APPLICATION: Shake well before using. Rubber gloves and safety glasses are recommended when applying this product. Test this product on a small surface to verify the resulting gloss. NEW SURFACES: Verify that the surface is properly dried. The Low Gloss Sealer can be applied to surfaces forty-eight hours after the grout has been applied. Apply 2 - 3 coats using a clean sponge, brush or paint applicator. Let dry for 30-60 minutes between coats. EXISTING SURFACES: The surface must be clean, dry and free of wax, oil, silicone sealers or other resides. Use Surf-Pro Intelligent Cleaner to remove these contaminates. Test the surface by spraying water on the surface. If the water beads then you still have sealer on the surface. Clean again with Surf-Pro's Intelligent Cleaner. PRE-GROUTING: Apply a coat of Low Gloss Sealer two hours prior to grouting. This will prevent the grout from adhering to the stone.
