What is the best way to paint aluminium windows?

Painting aluminium window frames is a cheaper alternative to removing the entire set. The key to a successful paint job is preparation. Give the window frame a thorough clean with a brush and vacuum cleaner, making sure to remove all forms of dust and debris both inside and out. If there are weather seals attached to the window frame these must be removed as well.

 

Masking off the area around the window with painter's tape and a plastic drop sheet will prevent over spray from marking your wall. Putting a canvas drop sheet will protect your floor while spraying. With proper preparation, you should be able to achieve excellent results. - EricL

 

Bunnings has helpful D.I.Y. Advice on How to update window mullions. I would certainly encourage you to use some high quality painter's tape and take the time to cover an area as wide as possible with drop sheets so you don't have to repaint anything. - Jason

 

 

 

We are renovating our home and I have spray painted our aluminium windows from blue/black to white. When I sprayed my very first window I was nervous but after a while you will get the hang of it. - Sooze

Can you also do this using a brush?

Hi @littlej,

 

Yes, you can definitely use a brush to paint aluminium windows, but it's worth noting that a spray or a short-napped roller will generally provide a smoother finish with fewer visible brush marks. When using a brush, it’s important to choose a high-quality, angled brush to help with precision, especially around edges and corners. Be sure to apply thin, even coats to avoid visible streaks or texture.

 

If you’re looking for the best results, I would recommend using a spray, as it allows for a more uniform coverage, especially if you’re working with larger or more intricate frames. However, if you prefer to use a brush, make sure to work in small sections and allow each coat to dry thoroughly before applying another layer. Either way, with proper preparation, you’ll achieve a great result.

 

Please let me know if you have any questions.

Thanks @MitchellMc Our main issue is wall paint on the frames. Is there any way of removing this without sanding an repainting?

Hi @littlej,

 

One method is to use a solvent like acetone, which can help break down the wall paint without being too harsh on the original finish. Apply the solvent with a soft cloth or sponge, and gently rub the wall paint off. It’s important to test it in an inconspicuous area first to ensure it doesn’t affect the underlying paint.

 

If the paint build-up is minimal, you could also try using a heat gun to soften the paint, allowing you to scrape it off carefully with a plastic scraper. This approach should prevent damage to the original paint while removing the unwanted layer.
