What size notch for mosaics


I'm going to be installing tile around my fireplace. I have mosaic tiles (12"x12", but the mosaics aren't more than 3/4"). Anyways, I'm not sure what notch size to use so that I don't get too much thinset coming out. Any suggestions?
Thanks

There isn't just one good choice and it also depends on the thickness of the tiles. I would say an 1/8 square or 3/16x1/4 V would be fine. The amount of thin set left is also dependent on how you hold the trowel. You're gonna get mortar in the joints no matter what.

What kind of substrate are you going over and what thin set will you be using?

Jaz - MERRY CHRISTMAS to all.

I know I'm going to have mortar in the joints, I just want to avoid too much of it. I am installing these at a lowered hearth fireplace. The tiles on the floor are going to be placed on plywood. There are also existing tiles on the wall almost flush with the adjacent drywall. My plan is to just install the new mosaics right over the existing tiles. I'm thinking I may apply mesh tape to create some friction. Unless anyone has a better suggestion?? I'll just mix the thinset a bit thicker and use a fast setting thinset for the wall application.

Again, WHY?

Where on earth are you getting these ideas?

Over plywood because i want the tile to be flush with the hardwood floor in the family room. If I install a backer board, the tile will be higher than the wood flooring.

Over the existing tile because the existing tile is flush with the adjacent drywall. I'm trying to minimize the work, not because I'm lazy, but because I'm not sure if it's necessary.

As for the tape, I was just throwing that out there. Not sure its feasability, so nevermind about that.

Thanks

Tile on ply is a bad idea, x2 for a hearth. You need backer and do it right.

You want all areas to be the same height? Install the same flooring in all areas.
