Wise Owl 100% Hemp Seed Oil is perfect for restoring old, dry wood. You will be amazed at what Hemp Oil can do! You can also seal Chalk Synthesis Paint with Hemp Oil for an ultra-soft, buttery feel. Avoid use over white Chalk Synthesis Paint; Hemp Oil has a slight amber color that may slightly darken whites. Apply with a brush, let it soak in for about 30 minutes, then wipe away the excess with a lint-free cloth.
