Default Sk5000 (new construction)

Do you like it? I do but my only drawback has been mdf(raw) and closets(new construction). I rattle can MDF shelving and benches with Bin, sand, dust and finish coat twice, or aqua lock and 1 coat finish. It seems to raise the grain a lot causing it to be rough. Anyone else experience this issue? Also closets I prime with pva, sand after and spray 1 coat sk5000 semigloss, they come out rough also and I have to sand them again and finish coat, then they are smooth.

MDF and raw wood, prime with lenmar 1WB.200. Doesn't raise grain and sands to powder 20-30minutes. About 1/2 the price of BIN too. Spray only though.



SK5000 acrylic/alkyd (203/204). Really great product for the price ~$28/gal

or CabinetCoat. CabinetCoat cures much faster and has better coverage than SK5000 but cost almost double.



BTW Dont bother with PVA, use SuperSpec253. Cost more but will save you hours of headaches.

I was going to post a question asking about this MDF crap, weird. Anyway, I'm finishing up a 500k home with columns that are made of MDF and I think they're a PITA. They don't prep well, meaning the nail holes are very hard to make look good. We sprayed on several coats of SW Pro Classic in semi gloss and the nail holes tend to tattletale.

I've been in this business a long time, it seems this MDF is more popular than before. There's a learning curve on it.

you really have to use a lacquer or alkyd based primer on this new mdf crap. Anything else cause all kinds of problems. I did a test in the hillbilly paint lab a couple of years ago and the only products that didn't cause microbubbles or raise the grain were lacquers, true oil, or shellac based. It's another case of them finding a cheaper way to make a substrate without any regards to how much trouble it will be to make it look good.

They have been using unfinished MDF for closet shelving for at least 20 years in my area. And of course the pre primed for trim for much longer. I don't like it, it chips much easier than wood.

BM Alkyd Enamel Underbody is about the best primer for raw MDF that I have found.

I haven't tested that product but i'd have to agree that it would be an excellent choice.
