How to Paint a Metal Door

Maybe you simply want to change the color of a metal door, or maybe the existing paint is peeling off. Whatever the case, you can paint a metal door and make it look like new again. Although the task is easy, it can also be time-consuming. The worse shape your door is in, the more preparation time you'll need for the project. Once you're finished, however, you'll be proud of your work and realize how much your prep time paid off.

Step 1

Remove all hardware, including locks, knobs, kickplates, and knockers with a screwdriver. If possible, also remove weatherstripping. Place the hardware, along with screws, together in a container to ensure they don't get lost.

Step 2

Remove any small areas of loose paint with a paint scraper. If the majority of paint is in bad shape, use paint remover to strip the metal door. Follow the manufacturer's instructions for best results. Apply the remover with a brush and wipe off the dissolved paint after the designated amount of time noted on the instructions.

Step 3

Use denatured alcohol and a cloth to clean the metal door to make sure it is free of oil, grease, and other contaminants. This step ensures the paint will adhere properly to the surface.

Step 4

Cover glass or screen sections in the metal door with newspaper and painter's tape. Block off any weatherstripping that's still attached before you begin to paint.

Step 5

Apply a metal primer to the door with a brush, if you previously stripped the paint—or if there are bare spots exposing the metal. If you use a different type of paint than the existing finish, you'll also need to apply primer to ensure the new paint sticks properly. Always follow the directions on the container, and allow the primer to dry before you proceed.

Step 6

Paint the metal door by using a short nap roller and a paint pan. Not only will using a roller make your job quicker, but it also won't leave brush marks. If there are indentations in the metal, use a small 4-inch roller so you can reach them. After the first coat of pain has dried, apply a second coat, if necessary.
