WATERTITETM Mold & Mildew-ProofTM* Waterproofing Paint is a revolutionary advance in sealing basements and masonry surfaces – a sealer guaranteed to keep water out and keep mold and mildew away for a minimum of five years. WATERTITE has a unique oil-base formula that combines a state-of-the-art waterproofing resin with Portland cement to create a coating that stops up to 34lbs psi of water pressure. It also contains a mildewcide to prevent the growth of mold and mildew for a minimum of five years after application, making it great for basements and other masonry surfaces where mold and mildew can be problematic. Unlike other waterproofers, WATERTITE can be applied to dry, damp or wet surfaces, so water problems can be cured immediately. It can be recoated in just four hours and dries to a smooth, bright white, non-yellowing finish that resists dirt and dust pick-up, unlike other waterproofers, which contain sand that can attract surface dust and dirt and promote mildew growth. WATERTITE can be tinted to most off-white or pastel colors. WATERTITE features an ultra low odor formula that has even less odor than latex paint. It adheres to any interior or exterior masonry surface, above and below grade and is formulated to prevent recurring efflorescence on concrete and cinder block. *WATERTITE contains a mildewcide to prevent the growth of mold and mildew on the paint film only.

Previously Painted Surfaces-It 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. A belt sander
with a 50 grit sanding belt is also effective. Exterior
surfaces should be power washed or abrasive blasted to
remove all loose and scaling paint and cement.

If you scrape, sand or remove old paint, you
may release lead dust. LEAD IS TOXIC. EXPOSURE TO

first coat using a thick polyester bristle brush, or by rolling
a small section (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 1” nap roller cover for unpainted, porous
surfaces or a ¾” nap roller cover for smooth or previously
painted surfaces. The second coat can be brushed or
