Crown Trade Protective Coatings T-Wash
Crown Trade Protective Coatings T-Wash is an etching wash for new bright unweathered, untreated galvanised surfaces. It creates a chemical reaction and causes the surface to turn black, which confirms that the surface has been degreased and etched. Treated surfaces are then ready for priming.
