Quick Cure Waterproofing Membrane The unique formulation of Watchdog® Quick Cure 90 allows the membrane to cure up to 90% faster than the traditional Watchdog Waterproofing membranes, while maintaining 3 ft hydrostatic head resistance. Watchdog Quick Cure 90 has the exceptional ability to hang on poured concrete and parged block walls to easily build targeted thickness. Tight construction schedules and inclement weather are no match for the set up and cure times of Watchdog Quick Cure 90.
