This product is hand-crafted by master artisans using a process over 150 years old. Low-energy non-fired decorative tile is produced from cement, mineral pigments, ground marble dust, and sand, then pressed and cured to produce one of the most beautiful surfaces on the market. The hand-made nature of cement tile means that no two tiles are alike, with color and pattern variations that give it a beauty similar to natural stone and hardwood surfaces. With proper sealant and care, cement tile makes a great durable surface for residential or commercial floors, walls, and creative uses indoors and outdoors. Note: Cement tiles need to be sealed once or twice, before grouting and general usage.
