Main applications

Drywall Joint Reinforcement
Our fiberglass mesh tape is engineered for reinforcing joints between drywall panels. It helps prevent cracking and ensures a smooth finish, making it a reliable choice for wallboard seam treatment. The self-adhesive backing simplifies installation in both residential and commercial interior wall systems.
Crack Repair in Wall and Ceiling Surfaces
Ideal for reinforcing damaged areas, our mesh tape offers structural stability when applied over hairline cracks or surface breaks. It is commonly used in restoration and renovation projects where durability and long-term crack resistance are required.
Cement Board and Tile Substrate Support
In wet areas like bathrooms and kitchens, our fiberglass mesh performs well in bridging seams on cement boards or backer boards. Its moisture resistance and compatibility with cementitious compounds make it a preferred material in tile underlayment and waterproofing systems.
Plaster Surface Treatment and Wall Patching
The open-weave design of our mesh provides excellent bonding for plaster base coats. Whether applied under skim coats or used to reinforce patch repairs, it helps prevent shrinkage cracks and maintains surface integrity over time.
Moisture-Prone and Exterior Applications
Thanks to its alkali-resistant treatment, our tape performs consistently in humid environments and can be used under exterior renders or tile installations. It is particularly effective in areas exposed to moisture, where long-term adhesion and mold resistance are essential.

Features

Superior Alkali Resistance
Our tape is specially treated to withstand alkaline environments commonly found in cement and drywall compounds, ensuring long-lasting durability without degradation. This means less maintenance and longer service life for your wall repairs and joint reinforcements.
Strong Adhesion with Self-Stick Backing
Featuring a high-quality pressure-sensitive adhesive, the mesh tape adheres firmly to drywall, cement boards, and plaster surfaces. This easy-to-apply self-adhesive design reduces installation time and labor costs during drywall seam taping or surface patching.
High Tensile Strength and Flexibility
The woven fiberglass fabric provides excellent tensile strength, preventing cracks from spreading while allowing enough flexibility to accommodate minor structural movements. This makes it ideal for reinforcing drywall joints, plaster repairs, and cement board seams.
Breathable Open Mesh Structure
Its open weave promotes strong bonding with joint compounds or plaster, facilitating moisture evaporation and reducing the risk of mold growth. This characteristic improves the longevity of the drywall or plaster finish.
Moisture and Mold Resistance
With excellent waterproof properties, this fiberglass mesh tape performs reliably in humid or wet environments such as bathrooms and kitchens, making it suitable for both interior and exterior wall applications.
Versatile Compatibility
Designed to work seamlessly with various drywall tapes, cement board backers, and plaster materials, our fiberglass mesh tape adapts well to different construction and renovation projects, enhancing overall structural integrity.
