About this product
A 100% silicone liquid applied Air and Weather Barrier designed to protect against air infiltration and water penetration. The vapor permeable, one component, water based coating cures to form a flexible membrane that is impervious to water but has the ability to "breathe", allowing water vapor to escape from inside the substrate. The coating offers long-term protection from air and water infiltration; normal movement imposed by seasonal thermal contraction and expansion; ultraviolet radiation; and the elements. The coating maintains its water protection properties even when exposed to sunlight, rain, snow, or temperature extremes. There is not a limit on exposure time before being covered by the exterior cladding and can be applied between -6°C (20°F) and 38°C (100°F) to a clean, dry surface.
