It contains addition of cross-linking polymers, special glass micro fibres, pigments and advanced antifungal additive that provides long lasting tough waterproofing membrane. The high solar reflective index of the membrane provides a heat reflective surface, minimizes surface temperature of the membrane and reduces heat ingress keeping the interior of the building cooler and thereby increasing thermal efficiency of the building. The Product provides a seamless, smooth waterproof finish which is resistant to UV exposure and has elastic properties.
