I have just seen this table and i am disappointed i will not be able to use stone tiles in our new bathroom.

The walls are all plasterboarded (cement board in shower area), so i think we are limited to only 20kg/m of weight. Is this correct ? This means i can only really use an 8-10mm ceramic.

plasterboard you can go up to 28kgm2

 

[White Room]

Plasterboard can take 32kg m2

 

[doug boardley]

......including addy and grout, typically 4kgm2

That 20KG seems low on plasterboard. I am sure its more.
Put it this way LOTS of people tile their bathrooms with 12mm porcelain tiles. Not heard of anyone having a tile drop on their head yet!

I THINK YOU WILL BE RECIEVING SOME ENCOURAGING NEWS ON THIS FORUM SOON!!

Ok, but you have all given slightly different answers (28 or 32). someone on another forum has said 20kg because i have plastered the PB. Clean PB can take more weight because it doesnt have a skim on it.

Still confused. I did think 20kg was a bit low as well.

I was hoping to use 10mm limestone and that will be 31kg. So under one persons weight limit and over the other.

any more views ?

You did not say it was skimmed.?

So it is 20kg if it is skimmed and 32kg if not.. these weights include adhesive/grout

 

[White Room]

Did'nt realise it was skimmed, as above 20kg m2

 

[doug boardley]

ahh right, skimmed plasterboard will only take a maximum of 20kgm2, unskimmed will take 32kgm2 including adhesive and grout, which weighs in at about 4kgm2

i only skimmed it last week and i could have saved a load of time. I intend to tile the whole wall as it is a slope in the loft. gutted.
