Recently, there are more and more high-quality rust paints on sale, thanks to which anyone can not only perfectly update old metal products, but also save a lot of time at the same time. More recently, in order to update, for example, iron railings or grilles on windows, they had to be pre-treated with sandpaper or a grinder (to remove the old coating), primed the surface, and only then apply new enamel. Modern rust paints can be used without pre-treatment of the surface, which is very attractive to buyers.
Despite promising advertising, many buyers still have some distrust of this type of paint and varnish products. Should the manufacturers of these coatings be trusted or not? In fact, buyers should be aware that virtually all ferrous metals will rust quickly in the presence of water and oxygen. At the same time, it is not always and everywhere possible to regularly apply such protection methods for these structures as cleaning from rust, priming, applying paint and varnishmaterials. In this case, the only possible and most affordable way to treat surfaces is to apply paint over rust. Some of them are water-based, containing phosphoric acid. There is a two-component paint for metal and rust, containing additives based on epoxy or polyurethane resins and corrosion inhibitors.
Water-diluted compositions are the most environmentally friendly and cheap, but their use as "finish" coatings is possible only in cases where the surface of metal structures does not require high decorativeness, and they are used in conditions with relatively low environmental aggressiveness. Such compositions are best applied to pre-primed surfaces. The best paints for rust form coatings that isolate the metal surface as much as possible from aggressive substances, oxygen and water. They modify the chemical composition of the rust itself, which significantly slows down the destructive processes of corrosion. You should also not forget that, no matter how good such paint coatings are, loose rust must still be removed from the metal surface, since no paint can "bind" it and hold on for a long time.
There are many varieties of anti-corrosion coatings. One of the most popular products of this kind is Hammerite rust paint. Just apply itbecause it performs several functions at the same time: it transforms the corrosion layer, it is a primer and a top coat. It is noteworthy that Hammerite paint in several layers can be applied in one day. This paint coating provides metal structures with a decorative look and good protection. This paint is not intended for industrial use. The best effect is achieved when applying a layer with a thickness of at least 100 microns. Hamerite paints are able to repel moisture, since they contain silicones. This coating is based on a complex of resins designed to block rust. It contains modified alkyds that provide high adhesion to metal surfaces. The rapidly evaporating solvents contained in the Hamerite Rust Paint contribute to its rapid drying. Glass microparticles reinforce the waterproof barrier. This paint is applied only on a non-peelable surface that has been painted at least six months before. Hammerite paint is not compatible with bitumen-based compounds. When applied to non-ferrous metals, pre-priming is required.
