Yeah for sure it's just wrong isn't it so its one or the other, mechanically board over to existing stud work with 12.5mm plasterboard or remove existing skimmed board and fix new 12.5mm board to the studwork.........ill put these options across and if he still wants to go onto the plaster then it will have to be another fixer......
I'd want back to stud and 12mm nmp but seems as though the customer is being difficult already. You're doing the right thing standing your ground pal
 
Yeah nmp even better but then there is the price compared to plasterboard......already asking lots of questions on labour/material costs today..........maybe I should just quote him an absolute fortune to get the hell out of this truly terrible installation!!!!!aaaaaaargh!
 
Hi Ray,

Yes they will be fixed with s2 addy clamped and pinned, so what's your substrate prep here mate.....before fixing????

Cheers
if your pinning and clamping like you would marble slabs then the weight of the tile is mechanically fixed to the wall. I used to do marble slabs years ago and the methods we used then would apply to this product. s2 addy would hold the slab but the weight is in the mechanical fixing so weight doesn't become an issue on the plaster. fix the clamp into the joists easy peasy.
 
Does the clamp show through onto the front of the tile / slab? I guess its like a little grabby hook thing?

you can not fix these tiles like you would normal tiles.
drill small holes into the sides and top of the tiles about 15mm in depth then you drop the pins in so the slabs alline up then another two holes into the top in front of the joists were u drop in your clamp then screw to the joist tile fixed. repeat on the next till all fixed. that's how we did it in the 80s

crikey Ray,

Sounds technical!......I'm not sure the fixing method is the same as the marble slabs you have worked on......it seems the clamps with these decorative concrete slabs sit in all the horizontal joints and create the exact joint size.....there is no technical Enquiry line on the company website, I have just spoken to the distributor who is the only contact I can get hold of, I have a drawing and a little bit on fixing guide......as follows......all the info and pics I have.......
