All Purpose Waterproof Sealant

When it comes to selecting a tough high-performance, sealant, the choice is clear. Ultra Clear™ Flexible All Purpose Waterproof Sealant from DAP® outperforms the competition with its superior flexibility that won’t crack and clearer-than-silicone finish that stays crystal clear.


Developed for a range of interior and exterior projects, Ultra Clear stays permanently flexible, even in cold weather, providing a 100% waterproof and weatherproof seal to keep out water, air and moisture for years without cracking or breaking down. It has strong adhesion to a variety of building materials such as wood, glass, metal, tile, brick and stone, without tearing or pulling away. It can even be applied in low temperatures (20°F) and on wet surfaces to stop leaks instantly and save time.


Unlike silicone, Ultra Clear applies crystal clear and stays crystal clear with no hazing or yellowing over time. Once cured, it’s also mold and mildew resistant, which combined with the crystal clear clarity, results in a seamless blend with the surface and a better finished appearance.


Ultra Clear is available in a 10.1 fl. oz. cartridge and 5 fl. oz. squeeze tube. The easy-to-use 5.0 fl. oz. squeeze tube eliminates the need for a caulk gun and is ideal for smaller jobs, getting into tight spaces or when working on a ladder. Ultra Clear is easy to apply, paintable and water-ready immediately for quicker resistance to water damage and wash-out.
