How to fix peeling paint on garage door.

In order to fix the peeling problem you have to eliminate the cause. Examine the steel garage doors carefully. Replace peeling paint flat sawn boards with boards that have vertical grain or sand all the paint off and coat them with a paintable water repellent before priming and repainting. That s a lot of time for our wood trim to be exposed to the elements.

Hold the can 10 inches from the door and work in slightly overlapping sweeping motions to avoid drips. Just use your paint brush to apply a small square of paint. Use a primer over bare wood. Scrape off the peeling paint with a paint scraper then sand down the door with your hand sander paying extra attention to the areas that were peeling.

Allow the primer to dry to the touch. Because of this the outside trim around the front doors garage door and the porch pillar were in pretty bad shape this spring. Apply a second coat of primer to the door and allow it to dry completely. But we found an easy solution to peeling outdoor paint without all the scraping and sanding.
