Used Oil Based Primer on MDF - What kind of paint should I use?

3102 Views 3 Replies 4 Participants Last post by  Red Dog
I made a component rack out of MDF and I put 3 layers of primer on it (Kilz Oil Based) and I now want to paint it black.

What level of sand paper should I run the Orbital Sander on the last layer of Oil Based primer that I used?

Also, what kind of paint should I use as far as oil based or "primer and paint all in one" or "water based" (I want to paint it black and I am going to use Cigar Foam paint rollers to paint it black)??

I think you overKILZed with the primer. One coat of primer is usually sufficient. The orbital might be a bit too aggressive for sanding. Use a 1/4 sheet palm sander with 220 grit. You can use oil or latex paint for your topcoats. As far as the foam roller, I am not a fan. It holds very little paint and will leave skid marks in your finish if you're not careful. A Whizz roller with a mohair roller sleeve leaves a nice finish. You can also use a regular Whizz roller sleeve, because the mohair can act a lot like the foam holds very little paint.
