Ginny....I believe I would scuff up a bit with sandpaper, apply primer then paint.
Clean with TSP. Lightly sand. Prime and paint with oil based primer and paint.
You could also use chalkpaint, which requires no primer. good luck!
Hi, You could use ESP (Easy Surface Preparation) on first (sort of paint) then paint on top as required. Can be used on top of even Formica...............
