Product Information

Full details

The Expamet Expanded Galvanised Mesh Coil is designed for professional contractors and DIYers needing to reinforce internal plaster over wall chases or dissimilar backgrounds. Its primary benefit is providing superior structural stability by preventing cracks in areas where different materials meet or where walls have been channeled. A key caveat to note is that it requires a minimum plaster or bed joint thickness of 10mm to function effectively and maintain proper coverage.

Extended Product Information

FAQs

Can this mesh be used outdoors?

This mesh is designed for internal plastering. For external applications, you should look for products specifically rated for high-exposure environments.

What tools do I need to cut this mesh?

Standard heavy-duty tin snips or metal cutting shears are recommended for trimming the mesh to size.

Does this mesh have any welds?

No, this is an expanded metal mesh with a continuous design, meaning it has no joints, interweaving, or welds.

What is the minimum plaster thickness required?

You must ensure a minimum bed joint or plaster thickness of 10mm for the reinforcement to work effectively.

How do I secure the mesh to the wall?

Use appropriate galvanised fixings or staples to secure the mesh firmly to the substrate before applying your plaster.

Troubleshooting

Mesh is buckling during installation

Ensure the mesh is pulled taut and fixed at consistent intervals to keep it flat against the substrate.

Plaster is cracking over the mesh

Verify that the plaster depth meets the 10mm minimum requirement and ensure the backing material in the chase has fully cured.

Pros and Cons

Pros

  • High durability due to 0.4mm galvanised steel construction
  • Seamless design eliminates risk of weld failures
  • Large 20m coil length covers significant surface areas
  • Effective at preventing cracks in plaster over wall chases

Cons

  • Requires a minimum of 10mm plaster thickness
  • Edges may be sharp during handling
  • Not intended for external environments without additional protection

Setup, Compatibility & Care

For proper setup, ensure the wall surface is clean and free of dust before fixing the mesh. Use suitable galvanised fixings to hold the mesh in place, ensuring it lays flat against the surface. The material is compatible with standard internal plastering systems provided the 10mm minimum thickness is maintained. To care for the product, store the coil in a dry environment to prevent premature oxidation of the galvanised coating, and always wear gloves when handling the mesh to avoid cuts from the expanded steel edges.
