Ledger panels make for a great accent wall, fireplace surround or backsplash. Ledger panels are versatile and can be used inside as well as outside. Stacked stone looks seamless with the 6x24 overlapping panels. Created in a variety of looks from traditional brick to a white panel with a sparkle, there is something to match any décor. Choose from quartzite, slate, or travertine. Each panel is 6 inches x 24 inches, which is 1 square foot. Use the same calculation as you would for your flooring, which is calculate your total square footage for the area and then add about 10% for waste for a rectangular space. Add more pieces if you have many cuts. Make sure to use thinset meant for heavy tiles such as Mapei Ultraflex LFT.
