The instructions for Zinsser brand clear shellac says: "not recommended as a sealer under polyuerthane finishes"
I have Minwax Helmsman Spar Urethane. Can a urethane finish be used over shellac?
What is the difference between polyurethane and urethane. The Minwax Spar Urethane can says not for use on floors. For floors use polyuetrhane.
