Use a putty knife or a paint scraper to remove the peeling and cracked paint. Sand the surface with a 100-grit sanding sponge. Switch to a 220-grit sanding sponge to finish off with a very smooth surface.
Cover any areas you do not want to get paint splatters on with a plastic dust sheet. Apply a layer of latex primer paint with a paintbrush. Allow 2 or 3 hours for the primer coat to dry.
Apply two coats of semigloss interior paint if you are painting an inside windowsill. Use a semigloss exterior paint for an outside windowsill. Allow a few days for the paint to dry and cure.
