Surface Preparation


To get the best results, ensure surfaces to be painted are sound, clean and dry (new surfaces particularly must be fully dry) and free from all defective or poorly adhering material such as dirt, grease and wax. Degrease where necessary with a suitable oil and grease remover. Rinse with clean water to remove residues.


Application Information


Apply a liberal coat of Mordant Solution by brush and allow to dry. If the surface fails to turn black overall, the most likely cause is contamination of the surface or the presence of a factory applied pretreatment. Rinse the surface thoroughly and abrade, using a suitable abrasive paper. Remove all residues and re-apply, Avoid over-application as pooling of the wash will result in the formation of a fine brown deposit of copper. After treatment the surface must be rinsed with clean water to remove all residues and then allowed to dry before priming. The pre-treated surface should be over coated with an appropriate metal primer within 48 hours or before contamination can recur.
