This paintable sealant is permanently flexible without cracking or hardening and adheres firmly to wood, metal studs, concrete, gypsum board, and other building materials while achieving and maintaining the specific STC (Sound Transmission Class) values and meeting LEED requirements.

Use it for exposed and unexposed applications at perimeter joints, floor and ceiling runners, cutouts in gypsum board, veneer plaster systems and other areas where a sound rated assembly is required. It can also be applied or buttered around all electrical boxes and outlets, cold air returns, heating and air conditioning ducts and other equipment penetrating wall surfaces for increased acoustical performance.
