Aluminum awnings are a popular feature in many homes. The canopy-like structures are installed over windows and exterior doors. They also make good deck covers. This creates shade from the elements. Awnings over windows help to minimize infiltration of sunlight into the room. You get a cooler interior which enhances energy efficiency.

Aluminum is a popular material for awnings because of the ease of installation and affordability. The awnings are also very low maintenance. It is a good idea to paint your aluminum awnings to prevent corrosion. This helps to extend the life of the awnings. It also makes maintenance easier. With the guide below, it is easy to spray paint your aluminum awnings.

Step 1 - Clean with Soapy Water

Mix some mild detergent and warm water in a bucket. Wash the awnings with the help of a scrub brush. Rinse off the dirt and debris with a water hose.

Step 2 - Address Stains

You may spot some mold and mildew stains on your awnings. These can be effectively cleared with bleach. Mix 1 cup of bleach and 3 cups of water in a bucket. Place the solution in a spray bottle. Spray over the stained areas and allow the solution to work on the stains for about 10 minutes. Wipe the area with a damp sponge. If the stain persists, repeat application of bleach solution and leave on the stains for 10 minutes. Spray some more bleach solution and allow another 10 minutes for the stain to clear. Rinse with plain water and allow the awning to dry well.

Step 3 - Sand

Use an emery cloth to smooth areas of the awning that feel rough when touched. When the metal feels smooth and is shiny you can stop sanding. Rinse the awning with clean water and allow it to dry well.

Step 4 - Tape

Paint can easily splatter onto areas around the awning. Tape these areas with painter’s tape that has a wide width. It helps to ensure that you work neatly and efficiently. Tape also minimizes the clean-up after you’re done. Cover nearby flowers, plants, and grass with plastic sheeting. This helps to protect the vegetation from bleach and paint which may endanger plant life.

Step 5 - Apply a Primer

Obtain an oil-based metal primer for application to the awnings. It helps to ensure proper attachment of paint when you apply it later. Spray an even coat of the primer onto the awnings. Allow 24 hours for the primer to cure before you spray paint.

Step 6 - Spray Paint

Hold your spray can paint about 10 to 14 inches from the awning. Spray the awning with a thin coat of paint in long, even strokes. Let the paint dry for the stipulated time before you apply another coat. The acrylic paint helps to preserve the shiny look of your aluminum awnings.

Step 7 - Finish

Remove all tape. Collect the plastic sheeting and discard. Use some fine sandpaper to clear any spray paint that seems to be misplaced. Rub gently to clear the excess spray paint.
