Natural stone products inherently lack uniformity and are subject to variation in color, shade, finish, etc. It is recommended to blend tiles from different boxes when installing. Natural stones may be characterized by dry seams and pits that are often filled. The filling can work its way out and it may be necessary to refill these voids as part of a normal maintenance procedure. All natural stone products should be sealed with a penetrating sealer.
