The use of hammer paint is allowed without additional use of a primer. The mixture is applied in three layers. This corrosion resistant paint can be used both indoors and outdoors. The main thing is that the temperature of the metal painted with it does not rise above 150 degrees

Selection Tips
In order for the process of painting metal structures with special rust paints to give the desired result, it is necessary to take into account some of the nuances of the choice of these compositions.
- The type of surface to be painted must be taken into account. So, for the roof, it is necessary to choose paints that are not prone to fire and easily tolerate strong temperature changes.
- The colder it is outside or indoors, the more resistant to subzero temperatures the paint should be, otherwise the mixture will not be able to fully fulfill its protective and restorative functions.
- Rust paints should be purchased at specialized retail outlets. It is better to give preference to products of proven brands.
- The degree of rust damage to the metal should be taken into account. The more corrosion on its surface, the more aggressive in composition the paint should be. Experts strongly recommend treating metal with a primer if its surface is more than 50% rusty.
- Be sure to consider when choosing and recommendations for the use of this paint and varnish mixture. If it is indicated that it is intended only for indoor use, then painting metal with it outdoors, even in several layers, will not give the desired result.
- The level of toxicity of paint for rust is one of the key selection criteria. The higher it is, the more dangerous this composition is for humans. Highly toxic paints can only be used outdoors, and it is imperative to wear a respirator or face shield.
All modern rust paints have a high-quality composition and a rich palette of shades. This allows, in a fairly short time, to reanimate even metal structures of any type that are severely damaged by corrosion.
