Tiling over tiles isn’t as straight forward as it sounds, but it is possible. It’s an effective way to save time and money on your renos, while also keeping waste out of landfill. However, if your tiles are showing signs of damage or wear, you’re better off ripping them out to avoid bigger issues down the track. The remaining tile will also need to be roughed up or scored for the new tiles to adhere to the face. This can be quite difficult with some of the quality tiles as this is something that tiles are made to withstand to some extent.
