Exceeding substrate weight limits.

[Dougs Third Go]

i doubt you'll find any long standing tiler that hasn't exceeded weight limits from time to time. I did a little test on a skimmed plasterboard with a porc tile, left it a couple of days and tried taking it off....it pulled a big hole in the plasterboard but was still stuck to the skim..weird!

I once seen 15 mm thick granite stuck to a plastered wall with no apparent problems, one piece was actually on the ceiling section of a long alcove. I'm well aware of the reality of what can be achieved in real world. There are others factors that would dictate how much if at all you would want to breach the limits such as if the wall was plumb and if the bottom row of tiles where tiled on top of the floor tiles. We all take our chances but lets put it in to perspective and I hope no one uses the old extreme scenario here with babies having tiles fall on there head in the bath. We are sticking tiles not landing aeroplanes.

Hmmm. And how would you feel if your tiles collapsed on the wife whilst she was in the bath?? 😉 jooooookkkkke!!

Some days i wish!!

i have been thinking back over 30 plus years of tiling and have seen a few failures over the years but cant think of one where weight of the tiles was the cause of failure many over causes how about you

Never had it myself only ever heard of problems from adhesive reps.

well maybe a few reps could exsplain how they came to that conclosion .what were the signs how do you determan that wieght is the cause after ruling out other causes

When were the last weight limits written? I'm sure adhesive and material technology has come on a bit since then

The thing is the limits are set by the people that make the backgrounds and have nothing to do with the adhesive.

I am not convinced that a tile stuck to a wall is putting the same amount of stress on the background as one stuck to a ceiling. I can understand manufacturers need to put the limits in place to cover themselves but that dose not mean that if you go over by a few kg the background will automatically fail

Exactly right Dean, They have to give a figure for people to work to, but it will also have a tolerance to allow for people who will always go that extra bit, cos that's what people do, isn't it?

I refer back to my tyre analogy, where the tyre will not automatically burst/puncture at 50mph. It is a recommendation that you do not drive faster than that speed, but some people will.
