When applying single stage urethane, you should wait 15-30 minutes between coats. This gives the paint a chance to dry and settle before adding more layers to ensure an even finish. Additionally, it is important to let the paint cure for 48 hours after the final coat before exposing it to dust or contact with water or solvents. During this time, it’s best to keep your finished project in a temperature controlled environment as extreme temperatures can cause issues with drying times and bonding of the paint layers together. Following these guidelines will help you achieve an even finish on your next single stage urethane project!
