Intumescent coatings, often referred to as intumescent paint, are used in buildings as a passive fire resistance measure. They can be applied to structural members as an aesthetically pleasing fireproofing product.Click to see full answer. Keeping this in consideration, how does intumescent paint work?An intumescent coating is basically a paint-like material which is inert at low temperatures – under 200 ?C – but reacts with heat. As the temperature rises, during a fire event, the intumescent coating swells and forms a char layer that covers the steel.Secondly, how long does intumescent paint last? Steel: Intumescent steel paint is designed to increase the time period that a structural load bearing steel within a building will last during a fire. The paint works by intumescing or expanding to create an insulation barrier on the steel and increasing the time period to 60, 90 or 120 minutes. Additionally, what is intumescent steel paint? Application of intumescent paint layers helps fireproof structural steel, steel beams, steelwork or cast iron and can be used externally or internally, on small or larger areas. Intumescent coatings are generally available as water-based or solvent based variations (more information below).How do you make intumescent paint?Pour the gallon of paint into the clean 2-gallon bucket. Mix in your additive, using a paint stirrer to blend together. For powder additives, use 6 oz. to 1 gallon of paint for a Class B Fire Retardant Coating Rating. Use 12 oz. to 1 gallon of paint for a Class A Fire Retardant Coating rating.
