Used indoors for various purposes, both during reconstruction and in new construction with the aim of:

• finishing;
• solving design and planning problems;
• eliminating uneven floors;
• hidden placement engineering communications;
• increasing the sound insulation of floors;
• acoustics;
• increasing the fire resistance of floors and coatings.

Installation process

The installation process includes the following stages of work:

• marking the design position of the suspended ceiling frame;
• assembly and fastening of the frame;
• installation of KNAUF plasterboard sheets (GKL) in the design position and fastening to the frame;
• sealing seams between KNAUF plasterboard sheets and, if necessary, continuous puttying of the surface of the suspended ceiling;
• priming the surface of a suspended ceiling before applying paint or decorative coating.

Installation of suspended ceilings should be carried out during the finishing work (in winter time when the heating is connected), until the installation of clean floors, when all “wet” processes are completed and the wiring of electrical and plumbing systems, under dry and normal humidity conditions in accordance with SP 50.13330.2012 Thermal protection buildings. Updated version of SNiP 02/23/2003. In this case, the room temperature should not be lower than 10°C.

In conditions high humidity(bathrooms, kitchens) it is recommended to use moisture-resistant KNAUF plasterboard sheets (GKLV).

Location electrical wiring in the space of the ceiling frame should exclude the possibility of damage by sharp edges of frame elements or screws during fastening of plasterboard sheets.

Advantages

• The complete P 112 system allows you to most correctly, efficiently and economically solve a specific construction problem - creating a suspended ceiling.
• In the process of creating a suspended ceiling, inconvenient “wet” processes are eliminated.
• Labor productivity increases significantly.
• Overall savings in construction costs are achieved by lightening the building structure.
• Provides the opportunity to implement unlimited in design, multi-variant architectural solutions ceilings.
• The finished ceiling has high level quality of finished surfaces.
• The surface of suspended ceilings P 112 is suitable for any finishing: painting, wallpapering, decorative plastering.
• The heat and sound insulation qualities of the room are improved.
• Not only environmental cleanliness is ensured, but also a microclimate in the room that is favorable for humans. Since the main material of the complete system - KNAUF plasterboard sheet - has the ability to breathe, that is, absorb excess moisture and release it into environment in case of shortage.

Let's look at the Tigi-Knauf ceilings. This technology was first proposed by the German company Tigi-Knauf; they became very popular and are called by the name of this company. In Russia, they are widely used in industrial and office construction, as well as in the decoration of residential premises. The comparative cheapness, speed and relative ease of installation have made the Knauf suspended ceiling in demand in our market.

Advantages

Such a ceiling in combination with sound and thermal insulation materials gives optimal performance.

The Tiki Knauf suspended ceiling kit includes sheets of certain sizes made of plasterboard and a special metal frame.

Conditions for installation

It is recommended to begin installation of suspended ceilings made of gypsum plasterboard during finishing work, but always after completion of the main work associated with the wet process. All wall leveling work must also be completed. If the walls are sheathed with plasterboard, they must be sheathed by this point, if provided plastering work, then must be plastered.

Installation must be carried out under the condition that dry or normal humidity conditions are maintained in accordance with SNiP 23-02-2003 “Thermal protection of buildings”. The temperature in the room where work is carried out and where installation materials are stored should not fall below 10°C.

Before starting installation, perform an accurate calculation future design, mark the construction of the grid in accordance with the recommended step for a given type of ceiling and mark the fastening of the suspensions to the base ceiling in accordance with the type of load (see)

Advice. All electrical, ventilation and other communications, if they pass above the suspended ceiling, must be installed and their functionality must be checked.

Preparing for the installation process

What tools do we need in order to assemble suspended ceilings with high quality? Let's prepare the following set of tools:

• hammer drill
• screwdriver

Advice. Screwdrivers are best used with batteries. It's more convenient and safer.

• metal scissors

Important. For large volumes, you can use a grinder with a metal circle.

• paint pad with paint
• roulette
• rule with level
• laser or water level.
• knife for cutting drywall sheets
• special plane for processing sheet edges

Despite the impressive list of professional construction tools, complete KNAUF systems are installed quite simply, of course, if the master has an idea of ​​how to use these tools and carefully studies the technology of ceiling construction.

Ceiling markings

• We will need a water level or a laser level and a lace - a paint tap. From the lowest point of the ceiling or technical protrusions on it, we will use a cord to mark the level along the entire perimeter of the walls.

Advice. What is the beating used for? If you use a water level or a laser level, then simply mark the corners, and then connect them using a tap.

• Next, we decide at what height we want to get the finished ceiling. You must understand that from the broken level the entire system will drop by the width of the profile plus the thickness of the sheet or, if desired, two sheets of drywall, that is, by 4-5 cm.

Advice. Pay attention to the location of all electrical and other process wiring in the space above the ceiling frame. Any possibility of accidental damage by their sharp edges must be excluded. metal frame or with screws when attaching plasterboard sheets.

Installation of the sheathing frame

• We proceed to fastening along the entire marked perimeter of the 28X27 guide profiles using any type of fastener that is suitable for your walls.
• We mount ceiling profile Knauf 27X60. The recommended profile fastening step is 40 cm.
  • To connect individual sections of the profile, which are installed at an angle of 90 degrees relative to each other, use a single-level connecting profile, otherwise known as a “crab”. This element received this name due to the similarity of its shape to the shape of a real crab.

Having installed it at the junction, special fasteners are secured in the profile cavity, and the fastening itself should snap into place.

• The “crab” is screwed to the guides using self-tapping screws (LN) sized 3.5x9.5 mm, which also received their diminutive names from the builders: “bugs” or “fleas”.

As a result, we should get a sheathing from a profile with a cell of 40X40.

• Then we outline the places for installing the hangers. Using dowel nails, we attach the hangers to concrete floor ceiling. If the ceiling is made of something different, more soft material, then the hangers can be secured with screws.
• By changing the length of the fixed hangers, we adjust the plane of our entire structure to one level. The ceiling frame is ready.
• We proceed to covering the frame with gypsum board sheets. The sheets should be fastened from the middle to the edges or from edge to other edge. We use self-tapping screws (TN) with dimensions f3.5x25mm. Screws are screwed in strictly perpendicular to the sheets and deepened into the profile by 10 mm, no less. And the heads of the screws should be recessed into the plasterboard by 1 mm.

Sheathing with plasterboard sheets

Advice. When starting to finish the mounted plasterboard ceiling, check whether the screws protrude above the surface of the sheet.

• The edge of the gypsum board sheet should fall on the profile, overlapping it by three centimeters. The joints of the end edges of the plasterboard sheets should be spaced apart, offset relative to each other by at least a profile step (40 cm).
  

  Advice. First, the end edges of the sheets are chamfered at an angle of 22.5° to a depth of 2/3 of the sheet thickness using a special edge plane.

• Using a narrow spatula, apply the first layer of gypsum putty inside the joint. Spread the excess mixture evenly over the heat-affected surface of the sheet. Next, reinforcing tape (serpyanka) is applied to this seam using putty; it should cover the width of the entire seam by at least 100 mm on both sides.
• The tape should be pressed into the layer of putty that has not yet hardened in all places besides the very deepening of the joint. There should be no waves or bends. After fixing the reinforcing material, you must wait until the putty has completely dried.

Sealing joints

• When the first layer has dried, take a wide spatula and first dry clean the surface of the seam from particles of putty and its frozen drips. Next, apply a thin layer of putty with a wide spatula, but this time covering large area leaf.

Advice: It is recommended to use a 250 mm spatula, in this case the layer will be of this width. The task is to smooth out as much as possible that invisible bump that appeared when applying the reinforcing tape.

• It is possible that you will have to putty more than once until you get a smooth surface. Finally, sanding is carried out with regular fine sandpaper or a special mesh.

We looked at the simplest device. You can install such a ceiling in an apartment yourself. It is only necessary to follow the technological sequence of work.

During installation suspended ceiling The main wishes of the homeowner are to ensure that the structure is strong, durable and attractive, and that the installation work does not take much time. Plasterboard ceilings using Knauf technology meet all these requirements. Let's look at all the features of this technology in this article.

Briefly about Knauf technology

Knauf is a German development. Its developer is the Tigi-Knauf company, which produces high-quality materials for construction and repair - various sheets of drywall, fasteners, profiles, etc.

Knauf is a variant of manufacturing suspended structures using plasterboard sheets, which are attached to a special suspended frame.

What should the frame be like?

When assembling the frame for suspended structure, the company recommends meeting the following requirements:

1. Use sheets of plasterboard produced by it, which have high moisture resistance.
2. Installation of profiles in a checkerboard pattern with an overlap or out of order so that the ceiling does not deform under the weight of the plasterboard.
3. Connect profiles with fasteners manufactured by Knauf.
4. Avoid joining sheets in the center of the opening so that vibrations that occur when opening the door do not cause deformation of the coating.
5. After completing the installation of the frame, it should be finished using thermal insulation tape.

The ceiling frame is installed independently using Knauf technology using special profiles marked CD and UD.

Pros and cons of technology

The advantages of ceilings using Knauf technology include:

1. Small time costs for carrying out work. If you have all the necessary tools and sufficient qualifications of the craftsmen, installation can be completed in one day.
2. The possibility of installing such a ceiling in any room, regardless of size and configuration.
3. Ease of subsequent processing and it is possible to use any type of material.
4. Successful leveling of various defects in the base ceiling and hiding communication lines due to the presence of a gap between the coating and the surface to be finished.
5. Availability additional features in the form of laying a layer of material on the ceiling for insulation or sound insulation.
6. Availability of installation different variants designs. It can be single-level with the presence spotlights or multi-level.

The only disadvantage of the technology in question is that when installing such a ceiling, the height of the room is significantly reduced. But this is a minus only in the case of small rooms; for large rooms with high ceilings, this, on the contrary, can be an advantage.

Preparation for installation work

Work on installing the ceiling in question should be carried out during finishing work. In this case, all wet work must already be completed.

It is important to pre-level all vertical surfaces.

Creation is important for work room temperature and humidity. A room temperature below 10 degrees Celsius is not permissible for work.

What materials and tools will be needed?

Before you begin installing the ceiling, you need to prepare the following tools:

• perforator;
• cordless screwdriver;
• drill;
• roulette;
• pencil;
• a knife that can be used to process the ends;
• hydraulic level

A laser level would also be useful, since the frame assembled using the technology in question has a large number components, the location of which must be strictly level.

The materials you will need are drywall itself and frame elements - a metal profile or a wooden beam.

When making a frame from a metal profile, two types of guides will be needed:

• PN 27×28 - for installation around the perimeter of the room;
• PP 60×27 - for installation of other frame elements.

Types of drywall

In relation to operating conditions, Knauf plasterboard can be of the following types:

1. A - standard plasterboard for construction. Can be used when installed in a room that is heated and has low humidity (up to 60%).
2. H2 - has increased resistance to moisture. Can be used in a room with humidity up to 75% due to the low level of water absorption (up to 10%).
3. DF - flame resistant sheets.
4. DFH2 - combines the properties of DF type and H2 type plasterboard.

Basically, the frame calculation is carried out taking into account standard sizes plasterboard 1.2 × 2.5 m and thickness 9.5 mm. However, the dimensions of drywall may vary.

The edge of plasterboard is mostly semicircular and thinned, but some sheets have a different edge (straight, with a cut corner, thinned, rounded with a one-sided chamfer or semicircular).

However, the first type of lump is the most technologically advanced. Each of the other non-standard edge types are designed to solve specific structural problems. For example, to mount corner projections.

What types of ceiling structures are there?

Frame for stretch ceiling can be made using a Knauf metal profile or using wooden bars.

Suspended ceilings can be of 5 types:

1. P 111 - the biaxial frame is assembled from wooden beams.
2. P 112 - the biaxial frame is assembled from a metal profile.
3. P 112 - the assembly of a uniaxial frame is made from Knauf metal profiles.
4. P 131 - assembly of the frame using a light profile attached to the walls.
5. P 19 - architectural and decorative design with the creation of a complex multi-level ceiling.

Step-by-step advice from technology developers for those who want to do the work themselves.

More details:

1. Using a level for control and a tapping thread, you need to mark a line along the perimeter of the walls.
2. Taking into account the type of drywall that has been chosen, you should mark the guides with points for attaching hangers.
3. Using anchors or dowels, hangers are attached to the designated places.
4. Subsequent work depends on the type of frame that will be made - wooden or metal.
5. At wooden frame the beam is fixed to the base using a direct or quickly mounted (facilitates the possibility of instantly changing the fastening side) suspension. Next, the guide beam is fixed to the ceiling. To reduce differences in the height of the base, pads are used.
6. When installing a metal frame, the profiles are connected by hangers with a compensation gap of 10 mm provided so that it is protected during temperature changes. A sealing tape is placed under the guide profile. The profile used must be exclusively wall. Solid guides are attached to long wall. The dowels are fixed at a distance of up to 30 cm from each other. The supporting profile must fit into the guide by at least 3 cm.
7. After the frame is completely assembled, they proceed to covering it with Knauf plasterboard.

Fastening the guides

To mark a ceiling installed using Knauf technology, the usual building level will not be enough. It is recommended to use a hydraulic level or laser device. You will also need to purchase paint strips.

Having placed marks in the corners of the room using a hydraulic level, they are connected to each other using a cord.

The profile is attached under the intended line, and do not forget that the ceiling will drop by the width of the profile + a sheet of drywall. Therefore, you need to make calculations in advance so that the ceiling is not lowered too much.

On a note: When marking, you should determine the presence of electrical wiring on the walls and ceiling. The places where it is located are also marked so that the electrical wiring is not damaged during the installation of the profile.

After marking is completed, the guides, represented by a 27 by 28 mm profile, are secured. They are fixed to the wall using dowels 6 by 40 mm.

How is finishing done?

The main requirement for installing gypsum boards using Knauf technology is to fasten the sheets across the supporting profile. The screws must be screwed in at right angles. Previously, the edge of each sheet, not covered with cardboard, is processed to remove the chamfer.

The work is carried out with an assistant or a special one is used for this purpose. lifting mechanism. According to the rules, the sheets are secured in a checkerboard pattern or staggered. IN longitudinal direction The sheet must be laid without a gap; this will create a small gap in the transverse. This is the only way to achieve a perfect seam after the gap has been filled.

It is important to take into account the possibility of temperature changes affecting the finishing surface, under the influence of which it can expand and deform. If you provide special expansion joints in increments of 15 cm, serious deformation will be excluded.

The self-tapping screws need to be screwed in so that they are immersed into the coating sheet by about 1 mm, so their caps will not be visible on the surface. Reinforcing tape is used to seal joints.

Step-by-step implementation of final finishing

When designing and installing ceilings of the technology under consideration, which have two levels, it is necessary to make the material stronger by using finishing based on moisture-protective compounds and putty mixtures.

Seam masking is done as follows:

1. Using a narrow spatula, the joints are filled with putty mixture, the remains of which are removed.
2. Attaching seam tape.
3. Cover the tape with putty and remove the residue after 45 minutes or more.
4. Putty screw heads.
5. Repeated filling of the seams and removal of residues with a wide spatula.
6. Surface grinding.
7. Installation of an aluminum corner or PVC corner in the place of external corners.
8. Fastening between internal corner and gypsum board dividing tape. Coating the surface with putty.
9. Painting and plastering the material after it has completely dried.

Features of attaching drywall to the frame

More details:

1. Plasterboard sheets must be secured in the direction of all profiles using self-tapping screws. The latter should be placed at a distance from each other of no more than 20 cm. Where the sheets form joints, the screws are placed offset.
2. Trimming a straight part from this material can be done using sharp knife. After cutting the top layer, the sheet may be broken along the slot. If it is necessary to prepare shaped parts, it is better to cut them with a hacksaw.
3. Screwing in screws must be done carefully. The cap needs to be sunk a little into the material, but it should not be broken through with a self-tapping screw, because in this case the fastening will not be reliable.

Video on the topic

Knauf suspended ceilings are known to many people in the most different countries. They got their name from the name of their rather famous German manufacturer"Tigi-Knauf". Thanks to special production technology, Knauf complete suspended ceiling systems combine aesthetics, ergonomics and simplicity, coupled with a reasonable price. Knauf suspended ceilings are a subspecies plasterboard ceilings, therefore, they have some of its advantages and disadvantages. Many people install them at work or at home, and they are often used in industrial construction.

In our article we will look at the main thing, paying attention to the advantages of this type, its features, tips for, the installation process itself and the materials necessary for this. We remind you that carefully selected photos are presented specifically so that you can better understand the essence of the article, do not neglect to consider them.

Advantages of the Knauf ceiling

Plasterboard structures as such make it possible to adjust the height of the ceiling and hide communications underneath, since they can form multi-level structures at some distance from the base ceiling. Actually, this is why Knauf ceilings can be called suspended. But one of the most important advantages remains that with the help of sheets you can create structures of various shapes, including spherical and cone-shaped. The plasterboard also supports the insertion of lamps.

If you choose the right insulation, then such a ceiling will be indispensable and will serve you well. long service. In the kit you receive the drywall sheets themselves and a metal profile, which is necessary for installing the former.

Before starting work on installing gypsum boards - plasterboard sheets - it is necessary to complete all Finishing work, in particular, on the walls. Don't leave work that involves interacting with water until last. Naturally, before finishing the walls they must be smooth and clean, so take time for this too.

The installation itself must be carried out at a temperature of 10 degrees Celsius and above, and the best option will maintain an average temperature of 15-20 degrees. Therefore, as a last resort, when work takes place in winter, take care of heating for the room. This will help both people and materials stay in shape. Speaking about the humidity level, do not forget that dry mode is the most preferable, but normal mode is also acceptable. You can learn how the level of humidity is delineated from SNiP 02/23/2003 “Thermal protection of buildings”.

After meeting all the above conditions, it is necessary to accurately mark the ceiling, taking into account the pitch for the ceiling and the type of load for attaching the suspensions. That is, on the ceiling it is necessary to mark with a pencil the location of the sheets of drywall. Do not forget that those communications that you plan to hide under the ceiling must be carried out immediately after marking.

Required materials for installation and their types

When using manufacturer's sheets Knauf installation the ceiling should be carried out with the participation of 10, and sometimes more, different elements.

Let's see which ones:

Required amount of material for installation of gypsum boards

Ceiling by Knauf system usually quite heavy, because repairs involve a large number of elements (read also: " "). You could see this yourself by reading the previous subtitle. And it is very important to buy in advance required amount material so that it is enough for the entire duration of work. Our list of materials that are needed to secure gypsum boards on 1 square meter will help you with this.

Given average consumption materials that will be needed during the installation of the entire ceiling:

All of the materials listed are very important for the successful completion of the work. But do not forget that in this table we have not given the quantities of some other materials that will be needed only under certain conditions or on one section of the ceiling. Thus, these include fasteners, connectors, guide profiles and screws.

How to install a Knauf suspended ceiling, see details in the video:

Installation of Knauf suspended ceiling

Now we will look at the process of installing a Knauf suspended ceiling, which consists of many parts:

1. Preparing the necessary tools . Not a single builder can do without them, so take care of purchasing the missing ones in a timely manner. So, to install a Knauf ceiling we will need a hammer drill, a screwdriver (preferably with a battery), metal scissors or a grinder, a paint chip with paint, a tape measure, usually a level, a marking cord, a knife for cutting drywall sheets and a special plane for processing the edges of the sheet. Read the list carefully a couple of times so you don't accidentally miss it. important element. Do you have everything? If yes, then you can proceed to the next step.
2. Ceiling markings . A level and string will come in handy at this stage. It is necessary to mark a line along the entire perimeter of the room on the walls, corresponding in height to the lowest part of your ceiling. This can be done, for example, by marking 4 points on the walls on all sides using a level, and then connecting them with a cord. For the future, remember that from the marked line the finished ceiling will drop by 4 centimeters, no less. This will happen due to the installation of rather massive profiles and sheets. And do not forget that already installed communications should not interfere with work, otherwise they may be damaged by an incorrectly driven nail or acute angle profile.
   

   
   

3. Installation of the sheathing frame . First, according to the markings carried out at the very beginning, we fix the guide profiles with any in a reliable way. After this, a Knauf 60x27 ceiling profile is mounted in increments of about 40 cm. We connect the profiles that are at right angles to each other with a crab connecting element. Special clamps are secured in the profile cavity so that the fastening snaps into place. The crab is installed using LN self-tapping screws with dimensions of 3.5x9.5 mm. By the way, they are also called bugs or fleas. After this we get a high-quality sheathing with a cell of 40x40 cm.Next, according to the markings, we install the hangers and fix them on concrete surface ceiling using dowel nails. If the material on the base ceiling is softer than concrete, then it is permissible to replace the dowels with screws. When adjusting the length of the hangers, make sure that the entire structure is located on the same plane; check this with a level.
4. Covering the frame with sheets . For this step we will also need self-tapping screws, but different ones - TN with dimensions f3.5x25 mm. They are screwed strictly perpendicular to the sheets and must go deeper into the profile by at least 10 mm. On the other hand, the head of the screw should not go deeper into the surface by more than 1 mm. But under no circumstances should it protrude, so try to fix it in the optimal position - pressed in quite a bit.You need to screw in the screws either starting from the center to the corners or diagonally - from one corner to another. The sheets should overlap the profile by three millimeters, and the joints of the end edges relative to each other should be spaced apart and at a distance of no less than the profile pitch - 0.4 m. Before this, they often use an edge plane to chamfer at an angle of 22 and a half degrees and to a depth of two thirds of the sheet thickness.Next, a layer of gypsum putty is applied inside the joint using a narrow spatula. The excess should be spread over the sheet close to the joint. Serpyanka is glued over the sealed joint in such a way that the seam covers more than 100 mm on both sides. The surface of the film should be slightly pressed into the undried layer of putty, but at the same time it must remain perfectly flat, without irregularities or deflections.
   

   
   

5. Sealing seams . The final stage- this is putting the remaining part in order. Use a wide spatula to remove all drips and stains of putty that you find on the ceiling. Then they should apply putty on most sheet, as wide as is sufficient. Our goal is to level the mound of the reinforcing tape with the sheets as much as possible using putty. Therefore, it is not a fact that you will be able to cover everything from the first layer.

Thus, in this article we were able to examine in detail the suspended ceiling using the Knauf system and everything related to its installation (read also: " "). We hope these tips will help you renovate your home. the best way so that it serves you for a long time and is always pleasing to the eye!

Selecting a finishing option ceiling surface is one of the most important tasks that must be solved when performing repair work. Modern construction market offers quite a lot of materials with which the problem can be solved in several ways. Knauf technology for plasterboard ceilings can be considered as one of the options. About the most important principles for carrying out such work and we'll talk Further.

When making a ceiling using Knauf technologies, the result is more reliable and durable.

General description of technology

First of all, it is necessary to determine what is meant by the definition of “Knauf technology”. This is the customary name for one of the options for manufacturing suspended ceilings, in which the elements used to create a plane are plasterboard sheets, fixed on a special hanging frame. Taking into account the specificity of the materials used, the final result is durable and easy to manufacture.

Ceiling characteristics

Before deciding on the choice of the technology in question, it is worth familiarizing yourself with its most significant performance characteristics. So, among the advantages we can highlight:

• High speed of work. If all necessary tools are available and the qualifications of the craftsmen are sufficient, then it is possible to install such a ceiling in a medium-sized room within a day.
• Versatility. The ceiling using Knauf technology can be installed in a room of almost any size and configuration.
• Practicality. The plasterboard surface is easy to further process and allows the use of any chosen material. In addition, the technology implies the presence of some gap between the surface to be finished and the final coating, which can successfully level out almost any defects in the ceiling or close communication lines.
• Additional features. Making a plasterboard suspended ceiling allows you to lay a layer of soundproofing or insulating material, which can be far from unnecessary.
• Variability. Here we are talking about the fact that if Knauf technology is chosen as a ceiling finish, many various designs. A single-level ceiling can be transformed with the help of spotlights, and if desired, multi-level structures can be installed.

As a disadvantage, one can consider that a gypsum plasterboard ceiling using Knauf technology significantly reduces general level ceiling. This factor can be decisive, especially in rooms that do not differ in size.

Materials and tools

Before carrying out work, it is necessary to prepare everything necessary tools and materials. One of the features of the technology is that the work requires the use of precise measuring instruments. The fact is that the supporting frame required for the ceiling includes many constituent elements, which must be located strictly in level, and therefore the presence laser level welcome.

In addition, it is necessary to purchase special metal profiles from which the Basic structure. For these purposes, you will need two types of guides - one for installation around the perimeter of the room (PN 27x28) and the second - for installation of other frame elements (PP 60x27).

You also need to purchase the required amount of drywall in advance, which is laid out at the work site several days before it begins. The fact is that drywall absorbs moisture, so it will take some time to equalize the humidity level of the material and the room. If you do not follow this rule, the attached sheet may fail. Among other things, you will need special elements“crab” fasteners, self-tapping screws and a screwdriver with a special bit.

Carrying out work

If everything is ready for work, then it must be done sequentially, dividing it into separate stages.

Marking

One of the most important stages is marking. As mentioned above, it is extremely important to maintain maximum accuracy in installing the frame, which is ensured by defining a horizontal line that will run along the entire perimeter. If you use a laser level, the task is simplified as much as possible. If a water level is used, then two points are first marked on one of the walls, and then they are connected with a special tapping cord.

The procedure is repeated on all four walls. If everything is done correctly, the result is an even horizontal level, which will serve as a starting point.

Frame installation

The ceiling frame is made using special “U”-shaped hangers, which must be drilled into the old ceiling.

Before installing the longitudinal and transverse elements of the frame, markings are made and special U-shaped hangers are attached. Drilling will also be required for their installation. The distance between the fastening elements should be about 40 - 50 cm.

Then the longitudinal and transverse elements of the sheathing are installed, for which perimeter guides and hangers are used. It is important to ensure that all elements are in the same plane.

At the end of the work, you should get an even sheathing made of metal profiles and the sides of the cells are 40x40 cm.

Sheathing

The final stage of work is covering the frame with sheets of plasterboard. Everything here is quite simple, especially if a special bit with a limiter is used, which will not allow the screw to damage the integrity of the outer layer of the material. The sheets are sewn close to each other over the entire area of ​​the ceiling, and a gap of 2 - 3 mm should be left between the walls and the plasterboard.

As can be seen from the above, the Knauf plasterboard ceiling technology is not anything overly complex. If you meet the necessary technological conditions and have basic skills in handling the tool, you can cope with the task yourself.
