HI

I have a fully marmoxed wetroom to tile with 600x600x10mm porc. tile wall and floor (with keyed back) and 50x50x8mm single tile glass mosaic strip, full height verticle in the shower area. So two questions.

1. Which trowel to use to ensure a full bed for the shower walls (could I just use the 20mmx10mm round notch I am going to use for the floor - to much ady!) or should I invest in a BAL thin bed Solid bed trowel?

2. To get 100% cover behind the mosaic and leave them flush with the face of the large tiles what would be the best way to lay them?
Lay large tiles , leave 55mm gaps them use a margin trowel to lay the ady depth required???
Never layed mosaic in wetroom, so unsure of best practise.

other trowels already in my bag are
Bal Solid bed tipped trowel
10mm and 6mm Square notch

10x10 round notch trowel and back skim each tile to gain a solid fix..

As for the mosaics, then use the Dog tooth method... use the search feature to see others threads/pics on how to do that.
