Exceeding substrate weight limits.

[White Room]

I just did a quick search and managed to find this post by Oli, which lists the weight limits. It was a few years ago but still relevant...

The float and set should be 20kg not 28kg....IMO

Not walking, running.......

Well the builder never got back to me yesterday as he said he would ,was just a waste of time driving 40 miles to look at the job and he did not have the respect to let me know,maybe its what I said to him that he didnt like ,well I hope it all goes bandy for him,as I'am sure it will with that much ply on the walls.

Afternoon all,

Got some 600x300 Basaltina Black Porcelain going up to the ceiling in an entire ensuite, Tile Giants guys reckon tiles weigh in at about 22kg/m2. Walls all plasterboard and would think have been skimmed. Started ringing a few bells for me, but from what I've established it's very close to being ok, what's every bodies thoughts. I could quote to 12mm Hardie the whole room but don't want to give them this expense if they don't need it.

Cheers RR
