Intumescent Coatings
Passive fire protection to buy time and save lives
Intumescent and cementitious coatings provide passive fire protection for structural steel, helping maintain structural integrity during a fire. This slows heat transfer, supports safe evacuation, and assists buildings in achieving required fire resistance ratings and Code of Compliance.
Our experienced team applies certified systems to achieve building Code of Compliance and meet industry fire rating requirements.
What we do
We apply intumescent coatings and cementitious fireproofing systems to structural steel in commercial and industrial environments, delivering compliant passive fire protection solutions.
Our services include:
- Fireproofing systems that meet New Zealand Building Code and project fire rating requirements
- Certified application of approved intumescent and cementitious coating systems
- Experience working in complex, high-risk, and live environments
- Rigorous QA processes, dry film thickness (DFT) checks, and digital reporting for compliance
We deliver end-to-end fire protection coating systems, including surface preparation coordination, application, inspection, and final documentation.
Systems we apply
We work across a broad range of certified intumescent and cementitious systems, selected to suit the substrate, fire rating, and environment:
- Epoxy and solvent-based intumescents — including International/AkzoNobel Interchar 3120 and Interchar 212, Jotun SteelMaster 1200HPE, Dulux Protective Coatings FIRETEX Platinum and Platinum‑120, and Fireshield 920KS
- Thin-film acrylic and waterborne intumescents — including Carboline/Nullifire SC601 and SC802
- Cementitious fireproofing — including Carboline/Nullifire Pyrocrete 40 and Isolatek Type 300
We have extensive experience delivering intumescent and cementitious coatings for passive fire protection on major infrastructure projects.
For example, at the Auckland Civic Administration Building, working for Naylor Love, we delivered structural steel fireproofing and corrosion protection across the tower. During the project, our scope expanded to include remediation of lead-contaminated coatings and full passive fire protection works, ensuring compliance and programme continuity in a complex refurbishment environment.
We also played a key role on the New Zealand International Convention Centre (NZICC) over 7 years, completing approximately 20,000 m² of fireproofing and protective coatings using Altex Coatings systems (Carboline and Nullifire products). Following the 2019 fire, our scope shifted to full remediation works, including complete removal of coatings by abrasive blasting and the application of a new multi-coat protective system.
