Finish Help! - Spar urethanes

klowwn

Help! In the middle of a project I was using a spray can of Rustoleum Spar Urethane Semi Gloss. After spraying the project with one coat and just starting on the second coat the spray can just stopped spraying. By weight I can tell the spray can is almost half full, but the propellant must have expired.

Locally Menards, Lowes, Home Depot, and Ace Hardware all carry Rustoleum products but none carry the Spray spar urethane.

Can I finish the project spraying with Minwax Helmsman Spar urethane without sanding off the Rustoleum? Or do I need to start over from bare wood?

Thanks

soak the nozzle in lacquer thinner

take it off the can, soak it. It may just be plugged with a piece of varnish. After that, no idea what is compatible with it. Sorry.

Thanks for the idea Dick. But I should have clarified - it stopped mid spray. It was spraying and then just stopped. I did however check the nozzle and clean it with a fine wire and thinner but no success.

In some cases, it's that the can is out of propellant.

If you search Google for "recharge aerosol can air" you will find several videos that show how to use a compressor to add air as a propellant.

It might work for you, if that's the cause of the problem. If the intake tube is clogged at the bottom of the tube, then recharging might clear the blockage.
