I did ask this in another thread, but that tuned into a screed sealing discussion, so I'm reposting just this question in the hope of an answer.
We're tiling a is a small bathroom, approximately 1.5m x 2.5m floor area. We're looking at a porcelain floor tile and ceramic wall tile. This is fairly solid suspended timber floor, 100+ years old. Joist spacing is across the 1.5m span with spacing between the joists varying between 250mm and 320mm, so no large spans. We've secured 18mm WBP ply on that. We have UFH between the joists. Do we use a decoupling membrane? I know it'll do nothing for deflection in the floor, but was wondering about expansion and contraction of the ply? Also with regards to sealing the ply, I've read about sealing the back to prevent absorption of moisture from the air below. Is this a requirement or a nice to have?
I'm looking at getting Bal stuff from Topps as they're close by, and seem to give a good price if you just ask nicely. Which Bal adhesive and grout would people recommend for this job?
Thanks
