How to Refinish Aluminum Siding

Aluminum siding is a popular alternative to vinyl siding or wood shingles. Many homeowners who choose this material do so based on its durability and low-maintenance requirements. Aluminum siding holds up beautifully for 20 to 30 years, but after that point it typically needs to be refinished and repainted to regain its luster. For those that prefer not to hire a professional, refinishing aluminum siding can be a rewarding home improvement project that can really change the look of a home's exterior.

Instructions

Things You'll Need

• Aluminum siding pieces
• Galvanized roofing nails
• Hammer
• Powerwasher (Can be rented)
• Detergent
• Hot water
• Paint
• Primer(Like Emulsa-Bond)
• Paint sprayer

1. Remove any dented or badly damaged pieces of siding. Replace these pieces with new siding by cutting the new pieces to the proper size, inserting them in place of the old siding and nailing in place.

2. Power wash your walls using a commercial power washer, which can be rented from a home improvement store. Use a mild detergent and hot water to thoroughly clean any dirt and debris from your siding.

3. Allow the walls to dry completely. This may take a full day, depending on the whether and temperature in your area.

4. Mix one quart of primer with each gallon of paint you use for your siding. The chalky texture of worn aluminum siding prevents paint from adhering to the surface. This primer helps counteract the effect of the chalk and allows you to apply the paint more smoothly.

5. Apply the paint in smooth, even strokes using your paint spray gun. These paint sprayers are available for rent and are easy to use. Spraying your paint allows for a smooth, professional finish.

6. Wait 24 hours for the first coat of paint to dry, and then repeat Step 5.

Tips & Warnings

• Use a paint that is specially formatted for exterior aluminum siding, such as Sherwin Williams Exterior Enamel.
