Mosiac tile on uneven wall

My wife wants a mosaic tile installed on the kitchen walls above the backsplash. However, our kitchen backsplash has some areas where it doesn’t sit flush against the wall (drywall issue?). The gap in the attached photo is ˝” wide.

The tiles she selected are 4mm thick with a mesh backing. Do I need to use leveling compound before the thinset adhesive? Would you use a border trim piece between the existing backsplash (top) and the tile? Just curious here. I want to know what I’m doing before tearing into another project!

Thanks in advance!

No, I would not try to level the wall. I would install the back splash tile and grout then caulk the gap where it meets your counter. Whether or not you choose a border detail around the back splash is your decision based on aesthetics.

You have 4mm tile plus mortar but some 12.7mm gaps meaning your going to see a gap between the new tile and the back splash.

Personally I'd be looking for a flat tile to lay across the top of the back splash, maybe something with a bull nose, that will cover the gap with the tile sitting on that.

You could use a pencil liner across the bottom to bridge the gap and then start your mosaic on top of that.
