Topic tags/keywords: question finishing sanding shellac

Okay, so I’m working on another cribbage board, and it’s almost done, but I just had a minor finishing disaster—I was using a 4000 grit micromesh disc on my ROS, apparently lingered a bit too long on one place, and the freaking shellac melted into a couple spots of brownish goo, and immediately rehardened. I’m afraid to scrape, in case I dig down to the wood, and I’m still hoping to salvage some of the coats of shellac. Now, in addition to the tiny globs, there are some low spots in the finish, too. Is there an easy fix for this mess? What if I lightly rub it down with some denatured alcohol? Would that cause more problems? What about using a rag to rub in a really thinned coat of more shellac? Or would the best bet be to just settle in with a sanding block and some 400 grit? Any ideas? Thanks, guys!

Yes
You can wipe off evenly your shellac finish with alcohol.
The finish will pull off little bit, but if you do it gently, so you will get the even result.

After you get the even color then you can sand little bit to smooth the surface.
Then you need to redo your shellac application

Sweet, thank you! The alcohol helped level it quite a bit, and I think when it dries again, I’ll be able to sand it smooth easily. I’ll definitely need to add more coats now, but I think I’ve only lost about 2 or 3 coats—I was afraid I’d have to sand to bare wood and start over. I’ll definitely leave the trusty ol’ random orbit sander on the shelf this time, though. Thanks again, Wisno!
