I have a minwax poly stain mix and used it well over a year ago then closed it and put in away. I went to open it up and use it a week ago and it was solid. I need to know if I can fix that or if it is ruined. I have searched online but not finding anything, either most know how to keep it from happening or it is ruined I don’t know. My daughter love her to death but she pulled the label off a while back so if there is info on the label please let me know. It was not in a hot place and was closed tight so any help is appreciated.

There is no fixing it. I’d also suggest keeping it away from your daughter.

I’ve had poly last a long time, much longer than a year, so id say it wasn’t air tight for some reason. It will also get hard quicker if there is only a little left in the can.

I second what Don said. If it’s solid, it’s basically cured, and you can’t reverse that. Maybe a small piece of saran/cling wrap under the lid when you put it away for long term storage would work better.

Junk. I started exhaling into the can just as I replaced the lid on all finishes. Remember that most of our air is a high nitrogen mix. Inert gas (nitrogen) helps prevent curing. Not a total prob solver, but sure helps.
Film wrap under the lid won’t keep the air from the finish. Placing the film ON the surface of the finish will help.
Think about what Bloxigen does.
I must add that I sure got some funny looks from my bride when she first saw me blowing into a paint can.

A good tip I learned recently – if you are a welder, hit the can with some argon before you seal it up. If you are not a welder or do not have argon, fill the can with glass marbles to remove as much “space” as you can.

Aren’t glass marbles worth more than the poly these days :-)

They cost about as much as 1 quart of Arm-R-Seal, however they cost a lot less than the four 3/4 full cans of solid material I used to call Arm-r-Seal :)

If the volume of projects I finished was great enough where I could go through finish quickly, it wouldn’t be an issue. A quart of finish will last me a LONG time.

Glass marbles can also be recycled. They last until….well you lose your marbles.

Have your say...
