Plaster mesh plastic: features of the material

The right materials are essential to guaranteeing a sturdy and long-lasting finish for your walls. Plastic plaster mesh has become more and more popular in recent times. This multipurpose product is essential for strengthening plaster applications and enhancing the overall durability of wall finishes.

Comparing plastic plaster mesh to conventional materials, there are a number of benefits. Because of its light weight, handling and installation are made simpler. It also keeps out moisture, which lowers the possibility of mildew and mold developing. Making an informed decision for your upcoming wall finishing project can be facilitated by being aware of the features and advantages of plastic plaster mesh.

This post will discuss the benefits of plastic plaster mesh, its advantages over alternative materials, and practical application advice. Gaining knowledge about this material can improve the caliber and durability of your wall finishes, regardless of your level of experience with DIY projects.

Plaster surfaces can be strengthened with plastic plaster mesh, which is a lightweight, flexible, and easy-to-work-with alternative. Because it won’t rust or corrode like metal mesh does, it’s a durable option for a variety of wall finishing projects. Because of its adaptability and simplicity of installation, both professionals and do-it-yourselfers choose it.

What is the mesh for

Customers who have had repairs done by builders often ask this question, and with good reason—before there was any mesh visible, the walls were plastered, and the fix managed to hold.

However, recall the number of years that elapsed before minor fissures or even fragments of plaster fell off the walls? Ten, five? Usually, the first indications of deterioration on unreinforced plaster don’t show up for two to three years.

Many people tend to blame employees or subpar cement for this, but in reality, the cause is simply that most plaster mixes shrink after they completely dry, which causes microscopic movements in the walls and, ultimately, crumbling walls that require new repairs.

To mitigate the situation and prolong the plaster’s lifespan, constructors devised two techniques:

  1. Make a lathing on the wall from small boards. The technology was called – plaster on lath.

  1. Leave notches on the wall with an axe.

Although the first method appears more efficient, it isn’t because wood expands when it absorbs moisture and then contracts again when it dries. Plastering over shingles, therefore, not only does not prolong the coating’s service life, but it frequently shortens it as well.

Regarding the notches in the wall, this technique is intended to make the mixture stick to the wall better because of the uneven surface. It is effective, albeit it only preserves the plaster layer’s integrity for a very brief period of time. Both of these techniques are no longer used because plastic plaster mesh has entered the building industry, drastically altering public perception of wall plastering.

In this instance, the plaster mixture is held together and kept from crumbling and cracking by the plastic plaster mesh, which serves as reinforcement. Since the coating is entirely monolithic, no additional reinforcement is required. Plastic plaster mesh walls last a lot longer, even when it comes to facades that are subjected to daily exposure to a variety of elements, such as mechanical loads and natural influences.

Advantages of plastic mesh

  • Plastic mesh for plaster differs from metal analogs in its light weight, which does not create additional load on the walls, which means that it can be used not only on capital walls, but also on light partitions.
  • Relatively low price, for example, a 5×5 plastic plaster mesh costs only 15 rubles per square meter.
  • Due to the fact that the mesh is sold in rolls of about 10 meters, a large amount of area can be covered at a time, this is especially important if the repair is done by hand and without assistants.
  • Unlike metal, plastic plaster mesh does not rot, and therefore does not give corrosion spots that could appear on the surface.
  • High-density mesh can withstand up to 5 centimeters of plaster layer.

Crucial! The mesh can be recessed into the initial layer or fixed directly to the wall using dowels or anchors, depending on the plaster’s thickness.

Naturally, there are drawbacks to this material as well, so you may want to consider other options if you don’t want to redo the repair every few years.

Flaws

  • Despite the fact that plastic is resistant to most types of solvents used in the repair, it is very afraid of alkali, which is contained in large quantities in cement.
  • In comparison with metal or fiberglass (cm. Fiberglass plaster mesh – types and scope) competitors, plastic plastic plastic plastic grid has the lowest rupture resistance, therefore, if it is supposed to make a plaster layer more than 5 cm, then it is better not to use this material.
  • Any plastic has small thermal extensions and deformations that can affect the quality of the coating.

As you can see, there are drawbacks as well—some of which are fairly serious. For this reason, you should thoroughly examine all the subtleties of the wall where the plastic mesh will be utilized before selecting it.

Types of plastic mesh

Plastic seems plastic, so how can it be any different? However, contemporary producers of reinforcing mesh make an effort to meet the needs of every customer, regardless of the goals they establish. For this reason, plastic plaster mesh comes in a variety of colors—which is generally not a big deal if the mesh is covered up by plaster—as well as densities.

This indicator establishes the maximum load that the plaster layer is capable of supporting. The maximum thickness of the plaster layer is also indicated by the mesh density parameter.

Three primary models of plastic mesh are the most widely used; the density variety is very wide, and theoretically you can choose a mesh with an accuracy of up to a centimeter of the plaster layer; however, generally speaking, all such calculations are approximate, and the maximum is taken as the main value.

  1. Density 70 kg per cm2, withstands a plaster layer up to 30 mm inclusive.
  2. 145 kg per cm, with a load from 3 to 5 cm.
  3. 165 kg per cm, with a plaster layer thickness of more than 5 cm.

Counseling! When choosing a mesh, you should always consider the reserve, which should be between 20 and 30 percent, in addition to the calculation error. This is carried out in the event of unanticipated circumstances and potential wall discrepancies.

Yet plastic meshes can be distinguished by more than just color and density. The configuration of the cells is another parameter. Initially, it might appear that neither this parameter nor the color make sense. After all, the mesh will still be covered in a thick layer of plaster, so what difference does it make in terms of appearance?

The answer is actually quite straightforward: wall reinforcement is just one of this mesh’s widely used applications. Its use as temporary fencing at construction sites and even as a permanent fence in summer cottages has increased recently, and this is where the aesthetic aspect becomes crucial.

The plastic mesh is labeled with Latin acronyms based on the variations in cell shapes:

  • SQ – mesh with square cells.
  • PCF – diamond shape.

For plastering, the option with the diamond cells is thought to be better because it is a mesh that is simpler to secure with anchors. The mesh remains in its designated location, and the fastener cap is fixed in the diamond’s upper corner. When there is no helper available to support the mesh during installation, this is extremely crucial.

Feature Description
Material Plastic mesh
Durability Resistant to moisture and corrosion
Flexibility Can be easily cut and shaped
Installation Simple to attach to walls with adhesives or staples
Use Helps improve plaster adherence and prevents cracking

For wall reinforcement, plastic plaster mesh provides a dependable and adaptable solution. Its corrosion resistance guarantees long-lasting performance, and its lightweight design makes it easy to handle.

Plastic plaster mesh is easier to cut and install, and it is more moisture resistant than metal mesh, even though it might not offer the same strength. This can be a big benefit for a variety of building and remodeling projects.

All things considered, plastic plaster mesh is a useful option for a variety of uses, offering a compromise between robustness and usability. To obtain a strong and durable finish, it’s something to think about for your upcoming project.
