Reacts chemically with rust and effectively stops further corrosion
On drying the creamy white coating is converted to a firmly adherent bluish-black film
Can be overcoated with most types of solvent borne and waterborne emulsion paints such as alkyds, acrylics, epoxies, polyurethanes and vinyl systems
To neutralise red rust and give corrosion protection to rusted mild steel surfaces in areas where it is impractical/impossible to remove rust completely, such as burglar bars, fencing and structural steel
