An antimicrobial coating composition is disclosed. The antimicrobial coating composition also includes a polymer having a plurality of alkene units and a plurality of macroCTA polymer units. The composition also includes one or more reactive silanes, one or more wetting agents, and one or more solvents. A method for applying an antimicrobial coating composition is disclosed. The method for applying an antimicrobial coating composition may include contacting a polymer, one or more wetting agents, one or more solvents, and one or more reactive silanes with one another to prepare an antimicrobial coating composition, homogenizing the antimicrobial coating composition, applying the antimicrobial coating composition to a substrate, and allowing the antimicrobial coating composition to dry at ambient conditions.
