First Time Limestone Floor - Tile Advice

[Bill]

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.

When I began tiling a couple of decades back products such as ditra or dural were unheard of, granted so were anhydrite screeds. So as you can imagine I've fixed countless stone floors without a membrane successfully. However you move with the times so if budget allows I wouldn't advise against using one even if personally on a regular screed (no ufh) I don't think it necessary. We're all about belt and braces on this forum so yes I don't think one is necessary on this install but if the op has the budget to fit one then do it.

If its about budget, doesn't have to be ditra or Dural, tilemaster crack mat only around £4 a metre if you shop about, thin bed of anhyfix for matt, your choice of adhesive on top...sleep easy

what is the down side of these mats compared to a Ditra type?

 

[Old Mod]

They're not waterproof and they can't be used as a vapour barrier.
Although Isomat do a waterproof one.
Not to be confused with Isomat adhesives.

Now there's a question..used the crackmat other week on a trav floor with ufh cuz had to keep levels down to meet up with an existing floor.
As you well know I'm using Dural this week for porc on heated screed..
Think you'll have to make your own mind up on that question mate

[Flintstone]

I have no objections to putting one down if people want it, but I wouldn't demand a Matt down or not tiling it.
