Trowel for Mosaics

[Big Rick]

I tiled the floor in my ensuite/wetroom yesterday ( 600 x 400 slate set with Keraquick mixed with latex) I am going to do the mosaics today in the shower area and was wondering if I need to use a smaller notched trowel?
I used an 8mm for th ebulk of the floor but i fear if i use this in the 50x50 mosaics then loads of addy will come up through the joints?

Pointers please......

Im also gonna start the walls today - same large slate stuck with P9 so if theres anything on that to watch out for then......

Thanks All!

3-4mm trowel for mosaics

and just have a little step where they meet the main floor tiles - or i suppose I could "ramp it up"

Use this method http://www.tilersforums.com/tiling-forum/31764-mosaic-border-technique.html
You shouldnt have any "ramp"

same as Sir Ramic for me

Its the whole of the shower area floor that sgoing to be in mosaics - not just a strip though... (origional post not clear - sorry)
Area around 1.4 m2
is it a case of using a 4 or 6mm trowel - bedding up a bit where it meets the main floor tiles and just being really careful to clean all the gaps as i go??

what about a tanking membrane in the shower area Rick, this will take up some of the depth needed to pull your mosaics flush, (if I've visualised it right)

Hi guys - thanks for all the replys.

Doug - I've tanked the whole floor with tilesafe so doesnt do anything to make up the level difference,

My thinking at the moment is to use a 6mm trowel at 45 degrees - to give a bed of around 4mm overall - at the join between the mosaic and the larger tiles il just ramp it a little - dont think this will be a bad think as it will add to the fall of the "wet" area.

aah! I thought the mosaics were going on the wall along with floor grade tiles:lol:, ( the joys of reading posts when you have a 3 year old boy climbing on your shoulders:smilewinkgrin
