Plasterers meshes suitable for a wide range of applications within the context of building conservation, as well as contemporary plaster/render needs.

Glass fibre mesh fabrics are not only an important part of façade systems, but also interior plastering, because they prevent cracks and reduce the risk of mechanical damage to the surface. They are woven in what is called a Leno weave (a weave in which two warp yarns are twisted around the weft yarns to provide a strong yet sheer fabric) and typically referred to as meshes. The meshes are coated with an alkali resistant layer to protect the mesh during drying of the render.

Mesh fabrics are an effective, customized solution for the prevention of cracks that form in render which are induced by construction techniques, temperature changes and curing stresses. They can also be used for a wide range of repair applications, for example to bridge / cover any existing damage to wall surface.

While using mesh will mitigate many of the core issues to provide durable and appropriate renders, they do not negate the need for best practice such as good curing.

Cornish Lime have witnessed the evolution in this market over the years and having reviewed and trialled many different types of mesh decided to stock the ADFORS VERTEX® range from Europe’s leading manufacturer and processor of glass fibre yarns, who are part of the Saint-Gobain group, the world’s largest provider of materials and construction technologies. With high quality mesh you get ease of application, proven strength, cohesion and long-lasting crack resistance and mitigation with as high as a 60% reduction in cracking against no mesh.

Width is 1m. Lengths are available as 50m rolls or cut to length in 1m increments (add required length to basket and we will cut as one piece).

Widely used to reinforce walls, roofs, flooring and wherever insulation board is installed. It can also be used to reinforce cement, plaster, bitumen, plastics, marble and mosaic. Meshes are especially useful on high suction substrates such as Cob, Chalk, Brick and Rubble Walls. They also have a proven performance when used on wood wool boards.

Generally, exterior walls face more demanding conditions than interior walls. As a result, external meshes are designed with these conditions in mind, considering water penetration, wind impact, and broad temperature ranges. While it’s possible to use an exterior mesh internally, the specific requirements of your project and the material you’re applying will inevitably define whether this is appropriate.

The aperture of mesh refers to the gaps or holes in the mesh, which run lengthwise and across to create a woven material. The warp is the material running lengthwise, and the weft is the material running across.

Generally, heavier meshes have larger apertures, whereas lighter meshes have smaller ones. As a mesh’s weight in grams per square meter decreases, the aperture size also decreases, leading to more cross-points or intersections, compensating for the lower weight and ensuring reinforcement properties remain intact. When deciding on the appropriate aperture size, you can use the particle size of the render or plaster you intend to apply as a starting point. Smaller apertures are typically better suited for materials with smaller particle sizes, such as finer renders or plasters, while larger apertures are more suitable for larger particles, like coarse coat renders.

There can be multiple causes for cracks appearing in a render or plaster. Examples include substrate imperfections, temperature changes or curing stresses, building movement or settling, or stress in certain wall areas, such as window areas or partitions.
