Laticrete’s Masonry Veneer Installation System (MVIS) Water Crack Isolation (WCI) enhances longevity of the building assembly when used with air-barrier systems, according to the manufacturer. The single-component, fluid-applied, bulk-water-management membrane is load bearing and nonflammable, and produces a monolithic elastomeric coating that bonds directly to concrete and cement-backer-board substrates. MVIS WCI is available in 5-gallon pails. Pricing varies by distributor and job scale.
