for foundationfor floorjoint

Product overview
Pure polyurea membrane, completely solvent-free, formulated for special waterproofing applications. Applied with hot spray equipment, it cures ultra-fast to form a continuous thermoset elastomeric membrane (capable of being both hard and flexible) with high mechanical and chemical resistance and long-term exterior durability. The membrane typically allows the system to be ready for service within hours.
