How long does it take for a Behlen Top Coat spray can lacquer finish to completely cure? Can implies 24 hours.
I just finished the final last of 15 coats of spray can (Behlen Top Coat) nitrocellulose lacquer on the never-ending Christmas box project. All I need to do is let the finish cure. How long should I wait for the lacquer to cure to hardness before I pack it up and ship it? The first 3 coats went on about 3 weeks ago. Also, if I were to rub it out (which I dare not even THINK of doing one more thing to this box) how long would I need to wait?
Several days after the previous "last" coat, I inadvertently got a little shellac on the surface. No problem I thought, lacquer is alcohol proof, so I will wipe the shellac off with a little DN alcohol on a soft cloth. Really really bad move. It removed the lacquer as well! What was up with that? The more I rubbed, the worse it got- it took off a couple of small spots almost down to bare wood. I would not have expected that. As it turns out, just a thorough light sanding/ feathering with 320 and one "last" coat fixed it- it blended right in.
