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.
While you can lay tile directly over a concrete slab using thin-set adhesive, donât make the mistake of applying tile directly to a plywood subfloor. No matter how firm the subfloor; the plywood will expand and contract at a different rate as the tile, causing cracks to develop in the grout lines or tiles over time.
