Worry no more about water infiltrating your basement walls. Zinsser Watertite Mold & Mildew-Proof Waterproofing Paint 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 34 lbs psi of water pressure, twice the strength of latex waterproofers. 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. This smooth, non-gritty finish applies easily to wet or dry walls and the ultra low odor oil-base formula has even less odor than latex paint. This 3.7L can covers 7m² (75 sq. ft.) of porous surface on the first coat, 9.3m² (100 sq. ft.) on the second coat.
