How to Make a Mess-Free Varnish Filter out of Cheesecloth
If you need to filter an old can of varnish, polyurethane, or other clear finish for a small touch up job, you could pour the whole thing through a filter and make a mess… But, there’s a better way.
This is a tip from Don Mathis of Macomb, IL. Instead of pouring the varnish through a filter, Don puts a filter in the can. He takes multiple layers of cheesecloth and lowers them into the can of varnish. The varnish comes up through the cheesecloth and filters itself. Now he’s got filtered varnish, ready for any small finishing project.
