Can I paint eggshell paint over satin?
You can apply eggshell paint over paint with a satin sheen. If you are painting walls, you will need to apply two coats of eggshell, or you will end up with a streaky finish. If you plan to paint wood trim coated with satin paint, you must abrade the satin finish to promote adhesion before you paint by sanding it with a 400-grit sandpaper.
