Brown Wave 3D Ledger Panel 6 in. x 24 in. Wall Tile is a Natural Stone Sandstone with a blend of earthy brown tones. The tile features random strips of stacked stone glued together for ease of installation. Each piece is of varying thickness that demonstrates a unique 3-dimensional look. Each panel has an S-shaped end that helps interlock the pieces and enhance the random look. This tile can easily be laid in a pattern or single layout and is suitable for residential and commercial installations. 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.
