Piece to piece variation in shade or color are inherent in all natural stone products; therefore, when installing natural stone tile, it is recommended to mix tiles from several boxes at a time during installation to achieve the best range of color. When installing white marble, you must use a white thinset; using grey thinset will leave trowel lines and could stain the marble. As natural stone products, it is recommended that these be sealed to extend their longevity.
