How Long to Wait for Primer to Dry before Painting?

Hey Diksha. Recently, during my house interior painting, I asked my painter how long to wait for primer to dry before painting. He advised letting the primer dry for at least three hours in order to achieve a smooth and even finish. Furthermore, he informed me that it also depends on several factors, such as coating thickness, ventilation, humidity, and so forth.

How Long Should Primer Dry Before Painting?

My painter informed me that latex primers usually dry to the touch in 30 minutes to an hour. However, you should wait to paint until the primer dries completely, which can take up to 3 hours. It completely depends on the temperature and humidity. 

• He further added that if you are using oil based primer, it is best to leave it for 1 to 3 hours. When I asked him why it is required to leave so long, he said by doing so the primer provides a solid foundation to which the paint can adhere.

• He also said that if the primer is not completely dry before painting, the paint will peel, split, or bubble. This can cause a number of problems, including damaging the paint finish and taking more time and work to fix.

I hope you get an idea of how long to wait before painting over primer.
