Today's construction market offers customers a wide choice various materials for metal processing. In this regard, homeowners often have the question of which metal paint is best. To answer this, you need to understand the types of such products and their properties.
They are divided into two subspecies:
In the photo - enamel for a metal surface
They began to be used for coloring metals relatively recently. But they have already gained considerable popularity. This is explained by the fact that this coating is very durable. In addition, it is not subject to cracking, fading and provides good protection against corrosion.
Another plus is that it can withstand high temperatures. Therefore, it can be used to treat radiators of heating systems.
The next advantages are environmental friendliness and non-flammability. This mixture does not have unpleasant odor and until it dries, it can be washed off hands and tools using ordinary water. Thus, it is about her that we can say that this is the most best paint for metal.
When choosing a suitable paint composition for a metal surface, you must first decide whether it will be exposed to high temperatures. It should be noted that alkyd mixtures can withstand no more than 80°C, acrylic mixtures - up to 120°C.
There are also specialized compounds that can withstand very high temperatures. In particular, these include epoxy-bitumen solutions and products based on silicone resins. The first of them are designed for temperatures up to 400°C, the second – up to 600°C.
Note! For interior work, choose acrylic compositions. They are safe for health and do not have a strong odor.
As for external work, enamels are quite suitable for them. They are toxic, but at the same time they fit well on a metal surface. To protect against corrosion, primer enamels can also be used.
Advice! When purchasing Russian-made materials, give preference to those that are manufactured in accordance with state standards. Metal paint according to GOST, as a rule, has higher performance characteristics and good quality.
Products manufactured under this name are invariably very popular among home craftsmen. The coating formed by such materials has good wear resistance. It also perfectly tolerates the effects of lubricating oils and various fats.
This brand produces compounds intended for both internal and external work. For the first of them, paint consumption per 1 m2 of metal is 1 liter per 8-10 m², for the second - 1 liter per 10-14 m².
Tikkurila's product range also includes heat-resistant mixtures. They are able to withstand temperatures up to 400°C.
The metal coating produced under this brand can be applied directly to rust. No preliminary cleaning or priming of the surface is required.
This composition is equally suitable for both ferrous and non-ferrous metals. It has a wide palette of colors. Thanks to this, each homeowner will be able to choose the tone that suits them.
In addition to rust, such a coating can be applied to a surface painted with almost any composition. The only exceptions are bitumen or powder mixtures.
To summarize, it should be noted that Hamerite has only one drawback. This is its high price.
This manufacturer produces 3 in 1 primer-enamel, which is intended for metal. This composition is not only decorative, but also a protective coating. Therefore, it can be applied to rust-covered coatings without prior preparation or priming.
Paint consumption rate per 1m2 for metal in this case ranges from 80 to 120 ml/m². Of course, this is subject to application of the coating in one layer. With a larger number, the material consumption will increase manifold.
This composition is used for. Moreover, it can be applied to both matte and glossy surfaces.
The coating obtained with its help is resistant to sudden temperature changes and other adverse effects. external environment. In addition, it dries quickly and can be applied at temperatures down to -10°C.
Advice! Do not use this primer-enamel for heating surfaces, as well as those that have been painted with nitro enamel. In the first case, an unpleasant odor may appear, and in the second, swelling of the applied coating may occur.
In order for the applied composition to last long enough on the metal surface, it must be carefully prepared. First of all, clean it with your own hands from rust, dirt and old, peeling coating.
To do this, you will need a wire brush, scraper or sandpaper. A warm soapy solution will help you remove soot and other contaminants. After finishing work, the surface is washed clean water and dried.
Advice! You can quickly clean a large surface using an oxy-acetylene torch. In its flame, the old coating will simply burn, and rust and combustion products will peel off.
Treating metal with a primer allows you to achieve two goals:
It should be taken into account that different metals require different primers:
The instructions supplied with it will help you understand the purpose and features of a particular primer. Regarding application of this material, it is usually done using a roller or brush. In some cases, it is possible to use methods such as dipping and pouring.
Everyone knows what “rust” is, even children. In appearance it cannot be confused with anything else. But, unfortunately, the loss of an attractive appearance by metal structures is far from the biggest nuisance associated with the appearance of unsightly flaky red spots. What’s much worse is that rusting is a corrosive process that destroys the structure of the metal.
If you leave everything to chance and do not fight rust, then metal products and structures are destroyed quite quickly, losing their bearing capacity. Of course, it is best to prevent metal corrosion by promptly protecting it from moisture and exposure to other substances that can lead to the rapid appearance of rust. But what if it has already appeared? Is it possible to stop the corrosion process by initial stage? And, if possible, then how?
The simplest and in an accessible way in this situation, the method of isolating the metal surface from factors causing corrosion is to apply protective coating.
This is why all metal parts are usually painted.
But are all paints equally effective at protecting a surface that has already been corroded to one degree or another? No, not all. Moreover, if the structure is located in the open air - that is, it is exposed to negative impacts constantly.
We will consider only those compositions that are intended not just for painting metal, but specifically for protecting it from corrosion, including that which has already begun.
Anti-corrosion compounds are designed to protect the metal from the destructive effects of oxygen and moisture, which are the cause of rust.
It should be noted that all anti-corrosion paints are used only for surfaces with minimal traces of corrosion.
Paints for rust Usually, the wrong areas of the structure are applied that already show obvious signs of oxidation. The use of such paints allows you to avoid the lengthy and costly process of preparing a rusty surface for painting.
Hammer paints contain aluminum powder and glass ( fine fraction). They also contain silicone oil. The paints have excellent adhesion and are well suited for painting metal, both in need of anti-corrosion protection and with traces of rust.
These compositions are remarkable in that they give the surface a high decorative quality. Hammer paints have a wide color scheme, dry quickly, but require strict application technology.
In order to make the right choice of the coloring composition that you are going to use for protection metal structures located outdoors, certain factors must be taken into account.
If the surface has minimal traces of corrosion, then inexpensive compounds can be used. If the degree of damage is 35-40%, then you need to purchase more effective (and therefore more expensive) paints.
If it is not possible to buy a highly effective, expensive composition, then you can go the other way: purchase inexpensive anti-corrosion paint, but apply it only after treating the metal surface with a rust converter and a primer-modifier.
Very important: the paint container must indicate that it is “weather resistant.”
Depending on the type of paint chosen, surface preparation for painting may vary, so we will consider different options.
You can paint metal different ways– brush, roller, spray gun. The main thing here is the requirement to distribute the paint over the surface as evenly as possible.
Painting is carried out according to the instructions given on the paint can. Usually it is done in 2-4 layers with intermediate drying of each of them.
Such paint compositions dry quite quickly - from half an hour to several hours.
Among the many compositions for metal protection, there are the most popular ones, tested by specialists and ordinary consumers.
Thus, there are a sufficient number of paint compositions on the market that can protect metal products and structures from corrosion, as well as stop it.
The cost of paints marked “for rust” is higher than conventional anti-corrosion compounds, but their use allows you to reduce the time required for work and also reliably protect metal parts from destruction.
Any metal structures that are already ready or just being prepared for installation require protection from external influences. This is especially necessary if the product will be located outdoors. In this case, one of the options for surface treatment is metal paint. The product can simultaneously perform 2 functions - decorative and protective, but for this you need to choose it correctly.

Any paint for metal against rust is anti-corrosion, the only difference between them is the degree of effect and the possibility of application directly to areas with pockets of corrosion. In general, each option proposed by the manufacturers will reliably protect the base from the formation of growths. In addition to this property, the product also has a number of features.
First of all, it should be noted fire-resistant paint, which copes well with protective properties, while at the same time acting as a barrier against temperature effects. This material is successfully used in processing various designs that are regularly exposed to heat or are located close to a heat source. The entire range can be divided into 5 main varieties, depending on the composition:
This information will be sufficient to complete the right choice. But when it comes to choosing a manufacturer, experts recommend using the ratings of the best, according to builders, paints for metal and rust.
This product belongs to the 3 in 1 category. This means that it performs 3 functions at once - anti-corrosion primer, sublayer and finishing coat. The only condition is that the soft layer must be removed first, otherwise it will peel off along with the finish.
Hammerite paint for metal and rust is considered universal because it is produced using 3 in 1 technology. Thanks to this factor, it includes a primer, corrosion inhibitors and a topcoat. This product does not require additional preparatory work, which reduces time costs. The material is resistant to abrasion, humidity and temperature influences.
Hammerite 3 in 1
The heat-resistant coloring consistency dries quickly enough, so to create the second layer you need to wait only 4-6 hours from the moment of applying the first. Alkyd material is widely used in the industrial sector, as well as in domestic conditions. Paint for galvanized metal is also suitable for painting fences, pipeline systems, and furniture. In addition, metal alloys, wood, and plastic can be used as a base. The mixture can be applied directly to the corrosion using a brush or spray. A 2.5 liter Hammerite capacity is sold at a price of 2500-2700 rubles.
Epoxy-polyester powder paint for metal it has high characteristics against chemical attack and darkening at elevated temperatures. Does not tolerate direct sunlight, so it is used indoors.
Most often it is used for cladding household equipment, retail fittings, shelving, furniture components and other accessories. The material is produced not only in white; there is also paint in silver, yellow, blue, green and other shades. Price for 2.5 kg - 1050 rubles.
Products in this category will not turn yellow or lose their gloss when exposed to direct sunlight, and are not susceptible to oxidation. The maximum service life is 5 years, after which the surface must be re-coated.
This is a quick-drying paint for metal, which has a high level of adhesion to the substrate, as well as short term drying. It takes up to 60 minutes to completely harden, which is considered a big plus. The coating has good parameters corrosion protection and weather resistance. The manufacturer recommends, if necessary, diluting the mixture with xylene, R-5 and R-4.
When applying the product in one layer, its consumption varies between 60-120 g/sq.m. It is packaged in 1000 ml containers, the price of which varies between 250 rubles.
Heat-resistant paint for metal up to 900 degrees from domestic manufacturer may be used for painting elements that are operated not only with increased heat transfer, but also with severe frosts up to -65°C. The material is released in 26 color solutions, while the temperature stability is not the same for every tone, this should be taken into account when choosing.
Matte black paint for metal can withstand 900°C, other shades have a slightly lower rating. The fire retardant mixture is packaged in containers of various sizes, including spray cans. 800 gr. costs about 400-550 rubles.
The name "hammer" is derived from the visual effect created. After drying, the surface becomes embossed with a three-dimensional pattern that imitates hammering. It perfectly protects metal from corrosion, retains its design for 5-6 years even in direct sunlight.
Alkyd dye has high decorative properties, but at the same time regularly performs protective functions. The material can be applied to structures cleaned from corrosion, as well as directly to rust. The main thing to consider here is that the build-up layer should not exceed 0.1 mm in thickness. In addition, the product is suitable for cladding wood substrates.

Lacra Hammer Effect
When hammered products dry, they form a uniform glossy coating with slight relief and a hand-chased pattern. If you plan to apply the mixture to products made of non-ferrous alloys, their surface must first be treated with primer. The work uses rollers, brushes and spray guns. The minimum volume of 1 liter costs 400-430 rubles.
The quick-drying, odorless material is made on the basis of alkyd components; as a result of application, it forms a uniform layer with a glossy surface. It is used quite economically, one liter is enough to process 15 sq.m.
The product is packaged in 750 ml tin containers. The odorless dye is applied to both metal and galvanized surfaces, wood, plastic, and concrete. Can be used inside and outside the building. Color palette contains 24 shades. The price for 750 ml varies within 240 rubles.
The symbol on the package “3 in 1” means that the composition includes components that neutralize rust, prime the base and, in fact, the coloring enamel itself. Convenient and quick to use, there is no need to pre-prepare the base, but only if the rust is not soft and its layer does not exceed 0.1 mm. Here you will have to clean it with a wire brush and then cover it without primer.
Alpina is used for processing metal structures located both indoors and outdoors. The product simultaneously creates a decorative and protective cladding that will not only look attractive, but also protect the base from moisture or corrosion.

Rollers and brushes are used for work. Material presented at 9 different shades. Price for 2.5 liters - 1950-2100 rubles.
Alkyd anti-corrosion mixture creates glossy surface with uniform distribution of pigment even if the product is applied in one layer. The material is resistant to atmospheric influences and temperature changes.
The main parameters of metal paint for exterior work are as follows:
A container with a volume of 2.5 liters costs up to 1,500 rubles.
VIDEO: How to properly paint galvanized metal
The mechanism of the appearance and growth of corrosion is simple. The unprotected surface of the metal, interacting with water and oxygen, begins to oxidize. Its structure changes, becomes loose and porous, and loses its visual appeal.
But external manifestations of corrosion are half the trouble. The pores of rusted metal attract moisture even more and better retain it inside, accelerating destructive processes. As a result, the product loses strength and its service life is reduced.
Conventional anti-corrosion paints and varnishes protect metal well from rust, creating a moisture-impermeable film on its surface. But in order for them to adhere well to the surface and perform their functions efficiently, the products must be cleaned of the destroyed layer before applying them, then covered with an anti-corrosion primer, and only after it has dried with paint.
Multi-stage processing takes too much time, requires large material and physical costs, which is not always justified. A less labor-intensive, and often more economically advantageous, method of protecting metal has become the use of special paints, which can be applied directly to rust, bypassing the preparatory steps.
Packages with this paint are marked “3 in 1”. This means that the composition performs three functions at once:
Rust paint has several important advantages, many of which are not available in conventional decorative compositions intended for metal products.
Just like regular ones decorative coverings, paints that can be applied directly to rust are available in the most different colors and shades.
The properties and scope of application of rust paints are determined by their composition. And mainly - the type of base. Based on this criterion, they are divided into oil, alkyd, acrylic, and epoxy.

Anti-corrosion paints
The consumption of paint compositions depends on the method of application. This can be done using the traditional method - with a roller or brush. If the paint can be sprayed, its consumption is reduced to 20-30%. And aerosol paints in spray cans are characterized by increased consumption.
The choice of method depends on the type of surface to be painted. For example, solid metal parts with a large area to be painted can be painted as desired, but openwork parts are more convenient to spray paint on. It is also easier to paint hard-to-reach places with a spray bottle.
Note. At proper preparation surface and compliance with the painting conditions, the durability of the finished coating will be the same regardless of the method of applying the paint.
Among the many brands of special rust paints, there are those that are especially popular. It is determined not only by positive customer reviews, but also by sales volume.
This brand is a confident leader, despite its fairly decent price. This is due to the quality of the coating, its durability, beautiful texture and versatility. Hammerite anti-corrosion paints are used for decorative finishing ferrous, galvanized and non-ferrous metals, wood, plastic. They are used for finishing external and internal structures. Apply to new and previously painted surfaces.
When choosing paint of this brand, you should pay attention to the series.
Another effective one protective agent with a hammer consistency. Made on an alkyd-styrene base, it is characterized by its low price and good adhesion to metal surfaces with a rust layer thickness of up to 0.1 mm. Can also be used for painting wooden structures, creating a coating with a metallic sheen on them.
"Lakra" Hammer Effect
Universal paint from the well-known company Caparol for decorating metal surfaces indoors and outdoors. It is easy to apply and has good resistance to fading.
Alkyd paint Nerzhamet is available in regular form and in aerosol cans. It contains polymer inclusions, is very easy to apply, dries quickly and adheres well to the rust-affected surface, forming a hard semi-gloss film. Its service life without the need to renew the coating is six years.
Another inexpensive domestic product, characterized by a high drying speed, high resistance to moisture and other aggressive environments, economical consumption, amounting to a maximum of 120 grams per square meter. Diluted with solvents such as xylene or R-4 to the desired consistency.
"Prestige". Primer-enamel
This paint is actively used for finishing galvanized metal roofs, external pipelines and fences.
Like most other alkyd enamels, this composition can be applied by any means. Available in packaging of different volumes: buckets, jars, aerosol cans. It is used to paint external structures made of steel and cast iron, including those with old paintwork. Penetrates well into the deteriorating metal structure and blocks the spread of rust.
"Stop rust"
Even galvanized steel, when exposed to precipitation, sunlight and aggressive impurities in the air, will corrode over time. To protect it, a special 3 in 1 product “Tsikrol” has been developed, which has high adhesion to such surfaces.
It consists of acrylic resins, organic-based solvents and additives that increase the enamel's resistance to wear, moisture, low temperatures, corrosion and other atmospheric influences. It has good coverage, water-repellent properties and the ability to dry quickly after application.
Advice. The paint contains volatile toxins that evaporate into the air from the fresh, not dried composition. Therefore, while working with this product, it is necessary to protect the respiratory system and skin.
Not all paints can resist rust high temperatures. They are designed for heating no higher than 40-60 degrees. But metal structures such as stoves, barbecues, fireplaces, pipes and radiators, car parts and other equipment also need protection from corrosion.
To decorate them you need to use heat-resistant and heat-resistant paints. The degree of their stability is determined by the composition of the components. Among these dyes there are also several different types.
| Types of heat-resistant paints | Composition and application |
|---|---|
 | Alkyd paints with the addition of zinc and phosphate compounds are designed to withstand temperatures up to 100 degrees. They can be used to color elements heating system– radiators and pipes that do not heat above 90 degrees. |
 | Epoxy compounds can withstand temperatures up to 200 degrees. Some of them require an anti-corrosion primer to be applied. Can be used to create a protective coating on components and parts of technical equipment. |
 | Epoxy ester and ethyl silicate paint compositions with metal powder as additives can withstand a maximum temperature of 400 degrees. And one-component silicone based on polymer resins - up to 650 degrees. This suitable paints for protective and decorative finishing of outdoor barbecues. |
 | The most heat-resistant paints contain particles composite materials and heat-resistant glass. They are used to paint metal stoves and fireplaces that can heat up to 800-1000 degrees. |
Heat-resistant paints
It is important! In the vast majority of cases, all these structures should be painted in a cold state, and heated after the coating has completely dried. Although there are paints that require heat to polymerize. Therefore, carefully read the instructions with recommendations for use.
Three-in-one metal paints can be applied to any metal structures, even those damaged by corrosion. In this case, pre-treatment with a special primer is not necessary, because such paints already have the properties of this composition. In addition, they convert rust into a monolithic layer and are excellent decorative materials.
Thanks to these features, painting any metal structures with such paint is much easier than with conventional compositions that require careful preliminary preparation of the metal surface.
Regardless of the application method, the work procedure consists of only a few steps.
Step 1.The metal surface is cleaned from dirt and the flaking upper rusty layer using a stiff brush, spatula or sandpaper with coarse abrasive.
Step 2.The cleaned product is wiped with a solvent, moistening a cloth or sponge in it. And let it dry.
Step 3.Preparing the paint involves mixing it thoroughly. Or shaking the can if using an aerosol. It is advisable to rub a brush with natural bristles on sandpaper so that bristles that do not adhere well fall out and do not remain on the paint coating.
Step 4.The paint is applied to the surface in an even layer and allowed to dry for the time specified in the instructions.
Step 5.Then apply a second layer, trying to avoid drips.
If the paint is applied or sprayed from a can, then more layers will be required - at least three. Between them it is necessary to observe a time interval for drying.
Spray gun
The can or gun should be shaken before work and periodically during work, and the sprayer should be kept at a distance of 20 cm from the surface to be painted.
Modern market finishing materials is constantly updated with new products that simplify the work of finishers and have improved decorative and performance characteristics. Rust paint is a prime example of such innovation.
Among the compositions that prevent the development of corrosion, there are priming, painting, and enamel primers. They all have the same property, but they have different time drying, color, shade, composition and rules of use.
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, wanting to receive saturated color, it is enough to apply the second layer of “Rusteater”.
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 high-quality coating At least two layers are required. This composition is recommended for use only in warm, not damp weather.
If you don’t have the time or desire to pre-clean the metal, you can use Nerzhamet 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.
