Yes, you can paint tile! In fact, there is specialist tile paint that you can use to ensure your tiles get the best finish possible. However there are some things to consider before painting your tiles. Tiles are not designed to be painted on and are often glazed to repel things like dirt, dust and grime. You need to ensure that you sand any tiles before painting to ensure the paint sticks to the tile and gives a matte finish. You also need to ensure the tile is clean and any dirt or grime has been cleaned off prior to painting. Lastly, you need to ensure you are using specialist tile or epoxy paint to ensure you get the best results.
