LRB Catalyst - 1 Quart

The Concrete Protector's LRB Catalyst is an essential additive designed to accelerate the cure time of Liquid Rubber Base (LRB) waterproofing membrane. When TAV (Thickening Activator) is not being added to LRB, the catalyst must be used to ensure proper curing. Simply add 0.5 oz of catalyst per gallon of LRB to achieve faster tack-free and foot traffic times. The catalyst allows LRB to cure to a tough, permanently flexible membrane in 4-6 hours at 70°F or higher.
