:lol: yehhhh that is cool, apart from , you lift heavy stone :lol:. Will be posting about this project , for next few months. I hope membersd like jonnyc will comment. Hope will get some advice as well
tony , both these projects in pools and used glacier stone supplied from stoneage .
one real problem apart from the fact that i was asked to start full stone off the bottom and then glass company came round fitted glass central so out of balance!!!
but the other was that even though using a tight joint and mixing colour combinations of grout, this till shows up really badly when you look at feature wall from distance.
i used stainstop in a bottle and sprayed tiles and joints double but you still see that definition.
we used a cake icing piper and then adapted to just gun the grout in to joint without any overspill but still dissapointed with end result after so much effort.
i think in retrospect on both walls being only features we should have not grouted at all.
incidentally we mechanically fixed exactly same way as you showed except we had two fixings top and bottom.
you dont need fandango fixings unless you are being worried about being sued!!!
