Don't forget PJ to post pics of the work as you go so the guys can give advice, just think you nearly PVA'd the walls so it was a good thing you came on here.
PVA is for plasterers and has no place in the tiling world.
I was intending to buy a cutter. Looks like the Rubi TX-700-N is the one to go for? How does the TX-700 (no N) differ to the TX-700-N? Is the N worth the extra?
I'm gonna have to buy the cutter tomorrow at the lastest, along with the (10mm) notched trowel, grout trowel, knee pads, etc, etc, etc.
