Aluminum Sidings are popular cladding material covering a wide range of applications from industrial to commercial construction projects. Due to aluminum siding’s various advantages, including extreme weather durability, minimum maintenance requirements, and aesthetics, designers prefer to utilize them instead of choosing other types of cladding materials. These sidings can last for a long period of time, but when buying a home with aluminum sidings facades, customers may encounter surfaces with peeled paint. However, this issue should not be a concern, and by using some painting supplies and elbow grease, painting these products will not be a daunting task. Thus, it is more cost-effective to paint the material rather than replacing it with a new siding. The painting process is relatively straightforward, and most homeowners can do it without professional assistance.
Equipment and Tools Required to Paint Aluminum Sidings
There are some few tools and pieces of equipment that are necessary to complete the aluminum siding painting process, including:
- oil-based primer- for sealing any porous surfaces and allowing the paint to cover the aluminum siding better
- acrylic exterior paint- for better bonding on the aluminum
- synthetic fiber brushes- are the only brushes that are practical when working with acrylic paint
- lambswool paint roller- can maximize coverage of the surface area
- ladder- for reaching and having access to the higher parts of the cladding
- plastic paint bucket- are helpful when using a ladder during the job since the painter can hang it nearby using its handle
- plastic paint trays- are necessary for paint rollers
- drop cloths- are used for keeping the area clean
Steps to Paint Aluminum Sidings
Some essential steps should be followed precisely when considering doing the aluminum siding painting without any help from experts, which we will introduce in this section. Each stage has its unique role in the process overall. Thus, if the painter perfectly finishes all phases, the aluminum siding will regain its beauty.
First Step: Prepare the Aluminum Sidings for Painting
Similar to any renovation application, painting aluminum sidings require preparation. This stage starts with scraping off paints that are already peeled by using paint scraping tools. Then it is essential to remove any noticeable mildew by utilizing a combination of ten parts water to one part bleach. If the aluminum siding is particularly dingy, it is better to buy or even rent a power sander to sand down the material. Experts recommend using eighty grit sandpaper for the first round, followed by 220 grit sandpaper for the second-round sanding.
Second Step: Apply the First Coat of Primer Paint Aluminum Sidings
The second stage is to apply the first coat of primer precisely. The painter must plan to begin the painting process when the weather is dry and mild for preventing rain, debris, and dust from destroying the finish. The process is more straightforward to do by using a paint roller and applying the primer evenly, rolling back and forth twice the roller for achieving a smooth surface. This procedure will take a few seconds per 0.09 square meters. It is crucial to work in one direction during primer applying, whether from left to right or right to left to maximize the drying time and help the painter work more efficiently.
Third Step: Applying the Second Coat of Primer
Now that there is already a first layer of primer, the painter must add the second coat. However, this must be done after the first layer is dried. Primer often takes about three to four hours to dry thoroughly. Thus, it is better to plan the process day accordingly.
Fourth Step: Start to Paint Aluminum Sidings
It is essential to use long and even brush strokes while painting from top to bottom during the process. In this way, it is possible to adjust any drips along the way. For better results, it is better to paint in the same direction as the aluminum siding, meaning if the product is horizontal, the painting course should be left to right, and if the siding is vertical, paint it up to down. If there is any sign of visible lines in the paint, the painter is doing the job too slowly. Taking breaks in between each side will ensure a smooth and finished surface.
Fifth Step: Add a Second Layer of Paint
After waiting a minimum of two hours, it is time to apply the second layer of paint. This stage can help the painter to correct any mistakes or flaws that occurred during the fourth step. For instance, any bumps present in work can be removed by using the sanding system. It is better to buy more paint than the painter thinks are needed. An extra gallon can be practical for additional coat or touchups, if necessary.
Sixth Step: Inspect the Work for Finding Issues
Once applying both coats of paint is finished, the finish must be left to dry for at least two hours. Then the painter must check and inspect the work, looking for spots that may be missed, drips, and bumps. If there is a sign of the old aluminum siding finish beneath the paint, consider applying one more layer of finish to ensure the process is done in the best quality.
