Re: Finishing with BLO
Mike Schwing from Md.
>One of my favorite finishes (but for some reason I haven't used it much late) involves BLO, shellac, and varnish. One coat of BLO will usually do just fine for this. I apply it to the sanded surface, let it soak in for 10 minutes or so and then wipe as much of it off as I am able. Let it dry overnight (I have skipped this step with good results also), then brush on a coat of Zissner Bullseye Shellac from the can (Blonde, not amber). When dry sand it smooth with 320 grit, and then apply 3 thin wiping coats of General Finishes Arm-R-Seal. Finally, rub it out with 4/0 steel wool and a beeswax/orange or lemon oil mix. It will make a really, really nice, tough finish.
The shellac seals in the BLO - and keeps it from reacting with any other finishes. You can topcoat it with anything after the shellac. The Zissner product works well for me because of its long shelf life and if you wanted that to be the final finish it surely would be a nice, hard finish, several coats would build very nicely. I like the arm-r-seal because it gives a very rich, warm, amber glow.
Hope this helps some. There are a million other ways to do what you asked, this is only one of them that I happen to be familiar with and have used many times with good results.
