Auralex StopGap Acoustical Sealant

Auralex StopGap Acoustical Sealant Auralex StopGap Acoustical Sealant Description: Auralex StopGap Acoustical Sealant is a 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 a tough film but the sealant remains flexible and stays pliable for up to 5 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, 29 oz caulking tube and therefore requires a larger than normal-sized caulking gun, which can be purchased at any local hardware store. Coverage per 29 oz. cartridge is approximately 40 linear feet with a 3/8 inch bead applied.
