Regular polished floor tiles normally undergo a single glaze polishing process, resulting in a gloss finish, but it requires a lot of maintenance to maintain a perfect finish over time. Meanwhile, a “double polished” finish starts with the surface of the glaze being polished, after which the pores of the tile are sealed with micro-quartz crystals, which helps to give the original glaze a shinier appearance and makes it more durable over time. After this process, the floor tile undergoes the polishing process again, obtaining the final result for the tile: a floor tile with a glossier finish, which is better able to withstand any use made of it.
