Well thanks for all the helpful replies folks! This kinda job will probably be a one off. My little wet wheel cutter and straight cutter are fine for 99% of the kitchens and bathroom work i do.
I will suggest that he purchases some cement based adhesive, probably one part rapid flex bal and a 10mm notched trowel. Although the walls are quite good they do run out slightly in places. He will also need to hire a heavy dutter wet wheel cutter for cuts round the window etc.
Anything else anyone can think of so im definately prepared? As for grout we were going to use white ultracolor plus using 2mm grout lines.
Only for the dot and dabbed walls, it would be a good idea to second fix them with a decent size screw into whatever surface they are onto so as your not relying on the board addy to hold the board to the wall, can only help
If you use fixings don't break the surface paper or they will be next to useless and only fix where the dabs of adhesive are otherwise you could get a bow in the board
I was using it on the B&Q porcelain, but I got a handful of waste porcelain tiles from Topps where I bought it from and tried it on them as well.
And I managed to cut down the 600mm length as well.
The only difficulty I had was 45° cuts. I could score them and knock them on the rails but risked breaking the smaller piece. As I was tiling a wet room former I wanted to keep both pieces so the wet cutter was used here.
