At Sir Grout of New Castle County we understand most natural stone surfaces are porous, and if left exposed, will absorb water, dirt and other fluids such as grease, oil, wine, etc. A high-quality Winterthur Stone sealing treatment will save your stone from exposure, and protect the luster of the natural grain or finish of your stone, no matter the type.
