Acoustic Sealant is a one-part flexible acrylic water based acoustic mastic. It has been specifically formulated to form an acoustic and fire rated intumescent barrier by sealing gaps between plasterboard walls, floors and ceilings, dry linings, and lined insulation boards. Our acoustic sealant adheres to all construction substrates. It is emulsion acrylic based and gives a firm yet flexible seal to joints in a variety of fire rated structures. It will not support combustion and when subjected to heat, chars and intumesces preventing the spread of smoke and fire through the joint. Use it for internal perimeter pointing of fire rated door and window frames. Also available in Brown
