Customer didn't want mineral oil so we decided to spray a urethane on it. They are not using it as a cutting board.
My question is the top is maple and the urethane is a general finishes water base. So I put a coat of shellac sealer first then sanded lightly with a 400 grit. It's smooth but not like I had it before.
If I was to sand it again with a 220 to bring it smooth again would I be ok to spray the water base or would the grain come back up after sanding the shellac sealer. Wondering if it would be soaked in enough that I wouldn't have to worry about that now?
