Hi I’m going a mirror and frame mosaic for my sisters’ birthday. I have got some ply and glued my mirror to it, now I want to mosaic a border around the edge. I have a 3cm border of ply to cover with tiles. I have lots of 1cm x 1cm vitreous glass tiles to use.
I was going to ‘butt’ them up against each other so I have no gap (using no-nails glue so it’s a strong fix as doesn’t need to be weather proof should be ok) but I was told I have to grout them, if I do I’ll only have 2 tiles and a lot of grout between as I cant fit all 3 and the grout on the border I have. Do I have to grout them or can I just grout around the edge of the frame to make it tidier?
Thanks. I’ve primed the ply first (scored and covered with a PVA&water mix) the no nails works really well. It’s going on a living room wall so should be ok, well away from damp air.
Is there anything i can coat it with to protect it from dirt etc other than grout?
