Best Ways to Seal Osmo Polyx Containers?

Asked by User1234!
I'm a big fan of Osmo products like Polyx, but I've had some issues with the containers, especially the lids. They seem pretty flimsy and don't seal well after I've opened and closed them a few times. I'm looking for tips on how to better seal my Osmo cans. Do you guys transfer the product to other containers, like StopLoss bags or something similar? Any advice on how to store leftover Polyx between projects would be greatly appreciated!

I usually pour my leftover Polyx into mason jars and vacuum seal them for storage. It keeps everything fresh until I need to use it again!

For all my paints and finishes, I use Finish Preserve from Lee Valley. It's a gas that displaces oxygen in the container, which helps a lot. Just a quick 2-3 second burst does the trick. I haven't had any issues with my Tung Oil or rubber cement hardening since I started using it!

DIYEnthusiast88: Does the gas stay in there even if the lid isn’t completely sealed?

A common method is to decant them into glass jars with tight-fitting lids. It's a bit of a hassle, but it works if you're serious about keeping it fresh!
