DRYLOK Fast Plug is a high-performance hydraulic cement designed to instantly stop active water leaks through cracks in concrete and masonry surfaces. This fast-setting compound expands as it cures, creating a permanent watertight seal that can withstand extreme hydrostatic pressure up to 1,500 PSI. It is suitable for both interior and exterior applications, including basements, swimming pools, retaining walls, and fountains. The powder formula sets in approximately 3 to 5 minutes, making it an essential solution for emergency repairs and sealing floor-to-wall joints. This 4 lb container provides a durable gray finish that can be painted over with masonry waterproofer once fully cured.
