How to Paint Over Shellac

Paint can be applied over shellac.

Shellac is a finish commonly used on raw wood surfaces to prime or seal. As a primer, shellac serves a base coat before a surface is ready to be painted. Shellac is normally applied to a surface that has previously been sanded and is applied using a roller. Shellac dries quickly, usually within two to three hours, but it is best to let the shellac primer dry for 24 hours or overnight before you begin painting over it.
