Replace Bathroom Floating Floor With Tile Backer Board?
Discussion
Existing bedroom with floating floor is going to have a new en suite built in it. Age of the house I reckon when I look I'll find;
Chipboard Floor
50mm polystyrene insulation
Black plastic DPM 1200 gauge
Block and Beam sub-floor
A nice easy (ha!) and much better job for a tiled floor in my mind would be to rip out the chipboard floor and polystyrene insulation and lay a thick (60mm ish) XPL type tile backer board and lay tiles directly on top of those.
But how will they attach to the subfloor when there's a DPM layer on top of the block and beam? Screw through with backer board fixings?Some sort of adhesive?
In my mind I'd like the make up as;
Tiled finished floor
Electric underfloor heating laid in self level screed
60mm XPL type backer board
DPM
Block and Beam sub-floor.
Anyone tackled something similar?
