USG Levelrock
Concrete Floor Underlayment
USG's Specialty Products Division has added Levelrock brand Quik-Top Floor Underlayment to its family of Levelrock poured gypsum-concrete underlayments. This new self-leveling product dries within 15 hours, minimizing downtime during flooring installations.
Levelrock Quik-Top is ideal for repairing damaged or uneven flooring or for topping rough or spalled concrete. It can be applied over cement or gypsum concrete subfloors, creating a monolithic, high-strength (5,000 to 6,000 psi) surface that accepts a variety of floor coverings, including carpeting, ceramic tile, wood laminate, hardwood and vinyl. The underlayment can also function as an attractive decorative finished floor when used with an approved Valspar coating system.
Conventional poured concrete requires 20 days or more, while other gypsum-concrete underlayments need five to six days to dry. This product’s quicker drying time and high production rates allow for continued trade traffic within hours of installation. The fast drying time limits the potential for mold and mildew formation by covering the surface too early, and because the product formulation has less water than competing products, it introduces less moisture into the structure. Quik-Top also offers an extremely strong, economical, high-performance surface that won’t flake or powder.
