The need for a long-lasting, seamless, liquid applied, waterproof membrane, designed specifically for flat roof restoration has lead to the development and exhaustive testing of Dura 500 Liquid Applied, Roof Membrane. Based on thermoplastic technology, the product addresses issues of damage caused by water ponding, heat stress, and delamination that are associated with many coating systems in flat roof applications. Accelerated weather testing has demonstrated that Dura 500 is capable of  an effective service life exceeding 20 years in all climates and weather conditions including: intense heat, ponding water, hail impact and ice build-up.
