On a timber floor Ardex AF200 or the like is far superior for adhering Ditra imo
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.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.

What type of problems are being ‘rumoured’?
Well that’s obvious.I thought you might have heard something more specific as to why.Not staying stuck!

Could be something as silly as someone using it on screeds not dry enough or releasing agents on the ply.
In that case the AF200 hasn’t failed it just typical plonkers not following basic principles.
From my flooring background I know that for these types of adhesives to be successful on screed/concrete the substrate needs to dry and smooth and not too porous. Most screeds etc aren’t good enough because they are too porous , weak and friable, they aren’t compact enough. You could easily dig into them with a screwdriver etc. They nearly all need a coat of leveller to achieve a suitable finish. Problems also occur if the adhesive dries downwards and skins if you understand me. On a well prepared substrate once it air dries to the point were it becomes tacky to touch then it’s good to go and good luck trying to pull it back up again once it’s dried.I always thought, from it's launch that it wasn't suitable for screeds and concrete. Timber definitely though.
