How to Paint a Garage Door (DIY) Family Handyman

Introduction

Learning how to paint a garage door, with all of its angles and panels, may look intimidating. But with a methodical approach, you'll have it done in a day!

Start with a clean surface

If you are looking to give your garage door a new lease on life, there is no easier way than preforming some simple garage door maintenance and covering it with a fresh coat of paint.

Start by removing all the dirt and grime. Wet the garage door and then spray it with deck wash. Allow the deck wash time to work, as directed by the manufacturer. Then, complete the cleaning with a thorough rinse and allow the door to dry completely.

Some people prefer to clean with a power washer. In most cases this is not necessary, but can be done with careful attention to pressure. Too much pressure or working too close to the surface can dent metal, score wood and remove the primer coat.

After washing the garage door, thoroughly rinse any nearby plants to remove any cleaner that may have settled on them. Plants that get splashed with cleaner will turn yellow.
