Expandable Polyurea is a hot polyurea system that can be applied with a special spray machine that can reach 4-5 times its own volume. It is a special product developed for a seamless waterproofing, thermal insulation, protection and sealing. It provides a smooth surface by filling the height differences on rough (void, protrusion) surfaces. Ideal for surfaces such as concrete, wood, asphalt, fabric and sheet metal. No primer required. It is a two component, solvent free, UV resistant, 100% pure product. As a result of the reaction, a membrane with mechanical and chemical resistance properties is formed on the applied surface. Thanks to these features, it can be easily used on all kinds of surfaces for waterproofing and coating purposes
