PROOF 668 is a single-component acrylic waterproofing coating that cures to form a seamless, continuous membrane. It is enhanced with advanced UV-resistant and anti-aging additives, ensuring excellent durability under prolonged weather exposure. Once cured, it forms a highly elastic waterproofing layer with strong crack-bridging capability and long-term performance stability. The coating protects concrete and masonry against water ingress, minimizing deterioration caused by wet–dry cycles and UV radiation. With superior UV resistance, PROOF 668 is suitable for exposed applications without additional protective coatings, while maintaining long-lasting color and performance.
