Quite often, recently, owners of apartments, offices and premises for various purposes, undertaking repairs, have resorted to redevelopment. This allows you to use the space more ergonomically, while the old walls can be dismantled, erecting new partitions, using modern materials.
The most common in recent years is the installation of drywall partitions. This technology requires a minimum amount of money, effort and time. Building materials are fairly lightweight, which means they are an excellent alternative to foam blocks and bricks, and the optimal combination of quality and price should be taken into account. Plasterboard sheets can attract the simplicity of the device partitions from them, which requires a minimum set of tools and additional materials.
Reviews of drywall partitions
If you decide to build a plasterboard partition with your own hands, reviews about such designs should definitely be read. They can be both positive and negative. Among the advantages, consumers distinguish:
- high speed of construction;
- minimization of wet processes;
- the ability to choose fireproof material;
- soundproofing;
- the possibility of introducing water and electrical wiring into the cavity;
- insignificant weight of partitions;
- the safety of drywall.
According to home masters, the speed of construction at altitude. The sheets have solid dimensions, and the partition can be erected in one or several days. Before you start installing drywall partitions, technology and reviews need to be studied. After reviewing the latter, you can find out that wet finishing processes are either completely excluded or minimal. You will not have to work with the solution, and gypsum plaster will not leave much dirt in the house. But dust is still inevitable. According to experts, it will form when cutting drywall. Doors and windows in the process of such work is best kept closed.
If the requirements for fire safety are high, you can choose a fire-resistant material. But even if drywall does not have this purpose, then the composition of the paintings is a material that does not burn and has poor thermal conductivity.
Negative reviews
In addition to the positive features, consumers sometimes still note flaws. They are expressed in low mechanical strength of the partitions, as well as in poor resistance to water. A sheet of drywall can be broken simply enough, leaning on it with all the weight.
The consumer notes that GCR can be deformed when exposed to a massive object. You must be prepared for low water resistance. Even if you get moisture-resistant drywall, with prolonged contact with the liquid, it can become unusable.
Recommendations for choosing the type of drywall. Preparation of additional items
Before you start installing a drywall partition, you need to figure out what this material is. And this is a three-layer sheet of gypsum, which is pasted over with thick paper. The width of the sheets is 1,200 mm, while their length can be equal to the limit of 2,000 to 3,000 mm. You can select the width in the range from 6 to 12.5 mm.
Depending on what the purpose of the room is, you should choose the option of drywall, namely:
- moisture resistant;
- normal;
- refractory;
- with combined characteristics of fire resistance and fire resistance.
As for the guide profiles, they can have the following dimensions: 50 x 40; 100 x 40 or 75 x 40 mm. The constant is the length, it is 3 m.
In order to find out how many profiles are needed to carry out the work, the perimeter of the partition should be divided by 3 and rounded up to an integer value. If the partition will include a double frame, then the number obtained in the calculation should be doubled.
When installing a drywall partition, you will need rack profiles that differ from the above shelves on top. They create extra rigidity. The number of these elements depends on which installation technology is selected. Profiles can be angled, they will also be needed for installation work.
For quick installation, you must purchase dowels. They are used for mounting rails. These elements can be replaced with black screws, if work is being done in a wooden house. 25 mm self-tapping screws will be needed to fasten the sheets to the metal frame. They sometimes fasten wall profiles and guides. It will be possible to strengthen the design with wooden bars, which are located in the places of the doors.
Set of tools
When installing a drywall partition, you must prepare:
- hammer drill;
- drill;
- plumb line;
- level;
- screwdriver;
- nozzle for screws;
- scissors for metal;
- hammer;
- knife;
- pencil;
- roulette.
If you want to complete the work in a short time, then you can not do without a punch. The presence of this tool is necessary if you have to work with reinforced concrete floors and walls. When manipulations are carried out in a prefabricated house or a building made of monolithic reinforced concrete, a reliable and powerful perforator for domestic use should be prepared. You can replace this tool with a drill if installation is carried out in a wooden house.
Before you start installing partitions from the GCR, step-by-step instructions should be studied. Having familiarized yourself with it, you can find out that you will also need a plumb line. With it, you can achieve high quality work. You may need a laser plummet, a modification of which involves the presence of beams that simplify the work. With two long levels you can replace the plumb line. But the accuracy may decrease.
The process of screwing sheets to the profile frame will be pleasant and quick if you have a screwdriver in stock. If you have not got this tool yet, you can use a drill, having bought necessary nozzles to it. To cut the metal elements of the frame in accordance with the size of the partition should be prepared scissors for metal. This tool is still being replaced by a machine or grinder, if one of them is available. For one-time use, it is unprofitable to acquire such devices.
Technology of work
Installation of interior partitions from drywall begins with a markup. In the process, you will need to determine the location of the guide profiles. Next, you can install rack profiles. The next step is the sheathing of the frame sheets.
Start marking should be from the floor. On its surface with a pencil or marker, it is necessary to mark the faces of the structure. 1.2 cm should be retreated from the marked lines inward, which will be the thickness of the drywall sheet. This is true if the skin will consist of one layer.
New lines along which guide profiles will be laid out are drawn in the next step. Marks can be moved to the ceiling surface using a plumb line. This markup allows you to set a guide profile.
Mounting the guide profile
In accordance with the size of the partition, it is necessary to cut the profile. Its fastening begins from the floor, passing after to the ceiling. Do not forget about the use of sealing self-adhesive tape. It is located at the junction of the profile to the mating surface. This will ensure soundproofing of the structure. The profile is fastened to the surface with dowels. The distance between the elements will be 1 m.
Installation of vertical profiles
The installation of interior partitions from drywall at the next stage involves the installation of rack profiles. The metal profile should be located at the openings and at the joints of the sheets. One profile is fixed in the center between the docking elements. They should be removed from each other by a sheet width, which will be 1.2 m. You will get a grid with a distance between the elements of 0.6 m.
In order to increase the strength of the frame, it is necessary to reduce the distance between the vertical profiles, which will be 0.4 m. But this will be associated with additional costs, because the number of profiles used will increase by 1.5 times. In order to strengthen the profile, you should use wooden blocks. Their cross section can be 40 x 50 or 40 x 40 mm. Especially important are these manipulations at the locations of doorways. This will avoid difficulties in installing doors. If the door is not provided for in the project, reinforcement may not be necessary.
Gypsum plasterboard casing
The technology of the device of drywall partitions at the next stage provides for the fastening of sheets. For vertical profiles, for convenience, the central parts of the elements must be marked on the ceiling and floor. Work begins with solid sheets. Then you can start cutting pieces using a knife, tape measure and the rest of the profile. According to the latter, it is convenient to cut the cardboard. After that, the sheet is taken for kink and cardboard is cut from the second side. If the incision is uneven, it can be calibrated with a planer or knife.
Sheets are fixed to the metal profile with self-tapping screws, the distance between them should be 200 mm. The device of drywall partitions with the hands at the next stage provides for finishing work. First, the seams are putty, as well as those places where the screws are located. If necessary, it is possible to carry out surface treatment with putty. Work should be completed with a fine finish.
Installation of the partition in the Knauf system
At the first stage, the line on the floor must be marked with a painting cord. At the next, using a laser level or plumb mark is transferred to the ceiling and adjacent walls. The installation of drywall partitions according to the Knauf system at the next stage involves the installation of a frame from a profile. To the ceiling and floor should be strengthened PN. It is necessary to use dowels, between which a distance of 80 cm is maintained.
The overlapping of the profile fastening is carried out together with the laying of the sealing material. Next, install the rack profile. The distance between these elements should be more than 600 mm. In the frame structure, shelves, supports for cabinets, as well as lamps are installed. All necessary communications and wiring are laid inside.
Now you can do the facing of the frame. On the one hand, sheets are strengthened with screws. The distance between them is maintained within 250 mm. Next, the sound insulation is laid between the racks. The material should be as tight as possible. Next, a full lining is made. To do this, the sheets are mounted on the second side of the frame. If the type of partition will provide for a multilayer coating, then each layer should be installed with an offset of 600 mm from the previous one. The lining of the frame is finished. Between the sheets should be putty seams, as well as fill the solution with holes from the fasteners. Drywall is primed for decorative finishes.
Cost of work
You can independently engage in the construction of a drywall partition, the price per m2 at the same time, however, may interest you. For example, for work when the frame will consist of racks and a transverse profile located at the edges of 2 sheets, you will have to pay 790 rubles. The distance between the racks will be 60 cm.
If the step between the racks is reduced to 40 cm, then you will have to pay 1,010 rubles for work with the material. The design will provide for the presence of soundproofing and finishing the frame with one sheet of drywall from 2 sides. The estimate for the drywall partition may include the installation of 2 sheets of drywall and sound insulation. The step of the metal rack remains, as in the previous version, while a distance of 50 cm will be maintained between the transverse columns. For this, you will have to pay about 1,210 rubles. Which is 530 rubles. per square meter - the price of work, and 680 rubles. per square meter - the price of materials.
The prices for the installation of the drywall partition will be different if the design will include niches, as well as external corners. For a running meter you will pay about 610 rubles. The price for the work will be 330 rubles. per square meter. For materials, you will have to pay 280 rubles. per square meter. If specialists are engaged in the construction of drywall partitions, they usually indicate the prices in the estimate separately. For example, in the list you can see the price for installing interior doors in such partitions. If the design will include extensions and platbands, then for the installation of the door you will have to pay 1,850 rubles.
Partition opening
Initially, it is necessary to determine where the opening will be located. After that, on the floor along the intended contour, it is necessary to lay a metal profile, which is fixed with screws or dowels. The profile should not be laid to the full length, but only to the place of the doorway. If you plan to place the door against the wall, you should place a solid profile on the floor to the opening. But when the opening is located in the center or close to it, the profile consists of two segments and will be located on different sides of the opening.
When arranging an opening in a drywall partition, determine the location of the profile on the ceiling. The easiest option would be to use a laser level. With it, you can mark the line on the ceiling. If there is no such tool, you can use the plumb line that descends from the ceiling. The upper profile is fastened with self-tapping screws and dowels. The distance between them must be maintained in the range from 50 to 60 cm.
Each wall should be installed vertical racks, which are fixed to the wall surfaces with screws. In order to increase the sound insulation of the structure, together with the profiles that are strengthened to the building elements, a sealing tape is laid. Next, install two racks that will determine the opening. They are attached to profiles that are located on the ceiling and floor. Intermediate racks should be installed from each wall. Now you should cut a small piece of profile, the length of which will be the width of the doorway. 2 racks of 10 cm should be added to this value. The letter P is formed from this segment, which is attached at the location of the horizontal crossbar.
In order for the element to be durable, a rack should be installed. Its size is determined by the distance from the cross member to the ceiling profile. You will need to create a frame above the opening. The system is fastened with self-tapping screws. To make the rack stiff, a wooden beam is inserted in the doorway. In this case, the price of work will increase. Such an aperture will have high strength. On sale, however, you can find reinforced models that can withstand heavy loads.
Finally
Now you know how to make a gypsum interior partition. It will allow you to divide the room into two, which is especially important when the family has heterosexual children. When installing a capital wall of brick, permission will be required in the relevant instances, and such work is quite expensive. It will be cheaper to build a plasterboard partition. In addition, if necessary, you can dismantle it over time.
