To date, the use of plasterboard sheets in the implementation of repairs in a cottage, country house or apartment is the right and economical solution. By means of the above-mentioned building material, it is possible to remove without any difficulty all the defects of the uneven surface, having obtained an even base for subsequent finishing. In order to understand how to properly fix the drywall to the ceiling, you will need to identify the features of this raw material and master the installation options.
The gypsum plasterboard includes gypsum filler with various bonding agents and facing layers of cardboard. The weight of one sheet ranges from 12 to 35 kg, depending on its thickness: 6 mm, 9 mm and 12.5 mm.
Extensive use of the presented material is due to several important advantages:
Preparatory work is an important step in any construction activity and determines the entire course of further installation. They include:
Proper marking of the positions of the guide elements is the key to the success of subsequent installation. It is worth remembering that the procedure described above provides for a leveling floor!
The ceiling in a wooden house can be easily sheathed by plasterboard plates This finish not only has an aesthetic appearance, but also provides a natural indoor climate.
Currently, the following types of plasterboard fasteners to a wooden ceiling surface are used:
Installation of gypsum boards without a profile involves the use of special adhesives and the presence of a perfectly flat glued surface. In most cases, gypsum mastic is used as a bonding mass, which includes bone glue and crumb stone. The application of the mixture should start from the edges of the sheet in small cakes with an interval of 30 cm from each other, gradually moving towards the center. After which the plate is pressed on the prepared surface. To increase the adhesion properties, it is useful to prime the ceiling in advance.
Since gypsum sheets have a considerable weight, in the wooden ceiling finish version, to reduce the generated pressure, the slab can be divided into two equal parts, which will greatly simplify the installation procedure and the material will snap faster.
The presented design allows you to “hide” all the defects of the ceiling, greatly saving its height. Rack frame is advisable to use in the construction of single-level surfaces. The main advantage of this method is its low cost. However, its arrangement requires a well-dried timber, otherwise the supporting elements will soon be covered with mold and deformed.
Over the entire plane of the ceiling we place the main timber in 80 cm increments. Then, relative to it at an angle of 90 °, we fasten the partition walls 50 cm apart from each other, which will then become a retaining basis for drywall.
Having finished the installation of the frame, we proceed to the fastening of the plates. Screws are screwed around the perimeter of the sheet with an interval of 15 cm in a checkerboard pattern so that the rod head is slightly buried in the material. Subsequently, these places are puttied, and the entire surface acquires a smooth appearance.
When installing drywall, leave a distance between joints of about 5-7 mm. Subsequently, these gaps are easily filled with putty, providing better grip throughout the plane.
The procedure for assembling the structure is approximately the same as in the arrangement of the wooden frame, however, there are a number of nuances. The guide profiles are attached in 40 cm steps, so that one classic plate with a length of 120 cm is fixed on four such metal rails.
Having finished with the arrangement of the guide bases, proceed to fixing the suspension devices. Attach them to the ceiling with dowel-nails at a distance of 40 cm from each other. Next, the carrier profile is fastened, so that its ends are strictly on the guide rail at an angle of 90 °, and the body is in suspensions. Fastening of all elements of the frame with each other is carried out by special screws on the metal.
In the course of performing all installation work, the horizontal position of the profiles must be checked by level, and the places of the intended load must be strengthened by bridges or anchor fasteners.
The procedure for installing plasterboard sheets involves the use of two pairs of hands, however, to sheathe the ceiling alone you will need to use additional holding devices. One of such self-made devices are the platform and props.
This option involves making a small construction from a pair of boards, hinges, and supports. When opened, the height of the sliding platform should be 5-6 cm below the ceiling.
When manufacturing, do not forget to take into account that, along with the construction, the width of the gypsum board is included in this gap.
The process of lifting the plate is carried out in several stages. First, the first selection is put up to the height of the hand, then the main one. After this, we climb onto the prepared forests and quietly fasten the drywall to the frame.
In conclusion, I would like to note that fixing plasterboard sheets to an equipped frame is the most reliable option for finishing, rather than using adhesives, especially in a wooden house. Due to the fact that buildings made of wood "live their lives" and are constantly in motion, then no one knows how a glue base can behave after some time.
