Spraying Diamond Grille Security Screens: A Professional Finish for Tricky Surfaces

Our expert spray painting process transforms diamond grille security screens with a durable, factory-style finish. See how we clean, prime, and repaint aluminium screens for a modern look.

Refinishing Diamond Grille Security Screens—The Right Way

Diamond grille security doors and screens are a common feature across homes on the Gold Coast, Brisbane, and Northern NSW. They provide security and ventilation, but over time, they can become faded, chipped, and weathered. Fortunately, replacing them isn’t your only option.

At RepaintPro, we professionally repaint diamond grille aluminium screens to restore their appearance and extend their lifespan. Using our specialised airless spray system and proven painting process, we give these difficult surfaces a clean, modern, long-lasting finish—without brush strokes or patchy coverage.

In the video above, you’ll see the priming stage of this process, which is key to making the paint last and bond correctly. This door, like all our jobs, follows the same method we use for aluminium windows, doors, garage doors, and fencing.

Why Spray Painting Works Best for Diamond Grilles

Diamond grille security screens are particularly challenging to paint properly. Their intricate mesh and overlapping patterns mean brushes and rollers simply can’t reach every angle—and even if they could, the result would be thick, uneven, and full of brush marks.

That’s why we use airless spray painting, which:

Delivers a smooth, even coat to all surfaces Reaches tight corners and mesh joints Avoids thick build-up or clogging the grille Leaves no brush or roller marks

This professional application method results in a factory-style finish that looks sharp and holds up against the elements.

Our Step-by-Step Process for Painting Aluminium Security Screens

We treat security screens with the same care and precision as we do with aluminium windows. Every job follows a strict preparation and application process designed for long-term durability and a flawless finish.

1. Surface Preparation and Cleaning

We start by cleaning the security screen thoroughly. This includes:

Removing dirt, grease, and contaminants Rinsing off any salt build-up (common in coastal areas) Lightly abrading glossy or powder-coated surfaces to promote adhesion

Proper cleaning is essential. Paint won’t bond to dusty, oily, or weathered surfaces, and skipping this step is the fastest route to peeling or flaking later on.

2. Masking and Protection

Before spraying begins, we carefully mask off the surrounding areas. This includes:

Edges of the door frame Handles, locks, and hinges Nearby walls or floors

We take pride in maintaining a clean job site and ensuring the only thing we paint is what was meant to be painted.

3. Etch Priming

As shown in the video above, the priming stage is where everything begins to take shape. We use a specialised aluminium etch primer designed for non-ferrous metals like security screens.

This primer:

Bonds deeply into the metal Creates a stable base for the topcoat Prevents flaking, bubbling, or lifting later

It’s quick-drying but critical to the longevity of the paint system.

4. Application of Finish Coats

Once the primer has cured, we apply two full finish coats of premium exterior-grade acrylic paint. You can choose between:

Low Sheen – For a subtle, matte look Semi-Gloss – For a slightly richer finish with added durability

The spray application gives the grille a flawless, even coat on every visible surface—from mesh patterns to frames—without clogging the airflow holes or creating heavy build-up.

Why Customers Choose to Repaint Security Screens

Many homeowners are surprised how much of a difference repainting security screens can make. Often, the screens themselves are still structurally sound—they just look dated or worn out. Repainting them:

Adds value and curb appeal Saves money compared to replacing with new Matches the colour of new windows or garage doors Offers a fresh, clean look for decades-old fixtures

Whether you’re going from white to black, matching new aluminium window colours, or simply refreshing the original tone, our process brings your screens back to life.

Suitable for Doors and Windows Alike
