An intumescent basecoat from Nullifire was specified for use on the heritage structural steel components at the Old Commonwealth Bank Building in Sydney. A historically significant structure located at 5 Martin Place, Sydney, the building is popularly known as ‘The Money Box’.

Nullifire SC902, a fast track hybrid intumescent basecoat was selected for use on the heritage structure due to the unique surface tolerance properties of the coating. The Nullifire SC902 hybrid intumescent basecoat is specifically formulated to provide optimal fire protection on interior or exterior steel. A low VOC single coat system, the SC902 offers fire protection for up to 120 minutes.

The coating was applied on-site to steel that had minimal surface preparation due to its prior encasement in concrete ceiling beams, and required a 120-minute FRL performance. The rapid, high build and fast cure capability of Nullifire SC902 provided the level of productivity required to deliver quick access to the trades that followed the treatment process.

The thin film coating allowed sufficient clearance for positioning of services to the underside of ceiling areas, which had very restricted heights.
