Paint MDF?

Is it possible to paint MDF without it looking all blotchy? I was told just a few layers of filler primer, block it, then another coat and spray it. I hear it absorbs paint and makes it look blotchy. So what about putting down a wood sealer first? Then block it, prime, and paint? Is there any goo ways to do it and have it turn out decent?

Yea, just putting filler primer over it and trying to paint it wont work to well for you.

What ive allways done in the past on the backs of sub enclosures, is sand all the edges smooth and then saturate the MDF with fiberglass resen, it will soak into the MDF and give you alittle bit more of a foundation to work with.

Ive done it with about 3 coats of the fiberglass resen, and it worked great, i was able to hit it with a DA, and spray primer and paint it.

Hope that helps

well we just did a few(a bunch) of pieces for a m3 we have in the shop and that is exactly what we did. used the mdf for the molds and bondo'ed for contour and used filler primer(sem brand, in a spray can) sanded until it was to the installer liking then too it to the paint shop... got it back today and the pieces look great. i'll try to get some pics up tomorrow.... and check out the shops website.... www.audiodesignsofatlanta.com

those guys discuss this daily for some reason

If you sand the MDF and spray several coats of primer the wood will quit sucking up the primer if you let it dry good between coats. It saves you the time of sanding all of that fiberglass. This only good on interior pieces if its going out side the truck you need to glass it. Its always worked for me.

Conflicting answers. Lol. I'd like to see pics of both.

Thats good to know. It will be staying behind the seat. And I'm not looking for shear perfection, just something nice enough to look at the few times the seat gets tilted forward.

y not use kilz wood primer then paint over that

Isn't that brush on? I don't want to see brush strokes.

Ive used primers to try to saturate the wood, the best way is to either soak it in resin, or just wrap it because it will look better wraped anyway. Most painted enclosures look like crap to me, they are ususally wavy as the ocean. You could wrap it in some potato sacks.
