Construction work can be varied. There are actions that are applied constantly - this is plastering the walls. To achieve a high-quality result, additional components are used. Plaster mesh is an opportunity to make the applied layer durable, which means that this finish will last longer.
Due to this, the product is often used in construction finishing. Before buying, everyone should be aware of how this building material is used and which is better. Reinforcing mesh is used to create reliable surfaces, as well as in pouring the foundation and strengthening floors. Thus, it is applied in many directions. You can’t do without it.
Kinds
Not so long ago, a wooden shingle was the leader in the help of surface plastering. But time is changing, and today there are enough offers on the building materials market. This is a stucco mesh used in decoration. It is made of different materials, each has its own operational characteristics, which builds the choice.
The grid for plastering plastic has another name - masonry. The composition contains polymers, but with high strength. The assortment of mesh is large - with a variety of cells and thickness. Such products are used in all areas of construction. What are the pros and cons of such a grid? Consider below.
pros
Plastic is used in many areas of construction. It is durable and yet inexpensive. The following advantages are worth noting:
- The product does not react to moisture.
- Finishing quality is improved due to the fact that the mesh is not affected by corrosion and decay. It is used in interior and exterior decoration.
- Withstands different temperature conditions depending on the time of year.
- There are no toxins in the material.
- The mesh is resistant to mechanical stress.
- Bolts are used for fastening, self-tapping screws or the product simply goes deep into the solution.
- Low cost in relation to others.
These positive aspects make the plaster grid from plastic the leader of sales.
Minuses
Besides the pros, there are minor flaws:
- The plaster layer should not exceed eight millimeters, otherwise the whole structure loses its reliability.
- Some plastic does not tolerate the alkaline effects of the solution.
- Not everyone considers this reinforcement reliable.
But in what direction is this design used? Wall plastering is one area of application. To align the walls on the street or inside the building, this kind of mesh is suitable. What types are on sale? Plastic tape is found in the interior decoration of drywall joints. Serves to increase adhesion in the process of wall insulation with foam boards. Without a mesh, the quality of work will be poor.
It will not be possible to cope with the plaster coating of a wall with a polystyrene foam insulation without using a reinforcing component. After a certain time, the entire layer will fall off. In such works, a mesh with high rigidity and large thickness is used. The application of sand-cement compositions will occur reliably and efficiently.
The range of applications of such finishes is large. Often it is found in the process of laying the foundation on unstable soils, is fixed between the layers. Mostly considered to be cells with a size of five by five millimeters. Rarely, larger products are used on the outside.
Fiberglass mesh
This option is no less good than plastic material. The main advantage is resistance to chemical attack. High strength allows you to withstand severe mechanical and physical effects. Basically, the work uses a plaster fiberglass mesh 5x5 millimeters. But what are the differences and benefits?
Dimensions, Density
It is already clear that the characteristics of such a material is better than any other. The choice is built depending on the density of the surface, reliability is decided by this indicator. Masters say that this value is in grams per square meter. And when the result is large, then the strength increases. There are three types on sale:
- Applied in interior decoration. Density is 50 by 160 grams per square meter. Two types are on sale - painting and stucco mesh. The first is more simplified and with small cells. Fiberglass stucco mesh is used with a cell of 5 x 5 millimeters or more. It has a high density.
- For the facade. Plaster mesh has a density of up to 160 by 220 grams per square meter. For external work, the size of its cell reaches ten millimeters.
- Finishing the underground parts of the building. This species has a maximum density of up to 300 grams per square meter. Such nets can withstand severe loads and extreme conditions. The cost of the grid is high, because a lot of material will be required for the manufacture.
Marking
By this indicator on the package it becomes clear what stiffness and where the product is used. There are such designations:
- C is the grid.
- SS - fiberglass mesh.
- N - for outdoor use.
- B - interior decoration.
- W - putty mesh.
- A - anti-vandal, high strength.
- Y - gain.
In addition, the package contains other useful information. This is the maximum tensile strength. In the manufacturing process for each mesh, its additional components are used. They allow you to increase the reliability of the product. Often such material is sold in meter, which is convenient for finishing work. With a shortage, it is easy to purchase the required quantity.
The use of fiberglass mesh is:
- Reliability of the decoration layer.
- The ability to increase the adhesion level of the finishing material with the surface of the structure.
- Significant facilitation of complex work.
note
It should be understood that on each surface the stucco will hold in different ways, regardless of whether the grid is present or not. When buying, pay attention to the manufacturer. Doubtful material will not be reliable and perform its functions. Only certified products will become a reliable assistant in construction.
Metal
Plaster metal mesh - a common option in construction. After all, it helps to strengthen not only the finish, but also the supporting structures themselves. Mostly found in exterior decoration. Helps to create a solid structure, effective in decorating. You can work with it on reinforced concrete, brick and aerated concrete structures.
Subspecies
In construction, a mesh of any thickness and with any cell size is used. To plaster the surface, use the following metal additions:
- Fabric metal mesh. Such a specific name is due to the fact that weaving is similar to fabric. Coating - plain and twill, with various cells. In production, wire or galvanized steel is used. Various cell sizes and diameters are available for sale. Depending on the work performed, choose the best.
- Rabitz. A popular variety and in demand in the construction market. Stucco mesh got this name from the manufacturer. It is created from high-quality steel wire, with an additional polymer coating. It is considered durable because it is not susceptible to corrosion. But it is used for fencing and has a color palette. They make it by twisting the metal components by joining. She is able to hold a large amount of plaster. When choosing, pay attention to the diameter of the wire and the size of the cells.
- Welded wire mesh. The wire is laid and connected by a weld. To create a wire or reinforcement is used. The diameter and size of the cell are different. Such a grid is relevant in the process of reinforcing the foundation, laying heat-insulating material. It happens with a polymer coating. They also produce welded non-galvanized plaster mesh. It is sold by footage. The product is used in decoration not only with cement-sand compositions, but also on wooden surfaces, like shingles. There are no application restrictions.
- Masonry net. It is used to connect welds. The diameter is large, which changes the main characteristics and scope. It is suitable for plastering walls, although it is quite realistic to use it when erecting walls and strengthening floor screed. It is realized by footage. The choice is made according to the size of the cells and the diameter of the wire used.
- Metal plaster mesh. By the name it is clear in which repair work it is used. It is created from galvanized heat-treated wire. Such a grid allows you to evenly distribute the plaster mixture. After such work, the wall becomes smooth and such a coating lasts quite a long time.
When choosing, you should pay attention to a lot. The first is cost. It has a big run, so you should pay attention to:
- Used metal for manufacturing. If the manufacturer chooses strong steel, then the costs increase, respectively, the selling price rises. It is better to clarify the grade of alloy.
- Processing quality. This is the presence of galvanization or its absence. When a large enterprise is engaged in production, its costs are less, since the production is large.
- Connection method. It will be better to use welding than ordinary twisting.
Having the necessary information, each of the proposed assortment will find a suitable grid for construction work.
