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