Removed wallpaper then painted. Noticed I didn’t removed all the glue. How do I fix uneven walls after I freshly painted the wall?
If your walls are without a texture then you will need to skim the affected areas with drywall mud, sand and repaint. If textured, orange peel or knockdown for example, all that you can do is apply more paint to fill in the affected areas. Skimming and retexuring a textured wall is difficult and best left to the pros.
