Not sure how I would tackle it, just pleased I don't have to.
😂
Can you get 'wide' angle bead? I.e. it's longer on one corner - about 6 inches long or something to drill into the inside alcove wall? Or would very long screws work? Or drill a strip of wood in place (2x2" or something the height of the wall?) to cover that corner and prep for some bead?
The area around the channels slopes up and down to it, much more than some sanding will do tbh. Something like the attached but worse and repeated four times over three walls.
PS. any idea what the strips of wood are for between the bricks?
