Grabber® Acoustical Sealant is a one-part, non-flammable, latex base product designed specially for the reduction of sound transmission in all types of wall partition systems. The sealant's primary function is to achieve and maintain the specific STC (Sound Transmission Class) value of the system designed. Grabber® Acoustical Sealant remains permanently flexible and adheres firmly to wood or metal studs, concrete, gypsum board and most other types of building substrates. The product formulation is non-hardening, non-staining and non-migrating. It maintains a tough rubber-like seal against air-borne sound, air infiltration and moisture, and offers fast, smooth, easy application without difficulty in extrusion. Clean up is quick and easy with soap and water. Grabber® Acoustical Sealant should be used where an effective means of reducing sound transmission is required.
