Product Description:
The ARDEX UD 158 Seam Reinforcement Mesh Strip is a professional-grade solution designed to strengthen and stabilize seams within uncoupling and drainage system installations. Built for compatibility with ARDEX UI 720 Flexbone floating membranes, this self-adhesive mesh tape ensures secure bonding at seams, joints, and cut areas, delivering a continuous and reliable substrate for tile and stone finishes. Its alkali-resistant composition makes it ideal for use with cement-based mortars, maintaining integrity even in challenging environments.
This reinforcement mesh is particularly valuable when working with complex layouts that require cutting the membrane around obstacles such as columns, cabinetry, or irregular surfaces. While Flexbone membranes include integrated mesh for long, continuous runs, the UD 158 plays a critical role in reinforcing shorter seams and cross cuts. By bridging these transitions, it preserves the structural consistency of the system and prevents weak points that could compromise the installation over time.
Installation is straightforward and efficient. After cutting the membrane as needed, simply apply the UD 158 mesh over the seam and embed it into a layer of modified thinset mortar using a trowel. Press the mortar firmly into the mesh to ensure full coverage and adhesion. Once set, the reinforced seam becomes a durable, integrated part of the underlayment, ready to support tile installation with confidence.
Beyond reinforcement, the ARDEX UD 158 contributes to the overall longevity and appearance of tile systems. By reducing the risk of efflorescence, staining, and discoloration, it helps protect natural stone and tile surfaces from common moisture-related issues. This makes it an excellent choice for exterior applications such as patios, decks, and balconies, as well as interior spaces where durability and performance are essential.
Whether you are a professional contractor or a skilled DIY installer, the ARDEX UD 158 Seam Reinforcement Mesh Strip provides a dependable and easy-to-use solution for achieving strong, stable, and long-lasting tile installations. Its combination of durability, ease of use, and system compatibility makes it an essential component for high-performance uncoupling and drainage projects.
