Weight limit on painted plasterboard

[Dumbo]

To my mind on a skimmed wall you would need mechanical back up or else you just as well tile straight onto the skim .
By the way any body considered how horrible some of this work is going to be to take apart when someone wants to change their Tiles

How can something like that be so different ??
It does make sense, can some one find out ?

What makes sense?
Temp fixings?
Safer to leave them in.
Personally wouldn't fix boards to a wall without them.

It makes sense to me that it spreads the tile load out when you stick a board on, I don't do over boarding etc but it's something I'm interested in offering.

Take the plasterboard down and replace it with new. Would this be the easiest and cheapest option?
