Surfaces must be clean, dry, sound and free of dirt, greases, soap, and other contaminants. Salting or
efflorescence, mould and mildew must be removed. Our WaterTite Waterproofing paint can be used over previously painted, non-glossy surfaces; however its waterproofing ability is then dependent upon the integrity of the previous coating. For best results, remove as much of the old coating as possible by manually scraping the surface, followed by thorough wire rushing. Exterior surfaces should be power washed or abrasive blasted to remove all loose and scaling paint and cement.
All holes and cracks, especially active water leaks, must be patched with WaterTite Polyurethane Sealant or a similar product. Follow manufacturer’s directions for dry time, etc.
Use in a well ventilated area. Extinguish all pilot lights and other sources of flames or ignition. Remove electrical equipment from the area. Stir or mix thoroughly before and during application. DO NOT THIN. Apply only when air, material, and surface temperatures are between 10-32ºC (50-90ºF) and the relative humidity is or less than 85%. Liberally apply the first coat using a thick polyester bristle brush, or by rolling a small section (91 cm x 91 cm (3x3 foot)) and then using a brush to work the coating into the pores of the masonry. Apply as much paint as necessary to produce a continuous, pinhole free film. Use a 25 mm (1”) nap roller cover for unpainted, porous surfaces or a 20 mm (¾”) nap roller cover for smooth or previously painted surfaces. The
second coat can be brushed or rolled.
