New Vapor-Open Liquid WRB

Kemper System America’s Wall Guardian FW-100A is a liquid-applied fibered acrylic air barrier that reportedly acts as a vapor-open (17.3 perms) water and weather barrier. The water-based, low-VOC material is designed to resist air and water infiltration and to bond to a range of wall materials, including extruded polystyrene, CMU and brick masonry, and concrete. Applied in a single coat with a heavy-duty sprayer, roller, or brush, the barrier offers unified substrate protection, even on curved or other unconventionally shaped walls. stscoatings.com/our-products/wall-guardian/
