One of the most popular materials for the draft walls is plasterboard. This is not surprising, since it is easy to work with a plaster, it allows you to create a perfectly smooth surface, and it is also much cheaper than plaster. Nevertheless, the classic installation method involves the use of metal profiles, it imposes certain limitations. Therefore, today the method of sticking plasterboard becomes relevant and rapidly gaining popularity.

Advantages and disadvantages of glue use
Installation of plasterboard on glue - the procedure is quite simple. But, like any technological process, it has its advantages and disadvantages. The obvious advantages include:
- the speed of work (labor productivity is halved),
- lack of additional profile costs
- minimum decrease in residential space,
- ability to adjust serious defects without the use of plaster,
- reliability (glue allows you to maintain the integrity of the gypsum sheet, so it will not crumble),
- strength (the use of glue allows you to create much more reference points, which makes the design much stronger).
With such indicators, the use of the profile seems completely irrelevant, nevertheless it is not. If we are talking about creating multi-level structures, without metal can not do. In addition, the ceiling sheets are mounted only on the profile. Another weighty lack of a blowing method is direct contact with the wall. The only thing that is afraid of plaster is moisture. If the wall is preferably or located on the north side, this in 90% of cases will mean that the gypsum is wet. As a result, the surface of the wall will be destroyed. Naturally, this problem is fairly easy to solve, but additional costs will be required. Less significant, but also an important disadvantage is the impossibility of using isolation. Some specialists advise the foam plastic to the back of the gypsum and make a sticking already on him. This method is in incision with the construction standards and strongly lowers the wear resistance of the structure. Any mechanical blow can lead to the fact that the edges of the foam will be torn off and the wall will collapse.
Varieties of drywall and the features of their use
Despite the fact that the varieties of drywall are only three, the scope of the use of each species is practically not limited. In order for the glued design to be as strong as possible, it is necessary to consider the use in detail:
- ceiling
- wall
- moisture-resistant.
Ceiling plasterboard is the thinnest and easy. Its width is only 0.8 cm. At the same time, in strength, it is not inferior to the wall (with a width of 1.2 cm). The difference is that when installing on the profile, the ceiling plasterboard crumbles from the screws much stronger and does not make mechanical loads. If we are talking about gluing technology, the sheet is reliably adjacent to the entire plane to the surface and creates a solid foundation. It is advisable to use this option for savings, since thinner sheets are cheaper.
Wall drywall is relevant only for montage of bulkhead and falseland. The technology is quite simple, but includes elements from metal profile. It is necessary to install the upper and lower guides and fasten the first sheet to them, then glove the small pieces of gypsum throughout the plane, the width of the planned wall. Further, the minvat is laid for sound insulation, and the second sheet is glued. It is not necessary to fasten it, as a rule, the guides are not installed. The appearance of moisture-resistant drywall turned the idea of \u200b\u200bthis material and has repeatedly expanded its use. Traditionally, it is used to arrange toilet and bathroom, but if we are talking about sticking, then it is used to arrange the walls in the risk area. The only material that does not exceed is a seven. All other varieties of stones, blocks and monoliths are prone to accumulation and allocation of moisture. It gradually penetrates the gypsum and violates the integrity of its design. Suppose, if we are talking about concrete, then the gypsum is worst after 2-3 years, for silicates for 4-5 years, red brick - 6-10 years.
The condensation process is enhanced due to the temperature difference. The phenomenon is observed in winter. It is completely impossible to avoid it, but high-quality thermal insulation slightly reduces the accumulation of moisture. This is especially true of the northern part of the house, as it is least under the influence of sunlight, therefore, it is bad warm and dries. Moisture-resistant plaster solves all these issues. Moisture-resistant plasterboard has a water-repellent coating on one side, it is highlighted by color. If the installation is made on the inner walls of the room, the waterproof layer is established by the face outside, if on the external face to the wall.
Glue for plasterboard what to choose
In fact, the concept of glue for drywall is very abstract, since there is absolutely any adhesive mixture with the addition of gypsum will replace ready-made analogues, in some cases it will be even more reliable than the finished mixtures (if it comes to large irregularities that need to be filled prepare from 3 parts of cement, 2 parts of any glue and 1 part of the gypsum). If there is no desire to invent your own solution, we recommend contacting verified firms, including:
- Knauf Perlfix,
- Quelyd Muyral,
- "Brozex hyper contact",
- "PerlGIPS",
- "Montage-Montage-Frost-Building",
- "Unifix".
Knauf is a global leader in the production of mixtures for construction and finishing works. The company's products are considered one of the highest quality and meets all European standards and standards. This is a glue for plasterboard, the price of which is really justified with quality. 
Excellence in the quality of the legendary Germans, only the French company Quelyd. This is reflected in the cost. Despite the active advertising campaign, the glue for drywall is different only by the fact that it is sold already in a divided form. This allows you to achieve the maximum strong gluing, but if there is an electric mixer (drill with a special nozzle), any other product will not give up Quelyd. Accordingly, the main advantage is the minimum of dirt and increase the speed of work. The remaining manufacturers are domestic firms, the price of one bag of glue ranges from 200 to 220 rubles. In terms of quality, they practically do not differ anything, so the selection depends rather from the distribution. From practice it should be noted that although Knauf Perlfix costs 250-280 rubles. For a bag, in private construction it is much more reliable. In addition, the consumption of the material is somewhat less than that of other analogues.
How to glue drywall on the walls?
The process, although it seems simple, still requires careful preparation and accurate execution of the instruction, otherwise there is a risk that glue falls off. To begin with, consider the preparatory stage:
- the wall, regardless of the type of surface, you need to clean up, use a mesh for grouting plaster, then dry rags (done to remove the items that separated from the wall),
- next, the surface must be sprinkled with a rubber hammer, and get lost again (this will allow you to completely remove all the loose items),
- the wall is ready for primer, antiseptics and additives against fungus and mold should be added to the paint.
- it follows at least two times with interruptions of 45-50 minutes (the soil cannot be sorry, since the surface must be processed without skips, and the paint itself is absorbed into the top layer at least a few millimeters to create a reliable protective cover).
Then glue drywall on the wall. Several options:
- on a flat surface
- on a brick
- on large irregularities.
Each of the species of sticking will differ from each other, so we will dwell on them in more detail and consider all the subtleties of the technological process.
Gypsum Gypsum on a Smooth Surface
Under a flat surface, monolithic concrete structures or plastered stone should be understood. Although this surface is not perfect smooth, it still allows you to do without a serious leaf correction. To work, you will need:
- utensils for breeding glue,
- drill with a stone drill,
- set of dowels with screws,
- construction knife,
- rule
- level,
- rope or fishing line.
Despite the fact that a visually surface looks smooth, it usually turns out that it has certain defects. In the best embodiment, the wall will have a tilt up or down (right / left), in worst - "Puzo" will appear. Sheets of drywall weigh quite a lot, so it's difficult to play the slope. To simplify the procedure, immediately set the beacons.
Further, everything is simple, glue is applied on the back of the sheet, breasts should be located 25 cm apart from each other. Before applying a sheet to the wall, it is desirable to sprinkle it with water from the pulverizer, watering with a cloth, roller, etc. It is categorically not allowed. After the first sheet is pressed, it is necessary to adjust it along the lighthouse, and fix with the help of a dowel (enough on the edges of the center of the sheet to screw two screws. At the beginning, the lower row is installed, then the upper one. The seams must immediately miss glue, in this case it will replace the putty, and also connects the material not only with the wall, but also among themselves. When using this technology, the place is maximally saved, in addition, there will be practically no emptiness. From the point of view of reliability, plaster will withstand a tile or any other decorative material. If you plan to mount the shelves or hinged cabinets, then the fasteners must be found in the main wall. To do this, the recommended depth of the attachments plus the width is plusing its width plus.
Gypsum Marking Masonry
Differences from the previous method are not significant. Nevertheless, the masonry assumes the presence of certain defects. This means that glue will not evenly be distributed over the surface. As a result, the sheet is not secure. Therefore, the surface must be prepared. It is done as follows:
- cut one of the sheets into small rectangles (10x15 cm),
- stick them on the wall at a distance of 10-15 cm from each other,
- check the rules for the presence of a depression or "Puz",
- install lighthouses.
Next, glue breasts are applied directly on the workpiece, which lets the sheet. After the gypsum is glued, it must be checked by level. If everything is smoothly fixed by dowels. As in the previous method, the seams are drained by the residues of glue. 
The technology is not universal and largely depends on the type of stone. Red brick interacts perfectly with any kind of glue, the same is true in relation to foam concrete. If we are talking about silicate or slag blocks, the question of which glitter is glittering is becoming relevant. Although the finished mixtures are considered universal, in practice it is not always confirmed. Therefore, the selected glue must be upgraded. For this, 10 kg of glue add:
- 1 kg of gypsum,
- 0.5 l glue PVA,
- anti-soul additives.
The main chemical substance of silicate brick is "silicia", in its pure form represents sand. The physical properties of the material are such that its thermal conductivity is above 100%. This means that during the cold season it instantly freezes, and heats up to warm. Such temperatures badly affect the glue and require additional binders (the simplest PVA).
The thermal conductivity of slag blocks is significantly lower, but the material itself does not interact too well with glue, so in addition to the specified additives on the same volume, it is necessary to add 2 kg of cement and 0.5 liters of PVA. This will create a perfectly solid mixture that will provide a monolithic compound of plaster with a wall.
Gypsum sticking on an uneven surface
There are no difficulties in this case. The procedure almost completely repeats the process of mounting the plasterboard on the masonry, by the exception that instead of one substrate sheet, several passes. Another option is the use of a self-made mixture specified in the section dedicated to the selection of glue. It is worth noting that the difference between these options is cardinal. The use of several, glued together substrates is more reliable, but occupies a much larger place, the solution is not glue in full understanding of this word, but allows you to reduce the space from the wall to the gypsum. Requires more powerful fixation using a dowel (at the edges and in the center). To get acquainted in more detail with how to mount plasterboard on the glue, watch the video.
