I’m looking to lay porcelain tiles in a kitchen diner (~22m2). I have a floating floor, which is not suitable for tile. I’ve been quotes for Ditra, but Ditra is for horizontal movement. My current sub floor is:
- Bison Block and Beam.
- 20mm insulation
- DPM (blue plastic sheet)
- 18mm WBP tongue and groove
I’m planning on removing the WBP, DPM and insulation. And I don’t know if there is a DPM under the Bison.
I considered a bounded screed, but this is likely to be 40mm thick with no insulations (too cold). I only have 55mm from the Bison to the top of the tile.
So I’m looking to replace it with:
- Bison Block and Beam
- Ardex DPM 1 c (just encase)
- Marmox 40mm Multiboard with a flexible adhesive.
- Ditra
The Marmox (and Ditra) will form the vapour barrier to protect the tile.
Would this subfloor take tile? Does any see any problems?
Many thanks
