How long does powder coating really last in NZ conditions?

Powder coating is durable, but in New Zealand, lifespan comes down to exposure. A building in Mission Bay ages very differently to one in Penrose.

Salt, UV, wind and moisture all wear at the coating over time. Inland surfaces can hold up for 15 to 25 years or more, while high-salt waterfront and high-rise sites often show breakdown in under 10 to 12.

We restore aluminium that was previously powder coated with advanced wet spray systems, bringing back protection when the original finish starts to fail.

A great piece of feedback from CMP’s Mark Crene for our aluminium joinery remediation work at Alexandra Park.

It’s great to have both the finished result and the team’s effort recognised.

Read his full testimonial below.

“Thanks very much for the great job you and your team have done here at Alexandra Park Building A, remediating all the aluminium joinery. The Matte Black aluminium joinery has come up looking fantastic thanks to your high-quality workmanship.

We appreciate the huge logistical effort it has taken to complete all the work in such a demanding timeframe, including your whole team working some big weekends.”

What happens when moisture gets behind a facade coating?

A facade coating does more than improve how a building looks. It protects the aluminium joinery, steel and architectural panels underneath from weather and everyday exposure.

When moisture gets behind that coating, the surface can start to deteriorate from the inside out. The first sign is often small: a bubble, a peeling edge, a patch of discolouration. Beneath the surface though, moisture may already be weakening adhesion or starting corrosion.

Painting over it rarely holds. A fresh layer can hide the problem for a while, but it doesn't restore the failed bond underneath, so the blistering tends to return.

Caught early, it can be the difference between a localised repair and a full facade refurbishment.

Can aluminium joinery be refinished while a building is still occupied?

In most cases, yes.

Our on-site refinishing process is staged in sections, with access coordinated around tenants and building operations to help minimise disruption.

Before work begins, we inspect the joinery to confirm refinishing is the right option. From there, the process includes:

→ Preparing the existing aluminium surface
→ Repairing worn or corroded areas
→ Masking the glazing and surrounding finishes
→ Applying the new coating by spray
→ Completing a final quality check

For aluminium joinery that is fading, chalking or showing signs of age, refinishing it in place can be a more practical and cost-effective option than full replacement.

To find out whether your joinery can be restored, contact us on 0508 732 656 or [email protected]

The longer you wait on facade maintenance, the more expensive your options get.

Aluminium joinery, powder-coated finishes and facade panels fade, chalk and corrode slowly, so nothing looks urgent until suddenly it does.

And that slow decline is the trap.

A surface you could have refinished this year, quietly crosses the line to full replacement.

And replacement costs more, disrupts more and wastes more.

Reactive maintenance means paying for that on someone else's timeline: urgent access, rushed budgets, tenants dealing with the fallout.

Planned maintenance means you catch surfaces while they're still restorable, stage the work around how the building runs, and control what it costs.

The building isn't going to tell you when it's time.

By the time it looks like it needs the work, the cheapest fix is already behind you.

We'd rather assess a facade while restoring it is still on the table.

Get in touch on 0508 732 656 or [email protected] before that choice gets made for you.

Before & After

Our Rosedale project shows just how much of a difference ACM refurbishment can make.

Rather than replacing the existing ACM panels, our team refinished the original cladding, restoring the appearance and giving the building a fresh, like-new finish at a fraction of the cost of replacement.

A simple transformation that has completely refreshed the look of the building.

If your building is starting to show its age, get in touch with the team to discuss your refurbishment options on 0508 732 656 or [email protected].

Working across large-scale commercial projects means being able to meet the pace, standards and expectations of the teams involved.

Our work with Fletcher Construction on the PwC Tower at Commercial Bay was a great example of this, with our team recognised for being well-organised, professional, clear on H&S requirements and able to meet strict construction deadlines throughout the project.

Read Ben's Full Testimonial below:

Fletcher Construction engaged WRNZ on Commercial Bay Tower based on the previous work within the construction industry. WRNZ completed a wide range of paint scope across the Commercial Bay project including sprayed wooden oak doors on-site which involved using a purpose-built spray booth and completed these to a factory finish, high standard to the architects requirements. Facade mullions, transoms, flashings, door frames and electrical trunking – these were resprayed in-situ saving the hassle and cost of replacement and meeting the required standard of finish. From start to finish WRNZ proved to be an exceptionally well organised team with a clear understanding of the H&S requirements for the products they used and a professional business to engage with. They continuously met strict construction deadlines and were a pleasure to work with.

Your building's facade won't last forever, but there will be signs before it gives up.

Here are some key signs your facade may be approaching the end of its service life:

🔸 Fading, chalking, peeling, or blistering coatings

🔸 Water staining around windows or panels

🔸 Mould growth or persistent condensation

🔸 Cracked or brittle sealants, or separation at joints

🔸 Loose or corroded fixings

🔸 Oxidation on aluminium surfaces

When coatings break down, underlying materials lose their protective barrier, leaving them exposed to corrosion, moisture, and the elements.

The good news? If caught early, refurbishment is often still a viable and cost-effective option. If you're starting to notice these signs, get in touch with the team at 0508 732 656 or [email protected].

Why replace when you can refurbish to your exact vision and save up to 70%?

Full panel replacement comes with a hefty price tag: demolition, new installation, and consents all add up fast. Our ACM refurbishment service restores your panels to like-new condition at a fraction of the cost.

Our solutions are also fully customisable so you can choose from a wide variety of colours and finishes to match your branding or refresh your building's look entirely.

To learn more about what we can do for your building, contact us at 0508 732 656 or [email protected].
