ᐅ Is it possible to tile over existing tiles?

We also had to deal with this issue. The old tiles were damaged and cracked. The size was outdated as well, so we decided to tile over them with new tiles. The new tiles are 4.8 mm (0.19 inches) thick, measuring 45x90 cm (18x35 inches), and have a modern gray-brown color. The floor was leveled, and the new tiles were installed on top. This was done without any dirt, dust, or mess. Everything went smoothly and now it looks like new again.
Best regards

Hello,

Thank you all for the many helpful responses. What Annegret described was also our initial idea. However, we had a tiler come to inspect, and he found that the old tiles were too loose and the floor was not level. Therefore, the tiles and the floor do not meet the requirements. We will have the old tiles removed, and then the floor will be leveled.

Kind regards

Usually, the old tiled floor can remain in place. This avoids hassle, mess, and is much more cost-effective. However, the floor must be well prepared, meaning properly primed. I prefer slim porcelain tiles, which are available in thicknesses starting from 3.5mm (0.14 inches). In this case, the subfloor must be flawless, but small unevenness of up to 2-3mm (0.08-0.12 inches) can be leveled out.

Hi,
Thank you for your suggestion. Covering the tiles would have been the best solution for me as well, especially to avoid the mess. But about 60% of the tiles are loose, and the new tiles won’t adhere properly in those areas. So now we are removing the old tiles, and the tiler will come next week.

But for me, the risk would be too high that the tiles being glued on simply won’t hold. In that case, the work would be wasted, and then the old tiles would still have to be removed.
