DRYPROOF is a ready-to-use MASONRY WATERPROOFER formulated for waterproofing interior, exterior, above or below grade masonary surfaces. No pre-wetting necessary. Do not use on floors. This tough, alkali and mildew resistant coating may be applied on uncured concrete and on slightly damp masonry, but best results are obtained when applied to dry surfaces.
SURFACE PREPARATION: Masonry surfaces must be clean from dirt, dust, grease, oil, frost or paint. Patch holes or cracks with hydraulic cement. Efflorescence, a white powdery, crystal-like deposit visible on the masonry surface, must be removed. CLEAN & FREE used according to manufacturer directions is an effective efflorescence removal agent.
APPLICATION: STIR THOROUGHLY. DO NOT THIN. DRYPROOF MASONRY WATERPROOFER may be applied by brush, roller or spray. For best waterproofing results, apply the first coat with a BRUSH working the WATERPROOFER into the pores of the masonry. Two coats are recommended over porous masonry surfaces. Paint only when air and surface temperatures are 5˚C or higher.
IMPORTANT: If excessive leaking is present apply the first coat to the lower ½ of the wall (area where most leaking occurs). Allow overnight drying before applying the next coat to the entire wall surface. If leaking is still visible these areas should be painted again when previous coat is thoroughly dry. When painting the inside surfaces of concrete sterns, fish ponds and water tanks, allow the paint to dry thoroughly before filling with water. Wait 48 hours, then drain and refill. Clean application tools with turpentine or mineral spirits immediately after use.
CAUTION: Avoid contact with the skin and eyes. Keep out of reach of children.
