Is it possible to paint over cheap glossy mdf kitchen units?
Sure… you can paint over them! Here are the steps you’ll need to take to make sure the paint sticks well: 1. Wash the units with liquid TSP to remove all grease and grime that will keep the paint from sticking properly. You can find liquid TSP at any good home hardware store. Use the liquid instead of the powder, as the powder is toxic, it’s harder to mix and you have to rinse it after. Let it dry and then lightly (no need to get sore arms, I promise!) sand with a fine grain sandpaper just to make all smooth. Wipe off the dust with a soft, damp cloth. Let dry. 2. Use an oil-based primer to prime the units. I suggest either Bull’s Eye 1-2-3 or Kilz or any other good quality oil primer. It’s important not to use a latex (water based) primer on the units since you don’t know what kind of paint is on them right now. If it’s oil or emulsion and you use latex, the paint will easily peel, scratch and chip off. Allow the oil primer to completely dry according to the directions on the can. 3.
