Installation of drywall on the glue .How to glue plasterboard

One of the most popular materials for finishing the rough walls is drywall.This is not surprising, since the cast is easy to operate, it allows you to create a perfectly flat surface, and is much cheaper than plaster.Nevertheless, the classical method of installation involves the use of metal profiles, it imposes certain limitations.Therefore, the method of gluing drywall is becoming urgent, and is rapidly gaining popularity.

Advantages and disadvantages of using glue

drywall adhesive - a fairly simple procedure.But, like any process, it has its advantages and disadvantages.To clear pluses include:

  • speed of work performance (productivity increased twice),
  • no additional cost to the user's profile,
  • minimal reduction of living space,
  • possibility of adjusting the serious defects without using plaster,
  • reliability (adhesive allows you to savethe integrity of the gypsum sheet, so it will not crumble),
  • strength (use glue to create a lot more reference points, which makes the construction much stronger).

In these figures use the profile seems completely irrelevant, however it is not.When it comes to the creation of multi-level structures, the metal can not do without.Furthermore, for the ceiling plates are mounted only on profile.Another significant drawback of the method of gluing - direct contact with the wall.The only thing that is afraid of gypsum - a moisture.If the wall or preet is located on the north side, it is in 90% of cases will mean that the plaster gets wet.As a result, the wall surface will be destroyed.Of course, this problem is easy enough to solve, but will require additional costs.Less significant but also important drawback - the inability to use this isolation.Some experts advise sticking to the back of the plaster and foam to produce gluing already on it.This process is at odds with building codes and greatly reduces wear design.Any mechanical shock can lead to the fact that the edges of the foam come off and the wall will collapse.

Species drywall and especially their use

Despite the fact that only three types of drywall, the scope of each type is not particularly limited.To glued construction was the most robust, it is necessary to consider the application in detail:

  • ceiling,
  • wall,
  • moisture resistant.

plasterboard ceiling is the most thin and light.Its width of only 0.8 cm. In this case, the strength of it is not inferior to the Wall (with a width of 1.2 cm).The difference is that when mounted on the profile of the ceiling drywall screws crumbles from much stronger and can not stand the strain.When it comes to bonding technology, the sheet securely adheres the entire plane to the surface and creates a solid foundation.It is advisable to use this option to save as thinner sheets are cheaper.

Wall drywall is relevant only for the installation of bulkheads and falshsten.The technology is quite simple, but includes elements from metal sheets.It is necessary to set the upper and lower rails and fasten it to the first page, then paste the entire plane of the small pieces of plaster, a width equal to the planned wall.Next fit mineral wool for insulation, and the second sheet is attached.Screwed it need not, as a rule, the guides are not set.The advent of water-resistant drywall turned an idea about this stuff and repeatedly expanded the possibilities of its application.Traditionally, it is used for the arrangement of the toilet and the bathroom, but when it comes to gluing, then apply it to everything walls, at risk.The only material that does not preet - a shell rock.All other varieties of stones, blocks and monoliths are prone to accumulation of moisture and release.It gradually penetrates the gypsum and violates the integrity of the design.For example, in the case of concrete, the plaster gets wet after 2-3 years, 4-5 years for silicates, red brick - 6-10 years.

condensation process is enhanced due to the temperature difference.The phenomenon is observed in winter.Avoid it completely impossible, but a few high-quality thermal insulation reduces the moisture accumulation.This is especially true north of the house, since it is the least exposed to the sun's rays, therefore, poorly warms and dries.Moisture resistant gypsum solves all of these issues.Moisture resistant drywall has a water-repellent coating on one side only, it is highlighted.If the installation is made on the inner walls of the room, the waterproof layer is set facing outwards when the external - to the wall face.

Drywall Adhesive what to choose

Actually adhesive concept for drywall rather abstract as absolutely any adhesive mixture with the addition of gypsum to replace already existing analogs, in some cases it will even more reliable than the finished mixture (if itcomes to large irregularities to be filled, the adhesive is prepared from 3 parts of cement, 2 parts of any adhesive and 1 part gypsum).If there is no desire to come up with its own solution, we recommend that you turn to proven companies, including:

  • Knauf Perlfix,
  • Quelyd Myural,
  • «Brozex Hyper Contact»,
  • «Perlgips»,
  • «Volma-mountingFrost »,
  • « Unifiks ".

Knauf - a world leader in the manufacture of mixtures for building and finishing works.The company products are considered to be one of the highest quality and meets all European standards.This adhesive for drywall, the price is really justified by the quality.Imazhe1

Outperforms legendary German, only French company Quelyd.This is reflected in the cost.Despite an active campaign for drywall adhesive is different only in that the sold in the diluted form.This allows you to achieve the most durable adhesion, but with mixer (drill with a special nozzle), any other product is practically no yield Quelyd.Accordingly, the main advantage - it is a minimum of dirt and increase the speed of work.Other manufacturers are domestic firms, the price of one bag of adhesive ranges from 200 to 220 rubles.On quality they are virtually indistinguishable, so the choice depends more on the distribution.From practice it should be noted that although the Knauf Perlfix and is 250-280 rubles.per bag, it is much safer in a private building.Moreover, the material consumption is slightly less than the other analogs.

How to glue the drywall on the walls?

process though it seems simple, yet requires careful preparation and strict compliance with the instructions, otherwise there is a risk that the adhesive will fall off.To begin, consider the preparatory stage:

  • wall, regardless of the type of surface, you need to clean up, use mesh for plastering trowel plaster, then a dry cloth (made to remove elements that have separated from the wall),
  • below the surface need to tap rubbera hammer, and then overwrite (this will completely remove all loose items),
  • wall ready for primer, the paint should be added preservatives and additives against mold and mildew,
  • primed to be at least two times at intervals of 45-50 minutes (I regret the ground is impossible, as the surface to be processed without gaps, and she paints soak into the top layer of at least a few millimeters, to create a reliable protective cover).

then sticking plasterboard wall.Several options:

  • on a flat surface,
  • on brick,
  • on large bumps.

Each type of gluing will be different from each other, so stop on them in more detail and consider all the details of the process.

glue drywall on a flat surface

Under the smooth surface should be understood monolithic concrete structure or plastered stone.Although the surface is not perfectly smooth, it still allows you to do without a serious correction sheet.To work you will need:

  • utensils for breeding of glue,
  • drill with a drill on a stone,
  • set of dowels and screws,
  • building knife,
  • rule,
  • level,
  • rope or fishing line.

Despite the fact that the visual surface looks smooth, in practice it usually turns out that it has certain defects.In the best case, the wall will be tilted up or down (right / left), and at worst - will appear "belly."Sheets of drywall weigh quite a lot, so they act out difficult slope.To simplify the procedure, immediately set the beacons.

Then everything is simple, on the back side of the sheet is applied to the adhesive, the breast should be located at a distance of 25 cm from each other.Before applying the sheet to the wall, it is advisable to sprinkle it with water from a spray bottle, wet rag, roller, etc.strictly not allowed.Once the first sheet is pressed, it is necessary to adjust for the beacon, and secured with dowels (sufficiently centered on the edges of the sheet to screw the two screws).At the beginning of the lower number is set, then the top.Seams should immediately promazyvat glue, in this case, it will replace the putty, as well as link the material, not only the wall, but also among themselves.When using this technology as much as possible to save space and in addition, virtually no voids.In terms of reliability, gypsum tiles stand or any other decorative material.If you plan to mount the shelves or wall cabinets, the fasteners must necessarily go to the main wall.To this end, the recommended anchorage depth plus the distance from the wall to the sheet of drywall plus its width.

glue plasterboard on the masonry

Unlike previous methods are not significant.However, the clutch requires a certain defects.This means that the adhesive is not evenly distributed across the surface.As a result - not the sheet is fixed securely.Therefore, the surface should be prepared.It is done as follows:

  • cut into one of the sheets into small rectangles (10x15 cm),
  • stick them on the wall at a distance of 10-15 cm from each other,
  • rule check for the presence of cavities, or "belly»,
  • setbeacons.

Next breast adhesive applied directly on the blank, which leans against the sheet.After the plaster is adhered, it is necessary to check the level.If everything smoothly, fixed dowels.As in the previous method, the seams are coated adhesive residues.Imazhesh

technology is not universal and depends on the type of stone in many ways.Red brick works seamlessly with any kind of adhesive, the same is true with respect to the foam concrete.If it is a silicate or cinder block, then the question of how the glue to glue plasterboard, becomes relevant.Although ready mixes are considered universal, in practice this is not always confirmed.Therefore, the adhesive selected must be modernized.For this purpose, 10 kg of glue is added:

  • 1 kg of plaster,
  • 0,5 liter of PVA glue,
  • antimoroznye additives.

basic chemicals silicate bricks - "silicon" in its purest form is the sand.The physical properties of the material such that its thermal conductivity is higher than 100%.This means that during the cold season, he immediately freezes, and in the warm - warm.Such temperature jumps badly affect the adhesive, and require additional binders (the simplest of these PVA).

thermal conductivity of cinder block is much lower, but the material is not too well with glue, so the addition of these additives to the same volume, you need to add another 2 kg of cement and 0.5 liters of PVA.This will create a perfectly solid mixture, which will provide a monolithic connection with the wall plaster.

gypsum glue on uneven surfaces

Complexities no in this case.The procedure repeats almost drywall process for masonry, except that instead of the substrate sheet, is glued a little.Another option - use a homemade mixture in the section devoted to the choice of adhesive.It is worth noting that the difference between these options cardinal.Using multiple, substrates bonded together more reliably, but takes up considerably more space is not adhesive solution in the full sense of the word, but reduces the space from wall to gypsum.It requires a strong fixation with dowels (on the edges and in the middle).To read more about how to install drywall on the adhesive see the video.
