High Impact Mesh
Heavy Duty Reinforcing Fiberglass Mesh (15.0 oz)

225 ft² (20.9 m²) per roll (38")


High Impact Mesh is an alkaline coated fiberglass fabric which is suitable to work as reinforcement for polymer modified and polymer-based cementitious base coats, and used as a heavy-duty mesh layer in all Durex® EIFS Systems and Durex® Stucco Lite System. High Impact Mesh is produced on a loom using warp and weft (fill) yarns and woven into a leno weave, where the fill yarns are trapped tightly between to twisting wrap yarns, and is then treated by alkali-resistant macromolecule latex for superior performance.

  • Fiberglass mesh of tested quality, capable of withstanding high tension without stretching.
  • Glass fibers with negligible sensitivity to temperature changes within the wall.
  • Proper fiberglass anti-alkaline dressing to avoid quick aging of the wall reinforcement due to corrosion action of alkalis present in coating mortar.
  • Provides dimensional stability and enhances performance.
  • Prevents cracking.
  • Good cohesion.
  • Flexible.

Heavy Duty Reinforcement Mesh for the base coat layer in all Durex® EIFS Systems when very high levels of impact resistance are required. Heavy Duty Reinforcement Mesh for Durex® Stucco Lite System. Heavy Duty Reinforcement for crack bridging in masonry substrates.
