Exterior metal and rust paints are used for surfaces that cover large areas or have complex shapes that make them difficult or impossible to completely remove corrosion from. Such compositions easily adhere to the surface of rusty metal and form coatings that are resistant to wear and abrasion.
Where to buy good anti-corrosion paint for rust? In the Arlind online store you will find the best wear-resistant paints for galvanized, non-galvanized metal and rust for exterior work at competitive prices with delivery in Moscow and throughout Russia. Our assortment includes products from Tikkurila, Hammerite, Teknos, Tex and other brands.
Types of anti-corrosion paints for metal
Based on their composition, metal and rust-resistant paints are divided into the following types:
- Acrylic water-dispersion paints . They are produced on the basis of acrylic polymers and also contain anti-corrosion, modifying and other components. They are convenient because they have no smell. Typically, before applying acrylic wear-resistant paints, manufacturers recommend priming the metal.
- Alkyd paints for metal and rust . They have high adhesion to the surface. You can choose such compositions at a low price; manufacturers recommend applying some products to galvanized or non-galvanized rusty metal without prior priming.
- Polyurethane paints for metal . The cost of such compositions, on average, is slightly higher than other types of products. Most often used for interior work. They form a “silky” surface that is resistant not only to impact loads, but also to chemical influences.
- Hammer anti-corrosion paints for metal (including rust). Ideal for coating ferrous metals. They create the effect of “hammer” embossing and are very effective against corrosion. They contain epoxy, acrylic, alkyd-styrene components, as well as silicone resins and metal pigments.

What to consider when choosing a material
Paint for protecting metal parts from corrosion is too general a definition. Hundreds of coatings formally answer this request. But it may turn out that the purchased product will not work under your conditions. To prevent this from happening, we advise you to consider:
- Working conditions of paintwork materials. If structures operate in a polluted atmosphere - near roads or production centers - then chemical-resistant enamel is needed. Regular formulations will not last long. Not all compounds are suitable for protecting metal parts from rust in sea or fresh water.
- Condition of the substrate. Adhesion is not a constant characteristic. It may vary depending on the type of coating. For example, if there are traces of rust on the base, then you need to use compounds with a high level of adhesion. It is advisable that the manufacturer explicitly indicate what can be applied directly over rust. For well-cleaned parts, products with less adhesion are suitable.
- Life time. Cheap products usually do not last longer than 2-4 years. And even during this period, the layer may begin to fade or become cracked. In certain situations, such fragility will be appropriate. For example, when painting benches, garbage bins or other similar structures. They can always be repainted. But to protect building metal structures from corrosion, these paints should not be chosen. To prevent rust from developing, the steel will have to be repainted every 3-4 years. And these are additional costs. Materials that retain their qualities for 10-15 years are considered good.
- Substrate temperature. The material that can be applied to the roof may not be suitable for heating radiators heated to high temperatures. A similar principle works in the case of low base temperatures (- 50 or - 60 degrees). The operating range is usually indicated on the packaging or in the product description.
- Appearance. The texture of the layer is another factor. It becomes important if you buy enamel not only for rust treatment, but also for aesthetic purposes. Road or rail tanks, ladders, process equipment or machinery. Everything that people constantly see should be beautiful. The matte film does not create glare, hiding the unevenness of the material. Gloss - makes the structure “elegant”, but at the same time makes any defects of the substrate visible - dents, bends, etc.
Alkyd weatherproof anti-corrosion paint Tikkurila Panssarimaali
Panssarimaali metal paint from Tikkurila contains highly effective anti-corrosion pigments, so it can be applied over rust. Used for outdoor work. The product can be purchased for a durable finish on pre-primed steel, aluminum, and galvanized metal surfaces. Suitable for roofs, drainpipes, railings, and other metal structures. The composition is successfully used in humid climates and in industrial environments.
The coating formed by Panssarimaali metal and rust paint significantly slows down the corrosion process. It is chemically resistant: it can withstand exposure to alcohol, lubricating oils, turpentine and white spirit. After complete drying, the surface can be washed using conventional detergents.
Recommendations from experts
Considering the huge number of metal surfaces, experts recommend several important points to consider:
- When painting radiators and heating pipes, it is better to choose heat-resistant types of paints and varnishes;
- It is better to paint heating pipes before the start of the heating season;
- Furnace parts are also painted with materials that are resistant to high temperatures;
- Surfaces made of non-ferrous metals must be coated with a special coating. soils;
- When working with industrial objects in the fresh air, organic solvents are suitable.
Anti-rust coatings for the population are modern protective products that allow you to extend the service life of metal products. The use of these special compounds allows you to save a lot of time on cleaning the coating. Using anti-corrosion enamel on metal, you can get good results with minimal investment.

Primer paint for metal and rust 3 in 1 Alpina Direkt auf Rost from Caparol
Alpina Direkt auf Rost paint is used for painting iron and steel, including rusty metal. Suitable for external and internal work, not intended for work on galvanized metal. It is a “three in one” product: it combines the properties of a primer, anti-corrosion and decorative finishing coating. The paint is based on alkyd resins; it does not contain lead compounds, chromates and other harmful components, dries quickly, and creates a durable, long-lasting dirt-repellent coating. The composition includes active pigments against corrosion.
Helpful information
Tips for painting a car:
- The composition should not be applied to a loose layer of rust; it must be cleaned off.
- If the paint contains a primer, then it is used as a mono product. The number of layers must be at least 3.
- The coating can only be applied to a dry surface.
- When painting a large area, the paint is applied in stripes. In this case, each line must overlap the previous one.

About corrosion and technologies to combat it
The main significant disadvantage of the metal is its poor resistance to corrosion processes. For this reason, not only the appearance of the metal structure significantly deteriorates, but also their service life is reduced. To understand how anti-rust paint works, you need to know a little about rust. It is formed as a result of oxidative processes. Metal is susceptible to oxidation when there is a lot of moisture in the air.
Under the influence of moisture vapor, metal loses its strength and attractiveness. If oxidation processes progress and begin to penetrate deep into the structure of the material, structures made from it will collapse from the inside.
Corrosion processes attract moisture, which is retained in metals due to their porous structure.
To combat corrosion, there are traditional protective methods, most of which involve thorough cleaning of the effects of corrosion processes. Then the metal surface is treated with an anti-corrosion primer and coated with paint.
But, from the point of view of financial and time costs, cleaning, priming and painting are not always justified. This has necessitated the need for new, more cost-effective means that make it possible to provide reliable surface protection with less labor intensity. Now such means exist.
To protect metal products from progressive corrosion processes, specialized paint and varnish products are used, designed to prevent oxidative processes.
