Fibreglass Mesh (165g/m²) – 10m²
Fibreglass Mesh is a key part of render and External Wall Insulation (EWI) Systems. It’s combined with a cement-based layer, like EWI-220 EPS Basecoat or EWI-225 Premium Basecoat, to make the final system both tough and flexible, adapting to natural building movements throughout the year.
Additionally, the mesh can be used for extra reinforcement in certain areas. For example, stress patches (300mm x 200mm) can be cut and placed at an angle around the corners of an opening to prevent cracking, especially in areas using traditional sand and cement.
When applying the mesh, ensure each piece overlaps the previous one, following the black marker on the mesh for guidance. For extra strength, you can use a ‘double-mesh’ technique: first, apply vertical strips of mesh, then add a second layer at a 90-degree angle. This might require a thicker basecoat layer (e.g., 8mm instead of the usual 6mm).
Though primarily used in basecoat layers of render or EWI systems, Fibreglass Mesh can also help repair cracks or strengthen floor screeds and plastered ceilings.
The mesh is treated with acrylic acid copolymer liquid, which makes it resistant to water, alkali, and ageing.

Frequently Asked Questions
- What is Fibreglass Mesh used for?
Fibreglass Mesh is embedded with the cement-based basecoat layer as this ensures the final render or solid wall insulation system is both strong (to withstand impact) and flexible to withstand natural building movements that occur during the different seasons.
- What basecoat should I use with Fibreglass Mesh?
We recommend using EWI-225 Premium Basecoat as it has a high concentration of polymer-modified binders and synthetic fibres, delivering flexibility, higher crack resistance, and improved durability. However, other basecoats, such as EWI-222P Performance Basecoat and EWI-220 EPS Basecoat Adhesive, can be used with fibreglass mesh.
- Does Fibreglass Mesh have any other uses?
Fibreglass Mesh can be used in areas that need additional strengthening to bridge cracks externally/internally or give extra strength to floor screeds and plastered ceilings.
- How do you apply Fibreglass Mesh as part of the reinforcement layer?
Fibreglass Mesh is embedded into the basecoat in vertical strips using the flat edge of a notched trowel. Each vertical strip of fibreglass mesh should overlap its neighbouring vertical strip by approximately 10-15cm.
- Do I need to use Fibreglass Mesh in my project?
Fibreglass Mesh is an integral component of render-only and external wall insulation systems. It allows the system to withstand impacts and natural building movements, reducing the risk of damage and hairline cracks.
