Serpyanka for drywall: characteristics and purpose

Installation of drywall construction requires certain knowledge and skills. As soon as you cope with this task, there will be another question - how to smoothly and imperceptibly close up the GCR joints? After all, this is what will ultimately affect the appearance and stability of the structure. If such work is done with errors, then in the future there will be many unpleasant moments. A mesh made of cracks is capable of greatly spoiling the appearance of the topcoat, which can force rework repairs. In order to avoid negative consequences, it is necessary to use proven and high-quality materials, as well as to strictly observe the technology of work.

The construction reinforcing mesh, called serpyanka, gained wide popularity.Visually, it has a distant resemblance to a medical bandage. This is a large network based on fiberglass or synthetic material. On one of its sides applied adhesive composition.

Serpyanka is an indispensable tool for sealing plasterboard joints, copes with the processing of corners and irregularities and can be used in many types of construction and finishing works. Serpyanka is used to smooth the joints between the ceiling, floor and walls, before sticking wallpaper and painting, as well as to form a flat surface on gypsum constructions. The grid is wound into rolls 50 millimeters wide.

In the presence of possible contamination on the treated surface there is a risk of tape detachment. Therefore, it is necessary to ensure the purity of the desired area. Serpyanka should be used that width, which is necessary depending on the size of the seam. The coating should be smooth, without protruding fasteners. The presence of defects in drywall is unacceptable. All sheets must be securely fastened in the design.

With increased humidity, the gypsum plasterboard can be deformed, therefore a favorable microclimate at the place of work is very important.Low temperatures, like too high temperatures, can have a negative effect on them. Indoors should be on average about 10-15 degrees Celsius. The possibility of drafts also need to be excluded.

Using serpyanka, you can avoid swelling and irregularities on the surface. However, you need to take into account some features. The tape is applied only on the puttied surface; it does not make sense to glue it onto clean drywall. Serpyanka is ideal for gluing seams, well smoothes cracks, it is convenient to strengthen panels for walls and ceilings. The use of serpyanka protects the puttied surface from adverse external effects and the appearance of cracks, and also fixes its connection with the drywall. The tape can have a length of from 20 to 150 meters. It is produced in the size range from 42 to 230 millimeters. Serpyanka density - 50 g / m2.

Serpyanka is waterproof and very reliable, is well fixed at the right place and is not subject to corrosion. Due to these qualities, the material can be used for both internal and external works.

The grid is available in two versions:

• When working indoors, a tape with cells of small diameter is used - 1-3 millimeters.Basically it is used for fixing seams in drywall and other structures.
• With external works, the diameter of the tape cells is already larger - from 5 millimeters, and the mesh is wider. The tape may not have an adhesive side. It is made of glass fiber and polyester. Mounted on a special glue without water base. Used in joints of window and door frames. The range of works with this species is not particularly wide. Tapes from lavsan are very thin, so the use of putty with them is optional.

In any building material has its advantages and disadvantages, and serpyanka is no exception. One of the main advantages is the affordable price range and ease of use. With its help, the docking seam of drywall sheets is enhanced. The material tolerates aggressive environments, is resistant to vibrations and provides reliable adhesion of materials. The problem may be the choice of a special solution of putty and insufficient tape strength.

Before starting work, you need to remember the necessary temperature regime, which should not change for at least two days.A prerequisite is the elimination of drafts. The room must be dried, for this you can use a special device. If the drywall is wet, the seams can be deformed, which will significantly complicate further work.

Drywall sheets must be securely fastened in the constructionAll screws - stand correctly. Before you begin to close the seams, you need to prepare the surface. It can be cleaned either with the help of detergents, or simply wipe with a sponge. Primarily, a primer is applied to the drywall. This is necessary for bonding putty and material. The soil must be laid in a dense layer. Acrylic, acid and alkyd and their varieties can be used.

The most expensive is acidic primer. The price is explained by high operational properties: it absorbs excess moisture and has a dense texture. Acrylic primer is very thick and adheres well to the treated surfaces. Most often complete with it is a hardener. The thinnest is alkyd primer. It has the greatest expense in work and is used as an intermediate.

After priming the surface is puttied.In order that at the end of the work there are no defects, the putty must be of medium consistency and must be uniform. Serpyanka applied to the wet layer. It is necessary to fully press it into the surface. After that, a thin layer put the finish putty. The surface must be dried.

Serpyanka with a sticky layer has several advantages. The roll is easy to unwind and does not create additional problems in use. The tape is similar to a bandage, so the putty easily penetrates through the cells and completely fills the treated seams. It is putty in the future and holds the main structure, and serpyanka, in fact, provides the strength of adhesion.

Not all adhesives can be used in the work. Those that contain water - are strictly contraindicated for paper tape or tape from Dacron. The fact is that water can come into contact with the main framework of the structure, which is made of metal.In this case, rust stains may appear through the putty and its appearance will be damaged. Serpyanka consumption per 1 square. m is calculated individually.

When buying serpyanka should ask the manufacturer. Basically it is made by domestic firms, and among them there are reliable and well-established suppliers. We must not forget that cheap products may not be too good, and this will necessarily affect the quality of the finish. If the mesh is stratified, this indicates poor quality or defective products. It is useful to check the adhesive layer.

In spite of the fact that it is quite simple to use serpyanka, it is necessary to know the basic rules for working with it. In order to protect the adhesive layer from drying out, it is useful to place the tape in the packaging after work. The surface must also be protected from dust. If air gets into the tape between it and the putty, then cracks may appear on the surface over time. In addition, you need to carefully monitor that when cutting the tape from either side did not start to get out the thread. They can damage the finished layer.The part that began to bloom, it is better to just cut straight.

The correct calculation of the required amount of material is also important. He can save your time and money. Material consumption depends on various factors of construction, types of work and is calculated individually. Serpyanka tape is used in most of the construction works; therefore, it is available and available in every specialized shop. When buying, you need to check the quality of the goods, as it does not always correspond to the assurances of the manufacturer.

When installing constructions of drywall, the use of serpyanka is irreplaceable. It reduces the stress on the frame itself, prevents cracking, helps to fix the outer corners in the structures. If you do not use the grid when sealing joining seams, then over time they are deformed or destroyed. It is important to properly putty and observe the basic conditions when working with these materials. If there are gaps in the GCR construction, it will lose its reliability and functionality. Therefore, it is necessary to carry out all manipulations correctly, carefully and in accordance with the technology.The result is not long in coming, and the finished work will delight you for a long time.
