Experiences with spot touch-up of wall paint?

Dear experts,

I am in the process of spot-repairing the interior of a 6-year-old house. Playing children have left some stubborn stains and damaged some edges (plaster chipped off over the corner profiles).

I observed the technique of a professional who had done touch-ups as part of the 5-year warranty. He always worked with a roller and not a brush, and he didn’t just touch up a small spot on the unsightly areas, but also rolled generously with a fairly dry roller into the clean parts of the wall to avoid a hard edge. Is this also sensible?

I have purchased the same high-quality white paint (70 EUR/10 liters, brand quality), very high-quality rollers, and other accessories, etc. Nevertheless, the repaired spots are still visible, although only when looked at closely.

I do not want to paint the entire wall, only spot-repair. Are there any further professional tips to make the transitions even less visible? I rubbed the transitions longer with the palm of my hand, and that already helped quite a bit. Surely there are better tricks than rubbing with the hand? Maybe with fine sandpaper or a cloth? Or with water?

I am curious what I can learn from the experiences of the professionals.

Best regards

No, it hardly works because the old paint changes with the room climate and the people in the tone. And since strangers have lived there, I would have the urge to paint over everything - even if only for the sake of well-being.

Thank you for your feedback. And no, you must have misunderstood. I built/bought it myself and by now it is 6 years old. A year ago, a professional had already done some touch-ups and it looked great, but the kids unfortunately keep causing damage again and again. Especially now with Corona when everyone is playing at home from morning till night. Here a bad stain, there a damage on the corner profile. And I can't repaint everything completely every year. That’s why I’m looking for tips on how to do the repairs.

With eraser sponges you can tackle white walls and remove stains. But don't overdo it, otherwise you remove too much paint.

The rocket built from wood itself launched totally cool in the living room and shortly after the wall looks like this because of an emergency landing...



I can't call a painter every time because of something like this or paint the entire wall. And with kids at home during Corona, I can't always scold them when something goes wrong. That's why I like to regularly touch it up and keep it in top condition.

Great thing with the eraser sponges, I do that regularly too. But I'm looking for tips on how to fade the transition from the repair to the rest of the wall. Doing it by hand worked quite well, it also darkened the new paint a bit. But there must be an even better method or trick?
