Improved Underlayments

ProSpec's line of Level Set underlayments now includes Expansion Stabilization Technology (EST), an additive that can help reduce shrinkage and cracking. EST works by controlling physical and chemical reactions during the plastic stage, when most shrinkage occurs. The new additive works with ProSpec's Rapid Cure Technology (RCT), which offers early strength development and fast curing, as well as less shrinkage post-curing. ProSpec. 800-738-1621.
