Intro
Painting doors is usually the last task of an interior painting project. When you get to this step, you can either paint the doors in the frame or take them down and paint them. Removing them takes a little more time but is easier in the long run, and the result will prove more satisfactory because you're working on an uninterrupted surface. And if you support the doors on sawhorses or some other horizontal structure, the finish will level itself out more smoothly.
No matter how you plan to paint the door, remove the knobs, lockset, striker plate, and any other hardware. That way you won't have to paint around them, which can leave swirls in the finish.
To remove the door, pull the hinge pins as shown. Then mask the hinge plates with two coats of rubber cement and set the door on a horizontal surface. If you support the door with screws driven into the top and bottom as shown below, you can flip the door (with a helper) and paint the other side before the first one dries. Using the screws as supports keeps the sawhorses from marring the wet paint.
