Drylok 00917 Hydraulic Waterproof Cement, 4-Pound, Gray

A fast-setting hydraulic cement, DRYLOK Fast Plug, sets in just 3 – 5 minutes, effectively stopping the flow of up to 3,050 lb. of water through cracks and holes in concrete and masonry structures. This powder, when mixed with water, can be used to patch interior or exterior mortar joints, cracks, and holes in masonry walls above or below grade, sealing leaks around concrete and masonry. The cement sets quickly, within 3-5 minutes, to stop active water leaks, even under pressure, and anchors metal to masonry. No top coat is required, and the cement expands as it dries to lock it in place. With a coverage of 16 cu. in./lb., this hydraulic cement is ideal for patching leaks in masonry wall joints and settlement cracks, and it can withstand up to 3,050 lb. of hydrostatic pressure. For clean-up, soap and water can be used.
