Fiberglass mesh: advantages and disadvantages

Rondy Product Page

Glass fiber mesh is an important element in modern technology. The material is used when it is necessary to strengthen the finish of the wet type, hydraulic insulation, ceilings, floors. Also, using it, restore different surfaces with elements in the structures.

Application

Fiberglass nets are used when it is necessary to carry out work in construction. At first they were rods with wooden slats, which were stuffed onto the surface of the wall. Then they were replaced by metal mesh. Now they are replaced by products from glass fiber and plastic.

But these elements are meant to reinforce the finishing layer, to create a framework inside that will hold the lining,made as a monolithic block over the entire surface. Fabric prevents cracking, shedding, flaking, destruction.

The increase in adhesion of the material for decoration with the surface is due to the fact that its area increases with endless relief protrusions in the mesh elements. A layer of plaster with putty will not hold tight on every material. Therefore, when working with foam, silicate brick and similar materials, they will certainly use reinforcement.

Reinforcing mesh is used when you need to handle joints, seams with connections. The mesh is relevant when working with materials that look like sheets. This is gypsum cardboard, polystyrene foam, various panels with blocks.

Fiberglass mesh is used when necessary:

• installation of hydraulic insulation and heat insulation coatings;
• when it is necessary to reinforce the place with abutments in the windows and blocks of doors to the surface of the walls;
• to reinforce bulk floors with couplers.

The need for strengthening and reinforcing coatings with a wet application is dictated by ordinary physics. Applying a thin layer to a surface with a large area will cause uneven shrinkage during drying. Therefore, it can crack when aging takes place.

Further finishing is subject to temperature changes and moisture. This contributes to the appearance of temperature expansions in the materials. In different parts of the surface, the processes are different. As a result, an uneven change in size occurs. Cracking of the plaster occurs.

Destruction can be observed because the recipe is not complied with when the mixture was prepared. The presence of such a moment is considered normal when it is prepared on its own. There are deviations from the required parameters in the layer thickness, the technology is violated when laying the coating.

Often this can be observed on facades with external elements in structures. Here changes in temperature with humidity are especially significant. When working on the facades from the outside, they use stronger, reliable grids.

Another important difficulty when finishing wet looks, is the presence of incomplete adhesion to the surface area. When the material has a smooth texture density, then water is poorly absorbed, pores with irregularities are absent on the surface. The coating on it is held not for very long.

Fiberglass mesh, on the contrary, perfectly glued.It will be held on the surface of almost any material. So, it will become a link mediator, which has the same grip with the wall surface and material for decoration.

Purpose of use

Reinforcing mesh can be used as a skeleton during the filling of spaces with voids between sheets and blocks in materials for construction. If such a gap has a large width, putty inside it will not hold. She quickly showered. The seam will open. With the help of the grid, the plaster is held after it has been destroyed or cracked.

What the fiberglass mesh consists of can be understood from its name. Using aluminoborosilicate glass, first thin threads are drawn. They can be bent easily. However, they will not break. They also have high strength. Then from them the formation of beams occurs, which are woven like a grid, having cells with different sizes. The most common cell sizes are two by two, five by five and ten by ten millimeters.

The surface of the material is specially treated to increase its alkali resistance. To make such protection, the fibers are impregnated with a polyacryl dispersion composition.It allows the grid to be inside an alkaline environment without difficulty for a very long time.

Polyacrylic impregnation is imperative. When it is not, it is impossible to use such material using plaster or putty. After some period of time it will dissolve under the action of alkali.

Grid plaster of glass fiber, having a special composition with treatment, characterized by the presence of unique performance properties.

Advantages and disadvantages

Advantages of the reinforcing mesh:

• It is resistant to aggressive environments. It can be perfectly combined with the compositions of mineral plasters, in which there is an alkaline medium.
• Maintains a large degree of stress.
• Able to provide surfaces with resistance to shocks, increases their characteristics related to strength.
• Perfectly capable of adhering to the surface of putty and plaster.
• Protects the coating from cracking.

Negative characteristics:

The disadvantage of the grids is that at the level of its surface it is not necessary to carry out the application of a solution having a thickness greater than six or eight millimeters.Reinforcement in this embodiment will not benefit. The second disadvantage was the moment that any plastic is resistant to the aggressive effects of the chemical environment of construction solutions. Under the action of alkalis, the reinforcement mesh is dissolved.

Any property is directly dependent on which grid has a density. This parameter is determined using the ratio of the mass of the material in grams to the square meter of its area. The degree of grid stability to different external influences will be higher than the density.

You may notice the material is universal. It provides an opportunity to improve the quality of the quality of any process for finishing, starting with a rough alignment, completing the work done by the painters. It is not very expensive. The effect of use must be given due attention.

How to choose?

Making the choice of the grid, you should pay more attention to the observance of the geometric dimensions in the canvases and cells. You need to see if there are no stretched or bubbling areas. When places with warps are found on a roll during unfolding, it will not be possible to perform a high-quality packing of the material to the surface level.

Reinforcing mesh have a density of one hundred and sixty to two hundred twenty grams per square meter. They are used when you need to perform work related to putty and plaster.

Also, nets are used in the basement and underground parts of buildings. The material that is included in this group has a density of from two hundred and twenty to three hundred and thirty grams per square meter. This view is called mesh reinforcement. They can withstand a significant load with extreme conditions. These materials are more expensive. To produce them, you must have raw materials in larger quantities.

Metal grid

They use metal netting to reinforce the plaster layer in the finish, the walls themselves, when they have a surface that is not quite strong. The material is popular. It is in demand when reinforcing a layer of plaster in the walls from the outside.

The mesh is used not only as a reinforcing primary layer in the finish. This is a decorative finish from the outside in the plinths and other structures made of reinforced concrete or brick. For different surfaces, regardless of what the requirements in relation to the thickness and strength in the applied layer.Grids are used with cells that have different dimensions. The material used in the manufacture of nets, there is a relief with different heights, different thickness.

Applying chain-link mesh

Now the workbench is manufactured using carbon-doped high-alloyed steel wire. She comes with a polymer coating. The chain-link, which has been coated with polyvinyl chloride, is longer in use. It does not corrode. Able to withstand actions from external moans. However, this grid is often used to create fences, and produced in a different range of colors.

The chain-link is made by interlacing wire.which has a diameter of one to three millimeters in a spiral. Then they are crossed with each other, forming a common mesh sheet. Such a grid of metal is suitable for covering walls, during the construction of which adobe or clay was used, before putting solutions on their surface. Using the mesh, a reinforcing relief layer is created. He holds a large volume plaster. The thicker it turns out, the larger the cells will be. Attach the grid in the same way.

Taking into account the availability of the scope of use of reinforcing nets, the enterprises producing it offered a huge variety of this material assortment in construction. Understanding the main criteria when choosing, you can easily make the purchase of roll material of excellent quality, which is suitable for work.

Fibreglass Mesh is an essential component of our render systems. It helps provide strength and flexibility to our thin coat render systems ensuring that the render doesn&#;t crack in the years to come. 

The fibreglass Mesh is made of neatly woven fibreglass thread. This type of mesh is widely used in plastering and rendering for wall reinforcement, external wall insulation and roof waterproofing. We offer different weights of mesh depending on the intended use. Typically, heavier mesh provides more impact resistance within the render system. At EWI Store the heaviest mesh we sell is our Orange Fibreglass Mesh at 165g/m2 . As a result of the weight, this is often used in areas that are likely to endure heavy impacts e.g. a wall where a football is kicked against it.

All of the mesh we sell is alkali-resistant, and this helps prevent it being broken down by the chemicals in the other mortars and adhesive materials. Fibreglass Mesh is also used to create reinforced stress patches around windows. Small squares are cut out and embedded in the basecoat to protect the edges of reveals. Corners in construction are inherently weaker, therefore Fibreglass Mesh can secure these areas. In combination with beading, these features can greatly enhance the strength of the system. Fiberglass mesh is also used in construction for its fire-resistant properties. When used in conjunction with fire-resistant materials, it can help prevent the spread of fire.

Where do you put the fibreglass mesh in render systems?

Within both render systems and external wall insulation systems, the fibreglass mesh is embedded within the basecoat layer. The mesh needs to be embedded within the basecoat while it is still wet. We always recommend getting the mesh embedded within the middle of the layer of the basecoat, rather than too close to the surface or sitting right next to the wall.

In thin coat render systems, the basecoat thickness is normally between 4-8mm, so installers tend to have different embedding techniques.

A notched trowel can be used to apply the basecoat to the wall at the required thickness. Following this, the mesh can be tapped into the basecoat. A straight edge trowel can then be used to &#;pull&#; the adhesive through the mesh by applying pressure to the basecoat.

Other installers will apply a thinner, first pass of adhesive, then tap the mesh in mesh in place and then apply a second layer of the basecoat. Either method is absolutely fine. However if you do go with the second method, ensure the first pass of basecoat has not dried before applying the second pass of mesh &#; the mesh needs to be embedded within fully wet product.

Overlapping mesh in basecoat

During weather and temperature changes, the external walls of your home expand and contract minutely due to the heating and cooling processes. Mesh is used to help the system &#;flex&#; with these building movements to help prevent cracking. 

All of our mesh comes with markings 100mm from each end. This marking illustrates the overlap of the mesh required when installing it. Each strip of mesh needs to overlap the last by 100mm otherwise cracks can appear in this area over time.

The mesh provides additional strength to all thin coat render systems. The additional strength also helps prevent cracking so we would always recommend it.
