I need to tile over a concrete floor on ground level (Utility & WC) and a first-floor timber floorboard floor (bathroom).
I was planning to stick some Schluter DITRA 25 Uncoupling Membrane down which I can fit directly on the concrete floor.
Do I need to put cement boards on the bathroom floorboards before the uncoupling membrane or can I put the membrane down without the cement boards?
