Wall-Lok exterior elastomeric wall coating for waterproofing also acts as a UV protective barrier. The coating protects from moisture intrusion, enhances curb appeal, and is said to extend the longevity of the exterior structure. For use across brick, concrete, masonry, and exterior-insulation finishing systems, the product forms a touch film on the surface of the building. The coating blocks formation of mold and mildew and prevents mortar from crumbling due to water penetration. It is available in a variety of colors including custom colors.
