How to install concrete floor reinforcement mesh correctly? Installation by your own and tips for choosing + Video

In order to install the decorative floor covering, it is necessary to provide a flat and smooth surface.

Therefore, it is necessary to make a screed, thanks to which the mechanical load on the floor is distributed and its strength increases.

In order not to damage the screed and increase its service life, it is necessary to use a reinforcing mesh. We will talk about this type of building materials in this article.

Reinforcement targets

Reinforcing mesh is quite often in demand, since when applied, structures acquire durability and reliability.

The versatility of the mesh allows it to be used to reinforce ceilings, floors, walls and other suitable surfaces. Let's analyze the characteristics of the reinforcing mesh in detail.

Reinforcing mesh is used in two cases:

1. To increase the strength of concrete structures;
2. In order for poorly interacting materials to bond with each other ...

Reinforcing mesh is used for such works as:

1. Floor screed
   For floor screed reinforcement mandatory, since it allows the surface to be durable and maintain integrity. Reinforced mesh is used for screed floors that are insulated with foam, in the absence of a reinforced mesh, the structure will simply collapse.
2. Plaster on a concrete floor
   In this case, a reinforcing mesh is used for better adhesion of the plaster to the base. This material is used when the plaster is applied in a thick layer and for surface finishing. For such manipulations, a metal or plastic mesh is used.

3. Concrete placement
   In this case, the concrete reinforcement mesh acts as an improvement in the strength of the pavement and for even distribution of the mechanical load over the asphalt surface.
4. Overlay application
   Reinforcement mesh allows to reduce point loads on the base.

It is suitable for working with large surfaces when pouring concrete. Also allows you to retain the concrete solution and removes water outside.

What you need to know about the reinforcing mesh

Types

There are two types of reinforcing mesh:

1. Metal mesh;
2. Fiberglass mesh;

Metal mesh

This material has cells, and they can be of different sizes and sections.

For work with plaster, use a grid with cells of 30 mm, the cross section of which is 1.5 mm.

Due to various types of reinforcing mesh, it is allowed to choose its type, due to the load on the finished surface.

Fiberglass mesh

The fiberglass reinforcing mesh is very strong, not afraid of drops temperatures.

No special skills are required to use mesh reinforcement.

The mesh is laid in several stages. First of all, a layer of plaster is applied to the surface, and then a mesh is laid on it. Then another layer of plaster is applied to the dried surface.

Such a reinforcing mesh is used for surface treatment with plaster. Mesh helps improve the interaction of materials. Very often, fiberglass mesh is used for facade finishing. Such mesh has a lower price than metal mesh.

Mesh characteristics

The quality of the reinforcing mesh is determined by positive and negative characteristics.

The advantages of such a mesh are as follows :

1. Resistance to various loads;
2. Fire resistance;
3. Affordable price;
4. The mesh is applicable on any surface;
5. Reduces time spent on construction and increases productivity.

The disadvantages of the reinforcing mesh are quite small .

Reinforcing mesh is a fairly practical material for finishing concrete surfaces. To achieve a good result, you must follow some rules.

Screed laying rules

First, you need to accurately calculate the amount of material.

The screed is made in three stages:

1. The surface is treated and equipped with waterproofing;
2. Reinforcement is laid;
3. Concrete is poured ...

Preparatory work

It is also necessary to insulate the surface well. Next, the surface is treated with a primer solution so that mold does not form on the surface.

Find the highest point of the surface for the reinforcement and set the guide beacons.

The distance between the beacons should be about 1.5 meters, after which you can carry out a rough pouring of concrete. After two days, you can start laying the mesh, before starting work, it is cleaned of various contaminants and divided into pieces.

Placement of reinforcement

To reduce sound and vibration vibrations, a damper tape is applied to the surface.

They also install a special frame, which will serve as stiffeners. All this is fixed with wire. It is better not to do welding work. If the surface is insulated, then the fastening is not done so as not to tear the film.

The material must be overlapped, regardless of its type.

If the calculations of the mesh sizes are not correct, then the mesh must be applied with a second layer. The mesh is laid in small sections. The reinforcing mesh should not show through or show through the concrete.

Concrete pouring

After preparatory work, concrete is poured. A not too thick solution is mixed, then the solution is poured between two beacons and leveled.

To avoid damage and cracks in the screed, it is necessary to wet the concrete surface with water for three or five days. The concrete floor can be fully used within a month.

The choice of this material should be conscious and responsible. You also need to follow all the recommendations and the results will only delight you. We wish you good luck!
