tiling-wall strength?

hotcookie101

I just want to know if my walls can take the tiles i want! The bathroom has 3 original solid walls(rendered), and one stud wall. We are stripping off all tiles, going to reboard the stud wall, and skim the others (to cover up a really bad plaster effect-artex has nothing on this!)
I REALLY fancy travertine tiles for the walls, 10mm thick, but I keep reading conflicting advice re wall strength etc-can I put these tiles up? It has 10mm thick ceramic tiles on there already. Our friend who is going to do the plastering says it will be fine, as does a fried who is a tiler, but I keep reading things about plastered walls and max weights/m2.
Thanks

You can put up travertine no problem on a stud wall. I chose to ply my own stud wall in bathroom, but i have since tiled a bathroom with 600x400 travertine all on plasterboard stud walls.

Can I put it up on plastered walls though? We only have 1 stud wall, which will be reboarded, but the other 2 are solid plastered walls. We will also need to skim the boarded walls (well the top half anyway as it won't be tiles and just painted.
Thanks

Good morning: Technical guidance is available from Bal ....but if your tiler is a professional he/she would be best placed to advise.;)

The two friends we have asked are professionals (BUT-it was Saturday night when we rang them,so drink had been taken! :eek: )
I can see if we use plain boards that it will be ok, its more if the normal, unboarded internally rendered/plastered walls would be able to cope-as its one of these which will be fully tiled from floor to ceiling

Sand cement render can hold up to 50kg/m2 (that's 20mm thick marble)

Plaster skim can hold up to 20kg/m2 which is 10mm thick stone at an absolute push (actually that generally weighs closer to 22kg/m2)

plwood and moisture do not go well together,Natural stones are porous and grout is only water resistant,Unless tanked its a recipe for disaster

WBP ply, with natural stone, cemented with BAL, ARDEX etc and grouted properly will last longer for absolutely years. There is NO recipe for disaster!!!

Adhesives and grouts are not waterproof

I have removed too many shower cubicles lined in ply that have not be tanked in either membrane or rubber tanking kit where the grout has cracked /tiles fallen off after water ingress

Maybe you have, but if the workmanship was good in the first place i guess the vast majority (if not all) would still be standing firm and dry(inside) today..

British Standards were altered in 1998 to specifiy that wooden substrates were unsuitable for tiling when used in wet areas. Building regs on the whole are based on British standards, in this particualr case they are.

It's why Tile backer board exists.

Tanked plasterboard is actually a more suitable substrate than any form of plywood.
