Anti-corrosive paintfor metal can be applied directly to the corroded metal. By choosing this paint, there is no need to apply a primer or a base coat beforehand.

Metal paints have different purposes. Some of them can only be painted indoors, while others can only be used outdoors. Keep in mind that metal paints intended for indoors do not have weather resistance. Some exterior metal paints, on the other hand, may give off substances that are harmful to health.
Proper painting of a metal coating affects the durability of the paint. Therefore, it is important to properly prepare the material to be painted, e.g. by removing the old paint.
Before you start painting, you should first roughen the surface of the metal with sandpaper. Then clean the surface from dust and degrease it, e.g. with extraction gasoline, benzine or solvent. The metal surface should be slightly rough after cleaning.
Metal paints are best applied with a roller or pressurized spray gun. When painting small parts, spray paint will work best. To achieve the desired effect, the surface should be painted twice. The second layer of paint must be applied only after the first one has dried out.
When painting, remember about the right temperature in the room – the best temperature range is 15-20°C.
