Choosing and installing a plastering grid is an essential step in improving the external appearance of your home while maintaining both functional durability and aesthetic appeal. Plastering grids, sometimes referred to as reinforcing meshes, are essential for supporting the plaster or stucco that is applied to facades. It ensures the longevity of your external finish by distributing stresses and preventing cracks to provide structural integrity.
Plastering grid selection involves taking into account various aspects like mesh size, material, and compatibility with the type of plaster or stucco you intend to use. Fiberglass and metal are two common materials used to make these grids; each has varying degrees of strength and flexibility. The final plastered surface’s texture and smoothness are influenced by the mesh size, which also establishes the distance between grid elements.
The careful process of installing the plastering grid starts with surface preparation for the facade. In order to guarantee correct adhesion, the substrate must be thoroughly cleaned, eliminating any dirt or impurities that can weaken the plaster’s bond. Depending on the substrate and grid material, the grid is carefully cut to size and firmly affixed using the proper fasteners or adhesive after the surface has dried and cleaned.
A flawless finish can only be attained by making sure the grid is installed correctly. Plaster layer gaps and weak points are avoided by properly aligning and overlapping mesh panels, particularly around corners and edges. Careful attention to detail during installation improves the facade of your home not only in terms of appearance but also in terms of weather resistance and long-term structural integrity.

What types of reinforcing mesh are
The external deposits are strengthened by using the plastering grid for exterior work. The following elements are necessary in order for such nets to be manufactured:
- stability to alkalis and corrosion;
- a light weight;
- strength;
- Durability of operation.
Metal, glass fiber, and plastic are used in the manufacturing of reinforcement nets. Areas where the plaster layer will be thin are best suited for classes with small cell sizes (no larger than 6 × 6). Plaster up to 5 cm thick can be applied with material that has an average cell size of 13 x 15 m. Additionally, if the cells are large (22 × 35 m), this type of grid is used in broad areas or when processing an uneven facade where thick layers of construction mixture application are necessary.
Metal
Metal grids include wire-twater (wires with small diameters used to support thin beams of material), wicker, sampled-exhausted (holes made on a steel sheet), and welded (very durable).
Strong steel is the foundation of a plastering mesh that is dependable and extremely strong. They will be applied specifically in areas where a thick layer of plastering solution needs to be applied. Steel wires are welded together and then stretched to create the welded grid. Sheet steel is employed in the manufacturing of exhaust and sampling nets. It has a rhomboid form with holes in it.
A corrosion-resistant galvanized metal mesh is also present.
Plastic
Universal nets for reinforcement include nets made of plastic or polypropylene. They are reasonably priced. Sturdy but non-severe materials withstand moisture, do not decay, and react with chemicals as well.
Plastic nets are categorized into multiple groups based on their unique characteristics.
- Shintoflex – very strong and resistant to deformation of the plastic brand;
- Armaflex – enhances masonry, used to plastered uneven surfaces;
- Plurim – the chemical inertia of the material is high;
- Stren – it is mainly intended for an aggressive environment.
Plaster layers that are no thicker than 5 cm are typically reinforced with plastic nets. Furthermore, a high density grid can tolerate a solution layer as thick as 30 mm. Plastic nets come in a variety of colors, but orange, blue, and green stand out in particular. Additionally, there are two brands: PCF (figurative rhombus cells) and SQ (square-shaped cells).
Crucial! When used as a reinforcing mesh on a gypsum construction solution, plastic nets work well. since the alkalis in cement have the power to demolish its structure.
Fiberglass
Melted glass that has been saturated with specific substances is used to create fiberglass nets. Fiberglass strength rises in this way. Stable temperature fluctuations in a glass fiber grid. A fiberglass mesh with a cell size of at least 5 × 5 m is an effective way to reinforce facade plaster.
Plaster nets are made by impregnating fiberglass with a particular polymer that is resistant to alkalis. It is advised to use synthetic fiberglass reinforcing mesh for plastering facades with layers no thicker than 3 cm.
There is a shell grid in the fiberglass group. 3. The material used for residential wicker is elastic and long-lasting.
Which grid is better for facade plaster
It is advised to pay close attention to the breakdown indicator when choosing the facade grid. If the plastered surface is level, 1800n grids are available for purchase. Additionally, you must use a grid between 1300 and 1500 n when processing curved, uneven areas where a thick layer of the construction mixture is needed.
The fiberglass grid works well for creating a finishing cladding or finish where the plaster cover should not be thicker than two to three centimeters. Additionally, it works well when applying the black coating.
Using a steel grid is successful when the plaster layer is 30 mm thick. The element that will interact with the reinforcing material must also be considered. For instance, steel may corrode when it comes into contact with moisture, which causes corrosion spots to appear.
Plastic meshes can withstand damp conditions, but heat can cause the material to distort. As a result, the general qualities and application area must be considered when choosing the material.
For your exterior work, selecting and putting in place a plastering grid is essential to guaranteeing the durability and visual appeal of your home’s facade. Choosing the appropriate plastering grid type based on the particular needs of your project is the first step in this process. Think about things like the finish you want, the local climate, and the substrate you will be using.
The right installation comes next after selecting the suitable plastering grid. Start by giving the facade’s surface a thorough cleaning. In order to do this, the area must be cleaned, any cracks or flaws must be fixed, and the substrate must be stable and appropriate for application. In order for the adhesive to properly adhere to the plastering grid, the surface must be properly prepared.
Apply the plastering grid according to the manufacturer’s instructions. Using the suggested mortar or adhesive, firmly attach the grid to the ready surface. For a consistent, polished finish, pay close attention to the grid’s spacing and alignment. Before beginning any additional exterior work, give the curing time the manufacturer specifies enough of time to pass.
Last but not least, maintaining the plastering grid after installation is crucial to preserving its longevity and aesthetic appeal. Frequent upkeep and inspections can assist in spotting any problems—like cracks or detachments—early on and enable prompt repairs. To improve the grid’s resistance to weather conditions and extend its lifespan, think about adding a sealant or protective coating.
Plastering mesh selection and installation are essential for creating a long-lasting and aesthetically pleasing facade during exterior renovations. Plastering mesh serves as a layer of reinforcement, strengthening the bond between the plaster and substrate and preventing cracks. The type of plaster and the external conditions of the building should be taken into consideration when choosing the mesh, along with aspects like material strength and mesh size. A smooth finish is achieved through careful plaster application, secure mesh attachment, and meticulous surface preparation during proper installation. Plastering mesh is an essential component of exterior renovation projects because following these steps guarantees the durability and aesthetic integrity of your home’s exterior.
