MDF Sealer

[rich]

What is a good way to seal MDF before the primer coat? I thought of using the two part exoxy sealer but can't find it local and it cost a bit. Thanks for any suggestions !

A widely used method is to use ordinary wood glue mixed 50/50 with water. Apply, let dry, sand if needed.

I use thinned body filler,it spreads on very smooth,fills larger voids and seams,hardens fast,sands very easy and very smooth. It is also pretty economical,a quart of body filler cost around $6 or $7 depending on the brand and a quart of body filler thinner(Plastik Honey) is around $10 and will do a lot of speakers. You can also buy a tube of single stage filler but it seams to crumble if not applied and spread very fast.You can get it at auto paint stores and parts stores. A.H.

I use BIN primer sealer (which is used for covering smoke damage after a fire). It worked well for me. It dries quickly, but smells pretty strong for half an hour..

Me too. Works nicely. Do a light sanding after and you'll be able to see any blemishes that may have been previously hidden too. It saves time and works well.
