How to use Mordant Pre Treatment Etching Wash

• Apply Mordant Pre Treatment Etching Wash & allow to turn black.  Once this has happened, wash with clean water.  This is usually after it is fully dried.  Any areas that havent turned black, (usually due to surface contamination) should be abraded using a suitable abrasive paper, then re-apply, however avoid over application as any pooling may result in the formation of fine brown deposits of copper.  After rinsing with clean water and allowing to dry before priming.

• Very Important  Once the pre-treated Mordant Pre Treatment Etching Wash surface has dried, it should be over painted with the appropriate metal primer within 48 hours or contamination may occur, affecting the end result. 

• Mordant Pre Treatment Etching Wash should be stored between 5 -25 degrees C and when not in use, cans should be kept sealed.  For guidance, Mordant Pre Treatment Etching Wash has a 12 month shelf life from the delivery date in their original containers.
