GOOD DAY, I am going to grain fill with shellac and was wondering if there is a shelf life for it. Mine is just over a year old. I have Zinsser Seal Coat:
Thanks for the help!

If no one will ever see it, all the more reason to make it right
Has the can ever been opened?
If no - I would expect OK. If not, hard to say.
Ether way - you would be wise to do some tests to see that it cures properly.
If this is a recurring issue, you can always buy flakes, and mix only what you need. The flakes last forever, as far as I can tell, if you keep them in the fridge or the freezer.
When I started woodworking, I didn't know squat. I have progressed in 30 years - now I do know squat.
Shelf life on Seal Coat is 3 years. See the bottom of page 3.

Shellac "Born On" Date
I sent Zinsser/Rust-Oleum an e-mail asking about their shellac. This is their response...
The lot number that you have was manufactured May 17th, 2010.
S05179 reads as follows, S-Somerset NJ.
The first digit after the letter is the year of manufacture 0-2010.
The second digit is the month 5-May. (O-October, N-November, D-December).
The next 2 digits are the day of the month 17-17th day.
The final digit is for our records, the batch was made on the 9th run of the day.
Shellac has a 3 year shelf life.
Thanks guys for all the information. I think I will do a test to check how it cures just to be safe. Again, thank you so much !!

I've never had a can of SealCoat go bad before I used it all, once over two years. I've had two leakers though, one after only a few months, and have learned to set it in a plastic pail to prevent a mess when it next occurs. I still prefer it over buying flakes.

Thanks Glenn. I never thought to ask Zinsser for a refund. Next time.

I have had opened dry flakes kept in my house, not in a refrigerator, still good after several years in Southern California.
I would TESt on scraps before you plunge in..Let it dry to see reults.

I don't know about the canned stuff, but flakes & everclear should last about 5-6 months if you keep it out of the sun.
I just re-opened a can of Sealcoat and tested it prior to use on a smal piece. It had gone bad (the can leaked after opening as well). Test, then use.
