Prior to using the Magnetic Primer be sure to stir thoroughly to ensure any settled pigment is re-dispersed, also stir thoroughly during application. Three coats of primer are recommended, waiting 30 minutes between coats. Chalkboard Paint can be applied 4 hours after the last coat of Magnetic Primer, do not apply more that two coats of Chalkboard.
