Ok...so I won't bore you with the too-numerous-to-mention expert's
opinions who advise priming MDF before painting. I'm surprised you've
had ANY luck with painting MDF without a primer. But hey, I'm sure
there's plenty more things I don't understand! g

i have to paint some MDF but ran out of primer. Has anyone painted MDF
without
primer, and if so, does it make a huge difference?



I have never primed MDF before painting. I have a customer that buys houses
restores the kitchens and sells the houses. I rebuild the kitchen drawers
and door fronts out of MDF and he sprays them with out primer. They look
fine to me. That said however he does spray several coats. I only put on
one coat when painting with a brush.
I suggest that you try it on a few scraps to see if the difference will be
significant enough to warrant priming the rest of the job.
