ProSpec has introduced Expansion Stabilization Technology for its line of Level Set underlayments and wear toppings, providing added protection against shrinkage and cracking. EST is an additive designed to reduce the potential for cracking and shrinkage through controlling precure chemical and physical reactions during underlayments’ plastic stage, when up to 80 percent of shrinkage occurs. EST works in conjunction with ProSpec’s Rapid Cure Technology, which was introduced earlier this year. ? (800) 738-1621 ? www.prospec.com
