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

As mentioned, you must select S1 tile adhesive when tiling over tiles. You can refer to the best tile adhesives section for suitable adhesives.

Step 4: Planning

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.
