Wall painting problem. White paint does not absorb

2020-10-11 23:09:09

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

Hi,
I'm not a painting expert, but primer is usually used on a "bare wall."
If your main problem is the paint roller slipping, try a more expensive model. I had the same problem with those cheap rollers from the home improvement store. Then I bought a mid-range roller from a specialty store for €20, and the difference was like night and day.
If you're concerned about coverage, I only see spots. Try painting the entire wall and let it dry.
By the way, Alpina is a bad paint; only the one with the cat on it is somewhat okay.
A "professional" paint would be better, they cost a bit more but usually save you 1-2 coats.

Whether light on dark or dark on light. From my point of view, it always looks blotchy at first. After the first coat dries, it gets significantly better, but you can still see some color showing through in places. After the second coat dries, that's gone. Maybe the painter can do it with professional paint in one go. The risk I see is that as a layperson you still have to paint twice despite the professional paint being twice as expensive. Then the mid-priced paint would have done just as well.

I agree with M4rvin. First, paint the entire wall. There are certainly big differences in rollers as well. It can also be an application error if it doesn’t roll smoothly. (too much paint, roller not properly covered with paint, etc.)

From the description, it also reads as if the old paint is too smooth. For example, latex paint. A professional could really help. Or rather, one actually has to see on site what is going on.

I also suspect that the wrong paint (dispersion?) is applied on the wrong base (oil paint, latex paint).

Of course, it can also be a user error if it doesn’t roll properly. (too much paint, roller not properly covered with paint, etc.)
