Zinsser WaterTite Clear Mold and Mildew Proof Waterproofing Paint from Rust-Oleum is a new clear coating that resists water pressure and protects against mold and mildew. This water-resistant paint forms an impermeable, smooth, non-pigmented barrier to water on bare masonry wall and floor surfaces. It can be used on interior or exterior, vertical or horizontal, concrete block and cast-in-place concrete. Backed by a five-year guarantee, the clear coating stops moisture from entering and exiting concrete surfaces.
