Weatherseal XL

Waterproofing sealer providing excellent chemical and abrasion resistance.

Dex-O-Tex Weatherseal XL is a water-based, waterproofing sealer providing excellent chemical and abrasion resistance, including exposure to oil, grease, brake fluid, salt, calcium chloride, limited caustics, dilute acids, kerosene, and alcohol. Formulated for superior adhesion, Weatherseal XL bonds well to concrete, cement mortars, tile, Dex-O-Tex cementitious copolymer systems, and other substrates. It resists disbonding, blushing, whitening, or blistering caused by moisture vapor transmission and ultraviolet light exposure. Weatherseal XL is easy to clean, fully VOC compliant, and suitable for use on interior and exterior surfaces, such as automotive garages, driveways, patios, pool decks, loading docks, balconies, decks, and more.
