Also disclosed is an antimicrobial sacrificial floor coating remover being readily capable of removing the antimicrobial sacrificial floor coating as desired from previously treated flooring surfaces. In certain aspects, the antimicrobial sacrificial floor coatings can include a nonionic acrylic polymer; a nonionic wax; and a cationic alkyl biguanide or salt thereof. The antimicrobial sacrificial floor coating may further include a cationic wax that further stabilizes the system during storage, application, and/or post-application to a floor surface. The antimicrobial sacrificial floor coating composition has a pH of less than 7 while exhibiting continuous antimicrobial properties from full cure on a floor surface up to 1 year post-application to the floor surface at a minimum contact time of 1 hour. ## Claims ### Claim 1 An antimicrobial sacrificial floor coating composition comprising: (a) an acrylic polymer;
