Hi
I need advice on a preparing a floating wood kitchen floor (16m2).
It was previously tiled (600mm x 600mm porc), and now tiles are cracking. It has electric UFH, that wasnt over laid with SLC, and that is laid on the wood floor. The tiler was supposed to have laid Ditra matting, but when some cracked tiles were replaced there wasnt any matting and ofcourse some UFH wires were damaged. Replaced tiles still crack.
The customer is now thinking of having the whole lot ripped out to start again, properly!

Would it be best to board the floor, then lay a mat system (Durabase etc.), lay the UFH, cover in SLC (which I prefer to do anyway) and re-tile (same size tiles)?

cheers

The best option is not to tile it as it is, and over boarding will not stop a bouncy floating floor..

You can remove the floor and screed or install a frame then re-board but IMO it should not be tiled as it is.. that is why it had cracked.. deflection.

The reason that it failed is that it is a floating floor ..simple. Best way is to rip it out and make sure the floor is solid, either screed or new wood floor on solid joists.

Cheers.
i was just going to say that perhaps I should say no to the customer and suggest that the floor needs re-building as you say.
