StopGap™ Sealant is a highly elastic, water-based sealant used for reducing sound transmission at the perimeter of wall systems, or around electrical box cutouts to achieve specified STC/MTC values. The surface dries to a tough film, but the sealant remains flexible and stays pliable for up to 5 times longer than alternative brands. Unlike other products, StopGap™ has no residual run-off. StopGap™ is paintable (dries white) and non-staining, and meets ASTM E-84 standards for flame retardancy. StopGap™ comes in a large, 28 oz. caulking tube and therefore requires a larger than normal-sized caulking gun, which can be purchased at any local hardware store. This product does not qualify for free shipping. Details: Auralex® StopGap™ will achieve a Sound Transmission Class (STC) of 53 when applying it in accordance with ASTM C-919 “Standard Practice for use of Sealants in Acoustical Applications”. To achieve the 53 STC, StopGap™ should be applied as two beads of sealant at the top, bottom
