Metal is one of the strongest and most durable structural materials, but it, like an elephant from a small mouse, requires protection from ordinary rust and oxidation, which can destroy not only the head of a nail, but also a serious structure. This protection consists of isolating the metal surface from the oxidizing agent - the ambient air, for which the same metal roof has to be painted regularly, creating or restoring a layer of paint and thereby increasing its overall service life. However, this “ancient” question also has a lot of subtleties, because There are many types of metal, and even more paints have been invented to protect them, often incompatible with each other, and if, for example, you paint ferrous metal with a polyurethane or epoxy compound, you can get it completely destroyed, despite its external appearance. Read how to paint metal and you can do it right choice paint if you need protection for your hardware.

How to paint iron?

This is one of the most popular questions and the word iron refers to ferrous metals, black tin, i.e. metals without alloying, special additives that slow down rusting processes. The price of such metal is low, therefore its application is highest, and the main requirement for paint will be to protect it from rust. Alkyd and oil paints have proven themselves to be the most successful in such protection, in terms of price and quality, but it is desirable, of course, that the description of their composition include anti-corrosion additives or rust converters. The property of rust to provide itself with autonomous oxygen necessary for further oxidation allows it to continue to corrode the metal under a layer of paint, so cheaper paints require more quality training iron, or the labor-intensive preparation has to be replaced with special multi-component anti-corrosion compounds.

How to paint metal?

First of all, the metal surface is washed with soapy water and cleaned of old coatings and oil stains. All places with rust stains are cleaned with a stiff wire brush or sandpaper to a characteristic metallic shine. At a minimum, it is necessary to clean off loose rust, assuming the removal of the ingrained part chemically. We wash the cleaned surface again, dry it and prime it, protecting the metal surface and increasing adhesion and adhesion of the paint layer. Not forgetting that ferrous metal is being prepared for painting, we select a primer with anti-corrosion qualities, sometimes even sacrificing adhesion. Painting is carried out over dried primer with alkyd or oil paints rollers, brushes or spray.

How to paint steel?

Steel is not much more resistant to rust than black iron, so when painting it, oxidative processes are primarily prevented. Typically, steel products are more massive than the same roofing iron, so to remove rust and old coatings, you can use its heating, when at high temperatures all the fats burn out, and the rust lags behind along with scale. The steel surface is also cleaned, washed, degreased and primed before painting. For the greatest painting efficiency, it is advisable to use primer on alkyd based with the addition of zinc phosphate or zinc chromate compounds, and painting is carried out with the same alkyd and oil compositions or alkyd enamel already used when painting alloy steels, for example, galvanized.

How to paint over rust?

The steel surface often has deep pits from rust or is complex in shape, for example, a forged surface, where ordinary cleaning is ineffective, so we can recommend complex compositions paints that combine a rust converter, a primer, and paint, so-called rust paints. There are components of rust modifiers and inhibitors, with the difference that the former eliminate existing rust, and inhibitors prevent it, which must be taken into account when choosing a universal product. Using traditional paint involves treating a rust stain with a converter, applied to the stain and washed off after at least 3-4 hours, after which the surface is primed and painted. It is advisable to use paint based on epoxy resins, prepared by mixing the contents of two packages before use. One-component epoxy compounds are still very expensive.

How to paint copper?

Not only ferrous, but also non-ferrous metals require protection by painting, where adhesion comes first, because Their rust is somewhat different, for example, the oxides are green or dark red in color and stop it in a different way. The copper surface is cleaned of dirt and oil stains, and all methods are acceptable that allow this to be done, leaving it clean and evenly rough. Then they degrease with solvents for nitro paints, for example, 646, 649, and immediately paint with special paints, the packaging of which must indicate a copper surface. In the instructions for the paint you will also find recommendations for priming copper, because... many manufacturers do it right away ready-made composition, which does not require pre-staining. Small surfaces are easy to paint spray paints, applying them in a thin, uniform layer, qualitatively painting not only flat, but also complex relief surfaces.

How to paint aluminum?

Not unusual protective painting and aluminum. Its oxides in the form white plaque and crumbling powder, I do my best to prevent this, therefore, before painting it, also with special compositions with specific instructions- aluminum surface, it is necessary to remove these oxides. The surface is cleaned of them and immediately painted; priming can be carried out even in small areas, because the faster you do this, the less aluminum will oxidize and the better the adhesion will be. Aluminum oxidizes after sanding and, nevertheless, energetic and fast movements contribute to high-quality painting. After allowing the first layer to dry, you can see the defect, which can be immediately cleaned and primed before painting. finishing layers without haste, traditionally, gaining depth and uniformity of color.

For better quality painting, it is possible to suggest preparing aluminum by anodizing, but these are electrochemical processes, which are a completely different technology.

The first step in painting rusty metal is to remove rust from it. This process can take quite a lot of time, but without it the quality of the painting will be extremely poor. To remove rust, you can use, for example, a wire brush. You can use this tool either manually or find a special attachment.

The surface cleaned with a brush will need to be carefully smoothed with a grinding machine. If you are faced with the task of cleaning a large surface of metal, perhaps the best option will use a sandblasting machine. This device will help get rid of rust quite quickly, without spending special effort. In addition, such a machine will help you deal with rust in hard to reach places, where manual removal will not be possible.

Chemical rust removal

To remove rust, you can also use special chemicals, which simply dissolve it. Such agents primarily include strong alkalis and acids. If you decide to use this method, be extremely careful when working with chemicals.

You don’t have to remove the rust, but turn it into a durable film using chemical converters. Such converters can be purchased in the form of an emulsion or suspension. However, such products have their drawbacks, for example, they add their own tint to the paint with which the metal is coated, in addition, the metal layer becomes somewhat thicker due to the use of these products.

Degreasing

The next stage of metal preparation is to clean it from dirt and remove fat from the surface. Without these procedures, the painting will also be of poor quality. Wipe the metal surface using strong detergent. Such products are often made with citrus oils, which are very effective in cleaning rusty surfaces. After such cleaning, metal may appear rust spots. You can get rid of them with a regular solvent by soaking a piece of material in it.

Primer

The cleaned surface must be thoroughly coated with an inhibitor primer containing iron oxide or zinc chromate. Apply this product following the instructions for use. Try not to use sprayers; the primer may not fill the entire porous surface of the metal.

Painting

Apply 2 layers of paint to the metal surface; it can be either matte or glossy. To apply paint, use a brush or roller. These tools will ensure maximum contact with the surface; there will be practically no unpainted areas left.

Metal products often become covered with a rusty coating when exposed to natural conditions. It is strictly not recommended to apply paint to a surface covered with rust.

Instructions

Rust can damage individual areas of the metal, or it can cover the entire metal surface. Getting rid of this plaque is quite simple, but if this is not done, any, even the highest quality paint, applied in a thick layer, will not last long. The process of metal oxidation will continue, and rust will corrode the iron, penetrating deeper and deeper inside. Treatment metal products and structures before painting significantly extends their service life, helping to prevent oxidation.

The first stage of rust removal is using a wire brush. With its help, the metal is thoroughly cleaned of loose deposits. On large surfaces it is better to use a turbine equipped with a grinding wheel. You first need to buy a corrosion converter, this product can be found in any store building materials. The surface cleaned with a brush is treated with this composition, applying it with a brush or spray. When a corrosion converter comes into contact with rust, chemical reaction, turning rusty metal into a dark solid substance. After the cleaning process is completed, the surface is covered with a layer of soil. You can start painting only after the primer has completely dried. The paint is applied in at least two layers in order to minimize the access of moisture to the iron surface.

If objects that have been exposed to rust are very small and cannot be cleaned using mechanical devices, they are treated by washing. To do this, pour rust remover into a container and leave it in it. small parts for a while. After washing, rust residues are removed and treated with a special varnish that prevents reappearance corrosion.

Products made of iron and its alloys are highly susceptible to corrosion - spontaneous destruction under the influence of external environment. To stop this process and protect the metal from destructive effects, its surface must be painted over.

If small areas are covered with rust or the metal product itself has Not big sizes, you can use regular paints and varnishes, intended for metal coating. In this case, it is necessary in advance. To do this, use metal scrapers and brushes, chisels. This process is both time-consuming and messy, but it is absolutely necessary for the paint to adhere well and last a long time.

In the case where large areas are covered with rust and the product itself is large, it is not necessary to clean its surface of rust before painting. You need to use a special paint that is applied directly to the rust. These are paints that belong to water-dispersed primers, which contain phosphoric acid. Thanks to her, chemical composition rust is transformed and modified, and a polymer film is formed on top of it, reliably protecting the metal surface from moisture. This modification of rust and scale slows down the corrosion process, preventing the penetration of moisture, but under the film the process can develop further.

To paint rusty metal surfaces, you can also use solvent-borne two-pack compositions consisting of a base and a hardener. They contain corrosion inhibitors and targeted additives based on epoxy resins. These are, for example, primer-enamels: “Rzhavoed-universal”, “Gramirust”, “XV-0278”, or a mixture of an organic solution of vinyl chloride copolymer with vinyl acetate with the addition epoxy resin"XC-500". The disadvantage of such water-based paints is that they do not big choice colors, in addition, they have a matte surface and are characterized by relatively high porosity. In addition, such coatings can only be used at temperatures not lower than +8 ° C and at air humidity not higher than 75%. But as a preliminary priming before the subsequent application of solvent-borne paints, they can also be used in more extreme applications.

In more aggressive environments for finishing it is necessary to use those with a greater degree of protection and wider color scheme two-pack solvent-based paints, or the recently introduced one-pack solvent-borne protective and decorative coatings for rusty metal surfaces. These modern paints and varnishes have a higher degree of protection due to the presence of aluminum powder in their composition. It has high reflectivity and protects the metal surface from any type of radiation, while simultaneously reducing its temperature, making operating conditions more comfortable. The use of single-pack solvent-based protective and decorative coatings significantly reduces the cost of painting technology for rusty surfaces and reduces the period repair work.

Tip 4: Paints for rust - a simple solution to a complex problem

Cleaning large surfaces from rust is time-consuming, dirty and troublesome. I don't really want to do this kind of work. It’s good that there are many anti-rust paints and enamels; they make the process of painting an old metal surface much easier.

Why you can work faster with rust paint

If you do everything according to the rules, painting an old rusty garage can take a very long time. The complex interweaving of pipes is also not easy to clean from rust flakes. This work is long and dirty.

Regular paint does not adhere to rusty areas and will fall off very quickly if you do manage to secure it somehow. Anti-corrosion enamels for metal contain special components that penetrate the metal through the smallest pores and stop destruction.

No need to clean before applying paint. old surface to clean metal, just brush away the flakes of the old coating, which are ready to fall off on their own.

What kind of rust paints are there?

1. “Rust-eater all-rounder” - enamel primer intended for interior and exterior work. This paint is used to protect metal constructions from corrosion in unfavorable conditions that contribute to the appearance of rust. Also, “Rusteater Universal” stops the corrosion of alloys, strengthens the surface of concrete and even wood. The paint can be applied to those structures that are operated at temperatures from - 60 to + 100 ° C.
2. The Hammerite product range contains many of the most different colors by rust. Hammered hammer enamel with silicone additives restores the resistance of the metal surface to adverse atmospheric conditions. Suitable for processing ferrous and non-ferrous metals, concrete, plastic, wood. The anti-corrosion effect lasts for 8 years.
3. “Nerzhamet” - anti-corrosion paint with alkyd resins and polymer additives in its composition. It can also be applied directly to the surface without pre-treatment.
4. Anti-rust primer enamel from Novbytkhim is used for painting and protecting surfaces that are partially or completely corroded. This is a 3 in 1 product - a rust converter, decorative coating enamel and anti-corrosion primer.
5. TICIANA alkyd rust-resistant primer enamel is used indoors and outdoors. This product is well suited for strengthening rusty surfaces and creating an anti-corrosion coating. TICIANA prevents the further spread of rust under the paint layer.
6. Poli-Hammer enamel for rust, in addition to all the above-mentioned advantages of other materials, has excellent decorative qualities. After treatment with Poli-Hammer, an old rusty metal surface looks like a noble antique.

Before applying any of the above products, the metal surface must be cleaned of rust, dust and dirt, and degreased. The easiest way to do this is with special means, corroding the neigh. The most popular and effective is the Rzhavoed-Universal enamel primer. This composition will simultaneously clean and prime the metal. Among this series there are compositions that color the surface. Therefore, if you want to get a rich color, it is enough to apply a second layer of “Rusteater”.

Which rust paint is best?

A lot of positive feedback from garage owners, metal fences, boats about Hammerite rust paint. It belongs to the category of quick-drying (2 hours is enough), but for a high-quality coating it requires the application of at least two layers. This composition is recommended for use only in warm, not damp weather.

If you don't have the time or desire to do pre-cleaning metal, you can use Stainless Steel paint. It is made on the basis of alkyd resins, dries quickly and corrodes rust. But it should be taken into account that when applying this paint to an uncleaned surface, the coating layer will be raised in places. The paint will lie more evenly on prepared and primed metal, which will provide the product with an attractive finish. appearance.

If you need the most a budget option paints for rust, you can buy “Iron Lead”. This product has excellent covering ability. It can be used if you need to quickly bring a garage, fence or anything else into proper shape. “Iron lead” adheres well and, thanks to the thick layer of coating, effectively masks any flaws. But you need to know that in the fight against corrosion it is less effective than the above remedies. However, for a long period of time it will retain the appearance that was obtained after staining.

One of the most expensive and high-quality products in the fight against rust is Alpina paint (Direct auf Rost). It belongs to the category of primer enamels and was specially developed for processing. This paint is different in that it does not contain lead, which is present in many other compositions. It is almost odorless, durable, and has good covering ability. Before applying it, it is enough to clean the metal only from dirt and dust.

Metal structures can be divided into three groups according to the material used.

• The first is made of black iron.
• The second is made of galvanized iron.
• The third is made of non-ferrous metals: aluminum, its alloys, copper, etc.

The third group is extremely rare due to its high cost, so it is not worth considering.

Painting iron

Everything is clear with black iron; it must be painted. Typically, oil and alkyd paints are used in Russia for these purposes in the old fashioned way. Now in Europe, things have reached the point where water-dispersion paints are being used in such complex areas as automotive and shipbuilding. For now, we will consider the possibility of painting metal surfaces in construction. For the “lazy”, we can recommend acrylic water-dispersion primer enamels for metal. This coating will cost a little more than oil or alkyd paint, but will last much longer. In addition to the fact that acrylic coating is more durable in atmospheric conditions, it also has higher elasticity that remains unchanged from aging. In the case of metals, this is very important, because they have large linear expansions due to temperature fluctuations. Oil and alkyd paints have less elasticity than acrylic paints, and they also lose it during the aging process. As a result, at a certain point, this type of paint will simply begin to peel off from the metal surface.

Painting galvanized metal

Painting galvanized metal is a controversial operation. A layer of zinc will protect the iron well for 10-15 years. After this period, it is necessary to paint it. However, it is better to paint a new galvanized surface. This will extend its life and give it a more pleasant appearance. Galvanized iron has a more passive surface than black iron. Therefore in in this case a specialized material is required with even greater adhesion and elasticity than in the black iron version. Oil and alkyd paints are generally not suitable for this task. On a galvanized surface they will last no more than one season, and a specialized acrylic primer-enamel will delight you long years. To tell the truth, creating water-dispersion paints for metals, we ourselves did not expect how wide the possible range of their applications would be. For example, they turned out to be simply irreplaceable when painting various explosive and fire-hazardous objects.

All solvent-based paints burn well, and their vapors are also explosive. Water-dispersed materials are absolutely safe in this regard. We have successful experience in painting various metal structures and structures: hangars, garages, fences, gates, even trucks and railway cars. A small amount of rust is not a problem here. Anti-corrosion additives not only passivate its further spread, but also transform the already formed one. If the metal surface is more heavily damaged by rust, then you can use a specialized anti-corrosion acrylic primer with a rust converter, and then paint it. And all this quickly, odorless and with maximum ease of use. So, when you need to paint a metal surface, do not rush to put on a gas mask or a cotton-gauze bandage; when working with acrylic water-dispersed materials, you will not need them.

Metal roof painting

The main properties that paint must have to protect a metal roof are weather resistance and corrosion resistance. For coloring metal roofs Special industrial paints and technologies are used.

Metal roofs can be divided into three groups according to the material used:

• ferrous metal roofs;
• roofs made of galvanized metal;
• roofs made of non-ferrous metals (aluminum, copper, titanium, zinc).

The first and second groups are more accessible and widespread, although noticeably more expensive than slate. Roofs made of ferrous metal must be painted. Typically, oil and alkyd paints are used for these purposes in the old fashioned way. All this, naturally, leads to frequent repainting of the roof. In order to reliably and permanently protect a metal roof, you should use acrylic paints for roofs with anti-corrosion additives. This coating will cost a little more than oil or alkyd paint, but will last much longer. In addition to the fact that acrylic coating is more durable in atmospheric conditions, it also has an important advantage - high elasticity. In case of metal roof this is very important, since metals have large linear expansions due to temperature fluctuations.

The roof rusts not only from the outside, but also from inside(that is, from the attic side). This usually happens between the sheathing. The part of the roof that lies on the sheathing does not rust, as it is protected by wood (boards). Rust appears due to the fact that it passes through the ceilings into the attic. warm air. It is known from practice that it is often between the sheathing that there are rusted places, but sometimes they are also located under the sheathing. To protect the roof from rusting, the steel between the sheathing should be cleaned of rust with a hard brush or soft steel brush and painted with anti-corrosion galvanized paint. This will extend the life of the steel roof.

If galvanized roofing steel coatings begin to rust, then you need to, without wasting time, remove the rust and paint the surface with a special protective paint. Steel roofs Paint with large swing brushes. The technique for painting the roof is the same as for painting walls and ceilings. When painting, the paint is shaded along the slope. First of all, the roof slope is painted, and then work continues from the ridge to the slopes. When working on the roof, you should wear felt boots or ordinary shoes, but with attached felt soles that do not slip on the roofing steel and do not destroy the freshly applied paint layer. If the old coating is peeling off a lot, this means that it has insufficient adhesion to the substrate. In this case, you need to clean off the rust and flaking paint. The joint between the cleaned area and the solid paint coating Sand with sanding paper until a smooth transition is formed. Then apply roof paint to the surface.

Before use, metal products require not only decorative finishing, but also protection against the formation and spread of corrosion. For these purposes, rust paint is used. As is known, such a process develops during the reaction of iron with oxygen in the presence of water or humid air. Special formulations block the penetration of moisture onto the metal, as a result of which it does not collapse upper layer. Today the market offers a large selection of goods, and in this article we will look at which products have earned the most positive reviews and why.

Features and Specifications

Anti-rust paint for metal, due to its characteristics, has many advantages. Based on user reviews, a list of the most significant advantages was determined:

• metal and rust paint can be applied directly to existing corrosion;
• the product creates a reliable protective layer on the surface of the base that can repel dirt, dust, and moisture;
• the material has increased covering ability and good adhesion;
• the product provides long-term anti-corrosion protection;
• The products are available in various shades and are able to dry quickly.

Despite a fairly large list of advantages, the material also has disadvantages. The main disadvantage of metal and rust products for external, as well as interior works lies in the inability to process structures that are then subjected to high temperatures more than 150°C. Contact of painted objects with food or drinking water is also strictly prohibited.

Market coloring compositions offers several options for rust mixtures, varying in composition and properties:

• alkyd;
• hammer;
• epoxy;
• acrylic;
• oil

Epoxy products are not recommended for use due to increased toxicity, oil products have low resistance to temperature changes, and the alkyd version should be used on structures that are not subject to heat; in this case, an acrylic mixture is suitable. Using hammer products, it is possible to obtain a rough coating with a metallic sheen.

Best anti-rust paint for exterior metal work

Paints and varnishes perform protective functions by mechanically isolating the treated metal from the environment. The main condition is the preservation of characteristics during temperature peaks, 100% coverage of the base and resistance to mechanical loads.

Rust paint for exterior use is more likely to be universal means, since it is successfully used indoors and outdoors. The product is applied to unpainted as well as painted surfaces that consist of ferrous metal alloys. Special 3 in 1 formula includes finishing coat, primer and corrosion inhibitor, which significantly reduces the time for preparing the base.

As a result of using Hammerite, a reliable wear-resistant coating is obtained that is not subject to deformation when exposed to moisture and temperatures. The material dries relatively quickly, and subsequent application is possible after 4-6 hours. The alkyd product can be used in domestic conditions, industrial facilities, warehouses and even for the roof, if necessary.

Suitable paint for fences, pipeline systems, furniture. The base can be wood, metal, plastic, or corrosion. The material is applied using a spray gun or brush. Mechanized application is also possible. After complete drying, the coating for interior and exterior work acquires a glossy shine. Washable Hammerite at optimal environment dries in 4-6 hours. The price for a 2.5 liter container is 2500 rubles.

Prestige Primer-enamel

Economical paint for roofs against rust, as well as other metal structures, has a low consumption - 60-120 g/m2. It takes up to 40 minutes to dry, which is a big undeniable advantage.

It is possible to use xylene, R-4, R-5 as a solvent. The material has an anti-corrosion effect and a high level of resistance to various aggressive influences. Paint is used for galvanized roofs, fences, and pipeline systems. The price for a 1 liter container is 250 rubles.

The best paint for rust 3 in 1

If the can says “3 in 1”, this means that when applied, the main tasks will be performed - priming the surface, converting rust and creating a monolithic layer of enamel. Such compositions are resistant not only to water, but to mineral oils and chemical reagents.

This is a cheap hammer paint made on the basis of alkyd-styrene resin. Performs both the function of corrosion protection and decorative mixture. Used for processing clean metal structures with rust up to 0.1 mm, as well as wood surfaces.

Thanks to the packaging in 520 ml containers, the products are convenient for use in hard-to-reach places. Enamel creates a durable glossy coating that is not subject to mechanical and atmospheric influences. Acrylic mixture 520 ml costs up to 200 rubles.

VIDEO: How to paint a rusty metal surface and protect it for a long time?

How to paint rusty gates you ask. For such purposes, there are so-called primer-enamels 3 in one for interior and exterior use. They produce a triple action: rust removal, priming and painting, protection against further corrosion. If old paint If your gate begins to peel off, it is advisable to sand such areas with sandpaper. Next, the surface is painted with such a three-component enamel. From domestic producers I can recommend trademark"Special Forces". Pretty good paint.

Anti-rust paint for iron gates

Coloring garage doors and metal fences begins with the traditional question: what to do with rust? Usually, by the time it is decided to make repairs, metal structures have time to become more or less covered with rust stains.

Repair manuals published in the past, including the recent past, indicated a single sequence of actions:

• remove rust and scale,
• degrease the surface,
• and then prime and paint the metal surface.

The most labor-intensive step was removing the rust. This labor-intensive work takes up about 80% of the time devoted to repairs. Moreover, as a rule, it is not possible to completely remove rust, especially on forged products complex shape.

If unscrupulous repairmen did not try to carefully remove the rust, but covered a poorly prepared surface with ordinary paint, then soon the paint began to peel off, and the iron continued to rust intensively.

One of the insidious properties of rust is that it serves as a catalyst for further oxidation of iron. It is not for nothing that on pure metal rust does not appear evenly over the entire surface, but in the form of small spots-foci, which then grow quickly.

A great success in the fight against rust was the creation of special chemical compounds - a rust modifier and a rust inhibitor.

1. The rust modifier reacts with rust, changing chemical formula this connection. This slows down the oxidation process as the catalyst is removed.
2. A rust inhibitor is a substance that prevents the formation of rust.

Good news for everyone who periodically paints iron structures was the appearance on the market of “rust paint”. In stores that sell coatings, you can inquire about the availability of such paint. Its use Of course, loose rust will still have to be removed, along with the dirt. But dense rust can be left untouched. Anti-rust paint contains a rust modifier and inhibitor; In addition, it contains epoxy acid compounds to create a durable protective layer.

There are several types of rust paints. Some of them are supplied in the form of two packages - the contents of each package should be dissolved separately, and then combined and immediately applied to the surface. Ready mixture cannot be stored, this was the inconvenience of such paint.

Currently, there is rust paint in one package, it is in greatest demand. Rust paint price is higher than the price regular paint. Maybe. Wholesale paint and varnish products are an inappropriate purchase if the properties of the new paint are unfamiliar to you. You can first purchase the smallest package and practice using it.
