    Obvious as it sounds, you should use exterior paint on exterior doors. Exterior paint has antimicrobials to prevent the growth of mildew, mold, and algae. Plus, it holds up better against UV rays. That's most important when painting front doors.

    No. In fact, it's better to paint while the door is hanging.

    You'll have to remove the door and sand, prime, and repaint it.
  • Question
    I am painting the exterior and interior faces of the door different colors. What color should I paint the sides of the door?
    Community Answer
    When you paint the inside and outside of a door different colors, you typically paint the sides based on what shows from the side of the door you're on. When you're outside, the side where the hinges are will show when the door is open. Therefore, paint the hinge edge the same color as the outside. When you're inside, the lock side of the door shows, so you'll want to paint the latch side of the door the same color as the interior.
  • Question
    How do I know if a door I want to repaint was painted with an oil or water based paint?
    Community Answer
    Soak a piece of cloth, or a cotton ball, with rubbing alcohol and wipe it across the painted surface. If some of the paint rubs off, then you know that it's latex, a water based paint.
  • Question
    What is the minimum temperature at which I can use oil based paint?
    Community Answer
    The 60° F guideline is ideal. The minimum application temperature on the label should be followed carefully. This typically is 50° F for latex paints.
  • Question
    How long will it take to prepare doors?
    Community Answer
    Preparation time will depend on how much you have to do. For instance, if you have holes to fill, giving the caulk time to dry will add a few hours to the job. Otherwise, cleaning, sanding, washing, and drying the door will likely take a couple hours. The longest part will be waiting for the door to dry after you wash off the dust and excess cleaner.
  • Question
    How do you determine whether paint is oil-based or water-based?
    Community Answer
    It should say on the tin, and it's easy to tell just by looking. If you still can't figure it out, mix a little water with a little bit of the paint. If the paint and water won't mix, then the paint is oil-based.
  • Question
    Should I sand a new door?
    Community Answer
    If the door has already been sanded, then you can proceed to priming and painting. But if the door hasn't been sanded, or you don't know if it has, you're best to sand beforehand. This will ensure the best results, and it won't hurt the door to be sanded twice if it's already been done.
  • Question
    My wooden door was previously varnished. What preparation do I need to do before I paint it?
    Community Answer
    Sand it down and use a primer - gray for normal colors, or white if you're going to go with a light color such as yellow. Then paint the top coat.
