Product Information

Full details

The Simpson Strong-Tie Masonry Reinforced Mesh is designed for professional builders and DIY enthusiasts seeking a reliable solution for internal plastering over wall chases. Its primary benefit is providing robust structural reinforcement to prevent plaster cracking in areas where materials meet or in wall channels, ensuring a durable finish. However, users should note that this product is specifically engineered for internal applications and requires careful installation to ensure proper adhesion to the substrate.

Extended Product Information

FAQs

Can I use this mesh for external wall rendering?

No, this product is specifically designed for internal plastering and may corrode if exposed to external environmental conditions.

What is the thickness of the mesh?

The mesh has a thickness of 0.4mm.

How should I fix the mesh to the wall?

The mesh can be held in place with appropriate masonry fixings or embedded into a base coat of plaster.

Does the mesh contain any welded joints?

No, the design is completely jointless, ensuring no weak points in the reinforcement structure.

What is the total length of the roll?

Each roll is 20 meters in length.

Is this suitable for covering large electrical chases?

Yes, the 175mm width is specifically designed to cover standard electrical and plumbing chases effectively.

Troubleshooting

Mesh is buckling during installation

Ensure the surface is level and the mesh is not being stretched too taut; use more frequent fixings to hold the edges flat.

Cracks reappearing over the mesh

Verify that the chase beneath was properly filled and allowed to dry before applying the mesh and final plaster finish.

Difficulty cutting the mesh

Use high-quality metal snips or dedicated wire cutters to ensure a clean, fray-free edge.

Pros and Cons

Pros

  • High structural integrity due to the jointless manufacturing process
  • Effective at bridging cracks in plaster over wall chases
  • Generous 20m length suitable for large projects
  • Excellent for stabilizing junctions between dissimilar backgrounds

Cons

  • Primarily limited to internal use
  • Requires proper cutting tools for precise installation
  • Edge handling can be sharp, requiring safety gloves

Setup, Compatibility & Care

To ensure optimal performance, the surface must be clean, dry, and free of dust or loose debris before application. Measure the chase or junction and cut the mesh to length using heavy-duty snips. Secure the mesh using mechanical fixings or embed it into a thin initial layer of mortar or bonding agent, ensuring it lays flat against the surface. Avoid pulling the mesh too tightly, as this can create tension that defeats its structural purpose. For care, store the roll in a dry environment to prevent corrosion, as the galvanised coating is intended for dry internal conditions and should not be exposed to prolonged moisture.
