How?
There used to be tiles as a backsplash, but I want this wall now to be smooth and single-colored, since the number of upper cabinets has been reduced from fully covering the wall to just two.
My question is how to best smooth out the old wall from the old adhesive and the resulting holes in the plaster? For example, using an orbital or belt sander? Admittedly, the orbital sander is a bit too small for this task and its design can cause unevenness on the - new - wall. However, it has proven effective for sanding rust on cars in hard-to-reach spots.
But I only need the tools for this one-time job, so I don’t want to buy anything expensive just for this!
Also, what is best to use to level the differences between the old plastered part and the old but unplastered part as simply as possible? Plaster? Filler? Which tools?
In the end, the whole surface should be the same red color as shown on the plan.
That would be the wall on the left in the plan.

It’s no longer an issue since I installed a drywall partition with a 50mm (2 inch) stud width in front.Yes, that’s the way to do it.
Because the approach you were considering would have involved a lot more work.
