CCW 703-V 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. CCW 703-V Liquiseal is easily mixed at the jobsite and applied using a squeegee, trowel, or spray equipment, providing a waterproof rubber membrane. Liquiseal is available in two viscosities (H & V) for application to Horizontal and Vertical surfaces. Typical applications are between structural slab and wearing course on parking garages, plaza decks, balconies, roof decks, terraces, mechanical equipment rooms, fountains, kitchens, wetrooms, malls and shower stalls. Liquiseal is ideally suited for waterproofing on below-grade foundation walls, tunnels, planters and other areas where a seamless, elastomeric waterproofing is required. Questions? Contact Us.
Use Vertical Grade Liquiseal for coating walls, vent pipes, air ducts, or other vertical surfaces. Trowel-applied Vertical Grade Liquiseal will not sag or slide down the walls so proper thickness is maintained top to bottom.
Application of Liquiseal Waterproofing Membrane shall not commence unless the temperature is 40°F and rising, or if the weather is inclement or threatening. Should the uncured Liquiseal Waterproofing Membrane be exposed to rain prior to obtaining a surface cure, the water will penetrate the surface of the membrane and form craters. If this occurs, allow the waterproofing membrane to cure and dry thoroughly. Remove all dust and dirt and apply a top coating of Liquiseal Waterproofing Membrane to fill all depressions in the membrane.
Combine the two components of Liquiseal according to mixing instructions. When mixing Part A and Part B, use a variable-speed ½” drill with a Model PS Jiffy blade for a minimum of 5 minutes. The mixed batch will provide a pot life of 1-2 hours at 40°F to 60°F and ½ to 1 hour at 80°F. As soon as Liquiseal Waterproofing Membrane is mixed, apply directly to the concrete slab in a uniform application spreading with a squeegee or trowel. Controlled coverage is obtained by applying 4 gallons of Liquiseal per measured 100 sq. ft., resulting in a seamless membrane approximately .055″ +/- .005″ thick. All fluid-applied product application rates are based on theoretical coverage relative to the percentage of solids in the material. These are minimum application rates to achieve the required dry film thickness for the system and do not account for substrate condition or porosity.
