How corners are formed during plastering work. Plastering corners: step-by-step instructions Which perforated corner is best for plastering slopes

External corners must be aligned and strengthened during the repair process, for which it is necessary to use perforated corner ok different sections. Today we will talk about attaching a painting perforated corner to an external plaster or plasterboard corner, and also clarify the stages of work and the materials necessary for this.

Materials and tools

The corner has a central stiffening rib and side strips with perforations, which help the element to be securely fixed on the edges of the outer corner. You can attach the corner to gypsum plaster or starting putty, as a rule, a putty mixture is used for fixing to drywall, and gypsum is used for fixing to plaster plaster composition. External corners are not only vertical angles at the junction of two walls, but also cuts ceiling structures from plasterboard, as well as window and door slopes.

Instructions

To work, in addition to a corner and material, you will need metal scissors, a spatula and a level. First, the perforated element is cut to fit sharp corner from the edges with scissors, then a small amount of Rotband or “Start” putty is mixed and installation begins.

When fixing to a gypsum plasterboard corner, a minimal amount of putty is required; it is applied with a spatula along the edges of the outer corner, the corner is applied to the base and pressed tightly. The remaining mixture that has made its way through the perforation is removed. In this case, you can do without a level, because the gypsum boards are attached evenly and there is no point in doing the same job twice. With perfectly even corners of gypsum plasterboard structures, the corner is fixed with a stapler.

When attaching a corner to plaster, most often the corner needs to be trimmed, so the gypsum mixture is applied with thicker strokes, the corner is applied without pressing and only then pressed with a level until it is completely leveled vertically. Since in some places of the outer corner the corner protrudes above the surface of the side walls by 3–4, and sometimes by 5–7 mm, then after fixing the pit element on the wall, it is necessary to cover it with a plaster mixture using a 40 cm wide spatula.

Putty and plaster for attaching the corner should be mixed only in a plastic bucket, first pouring water into it and then adding the dry mixture and kneading it with a mixer. The consistency of the mixture ranges from “thick sour cream” for gypsum plasterboard and gypsum board to liquid plasticine for plaster corners with large differences.

Conclusion

In conclusion, we note that in addition to painting corners, there are plaster corners, which, instead of perforation, have a rigid mesh on the sides; they are used only in plastering works, fixing directly into the body of the solution at the corner and plastic elements for curved corners.

Below you can watch a video on attaching a perforated corner.

Designed to securely fix corners of walls, ceilings, floors, etc. With its help you can give the room a beautiful and smooth appearance. And then, when starting further repair work, it becomes much easier for the master to decorate the room with various materials.

• Using a perforated galvanized plaster corner, you can make different geometric shapes - circle, oval, square, etc.

Thanks to the corner, work happens faster and better.

From the article you will learn:

• Slopes using a corner
• Application for arches
• Cost of corners

About the use of perforated corner

If you decide to level and finish the walls yourself, but have never done this before repair work, then you simply need a perforated galvanized plaster corner. Every master knows that this small subtlety in work brings great results!

So, the corner is used in the following areas:

• for partitions and walls that need to be plastered and leveled;
• for corners (external, internal) that need to be made stronger;
• for arches, boxes, so that they are strong and even (not crumbled).

Since most partitions, arches, boxes, and trims are made of plasterboard, it becomes clear that it can crumble around the edges if it is not secured and plastered. You just need a corner for this.

There are two types of plaster corners:

• straight;
• arched.

Well, corners can already be used for many categories of interior finishing, but they all relate to plastering and puttying work.

What is a straight perforated corner

Straight perforated corner- This is a metal or plastic finishing element for corners, which is attached with plaster or putty, thereby giving the wall a smooth appearance and making its corners stronger.

It can be external and internal, as well as different in width and strength. For example, a wide galvanized corner is much stronger; it is also used as a beacon for plaster.

• It is better to take scissors for trimming corners with a plier-shaped type, they are very strong and sharp. With ordinary scissors, you will simply damage the edges of the corner, and the work will be lengthy and inconvenient.
• If it is a plastic corner, then large sewing scissors will do; sometimes you can cut it construction knife, but then the edges will have to be aligned using pliers or a hammer.
• The right angle looks like two long rulers folded in half, and on each edge there are round holes– this is a perforation that has its own top.

• The top of the inner corners is directed inward, and the outer corners are directed outward.

• The perforation is for fastening, and the apex is for direction; the craftsmen orient themselves towards the apex and guide the spatula along it.

• If you have a lot of work to do, where you need to cut a lot of corners, then do the following best: put them in a row, measure them, lift them to a height and cut them with a grinder. This will make working quickly and conveniently, and you won’t have to align the corners. Metal corners can be cut with pliers three at a time, this is faster.

How to use the corner and what it is intended for

The corner is used by installation method in two cases:

• If there is a crooked angle. Then the corner needs to be cut along the edges and adjusted so that the corner takes on an even appearance, then putty and dry, again, and if necessary, three times.
• Conventional fastening, at a straight (even) angle, uses a perforated corner.

External corner

Please note that covering too much flat angle ok plaster is not placed on the outer corner. Otherwise, it will then crumble under the finishing material, for example, wallpaper.

It is better to go through it once, so that the plaster is inside the perforation and slightly covers the corner. The corner of the corner itself should not be completely covered.

Strong fixation is necessary only where the outer corner itself is uneven or rotten. This type of putty is also used in bathrooms, only then the composition of the putty becomes more dense.

Internal corner

But it’s better to cover the inner corners a little harder, but also without fanaticism. They need to be dried and watched to check how the process has gone. Usually there should be no problems, but if you are installing corners to strengthen the corners, then use a wide corner and a thicker putty composition. Add a cement mixture to it and walk a thin layer 1-2 times around the corner, it will instantly become strong.

Plaster perforated beacon

Typically internal and external corners that are plasterboarded or on load-bearing walls are exposed frequent use, for example, in the kitchen - these are the main corners of the room. They must be made very high quality and tightly reinforced. That's why they are called plaster beacons.

Can be used:

• gypsum plaster;
• a mixture of gypsum plaster and cement;
• mixing cement mixture and gypsum plaster.

It is best to mix a cement mixture and gypsum plaster; it is not too dense, but not a weak solution. It dries very quickly and securely fixes the corner. Then it does not crumble and holds up perfectly.

Apply it with your hands very quickly and level the angle, and then go through it with a spatula, and so on until the end. You shouldn’t apply the entire mixture over the corner at once, it dries quickly, do 10-15 cm at a time. It’s most convenient to first fix the corner at the top and bottom, and then continue working.

Measure everything you need with construction tools so as not to ruin the corner. In places where the wall is too thin or dilapidated, you can use a mesh.

This plaster mesh reinforces the corner and makes the walls near the corner stronger. The corner itself is attached very securely.

• You can also stick a sickle mesh onto a regular corner; you can cut it a little wider than the corner and grab the wall with it. This is done in order to secure the corner as securely as possible. Then it is not necessary to use a mixture of gypsum plaster and cement; gypsum plaster will be sufficient.

How to use a corner to create a protective pad

Let's consider three options for using a corner as a protective element for wall corners.

First, this is when the walls in the room are already plastered, leveled and everything is ready for repair.

• If the walls are prepared for Finishing work, then you just need to secure the corners with regular putty, as described above. Without fixing the corner too much. We only need it to maintain an even appearance and begin gluing or painting the walls.

Second, for example, when the repair has already been made, but the corner is damaged and needs to be strengthened. Or, if there is no repair and it is not planned, but the corners need to be tightened, etc.

• Here it is worth taking precise measurements, initially plastering the wall near the corner and the corner itself, and then using gypsum plaster and cement to make a corner for the lighthouse.

Third option when you need to secure and align the corners of an arch, box, or partition.

• In this case, it is enough ordinary plaster, but sometimes, in cases where it is necessary, a mesh is used to strengthen the corners.

Such actions are necessary to align and strengthen the corners.

For thin items or hard-to-reach corners, you can use construction adhesive.

There are also self-adhesive corners on sale, but they are used only for such corners as, for example, an arch made of durable plasterboard, boxes in the wall, etc.

To join corners, it is necessary to select identical corners and suitable sizes.

Plastic corners are perfect for residential premises, where necessary. But, for example, for office, shop and other non-residential premises Where there is a lot of traffic and activity, it is better to use aluminum corners.

Slopes using a corner

Making slopes yourself is very difficult if you don’t professional master, but it is possible. Keep in mind that attention always falls on the slopes, and they must be strong, perfectly level, and smooth. The future condition of the window also depends on how the slopes are made. If the putty is applied incorrectly, the window may begin to fog up, cracks may appear, and there will be a draft from the window.

Initially, you need to thoroughly putty the entire window and prepare it for working with the corners. It is necessary to constantly measure the slopes and measure them with a construction ruler to ensure that they do not have unevenness. The same goes for door slopes. Then proceed to the corners, here the lighthouse technology is used. You need to securely fasten the corners, but very evenly. Because inner side there will be no finishing materials. In order for the angle to be very even, you need to slowly apply the mixture, stroke by stroke, 10 cm at a time and immediately level it with a spatula.

Advice. Prepare two spatulas, new ones, so that there are no stuck or dried mixtures, paint, etc. on them. With their help it will be easier to make a perfectly even angle. Having leveled, immediately apply two spatulas on both sides, pressing them tightly, and hold for about 20-30 seconds. Actions for every 10 cm should not take more than 1.5 minutes, otherwise the mixture will dry out and you will not have time to trim the lines between strokes!

Or buy a spatula like this.

Having completed everything, wait until the corner dries. Then check with a clean hand by lightly rubbing it and then using a ruler. If small unevenness or roughness is found, then do not panic, you will just have to work a little more. Take the grout (sandpaper) and, without being too zealous, slowly, in a circular motion, like a mechanical device, rub out the imperfections from top to bottom. And so on both sides, then measure again. Then you can walk a little with a roller dipped in plaster. As a result, the slope is painted inside with a special paint, preferably with a roller.

Application for arches

It is not so difficult to work with arches where right angles are present. Here you just need to reinforce the opening so that it is strong and has an attractive appearance. appearance. For such work, arched corners are used; they fit together easily, and it is not difficult to plaster them.

An arched corner doesn't look the same as a perforated corner, it's a little different.

Arched corners are made of plastic. There are leaf-shaped slits on the lines. Therefore, they are easy to select to match the required arch shape.

Standing in a store, you will be faced with the question of which corner to buy, soft or hard. If the arch is large, then it is better to take a solid corner. Suitable for a small arch, for example, in an apartment couch.

Before you start installing the corners, squeeze it so that later the leaves do not stick out through the putty. It is difficult to work with an arch alone; it is better to bring an assistant.

When you start working on the corner, you will notice that it bends back to make the puttying process easier; you can secure it with buttons. This will allow you to complete the job faster and smoother.

If the corners of the arch are very curved, then it is better to use a soft corner. In this case, you can use self-tapping screws that will securely fix the corner and in the future it will definitely not fall off. You just have to choose the right screws and fasten them more tightly so that they don’t show through the corner.

Fastening an arched plaster corner with self-tapping screws.

Cost of corners

Using plaster corners is inexpensive and convenient:

• perforated from 11 rub.
• reinforced perforated from 12 rub.

Please note that if you need repairs big house, apartments or office premises, then, of course, you will need a lot of plaster corners, but it is much cheaper than leveling the corners with a profile or other expensive materials. Moreover, if you do everything diligently, the quality will please you.

Plastering and finishing corners are different products. Each of these building materials your purpose, don’t get confused!

Perforated plaster corner

A perforated galvanized plaster corner helps in finishing many parts of the room. The master finisher achieved compliance of these places with the intended design thanks to experience and skill. After all, it is extremely important that the area is straight or oval, where necessary. Today, finishers come to the aid of devices that significantly simplify and speed up their work.

Today we will tell you where and how a perforated plaster corner is used. Also in the video in this article you can find out additional information about the use of this material.

• Where is the corner used?
  • Straight perforated corner
  • Corner like a plaster beacon
  • Slope finishing

Where is the corner used?

Master finishers try not to advertise that beauty smooth walls largely depends on the edging.

This definition implies such areas of use of putties and plaster mixtures as:

• Connection of walls with floor and ceiling;
• Internal, external corners;
• Arches, boxes, corners, channels and other similar structures

At their core, all accessories refer to perforated corners for plaster. There are only two main types of corners: arched and straight, which in turn are divided into different categories. The scope of their use is extremely wide, and covers almost all types of work related to plaster and putty.

Straight perforated corner

The perforated plaster corner is available in two versions: internal and external. The materials used for their manufacture vary from plastic to galvanized, and the width of the corner also varies.

When using one corner or another, it is worth starting from the task at hand, since there is no global difference between them. Although the galvanized corner is more rigid than others. This property allows it to be used as a beacon for plaster, especially if it is wide enough.

Application of straight perforated angle

Attention; To use a corner, you must choose metal scissors of the appropriate quality. Otherwise, poorly cut edges of the corners will interfere in the future.

• If you use plastic corners, you can even use a stationery knife to work with them. However, if you don’t have any tools at hand, you can break the perforated corner with your hands. In this case, the edges will then have to be straightened using a hammer or pliers, or even manually.
• The straight perforated corner for plastering works looks like the English letter “V”. Moreover, its flat sides are perforated, and the top protrudes about a millimeter. It is characteristic that those corners where it is directed inward are called internal, and external, respectively, those where the top looks outward. The top serves to guide the spatula, and the perforation is necessary to attach the corner itself

Attention: You can cut a dozen corners of the required footage using a tape measure and a grinder. To do this, you need to fold the corners one to one, and then, after measuring the required length, use a grinder. To work with a small number of products, you can also use scissors, however, if there is a power tool not far away, then it is better to use it.

The purpose of the corner and how to use it

Perforated plaster corner is used to strengthen the corner and give the correct geometric shape.

Installation of this product occurs in two methods:

• A curved corner, in this case, if the radius is not large, you will need to make cuts along the stiffeners so that the corner takes the desired shape;
• Right angle, in this case the corner is simply attached along the plane in the form in which you purchased it.

Corner like a plaster beacon

In the first option, the corner will be used as a plaster beacon. To install it, the plaster is placed on the main corner. It is worth noting that if you have sufficient finances, then it is better to choose gypsum plaster; working with it is much more comfortable.

• This plaster mixture is applied not along the edge, but in strokes in the form of a cake. This is done for convenient setting of the angle. The corner is set according to the plane and level, using construction tools, in particular rules and levels.

Attention: If gypsum plaster is mixed with cement or cement mixture then the beacon will rise within a few minutes, after which you can continue working.

• In order to avoid overlap of perpendicular planes, it is better to cut the working corners at 45 degrees. It is worth noting that it is undesirable to use an internal perforated corner as a plaster beacon. With its help it is better to emphasize the straight lines of the edging.
• In places where outer corner is exposed to frequent mechanical stress, it is worth using a corner that has plaster mesh. A plaster mesh made of fiberglass in combination with a corner made of plastic or metal, if necessary, reinforces the corner. These categories of perforated corners are used as plaster beacons. Because, hide the mesh under finishing putty You will need to apply a layer of plaster at least 5 mm thick.

Attention: If you use a regular perforated corner as a reinforced one, you can glue a mesh onto its shelves - a serpyanka that grips the wall. As such a mesh, you can use materials such as non-woven fabric and fiberglass. Putty can be used as an adhesive element.

Using a corner as a protective cover

In the case when the wall has already been applied high quality plaster, then perforated corners for plaster serve to protect the corner from severe mechanical damage and emphasize its straight lines.

• This corner is installed similarly to the first option. The difference is the use of a more liquid plaster mixture, and its layer should be as small as possible. For such tasks, as a rule, plaster corners made of plastic or aluminum are used.
• Moreover, it is not necessary to use plaster mixtures or putty for installation. The corner is adjacent to the surface, covering it because the base is already level. Installation of such a corner with a thin layer of plaster mixture as an adhesive element is used when working with gypsum plasterboard products.
• It is important that these structures are assembled properly. For such work, a perforated corner is used, on whose shelves self-adhesive strips are applied; such products can be used by moistening them with water.
• In some cases, there is a need to connect corners, in which case it is important that the joining corners are made of the same material. This is due to the fact that different corners can have different sizes, which will ultimately have a negative impact on the finish.

Attention: If the room is frequently walked, then it is better to use a galvanized perforated plaster corner. It is more rigid and better withstands the loads of plastic.

Slope finishing

Slopes on windows and doors should be treated with special responsibility because... upon visual observation there is an involuntary comparison with door or window openings. In other words, the straightness of the lines is assessed. If you do everything with your own hands, then attention should be at its best.

• Not even any minimum deviations there should be no lines from door or window lines. You should also check that window openings are level; they may collapse. Basically, when plastering slopes, craftsmen focus on the level.
• Therefore, it is recommended to use a perforated corner for this, which can also be used as a beacon. If gypsum fiber boards or gypsum boards were used when installing slopes, and the quality leaves much to be desired, the corner will help eliminate the shortcomings.
• It is important that when working with a brick slope, sandwich products, installing gypsum boards on a slope along building regulations and as a rule they need to be plastered. A perforated corner in this case will facilitate the correct alignment of the drywall.

Perforated corner for arched openings

Working with right angles in most cases does not pose any particular problems. Here's how to get it to optimal option arched, figured structures or multi-level ceilings?

After all, the familiar fold here Building tools, a straight perforated corner will not help either. For these works, a special type of perforated corner is used, which is called “arched”.

Photo of finishing the arch with a perforated corner

• Such a corner is always made of plastic, and one of its shelves is cut into petals. This design of the product allows you to change configurations to most accurately match the curves of the surface.

Attention: When using arched corners, be extremely careful; they cannot be corrected. In this case, the corner is set exclusively visually.

• To do this, the room must have good bright lighting and the help of a partner is desirable. Before installing the product, squeeze it, otherwise petals will protrude from the plaster.
• An arched perforated corner can be either hard or soft, it depends on the manufacturer. A rigid corner is necessary when working with three-dimensional structures, where there are many smooth shapes and bends. Although, the price for it is usually higher.
• The bent arched corner tries to straighten, providing the necessary roundness of the lines and leveling out the “angularities”. If you try to use a corner on small design details, where there are many steep transitions, it will break and it will be impossible to fix the work.
• For finishing steep transitions and arched openings(see How to decorate an arch: arch shapes and types of finishes) with a small radius, it is worth using arched corners from soft materials. The lack of rigidity in these products is fraught with the formation of depressions and tubercles in the future, which will spoil the smooth transitions. To avoid such difficulties, these arched corners are installed using plaster mixtures. Moreover, this installation method allows you to correct visual defects during plastering.
• It is important that self-tapping screws and similar installation elements will not damage the lines being processed. In order for the corners to look more attractive, they should be installed with a little effort, stretched.

Corners from an economic point of view

Perforated corners for plaster, and other similar products have a relatively low cost, ranging from 40 to 50 rubles. This applies to corners made of plastic and aluminum.

The same galvanized product would cost a little more, about 60 rubles. A rigid arched or reinforced corner will cost much more, approximately 150 - 200 rubles.

• Naturally, when decorating an entire cottage or private house, the number of such corners will be in the dozens. After all, it won’t always be possible to connect even in construction garbage a lot of items may be wasted. In this case, the estimate will be impressive. However, the reliability of protected corners with the help of these accessories also costs money. Don’t forget about the speed of finishing using corners and the positive visual effect.

Attention: Do not confuse finishing corners with plaster corners, these are completely different products that are decisive different tasks. The finishing corner is used at the final stage of finishing. To install a plastic corner, it is optimal to use liquid nails. Keep in mind that finishing corners are also divided into types and subtypes.

• When drawing up an estimate for home decoration or renovation, it is definitely worth taking into account the costs of corners. Otherwise, the effect of finishing work will be incomplete. When choosing such products, you should rely on the opinion of the master; he will have to work with them.
• It will be the same with its use. significant savings and by time. Indeed, in this case, finishing the angle will not take much time.

A perforated plaster corner will help you get the job done quickly and efficiently. Therefore, you should not be afraid of the costs of purchasing it, it will pay for itself and that’s for sure. And the instructions will help you do it right choice.

Galvanized corner for plasterboard 25x25 mm is one of the types of material that is used to level parts of walls. As you know, drywall is popular in construction and is easy to work with. However, prefabricated ones have problem areas– corners that are most often subject to mechanical stress. This is where they will come to the rescue different kinds existing corners.

Existing types corners for drywall

They perform protective function parts of the walls and will help build even corners. Knowing their classification, you can choose a suitable specimen.

The most common product options are:

Metal perforated corner

This type is a thin sample made of a profile with perforation and a rigid edge along the edge. There are basically 2 types of similar corners for drywall:

• straight;
• arched.

These representatives have many subspecies. The corners are not glued, they are practically “slung” onto the structure and secured with putty or.

Straight perforated angle is used to process the inside and outside of corners.

It is a V-shaped profile with many holes - perforations.

Options for metal perforated corner for drywall

Actually, with their help, a high-quality connection occurs with the processed corners, and the apex located at internal corners– inside, and for external ones – outside, serves as a guide for the spatula. Excess air also escapes through the holes. Straight perforated corners are made of plastic, aluminum, and galvanized. The latter is tougher than the others, and the wide one can generally be used as a plaster beacon.

Plastic corner

This sample is more resistant to moisture than the profile, but its resistance to mechanical damage is lower. Among the advantages can be noted low price and no corrosion of the material. There is also a type of plastic corner, for example, AquaBead, which has special paper with glue applied in the inside.

Putty is not required for fixing here; just moisten the adhesive surface with water and simply glue the corner to the desired place.

Arched

• Various finishing materials are used, such as plaster, wallpaper, panels and others. But in order to preserve the transition points between planes, an arched corner, which has great capabilities, is used. Arched corners are divided into the following types:
• Installed under plaster, perforated. They have separate petals on one side of the corner, allowing you to place a sufficient strip on any arched curve. There are plastic and profile ones;

Decorative, which are glued to the plaster.

This is what an arched corner for drywall looks like

Before attaching the arched corner, you need to match it with the main finish or in contrast, so the design will look more original.

Such elements are used in places that require strengthening corners and protecting them from damage. Plaster mesh corners are intended for internal and external corners. They can be made of either plastic or metal profile. The choice will be influenced by the shape and material of the finishing surface.

Installation of corners on drywall using corners

When starting to install a corner on drywall, you need to have tools and material on hand.

Required material

• the selected type of corner will need to be purchased with some reserve;
• by using ;
• It is best to buy Vetonit putty, which is of high quality.

Tools

• metal scissors will help you cut out the necessary parts correctly and quickly;
• a brush that will be needed to apply the primer;
• wide and narrow spatulas will be needed for;
• The sanding block will remove all unevenness on the plane, while the angle will be perfectly even.

This is what mounted corners look like on drywall

When starting installation, you need to familiarize yourself with the sequence of leveling the corners with putty so as not to damage this fragile material.

Stages of work

1. First, the surface must be thoroughly cleaned and treated with a primer. You need to proceed to the next stage only after it has completely dried.
2. Measurements are taken and the required length of the corners is cut. They are applied to the drywall as a sample.
3. For further work you will need non-woven tape, serpyanka mesh - for internal corners, one of the types of perforated corners: plastic, adhesive, rounded or metal profile or on paper.
4. Before you make a choice, you must make a choice. To form internal and external corners, it is better to buy a dry gypsum mixture. It has a reasonable price good quality and will be able to securely fasten the elements to the structure.
   
5. The putty is prepared following all the steps: poured, poured, stirred, allowed to settle, kneaded again.
6. When working with external corners, you need to remember that they are most often subject to mechanical stress; it is better to mount metal samples, in some cases having a rounded shape.
7. Check the flatness of the end.
8. Putty is applied to the area to be treated with smooth movements. Without allowing the composition to dry, you need to secure the corner with pressure, check the accuracy with a level, and if necessary, you can tap with a rubber mallet.
9. Sometimes the corner is attached to the drywall with a stapler or glued with glue, and then covered with putty.
10. Another layer of the mixture is applied to the installed element and now leveling occurs common plane walls.

    Applying a second layer of putty

11. After thorough drying, the slope corner is polished.
12. Installing corners inside the structure looks similar, even a little simpler. Carefully coat the adjacent sides and the gap between the corners with a spatula, and remove excess mixture. On a dry, sanded surface that has the desired shape. You can buy it, just apply it to wet putty.
13. check the fastening of the corner on the plasterboard, then use the next layer to hide the unevenness.
14. After thorough drying, the surface is finished with sandpaper or a sanded block, forming a perfect angle.
    
15. To facilitate the leveling process, so-called beacons are used, attached to the surface with a plaster solution; here you can do without fastening parts.
16. Separately, I would like to mention the semicircular plastic corner, used in rooms with the maximum possible impact on the corners. It is made of flexible plastic and has a semicircular angle rather than an acute one. Its price is quite reasonable, and its durability is beyond doubt. It differs in some features at the installation stage, namely cutting the end by 1.5-2 cm with an angle of 45 ͦ . A corner is pressed into the applied initial putty, fixed with a stapler, and the edges are treated with the mixture.

A video of arranging corners will help you see how parts of the drywall are reinforced, and will also allow you to select and buy the necessary elements.

Finishing internal and external corners will not seem difficult when the right approach and the necessary training. The main thing is that during installation there should be items that require minimal finishing.

Great competition in the production of building materials contributes to the emergence of high-quality products at a reasonable cost. In addition, many manufacturers enter the market with new products and devices that previously finishing specialists had no experience working with.

Such products include a plaster corner - an indispensable part for production interior decoration premises. By using this item correctly, you can be sure that the corners in the room will become smooth and reliable.

Plaster corner and its varieties

Metal corner

Each owner, when undertaking renovations in his premises, very often faces the problem of leveling the walls and creating a high-quality cover for the organization finishing. Paying attention to the corners in the room where the renovation will be done, many people do not know them.

Modern developers involved in the production of various construction products have created and implemented in “ construction world» such an invention as a corner for plaster , to which not only finishing professionals are grateful, but also ordinary people who carry out their own renovations in their apartment.

Plastic corner

This item is used to form an even internal or external corner. Despite his simple design, it requires certain skills to install it.

Today there are 2 types of design:

• metal profiled corner;
• plastic corner.

Each of the above options has its own scope and certain advantages and disadvantages.

Metal corners for plaster

Aluminum fittings are lightweight and more reliable than the galvanized version

Plaster corners made of metal are classified according to the shape of the structure and material.

The materials used for the production of this type of plaster corners are galvanized steel and aluminum.

Despite the fact that aluminum can be classified as a rather soft metal that requires careful handling, corners made from it are widely used, since the material is slightly susceptible to corrosion, and products made from it can last for many years. In addition, the aluminum corner is lightweight, which subsequently does not place additional load on the surface.

A corner made of galvanized steel is more susceptible to atmospheric influences than its aluminum counterpart, but at the same time has greater reliability.

In order for a galvanized steel corner to serve you as long as possible and not begin to corrode, it must be cut only with metal scissors, not electric ones. grinding tool. Installation of products should be done carefully so as not to damage the zinc layer.

According to the shape of the structure, all metal corners are divided into 3 types:

1. Regular angle. It looks like a metal strip, bent at 90 0, up to 0.5 mm thick. Usually, on the sides of the product, depending on the manufacturer, there are perforations, which lighten the weight of the product and give it additional adhesive properties.

2. Arched plastic corners. The structures help to create a high-quality arched opening in the room. Due to the segmentally divided 1 edge of the corner, its surface can be bent to different radii, thereby creating an even angle even in a difficult situation.
3. Corners with overlay mesh. Such products are used in places where it will be applied thick layer plaster. Mesh extensions create an additional fixing base. This results in a high-quality angle even in the most difficult conditions.
4. Universal angle. It has a mesh design and can be used to create non-standard angles (excellent) due to the high-quality plastic used and a specially created fold line.
