The present invention provides compositions for application to a material, such as building materials, prior to an exposure of the material to fire, or prior to, during or after exposure of the material to conditions favorable to the growth of microbes. When compositions within the present invention
The present invention provides compositions for application to a material, such as building materials, prior to an exposure of the material to fire, or prior to, during or after exposure of the material to conditions favorable to the growth of microbes. When compositions within the present invention are properly applied to a material, they have the effect of reducing the amount of burning that occurs to the material, and/or reducing the amount or density of smoke and associated toxic gases produced by the material, when the material is exposed to fire, and inhibiting the growth of microbes on the material when the material is exposed to conditions favorable to the growth of microbes. The invention also provides methods for reducing the burning of a material that is exposed to fire, and for inhibiting the growth of microbes on a material exposed to conditions favorable to the growth of microbes.
