can we fix ditra mat down with a gypson adhesive ?

[Rookery]

If my memory serves me well, in the early days didnt Schluter recommend sticking Ditra down with Blue Star?

I remember something similar when we started using it around 1994ish they did say in theory it could be stuck down with wall tile adhesive as it was designed to uncouple.

Not familiar with the af200 specifically but it's perfectly acceptable to use a vanilla adhesive for ditra. The only concern I wold have would be the implication on heavy point loading due to the dimples not being filled with a rigid adhesive but from a practical pontiff view is this really an issue.... Based on Lynn's comments I would suggest not.

The adhesive would spread the same to the fleece backing with cement based or vinyl adhesive. As long as the dovetailed holes are filled above with cement based adhesive as Schluter recommend i can't see it being a loading problem.

Question answered then methinks.

Hi, the AF200 is a good adhesive, please do check the moisture content, I know this has been been mentioned in previous posts, but is important.
The 2 methods to test are the hygrometer box, and carbide bomb.
I would also check with Creative Impressions and Kerakoll for their advice re gypsum friendly adhesives and sticking down the Ditra
