Painting the front door requires the special technique that provides lasting durability. Using a shop brush allows you to clean the dirt and dust that accumulates over time. Propping the door open allows access for taping the door seal, around the handles, and hinges for a crisp finish. Scrape any lose paint followed by a fine grit sandpaper to lightly scratch the surfaces off any imperfections and residue over time. Use a good painters tape to protect any glass inserts. Finally, you are ready to apply a coat of primer followed by a finish coat of your preference and color.
