What do I use to reattach glass mosaic tiles?

Q. I have installed a stained glass wall and pond. The mosaic sits on a mortar base, redguard sealer, then more mortar to level the surface. The glass mosaic is put up with latacrete. All of this is put on to a 8 x 16 block wall. One side is peeling off the wall and the glass is cracking. What do I use to reattach the glass saic? Thanks for your help!

A. Glass will not bond with standard setting mortars. You need to use an expoxy setting mortar. Look for a company that has mortars for glass tile.

Best of luck!
