Description
Render mesh is an alkaline-resistant, woven fiberglass mesh that reinforces plasters and renders, acting as an anti-crack and anti-shrinkage barrier to strengthen surfaces and prevent structural damage from movement or environmental stress. It’s applied by embedding it into the wet base coat of a render or plaster, providing incredible strength, flexibility, and tear resistance to areas like corners, joints, and entire surfaces. The mesh is crucial for stability, especially in exterior applications like External Wall Insulation (EWI) systems, offering long-lasting performance by resisting cement’s alkalinity and environmental fluctuations.
-
Reinforcement & Stability:
Provides a strengthening layer that increases the durability and stability of render and plaster systems.
-
Crack Prevention:
Acts as a high-tensile mesh to prevent shrinkage, movement, and stress cracks from forming.
-
Alkali Resistance:
Its alkali-resistant coating prevents the mesh from degrading when in contact with the alkaline components in cement and render.
-
Flexibility & Ease of Use:
The lightweight and flexible nature of the fiberglass mesh makes it easy to handle, cut, and apply to complex surfaces and corners.
-
Versatility:
Suitable for both internal and external applications on a variety of substrates including concrete, cement, screeds, and various carrier boards.
-
Durability:
Chemically inert and rot-proof, ensuring long-lasting performance even in demanding environments.
- Application: The mesh is applied to the first, still-tacky coat of render or plaster.
- Embedding: A second coat of render is then applied over the mesh, embedding it into the material.
- Reinforcement: The embedded mesh creates a durable, flexible lattice within the render, which absorbs stress and prevents cracks from propagating through the surface.
