How Long Does Primer Take to Dry?

The time it takes for primer to dry varies with different manufacturers, temperatures and humidity levels. Types of primers include oil based, latex, enamel and all purpose. Some are a combination of paint and primer. Latex primers typically take between 30 minutes to one hour to dry.

The ideal temperature recommended for applying primer is about 77 degrees Fahrenheit with a humidity of 50 percent. Primer drying time can be prolonged in high humidity and cool temperatures. In such conditions, primer may take up to three hours to dry, which can delay paint application. Well-dried primer ensures a long-lasting paint finish.
