Transformative Tips and Tricks for Painting Your Garage Door


Your garage door is often the most visible part of your home’s exterior. Painting it can completely transform the look of your house and increase curb appeal. However, painting a garage door requires proper preparation and technique to get great results. This comprehensive guide covers everything you need to know, from choosing the right paint and supplies to prepping, painting, and caring for your freshly decorated garage door.

Key Takeaways

  • Properly prepare the surface by cleaning, sanding, and spot priming
  • Use exterior-grade latex paint and primer formulated for metal or wood
  • Roll paint on panel-by-panel working top to bottom
  • Allow proper drying time between coats
  • Seal the paint with a clear coat for added protection
  • Inspect weatherstripping and hardware while door is accessible

How to Choose the Right Paint

When selecting paint for your garage door, opt for a high-quality exterior-grade latex paint. Oil-based paints are not recommended for garage doors as they can crack over time. The latex formulation allows for expansion and contraction as the door moves and adjusts to weather. For bare wood doors, use an exterior latex primer followed by two coats of latex paint. For metal doors, use a dedicated metal primer before painting.

Supplies You’ll Need

Here’s a checklist of must-have supplies:

  • Exterior primer (for metal or wood)
  • Exterior latex paint
  • Paint roller frame and covers
  • Angled paint brush
  • Painter’s tape
  • Drop cloths
  • Paint tray
  • Sandpaper
  • Rags
  • Mineral spirits
  • Eye and skin protection

Prep Work is Key

Just as with any paint job, proper prep work ensures successful, long-lasting results. Follow these critical steps:

  1. Clean the Door: Use a mild detergent and rinse thoroughly with a hose. Let dry completely.
  2. Lightly Sand: Lightly sand to roughen and degloss the surface. Wipe clean after sanding.
  3. Spot Prime: Prime any bare wood or metal including scratches and dents with appropriate primer.
  4. Tape Off Areas: Use painter’s tape to mask off trim, handles, and glass panels.

Painting Technique

When you’re prepped and ready, follow this painting method:

  1. Start at the Top: Begin at the top panel and work downward section-by-section.
  2. Cut-In With Brush: Use an angled brush to neatly “cut-in” around edges and corners.
  3. Roll Central Areas: Quickly roll the larger central panel areas after brushing perimeter.
  4. Inspect Between Coats: Check for drips or thin coverage after the first coat dries. Touch up if needed.
  5. Apply Second Coat: Use the same painting method to apply a second finish coat for full color saturation and protection.
  6. Remove Tape: Carefully remove all masking tape immediately after painting before cure.

Extra Protection: Clear Top Coat

For extended protection from elements, apply 1-2 coats of a clear water-based urethane top coat after paint has fully cured 1-2 weeks. This seals and protects the finish.

Post Painting Care

Handle freshly painted doors gently until completely cured. Avoid slamming or repeat open/close cycles. Wash only with mild soap and water using a soft cloth or sponge. Avoid abrasive cleaners. Touch up scrapes or scratches promptly with additional paint to prevent rust or exterior damage.

Time to Inspect Weatherstripping

While your garage door is more conveniently accessible during the painting process, take some time to inspect and replace any cracked or deficient weatherstripping around the perimeter of the door. This will prevent exterior elements, dust and bugs from infiltrating the garage space. Check door hinges and rolling hardware as well making any minor repairs for smooth operation.
