|Remove any objects near your concrete basement walls. Clean the wall surface thoroughly to remove dirt, grease and other contaminants that can prevent the waterproofer from adhering properly.|
|Remove any efflorescence – a powdery white deposit found on many concrete surfaces – with WATERTITE™ Etch & Cleaner for Concrete and Masonry. Rinse the surface thoroughly with water. Allow excess water to evaporate.|
|Remove any mold and mildew with a solution of one cup bleach to one gallon water.|
|If the basement is already painted, remove as much of the existing paint as possible. Patch all holes and cracks, especially those that show signs of active water leaks, with WATERTITE™ Hydraulic Cement. To stop active and non-active water leaks, seal the joint where the floor and wall meet with WATERTITE™ Polyurethane Sealant.|
|Once the walls have been cleaned and cracks have been repaired, liberally apply the first coat of WATERTITE™ Mold and Mildew-Proof™* Waterproofing Paint using a thick synthetic brush, or a large nap roller, to a small section of the masonry. WATERTITE™, available in an oil-base and latex-base formula, is guaranteed to stop water and offers a five-year mold and mildew-proof paint film guarantee.|
|Using a brush, work the coating into the pores of the masonry to produce a continuous pinhole-free film.|
|Wait two to three hours before applying a second coat with a brush or roller. Allow to dry.|
Tip: WATERTITE™ can also be applied to concrete floors before installing carpeting, tile, linoleum and other flooring to prevent ground water from seeping through the floor and ruining your new flooring.
*WATERTITE™ contains a mildewcide to prevent growth of mold and mildew on the paint film only.
