Gyp-Crete 2000/3.2K Gypsum Floor Underlayment


With Gyp-Crete 2000/3.2K, we raised more than the compressive strength — we raised the bar on underlayment performance. Gyp-Crete 2000/3.2K delivers compressive strengths between 2,000 psi (13.8 MPa) and 3,200 psi (22.1 MPa), enhanced resistance to surface abrasion, and faster drying time. It’s ideal for use over wood subfloors in single family, light commercial and multifamily construction, as well as renovation projects. Its shrink crack-resistant surface provides a perfect base for practically any floor covering.

Gyp-Crete 2000/3.2K Gypsum Floor Underlayment

Gyp-Crete 2000/3.2K is poured to a minimum of 3/4" (19 mm) over wood. By varying the depth, your applicator can correct a floor that has sagged out of level, and compensate in areas requiring smooth transitions between floor coverings of different heights.

With application rates up to 40,000 square feet (3,716 m2) in a single day, Gyp-Crete 2000/3.2K can match the most ambitious construction schedule. Following application, it can be walked on within 90 minutes. And unlike lightweight concrete, Gyp-Crete 2000/3.2K won’t shrink crack.

Gyp-Crete 2000/3.2K is an eco-friendly building product and is GREENGUARD and GREENGUARD Gold Certifed.

Gyp-Crete 2000/3.2K also enhances sound control by:

  • Sealing perimeter cracks, preventing sound leaks from room to room
  • Stiffening the floor, virtually eliminating squeaky floors and nail pops
  • Muffling sound transmission, despite its light weight
Builders and owners alike appreciate Gyp-Crete 2000/3.2K because it won’t warp or delaminate like plywood. Its noncombustible gypsum content also enhances fire safety by slowing the spread of fire and helping prevent smoke leaks.
