Hello
I am having to replace a floor 13metres by 6 metres in my house which is in France...cracked ceramic tiles stuck on a blown chipboard floor with warped and rotten joists cut in to 35cm square wooden beams. The floor covers lounge and kitchen NO bathroom...that will be a different thread / problem.
Current plan is to rip out the whole lot repace the beams with RSJ's cut in new joists which will probably be 70mm by 200mm (French size timber) on 400mm centers with noggins and then wbp 20mm ply the lot.
As I am not a tyler i checked on the internet and thee are a lots of posts which suggest using hardiboard aquapanel or similar on top of 18mm ply..it seems that these will eliminate all the timber movement....although with 200mm screw fixings I cant see how this board can do anything other than follow the plys movements.
The bloke in our local DIY store reckons its good emough to prime the ply and then lay the tiles directly onto the ply with a flexi cement adhesive..my plasterer reckons the same...
Any advice.....i cant afford to get this wrong
Thanks
