I'm laying 6x6 1/4" thick tile for the majority of my tub. Halfway up though, I'm putting a 3" high strip of 1/8" thick glass tile inlay around the interior of the tub. This is the type of tile that comes on the 1'x1' sheets and each tile is 1" sq.
Because I have to build up the thinset to get it to level with the 6x6, i'm having problems getting the glass tile to set-in without moving around. I'd like to cut a 3" strip of backboard and put it behind the glass, but I can't find one thin enough.
Any ideas?
Thanks, D
