Repairing loose tiles on Electric UFH

[Stef]

we always use BAL as already stated thats why when i looked at this floor and there was no bond between adhesive & tile then i knew that it hadnt been rapid/flex, THERE I GO AGAIN, that had been used. to b honest it wasnt the best of jobs, it was a guy that his dad knew, we all know 1 of them!! i reckon he swiped the BAL n used a cheap ceramic adhesive to try & lay porcelain.

I've skimmed this tread and don't know too much about BAL adhesives. However, you say that no self levelling was used over the UFH so the tiler is effectively fixing porcelain directly to plywood with UFH wires in between. I would only ever use an S2 grade adhesive on plywood (i.e. 2 part adhesive mixed with latex or Ardex x7001) for this configuration.

I think it is possible that the wrong adhesive has been used regardless of any other possible fixing errors.

Your surmising that option, it could have been he mixed the addy to dry or even dust on the backs of tiles, we don't know but it failed..
