CLK Silicone Sealant

Product From Nelson Firestop Products

Nelson Firestop’s CLK silicone sealant is intended for firestop penetrations and construction joints, such as areas around metallic pipes or conduits and for floor-to-wall, floor-to-floor and head-of-wall applications. The waterproof, smoke-proof and gas-proof sealant is installed with a caulking gun or manually using a mason’s trowel or putty knife. It is non-shrinking, non-toxic and has enough flexibility to allow for movement and vibration.
