Well that would have at least taken the issues of the screed cracking and not being 100% dry away...

Can the uncoupler be put down on Wet Under floor heating?

 

[Spare Tool]

Yes, long as its sealed between the runs

 

[Spare Tool]

Oh and as long as its Dural ci mat or Ditra, not just a crackmat

On a not dry screed I think you mean. S2 is required I think. I'd use ultimate

Picture of progress today.

After a bit of a heated (from his side) discussion he agreed to put down dural dura membrane and self level compound near the door to level things out.

He disagreed his tiler had done anything wrong and as he had used him on a number of jobs, there was no way the tiles could be lifted of impacted.
I pointed him to the direction of the contract where it clearly stated the membrane was required however he believed as we have under floor heating, it would impact it!

Anyway we talked him through the proof as to why it was required and the advise many of you gave on this forum and he finally 'reluctantly' agreed to get some while saying he just wanted to get through our job!

He then tried lifting up a tile, quite aggressively and within 5-10seconds the whole tile was lifted without any screed or damage to it.

I managed to calm him down at the end of it and ended on a good note but he clearly thought we was just making things difficult.
We cannot afford to get this wrong again hence we are so anxious and worried, hopefully all will be ok now...

Builders left for the day so went to check how they got on.
Held a 1meter spirit level against some areas of the floor that had the Dural put down and there are still some areas that are uneven - 2mm-3mm.

Can this be an issue?

I would get a different tiler, some one proven who can do the job properly. Although you have Dural down, his fixing methods aren't going to change. The builder pulled one up in 10 seconds and I am not at all supprised.

Not to a tiler
