How to Tile Over Tiles
After ensuring the suitability of tiling over existing tiles, you can start the retiling project if it is safe.
If you plan to DIY the process, the following is a step-by-step guide on tiling over existing tiles.
Step 1: Prepare the Surface
Remove and retile all the loose tiles, and replace them if damaged.
Next, clean the surface thoroughly using sugar soap and warm water. Now coat the surface with acrylic primer by adding some sand to it.
Step 2: Choose the Right Tile
Tiling over the existing tiles differs from tiling on the subfloor. Hence, when choosing the tile, you must select a light and thin tile with high durability.
Especially when you work on surfaces like plasterboard backers, the weight of the tiles is one of the crucial factors you must consider. Therefore, ceramic tiles are the most suitable option.
Step 3: Purchase the Best Adhesive
Step 4: Planning
Check the size of the surface, take the required measurements, and plan your project before starting work.
Step 5: Install the Tiles
Carefully align each tile and use the tile spacer to obtain even grout lines. Cut the tiles using the tiles when necessary.
Step 6: Grout
Like regular tiling, you must grout the gaps when tiling over tiles. You can use a grout float for grout, and to neaten the line, use finishing tools.
The Types of Tiles Suitable for Tiling Over Tiles
Most tiled surfaces will be suitable for retiling over them if they are in good condition.
In contrast, if you have installed softer vinyl, quartz, or composite tiles, then retiling over these tiles is not possible.
Further, you must de-grease the tile surface before tiling over them.
In most cases, the best option is to remove the old tiles, prepare the subfloor, and then retile. 30 x 30 cm ceramic tiles and 15 x 15 cm porcelain tiles are best for retiling over existing tiles.
Pros and Cons of Tiling Over Tiles
Similar to many other projects, tiling over tiles has advantages and disadvantages. Knowing the pros and cons of doing so is essential if you try to retile on top of the old tiles.
