A general purpose, asbestos-free formulation for wet-weather repair of roof leaks, this product has unique water displacing characteristics, which ensure superior bonding to both wet and dry substrates and surfaces. The heavy, “trowel-grade" consistency makes this product ideal for flashing details and a variety of roofing and waterproofing repairs such as moving joints and roof penetrations where its flexibility and elasticity make it superior to standard plastic cements. It contains a special additive that actually displaces water from wet surfaces to create a tight seal and its easy application makes it excellent for low-temperature flexibility.
