Hello!
I was going to put up a grid in my daughter's room (the kind you can hang things on) and started drilling carefully without a hammer drill first, so the holes wouldn't be too large. Then I drilled with a hammer drill, and the paint around the drill hole started to peel off in large flakes of 1-2 cm. It looks very unsightly.
In the second picture, I've filled around the hole, I guess I'll fix it with some paint later.
How do you avoid results like this?
