Zinsser Hydraulic Cement

Zinsser WaterTite Hydraulic Cement is a powerful solution for stopping active water leaks and sealing deep cracks in concrete and masonry. Designed for both interior and exterior use, this fast-setting cement expands as it cures, forming a watertight seal in just five minutes—even on wet surfaces. It’s ideal for patching basement floors, cellar walls, retaining walls, planters, fountains, and other moisture-prone areas. WaterTite can also be used as an anchoring cement, making it a versatile choice for structural repairs. The application is straightforward: mix two parts cement to one part water, stir until it forms a putty-like paste, and press it firmly into the crack or hole. The compound begins to set within 3–5 minutes, so only mix what you can apply immediately. Once in place, it quickly hardens to block water intrusion and reinforce the surface. WaterTite is compatible with a wide range of substrates including concrete block, cast-in-place concrete, stucco, exposed aggregate, and slump block. It’s an excellent choice for homeowners, contractors, and maintenance teams looking for a reliable, easy-to-use product that delivers fast results. With its high solids content and no volatile organic compounds, WaterTite offers a durable and environmentally conscious option for sealing and patching concrete and masonry surfaces.
