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.
TIA
John
