Hi
I'm a novice myself, but recently tried just that ie. laid new ceramic tiles over old ones (for the shower area). Bunnings recommended a Dunlop product, "Tile on Tile" which is meant exactly for this. I cleaned the old tiles, mixed & spread the "Tile on Tile" then laid the new tiles, and after that filled the pointing with mould-proof coloured grout to match the new tile colour.
Worked like a charm, and it's been a couple of months, no problems at all so far.
Hope this is of help. |
