A shovel?

12mm trowel isn’t gonna cut it for those tiles. Assuming the floor is spot on and the stone is calibrated, Something like a 10mm on the floor and 10mm on the back of the tile also.

I would personally use 12mm floor and 8mm on tile.

@Lakey ... I assume you were going to use the trowel for adhesive on the back of the tile too?

Any more suggestions - 15mm on floor and 5mm on back of tile?

I’d probably cut my own trowel to 16mm for floor and use a 4mm mosaic notch on the back of the tile, and always spread from left to right, not right to left

Brickies trowel 6 dots .

I would use a 12mm square trowel and back butter the stone.

Thanks for all your input.
I have varied from
12mm on the floor 6mm on tile to
12mm on the floor 12mm on tile as the stone isn't calibrated so varis by 4mm in thickness.
I'll post some pics when i'm done
