Recommended For

SC175 is developed primarily for commercial construction utilizing light weight cavity walls and floor systems.  Used successfully in office buildings, hotels, apartment complexes and other types of commercial and residential construction; exposed and unexposed applications at perimeter joints, floor and ceiling runners, cutouts in gypsum board, veneer plaster systems and other areas where a sound rating assembly is required.  Can be applied or buttered around all electrical boxes and outlets, cold air returns, heating and air conditioning ducts and other utility equipment penetrating wall surfaces for increased acoustical performance.  Works well for sealing sill and base plates in residential construction.

For Best Results

Do not use in underwater applications or permanent water immersion; applications requiring temperature resistance greater than 170°F (77°C) use on mirrors and metals that will corrode.  One surface must be porous, not for use with two non-porous surfaces.  Not recommended for polyethylene, polypropylene, polytetrafluoroethylene (PTFE)/Teflon, nylon, or cement board (Durock).
