Spraying Final Coats of Lacquer on Aluminium Windows in Parkwood, Gold Coast

Introduction

On the Gold Coast, property owners are increasingly choosing to update the look of their homes and commercial buildings by repainting rather than replacing aluminium windows. One recent project in Parkwood demonstrates exactly how much of a difference careful preparation and spraying the final coats of lacquer can make.

At RepaintPro, we specialise in on-site aluminium spraying, and our methodical approach to applying final coats ensures windows not only look flawless but also stay protected for years to come. This blog post explores in depth how we spray lacquer topcoats, why they matter, and what homeowners in Parkwood (and across the Gold Coast) should know about the process.

Why the Final Coats of Lacquer Matter

The final coats of lacquer are not just about making aluminium windows look glossy or satin-smooth. They play several important roles:

Durability: Proper film build protects the frames against UV, weather, and corrosion.

Aesthetics: The lacquer enhances depth of colour, whether the chosen finish is gloss black, satin Monument, or a softer neutral.

Consistency: When applied evenly, lacquer eliminates patchiness and ensures a uniform sheen across every mullion and sash.

Longevity: With correct application, the topcoat will outlast cheaper alternatives and delay the need for future repaints.


In Parkwood’s climate—warm, humid summers with high UV exposure—the importance of a strong protective film can’t be overstated.

Preparation Before the Final Spray

No lacquer coat can succeed without rigorous prep work. Before we reach the stage of final spraying in Parkwood, the windows have already gone through:

1. Cleaning: Degreasing and washing down aluminium to remove contaminants.


2. Sanding: Mechanical abrasion to break down gloss and provide adhesion.


3. Priming: Application of adhesion primers that form the base film thickness.


4. Undercoating: Additional primer or first colour coats that establish a solid base.



By the time we are ready to spray lacquer, the windows are taped, masked, and the surrounding brickwork and glass fully protected. This attention to detail ensures the only thing receiving lacquer is the aluminium frame itself.

Equipment and Spray Technique

In Parkwood, we used professional HVLP spray guns set at the correct pressure (around 28 psi depending on gun and tip size). Key elements of technique include:

Spray Distance: Maintaining around 150–200mm from the surface for even coverage.

Overlap: 50% overlapping passes to avoid striping or patchiness.

Trigger Control: Spraying slightly off the frame, then releasing off again, avoids heavy build-up at edges.

Multiple Light Coats: We never “dump” one heavy coat. Instead, lacquer is applied in 2–3 controlled passes to build film thickness gradually.


This method prevents sags, runs, or orange peel while still delivering the correct microns of dry film thickness.

The Parkwood Project – Local Detail

Parkwood sits in the northern-central part of the Gold Coast, with a mix of established homes and newer developments. Many of the aluminium windows in the area are decades old, typically in faded cream, bronze, or yellowed finishes.

For this project, the homeowners wanted to modernise the look of their home without replacing windows. After priming and undercoating, the chosen finish was a deep satin black lacquer, which tied the windows neatly into freshly painted external walls and new landscape features.

The transformation was immediate. What once looked tired and dated became sharp, contemporary, and premium.

Controlling Environment and Conditions

When spraying lacquer in Parkwood or any Gold Coast suburb, conditions matter:

Wind: Excess wind risks overspray and dust contamination. We plan our spray times carefully.

Temperature: Ideal spraying occurs in moderate temperatures—too hot and solvents flash off, too cold and drying slows.

Humidity: High humidity can cause blushing (a white hazy finish). Correct thinners and timing prevent this.


Our team monitors weather closely and adapts with additives, gun settings, and drying times to keep results flawless.

Drying and Film Build

A key technical detail is film build.

Each coat of lacquer adds around 25–35 microns dry film thickness.

After two to three topcoats, the protective system builds to approximately 40–60 microns, ensuring strong UV protection and durability.


This is one of the major differences between professional spraying and DIY—many DIY jobs stop at a single thin coat, which will inevitably chalk, fade, or peel prematurely.

Addressing Myths About Lacquer Coats

There are a few common misconceptions we hear around the Gold Coast, and Parkwood was no exception:

Myth 1: Black paint lasts longer.
False. Durability depends on preparation, primers, and final coats—not colour choice.

Myth 2: One topcoat is enough.
False. Multiple coats are essential for correct film thickness.

Myth 3: Security screens cannot be painted.
False. Security screens and doors can be removed, prepped, and resprayed to match perfectly.


By explaining these points, we help homeowners make informed decisions rather than relying on shortcuts.

The Transformation – Before and After

In Parkwood, the final lacquer coats made the biggest difference. Before spraying, the windows looked flat, dull, and weathered. After the final coats:

The black satin sheen reflected light evenly.

The sharp edges of the frames stood out against fresh brickwork.

Every mullion and sash line looked like new.


Neighbours commented on how modern the home now appeared, without the cost of full replacement.

Benefits for Parkwood Homeowners

For homeowners across Parkwood and the wider Gold Coast, final lacquer coats bring several benefits:

1. Curb Appeal: Instantly adds value by improving first impressions.


2. Cost Savings: Repainting is a fraction of the cost of replacement.


3. Eco-Friendly: Reusing existing aluminium frames avoids landfill waste and the high carbon footprint of new manufacturing.


4. Longevity: With correct care, professionally sprayed windows can last many years before needing attention.
