While The Can Is Open

Posted by Mac on Sep 9, 2004

Earlier this summer we were on the subject of varnish, and someone came up with the trick of keeping varnish and paint from skinning over in the can - especially once a goodly amount has been used and there is a lot of air in the container. This means oxygen - the agent that makes varnish and paint dry or cure.

The trick was to fill the space in the can with heavier-than-air butane or propane from an unlit torch to displace the air. As these gases contain little or no oxygen....

Tried it - works great!
