Casa Blend 3D Honed Ledger Concer Panel 6 in. x 18 in. Wall Tile is a Natural Stone Travertine with neutral cream tones desgined for corner use. Strips of stone are stacked and glued together to form a 6 in. x 18 in. panel that is easy to install. This tile can easily be laid in a pattern or single layout and is suitable for residential and commercial installations. Note: 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. MSIs Interlocking Z Feature allows the panels to fit together easily, just like puzzle pieces. Achieving a seamless fit has never been easier.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.
