Materials You’ll Need

Before you get started, here are the materials you’ll need to complete the project:

  • Sandpaper
  • Painters tape
  • Paint primer
  • Paint roller and tray
  • Exterior-grade black paint
  • Paintbrushes
  • Drop cloth

Step-by-Step Guide

Step 1: Prepare the Surface

The first step to painting your garage door black is to prepare the surface. Start by cleaning the door with a mild detergent and water to remove any dirt, dust, or debris. Next, use sandpaper to rough up the surface of the door. This will help the primer and paint adhere better to the door’s surface. Be sure to remove any peeling or loose paint, and fill in any cracks or holes with a suitable filler.

Step 2: Apply Painter’s Tape

To ensure that you achieve a clean and professional-looking finish, apply painter’s tape to the edges of the black garage door with windows, trim, and any other areas that you don’t want to paint. This will help to prevent paint from getting on areas that you don’t want to paint.

Step 3: Apply Primer

Before you start painting your garage door black, it’s essential to apply a coat of paint primer. The primer will help the paint adhere better to the door’s surface, and it will also prevent the door’s original color from showing through the black paint. Use a paint roller to apply the primer evenly to the door’s surface.

Step 4: Paint the Door

Once the primer has dried, it’s time to paint the garage door black. Use a paint roller to apply the paint in long, even strokes, starting at the top of the door and working your way down. Be sure to apply the paint thinly, and avoid drips or runs. Use a paintbrush to paint any areas that the roller can’t reach.

Step 5: Allow the Paint to Dry

After you’ve finished painting, allow the paint to dry for at least 24 hours before using the garage door. This will allow the paint to cure properly and ensure that the finish is durable and long-lasting.
