Tile weight advice

[robbieraven]

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

Hummmmm on further reading 20kg/m2 on skimmed plasterboard so I reckon I need to re-board this or chose lighter tiles. Turns out the tiles are closer to 24kg/m2 too!
