A high quality water-borne acrylic intumescent building sealant. It cures to form a tough, tack-free seal with excellent adhesion to a wide variety of building surfaces. In the event of a fire, it will swell (intumesce) to form an insulating char, which is fire resistant and will resist the passage of smoke and flames.
Suitable for sealing expansion, contraction and construction joints where compartmentation and movement are factors; as a bedding/sealing compound for locating fire resistant board systems; to seal gaps which occur between fire-rated building components and the surrounding structures, for example, window and door frames; and as service penetration seal system for both cables and pipes.
