The ARDEX UD 158 Seam Reinforcement Mesh is an essential product designed to connect and reinforce sections of the ARDEX 720 Flexbone Underlayment, especially when two pieces need to be joined after cutting. This high-quality mesh tape, measuring 4.25 inches wide by 82 feet long, is engineered to provide secure, stable connections across butted joins and seams, enhancing durability in ARDEX drainage systems like the ARDEX UD 150. The UD 158 is especially useful when merging two sections of the ARDEX 720 Flexbone Underlayment that have been cut along its 39-inch width. The Flexbone Underlayment itself features an integrated mesh on one side of the roll, which runs the full length of the membrane, making it convenient for connecting longer runs in straightforward installations. For instance, in a 14-foot room, two sections of Flexbone can be seamlessly joined along the 14-foot side using the built-in mesh, allowing for a streamlined and simple installation process. However, installation spaces are not always so straightforward. Often, obstacles such as bends, support poles, columns, cabinets, or other fixed features may interrupt the underlayment path, making it necessary to cut across the membrane’s width. In such cases, the ARDEX UD 158 Seam Reinforcement Mesh becomes invaluable, as it allows you to maintain stability and uniformity in areas where the underlayment has been split. For installation, simply cut the UD 158 mesh to match the length of the seam, then apply a modified thinset mortar onto the mesh using a trowel. Press the thinset firmly into the mesh to secure it, creating a reinforced joint that is ready for tile installation across the entire underlayment. The ARDEX UD 158 provides a dependable solution for complex layouts, ensuring a durable and professional finish, even in challenging spaces. Each roll of ARDEX UD 158 is sold individually, with pricing per roll available as listed.
