Specifically an intumescent paint is a coating that reacts to heat by swelling in a controlled manner to many times its original thickness producing a carbonaceous char formed by a large number of small bubbles that act as an insulating layer to protect the substrate. The fire rating is determined by the number of mils of fireproofing applied. The result is that the hard layers make it more difficult to heat the materials underneath. . Though less accurate than a gauge, you can also estimate your WFT by taking the DFT of a finished area and plugging it into the following calculation: (Square footage of area x DFT / Percentage of paint solids by volume). Fire ratings require certain degrees of paint thickness, called Dry Film Thickness (DFT) and Wet Film Thickness (WFT). Like DFT, you can check WFT with a wet film thickness gauge.
