Wooden plank subfloor for tiling over Advice and information on tiling and fixing tiles to a variety of surfaces

[Conor333]

Had a leak in the bathroom.

Removed tiles and old laminate type subfloor.
Wooden planks sitting on joist now. Some of the planks were damp and had a black layer on them. Dried them out and will apply a treatment to them. Are they suitable for reuse with a hardie backer board on top prior to tiling? Or should I remove and put down plywood?

Also, if I keep them, what adhesive can I use between them and the backer board?

Thanks

Hi connor333
The floorboards will be fine, follow the installation instructions on the Hardiebacker web site.

Thanks. Would a mat like ditra be sufficient or should I use a cement backer board?

Hi connor333
There are many decoupling mats on the market but if you are just doing the loo may be worth finding a friendly tiler who can sell you a piece off a roll. Make sure your floor is sound and fixed down and remove the loo, hand basin and bath side framework to give a clear working area.
