To get a regular paint to look smooth, the surface would have to be prepared first, for example, by spackling, sanding, grinding or polishing. With hammer paint, this step can be omitted. Some hammer paints (e.g. by Hammerite) are formulated to be usable directly on rusted steel without surface preparation other than brushing to remove the ...
Hammerite products includes rust prevention and restoration paint, and are based on zinc phosphate as the active ingredient. Their products include interior and exterior paints as well as special metal primers. Many of these paints feature a hammered look, hence the name of the company.
Rusted corrugated steel roof. Galvanized steel can last for many decades if other supplementary measures are maintained, such as paint coatings and additional sacrificial anodes. Corrosion in non-salty environments is caused mainly by levels of sulfur dioxide in the air. [10]
The most common conversion coating processes for metal parts with industrial use include Chromate (aluminum, steel) Phosphate (steel) Bluing (steel) Black oxide (steel) Anodizing (aluminum) Stannate (magnesium) [5] Molybdate (zinc, zinc-nickel) [6] [7] Zirconate (steel, aluminum, magnesium, galvanized steel).

Weathering steel, often referred to by the genericised trademark COR-TEN steel and sometimes written without the hyphen as corten steel, is a group of steel alloys which were developed to eliminate the need for painting by forming a stable external layer of rust. U.S. Steel (USS) holds the registered trademark on the name COR-TEN. [7]
In comparison to a zinc (galvanized) coating galvannealed has better spot weldability, and is paintable, [4] Due to iron present in the surface alloy phase galvanneal develops a reddish patina in moist environments - it is generally used painted. [5] Zinc phosphate coating is a common pre-painting surface treatment. [4]
