Sure Klean® Weather Seal Color Enhancer WB is a long-lasting, penetrating water repellent that deepens and enriches the natural color of porous, stone, concrete and tile, including most clay, concrete and porous natural stone paving. The water-based blend of siloxane resins is ideal for enhancing the color intensity of new surfaces and reviving faded, weathered colors to better than new – inside or out. Treated surfaces also repel water, and the dirt, salt and contaminants water carries. Easy-to-apply Color Enhancer WB helps surfaces look better, last longer and clean up more easily. It will not trap water vapor within the substrate, alter the natural texture of treated surfaces or fade or “yellow” from lengthy exposure to sunlight.
