Duramax is a single component, liquid membrane designed for cold application to flat roofing. This high performance liquid finish cures to form a tough and seamless waterproof membrane, which offers a strong, durable and weather-proof protection when applied to any flat roofing system.

Duramax is recommended for use on flat roof overlay systems and can be used on traditional built up roofing, in both new constructions and refurbishment projects. It is ideal for balconies, terraces and podium decks and as a detailing product for other roofing systems, including asphalt, bituminous felt, concrete, single ply and metal surfaces.
