An arch as an element of building architecture is intended to divide a room into zones without using a door. Recent years are marked active use these structural elements. Such an elegant device can enhance and decorate any home and save living space, which is especially important for small spaces. They can often be seen in hallways, kitchens and between other rooms. How to make an arch at home? To do this, it is necessary to study the features of carrying out installation work.

This covering can be purchased ready-made or made by yourself. The shape of such vaults is also different: starting from classic options and ending with modernist designs. In the process of their production, various building materials are taken: brick, stone, metal, wood, PVC, fiberboard, chipboard, gypsum board, plywood. The most popular are plasterboard sheets. They are flexible and easy to install.

Preparatory work

To understand how to make an arch, it is important to carry out installation one by one. First, the designated space is measured: its width and height are determined.

When starting to build an arc, it is worth considering the fact that the door plane will decrease by 10-15 cm. These indicators relate to height. Later, this space can be lined with decorative inserts made of ordinary foam plastic.

Its width is measured and divided by two. These numbers will be necessary to ensure that the traditional semicircle turns out smooth and symmetrical.

These data are equal to the internal distance corresponding to the opposite sides of space. At the beginning of the work, you should decide on the shape of the structure.

Traditionally, semicircular samples or gypsum board sheets are installed, which will be discussed below. Find out how to make an arch correctly below. To begin with, you should focus on the verticality of the surface, otherwise the design will look ugly and one-sided.

If the need arises, the internal plane should be leveled using plaster or putty, focusing on the installed beacons.

Installing Arch Facial Components

You can get an answer to the question of how to make an arch, starting with cutting out the façade structural elements. The main problem during this period is that you need to get two identical elements, regardless of the material from which the vault is made. Marking and cutting for each of them is carried out according to the same pattern.

You can make an even semicircle in different ways. For example, by using any devices. As such samples, you can take strong and elastic twine and a simple pencil.

1. The rope is tied to a rod.
2. The center of the circle is marked. To correctly determine the radius, you need to remember the number that was obtained during previous measurements.
3. So, if the width is 1 m, then the required figure will correspond to 50 cm.
4. 60 cm is laid off from one of the edges of the sheet and a line is drawn. The distance from the top of the opening to the top of the future arch corresponds to 10-15 cm.
5. The gypsum board is cut based on the width of the door plane. So, in this version it is equal to 100 cm.
6. Then, on the designated straight line, a border corresponding to 50 cm is marked on each side. These indicators indicate the boundaries of the hemisphere.
7. Using a pencil and string, 0.5 m of the length of the rope is marked and the last marks of the hemisphere are drawn. The result was an analogue of a homemade compass. As a result of using such a device, a circle with smooth edges is formed.
8. According to the markings, a semicircle is cut using a jigsaw or a stationery knife. Its width is 1 m and its height is 60 cm.

The profile for the arch opening is cut to obtain the required bend.

The arch is made in a different way using a long and flexible element. To do this you can take plastic panel, flexible plinth.

1. A rectangular base measuring 100 × 60 (65) cm is cut out. Next, 50 cm is measured from each side and 2 lines are drawn. The place of their intersection is indicated by a dot.
2. The drywall sheet is bent on both sides according to the width of the future opening. It turns out to be a semicircle. The volumetric part corresponds to the previously designated points, the ends should be in contact with the ends of the rectangular base in the lower part.
3. The finished vault is drawn and cut out.

The second method of making arches requires the involvement of an additional person. Taking accurate measurements alone will not be easy.

Erection of the frame on the arch

Make this one important element you can cook at home metal profile. Marking guides oriented to the width of the opening. Here these indicators correspond to 1000 mm. They are fixed on any side. They are secured to concrete and brick with dowel screws; for wooden surfaces, special self-tapping screws are used.

In order for the structure to be in the same plane as the wall, the frame should be fixed 12 mm inside the opening.

As soon as the gypsum board sheets are fixed and putty is applied, the base will become even.

Fastening is carried out on either side of both side parts of the frame. The length of such elements corresponds to 600 mm.

The bottom of the profile is cut at an angle. Fixing arch parts to the frame with self-tapping screws for metal bases.

Any owner of a residential building with an arched passage has somehow wondered how to design the arch so that it takes on a stylish beautiful view. In addition, it is necessary to maintain complete harmony general style premises.

As a rule, an arch is used to delimit space in the kitchen, living room, balcony, corridor and hallway. The design can take any shape, configuration and size, take different options decor.

How to paint an arched passage?

The photo of the arch in the interior shows the most popular way of designing the structure - this is initial plastering, then painting. This method Equally suitable for both classic luxury and super-fashionable modern styles.

Please note that first it is important to correctly select the base for the paint (the plaster itself), which is divided into several types:

• to create a relief effect;
• traditional putty;
• textured version of the composition;
• a special pigmented solution is applied.

First, before starting work, it is necessary to align the contours of the arch in the apartment as much as possible. For these purposes, plasterboard sheets, corners and putty are used. Joints and possible cracks should be filled with serpyanka. To obtain the smoothest and clearest contours of the structure, it is necessary to fix the corners with a profile.

Then you should ideally clean the work area evenly, applying paint using a roller. If you intend to further decorate the element with relief accessories, it is wise to immediately use a pigmented solution. After finishing the main work, you can introduce linings or decorative curtains into the opening.

Decoration with stone and tiles

No less in a relevant way beautiful design arch is decoration facing materials, which include: tiles, natural or artificial stone, imitation brick. Less often the opening is decorated tiles, or mosaic.

An important advantage this method serves to introduce arch decor into absolutely any style. The combination of stone can be completely different: with paper, textiles (wallpaper), plaster, paint.

When finishing an opening using this method, gypsum materials are usually used, but clinker and porcelain stoneware raw materials are not excluded. Due to their high strength and durability, they are usually located at the entrance to the house or on the balcony area.

In order to decorate an arch with stone, that is, its original cladding is of high quality and reliably serves its household, you need to make the surface perfectly flat, and then select a good, appropriate glue composition.

The cladding can be made with an individual non-standard pattern, so it is first recommended to apply markings for further precise orientation of the masonry.

You can also line the opening with natural, durable stone, but this will be a very expensive repair. Moreover, it is worth considering that the arch only needs to be in the opening load-bearing wall, or a solid partition.

The use of panels and stucco in the interior

Popular way of decoration door arch is framed with special decorative panels and overlays. The most relevant and relatively inexpensive material serves MDF, which harmonizes perfectly with classic style premises.

The surface is treated using artificial veneer or film. Please note that the simulation is under natural wood always remains at the peak of fashion.

To properly fix the panels in the passage, you should use special nails without heads and glue solution. There are situations when you have to remove the level, you should use a spacer and foam for installation. This process is practically no different from installing a door frame.

As in other methods, you first need to level the surface and eliminate all possible cracks and joints. Markets and specialty stores building materials offer ready-made options pads that lock into place with a simple click.

An interesting way to decorate an arch in an apartment is stucco, which is not at all difficult to do yourself using glue or liquid nails. Most often, polyurethane is used, which gives the interior a special gracefulness, chic and luxurious rich look.

Can be done relatively simple shapes, or to produce complex bulky cast parts. The main disadvantage of stucco is the rapid mechanical damage and failure.

Curtains and curtains

Since ancient times, an arched doorway has been decorated with ordinary curtains, but even now this design option, although less common, is acceptable. The entrance is masked with light tulle, a curtain or a thick curtain, which will serve as the door itself.

Usually, doorway disguised with bamboo curtains, beautiful threads, decorative beads. This method is very easy to do with your own hands, using a cornice above the opening to fasten the curtains. There are cornices of a curved configuration that coincide with the very shape of the opening.

It is no secret that the arch serves as a continuation of the wall, which is why, when designing it, it is necessary to take into account the decoration of the walls.

As you know, wood is the most noble and wear-resistant raw material, which is successfully used to decorate classical household items. It is better if the design is simpler, but very elegant in shape. Wooden arch It is also possible to hang it with an elegant curtain with gilding, which will successfully highlight the classics.

Lighting solution

The beautiful design of the arch is complemented by built-in lighting devices, which can be point, side or contour types. The easiest way is to integrate lamps into a plasterboard element at the end.

The decorative opening is equipped with recesses where light bulbs are subsequently installed. To slightly hide the backlight, you need to mask the recesses with glass. It is important to use colored or translucent glass, which in itself will serve as an additional detail of the interior and the structure itself.

The arch that divides the space of the kitchen and living room looks very beautiful, and its lower part smoothly turns into a bar counter.

Photo of arch design options

Arches are architectural element, existing since time immemorial. But despite all their archaism, arches are able to add zest to a modern one.

Now you can mount sheets of drywall - on both sides.

Construction of the arch vault

When starting to build an interior arch with your own hands, special attention should be given to the vault. Firstly, this is the most difficult part of the arch to manufacture, and secondly, its shape affects the entire structure.

In addition to the above-mentioned arch-portal, there are several more types:

• Classical arch or Romanesque(arch in the form of a semicircle);
• Arch in Art Nouveau style(half a circle cut by a chord. It is similar to the classical one, but with a flatter arch);
• Pointed arches(the vault seems to be made up of two circles that are leaned against each other);
• "Romance" arc(similar arches are made in very wide openings. The vault is in the form of two arches connected by a straight gap);
• Prism(the arch is made without any roundness, consists of straight lines, between which there are obtuse angles).

The sides of the vaults are also made of plasterboard. We cut out a recess of the required shape from the bottom of the sheets.

Since a prismatic interior arch consists exclusively of straight lines, it is easiest to make it yourself. To make a rounded vault, you will have to cover it in the lower part with bent sheets of plasterboard.

If you want to build an interior arch with your own hands, but have doubts about your own abilities, then you can use standard ones or make them to order. Arches can be chosen various designs, textures and materials.

Wooden arches will look expensive and presentable, but they won’t be cheap either. In addition, the material is heavy in every sense. For DIY work, fiberboard or MDF is better suited.

Assembling the arch must begin from the top.

First we use the wooden dowels supplied in the kit. We assemble a vault from two pairs of panels. We connect with PVA wood glue. After gluing, we wait for it to dry, and then the vault cornices from below.

Then we file the flexible plate of the inner part of the arch- with a margin of at least 10 millimeters.

We assemble the vault from the two halves, the halves are glued to the inner panel.

We install the arch in place and fix it with self-tapping screws or liquid nails. It is necessary to finish the side panels according to the dimensions of the openings with a small margin in length and width.

We also file the trims, from to to, so that the cut is inside the arch. Then we install platbands into the cornice of the vault using dowels. To do this, coat the groove with glue and insert the side panel into it so that the top edge is immersed in the groove.

We do the same with the second half of the arch.

An interior arch made of plasterboard is one of the most popular types of door designs today. This design of the opening can be done without special labor with your own hands. To do this, you need to know the basic principles of performing this work and understand the materials used. The rest is a matter of imagination and skill of the master himself.

Drywall is the most popular material for making arched structures

Advantages of a plasterboard arch

Making arches from plasterboard is so popular for a reason. Their prevalence in interiors modern apartments and houses is due to a number of advantages in comparison not only with standard door structures, but also with other materials used for such purposes:

• Appearance. Drywall allows you to create any shape and combine a variety of shapes in one product. In addition, it looks quite neat and is easy to further finish.
• Easy to make. Since the easiest way to make an arch is from plasterboard, many craftsmen prefer this material. It is easy to process and cut, and can be easily mounted on a frame. In addition, it can be bent according to the required pattern.
• Variety of finishing options. Finish options to give decorative look there is simply an unlimited number. This is possible thanks to the flat surface.
• Ease. Plasterboard sheets do not place excessive load on the supporting structures of the building.
• Durability. Such structures are quite durable and resistant to destructive factors.

The main advantage of a plasterboard arch is the ability to create non-standard forms of passage

A do-it-yourself plasterboard arch is a completely doable task. For beginners, you can get by with the simplest options, while professionals can create complex compositions inside the partitions.

Arches made of plasterboard are especially popular in the hallway, kitchen, living room or on the balcony.

Required tools and materials

Before you make a plasterboard arch with your own hands, you need to prepare everything necessary tools and purchase suitable materials. To create such a design you will need:

• jigsaw or hacksaw;
• tape measure and pencil;
• level;
• metal scissors;
• self-tapping screws;
• dowels;
• screwdriver;
• stationery knife;
• sandpaper;
• metal profiles;
• plasterboard sheets.

Basic tools for making a plasterboard arch with your own hands

Also, to make arches from gypsum plasterboard, you will need a metal base, that is, a frame structure. For these purposes, several options for special aluminum profiles are used:

• guide;
• rack-mounted;
• arched;
• reinforced corners;
• connectors for each type.

You can make an arched one yourself from a regular U-shaped profile by making cuts in increments of approximately 5 cm along the entire length. It is better to choose moisture-resistant plasterboard with a thickness of 12 mm, as well as ceiling plasterboard for the vault of the arch - 6.5 mm.

Types of profiles for drywall

Marking

So, to make a plasterboard arch in doorway, first you need to mark the parts. To do this, we outline the contours of the arch on the wall according to a pre-thought-out plan. Measure the height of the opening and determine its center point.

It is best to correct the data during the installation process. According to the obtained dimensions, the metal part of the structure, that is, the frame, is cut, and then the size is determined plasterboard sheets for plating.

To create an arch from plasterboard, you first need to mark the parts

Aluminum is cut very simply - using metal scissors. Drywall is cut by using a jigsaw along marked lines. This applies mainly to figured parts. A straight cut can be made using a utility knife. You need to make an even cut, going deep through the cardboard into the gypsum layer. Then place the material on the edge of the table and apply pressure to break off the element along the contour.

In some cases, it may be necessary to increase the space in the opening. In this case, you need to address this issue in advance and cut off part of the wall. For load-bearing structures, for example, in the hallway, there are restrictions. The secondary partitions can be completely demolished and formed in parallel with the construction of the arch.

By using a simple pencil The outline of the arch is marked on a sheet of drywall, then cut out with a jigsaw or a small hacksaw

Removing the frame

The shape of the future structure is created exclusively using a profile. The frame acts as a skeleton for the structure and holds all its elements. Let's look at how to form an arch from a profile.

Before making an arch from plasterboard, you first need to install guide elements in the doorway. For this, a corresponding U-shaped profile is used. It is screwed to the floor and ceiling according to a pre-designed design diagram.

Next, the base is made for the vertical frame for the future arch. The racks are driven into the guides and screwed with self-tapping screws. The metal arch itself is installed directly on top. You can create its shape with your own hands by bending the profile accordingly.

To create a frame it is used arched profile or cut and bent straight U-shaped

Cladding and finishing

Once the profile frame is ready, you can begin covering the structure. To do this, you need to cut the material into appropriately shaped segments. The front part of the plasterboard arch is removed from the wall sheets. It is important to take into account their thickness so that protrusions or depressions do not form in the future. general design walls.

Drywall is attached to the frame using self-tapping screws in increments of 10-15 cm. For internal cladding, use ceiling plasterboard. It is thinner, and therefore easier to secure and give it the desired shape.

Because interior arches made of plasterboard have a bend on the arch, the material is cut on one side and moistened with water so that it can be bent.

The main stages of creating a simple arched design from plasterboard

Next, you can start finishing. To do this, the corners are strengthened corner profile, and serpyanka is applied to the joints. Using putty, you need to cover all the cracks and places where screws are screwed in. After this, the surface is primed and completely puttied.

After the surface has dried and grouted, you can start decorating the opening. In the hallway it could be decorative stone or plaster, and in the living room - paint, wallpaper or MDF panels. Simple designs can be equipped with a box that suits the shape. But for complex options Finishing with putty and painting will be enough. Additionally, you can equip the arch with lighting. All wires are easily hidden inside the structure at the stage of creating the frame and cladding.

Starting a large-scale cosmetic or even major renovation With a complete change in the interior, owners often want to bring many interior design ideas to life. One of them may be to transform an ordinary rectangular doorway into an arched one. If you figure out how to make an arch from plasterboard, then you can easily install it yourself.

An arch can affect the structure of everything design solution interior, and an additional decorative overlay of a certain style will set the design of the entire room.

Having studied detailed instructions for the installation of the arch, having prepared everything necessary materials and tools, it is quite possible to make an arch from a rectangular doorway in just one day.

It should be noted that an arch made using the same technology can transform not only a doorway, but also wider passages that divide large rooms into zones.

Materials and tools for making and installing arches

In order to bring a boring doorway into a new state and get a neat, aesthetic arch, you need to prepare the following materials:

• GKL plasterboard sheet with a thickness of 9 ÷ 12 mm.

• Galvanized metal profile or wooden beam for making a frame.
• Metal perforated corner for strengthening the joints of drywall planes. Fiberglass mesh is also suitable for this process.

• Self-tapping screws for fastening drywall and perforated corners to metal profiles.
• Gypsum-based putty - rough (starting) and finishing.

To carry out installation, the following tools must be available:

• Electric jigsaw and drill.
• Ruler, square, tape measure and pencil.
• Grinding machine or metal scissors .
• Screwdriver.
• Construction knife.
• Roller with metal spikes.
• A flexible strip that will help create an even arch shape.
• Spatula and grater for working with putty.
• Sponge, water container, thick soft fabric(you can use an old terry towel).

Taking measurements and preparing structural elements

• Before you start manufacturing arched elements, it is necessary to take measurements of the opening where the arch will be mounted. Its width and the required vertical distance are measured, from top to bottom, on the side walls of the opening. These parameters will determine how rounded the arch will be.

In addition, it is necessary, based on the thickness of the drywall, to determine the depth of its installation, since it must be fixed at the same level with the plane of the wall - it must be recessed deep into the doorway.

• You need to step back from the corners of the doorway to a distance that will be equal to the thickness of the drywall and make appropriate markings by drawing installation lines for the frame profiles.
• According to the obtained parameters of the opening size, using a grinder or metal scissors, pieces of the metal profile are cut - two for fixing horizontally and four for fixing on the side walls of the doorway. They are installed along previously marked lines, leaving space for drywall.

• If the walls of the opening are made of brick or built of concrete, holes are drilled into them using a drill (perforator) directly through the metal profile in the wall, into which plastic dowels are driven into which the fastening screws will be screwed.

The plasterboard parts will be attached to this structural element - the frame.

• The next step is to mark and cut out two plasterboard panels using the previously obtained dimensions. They must fit exactly into the door opening between the walls.
• Next, on these panels you need to draw and then cut out two arched parts from them. In this case, you need to act very precisely, since if you mark the arc incorrectly, you can easily get an ugly arch skewed to the side.
• Curvilinear "trajectory" cutting, that is, the arcuate part of the arch itself can be marked in different ways, and all of them are equally accessible.

First way

The marking is carried out as follows:

— First, the panel is laid on a flat horizontal surface.

— Then, along the upper horizontal and on both vertical sides, the thickness of the metal profile, already fixed in the opening on the walls, is marked. Usually it is 50 mm. Straight lines are drawn along these points, parallel to the edges of the panel;

— To draw a semicircle, take a pencil and a piece of non-elastic cord, which is tied to the pencil so that it rotates freely in this loop.

A homemade “compass” applies the required arc of the arch

A self-tapping screw is screwed into the center of the circle. Then a cord is attached to it, so that the sharpened pencil lead falls at the intersection point of the previously drawn lines parallel to the left and right edges with the bottom edge of the panel. The result is a kind of compass, capable of drawing circles of the required diameter in this case.

The markup can be transferred to the second panel simply by copying it from the first.

Second way

For the second method of marking a line arched arc You will need a flexible plastic bar, a pencil and two pairs of hands.

— First you need to determine what height the curved part of the arc will have at its highest point. To do this, the bar is placed in the door opening between the profiles fixed to it. One end of the bar must be attached to bottom edge of the profile, fixed on the side left wall of the opening, its highest point on the bend should touch the middle point of the horizontally fixed profile, and the third point of contact of the plank will be bottom edge of profile on the right wall.

— At the last point of contact with the profile, a mark is made on the bar - it will determine the length of the very arc that will determine the curved section being cut out.

- Next, the same thing is done on the drywall panel, where, just like in the first option, 50 mm are already marked along the edges. One of the masters holds the bar so as to align its beginning and the mark made with the lines, and the second draws the border of an arched semicircle along it.

— Then, the marked area is cut out with a jigsaw.

Third option

The third option is a template of the arched section made on hard cardboard according to the dimensions taken from the door. It can also be marked using a homemade “compass” made from a cord and a pencil.

— Ready template placed on a plasterboard panel, outline its outline with a pencil, and then cut out the part to be removed with a jigsaw.

— The template will not allow you to make a mistake and the semicircle will be perfectly even.

The next step is to prepare a metal profile for the curved parts of the frame, onto which the lower part of the cut plasterboard panels will be attached. To cut the required length of the profile, you can use the same flexible strip on which the length of the arc that forms the arched vault is marked.

You need to prepare two such sections of the profile. Then cuts are made on them using metal scissors or a grinder, thanks to which it will be easy to bend the profile into an arc with the desired bending radius.

It should be especially noted that if the arch has a small thickness, then sometimes one wide metal profile with made on him cuts to secure to him two panels on both sides. The profile must be recessed inside the arch to the thickness of the drywall used, since later the lower bar of the arch will be attached precisely to this curved part of the frame.

The remaining elements will be in the course of installation work - usually there is nothing to do with them special difficulties does not arise.

Installation of the frame base of the arch

Metal frame made of galvanized profile

• Installation of the arch begins with the installation of plasterboard elements with cut out semicircles that are fixed in the doorway to metal profiles screwed into it.

To secure drywall, use special screws and a screwdriver.

These elements are fixed on both sides of the doorway.

• Next, with inside The cut and bent metal profile is screwed onto the cut arched opening. When carrying out work, you need to hold the profile with one hand, pressing it exactly in the shape of the arch.

This part is screwed first to one side and then to the second.

• The frame will not have the proper rigidity and completeness of the structure if it is not installed between the metal arched elements of perpendicular sections of the profile. They will tie the plasterboard walls of the arch together. These jumpers are installed in several places in the arched structure.

To secure the jumpers to the profile, self-tapping screws with wide heads and a sharper nose are used.

Installation of a wooden arch frame

If making a frame from a metal profile seemed too complicated a process, then you can mount it from wood.

• To do this, you need to prepare bars measuring 20 × 20 mm - for fixing on plasterboard, and 30 × 30 mm - for fixing on opening walls.
• Next, an arch is marked on the drywall, cut out, and then inner surface elements are screwed wooden blocks with ends located in a circle.

• It is left along the edges of the part free space, 30 mm in size, which will be occupied by the bars installed in the doorway.
• The walls of the doorway are marked in the same way as when attaching a metal profile, only instead of it, 30 × 30 mm bars are fixed along the markings
• Then, the prepared arched panel is placed in its “standard place” and screwed into the opening to the wooden blocks installed in it.

You can do it differently - fasten the bars to the edges of the drywall, and then screw the finished stasis panel to the wall. But in this case, it will not be very convenient to work, especially when the second panel with an arch is attached, since it will be difficult to climb between the two arched elements with a hand with a screwdriver.

Cable routing

Before proceeding to the manufacture and installation of the lower part of the arch, electrical cable, if lighting is provided in the opening.

The contact ends of the cable are fixed to the metal profile approximately in the place where the point pins should be installed electric lamps. It is best if the cable is enclosed in a plastic corrugated pipe to avoid accidental damage to the insulation from the sharp edges of galvanized profiles.

When the prepared bottom strip of drywall is installed, it will perfectly cover all the ugliness of the wires.

Manufacturing and installation of the lower plasterboard panel of the arch

When the frame and front parts of the arch are installed, you can proceed to making the bottom strip, which will cover the entire unsightly appearance of the frame.

First, the total length of the arched bend of the arch and the width of the distance between the installed arched frame parts are measured with a tape measure.

The dimensions are transferred to the drywall, and a rectangular strip of the required dimensions is cut out of it.

Next, the plasterboard strip needs to be bent into an arch; however, the material is hard and fragile, so it can easily be broken, ruining the part. In order for the process pr went smoothly, you can use two methods to bend this material:

1. The prepared part is marked along its entire length into transverse strips 50 mm wide.

• Next, cuts are made along the marked lines, approximately half the depth of the drywall.
• Then the part is carefully bent and immediately, without delay, screwed to the metal profile, which is located inside the arched structure.

Video: an easy-to-make plasterboard arch

2. The second method of bending drywall, in principle, is still easier than the first, but it will take a little longer, since you will have to wait for the material to take the desired shape.

First, a needle roller is passed over the plasterboard strip with force, which pierces with its sharp spikes top layer cardboard

If the master does not have such a roller in his arsenal, you can use a sharp construction knife - with it, cuts measuring 20 ÷ 30 mm are made on the surface of the drywall, at a distance of 15 ÷ 20 mm from each other, both in length and width.

The next step is to moisten the panel on the side of the punctures with water using a sponge and lean it against the wall, placing the long side vertically.

After about 15 ÷ 20 minutes, you will be able to see the first results - the panel will begin to bend under its own weight. Then the part is wetted again and left for another 40 minutes.

For the perfect bend of the arch, you can specially knock down a structure from three boards in the shape of the letter P (a kind of conductor) with the dimensions of the place in the doorway where the arch will be installed. Then turn it over, placing it on the horizontal part.

Next, in the same way, having moistened the plasterboard piece with water, it is laid on the legs of an inverted letter P, wetted side up. After 20 minutes, its middle will begin to sink into the structure. Then, it is wetted again and left for 40÷ 60 minutes for complete subsidence to the horizontal lintel of the structure.

By the way, a similar method of bending a plasterboard strip sometimes allows you to make an arch without a frame at all, as shown in the attached video:

Video : giving bending a plasterboard arch

The still wet drywall is placed on the metal profile using self-tapping screws, which are screwed in at a distance of no more than 100 mm from each other.

The next step is to cut holes in the designated places on this part of the arch, into which, after finishing, it will be possible to install spotlights(if their installation is provided).

Having made the holes, you need to pull the cables located inside the structure to them, but you should not completely pull them out of the holes, since the protruding ends of the wires will interfere with finishing.

Arch finishing

Having completed the installation of the frame and sheathing, you can proceed to finishing the arch with putty. Only by covering all the seams and recesses from the screw heads with putty mixture and leveling it can you get a neat arch.

The puttying process is carried out in three stages:

— the first layer evens out deep flaws;

— the second — displays the even shapes of the arch;

- the third layer is the finishing layer, and with its help the ideal smoothness of the surface is achieved.

• However, before taking on the putty, it is recommended to strengthen the corners of the arched openingspecial perforated corner, which will easily take any curved shape.

Instead of corners, you can use fiberglass mesh, but it will not give such a clear, smooth and reinforced edge as a corner can provide. The corner is installed using self-tapping screws, which are screwed in at a distance of 150 ÷ ​​200 mm from each other.

• Next, you can move on to working with .

For work with drywall, acrylic or gypsum-based putty is used, intended for interior work.

The acrylic composition can be purchased in ready-made paste form, while the gypsum mixture is sold in dry form. construction mixture. Knead it immediately before use. This is best done using a mixer attachment that is attached to a drill.

You need to know that you can’t knead right away large number putty, as it sets very quickly, so it must be prepared in small portions. The packaging of the building material must contain instructions, which must be carefully studied to find out exact time“life” of the prepared composition and complete drying of the plastered surface.

• The first step is finishing the joints of drywall and the main walls of the doorway.

The work is carried out using wide and medium-width spatulas. With one of them, putty is applied to the joint, and, as far as possible, smoothed, comparing the surfaces of the drywall and the doorway.

• Having sealed the joints between the drywall and the wall in the door opening, you can immediately close the screw heads on this part of the structure with putty. When carrying out this process, you need to remember that the surface must be perfectly flat, so it is necessary to achieve exactly this effect. For this stage of work, you can use a metal trowel, which will immediately cover a large area.

• The first layer is used to seal deep joints between the drywall and the wall. Here it is very important to distribute the putty into all the recesses and chips, since it is necessary to bring the seams on the same level with the wall and arched structure.

Do not apply too thick layers of material, as wet putty can quickly separate from the wall surface. It’s okay, if necessary, you can put four layers of putty instead of three - they will stick much more securely than two or three very thick ones.

• Applying putty to all wide joints before it dries, a reinforcing fiberglass mesh should be placed on top. This easy-to-use material can be purchased in any desired width, so there will be no problems with strengthening wide gaps.

The required length of mesh is measured from the reel, and using a spatula, this tape is then pressed into the putty, stretched and leveled.

• The arched bend, trimmed on both sides with a perforated corner, also needs to be treated with a layer of putty, comparing the surfaces.

If the junction of two drywall planes is arched doorway reinforced with fiberglass mesh, if necessary, it can be cut in some places, since it should lie perfectly flat on the surface, without waves or folds.

• When all the seams are sealed and reinforced with reinforcing materials, the first layer is left to dry.
• After it has dried, go over the surfaces with medium-grit sandpaper to level the dried putty. By doing this, you need to try to “knock down” all the sharp protrusions so that they do not interfere with further work. But, at the same time, the structure must be processed extremely carefully so as not to expose the reinforcing elements.

Aligned joints must be thoroughly cleaned of dust using a damp sponge.

• Next, you can move on to the second thin layer of finishing putty, which should cover and level all surfaces.
• After it dries, the entire structure is cleaned with fine sandpaper (about 220 grit).

Before applying the third layer, you must again take measures to clean all joints and smooth surfaces from putty dust.

The finishing layer should form the arch “cleanly”

• The finishing coat should give a smooth finish. The putty is applied in a very thin layer, and in this case, a ready-made pasty material made on an acrylic base is best suited.

During the work process, it is necessary to smooth out all marks left by the spatula.

• Having finished, the structure is left to dry for at least 8 ÷ 12 hours. The level of dryness of the material can be determined by its color - it should lighten to pure white.
• Next comes the grinding process, and it is better to carry it out with a special grinder, onto which fine-grained sandpaper (grain 280 ÷ 400) is fixed, and then a soft polishing cloth.

Sanding is carried out until the surface becomes perfectly smooth.

• After the arch is sanded, you can paint it, if this was planned. After painting, special built-in installations are installed in the doorway

Making and installing an arch is not such a complicated process. The main thing is to understand the little things, how each stage of the work goes, and having understood all the nuances, you can purchase materials and get down to business.
