Aluminium window frames are common in Perth homes built from the 1970s onwards. Over time, the factory finish on aluminium frames can fade, chalk, peel or simply look dated. Many Perth homeowners wonder whether painting aluminium window frames is a practical option or whether replacement is the only answer.
The good news is that aluminium window frames can absolutely be painted, and when done correctly the result is durable, long-lasting and can completely transform the look of your home. Here is everything you need to know.
Can You Paint Aluminium Window Frames?
Yes. Aluminium window frames can be painted successfully with the right preparation and products. Aluminium is a non-porous metal surface, which means it requires specific primers and paints that are formulated to bond to metal rather than standard wall paints.
When the correct process is followed, painted aluminium frames look great and hold up well to the Perth climate including strong UV exposure, heat and occasional rain. A professionally painted set of aluminium frames can last 10 years or more before needing attention again.
Why Paint Aluminium Window Frames?
There are several good reasons to paint rather than replace aluminium window frames:
- Cost: Painting is significantly cheaper than replacing frames. Window replacement can cost thousands of dollars per window once you factor in the frames, glass, labour and plastering. Painting is a fraction of that cost.
- Appearance: Faded or chalky aluminium frames can make a home look tired. A fresh coat of paint instantly modernises the look of your home and can complement a new exterior colour scheme.
- Sustainability: Painting extends the life of existing frames rather than sending them to landfill.
- Property value: Updated window frames contribute to street appeal and the overall presentation of your home, which matters both day to day and at sale time.
How to Paint Aluminium Window Frames — The Process
Painting aluminium frames is not the same as painting walls. The process requires specific steps to ensure the paint bonds correctly and lasts.
Step 1 — Clean the Frames Thoroughly
All dirt, grease, oxidation and loose material must be removed before any painting begins. Aluminium frames are often coated in a layer of oxidation that looks like a white chalky residue. This needs to be cleaned back completely using a degreaser and a scrub, followed by a rinse and allowing the surface to dry fully.
Step 2 — Sand the Surface
The existing surface needs to be lightly sanded to give the primer something to grip onto. This is called creating a mechanical key. Skipping this step is one of the most common reasons painted aluminium fails — the paint simply peels off because it has nothing to bond to.
Step 3 — Apply an Etching Primer
A metal etching primer is essential for aluminium surfaces. This type of primer is specifically formulated to bond to non-porous metal and provides the foundation for the topcoat. Do not use a standard wall primer on aluminium — it will not adhere properly and the topcoat will fail.
Step 4 — Apply the Topcoat
Once the primer is fully cured, a quality exterior paint in the chosen colour is applied. For aluminium window frames we recommend a premium acrylic enamel or a two-pack polyurethane finish for maximum durability. These products provide a hard, washable surface that holds up well in the Perth climate.
Two thin coats are better than one thick coat. Each coat should be allowed to dry fully before the next is applied.
Step 5 — Masking and Protection
Before painting begins, all glass, walls and surrounding surfaces need to be carefully masked to protect them from overspray or brush marks. Professional painters use high-quality masking tape and take the time to get clean, crisp edges around each frame.
What Colour Should You Paint Aluminium Window Frames?
The most popular choices for aluminium window frames in Perth are:
- Dulux Domino — a classic off-black that works with almost any exterior colour scheme
- Dulux Lexicon Quarter — a crisp white that suits coastal and contemporary homes
- Monument or Basalt tones — dark charcoal shades that are very popular on modern and Hamptons style homes
- Matching the exterior trim — painting frames to match fascias, gutters and trims creates a cohesive, finished look

Can You Paint Aluminium Frames Yourself?
Technically yes, but the preparation and product selection are critical. The most common DIY mistakes are:
- Not cleaning or sanding the surface properly before priming
- Using the wrong primer — standard wall primers do not bond to aluminium
- Using low-quality paint that fades or peels quickly in the Perth sun
- Poor masking that leaves paint on the glass or surrounding walls
- Uneven application that looks patchy once dry
A professional result requires the right products, proper preparation and application experience. Most Perth homeowners who have tried to paint their own aluminium frames report being disappointed with the result compared to a professionally painted finish.
How Long Does It Take to Paint Aluminium Window Frames?
The time required depends on the number of windows and the condition of the existing frames. A typical Perth home with 10 to 15 windows generally takes one to two days including preparation, priming and two topcoats. Larger homes or homes with more windows will take longer.
How Much Does It Cost to Paint Aluminium Window Frames in Perth?
Costs vary depending on the number of windows, the size of the frames and the condition of the existing surface. As a general guide:
- A standard Perth home with 10 to 15 windows typically ranges from $800 to $2,000 for frame painting
- Larger homes or homes with more windows will be priced accordingly
- Additional preparation work such as heavy oxidation removal may add to the cost
