Any metal structure in the open air suffers from many negative factors. But, the most dangerous, which leads to a decrease in strength and a decrease in the operational life, is considered to be rust. Immediately after installation, in some areas or even throughout the entire structure, metal corrosion can appear. Primer enamel for rust , will help create an insurmountable obstacle to water.
How paint can help
Good, high-quality paint is able to give any metal structure not only an attractive aesthetic appearance, but also preserve all the technical characteristics of the metal for several years. The main advantages of a quality metal paint that can be applied directly to rust include:
- there is no need to specially prepare the surface;
- the finished coating not only repels water and dirt, but also resists the sun's rays;
- does not deteriorate under the influence of low and high temperatures;
- resists mechanical destruction;
- a durable coating that does not require repair every year;
- a wide range of colors and shades available.
The only drawback of paint is for rust, it should not come into contact with surfaces that directly deliver or store water for food.
How to properly paint the coating
In order for the paint to hold on to rusty metal as firmly as possible, a few simple rules must be followed. By adhering to them, the manufacturer of his product can guarantee that the coating will meet all the stated standards:
- Surface preparation is minimal. Free from debris, dry and free from any solvent.
- As mentioned above, there is no reason to get rid of rust. Special chemically active substances transform it into a part of the soil. The only thing that needs to be done is to clean the places that have corrosion pits.
- The optimum temperature of the air and the surface for applying paint is +20 degrees. Deviations can be both up and down, but no more than 5 degrees.
- Priming is not necessary, the paint itself forms a strong bond with the metal.
