DRYLOK Fast Plug 00917 is a high-performance, fast-setting hydraulic cement engineered to instantly stop active water leaks through cracks and holes in masonry and concrete surfaces. This professional-grade formula sets in just 3 to 5 minutes, even under hydrostatic pressure, making it an essential solution for sealing floor-to-wall joints and patching settlement cracks. It expands as it cures to create a permanent, watertight seal and provides exceptional strength for anchoring metal fixtures to masonry. Suitable for both interior and exterior applications, this non-shrink compound requires no top-coat and helps reduce radon gas penetration in basement structures.
