90 Mins Fire Resistance  

This category lists intumescent paints and coatings for structural steel members that can provide fire resistance for up-to 90 minutes in the event of exposure to cellulosic fire. They will react to the heat from a fire by expanding the intumescent paint film thickness to form a protective char layer of differing depths, dependant on product.

Please check product descriptions for fire rating compliance, application methods – brush, roller, or airless sprayer - colour options, and product compatible system recommendations – primers, basecoats, or topcoats.

Intumescent Paint for Steel disclaimer: Always ensure the product you are purchasing is suitable for the intended use/project. This will include but is not limited to gaining clarification that the product in question can achieve the required fire protection for the steel sections and environment you have. The sub-categories within the Intumescent Paints for Steel section allow users to filter by internal or external use, on-site or off-site application, and product type – water-based, solvent-based, epoxy-based and MMA-based. These are to be used as a guide only as there will be instances where a product will be able to achieve 90min protection on certain steel section sizes but not others, or where it is suitable for external use in environments up to C4 but not C5-M for example. For further product, project and pricing support, we ALWAYS recommend you contact our Technical Department before purchase and use.

Fire protection doesn’t have to be hard work, let our technical staff help you get the level of protection you require and the finish you want. If there is a product you cannot find, please contact our Technical and Sales Support Team on 0113 245 5450.
