Upscape Tile’s Tile’s Sliced Pebble Coal Mosaic is an ideal blend of gorgeous gray hues offered in an enchanting mix of pebble sizes. Durable and water-resistant, these natural marble pebbles are as versatile as they are stunning. Use them in high traffic areas – such as on walls, floors and countertops – in both homes and commercial properties. In the bath, they make an especially impressive design statement on shower floors or when used to create a unique backsplash or tub surround. Full of possibilities, these tumbled marble pebbles add texture and dimension to any space. Note: Please inspect all tiles before installation, as natural stone products inherently lack uniformity and are subject to variation in color, shade, finish, etc., so 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.
