Intumescent Paint

Buildings and structures today have some degree of Passive Fire Protection (PFP) to protect lives by delaying possible structural collapse through the use of Intumescent paints on load bearing supports. This allows for evacuation in the case of fire, ensuring the integrity of escape routes for a predetermined length of time.

Intumescent Painting is Saving Lives

Intumescent paints or coatings are usually epoxy based, solvent free material and classified as thick film coatings, although they do exist as water based products also, these are typically thin film with dry film thicknesses of less than 5,000 microns. When exposed to fire, this form of Passive Fire Protection (PFP) expands to form an insulating char with low thermal conductivity acting as a barrier between the fire and the underlying substrate. During this reaction of epoxy intumescent coatings, toxic fumes and smoke are released usually at temperatures above 300•c which typically makes them unsuitable for indoor use or enclosed spaces. Epoxy passive fire protection should be applied to a correctly prepared and primed surface, providing then a high level of adhesion, resulting in far fewer mechanical damages. Intumescent coatings have been used to protect steelwork in structures for decades with a swelling and expanding action in the event of a fire creating a phyisical barrier between the steel and flames delaying a fires spread, for hours.

Intumescents Paint

Steel typically starts to loose its structural strength at temperatures above 400•C depending on its alloy composition. Intumescent paint applied by Dangle and our well trained and competent teams, delay the time it takes steel to reach this temperature, allowing time for personnel to evacuate to safety.

Passive Fire Protection Surveys

At times Dangle do accept requests to perform fireproofing surveys to evaluate the passive fire protection system that has been applied to a steel structure. We can provide fireproofing inspectors certified through the Institute of Corrosion to carryout condition surveys for warranty or general annual inspections.

Intumescent Paint for Steel

Passive fire protection is an integral part of fire safety. And a legal requirement, of course. Intumescent paint for steel swells up when heated, protecting the material underneath. It also seals small gaps that fire could otherwise pass through. This slows the fire down, giving building occupants more time for evacuation. By protecting the steel structures, it also reduces the chance of a building collapse. And protects firefighters in the process.


Intumescent and fire-retardant paints have an important difference. Fire-retardant coatings release gas as they heat up. This gas dampens the flames and stops them from growing. However, both are commonly used in fire protection.


Intumescent coatings for steel are available in solvent-based and water-based forms. (Although the former is more common.) They have several advantages. For example, they don’t affect the mechanical or other intrinsic properties of the materials. They’re easily applied. At Dangle, we deal mostly with intumescent paint for structural steel. But different kinds of intumescent paint can be used for other materials too.


Ablative coatings are also a form of fire protection. They’re designed to literally burn away, absorbing energy from the fire and protecting the structures beneath. Ablative coatings buy precious time in the event of a fire. However, they have other advantages too. They also contribute to thermal protection and acoustic insulation.


Passive fire protection also encompasses fire doors and other measures to slow a fire down. It works together with active fire protection. That means measures such as sprinkler systems and fire extinguishers. And fire prevention, which uses education to stop outbreaks before they even start.


Our team at Dangle combines the best in technical knowledge, with rope access expertise and practical experience. You can count on us to know the intumescent paint for steel building regulations, including primers and topcoats. We’ll get your project completed on time and on budget, meeting all the necessary safety and quality standards.


We’d advise you to start planning early. This will prevent delays if painters need access to structures that are already covered up. Thorough surface preparation and priming is key. It ensures the correct adhesion of the intumescent fire-retardant paint. Our specialist rope access technicians can access many difficult to reach areas - quickly and efficiently.


The Dangle team holds a comprehensive set of industry certifications. We’re members of the Institute of Corrosion (ICORR), the National Association of Corrosion Engineers (NACE) and the Chartered Quality Institute (CQI). We’re also accredited by the Society for Protective Coatings (SSPC) as training providers for ‘train the painter’ programmes. This means we have all the know-how to take your project from initial survey to final hand-off. Including intumescent fireproofing.


We hope you will rely on us for your next passive fire protection project. As you can see, Dangle offers a comprehensive set of commercial industrial painting services. We’re an award-winning and family-run business. And our smaller size and structure help us to offer a flexible and competitive service. Please get in touch today to discuss your project.
