In this video, we demonstrate Belzona 3121 - a 2-part polymer composite designed to provide emergency roof repair and weatherproofing for leaking roof areas. Belzona 3121 (MR7) is liquid-applied and bonds strongly to all common roofing surfaces including slate roofs, tile roofs, asphalt, felt, asbestos cement sheet roofs and metal roofs, even during adverse weather conditions. This fast-curing, all climate flexible repair system incorporates a reinforcement sheet which ensures the coating will adapt to roof movements and follows complex roofing contours. This system is water resistant immediately after application and can cure even if fully immersed in water.
