I am (trying to) finish up a humidor I’m working on, which is based on the Wood Whisperer guild plans. I’m attempting a high gloss lacquer finish. This is my first time working with lacquer.
The wood/veneer was sealed with shellac, then pore filled with Timbermate. I used spray can lacquer, a brand from Lowes since I could not find any locally available lacquer for my HVLP gun. I applied 10 coats. I then let the finish cure for about 10 days.
I began the rubbing out process today. I flattened the surface with 320 grit wet/dry sandpaper using soapy water as a lubricant. Following this I used a ROS with Abralon pads at 500, 1000, 2000 grit. It was after this step I noticed a problem. I believe I sanded through the finish. Please see pictures below.
Any thoughts on what to do at this point? I understand lacquer is repairable, should I reapply lacquer just to the affected areas, or to the whole project, repeating several coats again? I can only spray lacquer outside (I don’t have adequate ventilation in my below grade shop) and the weather is getting too cold for a good outcome.
I was thinking about brushing lacquer in the garage. It’s my understanding that brushstrokes or other imperfections can be taken care of in the flattening process before rubbing out. Should I just brush and rebuild a coat on the bad spots? I’m happy with the finish on the good portions. After building finish on the bad spots I would take the whole project through all of the rubbing out steps again.
Lastly, I think some of the pore fill may have been disrupted during the wet sanding. I’m thinking I’ll just pore fill with more lacquer in the affected areas.
Argh, 3 weeks of finishing work down the drain! Thoughts on the best way to repair? Thanks!
