Rejuvenate the stone surfaces of your home with Rainguard Water Sealers Stone Sealer! Our non-toxic and water-based stone sealer formula lasts up to 5 years* and is safe for people, pets, and plants. Rainguard Stone Sealer penetrates the surface and forms an invisible protective barrier that resists weather, water, efflorescence, and stains on unpainted and previously unsealed stone. It helps prevent the growth of mold and mildew, protects against efflorescence, and is safe for indoor or outdoor use with little to no odor and zero VOC’s. Unlike conventional water repellents, our natural Stone Sealer is available in concentrate form so you never have to spend extra money on water and excessive packaging.
