Summary:Jul 24,2026

Construction fiberglass mesh is commonly incorporated into plaster and cement-based systems, where exposure to alkaline conditions can be part of the application environment.

The coating system can contribute to the protection and performance of the glass fiber mesh.

When developing an alkali-resistant coating system, several factors may be considered:

  • Polymer binder selection
  • Adhesion to E-glass yarn
  • Compatibility with glass fiber sizing
  • Alkali-aging performance
  • Water resistance
  • Flexibility and stiffness
  • Coating add-on
  • Drying and curing conditions

The final performance of the coated mesh is influenced by the interaction between the glass fiber, sizing, polymer coating and processing conditions.

A formulation designed for interior plaster reinforcement may require a different balance from a formulation intended for ETICS or stone backing applications.

RUI CO works with water-based polymer technologies for fiberglass mesh coating and can assist with the evaluation of binder systems and coating formulations for different construction mesh applications.
