After some time, the metal surface begins to corrode and this is a serious problem. At the moment when the process has already begun, there is a way to completely eliminate all signs of rust - mechanically with anti-corrosion treatment and further painting. Still, there are difficult places that cannot be machined and rust paints are used to make it easier.
Most specialized stores offer popular branded rust paints with different compositions, capabilities and prices. And for a convenient independent choice, we have prepared an article with a rating, where you can familiarize yourself with the best paints, their characteristics, advantages and disadvantages, so that you can be prepared before purchasing the material.
General information
Rust-resistant paint must be applied in thin layers to a metal surface susceptible to corrosion, since this paint product with a composite composition forms a protective film that forms a strong adhesion. This excellent material not only serves as a protector for metal substrates, but also paints it in the desired color, without the need to clean and level the metal products before application. The principle of the paint works as a final, final treatment for ferrous or non-ferrous metals that have been exposed to corrosion.
Fencing before and after painting
The content of chemical components in the paint ensures rapid drying and the formation of a dense, reliable protective layer. The composition contains alkyd resins and special concentrated polymer additives.
Advantages of using rust paint followed by conversion:
- prevention of repeated corrosion formation;
- surface coating to create your own color appearance;
- after application, a high-quality moisture-dirt-repellent layer is formed;
- adhesive properties enhance adhesion to the base, which leads to long service life;
- withstand high operating temperatures;
- a wide range of palettes allows you to choose the desired shade;
- dry quickly.
There are also disadvantages to inappropriate processing of metal surfaces when heated to more than 150°:
- after fresh application, protect the painted areas from moisture;
- There are compositions containing toxic components and they are prohibited for use in residential areas.

Economical consumption Anti-corrosion enamel has a large amount of pigment in its composition and a thick consistency. After dilution, it is advantageous to use it for painting large structures, and also apply it as a primer.
- Characteristics
Price: 1750 rub./2.5 l
- Country: Germany (produced in Russia)
- Consumption: 1 l/12 sq. m
- Complete drying time: 24 hours.
Alkyd enamel 3 in 1 contains a decorative coating, anti-corrosion primer, and rust converter, so it is good for priming and painting new and corroded metal products. Due to its increased density, the material is difficult to apply, and the manufacturer recommends diluting it with white spirit. The paint itself does not smell, but in combination with a solvent a pungent odor appears, so it is more suitable for outdoor work. To prevent the material from forming smudges and drying quickly, reviews recommend diluting it with solvent in a ratio of 2:1 (manufacturer’s recommendation is 1:1). There are also complaints about the color palette - there is plenty to choose from, but the colors are too dark.
Advantages and disadvantages
- Pigment-rich 3 in 1 composition
- Favorable consumption and price
- Painting over rust
- Not tinted
- Dries slowly

Because of this, it is recommended to paint in 1 layer; if necessary, you can add a 2nd, but no later than 2 hours after the 1st. The resulting coating lasts a long time, at least 5 years, and is stable, since it is not afraid of UV radiation.
