The Complete Guide to Repainting Powder-Coated Aluminium Windows Gold Coast

Why Powder-Coated Aluminium Windows Need Repainting

From the 1980s through the 2000s, most aluminium windows on the Gold Coast were supplied powder-coated. Powder coating was marketed as tough, durable, and “maintenance free.” But decades of UV, salt air, humidity, and general wear have proved otherwise.

Powder-coated aluminium eventually:

Chalks – a white powdery residue forms on the surface.

Fades – original colours lose depth and vibrancy.

Discolours – creams turn yellow, bronzes turn dull, silvers pit.

Breaks down – exposing aluminium beneath.


That’s why more homeowners are asking: Can powder-coated aluminium windows be repainted? The answer is yes — but it requires the right preparation and system.

The Challenge With Powder-Coated Surfaces

Powder coating isn’t like raw aluminium. It’s a baked-on finish that becomes slick and difficult for new coatings to grip. That’s why brush-on paints or DIY sprays often peel within months.

To repaint powder-coated aluminium successfully, you need:

Mechanical keying (sanding to roughen the surface).

Specialist primers that bond to powder-coated finishes.

Correct film thickness in primers and topcoats.

Professional HVLP spraying for even, factory-like finishes.

Our Proven System for Repainting Powder-Coated Aluminium

At RepaintPro, we’ve perfected a process that works across Gold Coast homes:

1. Surface preparation – Thorough wash, sanding, and degreasing.


2. Masking – Razor-sharp tape to protect glass, tiles, render, and decking.


3. Priming –

Norglass All Surface Primer: 30–40 microns DFT per coat, two coats = 60–80 microns.



4. Spraying –

Concept Acrylic Lacquer: 25–35 microns DFT per coat, total build 40–60 microns.



5. Multiple coats – Not just one thin coat, but a system build for durability.


6. Finishing touches – Tape removal, reinstalling flyscreens, cleaning frames.



This combination ensures new coatings bond to the old powder coat and stand up to Gold Coast conditions.

Why Powder-Coated Aluminium Fails on the Gold Coast

The local climate is harsher than many places powder coating was designed for:

UV exposure – Intense sunlight breaks down pigments and binders.

Salt air – Coastal suburbs like Palm Beach, Tugun, and Currumbin accelerate corrosion.

Humidity – Hinterland suburbs like Mudgeeraba, Bonogin, and Worongary challenge adhesion.

Storms – High winds and water drive moisture into weak coatings.


Without repainting, powder-coated frames degrade faster each year.

Popular Colours for Repainting Powder-Coated Aluminium

When updating powder-coated windows, most homeowners choose timeless colours:

Black – Sleek, modern, and blends into the glass.

White – Bright and classic, ideal with shutters and curtains.

Monument – A strong, versatile dark grey.

Surfmist – Light, coastal grey-white.

Ironstone – Deep neutral that complements stone and timber.


From our projects, 99% of powder-coated resprays are black or white, with Monument, Surfmist, and Ironstone completing the list.

Why Spraying Beats Other Methods

Some companies attempt to paint powder-coated aluminium with brushes or rollers. That always leads to:

Visible brush strokes.

Uneven film builds.

Short lifespans before peeling.


Spraying is the only method that delivers:

Even coatings at proper microns.

Factory-quality finishes that look like new manufacture.

Durability built for the Gold Coast climate.
