Plasterboard is a very convenient facing material. In addition, the price / quality ratio is significantly ahead of the same indicator in other building materials. Often, the ceiling is made of plasterboard plates, since due to the evenness of the material, it is possible to create an ideal surface. Today we will talk about how to attach plasterboard to the ceiling.
Arrangement of plasterboard ceilings
Let's look at the arrangement of a simple single-level ceiling of plasterboard sheets. Knowing how plasterboard is attached to the ceiling, you can create not only ordinary single-level, but also complex multi-level structures. But for the qualitative conduct of such work, you should know how to fix plasterboard to the ceiling.
Marking ceiling
Since there are emptiness in concrete floors, so that the dowels do not fail in them, you can use special fragile or shock dowels. But in the second case, the screw must be thicker.
After the profiles are fixed, proceed to the wiring of electrical wiring. For greater safety, the wires are hiding in a corrugated channel. Now consider how to mount plasterboard on the ceiling.
Installation of plasterboard sheets
It is necessary to take into account that drywall is quite overall material, and therefore it is better to enlist the help of a partner. Conduct the ceiling of the plasterboard alone is not very convenient, especially if you do it for the first time.
Sheet of plasterboard rises by two people. After that, one person holds the material, and the second - screws it. At the same time, consider that the extreme CD profile serves to fix two sheets, and therefore the edge of the plasterboard should reach the middle of the plank. The second half of the profile is designed to fix the next sheet of material.
How to attach plasterboard to the ceiling? At the fixing of one sheet, there are usually 60 screws with a length of 25 mm. They are twisted at a distance of 30 cm from each other flush with the plane of the ceiling, but it is important not to overdo it - it is impossible to break the paper of the material.
Since conducting the mounting of drywall on the ceiling, it is important not to damage the paper layer, it is necessary to use a special nozzle on a screwdriver or a screwdriver. It has a special lampshade, which during screwing the screws will rest on the sheet, thereby controlling the depth of the drowning cap.
By installing a sheet, do not forget about the need to remove wiring for lighting. If during
The use of drywall, as material for finishing work in the process of repair and construction is quite wide. With the help of this material, the walls are made, the formation of niches and partitions, as well as the ceiling trim.
In order to figure out how to fix plasterboard to the ceiling, you should carefully examine the recommendations on this issue. This work is not particularly difficult, but not professionals will have to work hard by mastering a new skill.
The surface created from plasterboard sheets has many advantages:
- the ceiling will be perfectly even - such a quality of the coating is difficult to achieve any other ways;
- the possibility of accommodating communications and isolation, hiding them under the coating;
- the ability to create unusual designs in accordance with your own ideas or designer project. It is possible to form devices from one or several levels, giving them various colors and shades using the finish;
- creating a unique lighting system, which is carried out using special lamps. There is an opportunity to choose not only power, but also direction of light flow, as well as the appearance of the lamp;
- you can form a plasterboard ceiling in any room. There are special varieties of this material having moisture resistance and refractory, which makes it possible to mount such a ceiling in the bathroom, in the kitchen, in the sauna, and so on;
- in the conditions of a wet room, it is possible to use conventional sheets, soaking them with a special composition. This option may be savoring than the purchase of special sheets. The issue of waterproofing such surfaces deserves separate consideration.
GLC fastening technology to ceiling
- Marking of the area of \u200b\u200bwork using a level.
- Fastening the UD profile around the ceiling perimeter.
- Fastening the suspensions to the ceiling.
- Installation of CD profiles to guides and to suspensions.
- Fastening sheet carp sheets on carrier profiles.
- Putclone joints and places of installation of self-tapping screws.
- Finish surface finish.
To obtain a qualitative result, it is necessary to adhere to the sequence of work, as well as responsibly approach the selection of drywall and fasteners. Save on such a design like a ceiling, it should be thoughtfully, otherwise excessive savings may affect the reliability and service life of the entire structure.
How to choose a profile and accessories for drywall
Creating a structure from several levels involves the presence of three types of fasteners: the initial, main and longitudinal profile.
- Profiles that perform supporting function must comply with the requirements of strength and withstand the weight of the entire design. The wrong selection of these elements can lead to deformation, for example, the provisions of the elements that from the outside will appear in the appearance of cracks or bends.
- In addition to the lack of aesthetic attractiveness, such defects are fraught with a violation of the integrity of the sheets of material.
- The mounting of the suspensions to the base of the ceiling is performed by anchors or dowels. All mounts should be made of metal. Plastic parts will not provide the necessary strength.
The guide profiles are attached to the suspensions, and the plasterboard panels are attached to them. Do not stop the choice on too thin sheets. 12.5 mm width sheets will provide sufficient structure stiffness.
Required tools
- screwdriver;
- level;
- pencil and measuring roulette.
Often, complete with profiles are provided with fastening elements, if they are missing, they must be purchased independently.
Marking of the ceiling surface and mounting frame under plasterboard
- Like all finishing works with the participation of drywall, the ceiling installation begins with marking.
- The base line is applied on the wall with an indentation from the ceiling of 10-12 cm. This line is a guide for mounting the guides, which you want to check with the level.
- Bearing parts need to be inserted into the profiles placed around the perimeter of the room, leaving the lumen for the possible deformation of the sheets during expansion.
- Fixing of plasterboard sheets is performed along carrier profiles. Sheets are attached to the guides across the longitudinal structures. Thus, the ceiling is formed from one level.
Mounting drywall to ceiling without frame
In the case when the room has small sizes and the formation of the frame can significantly reduce it, it is possible to fix the plasterboard to the ceiling on the glue.
- The surface should not have obvious irregularities, and should also be protected from moisture and freezing.
- Before applying glue, it is important to clean the ceiling from dust, dirt and fat spots. If the ceiling was covered with a putty or primer, you need to wait for it to complete drying.
- For the ceiling covering, which has significant irregularities, you can build a kind of drywall frame. You need to cut 10 cm wide strips, then paste them to the surface in the form of a mesh with square cells with the sides of about 50 cm. The process should be monitored using a level.
- Cutting sheets of plasterboard is performed by a sharp knife. A cardboard layer is applied on one side, a sheet is premounced in the place of the end, after which the cut from the reverse side is performed.
- Application of glue on the surface is performed by a special spatula with cloth.
- Fixing the sheet on the wall is performed using the holder, after which it is necessary to check its horizontality using a level.
- Bugs and other irregularities can be eliminated by climbing the surface with a hammer through a wooden bar.
- The seams that are formed between the sheets of drywall should not be located crosswise, so it is necessary to perform stacking in a checker order.
Mounting drywall for construction foam
Another material, with which you can strengthen the sheets of plasterboard on the ceiling, is the mounting foam. Before performing such an attachment, it is necessary to level the surface and treat it with primer.
- Before applying the composition you need to make several holes on the surface of the sheet.
- On the back side, the strokes of the foam rubber needed to create the springs effect when aligning the structure should be glued.
- Then the sheet is fastened with washers to the ceiling, leaving the cavity of about 10-15 cm.
Adjusting the sheet plane by the level, you can fill the foam cavity. After complete drying of the composition, you can unscrew the screws and screw the screws.
The finished surface should be coated with a layer of primer, close the seams with a reinforcing ribbon and coat the surface first, and after drying by the second layer of putty. After drying, you need to handle fine sandpaper.
For alignment of ceilings, builders and owners themselves are used by plasterboard sheets. This choice is explained by the excellent characteristics of the material: moisture resistance, light weight, ease of installation, so that in a short time without excessive noise and dust create a smooth, neat surface, give it a different texture or curly outlines.
The fastening technology of GLC sheets includes several steps and is performed in various ways, each of which can be carried out independently. The most common is the installation of a frame of metal profiles with a dowel or self-tapping screws. A wooden design of carrier and support beams can become a frame. Well, the cheapest option remains gluing a sheet of plasterboard to the ceiling.
Whatever technology is used, it is impossible to skip the planning stage. It includes measuring the height of the ceiling, the preparation of the tools and the purchase of materials. At the same stage, the ceiling drawing is performed, which indicates the scheme of placing the wiring and outputs for the lamps, the parameters of the level and outlines of the frame are given if the mounted figure type ceiling.
The initial level of the frame is measured as follows:
- laser beam or water level at an altitude of 1.5 meters from the floor on each wall surface, markers are made, which connect with each other with a solid horizontal line;
- measure the distance from the ceiling to the resulting line;
- in the lowest to the ceiling, the point is noted (at a distance of 25-30 mm from the vertex);
- exactly perpendicular to her on another wall make the same notice, which is connected from the first with the help of a strained thread or chocline;
- the same is done all over the perimeter of the room.
The resulting solid horizontal line is the lower level of the framework to which the profile or wooden beams is attached, we will tell about the distance or step between them below below. If plasterboard is planned to be glued, such a scheme for calculating horizontal markup is not used, however, we note that the significance of the foundation and durability of the structure depends on the correctness of these calculations.
Making framework
Consider how the GLC fasteners on the metal frame occurs. To do this, you will need a profile of two types - guide and ceiling (carrier). According to the finished horizontal markup with the help of dowels (or self-tapping) and the damper tape the UD profile is fixed, after which the ceiling plank is determined. This parameter calculates the number of frame suspensions and the distance between them.
To do this, on the ceiling perpendicular to the UD profile, in the direction in which it is planned to fix the sheets of plasterboard, at a distance of 50 cm make marks that connect the horizontal line. On these lines at a distance of 80 cm make labels for P-shaped suspensions.
With the help of a drill, holes are done under the anchor-wedge and insert the suspensions. Such a step of profiles is the most reliable: it strengthens the design and protects the plasterboard ceiling from the deflection.
So fix the planks to the suspension So that in the future the sheets of GLCs are smoothly, the self-tapping screws are strictly horizontally. After installing the metal frame, it is completed, proceed to insulation and sound insulation. Pouring wiring, reinforcement for ventilation or television will help the ceiling drawing diagram, compiled at the preparatory stage.
Finish work
Go to the installation of plasterboard. It is cut to the desired size, the holes are drilled under the lighting appliances. How the fastening technology occurs, from the planning stage to the finish finish, you will see on the video in which it is described in detail how to make a frame properly, make marking, calculate the step of the guide and carrier planks.
As can be seen, it allows you to securely secure the GLC on the ceiling allows a convenient scheme of the crossing of the profiles, because each sheet comes from the middle of the carrier plank. Often, metal jumpers are installed in a step between carrier straps, which even better fix the GLC to the ceiling, reliably protecting the edges of the sheet from sagging in the air.
Plasterboard are fixed with self-drawers, which are not very strong in order not to damage the paper layer on the drywall.
Fix the sheets of a screwdriver with a special nozzle Their number should not exceed 60 pieces on the sheet, that is, they are screwed up at a distance of 30 mm each other. Then the hats of the self-tapping screws, as well as the distance between the sheets close to the putty, after which the surface of the ceiling becomes smooth. The finishing finish provides for the processing of the resulting surface of the primer, staining, plastering or use of other methods of decorative design.
The most simple installation technology is described above, which provides for the manufacture of a frame under solid plasterboard ceiling. For the same principle, curious or multi-tiered ceilings are made. As can be seen from the article, the work does not represent much work, the only thing, it is only possible to correctly calculate the height and step of the frame profile, because the ideal basis is a pledge of durability and safety design.
In contact with
Installation of plasterboard on the ceiling is one of the most time-consuming types of finishing works. Therefore, in order to eliminate errors and minimize the costs of materials and time, you should carefully make the ceiling markup, prepare the necessary tools and materials. Immediately before installing drywall to the ceiling, it is once again to check, because in the process of installation, the errors allowed or very difficult, or not at all possible.
Installation of plasterboard ceiling is one of the most time-consuming processes.
Options for performing a carrier frame
Working with plasterboard plates implies three plates for base mounts to base:
- with the help of adhesive compositions;
- on wooden frame;
- on a metal profile.
Each methods have its own advantages, but is suitable only for certain conditions.
Installation with the help of glue, the least reduces the height of the room, but requires the ceiling surface to have high strength and evenness. With the help of glue, irregularities are eliminated not more than 1 - 1.5 cm. On the plastered ceilings, mounted slabs with a glue method, since GLC has a decent weight and is able to break down with the plaster. Also, with this installation it is impossible to install point lights.
Wooden frame for fastening drywall to the ceiling is suitable only in rooms with a small area and a constant temperature and low humidity. Wood varies very much of linear dimensions in fluctuations in temperature and humidity, therefore, with a large probability, the mounted ceiling will be covered with cracks.
Frames are best made from metal profiles - this is a lighter material with which multi-level plasterboard ceilings can be made.
It is much better to attach plasterboard to the ceiling with the use of special metal profiles that allow you to arrange multi-level surfaces at any height from overlap. Strength, ease and simplicity of fastenings are outputting a metal profile on leading positions among materials for carrying carcases.
Materials and tools
The main material in the device of the ceilings - the ceiling drywall with a thickness of 9.5 mm. Thicker has a lot of weight, and thin - arched, small thickness. And the same, and other require the installation of additional profiles to reduce the load on the frame or reduce the likelihood of the deflection.
Such materials will be needed:
- pNP or UD guide profile of 27 × 28 mm sizes;
- carrier profile of PP or CD sizes of 7 × 60 mm;
- suspensions for fastening support profiles to the ceiling (butterflies);
- dowels or self-tapping screws for mounting the UD profile to the wall and suspensions to the ceiling (depending on the design of walls and ceilings);
- cross-shaped connectors for docking transverse support profiles or to build a profile with a large room length;
- self-tapping screws to connect profiles among themselves, attachment to suspensions or crabs (so-called bugs or fleas);
- self-tapping screws for attaching GLC to a frame 20 - 25 mm long.
Tools and fixtures will also need quite a lot:
- screwdriver or drill with speed adjustment to fasten the plasterboard to the ceiling;
- perfederator or shock drill for drilling holes under the dowel;
- water or laser level;
- marking cord;
- stepladder or landing;
- backups to hold slabs during installation;
- cruciform screwdriver;
- scissors for metal cutting profiles;
- long cord to control the mechanism of installation of carrier profiles.
Marking and installation of the carrier frame
Marking under the fastening of the frame begins with determining the level of installation of the guide profiles. To do this, on the walls, starting from any angle with the help of a water or laser level, transfer marks to the remaining angles. Then, with a marking cord, the control line is discouched throughout the perimeter.
Performing calculations and drawings One of the most important points when installing a ceiling of hypostertone, having allowed the slightest oversight, you can spoil the entire end result.
If the installation of point lamps is not supposed and it is required to reduce the height of the room at a minimum, then the support profiles can be mounted at a distance of about 30 mm from the lower point of the ceiling. Most of the tips are reduced to finding this lower point and transfer it to the nearest wall and from it to be repelled. But nowhere does not say how to do it.
It is much easier to note around the perimeter temporary horizontal at a distance of 20 - 25 cm from the ceiling. By pulling the cord between any dots on the opposite walls, you can quickly find the lower ceiling level and transfer the time horizontal to any value.
For fastening the suspensions, you also need to put markup. Here it is necessary to proceed from the size of the plates and the width of the walls. It may happen that it will be necessary to fix the sheet strip width of less than 20 - 25 cm. So do it undesirable. It is better to cut the sheets of plasterboard symmetrically from the opposite walls with the condition that the minimum width of the attached band was at least 25 cm.
The position of profiles relative to the plates can be different. The most practical laying of sheets so that carrier profiles passed across GLC at a distance of 50 cm (for sheets of 2.5 m long).
Between the laid profiles, jumpers are installed at a distance of half of the width of GLC. The jumper connection is performed using crabs.
Installation of plasterboard plates
Attaching the slabs to the frame is better to perform together, however, if there are backups and some experience, you can do it alone.
The stoves are stacked so that the edges followed the middle of the profile and the gap of 3- 4 mm remained between adjacent plates. In the neighboring rows, the sheets are placed to make the seams not to be on the same line. Along the long sides of GLCs usually goes chamfer or thinning for the convenience of seaming seams. For the same purpose, on the ends, you also need to remove the champions with a special plane or mounting knife. The chamfer is removed while the plates are not yet fixed.
To engage in plasterboard ceiling can be one person - using the backups, but in case you do it for the first time - we advise you to do this with someone's help.
The attachment of the GLC to the ceiling is performed using self-samples with a step of no more than 155 mm. From the edge of the leaf, the screws must be at a distance of 20 mm. Self-tapping heads must be completely recessed into the surface, but at the same time should not break through the paper layer. If this happened, then the self-sufficiency should be screwed into another, intact place. To avoid marriage in work, you should not use a screwdriver at maximum speed. An experimental way to establish the necessary effort of the friction clutch, and it is better to use a nozzle with a special skirt that does not allow to deepen the self-samples above a certain value. The protrusions from the nozzle must be even, without work out. Otherwise, the self-tapping screw will be kept loose and often break.
Be sure to fasten the plasterboard on the ceiling, it is necessary to check the correctness of the electrical wiring and mark the places where the lamps will be installed in the future.
Common mistakes
The most common error during installation of drywall is incorrect calculations and markup, when a plot of several centimeters wide remains.
Second error - fastening sheets directly to the guide profile. First, the fastening is obtained along the very edge of the sheet, where it will be sharpened, secondly, the rigid clutch of the ceiling with partitions and walls can lead to cracks when the temperature drops. Fix GLCs better to profiles that are laid in close proximity to the guides.
Plasterboard sheets (GLC) are a very convenient and favorable facing material that gives price-quality ratio unsurpassed result among building materials. Most often from GLC arrange the ceiling, and if you do not know how to fix plasterboard to the ceiling correctly, then this page is at your service.
In addition, there is a video on this topic, which will help you clearly understand the intake subtleties.
Arrangement of plasterboard ceilings
Marking ceiling
Marking ceiling
Mounting metal carcass
- On line, broken around the perimeter, screw UD profile so that its lower part exactly coincides with the line.
For attachment, it is best to use a plastic dowel-dubber with a diameter of 6 mm and a screw, with a diameter of 4-5 mm. The length of the screw and dowel will depend on the wall density.
- On the lines shot down on the ceiling, attach P-shaped suspensions. It is better to use the inner holes for fastening the pad, and not the ears, since the suspension attached to the ears, under the weight of the GLC, will pull a pair of millimeters under the weight, and this will violate the level of the plane.
The diameter of the dowels and screws is needed the same as for the wall.
Council. In concrete floors there are emptiness and so that the dowel does not fail in them, it is necessary to use fragrant dowels or, if there are no, shock dowels.
But the factory ratio of the shock dowel-screw is too weak, so screwed should be replaced with a thicker.
- Now cut CD profiles to the desired length and insert them into UD profiles installed around the perimeter.
Profile cut on 5 mm shorter absolute distance between the walls, and it will come in free. - In order to level the CD profiles, you need to stretch the thread under them, and in order for these most profiles to be pulled out - adjust each middle suspension under the profile, tightening it above the plane level.
- Passing the pitch from the wall to the wall, across the CD profiles, consolidating it to the UD profiles with minor self-draws.
- Expose every profile on the strained thread, bonding it with the suspension of small self-drawing for drywall profiles.
Similarly, fasten the CD profile with the UD profile. Sticking ends of the suspensions are rejected to the sides. - Divide all the electrical pipes needed for lighting and hide them in a corrugated cable channel. Next, we will look at how to fix plasterboard to the ceiling, or rather, to a metal frame.
Installation of plasterboard sheets
Council. Since it is necessary to mount the plasterboard, without breaking through the paper on the sheet, then use a plasterboard nozzle for this.
It is equipped with a special lampshade, which, when twisting the self-pressing, rests on the sheet, controlling the depth of drowning the cap.
- Do not forget to output through the GLC wire for lighting in the right places. If you have some sheets when installing drywall, some sheets did not come up for several millimeters - do not be discouraged - these slits are filled with a spheolder or fogenfuller.
- We looked at how to mount drywall, and now it needs to be prepared for the shplanyow. To do this, all the screwed screws are closed with a spheolder.
- The seams between the drywall sheets can be squeezed with a sticky ribbon mesh, and then scope (see).
You can also close these seams to the fogenfuller, which is also a putty, but when frozen has great hardness and durability. - After drying off the seams and screws, you can proceed to the plasterboard splock.
Conclusion
We looked at some nuances of such arrangement as plasterboard on the ceiling - how to fix it properly and how to prepare it for finishing. For mounting more complex multi-level and curly ceilings, you need to learn how to do smooth monomular, living room, bedroom, understanding of the device that will allow you to go further and collect more complex designs.
