Ditra on Anhydrite

[Lee@emctiles]

One of our regulars used it today for first time, I've not heard full review as he called mark @ TileMaster for that, but tiler said it mixes and seems just like any other TM white adhesive.

If a job gets confirmed this weekend I'll be having a go with it, can't wait!

And I never even got offered any adhesive.

I would go down the root of getting the adhesive company to do a spesification and let them do any tests that need doing I would not stick your neck out to far with these screeds.

Will they do a moisture test?

I finally had a look at this floor, and got some more details on it...
There is UFH, and it will be commisioned shortly.
There is celotex all around the perimeter of the floor. Is this usual!?! How do i deal with it (ie. stick the Ditra to it!?!)?
Customer has bought an Epoxy Primer (meant to make a note of brand, but as usual... Forgot), and Weber SPF.

Any thoughts?

Celotex round the edge is to prevent cold bridging. It should normally be covered by the skirtings and plasterboard. It is normally only 25mm thick.

The customer was a little too involved with this one, and he went 40mm!?! Not only that, but he got a little carried away, and did internal walls too... :-/

Me neither!?! Only thing I can come up with is to use Tec 7, to stick the mat to the foam, but no idea what sort of bond it'll give!?! :-/
The screed itself looks like it'll be a pleasure to tile, as it's really flat. Nothing's ever straight forward though is it? Lol

What about if you we're to scrape out some of the foam down to say 10mm and fill it up with levelling compound or adhesive.

Just make sure theprepos done correctly and make sure when you mix the epoxy primer you use a spatula to scrape out all of part a into part be to mix it. Is it a water dispersable primer. They can soften be diluted to make them easier to penetrate the screed surface.
