Rating of paints for metal and rust

Over time, even good steel, cast iron and other metal surfaces on the same car begin to rust. To avoid this, it is required to periodically carry out anti-corrosion treatment of products. Alternatively, you can choose the best paint for rust, which is suitable for painting not only clean, but also oxidized areas.

Types and characteristics of paints for rust

The mechanism of the appearance and growth of corrosion is simple. The unprotected metal surface, 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 of the trouble. The pores of the rusted metal attract moisture even more and better keep it inside, accelerating the destructive processes. As a result, the product loses its strength, and its service life decreases.

Conventional anti-corrosion paints and varnishes protect the metal well from rusting, 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 dries with paint.

The type of metal being processed.

If it is necessary to paint heating pipes or radiators, it is necessary to choose a heat-resistant composition that can be operated at temperatures up to 150 degrees. Furnace elements are treated with materials that can withstand temperatures up to 500 degrees.
Painting temperature.
Corrosion site area and propagation rate.
The need to use a solvent for dilution.
Drying time depending on the place of painting. The value varies from five hours or more, depending on the properties.
Painting method - roller, brush, spray or aerosol can.
The density of the protective film.
The level of toxicity with the need to use protective equipment.
Planned consumption.
The desired color, gloss or dullness are selected according to the interior fit. Gray-black shades are suitable for non-residential premises, and where people are located, it is better to choose brighter colors.
The choice of which company is better depends on the goal achieved as a result of the painting, as well as the finances. Some have premium materials with high parameters, while others offer budget compositions that do not differ in achievements.
