I about tile my bathroom floor and walls (about 20 sqm all in all) with honed & filled travertine tiles. I have two of my walls that are plasterboard internal stud partitions. The flooring will be 18mm WBP ply as I'm replacing the current uneven 18 mm chipwood T&G floor.
One of my main concerns is to do with the palsterboard walls, will these walls be able to take on the weight of the travertine tiles, each tile is 12mm thick and 40cm by 40cm.? Also, I have stripped all the walls from paint so they are back to plaster and I will use pva bond to seal them. Also, I will be using a good quality tile adhesive (Bal).
I am grateful for any advise.
