Fire Resistant Coatings and Paint Additives Call Now For Free Consultation - Flame spread classes, roofing classes and fire hourly ratings are confusing terms and they sometimes get misused. Class ratings and their associated flame spread ratings are Class Flame spread Class "A" or I: Class "B" or II: Class "C" or III: Remember, this rating applies only to a specific single component such as a paint film, wall covering or some other single piece of material. It's vital to know that the hourly ratings have no reference whatsoever to real-time hours in an actual fire and they are NOT assigned to any one single component of a complete assembly such as a paint coating, wall covering or other single building material. Simply put, there is no such thing as a paint coating, additive or treatment that can be applied to any and all wall or ceiling configurations which will give a 1, 2 or 3 hour rating. Paint related fire treatment products offer several advantages over untreated wood and other combustible materials, they do not ignite or contribute to the spread of flame and some, Intumescent coatings, will insulate the surface from the heat for a short period of time by swelling up and expanding when exposed to flame, producing a heat resistant charred surface. This fire retardant paint additive can be added to any interior latex paint for a Class "A" or Class "B" fire rating.
