Clear and sweep the area to be etched to remove debris. Ensure the surface is free of oil and grease before application.
Dilution Guide: Mix 1 part Coo-Var Acid Etch with 3 parts water, further applications may be necessary depending upon the severity of etch / cleaning required.
When Acid Etch is applied it begins to react to reach with the surface and will bubble as the reaction is carried out. When the bubbling has stopped then the reaction is complete and the remaining neutralised acid should be washed away with freshwater.
Allow to dry completely before attempting to paint the surface.
