StopGap acoustical sealant is highly elastic water-based sealant that reduces sound transmission at the perimeter of wall systems or around electrical box cutouts to achieve specified STC/MTC values. StopGap's surface dries to tough film but the sealant remains flexible and stays pliable for up to five times longer than alternative brands. And unlike other products StopGap has no residual run-off. StopGap is paintable and nonstaining and meets ASTM C-834 standards for flame retardancy.
StopGap comes in a large, 29oz caulking tube and therefore requires a larger than normal caulking gun which can be purchased at any local hardware store. Coverage per 29oz. cartridge is approximately 89ft. with a 3/8 inch bead applied.
