Water-Based Intumescent Coatings

Nullifire pioneered water-based technology, which gives a smooth finish in a faster time than other methods. Given the environmental benefits of water-based coatings then these products are now the preferred choice among specifiers and applicators alike. For 60 minute fire protection Nullifire have now introduced SC802 intumescent coating which gives superior loadings over a wider range of section types, as well as being very easy to spray. For longer time periods up to 120 minutes our water-based SC801 product is recommend, or our high build SC902.

Our water-based systems include:

Solvent-Based Intumescent Coatings

For when environments are semi-exposed then solvent based  products still provide an answer in obtaining an excellent finish in a reasonable time frame.

Our solvent-based systems include:

  • SC601 Solvent-Based, Intumescent Base Coat
  • SC602 Solvent-Based, Intumescent Base Coat


For primers that work in harmony with protective intumescent coatings then look no further than these recommended solutions from Nullifire. All of these have been tested to enable them to be specified together with the confidence that they will perform both in application and in the event of fire.

Top Seals

Top Seals are the final element, designed to make the finished steel work look good, but also to protect the intumescent basecoat underneath. Always make sure that the top seal is compatible with the basecoat by selecting from the Nullifire range.
