Hello-
I built soffits in my basement using MDF. All the cut edges of the
MDF are either inside unexposed joints or are covered up by pre-primed
moulding.

Can I prime the smooth outer surfaces of the MDF with just regular old
PVA primer before I paint or is there something special that should be
used with MDF?

My plan is to prime with PVA and then applya white latex paint. I
plan on using an airless sprayer.

Thanks for any feedback...
