Hi there,
I've currently got a series of joists in my kitchen as the floor is being redone after cowboy builders laid 12mm ply over joists with natural slate over the top whilst we were away for a few days. I don't need to tell you the outcome.
We really want to get it right this time and are being very cautious with the best approach. We intend to tile with porcelain - I will look into flexible adhesives and grout elsewhere but I know BAL are recommended. I've also installed some kingspan insulation.
The joists are 6 x 3 inch approx with 400ish centres - its an old building.
Im looking at the following options:
1. 25mm WBP ply - tile directly onto it after a suitable primer or matting. Just concerned with the lack of T&G for the surfaces not on the joists.
2. 18mm chipboard with t&g that I can glue along the joints. Overboard with 6mm hardbacker or plywood.
3. 18mm OSB 3 t&g with the hardibacker or ply overboard
Can anyone advise please? The last thing I want is all the tiles coming loose again!
Thanks for your help
