Sage Green Ledger Panel 6 in. x 24 in. Wall Tile is a Natural Stone Quartzite with green tones. Seemingly random strips of tile are glued together to form a panel that is easy to install. This frost resistant tile is suitable for indoor or outdoor walls in 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.
