Intumescent Paint Contractors: Structural Steel Protection
Intumescent coatings, often referred to as intumescent paint, are a cost-effective and ideal solution to protect structural steel from the damage caused by fire. Intumescent coatings are designed to react to heat by expanding and creating a charred insulating layer around the substrate to protect the steel, and it’s load bearing properties in the event of a fire.
Flux Fire Protection provides intumescent paint for steelwork, offering 30 to 120 minutes of protection. We can offer our own specifications for a more cost-effective approach or work to our clients‘ specifications. Our team of dedicated employees work across the country offering bespoke intumescent paint services in Yorkshire, the Midlands, the North East and beyond.

Intumescent Coating FAQs
While ultimately dependent on a number of environmental factors, substrate condition, and specific product formulation, intumescent coatings can last up to 25 years. The life expectancy of coatings is shortened due to exposure to UV radiation, moisture, and temperature fluctuations.
Yes, you can paint over intumescent coats. However, due to the carefully-designed nature of fire-retardant systems, all components such as basecoats, primers and topcoats must be compatible.
Yes, intumescent coatings require space to expand. When exposed to high temperatures, the paint is formulated to expand to a number of times its original thickness, forming a carbon layer to protect the substrate.
