Zinsser WaterTite Clear Waterproofing Paint protects concrete and masonry while preserving the appearance of the surface with a smooth, clear gloss finish. This low-odor, water-based acrylic coating is suitable for interior and exterior basement walls, masonry floors, retaining walls and concrete subfloors. A properly applied coating system resists up to 10 PSI of water pressure, and a mildewcide helps prevent mold and mildew growth on the paint film only. Apply at least two coats, brushing the first coat into surface pores for maximum waterproofing performance. This 1-gallon container covers up to 100 square feet per coat, depending on porosity and application. It dries to the touch in about 2 hours and can be recoated in 2–3 hours under recommended conditions. Compatible latex, oil-based or epoxy coatings may be applied over it. Clean tools with soap and water. Not recommended for garage floors, vehicle traffic, swimming pools or contact with drinking water.
