A black binding tape is sewn around the mat for durability and to nicely frame the artwork. The mat has been permanently dyed for moderate traffic and can be placed inside or out (only under a covered space). Durable and fade resistant. The back of the mat is rubber backed to keep the mat from slipping on a smooth floor. Wash with high pressure from your garden hose or with a power washer. Use cleaner that does not produce suds.
