WIDOPUR 1K is a one-component liquid waterproofing system on a PUR base for flat roofs and similar structural components, and for all types of connections and detail work. WIDOPUR 1K has as its material base polyurethane prepolymer. The material can be applied ready-to-use straight from the container– no mixing or preparation necessary. Reinforcement is provided by the encapsulation of a polyester mesh fabric (G165), which is also used for connections and detail work.
