Full Answer

The drying time for a primer varies depending on the manufacturer, room temperature, interior or exterior application and the type of primer. Check the manufacturer's product specifications, which are typically printed on the label, for exact drying times.

The use of primer before painting improves the paint's ability to adhere to the surface. It results in an even paint finish that remains attractive and durable.
