This advanced waterproofing and protective coating system is designed for application over bitumen, concrete, and ceramic tile substrates, combining a low-viscosity polyurethane primer with a high-performance polyurea membrane to deliver exceptional durability and protection. The primer ensures strong adhesion to both porous and non-porous surfaces, enhancing interlayer bonding and system integrity. 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 variations, and chemicals, it provides reliable long-term waterproofing for roofs, terraces, and exposed areas under demanding conditions. The system is completed with a two-component aliphatic polyurethane topcoat, providing a durable, non-yellowing protective finish with excellent resistance to UV exposure, chemicals, abrasion, and impact. It ensures long-term performance, easy maintenance, and a high-quality aesthetic finish for demanding surface applications.
