The dry time to overcoat for TotalBoat Topside Primer depends on environmental conditions during the curing process.

• 90 °F: 1 hour
• 70 °F: 2 hours
• 50 °F: 4 hours

Other factors, such as humidity and coating thickness, also affect dry time. It is generally recommended to apply the primer in very thin coats, no thicker than 4 sheets of paper, wait a day, and sand between coats. If the sandpaper clogs during sanding, additional cure time may be needed before recoating.
