This advanced waterproofing and protective coating system combines a low-viscosity polyurethane primer and a high-performance polyurea membrane to provide exceptional durability and protection for a variety of surfaces. The primer penetrates deeply into porous and non-porous substrates, ensuring excellent adhesion and enhancing the performance of the waterproofing layer. The polyurea membrane, a fast-curing, cold-applied liquid, forms a seamless, highly elastic, and durable waterproofing layer with 1000% elongation and outstanding crack-bridging capabilities. Resistant to extreme temperatures (-40°C to +90°C), UV exposure, and chemicals, this system is ideal for walkable roofs, terraces, balconies, kitchens, bathrooms, and cementitious or metallic surfaces, ensuring long-lasting waterproofing and protection in both industrial and residential applications.
