A method to coat hard floor surfaces to provide both anti-slip and antimicrobial protection by producing clear, thermodynamically stable, anti-slip, botanical antimicrobial microemulsions made for all renewable, non-toxic, non-corrosive ingredients is disclosed, as well as their use as 1) highly effective antimicrobial broad spectrum disinfectants/deodorants that are not hazardous to humans or animals and simultaneously 2) as anti-slip coatings for any walked-on hard floor surface.
