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.
If that is the case, you can, in fact, remove the tiles and put new tiles on the old cement, provided that the surface is level. If the surface is not level, you would have to put a coat of mortar on top of the cement; you will have to mix a binder (epoxy) with the mortar, as cement does not stick to cement. Since you're going through all that work anyway, it's probably just easier to start over again, with new cement board backing.
