Old batteries lose their aesthetic appearance over time, rust appears, cracks appear on the coating, paint peels off. Agree, changing the radiator in this case is not the best idea. It is much easier, faster and more economical to repaint the battery. Moreover, to update appearance heating device is quite easy.
We will help you choose suitable composition enamels, we will explain how to prepare and how to paint a radiator correctly. We will also outline the nuances that should be taken into account when working with different types of radiators.
The proposed photo ideas will inspire you to choose an interesting solution and implement your design ideas.
There is not always a material, and in many cases, a technical opportunity to deliver new radiator. It is easier to refresh the outside of the heating device if it is still able to serve. In the event that the battery has already had to be repaired or it does not heat well, then it is better.
The painting process as such is not particularly difficult, but this does not mean that you can buy any composition and immediately begin to restore the attractiveness of the radiator.
The paint must be selected according to certain parameters, and the battery must be carefully prepared. If this is not done, then the new coating will not last long, and soon you will have to repeat the process again.
An old cast-iron battery with peeling paint looks very unaesthetic. In addition, the material of its body undergoes oxidation and rust.
When choosing a composition, it is best to focus on options specifically designed for heating appliances. But if there is no such inscription on the label, you should carefully study the instructions and find data on its heat resistance.
Coating requirements:
- Thermal resistance. The composition applied to the radiator housing must withstand temperatures up to 80-90 degrees and be flawless for the time promised by the manufacturer.
- Adhesion. It is necessary that the composition has good adhesion to the surface to be painted. Did not exfoliate during heating and alternating heating / cooling.
- Corrosion protection. The composition must contain anti-corrosion substances so that the coating in direct contact with the body does not cause its destruction.
- Color fastness. An unconditional condition, because radiators are painted for aesthetic purposes, among other reasons.
- Abrasion resistance. From direct contact with a variety of furnishings, dried things, etc. the coating should not thin.
- Safety. It is very important that the composition does not contain components harmful to health.
Heating batteries, like it or not, are very often an integral element of the interior of the premises, which means that they need a certain decoration and regular maintenance. In order for the heating radiators to look neat, to serve trouble-free for as long as possible, and the paint layer to hold securely on them, without cracking and peeling, despite high temperatures, it is necessary to use special heat-resistant paints and varnishes for these purposes.
Which paint for radiators is better to choose - this question arises for all homeowners who decide to upgrade old heating appliances or are preparing to install new ones purchased unpainted. To understand what you need to pay attention to when buying a paintwork material, you need to consider the requirements for them.
What criteria must meet the paint for heating radiators
Compositions for painting radiators and heating pipes differ somewhat in their parameters from conventional paints, therefore, it is worth familiarizing yourself with their main physical, technical and operational characteristics, to which experts recommend paying special attention.
- First of all, the paint must be safe for the residents of the apartment or house, that is, it must not emit toxic fumes during the entire period of operation. Therefore, when buying, it is necessary to study the composition of the paint and its compliance with accepted standards and norms. Imported paint from European manufacturers, whose brands are presented in a large assortment on Russian market, must comply with European standards, and domestic products must comply with the norms of the current GOST. If the package contains a link not to standards, but to some mysterious specifications ( specifications), then this can be considered an “amateur” of the manufacturer, and it is better to immediately refuse such paint - its compliance with safety standards is not guaranteed in any way.
- The heat resistance of the paint should not be lower than +80 degrees, otherwise it may crack, peel off or turn yellow. Moreover, this indicator should be considered the minimum allowable - it is better if it is even higher.
- It is desirable that the paint composition be quick-drying - this factor will significantly speed up the work, since the paint is usually applied in two layers.
- The anti-corrosion properties of the paint will protect the surface of the radiators from external aggressive influences. This is usually taken into account in the production of coating formulations. metal surfaces.
- Some paints emit a sharp bad smell- they can be chosen only for those rooms that can be thoroughly ventilated.
- Moisture resistance for radiator paint is necessary for the possibility of unhindered wet cleaning with the use of detergents.
- The thermal conductivity of the paint layer must be high enough, otherwise it will reduce heat transfer from heating devices.
Types of compounds used for painting appliances and pipes of the heating system
For painting radiators and pipes of the heating circuit, paints are produced on different bases. Each of them has its positive and negative sides, and they must also be kept in mind so that these moments do not turn out to be unexpected.
Varieties by base and component composition
So, heat-resistant paints can be oil, alkyd, water-dispersion (acrylic or silicone) and powder.
Oil paints
They are made on the basis of various organic oils, and not so long ago it was practically no alternative for painting radiators. Such paints have a high hiding power, creating a dense and durable layer on the surface of the batteries, resistant to various mechanical stresses and well withstanding high temperatures.
However, in our time they have been practically abandoned, since many other compositions have appeared that are devoid of significant drawbacks inherent in oil paints:
- These paints have a rather unpleasant specific smell, which not only accompanies the process of painting and drying surfaces, but can also appear during the operation of the batteries, with very strong heating of the radiators.
- The density of the layer formed on the radiators significantly reduces the useful heat transfer of the sections.
- There is a certain difficulty in applying the composition on such a basis - unlike other paints, it is difficult to apply an oil paint in a perfectly even layer.
- When applying too thick a layer, the paint may begin to crack and peel off during the operation of heating devices.
- Over time, the surfaces lose their luster and begin to turn yellow.
- colorful coating on oil based does not preserve the metal well enough from corrosive processes and quite often you can see rust that has appeared on the surface of the batteries.
- Oil paint is characterized by the longest period of complete drying, and when applied it is very difficult to avoid smudges.
In a word, numerous shortcomings clearly outweigh the advantages (the main of which is affordable cost). Name this paint good option for heating radiators - difficult.
Alkyd enamels for radiators
Alkyd-based heat-resistant paints consist of a dispersion of pigments and special additives mixed in pentaphthalic or glyptal varnish. They are quite popular, as they have a number of advantages that allow you to reliably protect the surface of radiators from external negative influences, as well as give them a neat and aesthetic appearance.
Almost all heat-resistant alkyd enamels perfectly withstand the highest temperatures that even theoretically can occur in the heating circuit - this performance parameter is usually indicated on the product packaging. The surface painted by them has perfect smoothness and even gloss, the paint layer does not turn yellow and does not peel off over time.

Enamel for Alpina radiators
Alkyd enamels have a fairly high wear resistance, are produced in various color scheme, which allows, if desired, to choose the right color for the overall interior of the room.
However, despite the listed advantages, such compositions also have their drawbacks:
- Alkyd-based paints, which include white spirit, have an unpleasant pungent odor. It persists not only for several days after staining, but can even appear at first if the radiators are heated too much;
- Enough long time waiting for each of the layers to dry can increase the period of painting work to several days.
Alkyd enamels are also available in the form of aerosols. However, it cannot be said that in a similar way covering batteries is not as easy as it might seem at first glance.
Acrylic heat-resistant enamels
This variety paint and varnish compositions is widely used for painting elements of heating systems, as the dried layer makes the surface perfectly smooth and even, outwardly even resembling plastic. Acrylic paints are practically odorless, both during the painting process and during the operation of the heating system.
When purchasing acrylic paint, you must first study the packaging, paying attention to the manufacturer and the purpose of the composition. Special attention- the temperature that the paint can withstand, since not all acrylic coatings are designed even for 80 ºС, not to mention higher values.
Acrylic paints dry quickly - the time for their setting and complete drying is indicated in the instructions for use, and can be from ten minutes to an hour and a half for the first stage, and five hours until one layer is completely ready. In order for the coating to turn out to be of high quality, it is necessary to protect the painted batteries from moisture on them during the entire drying period.
Acrylic solutions of paints have a consistency of medium density of sour cream, they do not spread, and practically do not leave smudges. The paint must be applied to the cleaned primed surface in two coats, otherwise desired effect will not work. A significant disadvantage of acrylic compositions can be considered their low resistance to external mechanical influences, including abrasive loading.
Silicone paints for metal
High-quality silicone compounds have the ability to maintain their characteristics even when heated to critically high temperatures, so the paint based on it will withstand any heat that can be in the heating system. Paints are made on the basis of silicone resin, which is kneaded with organic or aqueous solvents. After the applied layer dries, it acquires a semi-matt sheen.
The silicone compound can be applied to an unprepared metal surface. It is resistant to mechanical stress, to abrasion load, and therefore is very durable.
The only significant drawback of this radiator paint option is its high price, so it is not as popular among consumers as compared to other formulations.
Powder paints
This type of paint consists of a special pigment powder and special binding additives. It can be called the most durable and durable coating for heating radiators, but it will not work to apply it in an apartment.
An obstacle to self-painting with a powder composition is the technology itself, that is, the creation of the necessary conditions for this process:
- Firstly, you need special equipment with which the paint will be sprayed onto the surface of the radiator, but it is very expensive.
- Secondly, you need a source of accurately verified constant voltage for applying the composition - the powder is given a positive charge, and the surface to be coated is negative.
- Thirdly, coloring should be carried out in special chamber, where after applying the composition, a certain temperature regime is created. To ensure the process of polymerization of the applied powder dye, the surface of the radiator must be heated to a temperature of +170 to 350 degrees (the specific value depends on the characteristics of the composition).
It is clear that it is absolutely impossible to achieve such conditions at home, therefore this type of coloring is most often produced under production conditions. If you want to paint your radiators with a powder composition, you can find a car repair shop that specializes in bodywork, and which is equipped with a set of equipment for painting cars using this technology.

Matte and glossy paint
Heat-resistant paint, like any other, is also divided into glossy and matte. Which one to choose - it will directly depend on the quality of the surface of the radiators.
So, for example, for old-style cast-iron batteries (such as MS-140) with rough outer walls, it is best to use glossy paints - their gloss will slightly hide surface irregularities. In addition, the glossy layer is easier to clean from the contaminants formed on them and remains in its original clean form longer.
Matte paint, on the contrary, will emphasize the flaws in the surface of the radiator. In addition, it will not hide the porosity of the surface, which for this reason will be more susceptible to contamination. Therefore, if white matte paint is chosen for cast-iron batteries, then it will quickly acquire a gray tint. It is problematic to wash the matte surface, and it will be possible to get rid of the unpleasant gray color only with a new stain.
For perfect smooth surfaces modern heating radiators, any option is acceptable in terms of the degree of gloss of the paint.
One more nuance. Sometimes manufacturers add fine chalk to the paint to achieve a dull effect. However, what is good for walls and ceilings is absolutely unacceptable for the metal surfaces of radiators. If in component composition paint indicates this ingredient, then it is better to refuse such an acquisition, since the painted surface of the battery will turn yellow over time, and quickly enough. The best option for a matte paint would be a composition that includes titanium dioxide in its composition, since it will not change its original color throughout the entire period of operation.
A brief overview of popular compositions for painting radiators
Of course, any homeowner, when starting a repair, wants to do it once and for all, so as not to return to the problem of painting radiators in a year or two. This means that it would be advisable to purchase a high-quality specialized composition, even if its price will be slightly higher than conventional paint.
The table below presents some of the well-known brands of the most commonly used alkyd and acrylic based paints, with a brief description of them. characteristic features. Perhaps this information will help determine the choice of the optimal material.

The information presented above leads to the conclusion that there is no shortage of high-quality paint compositions for heating radiators. In the assortment of stores you can find products from well-known manufacturers, and it is best to choose it, as such materials have passed the test of time and have earned their popularity due to their impeccable quality and durability. Of course, branded products have a higher price, but it's better to pay once and forget about it. repair work for several years than to spend money, time and effort on painting appliances and heating system circuits every year.
How much paint does it take to paint a radiator?
Paint manufacturers always indicate its average consumption. It would seem that everything is simple. But this is if you paint, for example, the front surface panel radiator heating: it will not be difficult to determine the required area there. Another thing is if you have to paint sectional cast-iron "accordions".
IN technical specifications heating radiators often indicate their total area - if desired, this parameter can also be found on the Internet. But in order not to force the reader to waste time on this, a special calculator has been compiled that will help to carry out calculations very quickly and accurately.
- The calculator takes into account the parameters of the most common cast iron radiators series "MS" and "ChM" of various modifications. In addition, it is possible to simultaneously take into account the additional consumption of material, if it is also planned to paint the supply and return pipes suitable for the radiator.
- Paint costs for the calculation are taken averaged, by type - oil, alkyd PF, acrylic and silicone. Despite some differences between different brands of coatings, the approximate consumption is still at about the same level. This takes into account the condition that the staining is done in white.
- Different manufacturers do not have unity in measuring consumption - volumetric values \u200b\u200bare indicated in ml / m² (or vice versa, m² / l), or by weight (kg / m²). It is still more objective to judge by the weight equivalent (as is customary in construction planning), since the volume of any paint can be increased by adding a solvent, but its hiding power will not rise from this - it depends precisely on the mass of the material. Therefore, for a unified approach, the final value will be given exactly in kilograms - on the factory packaging of paints, in addition to volume, the net weight of the packaged paint must also be indicated.
Thanks to coloring, heating batteries become more presentable and receive additional protection from corrosion. But the paint for heating radiators must be chosen correctly so that the updated coating lasts as long as possible.
We will help you in this matter. The article lists the requirements for enamels, describes the advantages and disadvantages different colors. It also provides an overview of companies whose paints and varnishes have proven wear resistance in practice.
There should be no problems with painting old solid problems. You just need to choose the right paint for them. But with radiators made of aluminum or stainless steel, the situation is radically different.
Initially, they are painted in the factory with a powder method with heat treatment. On top of this paintwork, it is problematic to apply a new layer of paintwork materials at home with your own hands.
The vast majority of manufacturers of non-cast iron heaters consider unauthorized painting of the battery surface as a reason to void the factory warranty.
Any damage or peeling of the paint layer on a newly purchased radiator is a manufacturing defect. Such equipment must be replaced. No one has canceled the warranty period yet.
Manufacturers of aluminum and steel radiators in the instructions for their products categorically prohibit their additional coloring
After drying, enamel paints create a durable and monolithic layer on the surface, air through which is not able to pass by definition.
If oxygen is left even a small chance to seep through the paintwork, then you can immediately forget about protecting the metal from corrosion. And protective functions are often the main reason for painting radiators.
At the same time, in the passports for all heating batteries there is a categorical prohibition on painting over the air outlet of the automatic air vent. If paint is applied to it, then it will be impossible to bleed air from the heating system if necessary. This point must be monitored during painting work.
The coloring of both aluminum and stainless steel at the factories is carried out with powder coloring compositions, which, after application, are “baked” in special boxes at a high temperature. Create at home the necessary conditions impossible.
And ordinary oil and other paints do not last long on such radiators. Due to low adhesion, they will inevitably flake off aluminum and steel surfaces.
If the paint is on aluminum battery started to slide, it’s easier to buy a new radiator - a paint layer applied at home on them can last a maximum of two to three years
Reliable painting of aluminum requires special painting equipment, as well as epoxy primers and enamels. All this costs a lot of money.
In addition, the slightest non-compliance with the technology inevitably leads to peeling of the applied coating. There is another option with anodic oxidation, but this is again technologically difficult and requires certain knowledge.
If there is a successful experience in painting a car body and appropriate paintwork materials, then you can take up painting, otherwise you should not do it. It is better to purchase a new heater or simply close a peeling decorative screen.
A separate topic is convectors with private fins made of steel plates (“comb”) strung on a pair of pipes. Such batteries were often installed in 1970-80s in panel high-rise buildings. You cannot paint the lamellar ribs themselves. This will lead to a sharp decrease in heat transfer.
At the same time, getting to the pipes in the middle will also not work, even with a very narrow brush. These surfaces are best left alone.
On such radiators, there are usually dampers made of iron. Here they can and should be painted to give them an aesthetic appearance. Conventional heat-resistant paints are suitable here.
enamel requirements
The main thing in choosing a paint for a home heating radiator is its heat resistance. If the marking of the can indicates that the composition has an operating temperature below + 80 ° C, then you should not take such paintwork for painting the battery.
Conventional paints and varnishes are not originally intended for painting heated elements of the heating system. After turning on the heating, they will begin to peel off or turn yellow.
Paint for self-coloring of the heater must be at the same time:
- heat-resistant - at least + 80 ° С, and preferably + 100 ° С;
- moisture resistant and resistant to abrasion;
- non-toxic;
- with high thermal conductivity;
- quick-drying.
Some, due to inexperience with batteries, choose ordinary non-heat-resistant paint for interiors. As a result, when heat is applied, it turns yellow or changes its original shade.
This is due to the presence in its composition of chalk or polymers that are not designed for high temperatures. Therefore, both the binder and the pigment must be heat resistant.
The paint on the battery is usually applied in two layers. The faster each of them dries, the faster the radiator will be ready to work. Moreover, often the faster the paintwork material dries, the more pungent the smell of the composition.
So that the family is not forced to inhale these ambers, it is often easier to remove the heater from the pipes and paint it somewhere in the garage or on the street.
But most of these enamels presented in stores are not suitable for radiators. Choose a heat-resistant composition here should be as careful as possible.
Alkyd paint with titanium white as a pigment is, although expensive, but the most ideal material for painting. cast iron battery And steel pipes heating
Depending on the solvents and modifying additives present in the composition, this enamel is divided into many varieties. Of all, it is worth highlighting the organic and organosilicon species. The first paint has a pungent odor, and the second - increased heat resistance.
organosilicon alkyd paint based on polyorganosiloxane polymers are used for painting not only batteries, but also stoves, chimneys, boilers and fireplaces. It does not contain salts, which, when heated, begin to crystallize, thereby reducing the strength of the paint layer.
This enamel calmly tolerates temperatures up to +600°C. However, when using it, it is necessary to take care of high-quality ventilation of the room. When it dries, it releases toxic fumes, so it is best to painting work produce on the street.
Option #4: Silver
If white is not a must, then you can also use the good old silver. This is aluminum powder mixed with solvent and bituminous varnish. At the same time, you should not take ready-made paints (for example, BT-177), which by definition do not differ in heat resistance.
It is best to prepare silverfish yourself from PAP-1 powder and BT-577 varnish. When they are mixed in the right proportions, you can get a paint designed for temperatures of 300-400 ° C.
It is only necessary to observe the ratio of components prescribed in the instructions for preparing this composition. Such a coating on a heating battery will last more than one year.
Brief overview of manufacturers
On sale there are heat-resistant paints and varnishes for painting heating systems, both imported and domestic. Both of them are quite suitable for coloring the battery in a cottage or apartment.
Among the main manufacturing companies can be mentioned:
- Scandinavian TIKKURILA with the "Termal" series.
- German DUFA series "Thermo" and "Aqua-Heizkorperlack".
- Russian TEX with special "enamel for radiators".
- Polish SNIEZKA.
- Slovenian BELINKA.
- Russian LAKRA.
There are many options with different prices and composition, there are plenty to choose from. Moreover, when choosing a primer for paint, it is best to opt for products from one manufacturer. Experimenting with mixing what is cheaper is not worth it.
An overview of popular thermal paints that are used to paint radiators, metal stoves and other elements of the heating circuit is given in.
The heating radiator should not be painted with the first paint that caught your eye. For these purposes, special heat-resistant enamels should be chosen.
If we take the usual paint material, then the coating from it when the battery is heated will quickly become unusable. Also, when choosing, you need to look so that among the components there is no chalk that turns yellow when heated.
Are you looking for quality paint for heating radiators? Or there is an experience of application of heat-resistant enamels? Please leave comments on the article, ask questions and participate in the discussion of the material.
Paint for heating radiators is simply necessary, as it performs the function protective coating. It prevents corrosion and damage during operation. heating element for a long time. To extend the life of the radiator, you need to use only high-quality enamel.
As a standard, paint for radiators should be odorless, non-toxic and more or less resistant to mechanical damage and thermal shock. The chemical industry represents a huge range of products that belong to this niche, but it is important to make the right choice in accordance with all characteristics. So which paint is best?
It is wrong to think that a radiator for heating can be coated with any paint with a high quality index or a significant cost. So, in the past, oil or aluminum paint was often used for heating radiators. Considering them to be the best option for this device, the use was ubiquitous.
Painting radiators using such substances is unacceptable under these conditions, since their function does not imply protection of the metal surface during high temperatures. Thus, the paint on the radiators quickly fades, cracks and even peels off, requiring re-treatment.
Imperfect versions were replaced by paints more suitable for thermal elements. Most best options is the following types of enamel:
- Alkyd. This composition can be used at temperatures not higher than 150 degrees. When the temperature rises, the color gamut does not change in any way. The paint has an unpleasant smell, which disappears after one week after staining. The cost is quite high.
- Acrylic paint for radiators. This is an odorless paint that can withstand approximately 80 degrees. Only white paint is on sale, in which a dye is added. Affordable price and the availability of the product often put it in the first place.
- Silicone aluminum. Long-term use can be up to five years without re-coating. Range temperature regime goes up to 500 degrees. The elasticity and adaptability of the composition to thermal expansion and contraction make the enamel practically invulnerable. The cost of such a substance is quite high, while there is an unpleasant odor that is retained for a long time. Such analogues dry quickly.

- Aluminum with heat-resistant varnish. In the people, such paint is called silver. Used for maximum temperature at 200 degrees. It should be applied only to a prepared heater and it is advisable to use it in non-residential premises. The composition contains many variations of petroleum products, which makes the enamel non-environmental. Smells bad and lasts a long time. Cost is moderate, availability is wide.
The advantage of such paint coatings in comparison with standard options is obvious. Odorless paint for heating radiators cannot be completely, but there are other positive characteristics.
The above compounds are resistant to thermal effects, wear-resistant during operation and do not have a persistent unpleasant odor.
What paint is better to choose
The aesthetic appearance of the radiator will largely depend not only on the cost of the selected paint, but also on compatibility with the material of the radiator itself, as well as the features of its design. What paint to paint? For primary staining, it is better to use glossy options. Paint for painting re-type heating batteries is used exactly matte - its base will hide all the irregularities and shortcomings of the radiator.
Consider examples of staining different types radiators according to their features:
- Paint for cast iron heating radiators has many nuances when painting, which relate to irregularities and not quite aesthetic joints, seams. In most cases, even matte paint does not hide all the nuances. The only right decision would be to use colored paint that repeats the shade of the interior design of the walls. If there is a need to color the battery in bright hues, then the base of the device is pre-putty.
- Aluminum and bimetal radiators it is better to paint with powder paints, but not white. The downside is that it is almost impossible to process at home. First, you need special tools. Secondly, in order to perform high-quality staining, special skills are needed.

- Spray paints, that is, paints in spray cans, on present stage are the most popular. This feature is inherent in the fact that the method of applying the agent to the surface is the simplest. The main thing is to cover the wall with some material so that it does not get dirty. It is often necessary to apply at least two coats to level the surface. It is a quick dry option.
It is better when choosing a paint to seek help from a specialist. The seller will be able to suggest which paint is best correlated with a particular type of radiator. It is necessary to take into account the preferences that relate to interior design.
Often, with the help of several types of paints, it is possible to create a visual combination regarding tone or color. It does not make sense to single out any one section of the battery.

Preparatory work
After the choice of paint for the radiator is made in accordance with the requirements for the composition and functional features product, you can start preparatory stage. It consists of the following actions:
1. First, it is worth treating the surface of the radiator. Usually secondary painting is carried out, so it is important to accurately assess the condition of the radiator before processing. If at least five layers of paint have already been applied to the battery, then it is better to remove the excess with the help of mechanized cleaning.
2. In case of severe damage to the previously applied layers, if the paint is cracked or peeling, it must be completely removed to the very base of the metal. For this, special machines or chemical flushing agents are used. This procedure should be carried out especially well.
3. In the case when there are no more than three layers, it is enough to perform surface treatment sandpaper. It is worth choosing the fine-grained one. All streaks and drops that have formed as a result of preliminary staining are preliminarily cut off. It is necessary that the surface is smooth, without the slightest roughness.
4. After sandpaper processing, processing is carried out chemicals that degrease the surface. This can be done with acetone or a solvent. Often such work requires several degrees of processing. Only after that enamel is applied to the surface.
Heating batteries are an inconspicuous element of our house and harmoniously fit into its interior if they are new, shining with fresh paint. But if the batteries are already old, the paint on them is faded and swollen, then in this state they are striking and are unlikely to decorate the house. The problem can be solved by replacing the batteries. But this is expensive and not always justified, so there is another way out - to repaint the batteries. For this purpose, a special paint for heating radiators is used. Its purpose is to protect the surface of the batteries from corrosion, giving them the desired color, as well as a decent appearance. And if earlier pipelines were painted only in white, now they are painted in the color that best suits the design of the room. Our article will discuss how to choose a paint for heating radiators and how to properly paint them. From right choice paint depends on the final result. Here you should take into account the requirements that apply to paint for batteries and heating pipes. This: Paints specially designed for painting heating batteries are of the following types: There is also oil paint, but recently it has been little used for this purpose, this option has become obsolete. What paint for radiators is better? Each of them has its pros and cons, so the choice ultimately remains with the consumer. Paint for heating radiators must be heat-resistant, abrasion-resistant and free of harmful substances To achieve high-quality coloring batteries, you need to properly prepare their surface for painting. Preparatory work before painting take longer than the painting itself. Batteries are prepared for painting in the following order: The primer must be chosen one that has anti-corrosion properties (this is usually indicated on the bank), otherwise after a while the rust will appear again. On a well-prepared surface, the paint will lie perfectly. In order for the battery painting to turn out to be of high quality, it is necessary to carefully prepare its surface - wipe off the old paint, remove rust, wash dust and dirt In modern construction stores a wide range of paints are offered, which already contain a primer and a rust converter. They are convenient in that they are applied to heating batteries without pre-training basics. Now let's look at how to paint a radiator in order to achieve good result. This must be done with the heating turned off, otherwise in some areas the paint will dry too quickly, lie in an uneven layer, smudges will form that look ugly. Of course, there is a special paint on sale that is intended for use on hot radiators, but even it can lie unevenly if the heating is not blocked. Currently, heating batteries are painted in colors that are most suitable for overall design room interior If there is no other way out and you have to paint the heater during the heating period, then you need to at least turn off the hot water supply yourself or contact the housing office workers with this request. The temperature on the radiator in this case will drop significantly. So, if you have already decided which paint is best for painting radiators, you can proceed directly to the painting process: The radiator can also be painted with a spray gun or from a spray can. Painting a heating battery with heat-resistant paint from a spray can is convenient and fast, while the paint lays down in a thin even layer When using an airbrush, it is recommended to remove the battery so that all hard-to-reach areas can be painted. Coloring with a can filled with heat-resistant paint is carried out very quickly and efficiently. Usually, detailed instructions for painting surfaces with a spray can are given on its packaging. Basic rule: perform zigzag movements from top to bottom at a distance of about 30 cm from the surface to be painted. Before painting radiators, it is important to study the technology of this process, because its observance will ensure an attractive appearance of the heater and its reliability.Rules for choosing the right paint
