Travertine and Plasterboard query.

[davebathroom]

Hi, just joined, hello everyone!

I would like some advice if possible please.

I am a bathroom fitter and have a travertine job to do. The walls are 12.5mm unskimmed plasterboard screwed to 400mm centres timber with 1 noggin half way up the wall. Moisture resistant board is in the shower area which I plan to tank.
I will also seal the tiles after fitting, then after grouting.
Do you think it will be ok to use 12mm travertine(400x200 approx, honed and filled) on this board? I realise it will be close to or slightly over the 32kg sq/m recommendation.
Do I need to add any more noggins?

Thanks a lot!
Dave.

how much do the tiles weigh per m2...don't forget you have to allow approx. 2kg per m2 for the adhesive and grout..

Hi, thanks for the reply. I don't know what the weight is per sq/m, how do I work it out? Will do a search and see if I can find the answer.
Thanks.
Dave.

Just used an online materials calculator which says the tiles are 30kg per sq/m. Not sure how accurate it is though.

you need to make sure you have plenty of noggins to make sure the plaster board is well fixed , but the weight limits are for what the plaster board can take, regardless of how well its fixed....if you get what I mean..

should be just on the limit then...

so I wouldn't have a problem with fixing them..
