I am doing a en suite refit for a neighbour and the top of the tiles are
going to be two rows of glass mosaics (1 inch square on a net). How do you
stick these things successfully? I have tried putting a thin layer of
adhesive on the wall and then applying the tiles but that wasn't enough
adhesive. If I put a layer of notched adhesive on then it all sqidges out
between the mosaics! What's the trick/answer? I am only really concerned
with the shower area really as the mosaic rows will be at shoulder height
and I would like to get a good amount of grout in the gaps, elsewhere in the
room I am not too concerned as long as I can get at least a layer of grout
in as these tiles will not get wet on a regular basis.
If have only done borders where there are tiles above and below. I
leave a gap for the mosaics
and do them later. Making *very* sure the gap is correct ! In your case
I would put up a temporary batten since there is no row of tiles above.
I then put a solid bed of adhesive at just the right depth (using a
home-brewed tool that rests of the above-and-below tiles) so that when
the mosiacs are pressed down flush with the other files, it "just"
squidges - this helps them to fix them securely. I have seen far too
many "professional" jobs where the mosaics are obviously thinner than
the tiles, and end up recessed below the surrounding tiles.
But I always need to scrape out the gaps to some extent - since I agree
with you the grout must be a good depth if these are to be waterproof.
