Ask a Tradesman. Best Answer. You can tile over the current tiles, and as another tradesman has stated please check the tiles are sound and not loose as this would cause problems later. Should they be loose, remove these and level the hole/gap to match the existing tiles, either with bonding/tile adhesive.
Tile Over Tile. If the ceramic tiles are well bonded to the wall, it is possible to install new tiles right on top of the old ones. This technique works well in backsplash areas, because the new thickness of the wall won't be too noticeable. Use a cement-based thinset mortar to bond the new tiles onto the old ones. Beat the tiles in with a rubber mallet to keep them level and let the mortar set up for about 48 hours before grouting. Hide the edges of the installation with rail moldings or decorative tile moldings to hide the edges of both sets of tile.
