LePage 1435208 Acoustical Sealant, Black, 41 to 95 deg F, 295 mL Cartridge

LePage PL acoustic-seal has a unique blend of synthetic rubber and polymers to bond polyethylene vapor barrier sheets. It provides an efficient seal to aid in the reduction of airborne sound transmission in wall assembly systems. PL acoustic-seal should only be used in concealed areas. Since this product does not dry, it is normal for the sealant to accumulate dirt, but this will not affect its functionality.
