Tiling Tips: Is there a weight limit when tiling a wall?

[ythan]

kitchen tiles are porcelain 10mm thick, and include one 4.4m long wall, 3.2m floor to ceiling.

And the weight per square metre is...............

 

[ythan]

about 25kg/msq plus addy

Is this formula of 20kg a meter on skimmed walls using a sledge hammer to crack a nut?

I can see the reasoning behind the post by ythan above in as much as the force would be downwards and not sideways.

Has anybody ever seen tiles fall of the wall due to weight issues, tiles that have been adhered properly with a suitable adhesive?

This is a job I tiled and was plastered by a plasterer, not me I might add, I pulled off a tile because it was'nt sitting right and pulled off the skim coat.
It depends how good the plastering is.

thanks for the photo, whitebeam. yes, looks like poor plastering - the skim coat looks very thick. Probably even thin tiles would have had a problem here.

i think the photo illustrates the need to check out the plaster for soundness, maybe even do a trial tile fixing to check the plaster. i still think the normally adopted weight rules are over restrictive and can result in a lot of unnecessary cost & work.

the weight rules don't stop problems with poor plastering.

Beam did you have to call a plasterer in?

No Pete, I had to sort it out:smilewinkgrin:

 

[ythan]

be very interested to learn how you sorted it out.

All the tiles had to be ripped off, the only good thing is the tiles had only just been fixed so the easily removed.

All loose areas of plaster had to be removed and tiles cleaned, the room looked like a bomb site and I spent about 2 hours cleaning up, the customer was'nt impressed.

Pva and reskimmed where was required and left to dry, job delayed waiting plaster to dry out.
