Hello everyone,
I wanted to repaint a 4-year-old drywall in the nursery, which is white, to refresh the color. Before I started, there were no issues! Now I have painted the wall three times, but I still can't get rid of the strong streaks. On closer inspection, I noticed that part of the wall can be painted flawlessly from floor to ceiling, while the rest cannot: here, there are not only streaks but the surface texture is different and rough.
Could this be a defect? Could the builder have done a poor job here? Perhaps they didn’t fill, sand, prime, or something similar?
Does anyone have an idea what might be wrong with the wall and why it shows such strong streaks?
In the picture, you can see that the right half is clean. However, the left side is completely covered with stains from floor to ceiling. These also do not disappear when painted over.
Best regards
Sergio

The cause seems to be moisture here. How long has it been since the paint was applied in the photo?
Maybe it's also related to the paint. I can't identify a workmanship defect from this. It looks like everything is too damp.
You might want to measure the humidity in the room and heat it properly.
If the stains do not dry out, apply a primer before repainting. Then paint again. Moisture probably isn't the issue. It seems rather too dry. Also, part of the wall is free of streaks. Furthermore, the stained part of the wall is rough, as if it hasn’t been smoothed or polished.
