Over time, rough weather and other conditions can wear your garage and cause it to look old. If you want to make over your old garage door, paint it. This will make your garage door good as new, and you’ll be able to customize it to the color you’d like. As long as you know the correct tools and painting techniques, the task is simple.
Sand the door down to remove all excess debris and leftover paint from the previous paint job. Use 80-grit sandpaper.
Wipe away any excess dust from the wall that the sander may have left behind, using a rag.
Apply an even coating of exterior satin paint in the color of your choice. Use a 4-inch-wide flat-headed paintbrush. Allow the paint to dry completely. If the color isn't as bold as you'd like, apply an additional coating.
