Installing Mosaic Glass tiles

[Tim Wagner]

I am putting this particular tile behind the sink. 6" high, and back to the window 3". I am also doing tumbeld limestone tiles for the rest of the backsplash. all of this is being applied to painted drywall, and unpainted where I had to patch some spots.

As for the glass tiles, I am using a adheisive (acrylic based) called Omnigrip, after the forth day (today) of drying there is still some movement in the tiles. Is this due to the type of glue i am using? I can't have them moving all the time or when the grout goes in it will crack due to movement. should I give it more time to set, or strip it off and try something differant?

TIA,

I bet you have slump from a really slow set up time.

For glass I'd be using an epoxy. There are epoxies just for glass tiles. Most I have seen in the tiling business have a silica grit you mix in. It makes it really thick but it takes none of the slump out of the epoxy. I didn't like the one I used to apply marble tiles because it remained slump-able over a period of several hours. If I it again I'd get a faster setting and maybe a gel epoxy.
