& here's a limestone floor fixed to a screed without a decoupler, all be it a badly laid screed.See - I don't get it with some of you folk - I have fixed thousands of metres of stone without decouplers, many times directly in a sand and cement bed.
All you have to do is make sure is that everything you do is compatible with your workflow.
...and here's another& here's a limestone floor fixed to a screed without a decoupler, all be it a badly laid screed.
I have repaired this floor 3 times, they were told at install to decouple but I'm only a daft tiler, what do I know.

Stone is too soft to fit without decoupling it from the substrate....and here's another View attachment 81780
thanks marc.
So this, in your own opinion, was a badly laid screed....so maybe that was the problem and not the actual fixing?& here's a limestone floor fixed to a screed without a decoupler, all be it a badly laid screed.

Not all did that. I have fixed onto suspended timber with sand and cement and had no problems....it is how you fix them that matters. I wish we had mobile phones 30 years ago that took photos!Tom go on the Schluter course you may be surprised as what you could learn there.
The guy that designed Ditra realised how tiling of old had lasted as long & that was to decouple it from the ground with a layer of sand.
"If the screed is installed properly"If the screed was installed properly it already is decoupled (With styrofoam sheets instead of sand). With or without Ditra you still need to install movement joints. This is the reason for the cracks in the pictures above ( NO movement joints).
I'm not on here for an argument but I would like to see that floor in a years time.Sorry I have no before or during photos but here is one I did not long ago...soft as turkish ceramics..... no decoupler fixed in sand and cement onto a concrete base......

"If the screed is installed properly"
If every screed was fitted this way then there would be no problem, that's where the decoupler comes into its own.
My pictures above are nothing to do with a movement join not being fitted.
No run is more than 3m long & is broken across the door ways, it was a badly fitted screed.
Thanks, that means a lot coming from you.That looks really nice Tom
just work super clean, seal once laid, grout, seal again. thats the plan. anything i should know?assuming they get fixed correctly, what about the cleaning and sealing procedure @Makone
i've been told by the builder that laitence has been removed. the screed was laid three months ago so hopefully its gone off..The Anhydrate-Screed needs to be prepped properly!
1) Calcium-Carbide Moister measurement test. The moisture can't exceed 0.5% (with UFH 0.3%)
2) Laitence layer removed
3) Prime
4) Tiling can begin
5)Decoupling is not needed, to avoid cracking(longevity) movement joints need to be installed correctly!
