If you've got outdated aluminum windows that you want to either restore the existing colour or you want to change the color, then, you can rest easy. You've come to the ideal location.

The procedure for aluminium Window painting can be broken down into a set of measures with two different stages. These are planning and program. The inexperienced however, will attempt to jump on the preparation to the detriment of the appearance and durability of the final product.


The amount of preparation required mainly depends upon the type and condition of the original substrate. For example, when you have old powder coated painted aluminum windows that has chalky paint and melts from your palms, then this will take a lot more prep than newer powder coated surface that's not chalking and has been painted for a color change.

However, anodized aluminium windows will take a lot more preparation than the rest of the substrates regardless of its substrate condition because, the surfaces need a lot more mechanical abrasion to key up the surface enough to permit the paint to stick.

Protection of adjacent finished surfaces- Whenever you are painting isolated part, it's important that you protect adjacent finished surfaces. When painting the aluminium windows in your home or apartment, you will want to think about placing plastic drop sheets down, followed by canvas fall sheets. I propose applying plastic picture and 3M, which you can using a hands dispenser to protect the glass and the walls directly surrounding the window frame.

Cleaning - Make sure all surfaces are clean and free of dirt. Grime and grease are crucial in the process of aluminium window painting. If surfaces are dirty then paint adhesion is reduced. Clean the frames on the outside with warm water and a sponge. But, use a detergent that is salt free such as truck wash.
Then, alternately down clean surfaces both indoors and outside with solvent wash such as prepsol.

Use a scour to apply the solvent. The scour will wash and key that the surface at the same time. It's important that you conduct a second solvent wash dirty windows by applying solvent using a sterile cloth then wiping off with another clean cloth.

Sanding the substrate - There is not any easy way around this process. This is sometimes difficult and monotonous particularly getting to the tighter spots like the upper channel since there's no mechanical sanding gear that can make the task a whole lot faster. Therefore, doing the work manually by hand is hard and time consuming.

If you have powder coated coating that is chalking, I would advise sanding with 120 grit. The sand paper is less likely to clog. If your substrate is powder coated and isn't chalking then 240 grit will be sufficient to key the surface particularly in the event that you have scoured it . However, if your property is anodized then you are in for some real work since you'll want to break the 60 grit sand paper. Take some masking tape ring aids for the ends of your fingers ready because this is where you are going to be more"rubbing your fingers to the bone"
Sixty grit will really split the anodized surface up. And you would need the paint to actually stick, right? Skip this and you are going to be doing the job all over again. As soon as you've completed this, it's best for you to go over the job again with 120 grit sand paper to smooth out the gouges caused by the 60 grit.

You're almost ready to begin the fun part, which is applying the paint. Before you paint a window give it another clean wipe using your solvent wash, don't forget to utilize two different clean fabrics.
