Should Aluminium Windows Be Sprayed or Brushed? | Gold Coast

When it comes to repainting aluminium windows, the method matters just as much as the paint. The two common options are spraying or brushing/rolling. So, which one is right?

Brushing Aluminium Windows

Some painters use brushes or small rollers because it seems faster or cheaper. But with aluminium, brushing has serious drawbacks:

Visible brush marks or roller stipple – aluminium frames are smooth; imperfections stand out.

Uneven coverage – corners and edges often look patchy.

Thin film build – one coat of brushed paint doesn’t provide lasting protection.

Messy edges – hard to get razor-sharp lines against glass and render.


???? Brushing might work on timber fences, but it doesn’t deliver a factory-style finish on aluminium.

Spraying Aluminium Windows

Professional HVLP spraying is the gold standard for aluminium windows and doors:

Factory-style finish – smooth, even, and consistent.

Sharp edges – masking and spraying produce clean sight lines against glass and walls.

Durable coatings – multiple thin coats create the correct film thickness.

No brush marks – the finish looks like the frame was manufactured that way.


At RepaintPro, we spray all aluminium frames using the same method trusted for shopfronts, offices, and high-end homes.

Why Spraying Is the Professional Choice

Aluminium frames are smooth and non-porous. For coatings to last, they need:

1. Thorough prep (cleaning, sanding, priming).


2. Multiple coats applied evenly.


3. Masking and spraying for precision.



Spraying is the only method that meets all three requirements.

FAQs – Sprayed vs Brushed

Q: Can aluminium windows be painted with a brush?
Yes, but the results are streaky, patchy, and often peel within months.

Q: Why do professionals spray instead?
Spraying produces a flawless, factory-style finish that lasts.

Q: Is spraying more expensive than brushing?
Not always. While spraying takes more preparation, it saves money long-term because the job only needs to be done once.

Q: Does RepaintPro always spray aluminium windows?
Yes. Every aluminium frame we do is sprayed with HVLP equipment for the sharpest finish.
