How to Paint a Garage Door: A Step-by-Step Guide
A garage door takes on more wear and tear than almost any other exterior surface––sun exposure, humidity, dust, kids’ sports equipment, BBQ smoke, daily use, you name it! Because of this, garage door paint fades faster than most homeowners expect. If your door is looking dull, chipped, or uneven, a fresh paint job is one of the fastest ways to boost curb appeal.
This guide walks you through:
Which paint to use for vinyl, wood, or metal garage doors
How weather affects adhesion and why timing matters
How to prep the door to avoid peeling, cracking or bubbling
When to apply a second coat of paint and how long to wait before applications
What to do if you want the job off of your plate completely
What Paint Should You Use on a Garage Door?
Choosing the correct paint is the most important part of the entire project. The wrong paint will peel, crack, bubble, or fair to bond. Sometimes within weeks! The right paint depends on your garage door’s material. Typically, you’ll want a quality latex exterior paint paired with the right primer. You can check the sticker or label on the inside of your garage door to confirm whether it is vinyl, wood, or metal. Here is a quick guide:
Step One: Choose the Right Weather Window
Weather is one of the biggest factors in whether the paint bonds properly. Aim for conditions between 50 and 75 degrees, low humidity, and no direct sunlight. Painting in the rain, or before or after rain, can lead to:
Poor adhesion
Cracking
Bubbling
Trapped moisture under the paint film
If you can, choose a weekend of a 2-3 day window where temperatures are steady.
Step Two: Prep the Garage Door Surface
Prep determines how long your new finish lasts. Most failed paint jobs come from poor prep––not poor paint. We recommend doing the following:
Remove rust, peeling paint, and grime using a wire brush
Sand the surface with a fine-grit pad to create a smooth base
Clean thoroughly using all-purpose cleaner and large sponge
Rinse with a hose and let the door dry completely
Power washing works too, but is optional. If you see missed spots, repeat cleaning until the surface feels smooth, clean, and residue-free.
Step Three: Tape and Protect Your Surroundings
Use painter’s tape to cover:
Handles
Locks
Weatherstripping
Trim
Lay drop cloths to project the driveway and garage floor. Clean lines and a tidy workspace make the final result look professionally done.
Pro Tip: Turn off the garage door opener and lift the door manually as you work. Adjusting the door height saves your back and gives you better control.
Step Four: Prime the Garage Door
Start with the inset panels, then roll the larger flat sections. Wipe away any excess primer immediately to prevent ridges or drips. Remember to let the primer dry for 24 hours for best adhesion.
Step Five: Paint the Garage Door
Begin with the inset panels again, then work outward:
Paint the panel recesses with a brush
Paint the panel frames
Paint the outer edges
Roll the flat areas in smooth, even passes
Work in small sections to maintain a wet edge and reduce lap marks.
Step Six: Apply a Second Coat
Most garage doors need two coats for full coverage and color consistency. Allow the first coat to dry for at least 24 hours, then apply the second coat using the same method. Once fully dry, remove the painter’s tape carefully for crisp lines.
