Features of the

Before using glue for mounting drywall, you must prepare the surface. To do this, it should be cleaned of dust and dirt, primed in two layers, which will enhance the adhesion of the surface with the finishing material and strengthen it.

The priming is performed in several stages:

  • the first layer is applied in an even layer to the surface and left to dry;
  • the second layer is applied after 24 hours with undiluted mixture and kept for one day.

Glue for drywall has some advantages over other methods of fastening the material:

  • Fast installation. The use of an adhesive will reduce the time it takes to install drywall boards.
  • Fast hardening - within 1-1.5 hours. While the glue is applied to the entire surface, it will be possible to proceed with the putty.
  • Simple to use. The adhesive is easy to prepare and apply due to its high plasticity. An equally important point is that there is no need to pre-level the surface.
  • Profitability. Compared to other methods of fastening drywall, the use of glue will reduce costs several times. In addition, the area of ​​the room will be reduced by a maximum of 20 mm on each side, while the installation of the slabs on the frame will reduce the area by 40 mm.

These facts justify why it is better to choose a drywall adhesive rather than a different fixing method.

There are 4 types of drywall glue:

  • mounting;
  • gypsum-based mastic;
  • specialized adhesive;
  • polyurethane foam.

Assembly adhesive requires compliance with a special cooking technology, which is indicated on the package. This type of glue is applied to the prepared surface with a spatula in a circular motion. During the installation of drywall boards, care must be taken to ensure uniformity. For these purposes, it is best to use the level at which the plates are installed. You can change the position of the installed sheet within the next 10 minutes.

Part gypsum-based mastics includes an adhesive component and lime. The glue is dissolved in water and left for 14 hours to swell the granules. Then add lime, diluted with liquid. Gypsum mastic has good adhesion. Grasping takes place within 50 minutes.

Specialized adhesive sold in cylinders of 750 ml. It is applied in a ratio of 1 balloon to 15 square meters. Such glue also has good adhesion, but it can only be used at the same height around the entire perimeter of the room.

Gluing drywall with polyurethane foam includes:

  • the presence of about 10 holes along the entire perimeter of the panel;
  • foam stickers at a distance of 10 cm from the holes;
  • installation of gypsum board sheets on the wall and strengthening with screws;
  • pouring foam into the holes made.

Before finishing the wall with plasterboard, you need to assess the overall situation.

When it comes to surfaces with defects, the use of putty will help save the situation. However, this can only be done by an experienced technician. The process of leveling the wall is quite a long and painstaking work.Tiled drywall can be used to level depressions and bumps.

Scope of application

Let's figure out what compounds are used in various cases when installing gypsum board.

  • Gypsum mastic is used for gluing the gypsum board to the brick surface. The gypsum-based composition is economical to use - about 5 kg of glue is enough for 1 square meter.
  • Polyurethane foam, which is notable for its low price, copes well with the same task. One 750 ml cylinder can glue 10 square meters of surface. Most people use polyurethane foam to insulate their homes. However, there is one drawback of this composition: the expanding ability, which implies the subsequent fastening of the sheets using dowels and self-tapping screws. And these are additional costs and efforts.
  • The adhesive is used for decorative plaster, making the surface original and interesting.

  • Adhesives based on gypsum or polyurethane can adhere drywall sheets to concrete surfaces. In addition to gypsum mastic, polyurethane foam, cement compositions and putties can also be used for concrete finishing.
  • A specialized adhesive is used for gluing drywall to expanded polystyrene.
  • Special adhesive for tiles is a silicone composition for gluing tiles to gypsum boards. Such a composition is not afraid of high humidity and temperature extremes, which allows it to be used in bathrooms. Sealant is also used to fill the joints between tiles, transparent or colored glue is suitable for this.
  • Bonding skirting boards and drywall. To bond these surfaces together, you can use a silicone sealant or all-purpose adhesive.

Consumption

As a rule, the consumption of glue for drywall per 1 m2 is indicated on the package. However, this value is influenced by the flatness of the surface:

  • for gluing on a flat surface, the consumption per 1 m2 is 1⁄2 kg of the mixture;
  • for wall mounting with visible defects - up to 5 kg;
  • when mounted on a wall with tubercles up to 2 cm - up to 6 kg;
  • for gluing tiled partitions, up to 2 kg of mixture per 1 square meter is used.

Tips & Tricks

Take advantage of expert advice and the process of gluing drywall will go quickly and smoothly.

How to properly prepare GKL glue?

Glue for drywall is quite easy to prepare, for this you need a mixer with a whisk or an attachment drill. The use of the latter is not always successful - a good solution is rarely obtained.

There is one important rule that must be adhered to when preparing any solutions, including an adhesive for drywall: not water is poured into powder, but powder is poured into liquid. Violation of this rule will lead to deterioration of the solution - it turns out with lumps.

Image

You should take a container for the resulting solution, pour water on a third of the volume, pour dry powder until a small hill of powder appears. After that, you can stir the mixture using the selected tool until a homogeneous composition is obtained. The density can be adjusted by adding water or adding dry powder.

There is one important point to keep in mind. You can thicken or dilute the solution in the next 5 minutes, otherwise the glue will become non-plastic. With the correct preparation of the glue, the composition can be used within 40 minutes.

A few tips to help when installing drywall boards:

  1. The glue is applied in four rows on the surface: the first two rows are at the edges, the other two are in the center. At the same time, the distance between them should remain the same - about 40 cm.
  2. A pair of metal profiles can be used to align the sheets. The level will also be useful.
  3. The edges of the glued sheets are lined with glue solution.

How to glue drywall?

Plasterboard installation will not be particularly difficult, even for inexperienced people. After surface preparation, the adhesive is applied to the drywall, pressed against the wall and aligned along the outlined lines.

After that, you should press down the sheet a little harder so that the glue spreads over the surface and the drywall fits snugly. Finally, drywall is putty. This technique will help save some floor space.

The preparation of the base is as follows. A surface primer is required, and the manufacture of strobes for wires. If the base is brick, then special attention should be paid to the elimination of roughness and irregularities. For these purposes, putty or drywall strips are used.

Foam blocks, gas blocks do not create similar problems, but if there are some irregularities, then gypsum solutions are used.

How is drywall attached to the adhesive mortar?

Basically, the result of the work depends on which glue was originally chosen for the repair and for which surface. For example, an uneven surface will require more glue than a smooth one. The thickness of the mortar layer eliminates the roughness of the base.

For substrates without drops (concrete, plastered walls), the process of gluing drywall looks like this:

  • make grooves for the cable and holes for sockets;
  • a primer mixture is applied to a clean surface, in the case when the glue does not stick, the quartz filler will help to solve the problem;
  • holes are made on drywall sheets for electrical equipment;
Image
Image
  • glue is applied with a spatula, the excess is removed;
  • the plate is placed face down;
  • before the sticker, it is slightly raised and the cables are guided into the holes;
  • drywall is applied and tighter attached to the wall by light taps of the hand.

For surfaces with irregularities up to 20 mm, gluing with plasterboard is different., but the preparation, the primer does not differ from the previous version.

  • A little more glue is prepared than for a flat surface, it is applied to the gypsum board not with a spatula, but in separate piles. Thus, irregularities are eliminated and a reliable fixation of the sheet on the surface will be ensured.
  • They are pasted over starting from the output of the cables and the clamping of the GKL sheet, which is hooked onto the base. It is better to carry out repairs in the company of people, so that one holds the material and helps to press it.
  • At the end, the plane is checked to determine where the sheet needs to be pressed harder. If there are such areas, they are lined up until the desired results are obtained.

For a surface with large differences (more than 20 mm), the step-by-step instructions are as follows:

  • get rid of fragile plaster areas;
  • primed the surface;
  • beacons are made - strips 10 cm wide are cut from the sheet, which are placed along the perimeter of the base and vertically, then they are fixed with an adhesive solution;
Image
Image
Image
Image
Image
Image
  • the main GKL plates are installed on the beacons with the help of glue, which is applied along the line, then it is lifted and pressed against the beacons, and if all the rules are observed, installation will not be difficult;
  • joints are treated with putty or glue;
  • after drying it should be primed again and putty.

Can the ceiling be pasted over with plasterboard?

When finishing the ceiling, many people prefer this material. But in this case, predominantly thin sheets are used. And also a lot depends on the quality of the glue.

Experts identify several types of gypsum board fastening. For the sake of reliability, stops are often used that press on the sheet and rest against the floor, thereby preventing the drywall from coming off until the glue dries. You can use wooden blocks as them. Some argue that to facilitate the work, you can glue the sheets, cutting them into parts, and not whole.
