After years of painting garage doors across Hillsboro, I’ve learned that a proper paint job can make a door look brand new for a fraction of replacement cost. The key is preparation and using the right materials for your door’s specific surface.
Most homeowners skip critical steps that lead to peeling paint within months. I’m going to walk you through the exact process we use at ETS Garage Door Repair to achieve long-lasting, professional results.

What Type of Paint Should You Use on a Garage Door?
Use exterior acrylic latex paint for steel and aluminum doors, and exterior acrylic or oil-based paint for wood doors. The paint type matters more than the brand, especially in Oregon’s wet climate where moisture resistance is essential.
For steel doors, I always recommend a paint with rust inhibitors. Our Hillsboro weather can be tough on metal surfaces, and that extra protection pays off over time.
Preparing Your Garage Door Surface
Clean the entire door with a degreaser and water solution, then rinse thoroughly. Any dirt, oil, or mildew left on the surface will prevent proper paint adhesion.
Sand the door lightly with 150-grit sandpaper to create texture for the new paint. This step is especially important if you’re painting over glossy factory finish or old paint.
Fill any dents or damage with auto body filler for metal doors or wood filler for wooden doors. Let it cure completely, then sand smooth before priming.
The Priming Process
Apply a quality exterior primer designed for your door material. For bare metal, use a rust-inhibiting primer. For wood, use an oil-based or shellac primer to seal the grain.
Don’t skip primer even if you’re painting over existing paint. It creates better adhesion and helps your topcoat last years longer in our Pacific Northwest conditions.
Painting Technique That Prevents Drips and Runs
Remove all hardware you can, including handles and decorative elements. Tape off windows, weatherstripping, and anything you don’t want painted.
Work from top to bottom in sections, painting one or two panels at a time. Use a high-quality brush for edges and recessed areas, then a foam roller for flat surfaces.
Apply thin, even coats rather than one thick coat. Two thin coats always look better and last longer than one heavy application that sags and drips. If you’re considering a completely new look, check out our Door Designer to explore your options.
Can You Paint a Garage Door in Cold or Rainy Weather?
Paint when temperatures are between 50 and 85 degrees with low humidity. In Hillsboro, that typically means late spring through early fall for best results.
Avoid painting when rain is forecast within 24 hours. The paint needs adequate drying time, and our Oregon weather can be unpredictable even in summer. For more ideas on maximizing your garage space, read our guide on How To Organize Your Garage Without Blocking Your Door.
