Natural Stone Mosaics are on a mesh sheet for ease of installation. These tiles can be installed in a wide variety of design schemes, including kitchens and bathrooms. The durable surface makes it an ideal choice for water exposed and high use areas throughout the home, including a shower, or kitchen backsplash.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. For SAMPLE ORDERS - Order affordable samples before you place an actual full order. Samples are usually 4inch x 4inch or 6inch x 6inch based on the type of tile. These samples are just a representation of the actual tiles for you to see the color and texture of the tiles. Samples are shipped by Fedex / USPS ground service, sometimes the samples are not in good shape on delivery as they are individually packed and lack the proper safe packaging as the actual tile order. Nevertheless they solve the purpose of showing you the color, texture and the pattern of the tiles.
