Painting an aluminum soffit can be a difficult project. It is a DIY project you can do yourself, though, by following these steps.
Step 1 - Clean the Area
The most important thing to do before you begin the painting process is to clean off the aluminum soffit. If you begin with a dirty surface, the paint won't look good or last long. You can use a cleaner and a rag and rinse with water. Be sure that everything is completely dry before you paint. If you do have a really bad surface to start with, you may want to consider pressure washing.
Step 2 - Choose the Right Paint
Make sure that you put a lot of time and thought into choosing the paint. Look around and ask about exterior paint for aluminum. You need something that is going to look good and stand up to the weather. You may also want to consider adding a bonding agent to the paint to help.
Step 3 - Paint the Aluminum Soffit
Begin with a coat of primer and paint in one direction. Then, allow the primer to set and dry and paint on a coat of the exterior paint. Depending on the paint that you get as well as the color, you will want to paint on two to three coats.
