Fiberglass Seam Tape from G-Floor is a must-have installation accessory when you want a good-looking seam between two sheets of vinyl flooring. Made of strong fiberglass with an acrylic-based adhesive on one side (specifically made to work with polyvinyl material), this tape is installed by applying it to the underside of two mats, directly underneath the seam. This helps mitigate moisture seeping between the two mats, and anchors your mats together to avoid an unsightly joint. Create a like-permanent, durable bond between multiple mats with ease: this tape is easy to cut with a utility knife or scissors and is simple to install. The tape has adhesive on only one side, so it bonds on the underside without adherence to the floor. While the bond is strong, it's easy to cut the tape to separate your pieces of vinyl flooring. This tough tape's construction means it performs exceptionally well even in extreme cold and high heat: this tape won't stretch or split from environmental factors. For indoor or outdoor use, this is the best way to give your G-Floor vinyl garage flooring a seamless look while adding extra moisture protection to your subfloor. Packaged as a roll, this seam tape measures 4 inches wide and is available in 10 yd or 30 yd lengths, as well as black and white color.
