How to make an arch in an apartment. DIY arch in your home. Shapes of arched openings and their capabilities

How to make an arch with your own hands? This question worries many who dare to design the interior opening on their own.

A door arch made with your own hands will make you proud of yourself, thereby allowing you to add something original and unique to the interior of your room or bedroom. Despite the fact that many beginners are tormented by vague doubts, in fact there is nothing terrible in this work, the main thing is desire. If you have it, ours detailed plan help you get the job done!

What is an arch and its varieties

The arch is an ancient architectural element that is increasingly used as an internal decorative element input or interior door, or rather a doorway. An arch is a universal opening in a wall that can give “volume” small room, and at the same time, zoning the apartment into a small area.

Taking into account the wishes of homeowners, thanks to arches, designers can turn various ideas into reality, giving the doorway different kind. Today modern materials allow you to give the arches different geometric shape, and also form intricate vaults. Most often for the manufacture of arches and their cladding they use:

• Brick.
• Wooden beam.
• Plywood.
• Tiles.
• GKL, etc.

The structure of the arch is a support for partitions and walls. But, since the doorways in high-rise buildings are not load-bearing, the only requirement that is put forward to them is to withstand their own weight (with finishing finishing material). If the wall is load-bearing, the material must be selected according to external loads.

Any version of the arch, which is mounted instead of a door, performs a purely decorative function. The frame of the structure can even be made from a lightweight profile for fiberboard or chipboard; you can also use wooden beams. Only important point– reliable fixation of the partition so that the decor does not fall off or become deformed after a few days.

As we noted, the design of a house can be beautifully complemented with an arch, because there is a huge variety of its forms. They can be made in a classic or romantic style. Art Nouveau is also often used. No less popular are the ellipsoidal shape, trapezoid, “portal” and many others.

The first example is made as a regular semi-arch, in the shape of a semicircle. On last photo you can observe a square interior opening called a “portal”. This design method is carried out with strict adherence to rectangular outlines. All other samples are intermediate variations between the two basic forms.

But these are not all options. You can also experiment with side supports, use curved posts, etc. You can finish the form and decorate it in different styles, the main thing is that the passage fits harmoniously into home interior. In some apartments, classics and a round, correctly bent vault look great, in others - portals, it all depends on the taste preferences of the owners. Pay attention to the advice of experienced finishers:

1. Classic arches are best done in apartments with high ceilings, at least 3 m.
2. In panel-type high-rise buildings, it is better to frame the doorway in the Art Nouveau style.
3. It is preferable to decorate wide doorways from the corridor to the hall in a romantic style, for which wide counters are selected.
4. The finishing of the “portal” opening goes well with the interior of the room, which uses clear lines. “Portal” is ideal for houses made of lining, logs or timber. This combination is very elegant and harmonious.

What materials can be used to form arches?

To make an arched vault, you need to stock up on the following material:

• Sheets of drywall.
• Plywood.

It is worth noting that it is best to sheathe the frame with sheets of plasterboard, because in the future it can be decorated with different decorative materials. But, if you need to create a more sophisticated shape, choose plywood sheets as they bend better. The preparation of the arched frame is formed from:

• Metal profile.
• Wood beams.

But, to build an arch, you can also take concrete, aerated concrete and brick, which are decorated with finishing materials. Despite the fact that such structures are solid, it is prohibited to erect them in high-rise buildings due to their heavy weight. It is also prohibited to make door frames from metal, which, moreover, will cost a pretty penny. And how to make an arch in an apartment with your own hands from metal? After all, this is a very labor-intensive process that requires the use of specialized devices. That is why plasterboard is the most acceptable material for finishing apartments.

How to make an arch from wood?

Do-it-yourself wooden arch, more precisely wooden frame, is formed without much effort. But, in addition to wood blocks, you will also need sheets of plywood. The first thing to do is measure the width of the passage, subtract the thickness of the materials, after which we get optimal thickness wooden beams. Then an arc is drawn on the plywood, which is cut out with a jigsaw.

Subsequent installation is carried out with self-tapping screws (5cm), which secure the beams to the plywood. Arch in doorway It is also fixed with self-tapping screws, which are screwed in at a distance of 15 cm. The final stage– fixing the 2nd wall of plywood and its subsequent covering with sheets of plasterboard. Please note that you need to fix the drywall sheets with special self-tapping screws for working on drywall.

Installing a plywood arch

How to make an arch with your own hands from wood without using natural material? Today this is not difficult, because wood can be replaced with plywood. To correctly calculate the amount necessary materials, including fittings, the first thing experienced finishers do is create a sketch.

To work with plywood, you will need the following handy tool:

• Jigsaw (or hacksaw).
• Drill.
• Screwdriver.
• Sandpaper.
• Finishing equipment.

Since plywood is enough unique material, which allows you to create original and unusual shapes, you need to work with it, following the step-by-step instructions:

1. Measure the doorway and note what size the arch will be.
2. Then you need to cut the strip and carefully process it.
3. The resulting strip is slightly moistened and left for some time.
4. After these manipulations, the plywood will be pliable and will easily take the desired shape.
5. The prepared strip is bent in the required way and immediately inserted into the required doorway, carefully fixed and spacers installed in the corners.

Forming an arch from plywood. After the canvas is installed, you need to wait a little until the sheet dries completely and takes its final form. At the next stage, you can act in two scenarios:

• Form inserts from wooden blocks and cover the surface with plasterboard.
• Take advantage polyurethane foam, filling the voids with it.

Installation of a plasterboard arch

Working with plasterboard, as with plywood, is very similar and does not cause difficulties, but is cheap. If you have the opportunity to build walls and form an arch at the same time, this way you can complete the work as quickly as possible. Before forming an arch, you need to prepare the surface step by step, namely:

• Dismantle the old one door panel, decorative overlays, platbands and other accessories.
• Repair all damage to the walls to avoid troubles in the future.
• Get some tools.
• Draw up a detailed work plan and sketch.

You can install a plasterboard arch in different ways; below we will describe each method in more detail. The first option is the most popular:

• Take 2 sheets of drywall, one of which is cut in half.
• A U-shaped frame is formed in the doors using a metal profile.

• One segment is fixed to the frame, having previously been marked into 2 equal parts and marking the center.
• A hole is drilled in the rail from the edge and in the center. The distance between them should be equal to the middle of the arc of the formed arch. To do this, determine what distance will be maintained between the edges of the semicircle.
• Then a curved line is drawn to connect the hole in the middle of the batten with the center of a piece of drywall sheet that is fixed to the frame. You should immediately check whether the height of such an opening is suitable.
• Then the sheet is removed and the excess is cut off, after which it is fixed again on the frame.
• The second sheet of drywall is installed on the opposite side. Taking a corner and the first segment (like a stencil), transfer the dimensions of the arc. Next, cutting out the arc and fixing it is repeated according to the same pattern.
• After the work has been done, a void is left in which the frame is mounted. To do this, the profile is cut and bent. The resulting structure is fixed to the racks and drywall. It is also worth installing jumpers for the reliability and strength of the structure.

• Next, cut out the required strip, bend it, and make deep cuts on the inside. You need to fix it without haste, with careful movements.
• That's all, the arch is formed. All that's left to do is to paste the wallpaper or paint it in the desired colors.

The second method is much more complicated. The masonry is formed using the following technology:

• Drywall pieces are fixed from the corners on both sides using a mixture of PVA glue and water.
• Drywall is cut so that each next fragment is smaller than the previous one.
• Work continues until the smallest fragment is installed.
• Self-tapping screws or anchors are used as additional fixation.

It's just preparatory process. Further it will be even more difficult. The next stage will require plaster and putty. Large expansions and other defects are sealed with plaster, and a smooth arc is created with putty. This is quite painstaking work that requires firm and experienced hand masters, so it is better for a beginner to immediately purchase template blanks.

Step-by-step instruction

If you decide to install an arch in the hallway, kitchen or balcony, follow the recommendations below:

• Remove the old door and trim.
• Widen the doorway to the desired size.
• Level the walls and repair any defects.
• If the structure will be backlit, carry out the wiring.
• Take all measurements in different places to minimize errors.
• At uneven walls choose the depth of the arch at the thickest point.
• Don’t be too lazy to make a life-size sketch (this will allow you not only to install the arch as accurately as possible, but also to pre-assess what the arch will look like).
• Start installation work load-bearing frame need in this order:
• Create a main contour from the profile around the perimeter of the doorway and fix it on the wall.
• Secure the frame system.

• Install the vertical guides with an indentation from the plane of the interior surface to the thickness of the drywall and add 2 mm to the data (make a reserve for plaster).
• The surface must be rolled out with plaster until it is as even as possible.
• To create a semicircle from the profile, cuts are made on it in increments of 5-7cm.
• When an ideal curve is formed from the profile, it is installed in Right place and fixed to the frame.
• For greater strength, the arc must be fixed with several hangers to the horizontal upper guide.
• Then the crossbars are installed in increments of 40-60cm.
• The result should be a structure made of metal profiles in the shape of an arch for further cladding.

Finishing

When the arched frame is ready and sheathed, you can begin finishing work. To do this, you need to cover the edges and joints of the materials with specialized paper tape or fiberglass mesh. You will also need to apply putty in at least 3 layers and sand the structure. Once you are convinced of the reliability of the formed structure, you can proceed by following some of the recommendations given below.

To do everything Finishing work, need to purchase acrylic putty, which is intended for interior works. But, please note, it is better to use a special mass for drywall. Before use, the putty mass is thoroughly stirred until smooth.

When starting work, put on gloves and other equipment. personal protection! The putty is applied in linear movements with a rectangular spatula. In addition to filling all the unevenness and joints of materials with putty, it must also be applied to the heads of the screws so that their edging does not show through. Similar actions are carried out until the surface becomes ideal.

After puttying, you can begin gluing the joint and edges to remove all sorts of irregularities and give the material strength. To do this, you can take a fiberglass mesh or paper tape, it all depends on your preferences (both options are good). Cut a piece of mesh and place it at the joint (in the very center), pressing it with your fingers into the putty that has not yet dried. Check that the tape is securely fastened and that there are no wrinkles.

After all the joints have been treated with mesh, you can cover the curved parts of the arch with it. The work needs to be done according to a similar scheme. When the mesh forms folds during the processing of arcuate sections, they can be straightened by cutting the fabric sharp knife.

After drying, the putty will become snow-white. This will be a signal that you need to take sandpaper and go smooth the surfaces. But, work carefully, do not remove too much putty, so as not to expose the mesh. For this work, use a respirator, because during surface grinding there will be a lot of dust, which is very harmful to human lungs.

When all 3 layers of putty have been applied and the surface has been cleaned, you need to wait about 12 hours for the structure to dry completely. Work again sandpaper fine grain, achieving a perfect surface. That's all, you can decorate the surface.

Decorating the arch

It doesn’t matter at all what material you used to install the arch, because even a do-it-yourself brick arch needs final decoration. For decorating the door arched vault You can use the following methods:

• Painting to match the walls.
• Sheathing with wood blocks (as an option, laminate, siding, etc. are often used for this).
• Wallpapering.
• Use fake diamond based on gypsum.
• Decorate the structure with mirrors or mosaics (for mosaics you can use small pebbles, corks, glass, etc.).
• Use foam molding or surface painting.

Important! Try not to overdo it, so as not to clutter the aisle and mix incompatible items. It is worth noting that sometimes it is enough regular painting to add elegance.

As you can see, there are a lot of options for finishing decoration, for which you can use not only natural materials. It all depends on the designer’s idea and the wishes of the owners, as well as the general style of the room. The classic additional interior can be complemented with stucco molding and fabrics so that everything fits harmoniously together. The finishing of the columns looks no less laconic if clinker is glued to them.

Ready-made arch kits

If you are not sure about own strength, and the educational video lessons from the Internet are not entirely clear to you, you can make your life significantly easier by purchasing ready set to form an arch. Similar kits can be made from different materials, have different design, color, design and texture, which will allow each person to find the most suitable option. The most suitable option is a set made of fiberboard or MDF. Such materials are very similar to wood, but are less complex to process and install. In a ready-made standard kit interior arch enters.

How to make an arch in a doorway? This question interests many owners of apartments and private houses.

It should be noted right away that an arched opening can only look ideal in rooms with high ceilings.

With low ceilings, such a structure visually significantly reduces the opening. Therefore, you should think carefully before deciding to build an arch. If you accept it, then you can find a lot of materials to implement your idea.

Methods for constructing arches

How to make an arch instead of doors? Today there are such ways to create arches:

1. For an arched opening, the wall is hollowed out according to pre-made markings. This method is more suitable for rooms with not very high ceilings.
2. If the ceiling height is sufficient and doorways their upper part is sealed with pieces of plasterboard or plywood to give them an arched shape.

When chiseling a wall proceed as follows:

1. You need to remove all decorative finishing including door frame.
2. From the floor itself, a vertical line is marked on both sides of the opening to the height of the future arch. For accurate markings, use a level or plumb line.
3. The width of the marked opening is measured and divided in half. The result is the radius of the arch.
4. The center of the arch is marked on the upper horizontal line. A screw, self-tapping screw or nail is fixed to this point.
5. A strong thread is tied to the screw, the other end is attached to a pencil. The excess thread is wound around the pencil, leaving a length equal to the radius arches
6. A mark is made on the vertical line from the center point downwards at a radius distance.
7. A semicircle of the upper part of the arch is outlined.
8. On the other side of the wall, the marking operations are repeated.

Now you can start chiseling using a hammer drill or other tool. The choice of tool depends on the wall material. It is recommended to drill as much as possible along the intended contour more holes. They will help in the chiselling process. IN wooden wall The opening is cut out with a jigsaw or a hacksaw with a narrow blade. Final stage preparatory work– processing the edges of the resulting opening and decorating it with prepared materials.

At high ceilings do door arch It is possible if you follow this sequence of actions:

1. The frame of the future arch is assembled in the opening from wooden or metal profiles.
2. Marking is done on drywall or other material from which rectangles need to be cut. Their width is equal to the radius of the arch, their length is equal to the width of the opening. Using a large compass or thread and a pencil, the upper arcs of the arch are marked and cut out with a jigsaw.
3. The resulting blanks are attached to the frame with hardened self-tapping screws. Their caps are recessed 0.5-1 mm into the drywall.
4. The end of the opening is sealed. This can be done using fiberboard. This material bends quite well. You can use a strip of plasterboard 8 mm thick. It is rolled several times with a needle roller and sprinkled with water. Punctures are made to a depth of up to half the thickness of the drywall sheet.
5. If there is no needle roller, punctures can be made with an ordinary awl. The distance between them is about 1 cm. They are made only on the side where the part will be bent. After some time (after about 1-1.5 hours), the plaster gets wet and the strip bends quite easily. It is better to bend it on a wooden or plasterboard template. After drying, it becomes hard again.
6. Drywall is puttied and the arch is decorated at your discretion.

Arch configurations

An arch in a house gives the rooms a certain personality. Configurations and forms arched openings there are quite a few. Let's look at some of them:

1. The classic version is suitable for rooms with a height of 3 m. Arch correct form has a bend radius of 45 cm or more. If you add it to the height of the doorway, then the total height of the room may simply not be enough.
2. The Art Nouveau arch is often erected in standard apartments. Its radius exceeds the width of the doorway, so there are angles between the vertical elements and the arc. They can be made sharp or rounded.
3. Romantic style is an arch option for large openings. There can be a horizontal insert between the rounded corners, or it can be installed at an angle.

The configuration of the arch depends on the desire and aesthetic taste of the owner of the home. An arched opening can be wavy, polygonal, illuminated, with various niches and shelves, with stained glass windows and so on.

Materials for arch equipment

The arched opening can be made from monolithic concrete, plastic, brick, metal, wood, chipboard, fiberboard, plywood, plasterboard sheets and other materials. When using brick, concrete or stone, their weight must be taken into account. Such structures may require a special foundation and reinforcement elements for connection with the walls.

Metal is a material that fits into any style. But not every metal is suitable for these purposes. Option from of stainless steel is very expensive. Galvanized iron in interior spaces doesn't look good. It is quite difficult to make complex figures from metal.

Wood is a beautiful natural material. It requires virtually no additional finishing.

Drywall, wood fiber and particle board. These building materials can be finished with plaster, painted, covered with a layer of decorative or ordinary plaster, paste over with wallpaper, veneer with decorative stone.

Plastic is a material that is easy to process. Plastic structures are not required additional processing and finishing.

To decorate the arches, they also sell ready-made designs from different materials.

1. The appearance of the arch should correspond to the overall design of the room. Each side of the opening can be designed differently.
2. Any work on the construction of arched openings begins with dismantling door frame.
3. For convenience and to speed up the marking process, it is recommended to use a full-size template. It can be made from cardboard.
4. When constructing curved frame elements from metal profiles, slots are made on them that allow the workpiece to be bent. The slots are made in increments of about 5 cm.
5. For work, a drill or hammer drill, a hammer, iron scissors and a hacksaw are usually used. Sometimes other tools may be needed.
6. The frame is attached 10-12 mm deep into the doorway so that the drywall attached to it is flush with the wall after puttying.
7. The assembled structure is sanded and puttied. You can cover surfaces and corners with fiberglass mesh.

Reading time ≈ 8 minutes

If you need to renovate your apartment, then perhaps you will need information on how to make an arch, and do it yourself at home beautifully and correctly, without the help of builders. Recently, such interior elements have attracted more and more attention. The door is removed, and the opening itself is designed in the form of an arch, which can have a wide variety of, sometimes bizarre, shapes.

Arched doorway of unusual shape

Apartment options for arched openings

Owners can pursue several goals: to create common space, expand the room, create a light and elegant design, and so on. Worth buying if you want finished arch in the construction department, as a last resort - put in a little effort and devote a little time to create an original and interesting option, which will definitely be exclusive.

The arch has gained extraordinary popularity

To improve the passage from room to room without using a door, it is not at all necessary to call a hired team of craftsmen. By choosing the right type and format of the building, you can easily do everything yourself. It is equally important to wisely choose the materials that will be used to create of this element. The step-by-step instructions below will tell you how to do everything as correctly as possible and avoid common mistakes.

Different types of arches have some differences in design, which affects their further installation. The main differences lie in the supports of the structure.

It is worth noting that interior openings are not load-bearing. Therefore, it is important to choose an arch based on the appropriate parameters.

Beautiful arch between rooms

The arched opening, which is used instead of a regular door, is made of several materials. Now we're talking about specifically about the frame of the entire structure:

• metal profile on which they are mounted on top plasterboard sheets(GKL);
• wooden blocks with a cross section of 20-30 mm.

This type of arch will easily hold its own and total weight along with the finishing. Here the main task- reliable and rigid fastening to the walls. This will protect the elements and remain in place in their original form for more than one year.

If we are talking about a private house or apartment, then the arch open type used only as a decorative element. But the entire load-bearing load in this design option is transferred to the side concrete walls or a lintel over the structure itself.

Possible types of arches and features of each of them

Before you make an arch with your own hands at home, you need to choose a form of construction that will look beautiful and correct in the future. The most common forms are:

• classical;
• romantic;
• modern;
• ellipsoid;
• trapezoidal;
• portal.

Strict arch portal

Arched doorway classic shape is based on a regular semicircle. But the portal arch consists of strict outlines rectangular shape. Other varieties are derivatives of these two main varieties. In addition, there can be asymmetry using only one support on the side. Or the form may be completely unthinkable.

The most common form of openings

The choice of shape and finish of the future arch should be chosen based on the overall design of the room, so that it fits harmoniously into the interior. For example, a semicircular arch will fit perfectly into. The following parameters must initially be taken into account:

• ceiling height;
• dimensions of the doorway;
• individual features of the apartment.

You must understand that one living space looks great with a classic arch, and a portal will harmoniously fit into the second. But here it all depends on the personal preferences of the owners.

Arch in Art Nouveau style

1. A classic arch will look great where the ceiling is over 3 meters high.
2. Art Nouveau design - perfect option for panel apartment building and design of the entrance to the kitchen;
3. A romantic with wide supports frames the entrance from the corridor to the hall well;
4. Portal structures fit into the interior with clear lines (both vertically and horizontally). They are well suited for installation in beautiful houses from wooden beam or logs.

Material selection

To quickly create an arched opening, you can buy a ready-made kit for creating an arch in the store. But this option is not suitable for everyone due to quite high price. Yes and appearance they are not very different from each other. However, the selection the desired model may reach a dead end due to the difference in the parameters of the opening and the future structure.

The main components of the arch

Most often for self-made purchase the following materials:

• drywall;
• plywood sheets.

The winner is drywall, which has light weight and quite easy to use. Another advantage is that plasterboard sheets are easy to finish with many finishing materials. And plywood lends itself better to bending.

Finishing an arched doorway

To create the frame part, use:

• wooden blocks with a cross section of 20*20 mm and 30*30 mm;
• metallic profile.

Alternatively: you can create similar designs made of brick, concrete, aerated concrete. The only thing left to do on top is to give it a neat appearance. But not everyone will like it. After all, such an interior is an indicator of wealth and status. It is also necessary to take into account the weight of such a structure. If the floors are old and fragile, then this type of arch should be folded back.

Metal frames are rarely used not only because of the additional weight, but also because of their considerable cost. If you want to build an arch complex shape, then you must understand that doing this on your own will be very difficult. To construct an arch with your own hands, it is better to choose drywall and a suitable profile.

Step-by-step creation of an arch with your own hands

Below are photos and step-by-step descriptions the whole process, with the help of which it will be much easier for you to make your masterpiece in the doorway. Initially, you need to take care of creating the frame part. And only after that start covering it and finishing. The main thing is to be as attentive and careful as possible. Then your idea will be realized in the best possible way.

Plasterboard arch (diagram)

Before you begin installing the arch, you need to properly prepare the doorway.

1. Door leaf and frame old door needs to be removed.
2. Expand the opening to the dimensions required for installation work.
3. You should not plaster the cut walls on which the structure frame will be installed. In any case, they will be blocked by the casing. You just need to align the edges and dismantle the pieces of old building materials(plaster, concrete particles, falling bricks).
4. The main task is to create a base and securely attach the frame to it. In this case, it is required that he be in vertical position. Tilts are not allowed.
5. If the arch will have lighting or backlighting, then the wiring is carried out before installation work begins.
6. Measurements are taken not at one, but at several points of the opening. When the walls are not perfect, you should choose the widest part of the opening. This will be the width of the structure.
7. A template on cardboard will help make markings easier. This way you can identify what is necessary and avoid making mistakes. Moreover, you will be able to see on the spot what the future arch will look like.

Important! Don't forget that the arched opening at the top absorbs about 15 cm of the total height. Minimum distance between the arch and the ceiling should be 20 cm. This information is entered during preliminary calculations.

The arch reduces the height of the doorway

Construction of a load-bearing frame - important stage, because it will support the entire arch structure.

Fastening the sheathing to the frame

To bend drywall, use dry or wet method. For the first one, you will need a jigsaw to carefully make the cuts. For the second, it is better to use a needle roller to quickly and evenly wet the panel. Using self-tapping screws, the cut out elements of the arch are installed in their places. The final stage is plastering and finishing with the selected material.

Finished arch

You now know how to make an arch with your own hands at home, and you can design it beautifully and correctly. The main thing is to use your imagination and choose, but do not forget to follow the dimensions and assembly instructions exactly. And in the video below you will find the entire process of creating an arch.

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

Arch markings

A significant disadvantage of this design is the reduction in the size of the doorway. To see whether the arch will fit well into a specific doorway, it is better to first cut a blank from paper or cardboard and secure it above the door. If the opening height 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 bending radius

To draw the upper part of the arch on the workpiece, we will use compass. You can make it from available materials: a self-tapping screw or an awl fixed in the center of a circle, thread and a pencil. By evenly pulling the thread, we draw the required arc. The longer the thread, the flatter the arch will be.

Constructing a circle

You can also make a compass from a scrap metal profile.

Drywall cutting

1. First, cut through the first layer of cardboard and the gypsum core. To do this, apply a ruler to the intended line and draw along it several times. sharp knife or metal file.

Cutting through the first two layers

2. To finally break the gypsum core, place the drywall on its edge and lightly tap the cut area. If the part being 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 the drywall, use a sharp knife to remove 45° chamfer.

Chamfering

Cutting blanks for the upper arch of the arch

It is most convenient to work with jigsaw or a special plane for drywall. Using 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.

Cutting with a jigsaw

Trim curly edges it is possible with the help drywall knife saw-shaped or metal files with fine teeth. However, this will require some skill. A knife or file 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 cut area with a hammer and, if necessary, run the knife over it several more times.

Cutting with a drywall saw

Then it cuts through back side sheet, on which traces of pressure from 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, to install lamps or sockets), you can use an electric drill with a crown-shaped attachment.

Drill bit

Cutting and bending metal guides

Aluminum guides are cut using conventional metal scissors. To attach the upper part of the arch you will need a special arched profile. You can buy it in a store or make it yourself.

To bend the profile, they are made on it cuts. 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 the cuts will have to be made only on one side.

Profile bending

Drywall bending

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

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 plasterboard blank should be rolled before bending. needle roller.

Before bending, the workpiece is rolled with a needle roller

Next the sheet is evenly moistened with water and placed on a curved surface that follows the shape of the arch, pressing down with a weight. 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 taken into account 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. This can be done quickly with a grinder, however, since this creates a lot of gypsum dust, it is better to do the work outside.

Dry bending of plasterboard

Frame installation
