Application Conditions
- Nullifire SC802 is recommended for application and use on dry protected structural steel only.
- If the basecoat is allowed to get wet, it is likely to be damaged – blistering and wrinkling may occur.
- SC802 should only be applied when the air and steel temperatures are above 5°C. Relative humidity should be below 80% for successful application. Steel surface temperature should be a minimum of 3°C above the dew point.
- Ensure the steel is dry and free from contact with rain or condensation during the application and drying of SC802.
Surface Preparation & Priming
- SC802 should be applied onto a clean, undamaged, dry and primed steel surface.
- Certain types of primers can cause char adhesion problems in a fire. In particular, thermoplastic primers must be avoided.
- Nullifire recommend and have tested PM015, PM019 and PM020 primers – see website for details.
- Nullifire have carried out compatibility testing on a wide range of primers. Contact our technical team for details on compatibility.
- SC802 should not be applied directly to galvanised surfaces or zinc rich primer.
- The primer must be applied in accordance with the manufacturer’s instructions.
- Nullifire should be consulted for technical advice when zinc rich primers or the overcoating of existing paints are specifed for use.
