Ipe

Bison 2′ x 2′ smooth Ipê wood tiles are commercial grade, constructed from responsibly harvested hardwoods, and available with standard or FSC® certified species. Bison wood tiles weather over time, developing a silvery-gray patina. If maintaining the natural wood color is desired, wood tiles can be periodically cleaned and sealed.
Note:  Wood is a natural product and actual tile colors may differ from photo.
