Plaster or drywall - which is cheaper and better? Drywall or plaster - which is more profitable, faster, easier? Alignment of walls with gypsum boards or plaster.

Building a new home or just renovating an old one leads the owner to think about choosing a finish. For many years, the walls were leveled with plaster, but now the situation has changed radically. The construction industry does not stand still, so manufacturers decided to make it easier by releasing drywall for sale. This is a worthy competitor to plaster, but both types of finishes have both significant advantages and disadvantages. It is for this reason that many people sometimes think for a long time about the question: drywall or plaster - which is better? We cannot give you a definitive answer, as both options are good in their own way. To choose one or another finishing method, you should get to know them separately, which we will do today.

Definition of drywall

Which is better - drywall or plaster walls? Let's start the review with drywall, which was invented in late XIX century in the USA. In those days, the material was not widely used, and only after its appearance in the USSR, it was appreciated.

GKL is a building material consisting of cardboard sheets and an inner layer of hardened gypsum composition. It is widely used as ceiling decoration, for exterior and interior decoration walls and for interior partitions. It cannot be used for facade works and in rooms with high humidity.

Important! Manufacturers produce GKL sheets in three standard sizes, 1200 mm wide and 2 to 3 meters long. The thickness of the canvases can be 9.5 mm or 12.5 mm.

Main types drywall sheets:

• Standard drywall sheet, labeled GKL.
• Waterproof GKL with GKLV marking. Its difference is the presence of special antifungal substances in the gypsum layer.
• Fire-resistant GKL with GKLO marking. In fire-resistant boards, the sheet is reinforced not only with clay, but also with reinforcing fiberglass. It is thanks to this structure that the canvases are able to withstand a strong fire for an hour without flaring up and spreading smoke around the room.

Important! The type of drywall can be determined by external staining. So if the sheet has grey colour, then this is an ordinary GKL, the green designation indicates a waterproof material, but the pink one indicates a fire-resistant one.

Drywall instead of plaster - the pros and cons

So we come to the consideration of strengths and weaknesses this finishing material. Let's figure it out together.

Pros:

• Minimum dirt and debris. During the duration of the work, you will not find dirty and wet marks on the floor, since this material has a dry structure and does not require moisture at all.
• Ease of operation and installation. Anyone can level the walls of the GKL without any special building and carpentry skills. It will be easy to independently install drywall on the ceiling surface.
• Possibility of waterproofing. Sheathing with such material allows you to sheathe the walls in order to create a waterproofing system that will save the room from noise from the street.
• The use of flame retardant material will ensure fire protection walls.
• The ability to absorb moisture. Thanks to this property, your walls will be able to “breathe”, so fungus will not form under the finish.
• The possibility of masking communications. Between the GKL sheets and the wall there will be an empty space in which cables and other types of communications can be hidden, and it can also be filled with insulation.
• Good flexibility. Plasterboard canvases bend well, which allows you to design various design designs on walls and ceilings.

Disadvantages:

• Decrease usable area. GKL must be mounted on a special metal crate which will take most room space.
• Performing several finishing works. Wall cladding is just one stage of work, after which it is necessary to putty the joints and apply a fixing finishing material.
• The inability of sheets to withstand heavy loads. A plasterboard wall cannot hold a large and heavy shelf, bulky interior items, so additional elements are placed under the sheets.

Definition of plaster

Plaster began to be used a long time ago, and this is no accident. Thanks to this mixture, it is possible to produce internal and exterior finish walls, including the ceiling. As a result of the work carried out, you will receive a hardened surface surface.

Kinds:

• Normal. Used to level walls and protect them from negative external influences. Unlike drywall, plaster can be applied to both interior and exterior surfaces. external walls from the front side of the room. Ordinary plaster can be of three compositions: gypsum, lime and cement-sand mixture.
• Special. This name refers to the addition of certain components to the mixture, which make the coating heat-saving, soundproof, X-ray protective and waterproofing.
• Decorative. It has an exclusively decorative function. It is applied at the final stage of surface finishing to give the walls or ceiling an attractive look. appearance. Such plaster is produced in different variations: colored, silk, Venetian, stone and other types.

Material difference:

• Lime mortar is a mass consisting of lime and sand, diluted to a ratio of 1:4. Cement can be added for durability. This mixture is environmentally friendly and is used for outdoor work.
• The cement-sand mass, prepared in a ratio of 1: 4, can be applied both to external and internal walls. It is with this solution that large surface defects are removed, the plaster layer will serve without destruction for several decades.
• Gypsum mixture is used for internal works. The resulting coating will have an even and White color, which can be processed by any option: stick wallpaper, paint or lay tiles.

Advantages and disadvantages of plaster

This long-used finishing method is a drywall competitor, which has a number of significant advantages. But still, strengths the use of plaster is hard to miss. Let's take a closer look at everything.

Pros:

• Durability. It is considered the most important advantage of plaster. With proper work, in compliance with the instructions for diluting the mortar and technology, it allows you to forget about the problem of an uneven wall for at least 20 years.
• The ceiling and walls, aligned with the plaster method, will be strong, as reliable as possible, and withstand impacts.
• Ability to support heavy objects. The surface covered with plaster can easily withstand large furniture, appliances and other items.
• When applying the plaster mixture on walls or ceilings, the area of ​​\u200b\u200bthe room will remain the same.
• Possibility of installing single insulation wires on plastered walls.

Minuses:

• Lots of dirt. In any case, the plaster mixture must be diluted with water, so after completion of the work you will have to spend several hours cleaning the premises.
• Long period of time for plastering. After applying the material, you will need to wait for it to completely dry and harden, and after that you can proceed to the finish. All these processes can take from a week to a month of your free time.
• While doing plastering works the customer will not immediately be able to notice flaws on the surface by a specialist, so the work will have to be redone. For such meticulous work, you always need to choose only responsible and experienced craftsmen.

As you can see, it is impossible to level the walls without plaster and drywall. In any case, you need to choose one option that suits you best.

To get the correct geometry of the room, you can use plaster, but with a trowel it is very difficult to make straight lines, much easier leveling the walls with drywall, the pros and cons which we will consider next.

Leveling walls with drywall - the pros and cons are obvious

In any case, even if there are several shortcomings, one thing is obvious - to assemble a frame for wall cladding from special profiles with instructions and necessary tools even a beginner can. AT skillful hands master plaster is applied to any vertical surface or ceiling with a smooth, even layer, turning into a reliable coating for brick, concrete or even wooden walls. However, there are few such craftsmen, and often inexperienced beginners enter the fight with unruly building materials, getting something indescribable as a result. An excellent substitute for wet plaster is its dry and relatively cheap counterpart - drywall (for example, Knauf sheets), multilayer sheets of which have a perfectly flat surface.

Step by step instructions with exclusive photo and video materials.

First of all, let's dwell on the positive aspects of the material in question. Its main purpose is the alignment of the walls, and the effectiveness in solving problems with irregularities is a definite plus of drywall. It is hardly possible to find any substitute that effectively forms the geometry of the premises even with differences in surface levels of up to 8-10 centimeters. The second positive feature is the ability to create vertical and ceiling structures of the most complex shapes which is highly appreciated by designers. And another quality that provided the material with high popularity is the masking of communications. It is easy to stretch any wires and pipes under the skin between the frame profiles.

It would seem that all of the above is already enough to consider drywall the best option for wall decoration, but it would be wrong to ignore its other positive aspects. In particular, such as environmental friendliness (material components - a gypsum layer with reinforcement and a cardboard shell), versatility - the coating is suitable for any type of room. With the exception of the shell, the sheets of the material in question are not combustible, and some grades are completely refractory, this is another plus. Some manufacturers claim good soundproofing qualities of their products, but this is only partly true. Drywall is only to some extent able to dampen noise, which is why various noise absorbing materials are always placed under the skin.

The website site masters have prepared a special calculator for you. You can easily calculate right amount drywall.

But leveling the walls with drywall pros and cons is equally significant. So, a counterweight to fire resistance is high moisture absorption. That is why, starting to extinguish with water small fire in a room finished with drywall, you can say goodbye to the sheathing, even if the fire has not yet damaged it - water will do it. Also, an irreparable disaster will result in the flooding of the apartment by neighbors from above, or simply an increase in humidity in the room. Based on all this, it is not recommended to use this coating in the bathroom and in the kitchen. However, there are brands that are not afraid of water, but they are somewhat more expensive. standard sheets. Two more minuses, less critical, are the relative fragility of the material and a slight reduction in the volume of the room when using load-bearing profiles.

Drywall instead of plaster - what's the difference?

Both of these materials are similar in that they are used to level the walls, but otherwise they are direct opposites of each other. If the lining of gypsum sheets is laid in a matter of hours, then plastering the same area takes more than one day, due to the layering. The first of the materials is extremely light, it weighs approximately a little less than a kilogram for each millimeter of thickness (regular or moisture resistant drywall), which for a 9 mm sheet will correspond to 7.5 kilograms. The second type of coating is quite heavy, the mass of a square of a solidified mixture with a layer thickness of 3.3 centimeters will be approximately 25 kilos.

The thicker the drywall sheet, the less gaps between the profiles must be done in the frame so that the structure does not deform under the weight of the skin.

Also, the difference between the finishing materials of interest to us is the magnitude of the loads they can withstand. If you glue a couple of plates with hooks to the plaster layer applied to the reinforcing mesh and hang a small bookcase on them, nothing will happen to the coating. The same operation carried out with drywall will lead to its deformation. Directly during the finishing work, mixing the mixture and covering the walls with it is always associated with large quantity dirt: splashes, scattered mortar components, excess scraped off by the rule. The use of dry plaster sheets allows you to maintain relative cleanliness, a small amount of gypsum dust is formed only during the sawing of the material.

A number of factors pushing the use of drywall instead of plaster. So, for example, let's remember the simplicity of laying communications under sheet sheathing and look at a wall covered with cement-sand or lime-gypsum mortar. The frozen mixture leaves no other options than to ditch the coating, that is, to cut grooves in it for wiring. Further, the result after mounting the sheets immediately pleases the eye with smooth surfaces. The plaster applied to the walls requires additional attention to itself, in the form of smoothing with a rule, glossing with a grater and careful processing of the shells remaining after finishing work with putty.

What drywall has no equal

Shields made of boards brickwork, welded steel sheets- all this can become a partition in the apartment, but it will not look the best, and it will create little convenience. As for the leveling mixture, it can no longer replace the wall in any way. But drywall sheets for this purpose are used constantly and have proven themselves in the best possible way. The technology is not much different from the standard sheathing of the room, just the supporting profiles are made into a frame not on the surface of the wall, but across the room with fasteners to the floor and ceiling. This is precisely the main advantage of drywall over plaster.

disadvantages sheet material mounted on a frame built for a partition are quite standard. This is the fragility of the sheets, which becomes more noticeable when there is no rigid base - with some effort, you can break through a light wall, and this can only be avoided by reinforcing the frame with additional profiles. This is hydrophobia, which, by the way, may turn out to be positive quality when it is necessary to bend the sheet into any curly design(for this purpose, drywall is moistened and in this state it is attached to the frame). And, finally, low sound absorption, without a special soundproofing filling, a partition sheathed with sheets will turn into a drum, sounds will be transmitted from room to room through metal profiles.

Everyone knows that the pledge quality repair there will be a perfectly smooth and beautiful ceiling surface, because this is the object that catches the eye first of all when entering the room. From good alignment ceiling will affect the whole appearance of the room, since uneven surface will distort the lighting, create the effect of poor-quality repairs, and also make the room uncomfortable. It's no secret that drywall is a material that not only perfectly levels, but also insulates, and also soundproofs the room, but plaster is still relevant and popular. What is it connected with? This will be discussed in this article, where the advantages and disadvantages of each of the finishing materials will be described in detail, as well as in what cases better fit one option or another. So what better plaster or drywall?

What is this article about

What is plaster, and what is it like?

Plaster is a material that is widely used in construction and repair activities to create perfectly smooth and smooth surfaces walls and ceilings, as well as to prepare them for subsequent decorative finishing. It consists of gypsum or cement, lime, as well as various special additional substances that enrich the material, make it resistant to moisture, mold, fungi and other adverse environmental influences.

Types of plaster:

1. Ordinary plaster - this type is designed specifically for finishing interior or external surfaces. It has a democratic price, while not whimsical to use. It is preferred to be used by both professionals and beginners in the repair business. Ordinary plaster is universal and most popular because it has excellent soundproof and drainage properties.
2. Decorative plaster is a newer and more perfect version of the usual one. In addition to standard components, it contains elements such as coloring pigments, nylon fibers, acrylic resins and others, it is very beautiful and practical. At the same time, such plaster is universal and environmentally friendly, creating the right microclimate in the room. It should be noted that the quality decorative material Can last for decades with regular cleaning and maintenance. It does not fade over time and does not collect dust, and in case of fire it does not burn.
3. Aqueous and non-aqueous plaster - the second option is a material that contains polyurethanes and epoxy resins, which are used as finishing components for interior work to make the surface more textured.

Advantages and disadvantages of plaster

The advantages include the following:

• after a quality plastering, the surfaces of walls and ceilings are able to retain their presentable appearance for a long time, they can last 30 years or more without additional repairs;
• the price of the material is very democratic, if someone is wondering what is cheaper than drywall or plaster, then you can easily say that plaster costs about half the price of finishing analogues, while, as for finishing work, they will also cost less, as at least 20% than the installation of GKL, especially if the work is carried out independently;
• plaster allows not only to level the walls well, but also to make them stronger and more reliable, and if you try especially well, they will turn out to be shockproof;
• surface after plastering great for creating additional decor, for example, for the installation of heavy and dimensional elements such as furniture or appliances, drywall, in this case, loses a lot, because he is not able to withstand strong physical exertion, for this he will have to be additionally strengthened, which means spending additional money and time.

With all the advantages, the material has its drawbacks:

• the use of plaster is not complete without “wet” work, while the installation of drywall boards is quite dry, so beginners, wondering what is better plaster or drywall, prefer drywall, being afraid not to cope, as improperly diluted material can ruin the entire surface repair;
• working with plaster takes a lot of time, especially if a beginner takes up the work, and the working surface is of insufficient quality. Drywall, unlike plaster, is less whimsical in installation, therefore, in some cases, experts advise using it, especially if repairs need to be completed as soon as possible short time without special skills and knowledge in the field of installation and repair;
• the unevenness of the walls greatly affects the plaster, since highly rough surfaces will require much more source material, which will greatly increase the cost of the entire repair. Drywall in this case is more advantageous, since the complexity of working with it does not depend on the quality of the surface;
• without professional titles, it will be much more difficult to determine whether any technological aspects of the application of plaster have been violated.

This video describes in detail the process of leveling the walls with plaster:

What is drywall, and how does it happen?

Drywall is a material that is the main analogue of plaster, it is made of gypsum, which is finished on both sides with cardboard. With it, you can finish both the walls and the ceiling, they become perfectly even and smooth, prepared for further decorative finishing.

Ordinary drywall is well suited for rooms with a normal level of humidity, without strong temperature changes. But, if the humidity in the room is high, for example, in the bathroom, kitchen or bath, then this is not a reason to refuse drywall finishing, because now there is a moisture-resistant analogue of ordinary drywall sheets. It will look very beautiful and noble, while it will not deteriorate from exposure to moisture, and will not be covered with mold and fungi, which will allow it to last for a long time.

Advantages and disadvantages of drywall

Drywall sheets are very widespread during installation not only in Russia, but also in countries North America and Europe because:

• now drywall instead of plaster is used more often due to the fact that it involves the conduct of exclusively “dry” work, which greatly facilitates the entire installation process;
• many people wonder which drywall or plaster is better when it comes to soundproofing or thermal insulation of a room, here the answer is simple - drywall definitely wins;
• drywall sheets have the ability to "breathe" - this is due to the fact that the material constantly absorbs excess moisture and later gives it away, this property allows drywall to maintain an optimal microclimate in the room;
• the material is quite flexible and elastic, therefore it is suitable not only for sheathing, but also for creating decorated structures various forms from smooth lines to any geometric shapes;
• working with drywall takes much less time, and also requires less effort, skills and knowledge;
• drywall constructions suggest additional insulation premises (if necessary), this is very much in demand in cold climates.

At in large numbers The advantages of drywall sheets have disadvantages:

• it is not recommended to use it if the room has low ceilings, because the plasterboard has the property of "eating up" the space due to its volume and frame method fastenings;
• during installation, the material must not be left without finishing, which will require additional materials and time costs;
• ordinary drywall sheets will not survive a flood or other serious wetting, it will bend a lot and even when dry it will not return to its previous shape, while it will not withstand strong objects and decorations, for this it will have to be strengthened in advance, which will take quite a lot of time.

What is better plaster or drywall?

To answer the question posed, it is necessary to understand for what situations, what material is most effective. Drywall is usually used if installation work must be completed as soon as possible, this is due to the fact that it does not need to be applied in several layers, like plaster and wait for it to dry completely, which can take a whole day. After installation, gypsum boards can be immediately finished and decorated, while they perfectly hide all communications, such as ventilation, telephone wires, and so on, without replacing the intended design solution.

There are cases when from adverse climatic conditions or improper wall finishing, they become of poor quality and poorly prepared for the next stage of finishing, in such a situation it is better to use drywall, because it is not picky about the quality of the walls, the plaster clearly loses here. It is worth noting here that this is the only option that is compatible with additional soundproofing and thermal insulation, because the design is very well adapted to this.

Drywall is very practical if the design of the room requires precisely painting the walls or ceiling, because it turns out to be perfectly smooth without microcracks and scratches (unlike plaster), which the paint will immediately emphasize and make more obvious.

As for the cases when the use of plaster will be a more advantageous option, these include cases when the finished room is subjected to serious temperature changes, for example, it is not heated for a long time in the cold season.

Also, plaster is indispensable when it comes to finishing. small spaces with low ceiling, it not only does not “steal” extra centimeters, but is also a universal finishing material, it simultaneously levels the surface and decorates it, this is very important if country style or Provence is chosen. Plaster will do a good job if it is supposed to place enough dimensional decor items on the walls in the room. From all of the above, the conclusion follows, when asked what is better plaster or drywall, the answer cannot be obvious, it all depends on the specific conditions, whether it is the quality of the walls, the qualifications of the master or the area of ​​\u200b\u200bthe room.

Each person has their own opinion on the issue of surface finishing in the apartment. To do right choice, it is important to consider the properties and characteristics of building materials used in wall decoration. However, we note that there are more masters who create plasterboard masterpieces than good plasterers.

Drywall or plaster?

This material is also called dry plaster, because it contains a dry mixture of gypsum. The outer part is pressed cardboard. Among other finishing building materials in the US and Europe, drywall is in the lead. It is convenient to use it for leveling walls, as it gives a smooth, even surface. After installing drywall, the surface only needs to be covered with putty, and then apply the finishing method of your choice.

Plasterboard align walls and ceilings indoors, create various designs. The main thing - normal humidity in room. High humidity adversely affects the material, but there is an alternative in this situation. There are sheets that, to a certain extent, withstand high humidity - GKLv. But no matter what drywall is chosen, anyone will help to realize unusual fantasies, being in the hands of a good master.

Advantages of drywall

1. Sheathing surfaces with dry plaster is easy. Almost everyone can do this without resorting to the help of professionals.
2. Plasterboard levels surfaces with deviations of up to 6 cm - a better result than plaster.
3. They work with the material without being distracted by breaks, while the drying of the layers of plaster has to wait.
4. Installation of drywall is a clean job, after which there is no strong dust, dirt, as happens when mixing plaster.
5. Communications are hidden under sheets of dry gypsum: electrical wires, communication cables, pipes.

When creating a frame between the wall and drywall sheets, there is room for insulation, which allows you to keep warm in the room.

Positive characteristics

• Environmentally friendly material.
• Regulates indoor humidity.
• Let air through.
• Serves as an energy-saving and soundproofing material.
• It does not create problems in processing, it is easy to work with it.
• At proper handling bends and helps to create designs of complex outlines.
• It is intended for alignment of surfaces and division of space.
• Mounted using a profile and adhesive method.
• Helps create interesting schemes lighting with built-in luminaires.

disadvantages

1. On surfaces lined with this building material it is undesirable to place heavy objects.
2. Finishing with dry plaster is not the final stage; you still need to walk on the surface with putty or decorate the walls in other ways.
3. Reduces the volume of the room.
4. Installed sheets are fragile, you will have to avoid mechanical damage.

Plaster

This is a finishing material designed for leveling walls and ceilings. A plaster mixture is made from gypsum or cement, lime with the addition of additives that give the material additional properties.

Types of plaster

In turn, they are divided into ordinary and improved mixtures. In the latter, waterproofing and sound-absorbing substances are added. There are decorative plasters, which include coloring pigments.

Plaster mixes are produced on water based and with content epoxy resins and polyurethanes. The latter are most often used only for surface treatment indoors.

Advantages of plaster

1. After alignment wet plaster repairs will not be required for many years (except for finishing).
2. This option is cheaper than drywall.
3. Surfaces after plastering become durable, strong, reliable, resistant to damage, scratches, dents.
4. After plastering, it is allowed to drive nails into the walls or hang heavy objects.
5. Plaster creates textured surfaces.
6. When using plaster on a wall the homogeneous, moisture resistant layer is formed.
7. You do not have to process the seams that remain after applying drywall.

Positive characteristics of plaster

• The material is moisture resistant.
• Resistant to temperature changes.
• Environmentally friendly, vapor permeable, fireproof, non-shrink, heat-insulating, sound-proof.
• Plastered walls do not need post-treatment.

Disadvantages of plaster

1. The process of applying the mixture to any surface is long, with breaks for drying the layer.
2. The more irregularities, the higher the material consumption.
3. In order to avoid cracks in the surface, it is sometimes necessary to apply a reinforcing mesh, which increases costs.

For plastering walls you will need experienced master, since it is very difficult to cope with this task on your own.

findings

• If you have to level too curved walls, it is important to understand that the consumption of wet plaster will be very high. It is better to use drywall.
• Drywall makes the walls perfectly flat. With further finishing, the consumption of the material used is reduced. When leveling the walls with wet plaster, it is not necessary to putty the walls if you are going to glue thick wallpapers. Otherwise, you will have to smooth the surface.
• A good plasterer is much more difficult to find than a person to level the walls with drywall. As a rule, professional plasterers have a schedule in advance. And often the master has no desire to take on a small amount of work, since they are in demand and there is a choice.
• If you plaster the walls, then it will not work to calculate exactly how much material will go away. With drywall, you will calculate everything to the centimeter.

• Drywall allows you to make extraordinary ledges, multi-level structures, creative elements.
• A layer of plaster requires a certain temperature to dry.
• Cardboard afraid high humidity, and if you buy a moisture resistant one, it will cost more.

Looking at finishing options uneven walls, and after weighing all the pros and cons, you can make a choice - plaster or drywall. When choosing, it is important to take into account the cost of work and material, technological difficulties and deadlines. construction works. Determine what is more important to you - extra centimeters or insulation.

In contact with

When building or repairing a house or apartment, the question arises: how to align the internal walls before decorative trim? After all, the quality of the surface of enclosing structures is sometimes far from ideal. If a house is being built for oneself, then there is still an opportunity to control the quality of the walls, but in an old house or apartment there is no such possibility.

The classic leveling method is plaster. A solution is prepared for it based on binders, aggregates and water. Although the composition changes over time, the technology remains the same for many centuries - applying the mortar to the walls and leveling it with tools or mechanisms. If plasters based on and were previously used, now mixtures have also been developed that are mixed and packaged at the factory in bags. Drywall is also used instead of plaster. This material is relatively new, but safe and easy to install. What is cheaper to level the walls, drywall or plaster? What are the features of the use of these materials? Let's consider in more detail.

Pros and cons of plaster

Plaster is made from a mixture of binder (Portland cement, lime, gypsum, clay), filler (sand, stone chips, sawdust) and additives. Depending on the composition and manufacturer, it has different properties and is suitable for different applications, but there are unifying characteristics. The positives include:

• Strength. Regardless of the composition, properly applied plaster has sufficient strength characteristics to serve for a long time - up to several decades. It also better tolerates external mechanical stress.
• The possibility of choosing a mixture for specific operating conditions.
• Existence decorative plaster which does not require puttying and painting. This reduces the cost of work, although it is quite expensive in itself.
• Simplicity and reliability of fasteners for home electronics, appliances, furniture - it is enough to use standard dowels.

The disadvantages include:

• Difficulty of application. For a good result, you must have sufficient skills and experience. Ate the mixture is prepared for construction site- it is necessary to carefully monitor the quality of the components and their proportion. Finished plaster, although it has predictable characteristics, is more expensive.
• If the walls are very uneven, then a large leveling layer is applied. For its fastening, additional processing of the wall is necessary to improve adhesion, the use of a reinforcing mesh.
• The need to select the characteristics of the plaster mixture for the material of the walls.
• Since the process is “wet”, the floor and ceiling are more contaminated during operation.
• After application, it is required to observe the temperature and humidity characteristics of the air in the room for uniform and quick drying.

Features of leveling drywall (GK).

The second option for leveling walls and partitions are plasterboard sheets (GKL). When is it better to use drywall instead of plaster walls? What are its features? The advantages of leveling these materials include:

• Ease of installation. Although drywall also requires skill, it is easier for a non-specialist to learn than plastering.
• Speed ​​- if after applying the plaster it is necessary to wait until it dries, then you can putty the HA immediately after fixing.
• The distance from the draft wall to the front surface of the sheet is allowed to be large, while plastering more than 50 mm is problematic and expensive to apply.
• Between the draft wall and the GK sheet, a layer of insulation can be laid, which improves the thermal performance of the structure.
• Possibility of application in wet rooms when using sheets of the appropriate type (moisture resistant).
• Since the process is “dry”, the room is less polluted during operation.
• In the empty space behind the sheet, it is allowed to build engineering communications without gating - electrical wiring, water, sewer and heating pipes.

Disadvantages:

• The thickness of the structure takes up part of the useful volume of the room.
• Difficulty fixing furniture household appliances. The drywall itself is fragile, which means it must be fixed to the draft wall using special mortgages and brackets.
• The surface of the GKL is easier to damage or destroy.
• Domestic rodents may appear in the space between the wall and the sheet (this is more relevant for private houses).

Which is cheaper, drywall or plaster walls? It depends on the various factors. The cost of plastering work on beacons is approximately equal to or more than the price of installing drywall sheets using guides. The cost of the materials themselves also depends on the conditions of their use. With a plaster layer thickness of up to 10 mm, the cost square meter surfaces treated with dry mortar or standard drywall, are comparable to each other. However, if the layer increases, then the plaster becomes more expensive. And vice versa - if the walls are even and do not require a large layer building mix, processing it will be cheaper.

It is advantageous to use GKL for uneven draft walls, when a large layer of plaster is required for leveling. If a small layer is required, then vice versa. Also, the choice depends on the cost of work in a particular region, the availability of materials, the planned design of the room. The choice is made after calculating and comparing the cost and features of both options.
