SEIRE WP 400 Pure polyurea waterproofing membrane for universal use

SEIRE 400 WP is a hot-applied, highly elastic 100% pure polyurea waterproofing membrane, with a high level of resistance against wear and chemicals. Once dry, it forms a continuous waterproof membrane, without joints or need for overlap or reinforcement (only singular points that join other construction elements are reinforced). It provides permanent elasticity, even at very low temperatures, and is able to absorb substrate movements. Its rapid polymerization means it can adapt to any surface and attain waterproofing properties within three hours (optimum conditions of use are achieved in 24 hours).
