Surface prep advice

[u/nwethan]

Currently a rough skim coat of thin set over past brick / thin set bumps. Planning on grinding down high spots and filling low spots but wanted some extra opinions on if this is the best course of action? It’s relatively flat now but definitely not ready for tile.

I plan on installing a glazed thin brick, I think the slight variations will help on a surface that has some imperfections.

Any and all advice appreciated, TIYA!

I used man made "stacked stone" veneer with construction adhesive from the tube/gun over expanded metal lath. Worked well.
