How To Paint A Door

Getting the edge, Sand a door’s edges before repainting the door. Too much paint may cause the door to stick in the frame.
Mess-free scraping, When removing old paint or stain from a door, keep the messy remnants from sticking to the scraper by periodically applying nonstick cooking spray to the blade.
Before painting, straighten out minor warping in a door by adding an extra hinge. Or remove the door, place it on sawhorses, and lay a heavy weight on the bowed section to correct the curvature.
For paint-free hardware, cover each hinge leaf with a piece of packaging or masking tape, trim the excess, and then paint without spatters or runs.
Bottom up. To paint the bottom edge of a door without removing it, apply a generous layer of paint to a scrap of carpeting wide enough to hold comfortably with both hands. Then slide the carpet under the door and rub it back and forth to coat the bottom edge.
Colour correct, Paint the door edge the colour of the room into which it opens.
