Tremstop Acrylic Spray: 5G Pail Firestop


TREMstop Acrylic SP is an all-purpose sealant that can accept paint once fully cured. The spray application method provides significant labor savings over a gun-grade sealant, particularly on long joint runs. It features excellent movement and superb unprimed adhesion to a wide range of substrates. When installed in accordance with a tested firestop system, it affords code compliance for both through-penetrations and fire-rated joints.  It also provides a fast and easy solution for restoring the STC rating of a sound-rated assembly.
