Drywall is an excellent finishing material, indispensable for leveling or building partitions, walls, ceilings.

The article describes the technology of plasterboard wall cladding, describes the methods of wall cladding with drywall sheets.

After reading the article, you can independently, without the help of professionals, sheathe the walls with plasterboard with your own hands.

For wall cladding, drywall has been used for a long time. For example, in Russia, drywall has been widely used since the 50s of the last century. True, the material produced in the XX century did not have such high properties that make it affordable not only in cost, but also in the possible application.

Drywall has a number of advantages over other finishing materials:

- high fire resistance and sound insulation;

- low cost;

- light weight;

- ease of use, practicality and simplicity.

What do you need to know in order to properly apply drywall for wall cladding?

Consider the main points of the technology of wall cladding with plasterboard sheets.

For cladding, various methods of fastening the material are used, frameless or frame.

For a constantly heated room, it is recommended to use drywall with a thickness of at least 12 mm In a summer house, it is advisable to use a moisture-resistant, fire-resistant gypsum board for wall cladding.

Do-it-yourself frameless wall cladding method is based on the use of plasterboard sheets with a thickness of at least 12 mm.

It is more advisable to use this method on a flat surface on which old plaster adheres well. In addition, the wall must be securely installed.

Installation stages are divided into preparatory, installation, finishing.

At the preparatory stage, old paint, wallpaper, plaster, dust, dirt are removed from the surface.

Damaged areas are plastered, cracks are closed. For high-quality sealing of the surface, cracks must be cut to a depth of at least 5 mm when covering them up. The roughness of the surface is checked.

For irregularities of no more than 4 mm, drywall sheets are attached with gypsum or mortar or putty.

With surface irregularities up to 20 mm, the sheets are laid with glue applied to the sheets in lines with a pitch of 25 … 35 mm.

If the irregularities are up to 40 mm, then the plasterboard sheets are laid in two layers.

The first layer is made of sheets cut into strips up to 10 cm wide. The second layer is assembled from solid sheets and fixed with putty.

Of the tools needed to complete the work, you cannot do without a tape measure, a sharp knife, a level, a jigsaw, a rubber hammer.

You will need putty, grout, masking net and tape.

For fixing drywall sheets, it is recommended to use special adhesives.

Frame method of fastening the gypsum board

Installing the frame is necessary with high unevenness of the walls and on wooden surfaces.

The frame method of wall cladding with drywall sheets provides for the installation of a frame designed for leveling surfaces and fixing drywall sheets.

Frames can be assembled from wooden beams or galvanized metal profiles.

For the construction of a wooden frame, it is recommended to use a bar with a cross section of at least 30 × 30 mm, carefully treated with antifungal, fire-fighting compounds. From the compositions, we can recommend the liquids Aquatex, Senezh, Drevoteks. When assembling a frame from a wooden bar, be sure to leave gaps at the top and bottom for air circulation.

The bars are fastened to the wall with dowel-nails. A self-adhesive backing is placed under the bars.

A frame made of timber is advisable to use in wooden rooms. This will allow you to get an absolutely ecologically clean room.

It is more expedient to use structures mounted from galvanized metal profiles such as CD or UD as frames.

CD profiles are designed to act as carriers, and UD profiles are guides.

With the help of UD profiles, the flatness of the surface is set, and the CD-type profiles allow you to create volumetric structures and create rigidity for the structure.

For plasterboard wall cladding with your own hands, it is necessary to perform a number of mandatory works.

The preparatory stage includes cleaning the wall from dust, dirt, old paint and wallpaper.

Marking is applied to the wall using a building level.

The bearing profile is attached to the marked lines with self-tapping screws or dowels.

First of all, you should fix the extreme vertical guides. Pulling a thread between the extreme guides, a painting cord or fishing line fix the remaining guides, while maintaining the flatness of the surface.

Having fixed the bearing, proceed to the installation of the profiles reinforcing the frame. It must be remembered that the reinforcing and leveling profiles serve as the basis to which the plasterboard sheet is attached.

U-shaped brackets should be used to stiffen the structure. By the way, the U-shaped brackets must be fastened in the middle along the marked markings.

When assembling the frame, keep in mind the flatness of the surface.

Vertical bearing rails are fixed at a distance of 400… 600 mm. Their length is equal to the height of the wall.

Plasterboard sheets are attached to the frame with self-tapping screws strictly at right angles. The screw cap must be recessed 1 mm. The step of fixing the sheets with self-tapping screws is 25 cm.

First of all, the sheets are mounted on the wall without openings.
