Hi Jean, hare are some more instructions on how to paint Formica. https://www.wikihow.com/Paint-Formica-Countertops
By using a good bonding primer, like this one, you can paint it. You simply need to primer it following directions on the can, then, once dry, just paint over that like you would any wall.

Rustolium has a great product for Formica countertops. I used it on 18 plus feet and the backsplash in my kitchen 10 years ago and it us just now needing a re-do. Follow the simple instructions, use a small foam roller and only apply one coat. EASY!
One drawback is that color choices are limited and solid colors only. But, I love that it took my kitchen counters from dull avocado green to a fresh soft cream.
