Moderno Blanco Interlocking 12 in. x 18 in. Metal/Stone Blend Mosaic Wall Tile, it’s easy to add a splash of contemporary styling to your decor. Mounted on a 12 in. x 18 in. mesh sheet, this tile is easy to install in a variety of design schemes. With random length pieces of multi colored natural stone and metal, this tile creates a distinct pattern. Note: Inspect all tiles before installation. 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.
