Single-Component Air Barrier

Sto RapidGuard is a single-component, multiuse air barrier and waterproofing material that seals rough openings, sheathing joints, penetrations, and transitions in above-grade wall construction. Applied with a caulking gun, the liquid-applied barrier adheres to damp substrates; installs between 33°F and 100°F; requires no tape, mesh, or fabric; and bridges cracks and seams in wall construction without tearing established barriers, according to Sto. RapidGuard is compatible with most building materials. stocorp.com
