Today, we’ll walk you through everything you need to know to paint your garage door like a pro. From gathering the right supplies to expert tips that make the job easier, you’ll have your garage door looking brand new in no time!

Supplies You’ll Need to Paint a Garage Door:

• Exterior paint (latex or oil-based, depending on your door material)
• Primer (if needed)
• Painter’s tape
• Drop cloths or plastic sheeting
• Paint rollers (smooth or medium nap)
• Paintbrushes (for edges and details)
• Sandpaper (fine grit)
• Power washer or garden hose
• Mild detergent and water
• Ladder
• Paint tray
• Stir sticks

How to Paint a Garage Door: 

• Start by cleaning the garage door thoroughly. Use a power washer or garden hose with mild detergent to remove dirt, grime, and any peeling paint. Let it dry completely.
• If the door has rough spots, rust, or peeling paint, sand the surface lightly with fine-grit sandpaper to smooth it out. Wipe away any dust with a damp cloth.
• Use painter’s tape to mask off any areas you don’t want painted, like handles, windows, or trim. Lay drop cloths around the base of the door to protect the ground.
• If your garage door has bare metal or wood, apply a coat of primer. This will help the paint adhere better and ensure long-lasting results. Allow the primer to dry according to the manufacturer’s instructions.
• Stir your paint thoroughly. Use a roller to apply the paint to the larger sections of the garage door, starting from the top and working your way down. Use a paintbrush to cut in around edges and corners. Apply in thin, even coats.
• Allow the first coat to dry completely before deciding if a second coat is needed. Most garage doors will need two coats for full coverage.
• Once the first coat is dry, apply a second coat of paint for a smooth, durable finish.
• Carefully remove the painter’s tape while the paint is still slightly wet to avoid peeling. Clean up your brushes, rollers, and trays.
• Make sure the garage door stays open for a few hours so the paint can dry without sticking to the weatherstripping or frame.

Tips and Tricks

• Choose the Right Paint. Use exterior paint that’s designed for the material of your garage door, whether it’s metal, wood, or vinyl. This ensures durability and protection from the elements.
• Paint in Good Weather. Plan to paint when the weather is mild, with temperatures between 50-75°F and low humidity. Avoid painting in direct sunlight to prevent the paint from drying too quickly.
• Use Thin Coats. Applying thin coats of paint will help you achieve a smooth finish without drips or streaks. It may take longer but gives the best results.
• Keep the Door Moving. Open and close the door occasionally while the paint dries to prevent it from sticking to the frame.
• Inspect for Imperfections. After the first coat, look for any spots that need extra sanding or touch-ups before applying the second coat.

What type of paint is best for garage doors?

The best type of paint for garage doors depends on the material of the door. For metal garage doors, a high-quality exterior latex or oil-based paint is ideal as it provides durability and protection against the elements. For wooden garage doors, exterior latex paint works well because it resists cracking and peeling while expanding and contracting with the wood. Vinyl or fiberglass garage doors should also be painted with a latex paint specifically designed for exterior surfaces. Be sure to choose a paint with UV protection to prevent fading and ensure long-lasting results.

How many coats of paint do I need for a garage door?

Typically, you will need two coats of paint for a garage door to achieve a smooth, even finish. The first coat provides the base, and the second ensures full coverage and durability. If you’re painting over a dark color with a lighter one, two coats are usually necessary to prevent any old color from showing through. However, if you’re using a high-quality paint that offers excellent coverage, one coat might be sufficient for minor touch-ups. Always allow the first coat to dry completely before applying the second for the best results.
