A friend and I were talking about filling raw particleboard edges so it can be painted, and he mentioned he prefers many coats of spray primer to wood filler, even though the primer doesn’t really level the surface, because he can’t get any wood filler to stick.
Does anybody have any recommendations for a wood filler that will stick to the very rough, crumbly, probably dusty edges of particleboard? We’re open to things like Bondo and drywall filler.
TIA!

I like Durham's Rock hard water putty. It cures fast. But it's an awful lot of moisture for particle board.
If I had to pick something for particle board it wouldn't be water based. Bonds would do it.
But I've never put paint or a finish on particle board. Even the faces don't finish well. Yuck.
I've used DAP Wallboard Joint Compound (from Lowes) for MDF; apply a thin coat and let dry. Too much and you'll be sanding it down forever. Worked well for my needs but not sure how that might work for particle board; perhaps worth a try. For painting, I used Zinsser cover stain (oil based), followed by a latex top coat or two. Again, worked for me but the rough particle board surface might be more of a challenge...
Mohawk makes an epoxy putty stick that is easy to use and it will not come out of the gaps. You can also mix up what you need so you're not wasting filler. Sands very well and takes all finishes.
I used epoxy to do such task, first I painted laminating resin to consolidate the rough edges and applied thickened coats of epoxy and sanded away the excess.
Got melt wood edge banding works fairly well. Can show a seam if you're not careful.
Pulled the metal stripping off an old bar table, sanded 1st to knock down the glaze then used Elmer's wood putty. Hasn't let me down yet.
Dynatron glazing & spot putty. If you want to paint it's a bit of a pain to cover due to the deep red, but it will NEVER crack.
If it is to be painted I would just use some shop made glue-size. Sands very smooth on PB, MDF, or ply and will let your primer control the surface texture. I keep a small jar at the ready near the sink. One of the times I use the sink each day I give it a shake to keep it ready to go.
Thanks, GeeDubBee! How do you make size? Which glue do you use?
