In the photo we see a metal gate painted black.

Choosing paint for metal products, many people are guided only by price and appearance, without thinking why on the shelves construction stores, such a variety paintwork materials. But all of them are radically different from each other, and in order not to repaint the metal every year, you need to know the main selection criteria.

In this article we will tell you the best way to paint metal gates, and we will spend a small comparative review various colors.

Paint for metal can be of any company, the main criteria for its choice are its quality characteristics

Regardless of the brand of the manufacturer, price or brand of paint for metal, they all must have a certain set of qualities. So what indicators should you pay attention to when choosing?

There are quite a few important parameters, if there is no time or desire to delve into the issue, you can entrust the choice of paint and the painting itself to the master. He will pick up the right materials taking into account all the features.

If you want to choose a job yourself - Let's figure it out:

• Adhesion to metal. Paints for different surfaces may not be suitable for other materials. Therefore, the inscription "paint on metal" must be present.
• UV resistance. Since the topic of our article is painting iron gates, then resistance to sunbeams should be the main selection criterion.
• Wear resistance.
• Water resistant. Modern paints perform not only a decorative function, but also a protective one.
• Durability.
• Ease of application. Some types of paints can only be applied under special conditions and only with the help of sophisticated equipment. We will not describe such materials, but it must be taken into account that different colors are applied in different ways.
• Decorative element. If this criterion were not important, the question is how to paint iron gate I wouldn’t get up at all: we take a gray primer and apply it. All.

Beautiful gates of bright colors are now not uncommon

Advice! Regardless of which paint you have chosen, it is advisable to paint the gate with your own hands in a supine position so that there are no streaks on the surface.

As a rule, all these data, as well as detailed instructions by application, are indicated on the can of paint, but, unfortunately, this information is not always reliable. Some manufacturers intentionally write false data in order to sell their product more expensively.

Therefore, in this situation, it is better to give preference to a famous brand. Such manufacturers value their reputation and will not publish false information. Of course, the price of such paint will be slightly higher, but you get certain guarantees.

Oil based paints

Oil paints for metal work can also be used on other surfaces due to their good adhesion.

Oil paints were once the most popular material, but the point here is not the quality of the coating, but the fact that even 20-30 years ago, these paints simply had no alternative. Today they are used much less often, although they have a number of advantages, one of which, of course, is the democratic price.

Paint PF

One of the most common types of paints on oil based. She has excellent adhesion to metal, and she easily tolerates contact with water.

Despite this, PF paint is far from ideal, and here are just a few of its shortcomings:

• Long drying, which even in summer can be calculated in several days.
• Mandatory presence of a preliminary layer of primer.
• Possible fading after 2-3 seasons.
• With poor cleaning of the surface to be painted, it may begin to peel off after a few months after application.

This is far from full list, but even it is enough to consider other options.

Paint ML

Relatively new material oil based. In fact, this is a modified and improved version of the PF, and as a result with higher quality characteristics:

• ML paint dries for a maximum of 24 hours at room temperature.
• Does not fade in the sun.
• Resistant to mechanical damage.

A significant disadvantage of this paint can be considered the need to apply primer before painting, and this is an additional cost of both time and finances.

Advice! Today on the shelves you can find ML paint, which says “rust enamel”, but experience shows that it is better to prime the surface, since the quality of the paint itself leaves much to be desired.

Specialty paints and nitro-based paints

Nitro enamels are paints based on chemical solvents, so they have a sharp, unpleasant odor. The main difference between nitro and oil paints is the speed of drying. Some enamels completely dry in just a few minutes, others may take up to an hour.

And before proceeding to the description of the types of nitro enamels, we note that painting metal gates in closed and unventilated areas is strictly prohibited. Chemical components in the composition can cause significant harm to health, so you need to work with them either on the street or in a room equipped with a powerful forced exhaust.

NC

The most low-quality and short-lived paint from our entire review. We do not recommend working with her, but in fairness we could not help but mention her.

As a rule, NC paint is used for temporary painting of any products, or by unscrupulous manufacturers of metal structures. Mine appearance the coating will lose in a year, and in two years there will be no trace of it.

hammer paint

We see an example of what hammer paint looks like on metal surfaces.

Asking the question, metal gates than to paint, many prefer this particular option. In fact, hammer enamel is an ideal value for money.

It is maximally resistant to any kind of impact, and does not lose external data throughout its entire service life, and according to manufacturers, it is at least 25 years, but of course, subject to the rules for applying paint. Hammer enamel does not require a primer coat. It dissolves rust on its own and adheres strongly to the surface.

It is impossible not to mention the decorative qualities. After application, this paint begins to spread over the surface and forms small pits, resembling marks from a blacksmith's hammer, hence the name of this paint.

A certain difficulty may arise when applying hammer paint, so before getting down to business, we recommend that you watch the video in this article, which will help you clearly understand all the intricacies of the process.

Blacksmith paint WS-Plast

We deliberately left this paint for dessert, as it has no equal not only in our review, but also in the entire market of paints and varnishes. Needless to say, the price of this paint is very high, but in fact, it is worth its money.

Such a coating is not afraid of any impact at all. Even a blow with a hammer on the surface will not leave a trace on it.

Important! For blacksmith paint, a mandatory primer of the same brand is required. If a primer from another manufacturer is used, the quality of the coating is not guaranteed.

By consistency, this paint resembles liquid rubber, and has a corresponding chemical smell. Drying time maximum two hours, even if sub-zero temperature environment.

The manufacturer guarantees the high quality of the coating for at least 50 years, but so much time has not passed since the appearance of this material, so no one knows the real service life yet.

And in conclusion

Summarizing all of the above, here is a small comparative table that will help you make the right choice.

Note that all the paints in the table are in descending order of their prices, from the most expensive blacksmith's enamel to the cheapest NC paint:

In the photo we see examples of the variety of paints and their colors.

Often, when writing an article, it is difficult to give any advice or draw conclusions, but not in this case. There is a 100% leader in our review - this is paint for metal gate WS-Plast. There is also an outsider - NC paint, but it is important to remember that the quality of the finished coating largely depends on the master. Even the highest quality paint can be applied so poorly that it will not last a year.

The need to remove a loose layer of rust and peeling paint is usually needed for forged products that have already served, especially those that are in the open. For such cleaning, the most suitable tool is selected:

• Metal brush with stiff wire
• Rough texture sandpaper
• Grinder
• If there are a lot of metal products (fence,), then it would be more rational to purchase sandblasting machine. Sanding saves time and effort.

Now you need to brush off the dust, the remnants of sand and proceed to degreasing.

Cleaning new forged products has its differences. Factory grease, grease and oil stains may remain on ferrous metal. They are washed off with a 5% solution of any SMS (synthetic detergent - washing powder) or removed with a solvent. Shiny and smooth metal is treated with sandpaper R-40 and higher, dust is removed. Galvanized surfaces are washed with a jet of water, but aluminum and its alloys do not require pre-cleaning - they just immediately degrease them.

Methods for degreasing forged elements

• Hot water-soap solution (90 ° C) - so that the soap does not curdle, the water is pre-boiled, then the grated laundry soap is dissolved
• Solution caustic soda- also very hot
• Various solvents - acetone, isopropanol, 646, butyl acetate, etc. (there must be no traces of solvent on the metal before painting)

When working with chemicals should be protected open areas body with gloves, masks, goggles and do not touch fat-free surfaces.

The traditional painting option includes several stages of coating:

• rust converter- it turns after applying the composition into a durable chemically neutral coating, enhancing the anti-corrosion effect of the primer
• Special primer composition- stops the formation of rust, isolates from moisture, gives high adhesion to the metal and subsequent coating. Usually the primer has weak decorative properties and wear resistance. Although two-in-one primer enamels are produced - corrosion protection plus an attractive appearance of the product. When choosing a primer, you should pay attention to the label: most of them are universal, but there are only for indoor or outdoor use.
• Paint for forged products(for metal) - decorative coating, which is applied over the primer layer and protects it from the aggressive effects of the environment: atmospheric precipitation, sunlight, temperature fluctuations. For enhanced protection and extending the life of paints, special varnishes are sometimes applied as an additional layer.

Modern developments in the field of paints and varnishes allow you to combine the properties of all layers. For example, rust-converting substances are added to the primer, and anti-corrosion components are added to the paint. Thus, special blacksmith's paints not only give expressiveness to forged products for many years, they have increased performance and corrosion protection.

Painting - adds sophistication to stability.

How to paint the gate if you ordered an unfinished structure from the manufacturer or decided to renew the corroded and peeling leaves damaged by corrosion? In the first case, everything is simple. It is enough to remove dust and pre-apply a layer of primer.

Photo No. 1: the procedure for painting the gate with a spray gun

We will talk in more detail about the re-staining of metal doors. From the article you will learn:

• how to clean and prime the surface;
• pick up paint;
• apply a pattern to the gate by airbrushing.

Preparatory work

As we have already said, you need to start work by cleaning the surface from contamination. Choose a method based on the state of the material and budget. Unfortunately, if the metal is rusted to holes, no measures will save it. You will have to completely replace the sashes, this is an excellent reason to buy sliding gates - comfortable, modern, practical.

Surface cleaning

Since the finish coat will lie evenly only on a clean, fat-free surface, you will need to first remove the traces:

• old paint;
• oils and rust;
• dirt and grease.

Budget cleaning method

To inexpensively remove old paint and dirt, you will need:

• conventional spray gun;
• metal brush;
• sandpaper No. 60;
• white spirit or gasoline;
• rag.

You will spend 8-12 hours manually cleaning the sashes. Advantage - in minimal cost. The procedure is as follows.

1. Wash the gate with a stiff brush. Let the metal dry.
2. Remove old peeling paint wire brush.
3. Sand the unevenness of the remaining coating with sandpaper.
4. Degrease the surface with gasoline or white spirit.

Important! It is required to clean from rust and traces of old paint not only the sash, but also all fasteners and locking elements, as well as the frame.

Mechanized cleaning of metal from rust

You can also paint iron gates after a simpler, mechanized cleaning method. You will need one of the following tools to work.

Photo #2: for mechanical cleaning old paint use metal brushes

• Screwdriver with brush head. Easily copes with the task of removing old paint and traces of corrosion. The downside of the tool is that it runs on battery power. The screwdriver is quickly discharged, you will have to wait until the next start.
• Grinder machine. Great alternative sandpaper. The cost of such a tool is small - from 2000 rubles. The equipment is mains operated.
• Bulgarian with a metal brush. Brass nozzles in the form of brushes are suitable for removing old paint. If we are talking about heavy pollution, pick up a brush with interwoven threads. Work with gloves and a mask.
• Sandblasting. most expensive and difficult option cleaning. To remove dirt and traces of the old coating, the gate is removed from the hinges. If you apply a layer of paint according to the technology on a previously cleaned surface, it will last up to 6 years.

Chemical cleaning

As a rule, separate chemical cleaning is not used. And really to do beautiful gate for a summer residence or country house, it is better to play it safe and remove a layer of old paint before exposure to the sash with a reagent. So you will achieve maximum adhesion of paint to metal.

The ideal composition for removing rust is Hammerite paint and its analogues. Before applying, degrease the surface with white spirit and wash the sashes with acetone. Checking whether the metal is well degreased is simple: attach thin paper to the sash. If the fat spot does not appear on the sheet, proceed to staining.

Rust neutralizer

Now we will describe how to use a chemical wash before finishing the product.

1. Apply the reagent to the surface cleaned with a wire brush. Use a wash with a gel-like consistency - it has the best covering ability.
2. Cover the sashes plastic wrap- the created greenhouse effect will accelerate the process of paint removal.
3. Wait half an hour and remove the old coating with a spatula. Reuse the reagent if necessary.

The choice of paint and primer for the gate

Now we will tell you which primer is better to use and what paint to paint the gate with. It is important that the finish coat meets the following requirements:

• good covering ability;
• enhanced adhesion to metal;
• the absence of components that oxidize iron;
• high moisture resistance;
• high rate of elasticity;
• strength to mechanical stress.

Several types of paints for metal on the market meet these requirements.

• Silicone enamel. Differs in high strength properties and elasticity. Moisture resistant. Adheres well to metal. All organic enamels based on silicon have anti-corrosion characteristics.
• Alkyd enamel. Elastic and resistant. Suitable for exterior finish. Supplied in a wide range of colors.
• Hammer paint. It is convenient because the coating does not need to be cleaned and primed before application. Provides excellent water and dirt repellency. It is applied from a spray gun under pressure.
• Acrylic enamel. With its help, you can beautifully paint the gate of any type - swing, sectional, retractable. Withstands large temperature fluctuations, is not afraid of moisture and chemical substances, weather resistant.

Popular paint brands

Now consider the most popular brands of coloring compositions for metal.

Primer for metal

As you remember, before applying the paint, you will need another coat of primer, which will protect the surface from corrosion and provide better adhesion. finish coat with metal. To work you can use:

• ship minium;
• silver coin;
• phosphating primer VL-02;
• minium metal;
• primer for metal GF-021.

Use a sprayer to apply primer evenly. After that, you can proceed to finishing.

Color selection

Since everyone has different tastes, the shade of the future gate depends only on the preferences of the owner of the garage. The most popular are green, burgundy, brick and blue colors. For ease of choice, we place a palette of shades.

Staining tools

It is better to paint the gate using:

• spray gun - allows you to apply the coating in an even layer, without streaks;
• roller - reduces the time of work, but leaves strips that have to be rolled several times;
• brushes - increases paint consumption, complicates the procedure.

Sequence of work

We paint the metal gates sequentially from top to bottom, observing the following recommendations:

• cover surfaces that do not need to be painted with masking tape or tape;
• overlap one layer with another to hide transitions;
• wait for the layer to dry and paint over the dotted missing areas;
• paint over the hinges, grooves and latches with a thin brush;
• apply the second coat after the first one is completely dry (recommended time is indicated on the paint package).

Important! Do not apply more paint than necessary. A thick layer reduces the strength properties of the material. The optimal number of layers is 2.

Temperature regime

What happens if you ignore advice temperature regime? In 8 cases out of 10:

• the paint will swell;
• the color will turn out dull, with transitions;
• there will be streaks and influxes.

How beautiful to paint the gate?

Beautifully paint the gate allows the method of airbrushing. To work, you need an airbrush - a device similar to a spray gun, but more functional.

Photo #8: This is what an airbrush looks like

Before drawing a picture, stock up on a sketch and paints. Where can I find a sketch? You can pick up an image on the Internet or design it yourself.

Sequence of work.

1. Transfer the contours of the future image according to the sketch. To do this, use paper templates.
2. To convey the depth of the picture, alternate light and dark shades of colors.
3. Work through small parts.
4. Cover the drawing with varnish to add shine and realism.

Examples of work performed by the airbrush method are presented below. Such drawings can be applied to retractable, swing and sectional garage doors.

Paint used in artistic forging

Since art forging products are made from steel profile, which tends to quickly rust, then it becomes necessary to apply protective coating.

Forged products have certain features, namely:

• - they are made of ordinary steel, which does not form an oxide film and therefore rusts;
• - they are used and mounted both outdoors and indoors;
• - they have a large number of connecting joints between parts;
• - they are often made from a metal bar that does not have a smooth surface.

These features impose their own requirements on the choice of paint.

1. The paint must contain anti-corrosion agents to prevent rust. If interior forging is practically not affected by atmospheric phenomena, then various visors, weathervanes, gates, fences and other exterior forging experience all the delights of the weather.

2. The paint must be sufficiently resistant to physical impact - i.e. do not peel off, wear out or scratch at the slightest touch.

3. For outdoor products, the paint must be resistant to a wide range of temperatures - not cracking at temperatures below -40 and not spreading at temperatures above +40.

4. The paint must be UV resistant and retain its color in any case.

5. The paint must be non-toxic both during drying and when dry. If for outdoor products, given parameter not too important, then for forged products at home, this is extremely important. The smell of paint in many causes an allergic reaction, dizziness and nausea. In addition, the painting of products most often takes place indoors, therefore, for the safety of workers, it must have minimal toxicity in the liquid state. A

6. The paint should have good plasticity and be easy to apply. Many joints and welds should be well painted to avoid rust.

7. The paint should evenly lay down on uneven surface.
To give originality to an artistic forging product, “patina” is often applied over the main color - a special coloring matter to give the forged products the effect of antiquity. When applying a "patina", the base paint should not change its properties and lose color.

The process of coloring artistic metal products comes down to several intermediate steps:

1. cleaning (the best is sandblasting),
2. degreasing,
3. application protective film(phosphating, galvanizing or nickel plating)
4. soil application,
5. application of the main paint composition desired color.

Now many people reduce the process of painting products to two stages - cleaning and applying paint. This has become possible thanks to new dyeing technologies and new paint formulations. Some formulations allow the paint to be applied even to a rusty surface, these include Hammerite paints based on alkyd-styrene.

As for the types of painting, they can be figuratively divided into 2 types:
- powder spraying, which requires special cameras;
- painting with liquid paints, which are applied with ordinary rollers, brushes or spray guns.

Powder coating requires the polymer to be baked in special ovens at high temperature within 148-180 degrees Celsius. And since the furnace has a limited space, the spraying of bulky and voluminous forged gratings with a polymer becomes problematic. But at the same time, a strong, even polymer layer is created on the forged product. It is good to use this coloring on large surfaces with a small number of joints and openwork elements, since otherwise the granules do not quite densely fill multi-joints, and the polymer film there will be thinner and not very strong, which can lead to rolling of the protective coating in these places when installation.

liquid paints suitable for any surface, but their consumption is much higher, especially when painting large openwork through products (for example, a fence or an “open” gate). Besides liquid paints more toxic. But at the same time, there is a guarantee that all joints and elements will be completely painted over. In addition, some liquid paints, when cured, also form a durable polymer film that is not inferior in quality to powder coating.

Conventionally, paints can be divided into the following:

1.Emulsion paints. This group includes all oil and alkyd paints.
Alkyd paints are paints based on organic solvents. The most common solvent for such paints is white spirit (purified kerosene). Alkyd paints withstand wet cleaning using traditional detergents. They also protect metal surfaces well from corrosion and wear both indoors and outdoors. If you need to get a glossy finish, then again choose these paints. The use of alkyd paints is also justified when it is necessary to transfer the full saturation of the selected color to the forged product. The colors of this group also have disadvantages. They take longer to dry than acrylics and are more toxic.
The best representatives of this family of paints is the Finnish Tikkurila paint.
Our company regularly uses a wide range of paints from this Finnish company.

2.Water-dispersed paints. Including acrylic paints.
The main advantage of such paints is low toxicity and fire safety.

WS-Plast acrylic paint was specially developed by a German company for painting metal surfaces. The resulting paint composition has excellent adhesion to many metal surfaces and solid polymers, due to which the service life of such coatings can reach 6-8 years or more. Most blacksmith companies that produce premium forged products use this brand of paint to color these products. If you need to get a matte surface, then it is better not to find acrylic paints. About WS-Plast acrylic paints they say that they emphasize the skill of a blacksmith.

3.Nitroenamels.The main advantage of such paints is the speed of drying. But the disadvantages are also very significant - high toxicity and the need for perfect preparation of the metal surface before painting, which is very problematic for forging.

On Russian market many companies have appeared offering blacksmith paint with various properties, therefore, knowing what criteria paint for artistic forging should have, choosing the right one will not be difficult.
