Ceramic tiling specifications include tile size, thickness, water absorption rate, surface finish, PEI rating, slip resistance, edge type, and colour/pattern variations. Tile sizes range from small mosaics to large formats, with thickness varying based on use. Water absorption rates indicate suitability for wet areas, while surface finishes, such as matte or glossy, affect appearance and maintenance. PEI ratings measure hardness and wear resistance, and slip resistance is crucial for safety. Edge types, like rectified or cushioned, influence installation precision. These specifications ensure ceramic tiles meet both functional and aesthetic needs.
