Carbon mesh can be applied in two different ways: external reinforcement and internal reinforcement.
External reinforcement - the mesh is impregnated with an epoxy resin and bonded to the exterior surface of the structure being reinforced. This method does not add load to the structure, has low weight, and allows for subsequent finishing of
the reinforced surface.
Internal reinforcement - the mesh is embedded into the repair compound Xwrap CemiRepair. This method is suitable for masonry structures. It does not require additional fire protection measures. Carbon mesh combined with the repair compound, when used as internal reinforcement, has a non-combustible classification (fire resistance group NG). The substrate where the carbon mesh is to be applied must be properly prepared. In reinforcement areas, existing plaster, coatings, and paints must be removed, and the surface degreased.
The surface must be structurally sound; damaged areas should be repaired. Before applying the mortar, dust must be removed from the substrate using an industrial vacuum cleaner, and the surface should be moistened to a matte-wet condition
without leaving any water streaks or droplets. When applying the mesh with a mineral binder, water and dry mix are thoroughly blended in a clean container. The repair compound is applied with a smooth metal trowel in a layer at least 3–4 mm thick. Before the layer sets, embed the carbon mesh into the freshly applied mortar. Next, apply a covering layer with a thickness of at least 2–3 mm to fully encapsulate the mesh.
