Some products will temporarily protect wood from liquids, but they aren't effective if the liquids are abundant or will pool on the surface. Once liquid penetrates its seal, wood will warp. Such a floor will need sanding, restaining, and resealing, which is a labor-intensive, costly process. Natural stone has been used since man began constructing buildings. The most popular stone floors today are marble and granite.
Marble is a beautiful, but expensive floor covering.
Polished and honed marble should be topped with a sealer that's designed for marble. Travertine marble should not be sealed but cleaned often with neutral cleaners. Heavy detergents or abrasives should never be used on these floors. Marble is a form of limestone, or an alkali. It's a mistake to put marble in restrooms, locker areas, and food areas, because the alkali will be damaged by acids in cleaning compounds, foods, and other organic materials.
