What are the different types of intumescent coatings?
Although there are many different brands of intumescent paints and each brand has a large number of products within their ranges, all intumescent paint products can be categories of product, shown in the table below.
A couple of notes to the table:
- Volatile organic compounds, or VOCs, are substances containing carbon that easily become vapours or gases. They can be present in paints, coatings and cleaning products. In coatings, they assist with the quality of application and drying. They can cause respiratory and other health problems for occupants when used indoors. Their release into the indoor atmosphere is called off-gassing and it occurs over time, not just during application or drying.
- Comparative costs are based on a project with a 120 minute fire rating level.

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.
Quality assurance for intumescent paint coatings
We believe Painting Contractor Certification Program (PCCP) accreditation is paramount for passive fire protection contractors engaged in applying intumescent paint coating systems.
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.
