This advanced waterproofing and protective coating system is specifically designed for application over bituminous membranes, combining a low-viscosity polyurethane primer with a high-performance polyurea membrane to deliver exceptional durability and protection. The primer ensures strong adhesion to aged or new bitumen surfaces, enhancing interlayer bonding and overall system performance. The polyurea membrane, a fast-curing, cold-applied liquid, forms a seamless, highly elastic waterproofing layer with up to 1000% elongation and excellent crack-bridging capability. Resistant to UV exposure, temperature fluctuations, and chemicals, the system is ideal for upgrading and protecting bitumen roofs, terraces, and exposed surfaces, ensuring long-term waterproofing and durability in demanding conditions.
