CCW-703 Liquiseal liquid-applied waterproofing membrane is a two-component polyurethane waterproofing system. It is self-curing, forming a seamless, impermeable coating that bonds tightly to an appropriate substrate, preventing the lateral transfer of water. Liquiseal is easily mixed at the jobsite and applied using a squeegee, trowel, or spray equipment, providing a waterproof rubber membrane.
