First, I am new to these forums, so I apologise if this is not in the right area.
We are about to start renovating our kitchen/dining room. At the moment there are tiles over floorboards. The flooring is on piers with 450mm centres for the joists.
The problem is that the tiles are cracked (plus they only placed them up to the cabinets, not under them and we are replacing the cabinets).
We have had the piers levelled, including the installation of some additional piers to help keep the floor stable.
My question is what should I put down to replace the original floorboards? From what I can see the original boards are warped in places (because the previous owners didn't keep the floor level). So, I want to rip up the tiles and floorboards and replace the lot. I want to tile the kitchen/dining room.
From what I can see there are three options:
1) Hardward - not really pratical/useful since they are going to be covered and I won't get the full effect, except that they might be more stable.
2) Particleboard - yellow or red tongue. The 450mm joists means that I can use yellow tongue, but if red tongue would be better I am happy to pay extra.
3) Compressed fibre cement - either 15mm or 18mm. The problem is the weight and installation/cutting issues.
So, I was hoping that either tilers or someone that has done this could reply. I have spoken to a couple of tilers and some handymen, and got mixed results. I have been told about using tile underlay on top of yellow tongue, but one tiler hadn't heard of it and the other said that he used it but it allows too much movement in his tiles and the grout needs to be regularly replaced.
Has someone out there gone some advice to provide?
a) Yellow/red tongue with tile underlay
b) fibre cement 15 or 18mm
Thanks for the advice,
