Application

All the surface to he coated should be fully cured, duly and free from demolding oil, or curing membranes. The surface should be perfectly dry before coating with RAK Siloxane. RAK Siloxane is applied with either a low-pressure spray or brush. Stir the material well before use. Do not dilute with water or solvents. On vertical surfaces, RAK Siloxane should be flooded on, starting at the bottom, working steadily upwards. When used as protective impregnation, apply two coats as a minimum. Apply a second coat immediately after applying the first, ensuring the first coat does not dry, i.e. wet on wet.
