Hydro-Defend® Concrete Waterproofer
H&C® HYDRO-DEFEND® Concrete Waterproofer is a premium quality water-based sealer that penetrates and protects aged, dry, porous surfaces. Because it penetrates, it resists water damage long after the water beading is gone. The durable, no sheen, acrylic formula can be used for both interior and exterior applications. This product is milky white when applied to ensure complete coverage, but dries to a clear, transparent coating.
