Surface under drywall. Fastening drywall to the ceiling and walls

If the walls or ceiling need to be leveled, then, as a rule, plasterboard is used. However, its installation is not carried out to the wall itself, but to the frame system. In order to learn how to level the surface of the room, it is necessary to get acquainted with the technology of carrying out the works on installing the lath. Such work begins with the measurement of the area and the acquisition of high-quality material. The cladding can be made of wood or metal. The latter option is more preferable and durable.

Installation of metal frame

Metal crate under gypsum board is characterized by a long service life. This quality is one of the advantages. The surface will be smooth, so additional processing is not required, which can not be said about wood. To mount a steel frame, you need to prepare a profile, as well as a specific set of tools. Here are the main ones:

• a hammer;
• Screwdriver;
• Installation level;
• Drawing pencil;
• Punch or drill.

Visiting the store, you can be sure that the metal profiles can be divided into three types. Select one of them, depending on the plasterboard structure. For example, when finishing the ceiling, you should use the PP profile under the gypsum board, which looks like a C-shaped product. The stand profile is indicated by two letters - PS and has a stiffening rib. With its help, you can fix the points of the structure. Use these products also to create partitions. Guide profiles are denoted by the letters PN, they are U-shaped and are used for fixing wall and ceiling structures.

For reference

Girders under the plasterboard require the use of additional components. With their help you can ensure reliable fixation of the plates. Such elements include brackets, dowels and screws.

Mounting the grid on the wall

Before the manufacture of the lath, it is necessary to make a marking in the place where the installation is planned. Leaving the wall 6 cm, on the surface of the ceiling you need to draw a straight line. This label will allow you to set the guide profile. The line is transferred to the floor. Such work can be done quickly and comfortably with a laser level. The landmark will be the line marked on the floor. As soon as the labels are applied to the work surfaces, you can start installing the crate. For this, a perforator is used to fix the guide profile to the walls. After that, the assembly and further installation of the posts, on which the sheets of plasterboard will be fixed, will be carried out.

Work on the crate ceiling

The gypsum plaster board on the ceiling should have racks that are made of PP and PN profiles. First, the markup is done. To do this, on the surface of the wall with a ledge at 14 cm from the ceiling, you need to make a mark, this distance will be required for the installation of communications. The lines are fixed PN. In those places where the bearing profiles are located, suspensions must be installed. The optimal distance between them should be 50 cm. The guide rails should be cut off and the PN profiles must be installed. Fastening elements will allow to fix cross-section profiles on the frame system.

Installation of wood battens

Wooden crate under the plasterboard can be installed in rooms with a normal level of humidity. For this, wooden beams are used. In addition to these, you will need the following tools:

• Electric jig saw;
• Screwdriver;
• Mallet;
• a hammer;
• roulette;
• saw;
• hammer drill;
• chisel;
• level;
• Building corner.

As a material, a bar will protrude, from which the crate will be installed. For the substrates you need a board, but the beams to the base will be attached using dowels and screws. First places for mounting the outer frame elements are marked. This is especially important if only a certain part of the surface is occupied by the finish. Planks or bars, located along the perimeter, should be measured with the help of plumb bows and level, as the subsequent elements will be guided by this frame.

If there are irregularities on the surface, then under some bars or only their parts, it is necessary to lay the material. Then the external boundaries will allow to form a whole plane. Sometimes the bars are undermined. The choice of the surface leveling option will depend on the nature of the irregularities. If they are on the entire surface of the floor or wall, it is best to use substrates. If the unevenness needs to be corrected only at some distance, then the highest point should be determined and the position of the frames of the frame system should be calculated from it.

When the crate for plasterboard is being arranged, it is necessary to take a margin in the range from 2 to 3 mm on the unevenness of the beams that will be used for the frame. As soon as you determine the direction of the first beam and calculate the size of the substrates, you must fasten the element with screws and dowels, the first being installed at a distance of 25 cm from each other. Once the first bar is on the wall, you can proceed to install the rest. With their help, it will be possible to form the perimeter of the crate. It is important to try to bring the common plane through the level. If the room has window and door openings, then the projecting parts should be supplemented along the perimeter with a bar to fix the edges of the element along the border.

Methods of work

When the crate under the plasterboard is performed, the next step is to proceed with the installation of the cross bars. In their rigid connection, there is no need, this is especially true in the event that you are not sure that the wood is normally dried. When using substrates, the edge of the beam should be fixed, it is important to check with the level and plumb readings, only after the fastening in the center begins. Wood should be treated with a protective composition with flame retardants and antiseptics, this will eliminate the rotting of the material, as well as the formation and development of the fungus.

Installation of plasterboard on the frame of walls and ceiling

When the crate under the gypsum cardboard on the wall or ceiling is ready, you can proceed to install the sheets themselves. For this purpose, 35 mm screws are used, which are made of black iron. It is recommended to screw them with a screwdriver so that the cap is recessed into the sheet. Place the fasteners at a distance of 15 cm from each other, screw in the central part of the sheet too.

On sale you can find GKL, which have a central line. This facilitates the installation process. Now you know how to make a crate under gypsum board, but it's also important to get acquainted with the rules for installing sheets on the frame. If there are gaps on the surface that do not include a whole sheet, elements of suitable size are cut from the pieces. To do this, use a construction knife.

Sizes and costs

The size of plasterboard and the price are the two factors that are most important for the consumer. Thus, gipsokartonnye sheets, the size of which is 2500x1200x15 mm, will cost the consumer 315 rubles. a piece. The cost can also affect the manufacturer. In the first case, it was about the company Gyproc "Strong", whereas if you buy a sheet with dimensions of 1200x600x20 mm from the manufacturer Knauf, then one sheet will cost you 320 rubles. The size of the drywall and the price will allow you to calculate the required amount of material for the work, as well as determine the cost of repairs.

Conclusion

When the profile for drywall, like all components, as well as tools will be prepared, it is necessary to enlist the help of a partner. It should be remembered that the sheets have enough overall dimensions, so cutting them alone will be inconvenient.
