Substrate weight limits are given for a reason. They may or may not be conservative and we,

I agree on the first part Russ, but not the second. It would be unthinkable for the upper limit to not have a reserve and where safety is an issue a very healthy reserve at that. By that I'm not implying that thay can be taken with a pinch of salt, but under full and careful consideration (as I indicated in my post) it would be reasonable to go over to a slight degree.

Good point though, and although I am more than satisfied that my plasterboard (especially the way it’s solidly fixed) will take the weight. I did do the calculations just so I don't maim or mortally injure my beautiful 4 yr old daughter Nicole and my 2 yr old boy Leon. - After all they are joint heirs to my overdraft and it would be a tad upsetting to see them crushed under the weight of ancient travertine stone as it parts company with the aformentioned substrate due to the criminal negligence of their dad! In any case I need my son Leon to continue to disgrace or tarnish the family name as I no doubt have!

..And if I may play the Devils advocate for a moment - just for the record, in the known universe, how many unsuspecting little one's have tragically met their demise at the sudden and catstrophic failure of a substrate... whilst innocently playing in the bathtub? -

Dam if you didn't get me thinking though (and I hate doing that!) So, I did the maths:-

1 off 450 x 450 travertine stone tile = 4.7Kg/tile, which equates to:-
4.938 tiles for 1sq m. Now 4.938 x 4.7kg = 23.2Kg Add adhesive and grout @ 6Kg/m (thanks for the stats Oli) and we have a total weight of 29.2Kg Plasterboard weight limit = 32Kg….. Leaving me with 2.8kg spare! So Hallelujah and praise be to the Lord....my kids have been spared!

PPS Dave Ramsden, What don't you like about Dot n dab AND screws... It's only a precaution, dead easy to do makes it bomb proof - on the belt n braces principal! Or did I misunderstand you? Or put it like this, a few years ago someone asked a pilot why only planes with 4 engines were allowed to fly accross the Atlantic. The Pilot replied "because they don't make airplanes with more than 4 engines"!

PPS. BTW, My (some say warped and twisted!) sense of humour is intended to raise a smile and never to cause offence. I add this note in respect and as a precautionary measure, for those granite tough, hard nosed pro tilers who may be hiding an overly sensitive or far more gentle side to their character. ..you know who you are! :lol: :lol:

I wouldn't be so sure mate. When i first started coming on this forum, the weight limit for Plaster Render was being quoted at 25kg/m², and in that time it's been lowered to 20kg/m². I can only assume the reason it's been lowered, is that it was found to be incorrect due to a fail at below 25kg/m². To be fair, this is an assumption on my part, but is it any less valid than your assumption that there is a healthy reserve?

Can you link me to where it states that members etc have advised that tiling to plaster skim the limit is 25kg....i don't ever remember that bieng mentioned..

I am glad that you have taken my infomation on board and taken the sensible step of weighing your tiles to find out how heavy they are. In this case you have discovered that you are within the safe limits for the substrate that you are tiling on to and i am pleased that you are not going to be risking danger because of weight issues.

I take your point that there may well be a reserve built into the boards but we (certainly mods and admin) members on here will not recommend that these limits be exceeded in any circumstances as it would be "difficult" legally if the worse should happen. As it is you own property and your own family that is being exposed to any potential danger then that is entirely your concern and you make your call as you see it.

I am called Grumpy just as an amusing screen name as I had some issues when learning my trade regarding grouting...lol...anybody that knows me knows that I am anything but...

Ok..you used the phrase plaster render...not sand/cement....:smilewinkgrin:..

Now we know what you meant..

Not sand and cement, sorry my terminology isn't great lol! I'm talking about Skim and Set (which i've always refered to as a Plaster Render).
