Trusted for both interior and exterior waterproofing applications
Zinsser WaterTite 5L is a professional-grade, solvent-based waterproofing paint formulated for interior and exterior masonry surfaces. Designed to stop water ingress up to 34 psi, this advanced coating creates a durable, smooth, non-gritty finish that protects concrete, brickwork, and cementitious surfaces from damp, leaks, and recurring efflorescence. Its unique combination of waterproofing resin and Portland cement ensures a long-lasting barrier that adheres to dry, moist, or wet substrates, allowing immediate repair of water-affected areas without waiting for the surface to dry.
Unlike traditional waterproofers, WaterTite can be recoated in just four hours, offering a fast turnaround for domestic and commercial projects. The ultra-low odour formula is safe for use indoors and outdoors, providing a bright white, non-yellowing finish that resists dirt, dust, and staining. This product is ideal for basements, retaining walls, driveways, patios, and other masonry surfaces that require reliable, high-performance waterproofing.
