Hello,
I am painting the walls of my apartment. The old paint is dark, and I want to paint it white now. I am using white paint from Alpina.
The paint does not absorb well into the walls.
When I apply the white paint, the roller slips on the wall, and the old paint is still visible after painting.
Should I paint 2 or 3 coats?
Or do I need to use a primer first (see in picture 2)?
How can I repaint my walls?

Hi,
I’m not a painting expert, but primer is generally used on a “bare wall.”
If your main issue is the paint roller slipping, try using a higher-quality model. I had the same problem with cheap rollers from home improvement stores. Then I bought a mid-range roller from a specialized store for about 20€—the difference was like night and day.
If your concern is coverage, I only see spots. Try painting the entire wall and let it dry.
By the way, Alpina paint is not very good; only the one with the cat logo is somewhat acceptable.
A “professional” quality paint would be better—it costs a bit more but usually saves you from having to apply one or two extra coats.

Whether light on dark or dark on light, in my opinion, it always looks blotchy at first. After the first coat has dried, it looks much better, but you can still see some areas where the color shows through. Once the second coat is dry, that disappears.

Maybe a professional painter using high-quality paint can get it done in one coat. The risk I see is that, even with the professional-grade paint that costs twice as much, an amateur might still need to apply two coats. In that case, a mid-range paint would have been sufficient.

I agree with M4rvin. First, paint the entire wall. There are certainly big differences in rollers as well.

Of course, it could also be user error if the paint doesn’t apply smoothly (too much paint, roller not properly loaded with paint, etc.).

From the description, it also sounds like the old paint layer might be too smooth—such as latex paint, for example. A professional could really help. Actually, it is necessary to inspect the situation on site to understand what is going on.

I also suspect that the wrong type of paint (emulsion?) is being applied over the wrong base (oil-based paint, latex paint).

I agree with M4rvin. Just paint the entire wall first. There are definitely big differences between rollers as well.
