Because natural stones like marble, granite, sandstone, and travertine are porous, they will soak up oils and other liquids. A sealer for stone will protect the stones and make them last longer where they are used, like on countertops, floors, and walls. The amount of time it takes for liquids to be absorbed depends on the stone. A granite countertop, for example, will absorb liquid more slowly than a sandstone countertop. However, sealers for stone are very durable, and a penetrating sealer for natural stone will ensure that the stone’s beauty lasts for many years.
