Anyone have suggestions on how to successfully store urethane between jobs?
I have problems with mine gelling when I don’t use it for a few months.

I use Bloxygen. It’s compressed argon gas in a can. Argon is inert and heavier than atmospheric gasses, so it lays down on the surface of the liquid in the can and prevents contact with oxygen. A $12 can treats a quart can 75 to 100 times after opening.

Don’t let anyone tell you to store it upside down. That’s a myth.

I’m sure Bloxygen is the best way to
go about it. You can also transfer
the finish to smaller jars so there’s less
room for air in there.

Thanks, Rich!
That sounds like the perfect solution.

Since it’s a “heavier than oxygen” gas, I presume that when you re-open the can of finish, just a light wafting of air over the opened can would dissipate the layer of Bloxygen. Then when done, just add another new ‘layer’ and seal the can. Am I thinking correctly on this?

Loren, I truly thank you for your idea, but I did that. :(
When I opened the smaller container, that’s when I found a gelled glob of urethane. Tried thinning it with Mineral Spirits – had some success but I know from experience that when you thin anything, the finish and characteristics don’t always remain the same.

It’s inert, trainman, so just use the finish like you would if it was a fresh can. And yeah, use it every time you close the can back up. It includes two of the red tubes that fit in the spray head, so just lay the lid back on the can with the tube poking in, give it a second or two spray, slip the tube out and seal the lid. It doesn’t have to fully displace the air in the can — just enough to cover the surface of the finish.

Getting two tubes is a bonus too. I’m always losing those things :)

This is another solution. Isn’t perfect, but works well for me: http://www.stoplossbags.com/

Close the lid and turn the jar upside down for a moment.

Do you have to say any magical incantations? What purpose could possibly be served by doing that?

Thanks to all! I do appreciate the help.

I searched for a topic/blog on this before starting this one and apparently I never hit the correct phrase because I found nothing. The link “Kazooman” supplied should have shown up, but for some reason, did not.

I just ordered a can of Bloxygen so will soon try it out.

I like the “StopLossBag” idea as well. Might give them a try soon and do my own in shop comparison between the two.

Thanks again to all who responded!

I use Arm-R-Seal & had issues with getting heavy skim in can after using. Short story I was doing a lot of things wrong including working out of the can. Went to local woodworking shop & they suggested Bloxygen but did not have any in stock.

Do not recall how (think it was on LJ but not sure), but found info that compressed air cans for electronics, etc had either the same ingredient or similar & heavier than oxygen & would work same. So bought a can (Ultra Duster) from WalMart & found it worked & a lot cheaper.

Just bought some more (4 10 oz cans of Dust Off) for something like $14 – should last me forever & have other uses too.

Can of Ultra Duster says it contains 1,1-difluorethane )HFC-152a). CAS#75-37-6.

I use a tip that came around in one of the off-line woodworking magazines: a plastic pop bottle. Like the stop-loss bag noted above one simply fills the bottle and then mashes the bottle to a point where only a minimal amount of air is left in the bottle. If you’re not in the part of the country where they drink pop then a plastic soda bottle might serve as an acceptable substitute. :)

The polyurethane ( or whatever is in the jar will seal all gaps and crevices between the jar and the lid) But sure saying something like “Oo ee oo ah ah ting tang walla walla bing bang” does not hurt.

Yeah, but you still have the oxygen in that space. That’s the thing that’s causing the thickening and skin formation. Same thing with the storing upside down I mentioned in my first reply here. Sure, the skin will be on the bottom when you invert it, but the overall damage to the finish will still have occurred.

Now, if you throw in some Love Potion Number 9 — totally different story.

There really is not enough air in a sealed jar to cause any degradation of the content. I used to store all kind of finishes polyurethane including that way for many years and yet to see any degradation in the product.
