Cold applied roof deck coating system with separate, manually applied waterproofing membrane and with enhanced crack bridging properties (class B 4.2) and lVT+V (-20°C) for existing roofs exposed to light pedestrian traffic. Can be installed with a UV protective coating to avoid discoloring from the sun.
A weatherproof very flexible and durable roof deck coating system with 2 separate layers of membrane and a fiber reinforced fleece with enhanced crack bridging properties. Due to the excellent bonding properties of the PU binder, the system is an excellent solution for the renovation of older bituminiuos roofs. If required the membrane can be protected with a UV resistant topcoat to avoid discoloring from the sun.
