tiing on green screed

[bugs183]

I've just been on the Schluter Substrates course and they certainly recommend the use of Ditra on green cement screeds, and say themselves that the amount of moisture trapped in the screed is not huge as the chemical reaction uses a good percentage up, and that the residual will escape through the flutings.
yes it does incuur extra cost but if on a limited time scale then this would save a project weeks of delay.

ok thanks for your comments i knew about bal green screed but thats no good with travatine as is only avaible in grey. i think i will tell the customer im not willing to do the job until is dry.

If its travertine you're better laying with Ditra anyway, regardless of how long the screed has been down.

Have used Bal green screed a few times, but just a question would you use green screed adhesive to stick the ditra down if not what adhesive could you use on a green screed in conjunction with the ditra?
