StopGap Acoustical 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. And unlike other products, Stop-Gap has no residual
run-off. StopGap is paintable and nonstaining, and meets ASTM C-834 standards
for flame retardancy.
Coverage per 29 oz. cartridge is approximately:
* 1/4 inch bead: 89 linear feet (27m)
* 3/8 inch bead: 40 linear feet (12m)
* 1/2 inch bead: 22 linear feet (6m)
