wet UFH/New Screed/Ditra/Marble combination

[jjoc]

guys, just wanted to get your thoughts on a forth-coming marble job, main details are to be:
wet UFH,
60mm S&C screed,
Ditra,
Marble,

Does anyone know how soon you can get on new screed whilst using Ditra? (i've checked the website and its unclear to me)
Obviously I dont want to go on until screed is ready and UFH has been comissioned, but it would be helpful if i could reduce the waiting time of the screed drying. I presume that if you on the screed early using ditra, you have to use a green screed adhesive, is this correct?
Any help is appreciated.

Yes

You can use detra on green screeds a couple of weeks old

Good Luck
