How to fix drywall to the wall

Today, construction works use a variety of methods for leveling wall surfaces, as well as improving sound and heat insulation. One of the most simple and effective - plasterboard plasterboard (gypsum plasterboard). The use of various methods of fastening sheets due to the type of surface, the curvature of the wall and its actual purpose. In order to understand all the intricacies of this activity and answer the question of how to fix drywall to the wall, it is worth finding out some important points.

Features of the GCR

When arranging rooms with high moisture content (shower or bathroom, plumbing fixtures) it is more expedient to use a special type of gypsum board (GKLV), which has an increased resistance to moisture penetration and the formation of fungal deposits. In most cases, such sheets are available in greenish shades.

In addition, when finishing rooms with high humidity, you can use ordinary drywall (HL), but you need to perform a number of protective operations to increase its moisture resistance: painting, priming or tiling.

Along with the listed types of this material, there is also fire-resistant drywall (GKLO). It is still the same gypsum, but in this embodiment, the base layer is reinforced with reinforcing glass fibers and clay compounds. In sales such sheets are found in pink or red shades.

Considering this or that type of material, it is worth highlighting its advantages and disadvantages. The main advantages of gypsum boards:

• high sound and heat insulation characteristics;
• the ability to hide surface irregularities, electrical wiring, water supply and heating systems;
• simple and quick installation;
• ease of use.

However, along with the advantages, this material has an important major drawback - fragility. The walls of plasterboard sheets are not able to withstand a lot of weight, so before installing all partitions, consider possible ways of attaching various heavy objects: a plasma TV, microwave, speaker system, etc.

The walls are decorated with gypsum plasterboard on galvanized metal rails or by means of adhesive composition. The latter option is more simple and economical, however, it is advisable to use it only with a slight curvature of the surface.

Mounting methods

There are many options for installing drywall sheets to understand the question of how to properly carry out installation, you need to consider the most popular ones: frameless and frame mounting option. The first method is the simplest, because it does not require the construction of a special frame, in this case, the sheets are fixed with a special adhesive.

Frameless mounting option

This mounting option provides for fixing of plasterboard sheets without profiles, so before performing all installation work it is necessary to provide the material with reliable conditions for coupling. This will require a number of activities:

• prepare a solid foundation (all crumbling places and mold deposits should be cleaned, puttied and leveled);
• make sure that the surface is fully protected from freezing and ingress of moisture;
• clean the wall from building dirt, dust and other third-party substances.

It is more expedient to carry out the presented variant of fastening with minimal deviations of curvature values.

To perform all the fixing work you will need to prepare the necessary tools and materials. They include:

• wall plasterboard sheets with a thickness of 12.5 mm;
• dry plaster mix based on gypsum binder;
• capacity for the preparation of the mixture;
• paint / clerical knife;
• the rule;
• roulette and construction level;
• rubber kyivanka;
• jigsaw / hacksaw;
• spatulas.

Having finished with the preparatory activities, we proceed to work. The first step is to take measurements of the wall and map out the future location of the sheets. However, in some cases, with ceiling heights above 2.5 m, it is necessary to dock whole sheets with inserts.

Straight cuts are easiest to carry out with a paint / clerical knife on the ruler, cutting a sheet of drywall on one side and breaking off the excess with the other. Then it remains to cut through the cardboard cover from the rear. Curved or rounded lines are better to do jigsaw / saw with a thin blade.

After completing all the cuts, proceed to the preparation of the adhesive composition. According to the attached instructions to the plaster mix pour out all the ingredients and stir the mass.

By means of a notched trowel, the surface of the sheet is covered with a uniform layer of adhesive composition or with a trowel - small pellets.

Prepared drywall with a little effort is pressed directly to the wall rule. Then with the help of a rubber mallet we knock on the perimeter of the rule, constantly changing its position on the sheet to be glued. After letting the glue dry, we begin to putty the seams and the ceiling gap.

An important point when installing drywall sheets is to leave optimal distances between the joint sheets. So, between the seams should be at least 5 mm, the gaps from the floor are set depending on the width of the future baseboard and the ceiling at least 5 mm. For these purposes, it is convenient to use harvested wooden bars of the required sizes.

Frame mounting option

This method of fixing drywall is more complex and expensive, however, has a number of defining advantages. Advantages compared with the previous method:

• higher sound and heat insulation properties;
• it becomes possible to align the greater curvature of the walls;
• no need for surface preparation;
• it can be applied when warming the freezing walls.

The option of mounting sheets with a profile provides the ability to place connecting cables, wiring and insulation sheets under the drywall.

The framework for fixing gypsum boards can be made of wood (timber with a section of 30 × 50) or galvanized profiles. Wooden construction elements are mounted with screws and dowels-nails.

The frame, made of wood, will cost you a little less, however, the galvanized profile is much easier to work with, and it is less susceptible to destruction.

Thus, it is more expedient to use the latter option in the manufacture of the structure. To implement it will require:

• wall plasterboard sheets with a thickness of 12.5 mm;
• metal hanging fasteners and profiles;
• screws, screws and dowel-nails;
• drill with perforator and cross bat;
• putty and trowel;
• Bulgarian and scissors for metal.

Starting the execution of works, it is necessary to make measurements of the wall, as well as to outline the future places of hanging fixtures and profiles. Along the perimeter of the future decoration, guide profiles are placed: to the ceiling, floor and wall, into which vertical profile strips are inserted with an interval of 40 cm and fixed with hangers. Suspended fasteners are placed at a distance of 80 cm one below the other.

Then the frame is assembled. We fasten the top guide rail to the ceiling with a punch and dowel-nails. Then with the help of a plumb we set and fix the lower guide profile. Then, at the specified intervals, the side elements of the structure are fixed and the bearing guides are inserted. The latter are attached to the outboard fasteners with 4 mm self-tapping screws.

Getting to the placement of drywall. To improve heat and sound insulation, the empty space between the wall and the plates is filled with an isolon or basalt wool. Sheets are attached with 25 mm screws so that the caps are recessed into the material.

In case of plasterboard sheets it is important to consider that a supporting profile should be located under each joint of the plates. In addition, we should not forget about the offset sheets. The seams of the obtained surface and the attachment points of the self-tapping screws are puttied upon completion of the installation work.

Wooden wall paneling

The option of fixing plasterboard sheets to a wooden wall is in many ways similar to work on concrete. Of the features of the installation is to provide a mandatory surface treatment before collecting the structure. All remnants of the previous decoration should be removed from the walls: insulation, communications and other unnecessary materials.

If necessary, in places of formation of dampness or mold, an additional caulker is carried out, after which the surface is cleaned and all external defects are removed. Next, the surface is primed with special compounds and treated with antiseptics.

All other manipulations on the arrangement of the batten and installation are similar to the methods described above.

In the course of carrying out all the plasterboard installation work, it is important to take into account all the proposed recommendations concerning the alignment of the frame and slabs, since this directly proportional to the service life of the future cladding.
