Has anyone used wood finished with Minwax polyurethane? My husband came home from work with a project for me and they pieces are heavily coated in the product. If that is safe to engrave, what the heck setting do I use to get through the polyurethane to the hardwood? Major concerns here! Help!
Welcome back! It’s been a while.
This topic has been covered a few times, though it is a bit tough to figure out what to search for.
Your going to have to sneak up on your settings by experimenting.
Thanks! What do you think is the time necessary for curing mentioned in that article? I believe I have what they used -polyshades - and I can try to finish a piece of scrap to run a tests on. I don’t want to screw up a project for this business!
It should say on the can how long. Probably 24 hours?
That’s the only way to be sure. You need to test on pretty much any material before committing to a large job.
FWIW, most materials from GF store are pre-finished, but of course they have used materials they know won’t harm the machine.
Good or not, I usually coat all my wood with Polyurethane prior to lasering. Saves time in the long run.
