Dulux Trade Mordant Solution (also known as acid etch, T wash) chemically etches the surface of new, bright galvanised metal, to prepare them to improve the adhesion for subsequent paint systems. It is water based.

For best results, ensure surfaces are sound, clean and dry (new surfaces in particular must be fully dry) and free from any defective or poorly adhering material, dirt, grease or wax etc. Degrease where necessary with a suitable oil and grease remover. Rinse with clean water to remove residues. Apply a liberal coat of Dulux Trade Mordant Solution by brush and allow to dry. If the surface fails to turn black, the most likely cause is a contaminated surface or the presence of a factory applied pretreatment. Thoroughly rinse the surface and abrade. Remove all residues and re-apply Dulux Trade Mordant Solution. Avoid over-application which will result in the formation of a fine brown deposit of copper. After treatment the surface must be rinsed with clean water to remove residues and then allowed to dry before priming. The pre-treated surface should be overcoated with an appropriate Dulux Trade metal primer within 48 hours or before contamination can recur.

Clean all equipment with water immediately after use.
