Providing a minimum compressive strength of 5,000 psi (after 28 days of drying time), USG Durock™ UltraCap self-leveling underlayment is mixed with water at the job site to yield a smooth and monolithic surface of up to 2 in. thick (deep fi lls up to 5 in.).
A 1/4 in. thick underlayment weighs approximately 2.6 lbs./sq. ft. and has an approximate dry density of 125 lbs./cu. ft. Floor covering can be installed in two to three days, depending on underlayment thickness and drying conditions.
Portland cement-based poured underlayment
- Ideal over concrete and wood subfloors
- Fast application and fast setting allow for quick return of normal trade traffic
