Application

Nelson FSP™requires no special skills or tools to install. To ensure adequate adhesion, all surfaces should be clean and free of dust, grease, oil, loose materials, rust or other substances. Apply the required depth of FSP™over various backing materials as required. Ensure that the FSP™makes complete contact with the inside surface of the opening and also the surface of each penetrating item. FSP™is ideal for cable penetrations where cable additions are common due to the characteristic of FSP™remaining pliable. It can also be used for metallic, non-metallic and insulated pipes, cable tray and ductwork applications in a variety of fire rated floor or wall constructions. Actual installation may vary according to the type of firestop application. Refer to available firestop systems.
