Weight of Limestone & Travertine per square meter?

[des511]

Thats 4kg for adhesive and 2kg for grout per m2 - 24kg/m2. Hard hat and body armour may be a better solution, though re-boarding as I previously suggested may be a cheaper option.

Anyone know where I can get rust proof armour

You`ll probably be fine mate. As with most things i would imagine the weight figures are on the safe side. As it`s your bathroom i would personally go for it, if it was for a customer then that maybe a different story

If it was large format ties id be cautious but 10 by 10s no problem

Do not men to question you but if you get 5 m2 to a 15 kg tub that is 3kg per m2 and you get 40 m2 to 10kg bag that is 3.25 kg per m2 for grout and adhesive.

What a great forum with all the helpful advice I have been given so far. The tiles that I am thinking of using are 30.5cm by 30.5cm limestone which are 10mm thick. I am moving away from the same size tile in Travertine as from what I have learned is that I would have to butter the back of the tile to file the holes and also apply adheasive to the wall which would up the weight even more. I have paid a visit to a tile shop and they told me that some of the ceramics weigh more than natural stone. Loks like the only thing that I can put on the wall without risk is paint or wallpaper that looks like limestone

Do you know the weight of the limestone if it is the same as the trav 18kg the adhesive and grout are 3.25kg that is 21.25kg 1.25kg over the limit (not worth worrying about m8)

.5 of a mm come on give me a break. I did a floor a couple of weeks back and the tiles were 453x453 does my head in try to do mental gymnastics for my set-out where do they get these measurements from GEEEEEEZ.

And limestone is supposed to have a rectified edge come on you lousy manufactures get metric and set the saw correcty. :mad2:

Oh!! and I'd still go for laying your limestone des511

But as others have said there are options but cost will play a big part.

Most of the bags of adhesive I use are 20 or 22kg, they give approx coverage of about 4-5m2 which is stated on the back. if you are using adhesive in 10kg bags that give 4m2 I would be really interested to know cos it will be much cheaper.

As for tubs, I don't use tubbed stuff for stone. If I do use tubbed stuff, it all depends on the area to be tiled and what coverage I would need - wet areas I use a BAL thinbed/solid bed trowel which uses more adhesive.

Try using BAL white star 15 kg will give you 5m2

White star was the only tubbed stuff I used. As for the question by the original poster, I wouldn't use it on stone, therefore my responses were in relation to using bagged stuff. The general concensus on the forums by much more experienced tilers than me is that you will only get 4 to 5m2 out of a 20kg bag of powder.

As the poster was questioning the max weight of skimmed plasterboard and was wanting to fix travertine, I quite rightly stated that with the adhesive and grout, he would be exceeding the maximum safe limits for that substrate and he needs to think again.

You obviously have a different opinion and that is fine. However, even with your own figures, 3kg of white star per m2 plus his 18kg for tiles still exceeds the safe limits for skimmed plasterboard, not allowing for the additional weight of the grout. If he decides to follow your advice that is his choice but personally if it was my children sat in the bath with the possibility of 25 or 30kgs of tile falling on them because I had ignored valid, correct advice I would be mortified.
