How do I hide old wall paper residue when painting?

Help! I need to repaint my master bedroom walls, post removing 30 year old grass cloth wall paper. Even after sanding, I can not get all of the glue residue bumps off. When doing a test painting area, the residue patterns show through. I am not a professional painter, so I need something easy to do. Thank you!
