Zinsser WaterTite LX Ultra Mold & Mildew Proof Waterproofing Paint is a modified acrylic copolymer coating formulated to create a water-tight barrier on concrete and masonry surfaces. It is suitable for interior or exterior use, above or below grade, on vertical or horizontal concrete block (excluding lightweight block) and cast-in-place concrete. The coating prevents moisture intrusion on basement walls, retaining structures, planters, and utility areas, and can also stop water from exiting canals or holding basins. It functions as a block filler in wet environments where epoxy finishes will be applied and is not recommended for swimming pools or areas in contact with potable water.Â
