I recently posted a question about using shellac as a finish for our interior pine doors. We just finished all 8 doors, so I thought I would share my experiences in hope that it will help someone in the future.
Our doors were 6 panel pine doors purchased at Lowes. While they "look" like solid wood, they appear to be a laminated product of some sort. One of ours started delaminating and we had to return it. The jambs appear to be finger jointed pine with a pine veneer. It all looks fine once it's installed though.
Anyway, after experimenting with a few different finishes, I settled on Zinssers premixed Amber Shellac. It say's it's a three pound cut straight from the can, but that really means nothing to me.
I put two coats straight from the can on the first door. It looked OK, but it was rather glossy and kind of splotchy looking. I tried rubbing down the finish afterwards with 400 grit sandpaper and mineral spirits, which helped, but still wasn't the look I was after.
After a bit more experimenting, I came up with a method that produced nice results:
- Sand the bare door with a 150 grit foam sanding block.
- Apply a "thin" coat of Amber Shellac straight from the can. Be very careful not to leave brush marks, drips, or runs.
- Wait a couple of hours, then sand the door with 180 grit foam sanding block.
- Prepare a can of Amber shellac that is roughly half shellac and half denatured alcohol.
- Apply the "thinned" coat of Amber Shellac to the door.
The result is a finish that is easy to apply, has a nice color, but is not too glossy.
On a side note, I actually found it easiest to finish the door and jambs in place. We removed the first door and tried to finish it while it was laying down, but it was actually more awkward to work with, and the shellac puddled easily in all the little crevices.
