Topic tags/keywords: lacquer shellac paint cornhole

Hello! I’m making some cornhole boards and struggling with the finish. I did a few coats of gloss lacquer on the whole thing and then taped it off after it dried and did the colors in spray paint. After peeling up the tape I noticed a ridge from the height difference and I tried to smooth it all out with a top coat of lacquer. I know now, big mistake. The paint wrinkled up and I had to sand it off and start over. I’m back to having the ridge instead of a nice smooth top. I would like to top coat it with something to make it glossy and durable but I’m not super interested in choosing wrong and starting over again. I was thinking about shellac (zinsser) over the whole thing and then lacquer or General Finishes Arm R Seal.

Does anyone have any idea if the shellac might dissolve the spray paint at all? My bigger concern is that the lacquer might dissolve the shellac and eat up the paint.

I realize there was likely a better way to go about this from the start and I’m open to hearing about that too.

Thanks!!

I will tell you the way I did it. It worked out nicely. After sanding the 1/2 inch birch plywood surface to 220 grit, I masked and painted the colored surfaces with rattle can spray paint. It took 3 coats to get the finish I wanted. Then I sprayed the whole top with polyurethane varnish. This took a total or 3 coats. I sanded between the second and third coats with 320 grit to remove the dust nubs. After the third coat, I “sanded” the top surface with a section of brown paper bag. This produced a consistent smooth surface with very small ridges where the color was applied. That is it.

I suspect where you went wrong is choosing lacquer instead of polyurethane as the clear coat. Lacquer thinner is a very powerful solvent and dissolved the color paint as it was applied. Lacquer is also less durable than polyurethane and I would not have chosen it for this application for that reason alone.
