Product introduction

Fiberglass Mesh Corner Bead combines a rigid corner profile with alkali-resistant fiberglass mesh to reinforce external corners formed during plastering or rendering. The profile establishes a straight, uniform edge, while the mesh becomes integrated with the surrounding mortar or base coat. This combination is commonly specified for corners that require both dimensional accuracy and additional reinforcement.

How to use

Corners are exposed to different stresses than flat wall surfaces. During construction they are more likely to be knocked by tools or scaffolding. After a building is occupied, furniture, carts and routine maintenance frequently impact these areas. Even where visible damage does not occur, repeated loading can gradually weaken the plaster along the edge. Reinforcing the corner before the finish is applied generally reduces later repairs.

 

The profile is positioned on fresh plaster or base coat and aligned before additional material is applied. Mortar passes through the fiberglass mesh and locks around the yarn as it cures. Once hardened, the profile becomes mechanically connected to the surrounding wall rather than acting as an independent accessory. The rigid nose defines the corner line, while the mesh helps transfer localized stress into the adjacent render instead of concentrating it directly along the edge.

 

From what we have seen on renovation projects, failures around corners are often related to insufficient embedment rather than the profile itself. If the mesh is not fully covered by mortar, reinforcement becomes much less effective. Keeping the mesh completely surrounded by the base coat usually produces a stronger and more durable connection.

 

A consistent mesh structure allows the render to penetrate evenly during installation. This helps maintain good adhesion between the reinforcement and the surrounding plaster. The profile also serves as a practical guide during finishing, making it easier to achieve straight, uniform corners without repeated adjustment.

The fiberglass mesh corner bead is regularly used in cement rendering, gypsum plaster, EIFS and ETICS base coat systems, drywall finishing and refurbishment work. It is equally suitable for window reveals, door openings, column edges, balcony details and other exposed corners where maintaining edge geometry is important throughout the service life of the wall.

In commercial buildings such as schools, hospitals, offices and public corridors, reinforced corner details are often specified because these locations experience frequent contact during daily use. In residential projects, corner beads are commonly installed around entrance passages, stairwells and areas where furniture is regularly moved.

Storage is straightforward. Keep the profiles dry, protect the mesh from unnecessary deformation during transport and store the bundles on a flat surface before installation. During construction, align the profile carefully and ensure that the mesh is fully embedded within the plaster or base coat. The reinforcement performs as part of the wall system, so installation quality is just as important as the product itself.

We manufacture Fiberglass Mesh Corner Bead in different profile dimensions, mesh widths and roll combinations to suit a variety of rendering systems. PVC, galvanized steel and aluminium profiles are available for different applications. Custom lengths, mesh specifications, private-label packaging and customer branding can also be supplied where project requirements differ from standard production.
