how long does primer take to dry on walls
Primer Drying Time. Ideal temperatures for drying time may vary depending on the primer manufacturer, but most recommend applying primer in temperatures that are about 77 degrees Fahrenheit, with a relative humidity of 50 percent. Most latex primers dry to the touch within 30 minutes to 1 hour. But do not paint the wall until the primer dries thoroughly, which can take up to 3 hours. High humidity and cool temperatures prolongs drying times.
