How many hours should the Kilz primer dry before applying an Epoxy paint topcoat?

Kilz primer typically requires about 1 hour of drying time before you can apply an epoxy paint topcoat, but it's best to wait at least 4 hours for optimal adhesion. Ensure the primer is fully dry to the touch and follow the manufacturer's instructions for the specific product you're using. Additionally, environmental conditions like humidity and temperature can affect drying times, so allow for extra time if needed. Always check the label for any specific recommendations.
