How Can I Make Paint Stick to Laminated MDF?
Asked by CraftyPineapple87
I bought a flat-pack cabinet from Home Depot made of smooth laminated MDF and used Bullseye 123 Primer followed by water-based paint. After applying two coats of everything, I've noticed white spots showing through and the paint peels off easily when scratched with a fingernail. I want to figure out the best way to ensure that paint adheres well to slick laminate surfaces, especially since I'm planning to paint some IKEA furniture next. Any advice?

To improve adhesion, you should definitely sand the surface lightly using 180-220 grit sandpaper before painting. That helps create a better texture for the primer to grab onto. Then, clean it up with acetone to remove any dust or oils. This should help prevent the issues you’re experiencing!

A bonding primer is key for this kind of surface. Make sure to scuff the laminated area first, as this will help the primer adhere properly. It's surprising how much of a difference that can make!

DIYNovice: I was in the same boat before! Sanding really changed the game for me, helped the paint stick better.
