Hi Brett, welcome. Silicone will work well in that gap. What are you going to use as a barrier? Is there poly or felt behind the CBU? If not, you may want to apply Redgard over the CBU.

I usually use sanded grout with glass tiles, even with the small joints. The sanded grout will force into the joints okay.


It's up to you on the tile done with mastic. If it's on a wall that's down near the bottom, I'd take it all out.
