Hi guys.
All the Anhydrite screeds I have done, have UFH (wet) I have always lathered the floor with Weber PR360.
Then applied Ditra with cementious addy.
I have never had any issues, and all the jobs are perfect now as they were when i left. I have even monitored the drying of addy on the primed screed to see if it loosens (doesnt, due to primer sealing/separating the substrate from addy.
I have even left the matting to see if the primer has worked. I physically cant pull the ditra off the floor.
My Question is, even though my method is perfectly fine. Should I start working with primer & gypsum based addy (anhyfix) ??
Thanks in advance.
(My Method: Scrape floor (mutt) Sand floor, Sweep & hoover, Prime lavishly, Apply Ditra/Dura)
