Surface Preparation
Surfaces must be clean, dry and sufficiently porous to allow the Watco Rainshield to penetrate. Remove all surface growths by wire brushing. Seal any cracks or joints. Do not use detergents to prepare the surface.
Application
Always test a small area first and allow to cure. Apply by brush. The surface should be well flooded to give at least 15cm run down of Watco Rainshield. If a second application is required allow 36 hours to lapse before applying the second coat.
