Plastering mesh is one of the most vital tools in a plasterer’s toolbox when it comes to finishing walls. The plaster’s ability to stick well and hold up over time is greatly dependent on this mesh.
Plastering mesh strengthens the plaster layer and helps to prevent cracks. It is particularly useful in locations where there is movement in the wall surface or where various materials come together. Without it, the plaster might not function as planned, requiring later, expensive repairs.
This post will discuss the various kinds of plastering mesh that are available, their functions, and the reasons they are so important for giving your walls a smooth, durable finish.
Appointment
For external decoration, plaster is covered with a galvanized mesh, which adds extra protection against the material’s adverse environmental effects.
The product can also be used indoors for plastering surfaces. Even a novice finisher can apply the solution more easily thanks to the material.
The field of use
Galvanized metal plaster is utilized:
- when installing floors with heated;
- for reinforcing the building base during finishing;
- to strengthen structures;
- to protect various mechanisms;
- for the construction of fences and enclosures.
Plaster layers depend on the plasterer’s mesh for support and stability, making it a vital tool for wall finishing. On a variety of surfaces, it guarantees a smooth, long-lasting finish and helps prevent cracks. Your wall projects’ longevity and quality can be greatly increased by realizing the value of this material.
Material functions
The functions of galvanized plaster mesh are as follows:
- Increases the strength of the plaster by reinforcing the surface. The metal strengthens the material and improves the resistance of the product to mechanical damage. The result is a kind of reinforced concrete structure that can withstand even increased loads and significant impacts.
- Binds the solution, preventing cracks and peeling, which increases the operational period of the finish.
- Increases the adhesive properties of the material. The solution adheres to the surface, as well as to the metal. The mesh holds the product and prevents the collapse of the plaster.
- Allows you to apply plaster to any surface with complex geometry. The material does not always fit exactly to the shape of the building base. The mesh accurately follows all the curves of the surface, so the material also copies the geometric outlines.
- Reduces material consumption. If the material is applied to a surface with unevenness and a large number of defects, then a large amount of the product will be required. In the event that the building base is pre-reinforced, then the consumption decreases. The cost of finishing, accordingly, also becomes less.
- Allows you to process any building base. Thanks to the mesh, the plaster holds even on porous surfaces – polystyrene foam and other similar materials.
- Holds a large layer of plaster. A layer up to five centimeters thick is applied to the mesh.
Types of product
There are various types of galvanized plaster mesh available.
- Material that is made by hot galvanizing. The essence of the procedure is immersing the product in hot zinc. Thanks to this, the product fills the smallest pores of the metal. The thickness of zinc is from 10 microns. The cost of such a product is higher than the price of a similar product, but the quality of the mesh is higher. A distinctive feature is the presence of zinc influx on the wire.
- Galvanized plaster mesh, which is made by electro-galvanic galvanizing. The essence of the procedure is that the metal wire is subjected to electrolytic action due to different poles. Zinc thickness – 3 microns. Externally, the product looks more attractive than the previous mesh. The surface is smooth, shiny. Such material is cheaper than hot-dip galvanized mesh, but the product is susceptible to corrosion due to the abrasion of the protective layer, which leads to rust appearing on the finish within two years after repair.
Product dimensions
Galvanized plaster mesh dimensions:
- 1×1 cm;
- 2×2 cm;
- 3.2×3.2 cm;
- 4×4 cm;
- 5×5 cm;
- 10×10 cm;
- 15×15 cm.
How to choose correctly?
The wire joining seams should be taken into consideration when selecting a galvanized plaster mesh. This area’s presence of dark patches suggests that the product has been examined after galvanizing. After plastering, the material corrodes due to the abrasion of the zinc layer caused by this type of mesh production. Rust then becomes visible through the finish coat, necessitating refinishing. It is therefore not advised to select such a product. The mesh made of galvanized plaster ought to be spotless and smooth. This ensures that the finish will last a long time.
Mesh Type | Use |
Fiberglass Mesh | Great for reinforcing plaster and preventing cracks. |
Plastic Mesh | Lightweight and easy to work with, ideal for interior walls. |
Metal Mesh | Best for heavy-duty applications, especially on exterior walls. |
An essential component in guaranteeing the longevity and caliber of wall finishes is the plasterer’s mesh. It offers crucial support, averting the eventual emergence of uneven surfaces and cracks. You can build a more sturdy and stable wall structure by including this mesh into your plastering procedure.
Not only does using a mesh prolong the life of your walls, it also facilitates and expedites the plastering process. It assists in spreading the plaster uniformly, lowering the possibility of flaws. Adding a mesh is a wise investment for anyone hoping to attain professional results.
To sum up, the importance of the plasterer’s mesh cannot be emphasized enough. This modest upgrade ensures that your walls stay sturdy, seamless, and free of cracks for many years to come.
