White Mountain Crystal Seal™ is a stain resistant sealer for stone, concrete, pavers and unglazed tile. Current advancements in water based acrylic micro-emulsion coatings technology have allowed us to develop the ultimate, long-lasting sealer. It protects against water damage, spalling caused by freeze/thaw conditions, stains from oil or grease, and discoloration from dirt. One coat produces a satin finish while additional coats produce added gloss, color enhancement and protection.
