What Is Polyurethane (PU) Coating?
Polyurethane (PU) coating is a liquid-applied waterproofing membrane made from polyurethane polymer compounds. When applied to a roof surface, it cures into a seamless, elastic, rubber-like layer that completely blocks water penetration.
PU coating is widely used in Pakistan for roof waterproofing, terrace protection, and basement sealing due to its flexibility, durability, and resistance to UV rays and extreme heat. Unlike traditional methods such as bitumen sheets or cement-based treatments, polyurethane coating forms a joint-free membrane with no seams or weak points, making it one of the most effective PU coating for waterproofing solutions for flat roofs.
