Chalkboard paint while expensive goes a long ways. I bought the little jar $22 and it took less then a quarter to do the fridge 3 coats. First step was to wash the fridge door very well then sand it with some steel wool or very ruff sand paper - some tutorials will recommend priming with the magnetic paint first I didnt and the magnets still stick. . Then paint it......wait for it to dry for ruffly 4 hours repaint, and then one more coat! I let mine sit for 3 days like it says to before I "cured" it with chalk and now my kids are having a great time writing on it. May still paint the handle and the bottom part one day.
