Hi Guys.
Tiling a floor next week over a suspended timber subfloor. I'm first putting Ditra down with an S2 Adhesive over the ply, then tiling a limestone floor. Whats you're opinions on using Mapei Adesilex p9 ontop of the ditra to stick the stone?

Think you might struggle to get it right now. There have been some problems reported with AF200 (but not publicised)
I've used on good new timber floors with no issues though.
I often use different brands tbh Mapei VS90 plus being one. Any of the main flooring brands equivalent adhesives do the same job. Ardex only recommend a couple of brands because they haven’t tested any others but I have.
What type of problems are being ‘rumoured’?

Well that’s obvious.:rolleyes:I thought you might have heard something more specific as to why.
Could be something as silly as someone using it on screeds not dry enough or releasing agents on the ply.

You know how poor UK screeds and concrete floors can be. So following the instructions on the pot, they go and use it on unprimed, dusty, massively uneven floors and low and behold - the Ditra isn't stuck at all.
It's basically not idiot-proof.
