As with all natural stone products, there is some inherent risk of staining. Stone sealers or impregnators can provide protection against stains. Using stone impregnators or sealers is not required. They will both provide protection from staining, but can alter the appearance of our stone tiles. There are two main types of stone sealers: impregnators and sealers/enhancers. Impregnators penetrate the stone and protect from within by filling all pores and cavities with a protectant. Impregnators retain the natural appearance of the stone as much as possible. Impregnators, such as Miracle Sealants 511 Impregnator (and similar products), offer moderate stain protection. Follow manufacturer’s directions. Stone sealers/enhancers are a durable coating that bonds to the surface of the stone. These products slightly darken the stone color, look wet and have a gloss finish. Sealers/Enhancers, such as Miracle Sealants 1-Step Natural Stone Sealer and Color Enhancer (and similar products), provide a high level of stain protection. Follow manufacturer’s directions. Below are examples of each of our Aspect Stone tiles in an untreated, raw state, with an impregnator, and with a sealer/enhancer.
