Intumescent Coatings

Intumescent coatings are the tried and tested way of protecting buildings and ultimately people and lives. Our intumescent coatings have been exhaustively tested both in our own laboratories but also to national and international standards in independent testing houses all over the world.


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 S707-60 remains the preferred choice, and for longer time periods our new hybrid SC902 thick coat or SC801 are recommended.

Solvent-Based Intumescent Coatings

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


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.
