Drylok 1 gal. White Masonry Waterproofer

Drylok Extreme Masonry Waterproofer is formulated with flexible encapsulated polymers that penetrate deep into masonry pores to provide exceptional waterproof protection. Ideal for interior, exterior, above-grade, and below-grade applications, this breathable latex-based coating helps prevent moisture buildup and reduces radon gas penetration without trapping moisture in masonry walls. Specially formulated with an environmentally friendly biocide to resist mildew growth on the dry paint film, it requires no pre-mixing or pre-wetting for convenient application. The smooth, low-odor formula complies with VOC requirements and cleans up easily with warm, soapy water, creating a durable finish that accepts latex decorative topcoats after drying.
