I know this has probably been covered hundreds of times but after searching I can't decide.
I'm having an extension on the rear of our house. The kitchen area is having a wet ufh of Solfex warmboard. A 18mm overlay system ontop of the concrete slab. I've been recommended to lay screed boards ontop then I can travertine tile to that 45sqm.
Do I simply loose lay the screed boards then flexible adhesive the tiling?
Also should I use 6/9/12mm boards? 12mm works best as it'll bring the floor level back to its original height.
