Reinforcing wall with 12 mm ply on to the studs then adhesive & screwing 10mm backerboard on to the ply, what do you think? Would this be affected by thermal expansion?

With new tilers joining all the time this is a very handy post to keep bringing up.

Note to any newbies - make a note of these in your diary, I guarantee you will keep referring to them (if you're doing your job right)

Guys hope you can help I am looking to tile my bathroom and the wife wants 10mm procelain that weigh about 25 kg per M2, I live in a new build house (4years old) and all the walls are internal platerboard cavity metal stud. ive been told that the max load for this should be 32 kg per M2 but the tiler I am looking to use has suggested plying over the top with 9 mm ply and screwing that through the plasterboard and into the metal to stud to give extra support can anyone confirm if this is good advice?

Also the wall area is around 20 M2 so the tile weight will be almost half a ton this sounds huge to me can anyone advise???

Thanks for your help.

Don't use the ply.. it holds less weight and is subjective to more thermal and humidity expansion .. as long as the PB isn't skimmed and not painted,then tile onto the PB..

 

[McDogger]

If the plasterboard is skimmed what would you suggest?

 

[DHTiling]

It it is skimmed, then you need to remove and use either plaster board or tile backer boards..

I seen last week on site, 20mm stone fixed to double layed plasterboard. The stone was 600x1200, finished height 1200mm. The glue behind them was around 10mm. Is this feasible with the 2xplasterboard and that height, or is it inevitable to have problems?

That's an interesting question. Gut reaction is "hell no, that's way too heavy, plasterboard is 32kg/m2 period, no matter how many sheets are screwed together, because it's the tensile strength of the paper to the gypsum that matters.

But gut reactions aren't always based on fact, or correct.

I think you should contact the manufacturer of the plasterboard and ask them, or the tile adhesive manufacturer. We double board sometimes here, but it is more to do with avoiding water vapour penetration to timber framed house core structures than trying to allow heavier tiles to be fixed.

ok. informative tho
doesn't help you much with costing
if you are pro you no whats what.... do you?/?

Could I ask a favour... Could someone in the knowhow copy that table and list all the surfaces that will take the weight? Sorry if its a bugger it would really help me out
