in a wide variety, it is not difficult to choose the optimal model in accordance with the requirements for the composition of the product and the method of application. Depending on the characteristics of the surface being processed, preference is given to samples with a glossy or matte effect. When planning to paint heating radiators, most often they opt for quick-drying, odorless compounds, although this category of paint and varnish products is not cheap.
When choosing a paint and varnish material for heating radiators, they are guided by a number of criteria:
- the safety of the paint composition, the absence of substances harmful to health and toxic fumes. The range of offers from foreign brands must comply with the requirements of European standards; for domestic products, current GOST standards are provided;
- heat resistance. Select models marked “for heating radiators”, the minimum permissible level of heat resistance of which is not lower than +80°C;
- drying speed. Priority is given to quick-drying options, the use of which significantly speeds up the finishing process;
- smell. When painting heating system elements in a well-ventilated area, it is allowed to use materials with a specific odor. In other cases, it is worth making a choice in favor of odorless paints;
- price. A wide range of prices for offers from domestic and foreign brands allows you to choose suitable product depending on preferences and financial capabilities.
Among the criteria for choosing paints for batteries, the resistance of the material to detergents is also noted.
Types and properties of paints
When choosing a finish for appliances and pipes of the heating system, it should be taken into account that the coating must meet special requirements:
- provide protection against corrosion;
- withstand prolonged exposure to high temperatures - up to 90°C or more;
- maintain color and do not fade over time.
Manufacturers offer a wide range of special paints for metal radiators, which vary in technical and decorative characteristics.
Oil paints for painting heating radiators
This category of products is made on the basis of organic oils. Coverage option applies to inexpensive solutions and until recently was popular as the only composition for finishing heating radiators.
Features of oil paints:
- good hiding power - a dense layer of high strength is created on the surface;
- resistance to high base temperatures;
Paint and varnish products for oil based have the following disadvantages:
- the specific smell of the product does not disappear for a long time;
- the oil composition is difficult to apply in an even layer;
- the finish takes a long time to dry, smudges are inevitable;
- the coating quickly loses its decorative qualities;
- the material does not have high anti-corrosion characteristics.
Despite the cheapness of the products, due to numerous shortcomings, oil paints are significantly inferior to other samples of paint and varnish products, which are presented in a large assortment.
Alkyd enamels for radiators
Alkyd-based compositions include dispersions of pigments and additives sealed in glypthal or pentaphthalic varnish. The high level of demand for products is due to a number of competitive advantages:
- alkyd coating can provide a long-term aesthetic appearance of heating equipment. The surface acquires even gloss and perfect smoothness, the paint does not peel off or turn yellow;
- the material helps to reliably protect the surface from external influences;
- the alkyd-based composition is highly wear-resistant;
- The heat resistance characteristics of alkyd enamel allow it to withstand the highest temperatures.
Alkyd paint and varnish products are presented in a variety of colors and provide an affordable price range.
There are several types of products in this category:
- Solvent-based alkyd enamel. The result of application is a beautiful glossy surface, but the composition has a pungent odor. When choosing Pesto enamel, you should be prepared for the need for tinting with blue pigment, otherwise yellowing of the coating cannot be avoided. PF-115 enamel is in particular demand.
- Paint on water based. Heat-resistant models are used to paint radiators, which eliminates darkening of the composition. If your priority is white water-based alkyd enamel, you should choose a solution with titanium pigment.
- Organosilicon enamel. The solution provides a matte texture. The temperature threshold of representatives of this group is up to 600 °C. Aerosol products are also available on the market.
Those looking for odorless radiator paint are unlikely to be satisfied with a solvent-based solution. White spirit, which is part of the product, has a pungent odor that persists for quite a long time after painting. It may also appear when the heating device is very hot.
Another minus in the collection of alkyd solutions is the duration of drying of the layers, which can lead to an increase in the period finishing works up to several days.
Hammer enamel
As a type of alkyd means for painting heating radiators, hammer enamel allows you to create a textured pattern on a metal surface, while being able to perfectly mask base defects. The presence of various pigments contributes to the implementation of such interesting solutions, such as the effect of chased texture, hammer blows and other original variations of designs.
Acrylic paints for radiators
Heat-resistant acrylic compounds are widely used for painting radiators, as they have many advantages:
- On the metal surface of heating system elements, acrylic enamel creates an even and smooth coating. When the paint dries, a polymerization process occurs, resulting in a coating that visually and tactilely resembles plastic;
- Acrylic enamel is ideal if odorless battery paint is required. The composition does not smell either during the painting process or during operation of the heating system;
- The acrylic coating dries quickly. The setting period of the paint layer varies from 10 minutes. up to 1.5 hours depending on the model. It takes about 5 hours for one layer to be completely ready;
- Acrylic paint and varnish material is applied comfortably. The solution has a medium-thick consistency and does not spread during application, which avoids smudges.
There is a huge range of acrylic paints for radiators The disadvantages of acrylic enamel include the low level of resistance of the material to mechanical loads, including susceptibility to abrasives.
When choosing acrylic paint and varnish products Special attention pay attention to the purpose of the composition and temperature range. To obtain the desired effect, the coating is applied to the prepared surface in two layers. It is also necessary to protect the painted surface from moisture until the enamel has completely dried.
Acrylic enamel VD-AK-1179
Among the popular brands of acrylic paint is VD-AK-1179. The first layer of coating dries for 2 hours, after which the second layer is applied. The duration of complete drying of the enamel is 24 hours. A high-quality primer of the surface to be painted is required.
Thermakrill paint
Alp Enamel brand products have the following features:
- contains anti-corrosion additives;
- suitable for painting radiators made of any metal, including heating devices made of low-carbon steel, stainless steel, titanium and aluminum alloys;
- has a specific smell that quickly disappears.
It takes up to 30 minutes for Thermakrill enamel to partially dry; after applying the second layer, the composition dries for about 2 days.
Odorless dispersion acrylic paint for batteries
This category of paints and varnishes is designed for use at high temperatures. The dispersion acrylic composition has virtually no odor, dries quickly, and is easily and comfortably applied to the surface in an even layer. The product has high performance and decorative characteristics, is not subject to cracking, and does not fade. The material is available on the market in glossy and semi-gloss finishes.
Master Lux Aqua 40 is one of the popular paints Among the popular models of dispersion acrylic enamel, Master Lux Aqua 40 from the Dulux brand is noted. To apply the first layer, water is added to the composition at a rate of 10:1; subsequent layers of coating are performed without dilution. To eliminate the risk of rust bleeding through the pigment, it is important to prime the surface before painting it with a water-based solution.
Silicone paints for radiators
In the production of products in this category, silicone resins are used, which are mixed with organic or aqueous solvents.
Features of silicone-based paints and varnishes:
- increased heat resistance. The material is able to withstand any temperature loads that may exist in the heating system;
- ease of use. To apply silicone compounds, no preliminary preparation of the metal surface is required;
- durability. The solution is highly resistant to mechanical stress, including abrasive loads.
The big disadvantage of silicone paints and varnishes is the high cost of the material; this is perhaps the only drawback of the model.
Nuances of use depending on the visual effect
Heat-resistant enamels for radiators are divided into glossy and matte types, the choice is made taking into account the characteristics of the surface to be painted.
Gloss paint
The glossy coating shows almost all imperfections in the surface of the base, including roughness. The solution looks good only on a flat metal plane. For example, it is unlikely that you should use a glossy finish to paint an old-style cast iron radiator.
It is worth considering that the reflective effect of gloss helps to improve the perception of space, allowing you to visually expand the boundaries of the room.
Matte enamel for radiators
Over time, it loses its original color intensity, as the porous coating becomes clogged with dust particles, which leads to the effect of color loss. If you use white matte paint when installing a cast-iron heating radiator, the surface will soon acquire a grayish tint. When choosing heat-resistant matte enamel, compositions with titanium dioxide are a priority. This composition is capable of maintaining the original color regardless of the length of service.
What color enamel to paint a cast iron battery with: practical tips
To successfully eliminate problems with the choice of material for a cast iron heating radiator, it is proposed to use the following solutions:
- give preference to colored acrylic paint in a matte finish, the tonality of which is close to the shade of the covering of the walls of the room;
- choose hammer enamel for painting the radiator, the textured pattern of which allows you to level out almost all visual defects of the base;
- use white matte paint, annually updating the coating with a new layer to maintain presentability.
Another solution to the problem is the long and painstaking process of preliminary preparation of the base before painting. To do this, you need to carefully level the surface with putty, sand it and remove dust with a rag. Then you can paint the radiator with a glossy or semi-gloss version of heat-resistant enamel.
Basic rules for painting radiators
It is advisable to plan the event before or after the heating season, since it is not recommended to paint hot radiators. So that the enamel lies on metal surface in an even layer, without smudges, has not peeled off or turned yellow, painting work is carried out at an ambient temperature ranging from +15°C to +25°C.
Painting is preceded by high-quality cleaning of the radiator from the old coating. To do this, use a grinding machine or drill with a metal brush attachment. If necessary, you can use special removers to remove old paint on metal structures. Next, the surface is treated with sandpaper, the roughness is leveled with metal putty, and primed to ensure high adhesion of the paint to the base.
To paint radiators, use a brush or a narrow roller, or perform the work using a spray gun, diluting the composition with water or solvent according to the manufacturer’s instructions.
How to paint a heating radiator? - Those who have old cast iron “accordions” worry about this question literally every 2-3 years. Sometimes people think about this when they current repairs suddenly they discover that the color of the radiator does not fit into the color concept of the room at all. Every year on the shelves of construction stores the range of paint and varnish products increases and it becomes more and more difficult to make right choice. In this article you will find all the necessary information about what paint to paint radiators over old paint, how to do it, and whether this decision is always the right one.
- It is not advisable to paint modern aluminum and bimetallic batteries. Initially, they are painted at the factory with durable powder paint, which, thanks to the peculiarities of the technology, lies perfectly evenly. If you decide that the original color of the radiator (usually white) does not suit the interior of the room, and you want to repaint it, then you are unlikely to be able to achieve the same perfectly even coating. Even if you remove the battery and paint it horizontally. In addition, an additional layer of paint will reduce heat transfer, which for regions with harsh winter- a significant minus.
- It is not advisable to paint plate radiators, especially those with a large surface area. They are installed in houses where there is a network with increased internal pressure. They have low convection but high heat transfer. As for our question, due to its design, it is difficult to properly paint a heating radiator of this type, especially with a brush. If this is really necessary, then you will have to remove it, clean it thoroughly (which is very difficult) and paint it in a horizontal position with a spray gun or car paint in the form of a spray. But even this way you may not achieve a perfect application. There may be missing areas in hard-to-reach places, because the elements of the plate radiator are located too close to each other.
- Convectors and pipes with fins (especially with frequent aluminum fins) are not painted, since painting can negatively affect their heat transfer. The design of the convector, in addition to the heat source, includes a removable casing. It can be painted to enhance it general form.
- It is recommended to paint cast iron batteries. This is not difficult to do, different paints are suitable and they do not affect the heat transfer. The choice of colors is huge.
- It is possible to paint steel panel radiators. But there is a nuance here - it will not work to evenly cover the surface of the battery with a brush. You will have to use car paint in a can, and it is advisable to paint in a horizontal position.
Important! In order to bring the battery as close as possible to the desired color and color scheme rooms, it is recommended to use decorative panels. They are sold in construction stores and online stores. They can be made of wood, metal, plywood, plastic and even glass. These screens come in different shapes, colors, and sizes. They can have figured carvings, patterns, photo printing, etc. So the choice is great, and you can choose them to suit anyone, even the most exquisite interior.
- To paint a cast iron radiator, use straight and curved soft brushes, no more than 5 cm wide.
- To paint a panel radiator, use a small-width foam roller.
- Paint in cans or spray.
- Paint bath (if the paint is not aerosol).
- A special paint remover (if you decide to get rid of old paint chemically) and a metal spatula.
- A drill with a metal brush attachment for cleaning the battery from paint residues.
- Solvent.
- Gloves, safety glasses, respirator or gauze bandage, protective clothing.
- Newspapers, oilcloth, cardboard, masking tape to protect surfaces.
- Rags.
What paints are suitable for painting a radiator?
During the renovation process, we think about how to paint the radiator without smell, without streaks and drips, so that the paint dries quickly and is beautiful. appearance The device has been preserved for a long time. At the moment this is perfect paint Not yet. However, there are several options to achieve optimal results.
The following may be suitable for painting a radiator:
- water-dispersion and water-based paints;
- alkyd enamel and auto enamel;
- acrylic paint;
- oil;
- silicone-aluminum paint;
- silverfish
Let's look at each option in more detail.
Oil paint
Regarding this type of paint, let’s immediately say that theoretically it is, of course, suitable. But in practice, it is almost never used for painting batteries:
- Its biggest disadvantage is that it takes a very long time to dry. This process can take up to a month; you must admit, it is not very convenient.
- In addition, oil paint has quite bad smell.
- It is difficult to paint the surface evenly, without drips and sagging.
Important! In view of such significant shortcomings, it is recommended to choose another option for these purposes.
Water-dispersion and water-based paints
Water-dispersion paint is made on the basis of polymers and water dispersion. Its main features:
- It is moisture resistant and can be washed.
- Diluted with water.
- Mainly available in white.
The water emulsion is made on a water basis, and it:
- Can have many colors and shades.
- Not so resistant to abrasion, it can slowly wash off upon contact with water.
- Can be diluted with solvents (eg white spirit).
Important advantages of this type of paint are:
- their environmental friendliness and safety;
- no chemical odors during application;
- ease and simplicity of painting;
- possibility of tinting;
- wide choose tools for application and affordable cost.
Important! The only negative is that before painting you must prime the surface, otherwise the water in the composition will cause rust.
Alkyd enamel and auto-enamel
Alkyd enamel is one of the best options for painting a heating radiator. It behaves well at high temperatures (withstands up to 100 degrees), with temperature changes, is resistant to abrasion and comes in many colors.
Regarding its capabilities:
- This type of paint is sold everywhere and is relatively inexpensive. This is the familiar PF-115 and its imported analogues (produced by the brands ACE, Dulux, Sigma Coatings and others).
- A significant disadvantage is the persistent chemical smell, which disappears for a long time after applying this paint to the battery.
- In addition, low-quality enamel may turn yellow over time.
Auto enamel also has a persistent unpleasant odor, so the room will then have to be ventilated for a long time. There are other application nuances if you need to paint a heating radiator:
- Applying paint from a can is quick and easy, but this, of course, requires skill so that the paint layer applies evenly.
- This application may leave unpainted areas, and it is also necessary to carefully protect all surfaces surrounding the radiator from splashes.
- Auto enamel has a glossy shine; it will highlight and highlight all surface irregularities.
Acrylic paint:
- Acrylic paint It is also water based.
- It has practically no smell and has affordable price.
- The base base is white, but if this color doesn’t suit you, you can tint it in any other shade.
- Temperature limit acrylic paint is +80 degrees - for average radiators this is quite enough.
- It dries quickly. It takes less than a day to apply 2 coats and have it all dry.
- It does not turn yellow over time, but also requires preliminary priming in order to avoid rust.
- After drying, acrylic paint forms a polymer coating that is wash-resistant.
Silicone-aluminum paint:
- It fits perfectly on any surface, forming a dense layer that contracts and expands with the metal.
- It can withstand temperatures up to 500 degrees, does not require preliminary priming, is easy to clean with any means and does not lose its visual appeal for a very long time.
Important! This paint is one of the most expensive. Another disadvantage is the pungent odor, which takes a long time to dissipate.
Serebryanka
Known since Soviet times. Its modern analogues are on the shelves of hardware stores. For example, heat-resistant paint BT-177.
How is it different:
- It consists of varnish mixed with aluminum powder.
- Silver grass is inexpensive, but also has an unpleasant odor.
Color selection:
- If you just want to update the appearance of the radiator without significant costs, then paint it white. White and silver are classics of the genre.
- If you want the radiators to be inconspicuous and fit into the decor, you can paint them to match the walls.
- In a children's room, the radiator can be made part of a cheerful interior - cover it with bright paint or even make the sections multi-colored. You can apply patterns to the batteries with a brush by hand or using a stencil. It is possible to decorate the radiator using decoupage.
You already know what paint to paint radiators with, now let’s get down to the process itself. It can be divided into two stages:
- preparation (cleaning off old paint);
- applying paint.
Cleaning
Ideally, for proper cleaning, the radiator needs to be disconnected and the remaining water drained, since getting from the back side will be difficult. We will skip how to clean the battery from dust and dirt; everyone can handle this without additional advice. But there are several ways to clean old paint.
Method No. 1
The simplest and least labor-intensive method is to use a special remover. This chemical is sold in all hardware stores. But it is suitable for processing only cast iron radiators, since cast iron is inert to this substance.
Procedure:
Method No. 2
The second cleaning method is carried out using a hair dryer or a gas burner.
Important! This method is not suitable for cast iron, as the process will take a long time and will be ineffective.
Procedure:
- The essence of the method is to use a device to heat a layer of paint to high temperatures, and then scrape it off with a spatula or a stiff brush without waiting for it to cool.
- It is advisable to carry out such work outdoors, so, of course, the battery must first be removed. If this is not possible, protect the surrounding surfaces with plywood and open the windows.
Important! This method can damage the gaskets in the radiator, so be prepared for the fact that they will have to be replaced with new ones.
Method No. 3
Another thermal method is to treat the battery using a fire. The old “old-fashioned” method is labor-intensive, but it allows you to clean the battery not only outside, but also inside.
Procedure:
- Remove the radiator, unscrew all plugs and other parts.
- Disassemble the battery into sections using a radiator wrench (the sections are connected by nipples with oppositely directed threads).
Important! If this does not work out right away, then you can do it after firing.
- Make a good fire in the yard and put a radiator in it. Keep the fire going for about an hour, longer if possible.
- After removing the battery from the fire, clean it with a wire brush; this process will be easy and quick.
- After this, tap each section with a mallet to shake out all the rust that has accumulated over the years from the internal channels.
- Now all that remains is to reassemble everything using new rubber gaskets.
Important! Gaskets can be cut from an unnecessary car inner tube.
- Wipe the radiator from dirt and degrease.
Method No. 4
You can also use mechanically:
- Place an attachment on the drill (grinder) - a metal brush or an emery wheel.
- Treat the surface of the radiator.
Important! The disadvantage of this method is that many places are difficult to reach with a tool, so the work will have to be completed manually, using a stiff brush and sandpaper.
- As in previous methods, the surface should then be cleaned of debris and degreased.
Painting
When asked whether it is possible to paint heating radiators while they are hot, experts answer in the negative, because most paints will not adhere well to a hot radiator. It is better to paint outside of the heating season. If there is no way out, then paint quickly, without putting a lot of paint on the brush and immediately blend it with a thin layer. Or turn off the supply of boiling water to the radiator and wait until it cools down, then paint.
Important! During the painting process, remember to protect your eyes, hands and respiratory system from paint splashes and toxic odors.
After cleaning and degreasing, we proceed to the most important thing - painting. The procedure will depend on the type of dye chosen.
Acrylic and water emulsion
If your choice falls on acrylic or water-based paint, the radiator should be primed with an anti-corrosion compound, otherwise rust will appear over time.
Important! There are paints on sale that already have primer added to them.
Paint from a can
If you paint the battery spray paint, then the technology is like this:
- Start with hard-to-reach areas and then move to the front.
- Move from top to bottom in a zigzag motion, without staying in one place, otherwise the layer will lie unevenly.
- It is recommended to cover the surface with two layers, so after the first has dried, proceed to the second.
Important! You can take the radiator to a service station for painting, where specialists will do it professionally.
Using a spray gun
Painting with a spray gun occurs in the same way as in the case of aerosol paint.
Important! To reach all areas, it is better to paint the battery while it is removed.
Liquid solutions
If you paint with liquid paints, then protect the surrounding surfaces with oilcloth and newspapers:
- Pour paint into a paint tray and use an angled brush to cover all interior and hard-to-reach surfaces first.
- After this, use a straight brush to begin working on the front part, moving from top to bottom.
Important! Take a little paint on the brush, the layer should be thin, otherwise drips will form.
- After the first layer has dried, cover with the second. Two layers are usually sufficient.
Important! Acrylic paint and water-based emulsion dry quickly and without much odor, so you can finish it in a few hours without any problems. But alkyd enamel will dry for more than a day and emit an unpleasant odor for a long time, so we recommend painting the radiator in the summer, when it is possible to open the windows for a long time.
That's all the wisdom regarding the choice of paint for a heating device and the process of applying the dye itself. Using useful information from the article, you can do everything correctly and with minimal losses. You can be sure that by successfully updating the old battery, the interior of the room will improve.

What kind of paint should be used for batteries?
A feature of any battery is that during operation it always heats up to a high temperature. Of course, the degree of heating depends on the temperature of the coolant and other additional factors. Regardless of whether, along with cast iron, steel or non-ferrous metal, the paint that is planned to be applied to it will also heat up. heating device.
And so that the paint for heating radiators does not “please” with the unpleasant odor released into the air harmful substances, as well as the loss of its solidity, it must:
- withstand high temperatures;
- do not contain toxic substances;
- do not emit an unpleasant odor when heated;
- be resistant to aggressive environments and abrasion.
Types of dyes for batteries
Many types of paints, or rather individual representatives of these types, meet the above requirements. After all, most paints are designed for temperatures below +80 ° C. Therefore, manufacturers produce special modifications of their products.
In general, painting batteries yourself can be done with the following types of paints:
- Acrylic enamels. They are based primarily on organic solvents. This feature causes the release of a solvent odor during the application of the acrylic mixture to the battery. However, once it dries, the smell becomes history and the room is left with a radiator with a nice glossy shine. This shine lasts for many years.
- Alkyd enamels. They are known for their excellent resistance to wear and high temperatures. The range of colors of these enamels is very large, so many people choose such paints. These paint solutions also emit an unpleasant odor as they dry. It can also be felt in cases where the heating radiator gets very hot.
- Water-dispersion paint. Many experts note that such paint for radiators is optimal. This is because it does not upset the nose with a specific smell, and the drying time is very short. True, not every water-based mixture is suitable for batteries. Only those that have the appropriate designation on the packaging are suitable. Its color can be any.
- Oil paints. They were very popular in the past. Known for emitting a solvent odor upon drying and long curing times.
It is worth adding that radiator paint may contain elements that resist corrosion and improve adhesion (they are constantly used in primers). Such mixtures have different colors and do not require primers or cleaning the radiator from corrosion.
At least that's what the manufacturers note. In practice, it is better to remove rust from the heating device and use a primer. The processes are lengthy, but the results are reliable. This is often noted in different videos.
Applying paint to a heating device
This process appears to be quite simple, but it requires proper execution. Painting radiators includes the following steps:
- Removing old paint.
- Removing corrosion.
- Treatment with degreaser.
- Applying primer.
- Do-it-yourself application of several layers of dye a certain color.
The first four points are preparatory.
Features of preparation
There are two ways to remove a layer of old paint:
- Mechanical.
- Chemical.
The first involves the use of a spatula or a round metal brush attached to electric drill. Using a spatula requires physical effort as you need to move it with your hands. Moreover, it will take quite a long time to wash off the paint. This must be taken into account when calculating the total painting time. The disadvantage of this option is that it is difficult to reach the bottom of thin cracks.
A round metal brush attached to an electric drill is a more versatile method. It is capable of treating almost the entire radiator area, including many hard-to-reach places. In this case, the work time and physical effort spent will be very small. Most people like this, including those who calculate the repair time and shoot a video of the process.
The chemical method involves the use of special solvents or fatty acids. They treat the entire area of the battery and cover the treated surface with film. Then they rest. The duration of rest is indicated on the packaging. It may be different. During this time the paint becomes soft. Of course, it does not slide off (which would be very good), but removing it with a spatula grinder or a wire brush becomes very easy.
It is worth remembering that solvents emit substances harmful to the body. Therefore, when using chemical method you need to protect your hands with construction gloves, your respiratory tract with a gauze bandage, or even better, a respirator.
The surface of the radiator, cleared of paint, is treated with sandpaper. They work especially carefully in places where there is corrosion. It needs to be completely removed. Only a pure metallic sheen should remain.
For degreasing, use white spirit or any other alkaline solution.
The radiator is primed with a solution that meets the following requirements:
- is a product of the same manufacturer that produced the paint. In this case, the primer and paint work best together;
- contains substances that can resist corrosion.
Features of paint application
Before painting, the heating radiator must be cooled. This is because most paints are designed to be applied to a cold surface. If they are applied to hot metal, they will dry quickly. And this will not allow you to apply an even layer and correct smudges, stains and stains in a timely manner. In any case, when working on hot batteries, there is very little time for applying paint. In this case, the mistake made may remain uncorrected. This is often noted in various videos.
True, there are some exceptions. So, people who ask the question whether it is possible to paint hot batteries should pay attention to paints specially designed for this purpose. They are able to dry on heated metal very slowly. However, such paints are quite expensive, and the final result of the calculation small repairs will represent a considerable amount. Therefore, before painting the heating radiator in winter, it is better to turn it off and wait for it to cool. It is best to change the color of the heating device in the summer season. Then it is convenient to ventilate the room and the radiators are cold.
If you have to paint a cast iron heater in heating season ordinary paints, then you need to apply a very thin layer of paint. Apply two such layers.
The application of a color mixture of a certain color occurs in the following sequence:
- Place oilcloth or old pieces of newspaper under the radiator.
- Applying paint to the top of the product. Then they gradually go down. Thanks to this, the problem of smudges is eliminated. First, the color mixture is applied to the internal parts of the device, and then to the external parts. The entire surface needs to be painted.
- Drying of the first layer of paint.
- Apply the second layer in the same way as the first.
The battery is coated with paint using various instruments, namely:
- Brush.
- Spray gun.
- Spray can.
If you plan to use a brush, then you should take several options. The first should have soft, straight bristles. The other has curved stubble. Thanks to the second, you can work with your own hands in those places to which access is limited.
If painting with a spray gun, it is better to remove the battery. This way, excess paint will not get on the walls. In addition, there is a great opportunity to paint the most hard to reach places. Spray painting is very quick. In this case, you need to perform zigzag movements. They move from top to bottom. The distance from the surface to be treated to the can should be 30 cm.
How to paint a heating radiator: recommendations and photos It’s worth clarifying right away that painting heating radiators is not possible in all cases. First of all, it is advisable to perform this operation for cast iron radiators, a thick and uneven layer of paint on which not only spoils the exterior of the battery, but also greatly impairs the quality of heat transfer. The second type of batteries that can and should be painted are convectors, made in the form of a bent riser pipe with fins pressed onto it.
Painting cast iron radiators If you are the owner modern models radiators with aluminum sections, then it is better to abandon the idea of painting. Of course, you can paint it, but you will have to apply many layers of paint, and you are unlikely to achieve the expected effect. The fact is that the battery is painted with a brush, and this method is by definition worse than the factory one, so it is better to leave new battery models alone and, if necessary, cover it with a decorative screen.
How to paint a heating radiator: choosing paint and tools
Brushes for painting radiators Before you begin the main stage of work, you need to prepare. First, let's prepare soft brushes that should be small size and two types - straight and curved. A straight brush is intended for painting external, easily accessible areas, and a curved one is for painting the back and internal surfaces radiator
Anza flat brush for painting heating radiators Which paint to choose
The main role in this work is played by paint for radiators, which can be of the following types:
- water-dispersed;
- alkyd;
- acrylic;
- oil
Any paint for heating radiators must be resistant to abrasion, withstand high temperatures (up to 100 degrees) and not release toxic compounds when heated. According to these parameters, the above options differ significantly from each other. For example, water-dispersion paints do not have an unpleasant odor and dry quickly, but this type of coating is less resistant to abrasion than others, meaning it will have to be renewed more often.
Special alkyd enamel VD-AK-1179 for radiators Acrylic paint contains a chemical solvent, so when used, an unpleasant odor is released, which takes a long time to ventilate from the room. The advantages of this coating are high abrasion resistance and an attractive glossy appearance.
Alkyd paint for radiators also has an unpleasant odor, but is in high consumer demand due to its high abrasion resistance and a huge range of shades. In addition, the smell from modern building materials not so harsh.
Concerning oil paint, then it is used less and less as a coating for batteries and pipes. The reason for this is the unpleasant odor, long drying time and difficulty in applying an even layer.
How to paint radiators is up to you, but it is best to use alkyd paints from well-known manufacturers. All you have to do is choose suitable color coverings.

How to paint radiators: preparatory stage
So, the materials have been selected. Now you can move on to preparatory stage. Old cast iron radiators may have chipped paint and many layers on top of them, so you need to completely clean the radiator from the old paint to the metal. This operation can be performed using a hair dryer, which melts the old paint with a stream of hot air, after which it can be removed using a spatula.
Cleaning pipes and batteries with a grinder with a special nozzle
If you don’t have a hair dryer at hand, you can use alternative option– washing solution. This solution is applied to the entire surface of the radiator, after which the heating device is covered with a film. After the washing solution has been in action for an hour, the paint can be removed using a spatula.
The main layer of paint has been removed, now we clean the battery from its remnants using fine sandpaper or a special wire attachment for a screwdriver. Then degrease the surface of the radiator using a rag soaked in a special solution, such as white spirit. The final stage is to coat the radiator with an anti-corrosion primer; it will protect the radiator from corrosion, but will also improve the adhesion of the paint to the surface.

Painting a radiator: basic rules
It’s worth clarifying right away that painting the batteries should be done with the heating turned off. This limitation is due to the fact that paint dries very quickly on a hot surface, which can lead to an uneven coating layer and the formation of smudges.
How to paint a radiator after stripping Before painting the heating radiator, place an oilcloth or rag under it, which will protect the floors from paint getting on the floor. Start painting the radiator from hard-to-reach parts with a curved brush, and front side paint at the last minute. This approach will allow you not to smear the newly applied layer of paint, and your hands will remain clean.
Painting aluminum radiators with a spray can In order for the radiator paint to lay flat, it must be applied in two thin layers. To apply the second layer, you need to wait until the first one has completely dried.

Choosing odorless paint for radiators
The choice of paint and varnish coating for a heating system is a fairly pressing and undoubtedly important issue. The paint must meet the objectives: withstand high temperatures, maintain gloss for a long time and not peel off. But this is its functional and aesthetic load. But the question of which odorless paint for radiators and how to paint them sometimes remains open. An educational excursion into the world of paints and varnishes will help you figure it out.
Which one is better to choose?
The choice of paint for the heating system of an apartment or house is closely related to the material from which the batteries are made. Each type has certain properties that are friendly to the paintwork or conflict with it. The main types of materials used for the production of radiators:
- cast iron;
- bimetal;
- steel;
- aluminum.
For painting heating radiators, the manufacturer market offers a wide range of types and a rich palette of coatings:
| № | Types of paints and varnishes | Kinds paintable radiators | Advantages | Flaws | Firm- manufacturer |
| 1 | Oil paint | Cast iron | Wide color palette | It takes a long time to dry, has a persistent odor, quickly fades, cracks, and loses its shine. | "Tikkurila" etc. |
| 2 | Serebryanka | Cast iron | Excellent high temperature resistance | Persistent odor | “Lakra”, “Gloss”, etc. |
| 3 | Silicate paint | Cast iron | Designed for high temperatures | Long lasting odor | “Nevbytkhim”, “Ceresit”, etc. |
| 4 | Powder paint | Any kind | Durability, resistance to damage and high temperatures | Coloring in professional cameras | "Triton", "Ral", etc. |
| 5 | Alkyd enamel based organic solvents | Cast iron, steel, bimetal | Wide range of applications | Characteristic odor, color varies by pigment | “Olecolor”, “Enamel”, “Tex”, etc. |
| 6 | Water-based alkyd enamel | Any kind | Barely noticeable odor, no loss of color | Titanium white is added to the high-temperature paints of this series, which are not cheap | “Tex”, “Lakra”, “Enamel”, etc. |
| 7 | Alkyd hammer enamel | Cast iron, steel, bimetal | Hides imperfections of the painted coating | There is a slight odor that disappears after drying | “Olecolor”, “Tex”, “Enamel”, etc. |
| 8 | Acrylic enamel | Cast iron, steel, bimetal | Almost no smell, dries quickly, wide range of colors, durability | It is necessary to carefully prepare the surface to be painted: sand, prime | “Lakra”, “Rainbow”, “Tex”, etc. |
| 9 | Spray paint | Any kind | Wide range of colors, ease of dyeing process | Strong smell | "Kudo", "Decorix", "Newton", etc. |
Is it possible to paint hot?
Experts have different opinions on the issue of painting radiators: some argue that they need to be painted to protect them from corrosion. Others counter that applying one or another type of enamel to radiators does not perform any protective function and is purely aesthetic in nature. Another thing is painting pipes in winter, when the radiators are hot.
Paints and varnishes suitable for heating systems and withstanding high temperatures require painting over cold radiators. If radiators are coated with enamel on a hot surface, the paint will dry out “on the fly” and the quality of painting will get out of control: sagging and unsightly spots will appear.
It would not be amiss to remind you that when applied to a hot radiator, the smell of paint will intensify, and opening windows in winter for ventilation is problematic due to the cold.
Important! Consumers most often choose the white color of the battery coating, but experts say that the dark tone of the radiator color contributes to better heat transfer.
Painting process
Before you begin the paint application stage, you need to stock up on the necessary equipment:
- radiator brush (curved, with a long handle);
- regular brush (100 mm wide);
- rubber or silicone gloves;
- respirator (if the paintwork is odorous);
- newspaper (to protect the floor from paint stains);
- sanding sheet No. 2 (if necessary, cleaning batteries from uneven surfaces);
- rag;
- primer;
- dye;
- white spirit (for unexpected contact of paint with the skin).
Sometimes, the preparatory work takes longer than the painting process itself. This is not surprising, because the radiator has a lot of hard-to-reach parts that need to be washed, and in some places peel off the peeling paint and sand it.
Important! If you want to remove the old coating completely, you can use a special remover.
- Prime the prepared surface.
- In order to avoid drips, painting begins from the top of the heating system.
- The internal parts of the batteries are also covered first.
- Layers of paint are applied evenly in a thin layer.
- As the paint and varnish material dries, the radiators are repainted.
Radiator painting steps
Technology of painting over old paint
Condition of the paint heating system may be different:
- The coating, although old and faded, has a monolithic adhesion to the base. It is enough to just lightly sand the surface with sandpaper for reliable adhesion of the next layer of paint.
- The old coating has worn out in places, peeled off, and metal is visible in places. Here, more thorough grinding of the surface will be required so that chips and irregularities are not visible under the new layer.
- The paintwork is crusty, peeling off in large areas, and rust appears in places. Such paint must be mercilessly removed with a wire brush or special removers. The prepared surface is primed before applying the first layer of paintwork.
Important! You can simply renew old paint: apply fancy pattern, pre-sanding for better adhesion.
In cans
For the convenience of consumers, paint and varnish manufacturers produce aerosol coatings for radiators. It has excellent properties:
- withstands high temperatures;
- easy and quick to apply;
- dries almost instantly;
- has a pronounced gloss;
- fits perfectly on any surface.
The only negative is the strong smell, but it will disappear in just an hour.
Balloon paint is sprayed onto the surface to be painted from a distance of 30 cm. Movements should be smooth, but fast, zigzag. Depending on the quality of the surface of the heating battery, painting in several layers may be required.
Important! When working with aerosol enamel, it is necessary to cover a large area around the radiator with newspapers, because The skill in painting with spray paint will not come right away.
Possessing necessary information about heating radiator coatings, you can enlist useful tips and learn the features of technologies for using paint and varnish products.
From time to time you need to bring radiators back to normal. This is not only due to aesthetics, but also to extend the service life. There are many types of paints and varnishes on sale. But odorless paint for heating radiators is the most successful. It has a lot of advantages. It is available from different manufacturers.
When purchasing, you need to pay attention to the composition and it is better to choose well-known brands. The material from which the radiator is made is of great importance. It is necessary to take into account what material it was covered with before the repair. Some types of paints cannot be applied without first treating the surface.
Painted heating radiator in the interior of the room
Types of paints
Radiator paints are available in in different forms. They are designed for painting various metals. Some are suitable for external use, others only for internal use. Which means are better or worse, a beginner who has decided to make repairs with his own hands for the first time cannot immediately understand.
There is a basic classification of paints. Paint for heating radiators is:
- in the form of enamel;
- alkyd;
- acrylic;
- special.
Enamel
This type is used for painting pipes very rarely. The disadvantages are as follows:
- cannot be used at high temperatures;
- They smell unpleasant, and the smell is corrosive; you have to ventilate the room for several days.
There are a number of advantages:
- the assortment is rich;
- affordable price.
It is better not to use enamels for painting batteries. They are more often used for exterior work and painting walls.
Acrylic
This type of paint for radiators is widely used. Its peculiarity is that after drying the surface resembles plastic.
The main difference is that the material is odorless. Another advantage is that it dries very quickly. After 1.5-2 hours, the surface of the pipes will be dry. But such paint must be applied to a prepared surface. First, the radiator must be primed. The surface is painted in several layers.
The advantage is that when applied, the paint does not drag behind the brush. The consistency is similar to sour cream. It does not spread. The good thing about the material is that if a beginner decides to do the work with his own hands, it will not be difficult for him.
Just a note! Acrylic paint material has the advantage that it can be applied even to hot pipe. It will not affect the quality of painting in any way. But you need to pay attention, the surface must be dry. Moisture ingress is unacceptable.
Like all materials, it has its drawbacks. This is low adhesion. After 2-3 years, the paint begins to crumble, but this material is better suited for radiators than enamel.
Alkyd
This type is acceptable for radiators. The paint is heat-resistant. After drying, an even, pleasant gloss is formed. It contains white alcohol, so it smells unpleasant. The smell is persistent and will last for several days.
It is of high quality. Long service life. It tolerates both high and low temperatures.
- takes too long to dry;
- unpleasant smell.
We must remember! If it overheats, even if the paint material is completely dry, the smell may reappear.
Special
Special
Designed for a specific type of surface. Each type has specific characteristics. Made for radiators, does not smell and dries quickly. The applied layer instantly adheres to the surface of the pipes. The downside is the high cost. But all the advantages of paint will cover this disadvantage.
Paint selection
Colorful materials are selected depending on what the radiators are made of. Various metals and alloys are used for their manufacture. Therefore, you need to pay attention to the following:
- For cast iron pipes good enamels. Before you start painting, be sure to turn off the heating. This is done because, at high temperatures, the paint material will dry quickly, but will immediately begin to wrinkle. In addition, stains form on the surface of the pipes. If for some reason it is not possible to turn off the heating, then apply the paint in a very thin layer. It is better to use thinner.
- Aluminum, steel, bimetallic radiators are produced with a treated surface. It is coated with a protective powder. This makes it very difficult to paint again. You will need to clean the surface before applying paint. grinder. You should choose alkyd enamel or acrylic.
Radiator painting
Even if the paint for radiators is chosen correctly, the material is of high quality, but if the painting is done without observing the basic technological requirements, the radiator will not look the same. high level. It is especially important to study the technological rules for those who are planning to do their own painting for the first time.
First you need to prepare the radiator for painting. To do this, do the following:
- Prepare the radiator for painting. Wash well with a soft cloth, a brush and always with detergent.
- Carry out degreasing. Using sandpaper, remove all roughness from the surface.
- Remove the old coating and treat areas exposed to corrosion with a special compound.
When the radiator is prepared, you can start painting. How to paint a radiator is described below. It is done as follows:
- turn off the heating, if this does not work, dilute the paint so that it can be applied in a thin layer;
- apply paint from top to bottom to avoid unwanted smudges;
- Be sure to paint all labor-intensive places, where you can’t get a regular brush, you need to use a special one for pipes. It has a curved shape;
- It is better to apply two or three thin layers, but before applying the next layer, you need to wait for the first one to dry well.
Sometimes spray cans and rollers are used to paint pipes. They can be used when hard-to-reach places have already been painted. For convenience, you can remove the radiator from its hinges and paint it. If possible.
Important! Even if odorless paint is used for the coating, the windows still need to be opened. All work must be done with gloves.
When choosing paint, you need to take into account the type of room. If the place is public, an office, then you can use cheap materials. When renovations are carried out in a city apartment, odorless paint is required, and this is especially important if renovation work planned in the children's room.
Many people use conventional paint materials for painting pipes, which are designed for working with floors, walls, and ceilings. This is not the best option. They are not suitable for use at high temperatures, so they spread quickly and acquire a yellowish tint on the surface.
If you have to choose between glossy and matte paint materials, then you need to take into account the fact that a shiny coating always attracts attention and all the flaws, unevenness and other shortcomings of the radiator will be visible. The matte light coating will quickly turn gray because dirt accumulates in the porous structures.

Paint coating of heating devices in the apartment will significantly improve their appearance and provide reliable protection from corrosion. However, the correct choice of paint, surface preparation and application method depend on factors such as:
- metal from which heating devices are made;
- presence and safety of factory paintwork;
- design of radiators;
- cost of paint and solvents;
- availability of manufacturer's warranty.
It should be noted that an excessively thick layer of paint can significantly reduce the heat transfer efficiency of painted batteries.
Features of the painting process
Manufacturers of heating devices consider painting them as a violation of the conditions for maintaining the warranty. Therefore, the presence of damage or peeling of factory paint during the warranty period is a manufacturing defect. In this case, instead of repairing it yourself, it is better to contact the seller to replace the defective batteries.
If the warranty period has already expired, and the surface of the radiators requires updating or restoration, then you should take into account the type of metal from which the devices are made. The fact is that aluminum, steel and bimetallic sectional batteries are painted at the factory polymer paints followed by heat treatment.
This coating is highly durable, but has very weak surface adhesion. It is almost impossible to paint such products at home without removing the factory paint, and cleaning the metal surface will require considerable effort.
Recommended recovery option high-quality coating aluminum or bimetallic products - the use of epoxy primer and expensive enamels. However, this processing method requires significant financial costs and certain painting skills.
The easiest painting is for cast iron radiators like M-140 and steel convectors. In most cases, this equipment is only primed at the manufacturer and specially prepared for subsequent painting treatment. It is recommended to apply the paint 2 times to ensure a continuous coating to protect the device from corrosion.
Requirements for paints and varnishes
When deciding which paint is best to choose for radiators, you need to determine specifications materials that should provide:
- heat resistance of the coating is not lower than 80°C and resistance to color fading;
- resistance to mechanical abrasion;
- high thermal conductivity;
- moisture resistance;
- absence of toxic substances;
- quick drying.
The paint can be glossy or matte. When determining the required gloss of the coating, it is necessary to take into account that Even the smallest irregularities and defects are visible on the glossy surface.
For cast iron surfaces and complex convector designs, it is recommended to use matte compounds, and shiny colors Well suited for bimetallic and aluminum sections.
Types of paints used
To paint batteries, one of three types of paints and varnishes is most often used. This:
- acrylic paints for heating radiators;
- oil paints;
- alkyd compositions.
In addition, at home you can find the use of hammer enamels and “silver” made of aluminum powder. In factory production conditions, polymer and epoxy mixtures are used to protect the surface, followed by heat and air treatment.
Acrylic water-based compositions
Odorless paint for heating radiators is made on a binder base of PVA glue or polyacrylates. Since polyvinyl acetate glue is soluble in water, it is not recommended to use the first group of water-based paints for repairing batteries. The coating will have poor resistance to external influences and will require replacement within the first year of operation.
Acrylic enamels are an odorless paint for batteries that forms a thin, strong and durable layer on the surface. Usually the compositions are made white, which can be modified using water-based pigments. The dried layer of paint resembles matte plastic, which is easy to clean with water and does not crack under the influence of temperature.
Oily
Coatings based on drying oil and natural oils are considered traditional and have recently been used everywhere. They form a coating that is quite resistant to negative influences and is affordable for most owners of apartments and private houses. A large number of color shades allows you to solve design issues.
Among the disadvantages of oil paints, experts note:
- coating durability up to 5 years;
- presence of strong unpleasant odors during painting;
- long duration of complete drying;
- increased layer thickness, reducing thermal conductivity;
- Possible drip formation.
When choosing oil paint, you need to pay attention to heat resistance indicators. Not all compositions of this type are designed for operation at elevated temperatures. The wrong choice of paint can lead to rapid changes color shade, formation of cracks and peeling of the surface layer.
Enamels based on alkyd resins
In terms of their performance properties, alkyd coatings are superior to oil and acrylic compositions, but only if they are specially designed for painting heating radiators. Therefore, when purchasing, you must carefully study the instructions for use of the materials and only then choose the required shade.
The best heat-resistant alkyd paints are organic and silicone based. The addition of silicon increases the possible operating temperature and for some compositions it can exceed 400°C. They can be used for painting heated surfaces such as heating boilers, chimneys, stove pipes district heating with superheated water.
The wide variety of solvents and modifiers used in the production of alkyd paints has provided the market with a large number of these polymer compositions.
When dry, these paints and varnishes release toxic substances. Therefore, when working, it is necessary to ensure the necessary ventilation of the room, and even better, paint outside.
Aluminum powder
“Serebryanka” is one of the most affordable materials. To prepare it, you need to take bitumen varnish BT-577 and add aluminum powder. At the same time, an increase in the amount of powder reduces the mechanical stability of the coating and the maximum operating temperature.
Hammer
The peculiarity of such paints is the original color shade, imitating a heat-treated metal surface and high adhesion, guaranteeing the durability of the coating. The use of these materials eliminates the need for preliminary priming and reduces purchase costs. In terms of their composition, these paints and varnishes are practically no different from the described alkyd paints.
Aerosol packages
Selling paints in aerosol cans can be considered as an alternative to traditional methods of applying paints and varnishes to heating radiators. For their preparation, light solvents are used, which ensure the creation of a thin, quick-drying, even layer. During the painting process, do not bring the can too close to the surface to avoid drips.
When determining what paint to paint radiators with, pay attention to the inscriptions and containers printed on the packaging. Conscientious manufacturers will definitely indicate that this composition is intended for painting radiators and heating pipelines, as well as compliance with the State Standard.
The best paints and varnishes are made with the addition of titanium dioxide.
The presence of crushed chalk in the composition can cause a change in color shade as a result of constant temperature heating.
Thicker paints reduce material consumption when painting, while providing a continuous, even coating. That's why mass or specific gravity composition is an important technical indicator, which you should pay attention to.
Choice depending on radiator material
Cast iron
Surface structure cast iron batteries guarantees excellent adhesion to all types of paintwork materials. Therefore, when choosing a material, you should be guided only by data on heat resistance and external indicators of the coating.
Aluminum, steel and bimetal
Factory painting of such products involves powder coating followed by heat treatment. To improve the adhesion of the surface layer, you can use epoxy primer or ensure maximum possible cleaning sections from the factory coating.
Powder coating. Famous manufacturers
Among the most common brands offering paints and varnishes for heating radiators are:
- DUFA – Germany;
- TIKKURILA – Sweden;
- Radiator enamel TEX – Russia;
- SNIEZKA – Poland;
- BELINKA – Slovenia;
- LAKRA - Russia.
When choosing paint for several heating devices, it is recommended to buy products from one manufacturer and avoid mixing different varieties. Color changes can be achieved using special dyes added to the paint.
Required amount of paint
Almost every manufacturer of paints and varnishes indicates on the packaging the estimated paint consumption when applied to a flat, prepared surface. Thus, to calculate the required amount, you just need to get the area of the surface to be painted before going to the store, and then correlate it with the information on the label. There is no universal flow rate value.
Quantity consumables will increase sharply in the absence of soil, the presence of dust and pollution. In addition, the use of a sprayer allows you to save paint and varnish compared to using a conventional paint brush.
When renovating both residential and industrial premises, the choice of paint for radiators is especially important. It should be said that painting heating radiators not only performs an aesthetic function, giving them a presentable appearance, but also reduces the harmful effects of corrosion. In addition, the existing variety of colors and shades will allow you to paint the radiator so that it blends harmoniously with the intended interior.
The wrong choice of paint and varnish material can lead to the fact that when the radiators are heated, the room will constantly be filled with a pungent and unpleasant odor. To prevent this from happening, you should choose heat-resistant compounds that do not emit unpleasant odors and do not turn yellow when heated frequently. It is better to buy paint from well-tested brands, a little more expensive, but also of higher quality. This will significantly extend the life of the radiator.
In order not to make a mistake in your choice, before starting work you should study the basic properties and types of paints and enamels for radiators. According to existing standards for residential premises, paint for radiators must be odorless, non-toxic, resistant to temperature changes and withstand light mechanical damage. Heat-resistant enamels are made from a varnish solution, colored pigments, with the addition of various fillers, depending on the required properties. The latter components, in turn, affect the purpose of the paint. For example, adding organic resin to fire-resistant enamel helps to increase the complete drying time, but makes it more elastic and has a positive effect on the quality of protection.
Such enamels are used for painting concrete stoves and metal pipes, oil refining and oil production equipment and much more. Heat-resistant enamels can be used both on concrete and building surfaces, and on metal, including wires and cables.
Most optimal options When choosing paint for radiators, you can consider the most common types of heat-resistant paints and enamels on the market. Alkyd paints , manufactured according to the latest technologies, have high strength and a uniform layer structure when applied. They can be used at temperatures no higher than 150 degrees. Alkyd paints for radiators have an unpleasant odor, which disappears within a week after painting.
Acrylic paints for batteries heating is odorless and can withstand up to 80 degrees. These paints are only available in white, so to achieve the desired color you must use a dye. The low price of these paints makes them affordable and, therefore, one of the most popular.
Silicone-aluminum paints for radiators can withstand temperatures up to 500 degrees. Their service life can reach five years without re-coating. Such paints are quite expensive.
Aluminum paints with heat-resistant varnish, popularly called “serebryanka”, contain petroleum products, so they cannot be considered environmentally friendly. They have an unpleasant odor and do not dissipate for a long time. It is advisable to use them in non-residential premises.
