Do-it-yourself one-sided arch step by step instructions. Do-it-yourself drywall arch

taking away swing doors, the owners increase the usable area. The device instead of them drywall arch - the easiest and most affordable option.

Types of arched structures - choose for your apartment

Plasterboard arches create the most different shapes, which differs mainly in the upper part. Many styles have been developed - from the simplest to the most complex. We will focus on those that even people without special skills can do. Having mastered the basics of creation arched openings, you can move on to more sophisticated designs.

One of the popular styles is classic with a strict top shape. This is a semicircle with a radius equal to half the width of the doorway. It looks good in an apartment of sufficient height when the doorway is at least 2.5 m. Suitable for any interior, but best use- entrance to the kitchen or a long corridor.

close to classical style portal, only has a strict rectangular shape over the entire height. Ideal option for wooden houses, apartments with clear horizontal and vertical lines. Right angles in this design look elegant. Often give additional originality to wooden decorative elements threaded.

The style of the classic semicircular arch is practically preserved in the elliptical one. Her set is carried out different heights. Formula: the height of the vault is half the width, does not apply. Ideal for apartments with low ceilings.

An even more simplified vault is characteristic of the romantic style. The masters gave her the name "with rounded corners." The shape allows you to create designs of large width and relatively low. Ideal for decorating the passage to the balcony connected to the room.

The top of the Art Nouveau arch has a small radius of curvature, a sharp transition at the junction with the vertical parts. Looks good in rooms simple design. Often installed instead of a door to a balcony or office.

Trapezoidal shape attracts supporters of non-standard design. The asymmetrical interior arch also emphasizes the original taste of the owners. A popular form of recent times is the semi-arch. One side of it is semicircular, the other remains straight. Fits in modern styles minimalism, hi-tech, art decor.

The form and design must comply overall design. The width of the arch, the height of the room are taken into account. Before making the arch, we determine the parameters, especially those relating to the radius of curvature. Classic is suitable for apartments with ceilings from three meters. For arches in place of standard doorways, rounded corners are recommended. A wide opening is best designed in modern style.

Tip: to visually evaluate how door arch fit into the interior, make a template and apply to the doorway.

Preparation - project, materials, opening, installation of profiles

We start with a project that we draw to scale. We outline the location, the type of arch. Specify dimensions and that's it distinctive features. Even better, make a template that will help for further work especially for a beginner.

In the work you will need tools: a puncher with a drill, a screwdriver or a drill, a jigsaw, a drywall knife, a hammer. For measurements, you need a tape measure, a level. We fasten everything with self-tapping screws, if the opening is brick - with dowels. We purchase UD and CD profiles from materials. For wooden frame you will need pieces of timber. We buy drywall for ordinary rooms simple, for places with high humidity- moisture resistant.

Next, we prepare the doorway: we dismantle the canvas and the box. Depending on the intended size, you may need to expand the space. Plastering the sidewalls is not worth it: everything will be covered with sheets of drywall. We remove the exfoliated plaster, align the side parts. We do not achieve an ideally vertical state: it is important that the sidewalls are more or less even for reliable fastening of the profile rails.

If we plan the backlight, we bring the wiring in advance. On the uneven walls the depth of the arch is determined by the greatest thickness. All measurements are carried out in several places, so as not to be mistaken. The arched arch takes up to 15 cm, and the distance to the ceiling is required at least 20. Do not forget about this when calculating and marking the arch.

We cut two pieces of a metal profile along the width of the arch. Four more will be needed for the sidewalls. Their length is equal to the height minus the thickness of the profile rail. For installation on concrete or brick wall we make holes with a perforator, install dowels, fasten the profiles with self-tapping screws. For fastening to wooden walls we do without dowels, we use self-tapping screws 50 mm long.

We retreat from the plane of the wall to a distance equal to the thickness of the drywall. For plaster, add another 2 mm. After 50 cm, we install reinforcing crossbars that reach from below to the place where the upper arcuate piece of drywall will join the sidewalls. To fix the arcuate element, you will need to install additional profiles, but at this stage we do not mount them. We have a base to which we will attach the skin.

Mounting an arch is the main way to create any structures

For some reason, for many, the arcuate part causes special difficulty. You can read a lot of instructions for its manufacture with calculations and formulas. Maybe math lovers use them, but in practice everything turns out much easier, you don’t need to remember the school course.

We take a piece of plasterboard, equal in width to the doorway, from which we will cut an arc. You need a straight line, better wooden lath, at one end of which we drive a carnation. On the sheet we find the middle, draw a line. For a classic arch, from the second end of the rail, we also drive in a carnation at a length from the first, equal to half the width of the arch.

Along the centerline, we retreat from the top of the sheet so that the top nail is at its edge, and the bottom one is pressed into the drywall. We have a kind of circle. We take the planks by the top and draw a semicircle, leaving a trail from the top stud. We have outlined the dimensions of the upper part of the classic arch. If you need an oval one, move the lower point down along the axis, as much as you want to reduce the height, and outline the cut line.

Cut out the arc along the outlined outline. We do this with a drywall or metal file. You can use a jigsaw, but there is a lot of dust from it. An uneven cut, which may turn out, is leveled with sandpaper, ensuring that the curve comes out in perfect shape.

We perform further actions in the following sequence:

1. Using self-tapping screws, we fasten a rectangle with a cut-out arc to the frame. On the opposite side, we temporarily screw the same one.
2. We take a square, apply it to an unmarked sheet and draw points with a pencil that correspond to the cut out arc. We make them larger in order to draw the most accurate curve on them.
3. We remove the cut of the sheet and draw a line along the points. We cut off the excess and set the second arc to a permanent place.

A copy of the first arc should not be made: asymmetry is not ruled out, so installing a second sheet with an absolute match of the contours is problematic.

We take a trowel so that its width is enough for two sheets, and align them. Then we set profiles between them. They need to be bent. We make cuts on the sidewalls with scissors, bend, adjust in place. We fix it with screws to drywall, holding the rail with a bar so as not to injure our fingers. We expose the back of the profile rail at the same level with the edge of the arcuate element.

Having attached both strips, we install jumpers between them. We cut the profile into pieces with a length that is 1 cm less than the depth of the arch. In the places where the jumpers are attached to the installed profile, we cut out the sidewalls from the inside and install the prepared fragments. Jumpers give the necessary rigidity.

Next, we mount the sidewalls on both sides. The arc also needs to be closed with drywall. To do this, you have to bend it. To the ignorant, this may seem impossible, because they are convinced that the standard GKL is both fragile and rigid - it does not want to bend, it breaks. How to give it the desired bend, speech ahead.

Drywall technology - how bends are made

For surfaces with curved lines, there is thin drywall. You can buy a sheet and set the required segment. But the logic turns on: why buy a whole, if you need a small piece, which is full of purchased sheets standard thickness? In general, everything is correct: a thick sheet can also be bent.

Usually used simple and fast way. The cut-to-size workpiece is laid on a flat surface with the right side up. We take a square and after 10 cm across we draw lines with a pencil. We make cuts along them, approximately ⅔ of the thickness. The square is not mandatory, but desirable: along the parallel, the bend will turn out to be of better quality. For arches with large bends, this method is most suitable.

We turn the workpiece with cuts up, apply it to the arch. We fix the upper part with screws. From the center we gradually move to the end. We screw in the screws every 10 cm on both sides. The effort required is small, the sequence is mirrored. We do everything gradually, slowly, then the GKL will bend almost perfectly.

For those who do not like or do not know how to plaster, another method is recommended. Indeed, on drywall, curved according to the previous method, you will have to apply more than one layer of plaster. A very steep bend in the proposed method, which is called wet, is difficult to obtain, but possible. Its advantages are that the bent fragment remains intact, it is not necessary to mask the damage with plaster: a regular finishing layer is applied.

You will have to buy a roller with needles and make a template for bending. No special skills are required, but the process is lengthy, technological breaks must be observed. We do it as follows:

1. Cut out semicircle templates from a fairly rigid material. We install them vertically and fasten them together.
2. Sheet of drywall the right sizes lay on a plane and roll with a roller. Moisten with water, but not too much so that it seems slightly wet.
3. After 10 minutes of exposure, put the workpiece on the template - the non-rolled side from the bottom. The workpiece itself begins to sag, we carefully help, without applying excessive effort.
4. We wait about half an hour until moisture is felt to the touch. You don’t need to wait any longer, it can dry out and brittleness will return.

Plastering and design - we give the product a complete look

The frame sheathed with plasterboard is a semi-finished product, without quality finishes at the finish line it was better not to start. Many do not like this stage - it is better to cut, drill, fasten than to deal with mortar and sandpaper. Yes, the work is not easy, but necessary, since they undertook to do everything with their own hands.

First, apply a primer and let it dry. Those who ignore this step, wanting to save money and time, are wrong. It is the primer layer that allows the plaster to adhere securely to the surface and not be torn off over time. We use acrylic putty, but it is better to apply a special one for drywall joints to the seams. It is more durable, does not crack later.

We close up joints, possible defects on drywall and self-tapping screw heads. We try not to apply a lot of putty, otherwise you will have to remove it later. We pass with a spatula, taking away the excess. To hide irregularities, to give strength, to prevent cracking, we glue the joints with fiberglass mesh. We impose segments of the desired length on fresh putty. We make sure that there are no wrinkles. If it doesn't line up, it's best to tear it off and try again.

We glue the bend of the arch with a mesh. There are bound to be wrinkles here. To eliminate them, we cut the mesh in these places and glue it. Immediately apply the second layer on the grid. We wait until it dries: it will turn completely white. sandpaper smooth surfaces. Do not overdo it: the grid should not be exposed. If this happens in separate places- undesirable, but not terrible.

We clean from dust and apply the next layer over the entire surface. Again, we wait until it dries, and we grind, but with paper with a finer grain size. Finishing layer apply on a thoroughly cleaned surface. We are waiting for a long time for the putty to dry well. The next day we are engaged in grinding, using the finest sandpaper.

Sometimes it is enough to paint the arch to give it a finished and elegant look. But many want to achieve originality using the following techniques:

sheathed with wood or plastic;
paste over with wallpaper, veneer;
use artificial stone trim;
decorate with mirrors, mosaics;
decorate with stucco, columns;
arrange lighting.

You can use any option, the main thing is harmony with the general style.

The interior of a living space can be monotonous and boring, as most apartments are built according to standard projects and resemble one another. You can add variety and originality to your home by replacing the standard doorway with a more elegant and aesthetic arch.

Knowing how to make an arch in an apartment, many experts assure that all work can be done independently using inexpensive building materials.

Benefits of the arch

The best way out is a drywall arch, as this construction material very popular, you can find it in any store and even choose the one that will be more suitable in your case according to the main characteristics. In addition, it is easy to process, bend and does not require special tools for cutting.

For the manufacture of the arch you will need drywall different thickness- the one that will be on top may be slightly thinner than what will be placed below. Besides facing material, you will need a metal profile of two types - guide and rack.

The profile frame will make your arch more durable and reliable, which is important when we are talking about a frequently used room. You will also need self-tapping screws designed for working with wood, and large dowels.

Where is the best place to make an arch

The arched opening is relevant in the hallway or in the kitchen - places where you do not often need to close the doors. However, these rooms are among the most frequently used rooms, and therefore care must be taken to ensure that your arch has stood for as long as possible.

It should also be noted that the cladding will take up some space, and the opening will decrease in size, so if the doorways in your apartment are not very high, there may be big problems with the work.

After the material is purchased, you can proceed directly to the workflow itself. To make it easier for you to make an arch with your own hands and to avoid mismatches, you need to carefully measure the opening.

Width, height and wall thickness of the original object are key factors. After that, you can start cutting drywall. The most difficult thing is to cut a semicircle for the upper edge of the arch.

Step-by-step instruction

To do this, you can use the old proven tool - a cord and a pencil. Take the width of your doorway and add about 20 centimeters to it, and then cut a strip of drywall to that size. After the layout is ready, mark a point in the center of the base, stepping back from the bottom edge of just a few centimeters.

At this point, the end of the lace is fixed. Most often, for reliability, it is fixed with a bolt or nail. A pencil is tied to the other end. The distance between the fastening of the first end of the rope and the pencil is half the width of your doorway.

With the help of this simple device, we draw the correct arc of the desired size and cut out the arched opening along the resulting line. There should be two such templates, since the arch must be drawn in two directions. The second template is much easier to cut using the first one instead of a template.

Further, talking about how to make an arch in an apartment, you need to take care of correct installation and profile fixing. The guide profile must be placed at the top, making sure that it exactly follows the contour of your arch.

The result obtained must be strengthened with a more rigid rack-mount profile. Dowels should be used to fix the profile.

Working with drywall

It should also be noted that when fixing drywall, the surface of the product will rise slightly, and if you want your arch to merge with the wall, it is better to set the profile a little deeper, stepping back from the outer edge of the opening a few millimeters inward.

Further, the cut out templates are fixed on the profile. The work is done using self-tapping screws, and the heads of each screw should be slightly pressed into the surface so that when final finishing there were no problems. To fill the space between the templates, you need to use a strip of drywall, pre-treated with moisture.

This will give the material sufficient flexibility and in places of a semicircle it can be easily leaned against the profile. You can apply moisture with a good rag, you can use a roller.

After that, you need to wait a few hours before the drywall dries and comes into the right state for fastening. The width of the strip should be the same as the width of the original opening.

final touch at self-manufacturing arches is the putty of the seams and the finishing of the finished arched opening. For these purposes, there is a special drywall putty, which is more delicate to handle. It lays down in a thin layer and hides all the external flaws of the "raw" product.

The arch can give the room a more elegant look, enliven the atmosphere and make your apartment stand out from a number of other typical buildings. If you do all the work with your own hands, you can take into account all the subtleties, and the result will be as accurate and functional as possible in your conditions.

Photo tips on how to make an arch in an apartment with your own hands

Starting to repair an apartment or house, people strive to make their home as comfortable, stylish and elegant as possible. One of the most popular design ideas is clearance doorway in the form of a semicircular arch. Having studied the technology, it is quite possible to make an arch from GKL with your own hands.

Using an arched structure, you can influence the design of the entire environment and set the tone for the arrangement of the entire interior.

Constructions arch type are used not only for doorways, but also for the zonal division of the corridor. In this article, you will learn how to make an arch from GKL with your own hands.

Necessary tools and material

From the tools you will need a screwdriver, tape measure, construction square, pencil, spatula, grater, container, knife, sponge, drill, jigsaw, metal shears.

Draw the outline of the arch on the drywall. To draw the top arched structure use a homemade compass from a self-tapping screw screwed into drywall and a thread with a pencil tied to it

The greater the length of the thread, the greater the radius of the arc. Here you have the opportunity to experiment until you get the shape of the arch you need.

The blade of the tool must cut through the material strictly according to the markup - the quality of the arch directly depends on this. Next, start creating the arched frame. It can be metal or wood. Both options have their merits: aluminum profile characterized by evenness and lightness, and the tree is distinguished by great strength.

If you have a concrete wall, then you first need to make holes with a drill, insert dowels into them and only then screw in the screws.

Then, after attaching all the profiles to the wall, start the installation of the plasterboard. Sheets are installed using a screwdriver. The size of the screws depends on the thickness of the drywall.

Fasten the curved aluminum profile along the edge of the drywall. This will increase the rigidity of the structure. First, attach both ends of the curved track to the metal frame, and then screw the drywall sheets to it. You need to screw in the screws in increments of 0.1-0.15 m.

Mount perpendicular pieces of the profile to connect the side walls of the arched structure to each other.

Fix the lower arched arch section. Using a tape measure, measure the length and width of the arc. Cut out the appropriate piece from the gypsum board. Attach it to the bottom of the arch, gently bending to give the desired shape.

The edges of the drywall rectangle should be flush with the walls of the arch. Fix the section with self-tapping screws on both sides of the arc. Read from the center of the arch.

Inspect the resulting design and eliminate minor defects. Proceed to finishing. Tape the edges of the drywall with fiberglass mesh or paper tape.

Apply putty (minimum 3 coats). Sand thoroughly with a grater. The arch is ready. It remains only to paint it.

Varieties of arches

Exists different types drywall arches. They usually differ in the configuration of the top, and in some cases in the way they are connected to the vertical segments.

The photo of drywall arches shows that they are usually divided into six types:

Classic.
Modern.
Romance.
Ellipse.
Trapeze.
Portal.

Also, a semi-arch is separately distinguished.

It is not so difficult to make and mount an arched structure yourself. You just need to study the technology and choose suitable design drywall arches. We wish you success.

For interesting interior apartments can be selected East style, which is distinguished by its unusualness and beauty. And quite often, as an element of this style, do-it-yourself interior arches are used, which home craftsmen can also do.

classmates

The arched doorway gives the room some freedom, as well as an increase in space. Therefore, many people use this type of finish, performing these works after the completion of the main repair. At the same time, you can use different materials, which allows you to make the interior arch more accessible to any person.

What is needed for work?

It will not be possible to build an arch with bare hands, so it is worth preparing necessary tools, without which it would be impossible to do. In any case, you will need:

hacksaw
hammer and scarpel
tape measure and pencil
ladder
liquid nail gun

Regardless of the material used, the listed tools will make all the work much easier. In addition, the speed of work, as well as their quality, will be much higher than when working without using a power tool.

Materials for interior arches

For such an interesting design, which, of course, is the arch, you can use various materials. In addition to wooden arched structures, plastic interior arches, which are produced in factories, are quite popular today and are put on sale already in ready-made. But this is not the only material that is used during the renovation of apartments. are also quite popular with the population, especially since they are able to repeat any form. The use of other materials is allowed as a finish of the arched structure, which allows you to get unusual and interesting options internal interior.

Opening preparation

Before starting the manufacture and installation of the arched structure, it is necessary to prepare the doorway. For this you need to remove door leaf and dismantle the old door frame that was part of door block standing in the opening.

To get a semicircular upper part of the doorway, you need to round the edges of the opening itself. This can be done using a frame, especially in cases where drywall will serve as the finishing material.

Note!

For wooden structure a frame is also needed, which must be made of wood.

These works need to be done at the next stage of creating an arched structure.

Arch frame

Before you make an arch with your own hands, you need to do work on the device of its base. For drywall arches, metal profiles are used for the frame. To make the base even, and both sides the same, you can prepare a template that will completely copy the final shape of the future design.

The profile itself must be prepared for bending. This can be done by cutting the side elements of the profile, after which it can be bent in any radius. The more cuts you make, the rounder the opening will be. It remains only to fix all the elements on the wall.

What can be used for fastening?

To do metal carcass for an arched structure, it is necessary to have nails that fasten the guide profiles. But to connect the profiles into a single structure, you need to use self-tapping screws with a press washer, which have a flat and wide cap, due to which they allow you to fix all the profiles with each other much more firmly.

To tighten the screws, a screwdriver is used, on which a bit with a cross slot is installed. The type of slot is selected depending on the configuration of the self-tapping screw, so when buying the necessary nozzle for a screwdriver, you should also take a self-tapping screw with you, which will need to be tightened.

Wireframe creation

Finished items

Interior arches made of wood also require the installation of a frame, on which everything will need to be fixed. wooden details arched structure. To work with wood, you need to prepare a jigsaw or a sharp hacksaw. This is necessary in order to qualitatively and accurately cut, varnished or laminated, finished parts of the future arch.

Quite often in stores you can find cashing for arched structures, which has a groove on the inner surface into which you can insert any part ready for use. For example, an addition for door frame, which has sufficient rigidity, and at the same time has an attractive appearance.

cutting drywall

When the frame is fully prepared, you can begin to sheath it with plasterboard sheets. To do this, you need to arm yourself with a hacksaw or a jigsaw to cut out two identical elements of the opening. If a template was previously made to facilitate the assembly and installation of the arch frame, now it can serve as a model for the side details of the future arched opening.

Use a pencil to mark the cut line. In order for the door arch to be as even and symmetrical as possible with your own hands, it is necessary to use a template, which can serve as a door frame, if there should be installed in the opening arched door. If there is no such template, then you need to cut out one side part of the arch, and cut the second part along it.

Frame sheathing

Drywall installation

The side parts of the arch are ready, which means it's time to install them on the frame of the opening. To do this, use self-tapping screws with fine threads, the length of which is 35 mm. During the tightening of the self-tapping screws, you need to carefully monitor the force of attraction of the self-tapping screw to the drywall sheet.

Note!

If it is exceeded, then the self-tapping screw will pass through drywall sheet and the mount will not be reached.

After completing the installation of the side parts, it is necessary to close the space that was formed after their installation. To do this, you need to take the size of the width of the opening and measure its length. You can cut the insert for the arched opening with a simple knife. But the edges of the insert must be processed with a planer so that they are even and neat.

How to bend drywall?

After the drywall part is cut out, it must be installed in the interior arch. But installing even drywall on the bend of the arch can damage the part being installed. Therefore, before installation, it must be bent. Only in this case do-it-yourself interior arches will look stylish and beautiful.

In order to bend the drywall element, it is necessary to slightly moisten it with water. After it dries, there will be a slight bend naturally. Once this happens, you can begin to install this element in place. Curved drywall will freely accept new form, which has an arch frame. It remains only to produce finishing a new section of the interior space.

Plasterboard sheathing

Puttying, painting, gluing

The finished arch must be given an attractive appearance. To do this, it must be puttied and painted with paint to match other interior items or covered with wallpaper. The corners of the arched structure need to be reinforced. This can be done using a special paint corner, which, due to its design, takes the form of any corner.

The corner is installed on the applied putty, which is used to putty the entire surface of the interior arch. After installing the corners, the arch is puttied again, and after it dries, they start grinding. Finishing stage will be painting the entire structure or full or partial wallpapering. This is how the installation is done interior arches with their own hands and their subsequent finishing.

The doorway will look more aesthetically pleasing if you arrange it in the form of a semicircular arch. You can make it from drywall yourself, without resorting to the services of professional builders.

arch markup

A significant disadvantage of this design is the reduction in the size of the doorway. To see if the arch will fit well into a particular doorway, it is better to first cut out a piece of paper or cardboard and fasten it above the door. If the height of the opening is less than 2.5 m, it may be necessary to reduce the bend of the arch or make small bends only at the corners of the arch.

Installation of an arch with a small bend radius

To draw the upper part of the arch on the workpiece, we will use compass. You can make it from improvised means: a self-tapping screw or an awl fixed in the center of the circle, a thread and a pencil. Pulling the thread evenly, we draw the required arc. How more length threads, the more gently sloping will be the vault of the arch.

Construction of a circle

You can also make a compass from trimming a metal profile

cutting drywall

1. First, cut through the first layer of cardboard and the gypsum core. To do this, a ruler is applied to the intended line, and a ruler is drawn along it several times. with a sharp knife or saw for metal.

Cutting through the first two layers

2. To finally break the gypsum core, drywall is placed on the edge and the cut is lightly tapped. If the part to be cut has a small width, you can break the plaster by simply pressing on the edge of the sheet.

Cutting the second layer

4. To remove roughness along the edge of the cut, it is processed sandpaper or rasp.

Important! For perfect joining of sheets along the edges of drywall with a sharp knife, remove chamfer 45°.

Chamfering

Cutting blanks for the upper vault of the arch

It is most convenient to work with electric jigsaw or a special planer for drywall. With the help of them, you can cut out any shapes from drywall. Moreover, with this method, gypsum practically does not generate dust, and the resulting edges require almost no additional processing.

Jigsaw cutting

You can also trim curly edges with drywall knives saw-shaped or metal saw blade with fine teeth. However, this will require some skill. A knife or a saw is drawn along the intended line so that the blade penetrates as deeply as possible into the sheet. In this case, the tool must go strictly perpendicular to the surface. Next, tap the place of the cut with a hammer, if necessary, draw a knife over it several more times.

Cutting with a knife-saw for drywall

Then cut through back side sheet, on which traces from the pressure of the knife are already visible. Then the excess pieces are cut off, and the edges of the sheet are trimmed with sandpaper. If the cut line is large enough, it is better to cut the sheet inside the outline into segments.

For getting holes(for example, for mounting lamps or sockets), you can use an electric drill with a crown-shaped nozzle.

drill bit

Cutting and bending metal rails

Aluminum rails are cut with conventional scissors for metal. To fix the upper part of the arch, you will need a special arched profile. It can be purchased at the store or do it yourself.

To bend the profile on it are made incisions. The distance between them depends on the bending radius - the larger it is, the more often notches should be made. For bending, it is better to choose an L-shaped profile - it will be much easier to work with it, and incisions will have to be made only on one side.

Profile bending

Drywall bending

For the device of the arch can be purchased arched drywall . It is more plastic and, since its thickness is less than ordinary sheets, it bends easily. However, buying a whole sheet is quite expensive. Some stores sell such material not in sheets, but in segments, which is very convenient. If it is not possible to purchase a small piece, you can also bend a regular drywall sheet.

Thin arched drywall bends easily but costs more

To do this, you can use two methods: wet and dry. In the first case, in order for moisture to better penetrate deep into the sheet, the drywall blank should be rolled before bending. needle roller.

Before bending, the workpiece is rolled with a needle roller

Further sheet evenly moistened with water and put on curved surface, repeating the shape of the arch, pressing down with a load. A device for drying the workpiece can be cut from the remains of drywall or plywood.

wet bending

Important! With any bending method, it should be noted that drywall bends well only along the length of the sheet.

At dry bending cuts are made along the entire length of the fold. Moreover, the larger the bending radius, the more often such notches should be applied. You can do this quickly with a grinder, however, since this produces a lot of gypsum dust, it is better to do the work on the street.

Dry bending drywall

Frame installation

After dismantling the door frame, the surface is cleaned of loose plaster, dust and dirt and all irregularities are knocked down. Further, on the sides of the doorway, with the help of self-tapping dowels in increments of 20-30 cm, they are fixed two rack metal profiles. At the same time, 11-12 mm should be retreated from the edge for the installation of drywall and the application of putty. If the width of the opening is large (more than 1 m), fasten between two guides jumpers. Small sections of profiles connecting two side rails are also mounted at the bottom of the opening. They should rest on the floor.

At the top of the doorway are mounted two curved profiles. If necessary, they are also interconnected by jumpers.

Fixing the top part of the profile

Fastening the profile with jumpers

Between themselves, the sections of the profile are fastened with self-tapping screws.

Drywall fixing

The very first self-tapping screws with a step of 25-35 cm blanks for the upper semicircle of the arch are attached. Their width should be equal to the width of the doorway plus 10-15 mm. Self-tapping screws should not be fastened too close to the corners - it is necessary to indent 1-1.5 cm, otherwise cracks will appear at the attachment points.

Drywall installation

Corner fixing

Important! So that the screws do not protrude above the surface, they should be sunk into the sheet by a couple of millimeters. In the future, the holes from them are covered with putty.

The finished structure is plastered with a wide spatula first starting, and then finishing putty. The solution is applied to inside arches, and then, after it is completely dry, on the side walls. At the joints of drywall, to protect the mortar from cracking, it is attached with a putty paint grid.

After the installation is completed, the arch is covered with putty

Attaching the paint grid
