Dural On Anhydrite

[hmtiling]

Hello all. Got a large area of anhydrite that's having Durabase matting on it.
Just wondering what adhesive you guys prefer to use with it. I'm thinking Granfix CSA as it's standard setting and i can mix a load at a time, as i said it's a big area.
All input appreciated, cheers.

Anything gypsum based really mate, anhyfix from Tilemaster is all I've ever used on theses screeds, brilliant product.

My local tile shop has just started dealing with them on my recommendation from the recommendations on here if that makes sense?
What's the pot life like?

Not bad at this time of year, maybe 30-40 mins before it starts to get a bit stiff. For fixing a membrane you would usually mix it a bit wetter so that'll add 5-10 mins to the pot life. If you pre-cut your durabase you'll have no problem mixing a bag at a time.

I have a question.

Once the dural is down, do you still use the gypsum addy for the tiles or revert back to cement?

Back to cement, mainly for cost reasons.

No, Like Bryan states, go back to you Cement Based SPF

It's also worth mentioning that the gypsum adhesives are not suitable to be used in wet areas so, if you were using your durabase as a waterproofing membrane, it would have to be cement based ontop.
