I would like to hear about your experiences working with MDF. How does it machine? How does it hold paint? Any information will be helpful. Thanks.

I agree with Joe. It is terrific stuff with perhaps an exception or two. My only real complaint is that it has a tendancy to swell not only when it's been wet but also under damp conditions. If it were me I would be carefull to finish it on ALL sides if humidity is a possibility. As for the nailing problem I have had some considerable success with 18 guage brads from a Bostich or Paslode nailer when nailing on the edge of MDF. For what it's worth.

*We used MDF quite often until my sinuses were about to give out. I second Steve and Joe. Watch your nailing / raising of the material at nail heads. I have had some success using it for curved details intended to look like drywall / plaster.LOOK INTO LIGHT WEIGHT MDF> I hear it is 1/3 the weight of reg. MDF.

I love the stuff(dust excepted). I try not to nail it, except to hold it while glue dries. Wonderful paint surface; you might also consider laquering raw MDF. Very post-modern, hip look. I've seen some things done like this and they look great if you like "contemporary". Even if you don't, it's avery versatile material. You can't judge it by those thin lumberyard casings.

What do you recommend for sealing the edges prior to painting. I am currently using a solvent based primer(Kilz). Just seems to wick in. I eventually get the ends sealed but it takes several coats.

I use a paste wood filler (NOT wood putty) on all milled edges. Sand smooth, then a light coat of filler. When dry, a light scuff sand, then oil prime and subsequent top coat.
*I'm waiting for a call back regarding the lightweight. . Can't wait! I believe it's 1/3 lighter than the regular stuff, 60ish pounds vs 90ish pounds.

Sherwin Williams has a very reasonably priced filler that has the benefit of drying quickly (30 min.)
