The fiberglass mesh acts as a reinforcement of the plaster and prevents haircracks and clefts caused by movements of the underlying elements(bricks, prefabricated or lightweight blocks etc.) or by external agents. The mesh width can vary according to the granulometry of the plaster: rough plasters require wider mesh, fine renders have to be reinforced with finer mesh.
