rep-L’s antimicrobial additive rep-L can be added to the final coating applied to the tile. This coating can be applied by the manufacturer, or either before or after the installation of the tile. In the case of concrete tile rep-L can be added to the cement blend, allowing for the coating to be integral to the tile. This tile can be used to cover floor or wall surfaces of hospitals, laboratories, food services, or everywhere, where a clean and germ free environment is required. The antibacterial tiles inhibit the growth of microbes, thus reducing microbial contamination and contribute to create a healthier environment in living and working spaces.
