Hi, tiled a new house back in the summer, guy rang me yesterday to say couple of tiles loose on one bathroom floor. After recovering from a heart attack (ettringite paranoia! :yikes
I popped to have a look.
Lifted the loose tiles and loads of water underneath, after further inspection it appears his shower (very high pressure/water flow rate) has been leaking a serious amount of water which has found its way from under the tray...under the tiles on two sides.
Prep wise, I followed recommendations for screed i.e laitence properly removed, primed x 3. On lifting the tiles, the backs of them are 100% bonded to adhesive but looks like you can see a surface of anhydrite and primer. I have tiled other screeds in this way, hoping they don't get any leaks..eeek!
Floor now being dried out, leak fixed, I might go for some Gypfix to re lay this one now
Having never had any tiles come loose, I was surprised that this leak caused the tiles to pop so easily. I have seen popped tiles similar to this after a leak on a concrete floor too, laid years ago by someone else, but again a long standing leak.
