How to Paint a Garage Door

Start With a Clean Surface

Wet the garage door and then spray with deck wash or scrub with TSP. Allow the deck wash time to work, as directed by the manufacturer. For either product, complete the cleaning with a thorough rinse. 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 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.

Patch and Prep

Scrape and sand any loose paint. For wood doors, any bare wood that looks gray needs to be sanded down or the paint won’t stay put.

Wood doors may also have cracks or holes that need filling. Apply caulk to these gaps with a putty knife to restore an even surface. Once dry, sand to smooth over where you have patched. Vacuum and rinse to remove any loose material and dust. Allow the door to dry completely.
