Quality assurance for intumescent paint coatings
This, combined with well-designed inspection test plans (ITPs) from the blast and paint yards, plus the intumescent paint coating contractor, are critical to ensuring adequate fire protection from an intumescent coating system.
All structural steelwork needs to be documented with:
- Blast profile readings
- Primer dry film thickness (DFT) readings
- Intumescent basecoat DFT coating readings
- Top coat DFT readings
This should be done by an ACA paint inspector or an NACE qualified inspector.
All ITPs and quality-assurance documentation needs to be collected and securely stored to ensure compliance is both achieved and maintained.
There are several systems designed to collect and manage compliance documentation. A good example of such a program is Certifire which is designed and programmed in Australia to ensure it meets all relevant Australian requirements.

Intumescent coating types
There are a variety of intumescent coating types with different properties and application methods. Which type is the best for your situation?
Passive fire protection methods
There are several ways to protect building structural work. Whilst some methods may be more prevalent, there is no one "best way" to protect a building's structure. The best method will most likely be determined by a number of factors, but here are your options.
Off-site versus on-site application
Nullifire SC902 ‘hybrid’ intumescent coating system - one of our preferred ‘hybrid’ intumescent coating systems - is based on patented technology that delivers exceptional productivity gains for both on-site and off-site applications, in comparison with conventional intumescent coatings used for structural steel fire protection.
Intumescent paint coating specification templates
Access a range of templates supplied by manufacturers for the purposes of specifying their intumescent paint coating products for various FRLs and corrosivity ratings.
Intumescent paint coating corrosivity ratings in the Australian atmosphere
It's common knowledge that corrosion rates are affected by environmental factors, but do you know the various corrosivity ratings and their definitions?
Limiting steel temperatures to maintain structural integrity
Maintaining structural adequacy on load-bearing steel is critical to the fire safety of building occupants, fire fighters and the surrounding built environment. Here's how limiting steel temperatures to maintain structural integrity relates to intumescent paint coatings.
Getting help with intumescent paint coatings
The specifying and application of an intumescent coating system is a highly specialised task that requires considerable training and experience to accomplish correctly.
Fire types and severity
Different combustible materials burn at different temperatures which will have a bearing on the FRL of a given intumescent paint coating. This needs to be taken into account when specifying intumescent products so that the required FRL is ensured for the combustible materials that are likely to be encountered in a particular situation.
Specifying intumescent paint coatings
Whilst intumescent coating products may look just like paint, they have an important function (i.e. passive fire protection) that makes their specification a much more involved process.
How core filling affects intumescent paint coatings
Core filling is a viable solution to fire-protect high Hp/A hollow section steel that is otherwise unable to achieve the desired FRL.
