How to Paint a Garage Door

A person prepares to paint a garage door in a few simple steps from prep to priming to painting.

Painting your garage door can update your home with a standout colour that complements your home’s exterior. But before you start painting, consider what goes into giving your garage a brand-new look.

Several elements go into painting a garage door. You should be mindful of hinges and glass windows before starting. You also need to consider the condition of your surfaces. Garage doors can be made from many materials, including metal and wood. Some metal can corrode and rust, while wood might become weathered or require stain.

With the right tools, paint, and prep work, you can turn your average garage door into something that boosts your home’s overall beauty.

Step 1: Select the Right Paintbrushes & Paint

Before you start painting, be sure to select the right paint and tools for the job.

First, pick the right paint or stain. If you are painting a wood or metal garage door, consider an exterior acrylic paint such as Aura® Exterior or Regal® Select Exterior High Build. If you want an exterior stain for your wooden garage door, consider Woodluxe® Exterior Stains.

Use synthetic-bristle paintbrushes for acrylic paint: a 7.6 cm (3-inch) flat sash brush for flat surfaces, and a 5.1-6.3 cm (2- or 2.5-inch) angled sash brush to cut in around edges and windowpanes.

Rollers always work well for large, flat surfaces.

Check the Weather

Use the Benjamin Moore guide for optimal painting conditions. And be sure to avoid rain as well as direct sunlight, which can cause the paint to dry too fast.

Step 2: Prep Your Garage Door for Painting

Before applying any primer or paint, make sure your garage door surface is free of loose, chipping paint and properly dulled from any previous glossy finish.

Disconnect the garage door opener so you can manually move the door up and down as you work—and to keep the door from accidentally moving when you don’t want it to.

Next, use a sponge to scrub the door with an all-purpose cleaner. If needed, pressure wash carefully to remove loose or peeling paint. For stains from mildew, wash with a combination of 65 ml (¼ cup) trisodium phosphate (or TSP, a popular cleaning agent), 65 ml (¼ cup) bleach, and 3.79 L of warm water. Be sure to rinse thoroughly after using TSP and bleach.

Spread a drop cloth under the door to protect the garage floor and driveway.

Sand off any rough edges of paint that didn’t wash off. Use 80- to 220-grit sandpaper, depending on the severity of the edges. Sand until smooth. Be sure not to scratch your garage door’s glass windowpanes.

For metal doors, first loosen any rust with a wire brush, then spot prime those areas with a rust-inhibitive primer like HP Acrylic Metal Primer.

Consult with your locally owned Benjamin Moore store or other professional if there is any significant damage.

Once all that is completed, prepare your space for painting. Tape off windowpanes, trim, and hardware, and clean off debris.

Step 3: Apply the Primer and Garage Door Paint

Once your garage door is prepped, it’s time to apply a primer.

Use a high-quality acrylic exterior primer like Insl-X® Stix® or Fresh Start® High-Hiding All-Purpose Primer.

When applying primer or paint to your garage door, start with the top panel and work your way down. Use a brush to cut in around the trim and edges of the door and fill in any recesses in the panels. Afterward, coat the flat surfaces.

Follow the recommended dry times between coats of primer and paint.

Most projects require one coat of primer and two coats of paint for the best results. If your garage door is already painted and in sound condition—and the colour change is not drastic—a primer may not be necessary.

Step 4: Clean Up

Acrylic paint requires only soap and water cleanup. Be sure to wash your brush before it begins to dry by rinsing it in warm, soapy water. Remove excess water, taking care to keep the bristles in their original shape.

Hang your brush to let it dry. If you saved the brush’s cardboard sleeve, rewrap the dry brush for safe keeping.

Don’t forget to reconnect your garage door opener.

Helpful Tip

If paint drips dry over the seams of individual panels, use a utility knife to carefully cut it away. Use a small piece of sandpaper to clean up rough edges.
