A professional painter can take 5 to 6 hours to paint the walls and the ceiling of a standard 12 feet by 12 feet room assuming that the condition of the walls is fine, and that it needs an application of two coats of flat paint. Two to 3 more hours may be needed for painting the door, baseboards and windows.
