Intumescent coating or sealants swell up when heated (in a fire for example) and protects the material (steel or wood) underneath it, sealing a gap and making the surface fire retardant. As the intumescent layer swells up, it increases its surface volume, which then helps to decrease the intensity of the flames. The top coating produces a light char as it is burnt, which makes it a poor conductor of heat and the spread of fire. Application of intumescent paint layers helps fireproof structural steel, steal beams, steelwork or cast iron and can be used externally or internally, on small or larger areas.
