How to paint metal products. How to treat metal from rust before painting

Many of us are familiar with the situation when we suddenly needed to paint a metal surface, and it turns out to be all covered with rust. And with a question "how to paint rusty pipe" faced by everyone who lives in old Soviet-built houses.

Indeed, under the influence of aggressive external environment metal surfaces often rust. Many do not pay attention to this and just paint over the rust. However, after some time, they are convinced that it was still worth preparing the metal for painting correctly. Not only does the rust-painted surface look very unaesthetic, but the paint begins to peel off from it very quickly.

How to properly prepare rusty surface to painting and this short article will tell.

Depending on the amount of rust and the degree of its penetration into the metal, you can use one or more of the following steps to prepare the painted surface for painting.

Mechanical cleaning of the surface from rust

The first thing to do, of course, is to remove big chunks rust by mechanical cleaning of the surface. Usually, a metal brush is used for this. manual cleaning or a metal attachment on a grinder or drill to speed up the process.

The stage of mechanical cleaning from rust, unlike the subsequent ones, is mandatory, although quite laborious. However, even if you finish the pre-painting process at this stage, your painted surface will already look much better and the paint will last much longer.

After cleaning the surface in this way, it is highly desirable to smooth it with grinder in order to remove and even out all the bumps and scratches on the metal. Of course, if you have a very large surface to paint, it will be faster and easier to use a sandblaster, but not everyone has access to such equipment, so we will not delve into this issue.

Chemical surface cleaning

If it is not possible to remove all rust mechanically, it makes sense to use chemicals. These are acid-based products that simply corrode and dissolve rust on the surface.

Do not forget that when working with such products, as with any acids, you should be very careful and follow safety measures.

Degreasing, priming and surface painting

After removing the main layer of rust using one of the above methods, for a good adhesion of the paint, the surface must be degreased. Any strong detergent will work for this.

Next and final stage preparing the surface for painting is coating it with a primer. This step should not be skipped if you want your surface to look smooth and evenly colored. Apply primer mechanically or by spray according to instructions.

That's it, now you can paint. Apply the paint to the surface using a brush, roller or spray gun. It is recommended to paint in two layers, so that there will definitely not be unpainted areas on the surface.

And if the metal has rusted so much that it no longer makes sense to paint it, it may be worth replacing the part with a new one and getting rid of the old one. You can do it even with a little extra money. Where to hand over scrap metal you can find on this site. They will gladly accept your metal products and pay good money for it.

Ecology of knowledge. Homestead: Sometimes in a matter of a year or two, or even less, it would seem that new metal structures can become covered with a layer of rust. For painting such surfaces, there are paints and varnishes that allow painting without removing the rusty metal layer.

One of the main conditions for high-quality painting, including anti-corrosion, is careful preparation coated surfaces. But it is not always possible to clean and prepare a metal surface covered with a layer of rust. There are special paints and varnishes that allow painting without removing the rusty metal layer.

Rusting of metals

Metal structures are exposed to rust, and these processes occur in steps, chemical reactions flow from one to another. Prerequisites and conditions for the start of the rusting process: the metal contains certain impurities (carbon and sulfur), oxygen and water are available to the surface. Carbon and sulfur, which are part of the steels as additives, act as corrosion enhancers - the layer of rust formed is destroyed, a new layer of metal is exposed and the process continues.

If there is an acidic environment and/or salts are present, the rusting processes are accelerated even more. Acidity is increased by substances contained in atmospheric water- sulfurous and carbonic acid. Water causes corrosion of unprotected metal surfaces, regardless of the state of aggregation - in the form of vapor, liquid phase or ice.

When metals rust, the rust layer that appears does not protect the surface, as in the case of passivation (creation of a protective film on metals) and cannot prevent subsequent corrosion. Rust has a loose and hygroscopic structure, instantly accumulates moisture from the air and retains it. As a consequence, if rusting has begun, then the growth rust layers accelerates oxidative processes for two reasons: the nominal thickness of the metal decreases and the duration of contact with moisture and oxygen in the air increases.

In normal cases, it makes no sense to paint metals over a layer of rust. Moisture and air are accumulated in the pores of the loose structure, which is sufficient to continue the processes of destruction of metals under the paint layer. In addition, rust cannot be compared with steel in terms of density, it is a weak and loose layer, and as a result, a stress zone is formed under the paint layer - an expansion of corroded metal. As a result, the paint layer is covered with through craquelure cracks, and the paint is quickly destroyed and flies from the surface even if the paint coating is locally damaged.

Under what conditions can metals be painted without stripping

Training metal element for painting consists of stripping, grinding, priming for two times and applying a protective paint layer for finishing. But it is not always possible to clean metal surfaces, for various reasons - tightness, inaccessibility of the element, etc. In some cases, it is possible, and much easier, to apply special coatings. But the presence of these special coatings, of course, does not mean that you can do without any preparation for painting. This is not the case, for several reasons.

Firstly, a loose rusty surface layer has accumulated moisture, air, and possibly substances that can activate corrosion even without access to oxygen and water. In this case, under a layer of any paint, oxidation reactions will continue, and it is not known how this will affect the paint layer - the operating conditions of the coatings will be too extreme.

Secondly, the surface of the element to be painted may have different characteristics quality. If the rust is formed in a uniform layer of small thickness, like a powdered powder, then the paint will be able to adhere to the base metal, penetrating through the rusty layer, and there will be adhesion.

In this case, the painted layer will be durable and rusting will either slow down very much or stop altogether. But if the rusty layer is swollen, the rust begins to peel off, then any paint, even special ones, will fall behind such a surface. Peeling of the paint layer is also guaranteed if there is an oil layer on the metal (for example, the rolled profile has not been degreased). If there are residual oil impurities on the surface, then the behavior of the paint coating is difficult to predict.

About surface preparation for painting

All metal structures require surface preparation for painting, at least to a minimum. Preparation methods depend on the condition of these surfaces:

1. If rust is manifested in the form of small spots or a uniform thin layer, then the preparation consists in degreasing and dedusting. Wipe metal surfaces with rags with abundant wetting with solvents. good effect degreasing agents in aerosol packages differ, which include corrosion inhibitors (inhibitors), which reduce the chemical activity under the paint coating to zero.
2. In cases where the surface is heavily rusted, then clean manually, using a scraper. Exfoliating rust is peeled off and then treated with metal brushes. Grinding to a metallic sheen is not necessary, a layer of rust can remain if it is dense, strong and adherent to the metal surface, and preferably uniform.

Complete drying of the metal surface for painting is a prerequisite. If possible, the products are kept under a roof in conditions close to normal - humidity up to 45% and temperature 18 - 30⁰С. In order to paint stationary structures with the highest quality in atmospheric conditions, painting is timed in warm sunny weather, at least three days before painting. It is important that the moisture evaporates from the layers of rust as much as possible, this will significantly reduce the risk of rapid damage to the paint coatings.

Priming

It is possible to apply paint without first removing rusty layers in several ways, but the main technologies are possible only in the factory. Heavy metal structures undergo a special protective treatment before being sent to the construction site. For private construction, two methods are possible:

1. Passivation of the surface with compounds containing phosphoric acid, and then coating with two-component paints. These paints are considered expensive, but there is an effect from their use. The layer that is applied two-component composition, thicker and forms a strong film. Such a film makes even minimal gas exchange impossible, oxygen and water vapor do not get under the coating. In addition, two-component paints have elasticity at high coating hardness, and swelling rust is limited, its layer is compacted and further oxidation reactions on the surface under the paint layer are slowed down to zero.
2. Application of a coat of universal primer, provided the composition is suitable for rust coating, and subsequent painting with alkyd or polyurethane enamels. This method is classified as budget. Primer and enamel will protect the structure for about two to three years, after which it is necessary to renew the coating. The enamel layers are re-degreased and cleaned, and the next layer is applied on top. Over time, the total thickness of the coating will be sufficient to ensure complete isolation of the structure from the atmospheric environment.

Paint requirements and application

• To cover an untreated surface, paintwork materials are used that have the following properties:
• The thickness of the formed weather-resistant film is not less than 150 microns
• Inhibition of corrosion under the paint layer (composition contains corrosion inhibitors)
• Modification of formed rust, partial passivation

Different colorful compositions give various thicknesses coatings, and on the final resistance to external influences affects the quality and degree of chemical purity of the base. Weather-resistant paints are based on organic solvent bases and contain various additives and additives. These supplements can give different effects. Ideally - protective covering acts in such a way that the rust is deactivated simultaneously with the zero yield of all introduced substances. The reactants must react, and all the resulting substances should ideally be neutral compounds.

But such an ideal result is impossible in real life, since rust is a little different everywhere - both in chemical composition and in physical properties, depending on the operating conditions of the painted structure, steel grade and environmental conditions. Manufacturers develop the optimal proportion of additives and additives special paints, and the exact recipes are a secret. The complex effect gives the use of substances:

• Passivating compounds and substances that modify the upper layers of rust
• Substances that increase adhesion not only in the contact zone of the rust layer and the paint coating, but also throughout the entire volume of the layer damaged by rust, to a depth
• Binding of oxygen penetrating under the paint layer by adding active substances
• Penetrating solvents and primer, providing deep penetration paint composition into the porous structure of the rust-damaged layer

The results of staining metal structures directly depend on the quality of the applied paintwork materials. It is impossible to provide protection for many years using budget pentaphthal enamel.

To protect weathered metal from corrosion, a special weather-resistant paint should be used. This data is available in the labeling of the compositions: the alphabetic and numeric codes contain all the information. For example, the number one after the hyphen indicates that this composition is weather-resistant, five - respectively, special.

Alkyd and polyurethane enamels give a good protection effect. The application of special enamels is regulated by the manufacturer - in terms of the admissibility of painting with rollers, brushes or sprayers. PWM packages contain relevant information in the form of pictograms, and you can decide on the choice of a specific composition for processing elements of various sizes and shapes.publishedIf you have any questions on this topic, ask them to specialists and readers of our project.

It is almost impossible to completely prevent the formation of metal corrosion: sooner or later the metal will begin to rust. At the same time, there are ways to significantly extend the service life of the material, if you follow the rules for operating a metal product and use special means slowing down corrosion processes. If rust has already appeared, it must be removed (chemically or by mechanical means) to prevent the development of corrosion processes.

Preventive actions

To prevent the harmful effects of corrosion, it is recommended to use special chemical protection agents. These agents include inhibitors, which are substances that slow down or completely stop a particular chemical process. As a result of the action of the inhibitor, a thin coating appears on the surface of the material in the form of a protective film. It is this film that protects the metal from rusting.

One of the most popular inhibitors today is "Rust stop". The drug has a penetrating effect, as a result of which moisture is removed from the material, and a polymolecular layer is created on the surface. The product is non-toxic and easy to use.

Mechanical removal

For a mechanical one, you will need a metal brush or an abrasive coarse-grained sandpaper. Using the skin, you can clean the material in a “dry” way or “wet” (wetting the skin with kerosene or white spirit).

Other mechanical cleaning options include the use of the following hardware:

• orbital sander with abrasive wheels;
• sandblasting machine;
• nozzles for an electric drill;
• Bulgarians.

Use of hand tools (brushes or sandpaper) is justified on small surfaces. The advantage of working the surface by hand is the possibility of a more thorough pass in small or hard-to-reach areas.

Nozzle for electric drill, Grinder or a grinder can speed up surface cleaning at times. However, such methods are not very accurate: too much large layer metal.

Sandblasting equipment - best way rust removal.

The removal of corrosive products occurs due to the processing of metal with a powerful jet of sand. In this case, the undamaged metal completely retains its structure.

The disadvantage of the technique is the high cost of new equipment.

Chemical methods

Chemical methods involve the use of the following groups of drugs:

• rust converters;
• acids (primarily orthophosphoric);
• folk funds.

This substance belongs to the classic solvents and is part of many rust control products.

The method of using phosphoric acid is described below:

1. The substance is applied thin layer in place affected by corrosion.
2. Then you need to wait for 30 minutes until the reaction is completed.
3. The procedure is completed by wiping the dry treated surface.

Orthophosphoric acid removes traces of rust, and also promotes the formation of a phosphate water-repellent film. This film slows down the process of metal oxidation, preventing further development corrosive process.

A 30% acid solution is used to remove rust. The advantage of phosphoric acid over other acids (for example, sulfuric acid) is that it is more gentle on the metal.

Rust converters

The principle of operation of rust converters is to convert corrosive products into a harmless or protective layer, which can then be treated with paint or varnish.

The following are the most well-known rust converters on the market:

1. VSN-1. After applying this acid neutralizer, the treated area becomes grey colour. It remains only to wipe the stain with a dry cloth along with the remnants of rust.
2. Spray-aerosol based on zinc "Zincor-Avto". This agent is a degreasing solution capable of removing traces of corrosion from a metal surface. After applying the solution on the surface, a protective film.
3. Rust converter SF-1. The composition is based on phosphates. Used to treat steel, cast iron, aluminum and galvanized surfaces before applying varnish or paint. The modifier has an inhibitory effect, since the film that appears on the metal after its processing prolongs the service life of the painted surface for a period of 10-12 years.
4. Rust modifier "Berner". The drug has a deoxidizing effect. The basis of the modifier is molybdenum. The product is effective even on heavily rusted surfaces. For example, the converter processes rusty bolts that cannot be dismantled standard means. Available in the form of a spray.
5. Anti-corrosion agent B-52. This acid modifier is available as a gel. Its main advantage is the lack of spreading over the surface. After dissolving the rust, the remaining gel is washed off the metal.

Line of anti-corrosion products "WD-40"

The American company Rocket Chemical produces a line of corrosion control agents popular on the market - WD-40. Preparations are widely used by both professionals and home craftsmen.

The line includes five products: a long-acting inhibitor, protective lithium grease, waterproof silicone grease, spray and rust removal solution.

The drug is used for year-round protection of metal products located on the street. The manufacturing company guarantees rust protection for two years if the product is indoors, and for outdoor items, the warranty extends for a year.

The composition is a spray, including a vapor-phase anti-corrosion inhibitor, which creates a protective layer on the metal surface, preventing direct contact of the material with air and moisture. The inhibitor is recommended to be used to protect locks, gas cylinders, working tools, door hinges, technological chains and cables, steel doors, automotive parts. Also, the drug can be used to treat any other items, the operation of which is carried out in conditions of high humidity.

The drug is applied to the metal for the purpose of preventive protection, that is, in essence, it is an inhibitor. A thin protective film forms on the surface. Moreover, the film is not washed off under the action of precipitation, does not melt in the sun and does not freeze in cold weather.

In addition, lithium grease is often used to preserve products that are placed in a warehouse for long-term storage.

A characteristic feature of the lubricant is its ability to dry quickly. It is also worth noting that the grease leaves virtually no residue after lubricating parts. In addition to the described areas of use for inhibitors, silicone grease is recommended for the treatment of moving mechanisms. The lubricant does not contain petroleum products, and therefore does not damage rubber, plastic and vinyl surfaces. After drying, a transparent, non-sticky coating is formed.

The operation of the spray is based on the capillary principle, in accordance with which the liquid moves through small channels and cracks, despite the force of gravity. Due to this feature, the spray is suitable for treating hard-to-reach areas, where it is difficult to remove rust even by manual methods.

The spray can not only remove rust, but also act as an inhibitor, preventing it. reappearance in future. The drug is used to treat heavily rusted surfaces, including bolts and threaded connections. The spray is safe for non-metallic surfaces.

Rust remover

The content of the solution consists of non-toxic elements degradable by biological organisms. The solution is designed to remove the effects of corrosion from surfaces. To clean the metal from rust, the part is immersed in a container with a solution for 3-4 hours. If the product is very rusty, the procedure will take 7-8 hours. The solution is suitable both for processing miniature parts and for cleaning large-sized products (if there is an appropriate container).

Folk ways to remove rust

In addition to factory-made preparations, so-called rust removers can be used to remove rust. folk recipes. Most often we are talking about the Coca Cola drink, the Cilit cleaning agent, or a mixture of kerosene and paraffin.

Below is more information about each of the tools:

1. The effectiveness of the effect of the Coca Cola drink on rust is associated with the presence of phosphoric acid in the composition of the drink. To remove rust, you need to apply a drink to the problem area. You can use a soaked rag or a piece of foil. The method of immersion in a container with a drink is also used.
2. "Cilit" is often used to remove rust on household appliances in bathrooms and kitchens. In this case, the cleaning agent can be used to remove traces of corrosion on other metal objects, For example, automotive parts. However, it should be borne in mind that this tool can corrode the paint.
3. You can also clean the surface of rust with a solution of kerosene and paraffin in a ratio of 10 to 1. Before use, the composition must be kept for 24 hours. Next, the mixture is applied to the rusted place for 12 hours. The procedure is completed by cleaning the surface with a rag.

When dealing with chemicals safety precautions must be followed. First of all, it is necessary to protect the skin, respiratory organs and vision from the ingress of dangerous particles. You will need a respirator, goggles and gloves.

How to paint rusty gate you ask. For such purposes, there are so-called 3-in-one primer enamels for interior and exterior use. They perform a triple action: rust removal, priming and painting, protection against further corrosion. If a old paint on your gate began to peel off, then it is desirable to process such areas with emery (sand). Next, the surface is painted with such a three-component enamel. From domestic manufacturers I can recommend trademark"Spetsnaz". Pretty good paint.

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 covered with rust spots to a greater or lesser extent.

Repair manuals published in the past, including in 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 time-consuming step was precisely the removal of rust. This time-consuming work takes 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 rust, but covered a poorly prepared surface with ordinary paint, then soon the paint began to lag behind, and the iron continued to rust intensely.

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

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

1. The rust modifier reacts with rust to change 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 "paint on rust". In stores where paintwork is sold, you can ask about the availability of such paint. Its use Of course, loose rust will still have to be removed, along with dirt. But dense rust can not be touched. Paint "on rust" contains a modifier and a rust inhibitor; in addition, it contains epoxy acid based compounds to create a durable protective layer.

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

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

Metal products before use require not only decorative finishes 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 ingress of moisture on the metal, as a result of which it does not collapse upper layer. Today the market offers big choice goods, and in the article we will understand which goods deserved the most positive feedback and why.

Features and Specifications

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

• paint for metal and rust can be applied directly to the already formed corrosion;
• the product creates a reliable protective layer on the surface of the base, which is able to repel dirt, dust, moisture;
• the material is characterized by increased covering ability and good adhesion;
• the product provides long-term anti-corrosion protection;
• 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 outdoor, as well as internal works consists in the inability to process structures that are then subjected to high temperatures over 150°C. It is also strictly forbidden to contact painted objects with food or drinking water.

Market coloring compositions offers several options for rust mixtures, different 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 extremes, and the alkyd version should be used on structures that are not subject to heat, in this case an acrylic mixture is suitable. With the help of hammer products, it is possible to learn a rough coating with a metallic sheen.

Best Rust Paint for Exterior Metalwork

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

Rust paint for outdoor use is more of a universal means, because it is successfully used both indoors and outdoors. The product is applied to unpainted as well as painted surfaces, which consist of ferrous metal alloys. The special 3 in 1 formula includes a topcoat, primer and corrosion inhibitor, which significantly reduces the time to prepare the base.

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

Suitable paint for fences, piping system, furniture set. The base can be wood, metal, plastic, corrosion. The material is applied by means of an airbrush, a brush. Mechanical application is also possible. After complete drying, the interior and exterior coating acquires a glossy sheen. Washable Hammerite at optimum environment dries in 4-6 hours. The price for a container of 2.5 liters is 2500 rubles.

Prestige Primer enamel

Economical roof paint for rust and other metal structures, has a small expense - 60-120 gr./sq.m. It takes up to 40 minutes to dry, which is a big advantage.

Xylene, R-4, R-5 can be used as a solvent. The material has an anti-corrosion effect and a high resistance to various aggressive influences. Paint is applied to a galvanized roof, protections, pipeline system. The price for a container with a volume of 1 liter is 250 rubles.

The best paint for rust 3 in 1

If “3 in 1” is indicated on the can, this means that the main tasks will be performed during application - priming the surface, converting rust and creating a monolithic layer of enamel. Such compounds 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 the function of corrosion protection and decorative mixture at the same time. It is used for processing clean metal structures with rust up to 0.1 mm, as well as wood surfaces.

Hammer consistency after complete drying creates glossy finish with a chasing pattern. It should be remembered that the use of a mixture for non-ferrous metals is possible only after applying a primer. Glossy surface it is possible to create by means of a roller, brush, spray gun. The price for a container of 0.8 kg is 405 rubles.

Alpina paint is intended for interior and exterior work on the processing of metal products.
