I am about to install a backsplash using marble & glass mosaic strips, mapei Type1 mastic and some Schluter aluminum edging strip to hide the exposed parts of the outside permiter of the tile.
My tile is 5/16" thick and I bought a 3/8" depth edging strip. I do not want the edging strip to be higher than the tile surface in the finished job. Since I am applying the mastic with a 1/8" trowel, then I guess the mastic will squeeze down to 1/16" after I put on the tiles?
What do people think? Should I move up to a 3/16" trowel? I just don't know how thick the mastic will be after it's been squished down and has set.
On the other hand, I could buy a 5/16" edging strip and then I would know for sure that the tile will stick out past the strip. But if I can make a perfect job with the 3/8" strip then that is the better solution.
It's all a matter of knowing how much thickness the mastic will contribute.
