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 deliveres compressive strengths between 2,000 psi and 3,200 psi, enhanced resistance to surface abrasion, and faster dryiing time. Its shrink crack-resistant surface provides a perfect base for practically any floor covering.
