How to fix uneven walls that are painted?
Hi, long story short - none of the walls are even, they are messed up but could be easily fixed and evened if they didn't have paint on it (I'm guessing that the patching compound just won't stick and stay to the paint), and getting the paint off will take ages if it is possible at all. Also the corners are messed up and looking ugly.
Any ideas how to do it? I'll add some pictures below.

Do you know what type of paint is on the wall? .. http://www.doityourself.com/forum/pa...latex-oil.html
Usually all you have to do is scuff sand the paint with 80-100 grit and then apply the joint compound.

Oil base enamel does complicate things. While I'm not afraid to apply j/c over small sanded areas of oil enamel - I would not skim large areas without first either aggressively sanding with 80 grit or scuff sand followed by a solvent based primer.
is there any danger that the enamel is lead based? It's not a good idea to sand lead based coatings! You didn't state where you are located and while lead based paints have been banned from residential use in the states since the mid 70's it's still something that has to get dealt with from time to time.

Would j/c stay on the walls without the oil based primer but only by sanding it with ~80? I have somekind of transparent liquid primer that I used on walls and ceilings before wallpapering/painting them - would that kind of primer work?
I'm located in Europe, not sure what is a lead paint - last time the walls have been painted was about 8 years ago.

Lead based paints were pretty much the norm 50 yrs and longer ago. In some ways it was superior to modern day oil base paints but lead is hazardous to your health! both from breathing the dust created by sanding and from ingesting chips. It might be a good idea to check with your local paint store [not a paint dept] to find out local info regarding lead based coatings.
The liquid primer you are referring to sounds a lot like Zinnser's Gardz. It is a latex primer formulated especially for painting over wallpaper adhesive that can't be removed. While it's a good sealer I don't know how well it adheres to oil base enamel.
I wouldn't be afraid to apply j/c over enamel paint sanded with 80 grit, I would not skim coat the entire wall over enamel without applying a primer first. It's ok to apply a thin layer of mud here and there over the existing enamel.
