Firestop Coatings and Compounds

Nelson Firestop FSC™ cable coating and FSC3™ joint coating are water based, fire protective coatings designed for labor saving spray applications. FSC cable coating is sprayed or brushed onto continuous runs of electrical power, communications and control cables to prevent propagation of fire. FSC3 joint coating is sprayed, brushed or toweled over mineral wool insulation packed within construction joints to provide a fire protective coating.

Nelson Firestop Compound (CMP™) is a cementitious material that is mixed with water and applied to penetrations and openings to provide a weather resistant, non-shrinking fire-rated seal. It is similar in appearance to mortar and can be troweled to a smooth finish.
