Hello folks,
Think I've just dropped a clanger - be gentle with me. Just had a small bathroom re plastered - sand and cement on 3 walls and 1 plasterboarded partition wall. All skimmed with multi finish.
Just found out that we can't now use large porcelain tiles(600x300) on the walls cos of the weight restrictions on plaster finish! Unfortunately, we bought the tiles before we knew this (don't shout at me).
I bought tilemaster setaflex and bonding agent. What's the chances of the tiles falling off if I went ahead and Used them? Or is that just daft? (The tiles are 22kg per sq m) Or do I try to get a refund on the tiles? Any advice greatly appreciated.

It's simply not worth the risk. Get some 6mm marmox or similar. Make sure skim is dry, prime, fix boards with https://www.tilersforums.com/forums/tile-adhesive/ then mechanically fix into the solid walls and studwork.

As above, we can't advise to take the risk. It's a mechanical overboard with a backer board or exchange the tiles for some old fashioned lighter biscuit tiles I'm afraid :)

Not at all. Use the setaflex for boards and wedi washers to mechanically fix. Good luck

Yes, change of plan due to very helpful advice received(and much appreciated)
I'm going to use lighter tiles, and save the larger ones for the floor of another room that we need to do! Thanks again everybody for being so helpful.
