Nullifire SC902 ‘Fast Track’ Hybrid intumescent basecoat was selected for use on the heritage structural steel components at 5 Martin Place Sydney.
Originally built in 1913 to house the Commonwealth Bank Building headquarters, 5 Martin Place in Sydney’s CBD went through a comprehensive redevelopment, which retained the heritage component of 10 levels and added 9 new levels of premium office space. The heritage component was completely modernised without disturbing the distinctive features.
Nullifire SC902 intumescent basecoat was selected for the heritage structural steel components due to the unique surface tolerant properties of the coating. The coating was applied on-site to steel that had minimal surface preparation due to its previous encasement in concrete ceiling beams and required a 120-minute FRL performance.
The rapid, high build and fast cure capabilities of Nullifire SC902 provided the level of productivity required to deliver quick access to other trades that followed. The thin film coating allowed sufficient clearance for positioning of services to the underside of ceiling areas, which had very restricted heights.
