Zinsser WaterTite Damp Wall Primer - Bright White, 1 Quart

Zinsser WaterTite Damp Wall Primer in Bright White helps seal damp or dry concrete and masonry against moisture while preparing the surface for a protective finish. This oil-based primer is formulated with Portland cement to bond to properly prepared concrete block and cast-in-place concrete, helping prevent recurring efflorescence in basements, cellars and other moisture-prone areas. Suitable for interior and exterior use above or below grade, it can be applied to damp surfaces that are free of running water and active leaks. Apply at least two coats to create a continuous, pinhole-free coating for maximum hydrostatic pressure resistance. This 1-quart container dries to the touch in about 1 hour and can be recoated or topcoated after a minimum of 4 hours under recommended conditions. Clean tools with paint thinner or mineral spirits. Not intended as an exposed finish on surfaces receiving direct foot traffic.
