Can You Paint Aluminum Siding?
Posted on June 14, 2022
A popular choice post World War II, aluminum siding requires very little maintenance and has great insulation and weather protection qualities. Although a cheap and durable material, it is prone to dents and fast-fading paint. A quick coat of paint will keep your aluminum-clad home sparkling!
Since there are different types of siding, each material requires different preparation and painting. Learn more about wood siding below!
How to Paint Aluminum Siding
Step 1: Prep the Surface
Inspect the aluminum siding and scrape off any peeling or flaking paint, as well as any old caulk lines. Scrub away any mildew and grime with warm, soapy water. Alternatively, using a power-washer will speed up this process, just be careful not to get water behind the aluminum siding. Let dry for 2 or 3 days before you start painting. Without thorough prep, the paint finish will bubble up, peel or fade faster than intended resulting in you having to do another painting project.
Step 2: Prime the Surface
A galvanized metal etching primer will give you the best results when painting your aluminum siding. You’ll want to use a synthetic polyester paintbrush to cover the full surface area and let it cure for at least 4 hours.
Step 3: Paint
Using 100% acrylic exterior paint, use a brush to paint the edges first before loading your paint roller. Run the roller in the direction the siding is oriented (side to side if horizontal, up and down if vertical), working your way from the top to the bottom. Let the paint dry for at least 2 hours before applying another coat.
