A process is described herein for applying antimicrobials to substrates to prevent the growth of biological agents. An antimicrobial-binder mixture is provided. The binder comprises guar gum, ammonium sulfate, urea, and methyl acryloid. The antimicrobial is an organo silane quarternary amine antimicrobial. The antimicrobial-binder mixture is ionized to comprise negatively charged particles. The antimicrobial-binder mixture is aerosolized to form fog. The fog is administered to the surface and dried.
