Queensland is known for its tropical weather, it’s what makes it such a great holiday destination. Sadly, however, it is also a factor that can play havoc with construction. When it came to the application of a fire-rated product for the under-construction Townsville Hospital, North Queensland’s tropical weather conditions dictated that Nullifire SC902 would be the only intumescent coating capable of withstanding significant rain events without adverse impact on performance.
With early water resistance within one hour of application, tolerant of humidity of 85%+ and 8 hour cure times, the choice was simple.
With torrential rains caused from Cyclone Ita & Cyclone Marcia in 2014 the client was extremely impressed with the early water resistance capabilities of Nullifire SC902. The client had previously experienced the failure of other sprayed fire protection such as vermiculite, when it had been subjected to water leaking through floor decks and perimeter steel exposed to rain. This had caused lengthy delays in the building program, but these problems were no longer an issue when using Nullifire SC902. But most excitingly, this was the first project in Australia to use Nullifire SC902.
The application of the intumescent coating system to achieve a 120 min FRL was a seamless process with minimal disruption from prevailing weather conditions.
Only Nullifire SC902 will remain and not wash off in rainy weather events. Nullifire SC902 1 v Cyclone Ita & Cyclone Marcia 0.

The Use and Need for Penetration Sealing
In modern structures and buildings various specialised and technical installation services for power supply, computer and cable networks, transportation of water and sewage, and so on are installed as part of the build. Usually, these services penetrate fire separations in areas that are normally hidden away; above ceilings, through walls and other cavities. Because penetrations […]
What Makes a Good Fire Protection Coating?
As with all things in life, there are multiple opinions on what makes something good. When it comes to fire rating, there is no single treatment which everyone agrees on either. Some people focus on price, others on ease of application, others on suitability for conditions. And others again, on some combination of all these and more.
At Permax, we have our own beliefs, and we’re going to share them with you.
The Difference Between Engineers and Fire Engineers
Fun fact for your next trivia night: the term “engineer” derives from Medieval Latin and the word “ingeniare”, which means to design or devise. Ever since the wheel was invented (and even before that), humans have been devising clever inventions, designed to astound, improve, or carry out a function that too often we all take […]
