[Brinkley]

what was it primed with?

I don't know - I would have to ask the specific question, which I will do when I get the tiler back again. Plasterer who laid the screed coming in the morning and I need to get his opinion before I talk to the tiler again.
Thanks you - I will let you know if I find out!

It might be the worst use of PVA ever

Id doubt it, the guy seems to know what he is doing with the materials and knowledge he has used. BUT you never know!

It could be the UFH leaking? Im too impatient waiting for he answers, i wanna know now! Go take up a tile 🙂

Did you happen to seal both sides of slate before setting them?That would affect the bonding from tile to ditra/dural.

In your opening letter you said" cleaned and wiped on the reverse",wiped with what?

One new floor area - the floor slab was laid in 2 'hits', but the screed was laid over the 2 at the same time. The loose tiles are all over.
Thank you

Can you clarify, was the screed built up in two layers? If any one of these layers were too thin, then it could have de-bonded.
Apart from that everything seems to have been ok, Don't be too hard on your tiler🙂

Why not one hit for the floor size

This exact thing has happened to me I was looking to post this problem.Tiled a barn conversion in Oct sand cement screed primed with acrylic ,laid dural with my own brand ady single part flex and then laid 600x400 slate using customers adhesive( sovereign single part flex). Waited for over a month while continued to finish rest of barn ,2 wet rooms hall etc. In this time kitchen was installed and floor was fine.When returning before xmas to put a finshing seal on this is when I noticed the noise under some of the tiles.Only a few down one side of room but I think it may get worse going back to check and lift a tile.Also noticed 2 cracked tiles in identical corners either side of the slab that the aga sits on ? Strangely the hall and wetrooms are fine the only difference being I used my adhesive (granfix).I am aware that possibly the underfloor has been turned up straight away (the floor was fine before heating was turned on) need to get this confirmed.Spoke to Sovereign they couldnt help much but will come out to look but did offer me free ady ,first time Id used there product.Not looking to blame anyone yet just need a solution ,have been using all my products for years with no probs ,looking forward to replys PS screed was probably the worst I have seen all over the place.
