Having their own home, almost everyone is faced with the problem of aligning the walls. Someone wants to change the layout by installing additional walls, while someone wants to make arched doorways. All these desires can be realized using frame installation of gypsum plasterboards.
Methods for installing gypsum plasterboards
Drywall is an easy-to-work material: it is easy to install, easy to cut, and flexible when bent. Depending on the evenness of the existing walls, you can glue drywall to the wall or mount it on a frame. Glue plasterboard plates on the plane of that wall, the slope from the level of which does not exceed 1 cm by 1.5-2 m.
The frame installation method is used when leveling very curved walls. Moreover, the curvature of the walls can be both horizontally and vertically. You can create a frame from wood or metal. Thanks to the use of the frame, arched openings, niches, slopes of windows and doors are arranged. It is possible to build different shelves and mezzanines made of plasterboard in the house. There are a lot of options. It all depends on the skill of the chosen master and on the design habits of the owner of the apartment.
The choice of material for the frame
A drywall frame is used when you need to level the walls. This method is good in that it is possible to hide the wiring and communications behind the frame. The frame makes it possible to insulate the room using mineral wool or foam. Under the drywall, a frame is built from wooden slats or metal profiles.
Wooden slats must be treated with a special anti-fungal compound. The timber frame is used in dry rooms. The slats must be well dried and free from knots. This prevents the entire structure from distorting during drying. The presence of knots leads to breakage. The rail to be installed must be complete along its entire length. The best choice is a 3/5 cm rail. Moreover, the 5 cm side is the front side. Drywall is attached to it. In the frame version, it is very important to build the frame correctly. After all, plasterboard plates are attached to it. For the metal frame, special factory-made profiles are used. You should choose a harder profile. They are available in 2, 2.5 and 3 meters in length. Its size is 3/6 cm.
Basically, the installation of wood and metal frames is the same. The initial stage in the device of the wireframe mesh on the wall is the marking of the processed plane. Taking into account the dimensions of the drywall in width (1.2 m), the wall is marked into even 0.6 m sections. The first horizontal line is drawn in the corner of the wall. All subsequent lines are marked from it at the specified distance. The line is drawn from ceiling to floor. Marks are made along the lines using a level to fix the suspensions. The distance between the hangers is 0.5 m. The profile guides (rails) are attached to these hangers with self-tapping screws for metal or wood. The hangers themselves are attached to the wall. If the initial wall is wooden, use wood screws. In the case of a concrete or brick wall, dowels are used. A very important point is the fastening of the hangers to the wall. Whatever one may say, the wall of the house is the base to which the entire frame structure is attached. Therefore, you should fix the suspensions with high quality. If the screw or dowel does not hold in the wall, you need to move it slightly up or down. In no case should the suspension be shifted to the right – to the left, this will cause the profile installation level to be lost..
In each of the corners, they are installed along the profile. It is required to install by level. It’s better for two people to mount a profile. After all, it is very difficult for one person to fix the profile, while adhering to evenness. For an even installation is required in two planes: relative to the processed and adjacent walls. The profile is attached to the suspensions only to the lateral (narrow) plane of the profile itself.
Above and below, the nylon thread is thoroughly pulled. It should be pulled in such a way that it runs along the wall, touching the two installed profiles. All the remaining profiles are mounted along these threads. When fixing them to suspensions, it is unnecessary to forget about maintaining the evenness of two planes. It happens that the profile (rail) is installed correctly along the threads, but the middle part of the profile has a deflection inward or outward – this is a curved wall.
Securing drywall sheets
It is also important to remember that the plasterboard is flat with right angles. If the profile is shifted to the left or right, then the installation of drywall may become more difficult. After all, each sheet of drywall captures half of the plane (3 cm) on the profile. It is worth rejecting one sheet from the level and all the others will follow. In addition, the possibility of normal fixing of drywall sheets is lost. Drywall is a brittle material, therefore, a 3 cm grip is made for fixing. Less grip leads to breakage of a piece of the sheet, subsequently the sheet will come off.
If the height of the plasterboard sheet is not enough to cover the plane of the wall, it is necessary to use transverse pieces of profiles. They are fixed between existing horizontal profiles. For example: a drywall sheet is 3 m high and a wall is 4 m high. Drywall is fixed from below, on it a piece of sheet of the missing height. At the junction of these pieces, a transverse profile is screwed on. Its length should correspond to the distance between the profiles, plus 6 cm (3 cm of grip for each profile). The vertical profile is installed so that both sheets of drywall grab it evenly.
It is important when installing sheets to install them in a checkerboard pattern. If the first sheet is fixed from the floor, then a meter piece is fixed next to it. A whole sheet of drywall is installed on it. The drywall is fixed with self-tapping screws 25 mm long. A screwdriver with a special nozzle is used to tighten the self-tapping screws. This nozzle has a limiter so as not to fall through the drywall. If someone decided to do the installation of drywall with their own hands, then they should not be afraid of this process. There is nothing complicated about it.
