How to make an arc from a profile for drywall. How to bend a profile pipe for a greenhouse: the simplest methods and rules for making blanks. Basic conditions for flexion

Hello friends! Recently, my friend and I made repairs, and I found that he is not very good at how to bend drywall. While I was doing other things, a friend broke 5 blanks! And all because he treated the moisture.resistant GCL, as with the usual one: he hooked with a needle roller, wetted with water and tried to bend. Since the material did not absorb the liquid, the result was logical. What to do, I had to show how to work correctly with different types of GCL. If you want to make an arch, but do not know how to bend the sheets, use my instructions.

If you want to make an arch or figure made of drywall, then first of all you need to learn how to bend metal profiles on which circles and waves will be mounted.

First of all, it should be noted that two types of guides are mainly used for figures in frames, this is UD and UW, where the sides are not profiled, and they are easy enough to cut.

But this does not mean at all that for this purpose the type of CD or CW cannot be applied. it is practically possible, it’s just more difficult to technically.

So, how to bend a metal l-shaped carrier to make a circle or wavy fishing line for a trimmer from it? You need to cut the shelves on both sides to the ground. The incisions themselves must be at the same distance, so that the bend is smooth, without sharp differences.

Suppose you need to bend a circle with a diameter of no more than one meter or a narrow arch with a steep bend (see. as well as how to make an arch of drywall), which means that the cuts will be more frequent and in this situation is quite acceptable 5 cm.

Slots must be done strictly opposite each other and monitor the uniformity of the step. You can get additional information on this issue when watching a video of the video on this page.

The profile does not always bend the sole inward, sometimes it is necessary that it be outside, then each petal cut into a cone so that they do not pile up to each other. And if you need a bend to one side, then the side is cut on the convex side and the sole, as in the photo above.

How to bend drywall in a wet way

To bend the drywall in a wet way, that is, by soaking it with rags moistened in water, you need to cut off the panel of the required size and treat the expected convex side with a spiked roller.

GKL pierced with spikes on both sides is covered with wet rags and left overnight. After that, the material can bend the figures on the metal frame for drywall.

But this method takes a lot of time and this, of course, increases the price of the issue, because the master spends on the process instead of several hours for a whole day.

Key varieties of drywall profiles

So, in its purpose, all profiles can be of two types:

And the representative of each group must fulfill its specific function. The marking of the elements described in the article is made according to KNAUF technology, all of them are made in standard sizes:

  • UDs are ceiling guides;
  • CW. barrier products;
  • UW. partitioning guides;
  • CD. ceiling rack.

note! If you correctly connect elements of different types, then you can get various plasterboard structures, among which different boxes, partitions, suspended ceilings, etc.

The sizes and cross.section of these elements are also different.

A variety of rack ceiling profiles

Many people know the inappropriateness of suspended drywall ceilings to mechanical influences. But the profiles should be not only light, but also strong, in order to hold the entire structure with GKL (otherwise all this can collapse on the heads of the residents). The rigidity of the frame is largely provided by the ribs of CD profiles.

These types of profiles are rightfully considered the most popular. In most cases, they are used for finishing/construction work. Due to the standard waste sizes after working with these elements there is almost no. It is easy to guess that the main load of the entire structure falls on these profiles. Thanks to them, the reliability and rigidity of the frame, as well as the quality of fixation of drywall sheets are ensured. The thickness of such profiles is different, but thin products are less reliable, which is obvious, and they need a large number of fasteners for installation (we will tell you more about these elements a little later).

As for the length of CD profiles, it can be from 270 to 450 centimeters. But in reality, elements of 300 and 400 centimeters with a cross section of 6×2.7 centimeters are usually used.

Variety guide ceiling profiles

Such profiles are used to create ceilings, walls and various boxes in order to strengthen. Products are installed along the perimeter of the walls/ceilings, and still standing profiles are inserted into them.

A kind of basis for the plane is formed from the guide ceiling elements, which will subsequently be sheathed with drywall sheets. The length can be 300 or 400 centimeters, while the cross section is 2.8×2.7 centimeters. All elements are quite thick (thin are not used for ceilings), which ensures reliability. The best option for the construction of wall frames.

note! If you want, then the profiles for you can be made by individual order. In any case, in the manufacture, high.quality galvanized steel is used, which increases the resistance of elements to the influence of the environment, temperature changes and other things.

Variety Particular Profiles for drywall

We continue to consider the types of profile for drywall. So, if we talk about partitions, then, according to experts, there are several varieties, and their use, respectively, depends on the future thickness of the design from GKL. So, UW profiles (in accordance with the same marking of KNAUF) are used in the partitions as guides. Their length varies between 200-400 centimeters, and the width can be 4-15 centimeters.

There are also rack products (or, in other words, CW profiles), which are performed with notches that facilitate the laying of cables. Used in drywall regulations and are the supporting elements of the entire frame.

Such elements are intended for use in vertical structures. The length can be from 276 to 600 centimeters, while the cross section is 5×5, 7.5×5 and 10×5 centimeters. By the way, profiles are most popular, the length of which is 300 and 400 centimeters.

Separate group. corner, beach and arched products

As for the aoric types of plasterboard profiles, they are with holes and incisions necessary to give profiles flexibility. If we talk about sizes, they are the same as in ordinary elements, while the stiffness indicator is much higher. Arched profiles are used in order to receive arcs.

There would be nothing complicated in the formation of arcs, but in reality this is not so. Although experienced specialists are easily coping with all this.

But with the help of beach elements, various planes are aligned. For example, when plastering walls/ceilings. The length of such profiles is 300 centimeters. If you plan to create a smooth plane, then you just can not do without such an element (for example, to create slopes).

Important information! Lighting profiles for drywall noticeably facilitate the difficult work of builders. They are attached in complex places in order to create a flat surface. Thanks to the material from which these profiles are produced, increases their resistance to various kinds of negative external influences.

Finally, there are also corner profiles. They are used, as you can guess from the name, for alignment/strengthening of angles (for example, to protect the ends of the partitions). Each element has holes, the diameter of which is 0.5 centimeters necessary for better filling during the application of a putty mixture.

Various fasteners and additional elements

In addition to the profiles themselves, in the process of installation, other standard elements are used, which should also be prepared in advance. We will get acquainted with each of these elements in more detail.

  • Straight (ordinary) suspension. Designed for fastening a rack or ceiling profile to the working surface (see the figure).
  • Anchor suspension. With its help, ceiling profiles are also attached, but exclusively to the ceiling. Each element has a traction and clamp, allowing to adjust the position of the suspension.
  • Extension. With its help, strips of a metal profile are connected in a variety of combinations.
  • Type “crab”. It is intended for a cross.shaped connection (and all types of profile for drywall can be used), and strictly at a right angle, structural elements. As a rule, with the help of a “crab”, ceiling profiles (of course, in one plane) are connected during the installation of the crate.
  • Two.level connectors. As you have already guessed from the name, with the help of these fasteners the profiles are attached at right angles, but already at different levels.
  • The last elements are self.tapping screws and anchor dowels. Are intended to connect the elements of the frame with each other or, as an option, with the main overlap in the room.

The illustration below shows all the described elements in the sequence in which they were given.

Preparation and application of markings

In order to cut drywall, you will need the following:

  • Use a knife only with a sharp blade;
  • If it is supposed to be attached to drywall both on the ceiling and on the walls, then at the beginning it is necessary to sheathe the ceiling, and only then start the walls;
  • If you need to cut off the drywall along a complex trajectory, then first cut off the length and then the width.

Remember that in the process of work and fastening drywall it is very important to use as many whole stoves as possible. So you will reduce the costs of materials, the work will be less, and the process of skin will go faster

Therefore, you need to carefully measure and study the surface with which you work, and then draw up such a plan for using the plates so that you have to cut as little as possible.

If you need to attach drywall to a large area, we recommend using 3.6-meter slabs instead of 2.5-meter. So you will save time and material.

To professionally cut drywall, use high.quality tools. If sheets of large sizes (120 cm wide), then it is better to cut them, leaning against the wall at a slight angle. And small sheets (up to 60 cm wide) can be cut on the floor. If you first cut drywall, then it is better to practice it on the floor. In the beginning, you need to decide which side to cut drywall to. To do this, make sure that the drywall sheet will be turned to you with the front side. It is on this side that the incision will be carried out.

If you do not know what is better to cut drywall, then from your experience we can tell you that in most cases, it is best to use a good stationery knife. But sometimes you have to use other tools. For example, a hacksaw for drywall, it is convenient to use for cutting holes of various shapes.

The minimum set of tools that you will need when cutting drywall.

Smart advice. If you cut drywall, applying it to the wall, then put down a few wooden bars down. This will facilitate the cutting process and protect your fingers from damage.

First you need to use a tape measure to determine the size of the cut. Do this very carefully, otherwise the stove may simply not fit. it turns out either too small or too large. Also make sure that the vertical edges are aligned in the center of the crate, otherwise the locations of the plates will not be sufficiently tough. Measure with a roulette and make a pencil mark in the right place. In our example, we want to cut the stove in half, so we make a mark in the middle.

It is very important to make accurate measurements, otherwise you will spend a lot of time and money to correct errors in places of joints. Be especially careful when you work alone

To get the perfect straight cut, use a flight. If you want to achieve the results of a professional level and you have to cut drywall often and a lot, we advise you to get a big flight and not use home.made or handicraft tools.

Move the flight on drywall until it reaches the desired mark.

  • Use a knife only with a sharp blade;
  • If it is supposed to be attached to drywall both on the ceiling and on the walls, then at the beginning it is necessary to sheathe the ceiling, and already with a pato to start the walls;
  • If you need to cut off the drywall along a complex trajectory, then first cut off the length and then the width.

Sovetremont.com

Absolutely all novice home.repair masters who decided to get by with their own hands want to bring something new to the interior of their home. And then they will come to the rescue of building an arch or even make a suspended ceiling from drywall with their own hands.

The forms of these products have a fairly wide variety, it all depends on finance and imagination. Arks are mainly made by rounded arches, suspended ceilings are no exception, you will find a bright example of this here.

Home craftsman, looking at such a design, is perplexed by how the end of such a ceiling is made and how it is possible to bend, and at the same time screw a drywall sheet without breaking it.

Now I will try to tell in detail and show in the photo how I do it myself. Namely, what needs to be done with a metal profile in order to take the silhouette you need, or how to bend any radius of drywall.

How to prepare a profile

What about the size of the profile, I mainly have to deal with 27/28mm. This is the so.called “guide”. Perhaps this is the most commonly used material in combination with 60/27 (used for jumpers).

In order for the guide profile to repeat the radius drawn on a sheet of gypsum, it is necessary to create a non.cunning action with it. You need an angular grinder of not large sizes that should easily be held with one hand in a neglected state, and protective glasses.

We install a trimmed disk for metal on the corner grinder, cut the notches on the profiles every 5cm. Here we must clarify; The cooler the radius of the arch, the more often and less the distance between the incisions on the gland.

Pay attention to the given photo, I prepare several blanks at once, about one meter long, if you try to fasten a long blank alone, most likely it turns out not quite evenly and accurately.

What in the end gives such a technique, I think you yourself guess, the cut profile27/28 turns into a semblance of a rope, it can be calmly screwed with screws to drywall gradually bending and directing along a given radius.

Probably, I figured out this if something is not clear I will be glad to answer you in the Комментарии и мнения владельцев below the article, do not be shy and ask questions!

How to bend drywall

Now I move to the most interesting. Having rummaged on the expanses of our Internet, I found that everyone mainly advises to moisten drywall with water so that he was bent easily. I will not argue, since the option really works, I was curious a couple of times to apply it.

It just turned out that it is not entirely justified by labor and time to wet and bend this option. Plus everything I am sure that a person who does not engage in the repair professionally does not succeed. Therefore, I don’t want to recommend this method.

But another option is much more effective and easier. It is on it that I insist, the universal majority of my colleagues work this principle. All you need is a set of; Chancellery knife, simple pencil, roulette, level level not more than 40cm., and actually the material itself, in advance cut in the form of a long strip (again no more than one meter for the convenience of screwing alone without outside help).

Hugging plasterboard under the radius of the suspended ceiling

On a pre-prepared strip, using a roulette and pencil, apply dashes every 5-10cm. (see the photo), the distance is due to the radius of the semicircle on the ceiling or arch, the dashes should be placed on both sides of the workpiece.

Next, we apply a small level (you can still a thick ruler, a piece of profile 60/27 can be applied to the “extreme” by dashes and at the same time press it so that it does not move.

Having taken the clerical knife with his other hand, we draw a blade along the drywall slightly pressing it into the material, and at the same time, relying on the level as on the guide bar. We repeat this not a tricky operation along the entire length and markup.

At the moment, “gypsum” can be lifted to the top to the frame and fixed with screws on drywall. As soon as you press the material to the frame, it will immediately begin to break on the notches of the knife, repeating the silhouette of a suspended ceiling radius. If you have an assistant, then you can prepare stripes much longer, quite really from the edge to the edge of the drywall sheet (2.5m).

Now it remains to establish an arched plastic corner, its peculiarity is that it perfectly levels and strengthens the edge of any non.straight box. Special skills for installing such a corner are not required, in this article everything you need to know.

In principle, there is nothing to tell on this, then the alignment of the corner with gypsum plaster remains, complete finish putty and stripping putty. Painting the ceiling or if it is an arch, then it may be wallpaper.

How to bend drywall with a semicircle: methods and features of the process

Often in the design of the premises, non.standard forms of surfaces are used, for example, arch. But how to bend drywall with a semicircle in order to get an even bend and not break the material?

Whatever tricks are invented to solve this problem, because the GCL is quite fragile in structure. And to make from it a uniformly curved surface without cracks, without resorting to special technologies, is quite difficult.

Where curved surfaces are used

Of course, you can not bother and make straight.line forms simple in your manufacture. Even when creating a multi.level ceiling, you can assemble the structure, observing the angle of 90 degrees.

Bending drywall for an arch

There are many designs where a semicircular drywall is used: arches, multi.level ceilings, partitions.

But the ceilings with a two.tier structure, and even with smooth contours, are much improved by the external design. Due to smooth lines, a feeling of lightness and completeness is created.

The arches in the doorways will visually expand the space, creating a feeling of spaciousness even in small rooms in the area.

Curved forms are perfect for the design of both living rooms and bedrooms. And due to arches and semicircular bends in the openings, it is easy to create a smooth transition, for example, from the kitchen to the hall.

In any case, light semicircular bends will improve room design.

What materials can be used

Gypsum plasters also provided for the moment as bending of sheets. Yes, this is precisely what there are special tools and materials.

Cutting to bend drywall

There is for some reason to moisten the sheet, the cut method will be convenient. This is also a dry method, only more manipulations are carried out with a sheet. Do not be afraid, this method will not lead to injury to the sheet.

  • On one side of the sheet along the fold line, make the cutter with the cutter at a five.centimeter distance from each other (a knife is also suitable);
  • Sprinkles must be done on the convex side of the sheet. more precisely, the side that will be convex;
  • The smaller the alleged radius, the less incisions should be;
  • The depth of the sawdust is approximately 2-3 mm to the cardboard layer of the other side;
  • The side with incisions must be straightened with a fan;
  • The cuts should be filled with putty to fix the structure.

If the cutter for cuts is used, then the cuts can be both a P-shaped and V-shaped. That is, a drywall sheet can also take the desired shape. Work carefully and everything will work out.

The device of the circle and second level: Stages

So that a volumetric circle appears on the ceiling, it needs to be drawn. A simple wire screwed into the surface of the drywall with a screw with a pencil at the end will help. Improvalized circulative will allow you to carefully draw a circle of the desired diameter. If the ultimate goal is not a circle, but an oval on the surface, then for its receipt it will be enough to combine two circles with a intersection equal to the width of the oval.

To install the UD profile, to the outlines of the circle, small notches are made on it every 5-7 cm, thus increasing flexibility. The cut profile is easily bends in the right direction. In this position, it is attached to the frame of the upper tier, screwing the screws directly into the surface of the sheet.

You can work on such an algorithm not only with UD profile, but also with the UW profile, the width of which is from 50 to 100 mm, which means that it allows you to fix the second level with a higher depth.

The next step is a fishing line for a trimmer on a wall at a level with a circle. The profile of ud is attached to it. Connect a circle with a parietal profile using CD elements and self.tapping screws, if the circle was assembled on the basis of UD, suspensions, if UW was involved in the process.

Both round and oval ceilings are sheathed with plasterboard sheets by analogy with ordinary multi.tiered structures. Be sure to take into account that the vertical plane of the sheets will succumb to deformation, so stripes of optimal width are cut from them, cut in a step of 5-7 cm from the convex side of the bend. The blanks fill the cavity of the circle, removing the excess material with the mounting knife. This option allows you to make a semicircle or a circle with a large radius with a dry method.

The wet method involves abundant wetting of drywall sheets with a roller or brush with a device of small holes in the upper layer of the coating (use a shilo). The moistened sheets become more flexible and do not break during the installation of figures with bends.

The finished design is sheathed, the joints are processed, primed, put down and painted, according to the design project.

How to install a metal profile for drywall to the walls and ceiling?

To carry out the fastening of the metal strips of the frame to the wall, straight suspensions are used, which are screwed through special holes with self.tapping screws. The suspensions are attached to the concrete wall with anchors or dowels, the holes under which are made by a peorator. The frequency of the suspension installation is 600 mm. When performing installation, you should control the fishing line for the trimmer of their fastening.

In exceptional cases, as an alternative, it is possible to apply a profile of 60×27 mm profile, bending them in the form of the letter “G”. Some experts claim that this method is even better. it more rigidly fixes the bar.

Sometimes, when installing a frame from a metal profile for drywall, it needs to be lowered by a significantly larger distance than standard suspensions allow you to do it. What to do in this case?

For these purposes, a sliding suspension system is used, which consists of three elements:

profile, drywall, bend

One knitting needle is attached to the ceiling, and the second is adjusted to the desired height. The bracket is inserted directly into the profile and fixed.

How to fix drywall

From theory we move on to practice. The installation process consists of the following stages:

Before starting work, it is necessary to accurately remove the size and draw a plan. If we are talking about fastening gypsum on the walls, then on the plan you need to display only the frame

At the same time, it is important that a support bar is located in every corner. The distance between the intermediate supports should be the same, and it is desirable that they do not have the edges of the gypsum sheets

If we are talking about any design made of drywall, then the dimensions are removed in approximately the same way. At the same time, the graphic image will make certain amendments and clearly demonstrate how well the object fits into the room.

The next step is the assembly of the frame. First of all, guides are installed. this is a “P” of a figurative wide profile, which is attached from below and from above the walls or along the perimeter of the ceiling (if it is only about the ceiling). Guides not only set the vector for installing supporting profiles, but also serve as lighthouses

It is important to install them perfectly evenly. If a gap forms between the wall and the profile, then it is necessary to insert either dense cardboard or wood (depending on the size of the gap)

Unlike the frame itself, the guides are attached with dowels at a distance of no more than 30 cm from each other. After installation, the guides are mounted by the frame itself, all the initial data are indicated in the drawing.

If gypsum is mounted on the wall, then thermal insulation must be used. Minvat is optimally suitable for these purposes. reliable heat savings will provide foam. Foam and other insulation are not suitable.

For separate structures, insulation is not necessary, but the void must be filled out. Firstly, to suppress noise, and secondly, so that various parasites do not start. It is more advisable to use glass wool in a private house, there will be enough ordinary cotton in the apartments

In both cases, it is important that there are no voids left

The final stage. installation of drywall. The procedure has its own nuances that need to be considered in more detail.

Before making a round wall, we will find out what it will give

First of all, perhaps, information should be summarized about such a convenient, but not particularly durable drywall. This composite material is also known as dry plaster, and is actively used for wall decoration, even in rooms with a high level of humidity or fire hazard using especially stable sheets. However, unlike decorative coatings, which are applied several millimeters thick and immediately are a finish option, sheets of two layers of cardboard, between which a frozen gypsum layer is enclosed, finishing is required.

But if you do not pay attention to the decorative component, drywall is a very valuable development, because you can make a round wall from it quite quickly, only slightly moisturizing. Today, sheets are produced with a thickness of 6, 8, and 9.5 millimeters (the most popular dimensions, but there are thicker) that bend relatively easily, especially the first type called arched. massive modifications are necessary in cases where a strong base is needed, for example, so that niches from drywall are not only decorative.

From this we conclude that almost no other material can be applied, say, for curved walls or for hinged ceilings in the form of complex figures (especially in the latter case) neither plywood nor plastic have the desired supply of flexibility and durability. Brick is all the more suitable for light structures. As for the roundness of the drywall walls, it is needed, first of all, in cases where it is required to slightly increase the area of ​​one room by removing it in it, by reducing the area in the adjacent room where there will be no angle. In addition, the protruding parts of the layout are damaged more often rounded.

The second method is dry (but requiring additional finishes)

The popular option, however, often “masters” miss an important aspect of how to bend the drywall correctly, which is why the result is an unreliable design that subsequently fed to detach the upper layer of finishes, the appearance of cracks and “walking” of the entire material.

With a high.quality and detailed implementation of the method, you can form a bending of drywall with a radius of less than 1 m.

  • Cut the workpiece cut. It is placed on a strong surface with an even edge, for example, on the table to the top of the side that will be from the outside. The entire length of the workpiece across it is made by straight lines at a distance of 4-5 cm from each other.
  • With the help of the rule and the construction knife, cuts are made on the marks. It is necessary to cut out only cardboard, without deepening it very much into gypsum, so as not to make it.
  • Pulling the sheet to the edge so that an incision is located above the edge of the table, the sheet is blown up without tearing the second layer of cardboard.
  • This continues until cuts and chips are made on all marks. Typically, on this “Woe-Master” they finish, screwing GKL in this state to the prepared frame. However, this is not the end of the method, how to bent drywall through the correct. The sheet neatly moves to the prepared stand with the required bend, ups up.
  • The entire surface is thoroughly primed so that the primer falls on all surfaces with a bare gypsum. With the help of putty or adhesive composition, all incisions are sealed, the surface is opened with a layer of a solution of at least 1.5 mm.
  • A reinforcing fiberglass mesh is superimposed on top, pressed with a spatula into the solution. Everything is leveled, smoothed out.

Only after the solution is completely dried, you can use drywall for installation for a prepared frame.

How to bend drywall and metal profile for it

Drywall, as a rule, is used to create perfectly even surfaces. However, crank interior objects made of drywall are becoming increasingly popular among designers and homeowners. doorways, relief multi.level ceilings, niches with curved lines. You can create such masterpieces yourself. All that you will need for this. materials, tools and our detailed instructions. Our tips will be useful not only to fines, which, due to their professional duties, are dealing with drywall almost every day, but also ordinary owners of apartments and houses.

If you decide to diversify the interior of your home with one of such unique objects, you first need to find out how to bend drywall and how to make a curved frame for its fastening. And our article will help you in this.

How to bend drywall

In order to give a drywall sheet a curved shape, you will need the following:

First of all, it is necessary to cut off a piece of drywall of the size you need. This operation is quite simple: place the square along the edge of the drywall sheet and with the help of a knife make a deep slot. Then bend the sheet along the cut line to break the gypsum layer. And the last thing you should do is cut a paper layer from the opposite side. Do not forget to make sure that the cut fragment is suitable for you in size.

Drywall cutting.

There are two ways to give a curved drywall to the sheet of a curved shape. moisturizing its surface and applying parallel incisions. The first method is used in the case when it is only necessary to bend the drywall sheet slightly. The second method will be useful when the sheet needs to give a large curvature. In the latter case, there is an alternative option: you can use two layers of drywall with a thickness of 6.5 mm (the so.called arched drywall), since it beams easier, or layer 6.5 mm plywood plus layer 6.5 mm drywall.

Based on our own experience, we recommend that you, before starting to work with a large sheet of drywall, practice waste. Having done this several times, you will understand how easy it is to bend drywall at home. such work is quite affordable for you.

Method one: cuts on one side of the sheet

This method is used mainly when creating door arches, where it is required to bend drywall to a large radius. In this case, to bend a drywall sheet, you must make notes on it every 3-5 cm. Put the sheet on the floor or lean it against the wall and, using the ruler (in our case, the construction level), make a lot of parallel incisions. Cutting the paper layer on one side of the drywall leaf will easily bend it, while the remaining intact layer of paper on the other side will hold the sheet from destruction.

Tip: Remember that you should make notches on the outer surface of the future curve, otherwise you will not be able to bend drywall correctly.

Application of notches with a knife.

Next, you must break gypsum in the sections of the cuts to make the sheet very flexible. If you did everything right, drywall will bend very easily, and you can easily give it the desired shape.

Bending drywall in the arc.

Now it remains to align a fragment of the future arch with the plane of the wall and fix it with self.tapping screws. Perform all operations with great care so that the result of the work meets your expectations.

We recommend that you fix the curved fragment of drywall every 3-5 cm. Use an electric screwdriver to adjust the torque, this will allow you to tighten the screws quickly and correctly. In addition, be sure to make sure the strength of the metal frame to which you fasten the drywall, otherwise the arch will not be stiff enough.

Fixing a curved drywall sheet.

It may seem to you that the arch created by you does not look attractive enough. We hasten you to assure you that you will not notice any flaws after glue the edges with a reinforcing mesh and apply several layers of putty.

Second method: watering water

You can give a curved shape to the drywall by moisturizing the posterior surface of the sheet. If you need to bend the sheet quite strongly, you should wet not only the rear, but also its front side. Drywall sheets must be laid on an even concrete floor and moistened with a roller or garden sprayer. If drywall you need to moisten quite strongly, you can use the sponge for these purposes. Remember that excess water can easily damage the material, so moisturize drywall should be gradually.

Moisturization of a drywall sheet.

Before you start bending directly, the water should be absorbed into the drywall for about an hour. Work with great care, as a wet panel is very easy to damage. After you give a drywall sheet the desired shape, you must ventilate the room to get rid of excess moisture.

Tip: Do not moisten the sheet too much, otherwise the paper will be easy to break.

Having fixed one of the edges of the sheet, gradually bend it, screwing each subsequent self.tapping screw. Act with great care and patience to get a smooth curve. Self-tapping screws should be located at a distance of no more than 10-15 cm from each other, otherwise your curve will turn out to be a wavy.

Screw the screws carefully so as not to damage drywall, otherwise you will have to spend more effort on the finish leveling of the surface with a putty.

How to bend drywall and a plastic profile for drywall?

Thinking over the interior of the apartment, we often need to smooth out the corners or make rounded arches in spans. it looks modern and stylish. However, many starting repairs do not know how to bend drywall and profile for it to make curved structures on the ceiling or walls.

Professionals recommend using a special brand for the construction of semicircular structures, which is designed for these purposes. the CC, that is, the plasterboard sheet of arched. This type of building material has a lower thickness and increased elasticity. Thanks to this, he bends very well and takes the desired shape.

However, this type of drywall is more expensive, and due to the fact that its thickness is many times less than the usual 6.5 mm, then it needs to be attached in two layers. That is why the construction craftsmen in order to save on the material came up with several ways.

Bend the Profile for drywall

You can ask the question: how to bend a profile for drywall, because it has a hard metal frame and bends with difficulty. It turns out very simple, it is necessary to make small cuts on it on 2 of 3 shelves of the profile after about 50-70 mm each.

You can do this with a corner grinder or ordinary metal scissors. Cuts must be made taking into account which part is supposed to attach the profile: either cut both parts of the profile, leaving the whole only the base, or cut the base and one of the side shelves of the profile.

The very first one you need to remember is to bend drywall not in width, but in length.

The first method is dry.

To bend drywall, you can use the so.called “dry method”.

Build the frame of the form that is required, and then attach the drywall sheet of the required width using an electric screwdriver and screws to one edge of the frame, and slowly bend it.

In the course of his work, he is also attached to the base with the help of self.tapping screws. Bend a drywall on a dry one better together.

The second method is wet.

If you have an idea in the interior to use highly and extended lines, then it is best to bend the drywall in a “wet way”, that is, wet it.

Thanks to this method, the risk of breaking a drywall sheet and spoil the building material decreases. Before work directly with drywall, it is necessary to build a template made of wood-bearing plate or plywood.

Do not forget to make the radius of the template less on the thickness of the leaf of the radius of the final bend. After the template is ready to go to drywall. So, the concave side of drywall must be slightly wetted with water. It is necessary that water penetrate the material and soak its gypsum part. To do this, process the entire surface of the sheet with a needle roller. this will make small punctures and will enable water to penetrate inside.

For convenience, water can be applied using a construction roller or brush. After this work is done, you need to wait an average of 10 minutes, and only then proceed to the bend. After time, you can proceed to the direct bend of the sheet. You need to act carefully, since there is still a risk of breaking it. As in the first case, drywall should be placed on the base, but fixed with tape. After the drywall is completely dried, it is mounted to the frame with self.tapping screws.

The third method is “a method with incisions”

It is used if it is necessary to make a strongly rounded decorative element. This method is called “Curve Method”. For this, on the one hand, slots are made on the sheet. They can be done with a milling cutter or a sharp construction knife.

Cuts are made after 1. 5 cm. over, the more curvature, the more often you need to make slots. Cuts are made, leaving only 1-3 mm to the opposite part of the drywall. In order to fix the plasterboard sheet with slots, use putty, which is suitable for this material. Thanks to putty, the entire structure is more durable.

So, with the help of building tools and your dexterity, you can give the interior exclusive design and modern style. details about how to bend drywall, you can find out from the video.

Drywall cutting

In order for the process to pass quickly and without damage, it is necessary to take into account a number of features.

Cut on straight lines

Depending on the selected device, two main algorithms of work are distinguished.

The use of a knife

You need to use the tool as follows:

  • GKL is laid on a raise.
  • Marking.
  • To exclude the sliding of the blade, a guide is set along the line. It can be a profile or wooden rail.
  • With a knife, you need to draw along the marked border several times, and then break the sheet, pulling the smallest side with an effort down.

The knife is considered the most convenient tool for creating a direct and even cutcart cut, it is important to cut the part by more than 70%, otherwise the plate can crack so that the workpiece will be completely spoiled.

Advice! To exclude the hanging of the cut part on the cardboard, it is previously processed from the back side.

Using a jigsaw

To perform the process with your own hands using this tool, you need to observe a certain sequence of actions:

  • A sheet of material is placed so that the place that is cut is on the elevation, and both sections have stops. The saw should pass freely.
  • Marking.
  • If you need to saw in a straight line with the formation of extremely even edges, it is recommended to put emphasis. This role is a metal profile or wooden beam. The details are placed so that the base (leg) slides without delay. It is advisable to perform work in a respirator.
  • Putting a slight pressure on the jigsaw, it is directed in the right direction, focusing on the fishing line for the trimmer. For convenience, many devices are supplied with a laser pointer. To exclude defects, the electric tool must be completely adjusted.

The cutting of the GCL with an electrician does not require special professional skills, the main thing here is to choose the right cutting canvas if it is supposed to cut the product into small stripes or quickly form an even edge, then a special subcutaneous is suitable for the process. It has a P-shaped configuration, along the edges of which gear wheels are exhibited. They are fixed in the right position, and the pen plays the role of the limiter, determining the width.

Crinnine cutting

To obtain a more complex form, a jigsaw or manual saw for GKL is used. It is taken into account that the cardboard of moisture.resistant products should not have damage.

  • The sheet is placed on an even and solid base. Due to the need for sagging places of processing, rails are placed under the material that create the right elevation and emphasis.
  • The configuration is thoroughly drawn.
  • A jigsaw file is directed along the line at low speed. If you need to cut an element of the M-shaped shape, then the small area is first sawn, and then a large.

Without experience, accurate figurative cutting can only be performed with an electrician, or with a hand hacksaw. but it is long and hard to exclude errors, you must constantly check out with markings. Since it is hidden by the dust that appears, it is convenient to use a vacuum cleaner.

How to fix the profile on the walls?

For many, this is not a problem. Especially if we are talking about a new room with sufficiently even walls. Fasteners are carried out using standard oenic suspensions, the algorithm of action is as follows.

Step one. First, it is necessary to fix the suspensions to the walls using dowels.

Step two. Then the suspensions need to be bent to get the letter “P”.

Step third. Then a galvanized profile is taken and placed inside the suspension.

Step fourth. The latter has a special hole through which, using “fleas”, and you need to fix the profile.

Step fifth. Initially, the profiles are attached in most cases along the edges of the walls, then levels are aligned and pulled between them 3 threads. After that, the remaining elements are exhibited and recorded by the latter.

Actually, this is all. We recommend watching another thematic video that describes all the nuances of creating a frame for drywall sheets. Good luck in work and, according to the good old tradition, warm winters to you!
