PUA 680 is a next-generation hybrid PU–Acrylic waterproofing system, engineered to combine the superior performance of polyurethane and acrylic, delivering exceptional elasticity, long-term durability, and excellent adaptability to tropical climates. Once cured, the product forms a seamless, joint-free waterproofing membrane capable of bridging large cracks (up to ≥10 mm) while maintaining stability under extreme temperature, weather, and environmental conditions. Advanced UV-resistant and anti-aging additives ensure long-lasting mechanical performance and color stability in exposed applications. PUA 680 not only effectively prevents the ingress of water and moisture but also protects concrete surfaces against aggressive agents such as chloride ions, sulphates, and marine environments, making it suitable for both residential and industrial projects with high durability requirements. With excellent adhesion to a wide range of substrates (concrete, metal roofs, existing tiles, and existing waterproofing layers), and versatile application on both vertical and horizontal surfaces, PUA 680 is a multi-purpose waterproofing solution ideal for exposed areas subjected to severe weather conditions
