Abstract
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.
Claims29
A method of protecting a structure from fire by applying a layered insulating coating to structural members;
- including the steps of:
- applying a moist layer of insulation containing free moisture to a structural member of the structure;
- and
- covering the insulation containing free moisture with a diffusion barrier to maintain the insulation in a moist condition.
In combination:
- a structural member of a structure, and
- a fire protection coating attached to said structural member;
- including:
- a moist insulation layer containing free moisture;
- and
- a diffusion barrier covering said moist insulation layer, for preventing loss of free moisture from said moist insulation layer.
A fire protection coating for structural members including:
- a moisture-containing insulation layer attached to a structural member;
- and
- a diffusion barrier layer covering said moisture-containing insulation layer to prevent loss of moisture from said insulation layer.
