UFH floor Tiling Problem

[Flintstone]

You need the height of all floor areas to be the same.

Finally started the ufh commissioning and everything going well until I noticed a couple of hairline cracks , i d done the correct thing i.e. Started at minimum for 3 days then increase 4 degrees a day , I'm up to flow temp of 46 degrees ATM , I've read on here to take it to a maximum of 55 degrees then reverse the process . I'm definitely going to put a uncoupled membrane in now with expansion joints . Thinking of marble tiles as tops tiles have them on offer , using flexible addy for both membrane and tiles , any suggestions on the adhesive , I thought maybe bal rapid flexi in white as they are a light grey tile

I'd use a rapid grey for the mat and a semi rapid white for the stone
