Not all mesh is created equal Innovative glass fibre reinforcement mesh is now an integral part of modern render systems, with the days of chicken wire or stainless-steel mesh long gone.
Mesh should always be used when rendering to reinforce and strengthen against cracking. The incredible strength and flexibility of modern glass fibre works together with the latest flexible, breathable renders giving long term protection against cracking caused by movement. Compare this to tightly fixed rigid metal mesh – you can imagine how any small movement would cause render stresses and fractures.
How to use render mesh
The application and positioning of render mesh is often debated, where everyone will have their opinion – some fully mesh where as others may only mesh stress points and openings. Both are acceptable applications, but the product and substrate need to be considered as to how you apply the mesh, and take the manufacturers’ advice. As a company, we always say you can’t go wrong with fully meshing the render as it adds that little extra peace of mind.
How to choose render mesh
When it comes to choosing render mesh, not all mesh has the same qualities. Using a substandard render mesh can be the same as using no mesh. Look for two key properties:
- Ensure your mesh has a pressed weave. Render mesh that doesn’t have a pressed weave can become unstable and does not perform as well as a mesh that has been pressed, as the mesh can be pulled apart.
- Ensure your mesh is alkaline resistant. Render mesh without an alkaline resistant coating can break down in the render over time, leaving the render as if mesh was never installed.
Choose render mesh that has a pressed weave and alkaline resistant coating ensuring that they perform to the highest standard. All our grades of render reinforcing ProMesh
have these two key properties. We have 5 grades of glass fibre mesh suitable for internal and external wall applications and even floor screed and resin application. See more about ProMesh here
