Nullifire SC804 On-Site Water-Based Intumescent Basecoat, a water based intumescent coating used for internal structural steel to C1 and C2 environments that can be top coated with a suitable topcoat for decorative and durability purposes.
Nullifire SC804 On-Site Water-Based Intumescent Basecoat is a water-based, white, thin film intumescent coating for the protection of internal structural steelwork, developed to give optimised loadings for up to 90 minutes, and up to 120 minutes fire resistance.
SC804 is a water based intumescent coating used for internal structural steel to C1 and C2 environments; the coating can then be top coated with a suitable topcoat for decorative and durability purposes. If SC804 is to be used on exterior exposed steelwork, it must be top coated prior to exposure, and care taken that no standing or pooling water is allowed to accumulate.
SC804 can be applied to a smooth matt finish. A compatible top seal can be applied if a decorative finish is required.
Use in well ventilated conditions and ensure all recommended protective equipment is worn during handling & use of this product. For full recommendation, refer to the safety data sheet.

Once DFT’s have been achieved as specified, a Nullifire top seal can be applied: TS134 (acrylic polymer), TS815 (modified acrylic) or TS816 (water-based acrylic), can be applied. Ensure the SC804 is completely dry before applying top seal.
Damaged areas should be abraded back to a sound surface. The surface should then be clean and dry before re-applying. FC101 Filler may be used for repairing scratches and chips. Once repaired topseal should be re-applied. Refer to Nullifire Maintenance Instructions.
