Preserving Unused Finish?


Question (*1):

I have a homemade finish of 1 part BLO, 1 part TO, 2 parts varnish,
and 2 parts pure terps.

The unused portion of the last batch I made, (and stored in a closed
mason jar), turned all icky-gooey(*2) on the top third or so, making
it, (I assume), unusable.

Can I preserve what's left of my current batch by covering it with a
film of plastic wrap like I do with unused paint or is this a really
baaad idea? If so, any suggestions? (*3)

*1) I'll ask the dumb questions, so you don't have to.
*2) "Icky-Gooey" is not, to the best of my knowledge, a real
wooddorking term. You'll have to use your imagination. :)
*3) Besides making up less of the recipe like I should have? ;>

I made some up a while ago except it was 1:1:1. I purge opened cans
with either nitrogen or argon and have no problem. If you don't have
these gases available Woodcraft has a product for this purpose called
Bloxygen that I would guess is nitrogen. The objective is to purge all
oxygen and water vapor from the can before sealing it.

woodfinishingsupplies.com also has Bloxygen, as well as more of your
other ingredients to make yourself a new batch..

Yes. It's started to polymerize due to exposure to oxygen.

If it was completely protected from air, you could try this, but if it's
iff I would toss it and make up a fresh batch.


There's a few things you can do to keep this from happening again. The
best one is to get a can of Bloygen, which is a mixture of inert gasses
that is heavier than air. You squirt it into the jar, and the gas settles
on top, preventing any oxygen contact. You can get it at woodworking
stores, as well as liquor stores (it's sold to protect wine as well).

Bloxygen. Sounds perfect.
