Zinsser WaterTite Hydraulic Cement - Gray, 2.5 lb

Zinsser WaterTite Hydraulic Cement in Gray is a fast-setting repair material for stopping leaks and filling deep cracks and holes in concrete and masonry. It bonds to wet surfaces and expands as it sets to help create a watertight repair, making it useful for basement walls, concrete block, stucco, cast concrete and retaining walls. Suitable for interior and exterior repairs, it can also be used as an anchoring cement. Mix only the amount that can be applied within its approximately 3–5 minute working time; it sets to form a watertight repair in about 5 minutes, while full curing takes longer. This 2.5 lb carton is a convenient preparation product before applying a compatible masonry waterproofing coating. Prepare the repair area and mix with water according to the label for reliable adhesion and performance.
