Extending the Life of an Existing ACM Façade System

The Rosedale ACM refurbishment project focused on restoring the appearance, consistency, and long-term performance of an ageing commercial façade system.

WRNZ completed a full façade refresh designed to improve coating durability, restore visual consistency across the ACM panels, and extend the service life of the building exterior without requiring full panel replacement.

Using a tailored refurbishment methodology, the project addressed coating deterioration, environmental exposure, and surface ageing while delivering a clean, modern finish across the entire façade.

Project Scope

WRNZ carried out a comprehensive ACM façade refurbishment including:

  • Surface preparation and restoration
  • ACM panel refinishing
  • Coating system application
  • Colour consistency restoration
  • Protective exterior finishes
  • Building envelope rejuvenation
  • Long-term coating protection

The refurbishment process was specifically designed around the condition of the existing ACM system and the environmental exposure of the site.

Tailored ACM Refurbishment Approach

ACM panel refurbishment is rarely a one-size-fits-all process.

Every façade deteriorates differently depending on:

  • age of the coating system
  • environmental exposure
  • UV breakdown
  • maintenance history
  • substrate condition
  • coastal or industrial contaminants

Because of this, WRNZ develops a customised refurbishment methodology for every project.

Some ACM façades may only require surface restoration and refinishing, while others need more extensive preparation, corrosion treatment, substrate repairs, or specialised coating systems designed for long-term durability.

For the Rosedale project, the focus was on restoring the building’s exterior consistency while improving coating performance and protecting the façade against ongoing environmental wear.

Key Project Challenges

Commercial ACM refurbishment projects often involve several technical challenges that must be carefully managed throughout the process.

For this project, WRNZ addressed:

  • Existing coating deterioration
  • Surface ageing and fading
  • Maintaining consistent panel appearance
  • Environmental and UV exposure
  • Long-term coating adhesion
  • Protection of surrounding building elements
  • Minimising disruption to the commercial site

Detailed preparation and coating application processes were used to ensure a durable and visually consistent finish across the façade system.

The team at WRNZ were great. From the moment of contact, very clear quoting, watching the weather to schedule the job in and even returning on the weekend if needed. I have now had them back for several projects and highly recommend the quality of their work and organisational skills.

We have recently had remedial work completed on our home in Wellington. WRNZ provided an outstanding solution that has brought our home back to its original condition. Ben kept us in the loop throughout the process. He was extremely sympathetic to our position as homeowners and ensured the whole operation was stress free for us. The calibre and workmanship of his staff was first class. We are delighted with the result and have no hesitation in recommending WRNZ. Anne and Max McKegg

Contacted Ben to help me out with a powdercoating job that had failed. I cannot overstate how impressed I am by their professional attitude and hard working team. I have no hesitation in recommending them to family, friends or business colleagues in need of their services. My clients are also very impressed with the outcome and the minimal disruption involved getting the job done. Great job WRNZ!

Murray and the team did an outstanding job with painting our exterior aluminum joinery (windows & doors). They were quick, tidy and paint work finish is superb. Murray project managed and was onsite with the team every day and all matters were discussed and agreed, no surprises. Even with other trades on site, they accommodated and were very professional. Would highly recommend their service, workmanship and quality, well done!

I cannot recommend this team enough, the entire process of having them at our house repainting our doors was an absolute pleasure. They were super friendly, incredibly considerate, so easy to have around AND did an AMAZING job... we feel like we've got a new house, we're delighted. Thank you so much team, you were incredible and your work ethic is commendable.
