Gyvlon / Calcium Sulphate and DPM's.

Afternoon chaps (and chappesses !),

Does / has anyone applied a surface applied moisture membrane the above type of screeds, if so who's, what and how.

 

You can't apply a Dpm to them until they are dry, work that out!!!

 

Only really useful dpming gyvlon for wood dropping Rh below 65%

 

presuming there's u/f heating pipes involved somewhere too?

 

Not necessarily, just in general.

 

known a few jobs to have problems with a gyvlon subfloor, its hard to test for moisture cause it dosent dry consistantly.
