KOSTER Elastic Roof is an elastic, crack bridging, and solvent-free waterproofing material for dry and slightly damp substrates. It is free of VOC’s (Volatile Organic Compounds), free of Polyurethanes, and free of Isocyanates. The fast drying foil-like coating is highly flexible, watertight and water vapor permeable. The foil is resistant against ageing, hydrolysis, UV-rays, frost and de-icing salts. The white color reflects heat. Since KOSTER Elastic Roof sticks to itself, the application is easy and seamless.
