G-Floor Seam Tape is used to join two polyvinyl floor mats together at the seam. Apply this tape to the underside of your mats for a strong, lasting bond. made from strong fiberglass cloth with an acrylic adhesive that creates a like-permanent, durable bond between multiple mats. The tape has adhesive on only one side, so it bonds on the underside of your floor mats without adherence to the floor. Once installed, seam tape can be cut without damaging your polyvinyl floor mats. G-Floor Seam Tape won t stretch in high heat and withstands extreme cold. Seal seams and seal out water indoors or outdoors with G-Floor Seam Tape.
