DRYLOK Fast Plug 00917 is a high-performance, fast-setting hydraulic cement designed to stop active water flow through cracks and holes in masonry surfaces. This professional-grade compound sets in just 3 to 5 minutes, even under constant hydrostatic pressure, making it an essential solution for emergency basement and foundation repairs. The unique formula expands as it cures, creating a permanent, watertight seal that locks into the substrate. It is suitable for both interior and exterior applications, including sealing floor-to-wall joints, patching swimming pools, and anchoring metal fixtures to concrete. This gray powder requires only a simple water mix and can be painted once fully set without the need for a specialized top-coat.
