A new method of applying fire protection coating to structures results in a new type of fire protection coating 10. Insulation layer 20, preferably a vermiculite/gypsum mixture 26, is applied such as by spraying a water slurry of the mineral particles to structural member 85. Before the free moisture can evaporate, diffusion barrier 40, such as epoxy intumescent coating 44, is applied over the moist vermiculite/gypsum mixture 26. Moisture is retained within vermiculite/gypsum mixture 26 indefinitely and is released in the event of a fire to help cool and prolong the efficacy of intumescent coating 44.
