Mosaic Adhesive Bed

[skymole]

Hi I am about to tile a shower area with 23 x 23 x 10mm mosaic. It is a walk in shower area with partitions which will be glazed.
The problem is that in order for the sides to line through flush with the end and finish on a full tile I will need a 4-5mm adhesive bed. This is of course way too much.

The only solution I can think of is to build out the thickness of the partitions using a thin tile backer board.
If I do this I will be able to leave the right dimensions for the adhesive bed.

What would people recommend for thickness of adhesive and which trowel to use? Should I have a slightly thicker bed on the floor?
Or does anyone have any other suggestions as to how to tackle this problem.

I have attached a photo and illustration

Thanks very much for your help
Best Regards

You can get 3mm / 4mm wedi boards now I believe.

Yep I've come across 4mm didnt know you could get 3mm! What would you recommend as a trowel and adhesive bed for the mosaic on the wall?

Wasn;t sure if it was 3mm or 4mm but as you have come across it then ye it must be 4mm lol lol..

You can use a 3mm mosaic trowel.. this will bed to 1mm approx..

Depending on the thickness of the mosaic, standard 3mm but if there 7mm thick mosaic then a 4mm..

Thanks very much for your comments and interest, and of course I will be happy to provide photo's if they would be of interest - I actually have photo's going back a way..
..So just to confirm - on a 10mm mosaic would you recommend a 4mm trowel?

Thanks again
