HYPERDESMO®-CLASSIC is a simple and economic solution for liquid polyurethane waterproofing and protection. It is a one component, of low viscosity, polyurethane fluid which cures with the humidity in the atmosphere to produce a highly elastic watrproofing membrane with strong adhesion to many types of surfaces. It is based on pure elastomeric hydrophobic polyurethane resin plus special inorganic fillers, which result in excellent mechanical, chemical, thermal, UV and natural element resistance properties.
