Installation of perforated corners. Perforated corner for putty - which one to choose and how to attach How to attach a perforated corner to an external corner
Below we will tell you how to properly install a metal corner on vertical angle walls, which will be useful for those who are used to working at home themselves, without calling a finishing specialist for every little thing (I would go again).
The need to install a metal perforated corner is not due to the whim of the owners, but to the fact that this element allows:
- — Faster and more accurate alignment wall corner,
- — Additionally strengthen the corner, protecting it from accidental mechanical damage.
What is needed for installation
To perform the installation, you do not need to prepare much material and tools. You will need:
- — Gypsum-polymer mixture Rotband,
- — Level (from 1 meter),
- - Several metal spatulas,
- — Plastic container for kneading.
Corner installation
Many are accustomed to thinking that the main thing in the process of installing a corner is the accuracy of its vertical installation, however, it is necessary to control the accuracy of the work along the plane of the adjacent walls (photo 3), because otherwise holes or bumps will appear on the wall.
The Rotband mixture is mixed to a medium consistency (first water is poured into the container, then the mixture is poured) and applied to the base of the outer corner with a spatula (8-12 cm) after 10-15 cm. The corner is applied to the corner without pressing, then a level and corner are taken in hand straightened vertically and laterally.
It is important not to try to completely align it along one vector at once, since there will be no margin left for editing along other planes. Slightly align the corner vertically, then press it with a level along the line of the wall, then accurately align the vertical. Deviations should not exceed 2 mm per linear meter, but this is the maximum, full list permissible deviations (quality indicators).
Leave the leveled corner to fix (20-40 minutes), then use the remainder of the mixture (Rotband does not set for an hour) to zero its side edges. When removing the sidewalls, use a wide metal spatula, which should go from bottom to top, this way you will avoid the appearance of holes in the saddle of the outer corner, and vertical accuracy will be ensured by the corner itself (its outer edge will act as a guiding beacon).
After a day, the corner can be puttied in one or two layers, depending on the type of further finishing (1 layer for wallpaper, 2 layers for painting).
Questions and answers
Is it possible to attach a paint corner during plastering work?
Theoretically it is possible, but there are several “buts”. Firstly, it's more labor-intensive process, especially when working with classic lime-sand plaster. Secondly, the paint corner will not adhere well to the plaster mixture, since its perforation is made for putty (there is a mesh underneath the plaster).
Is it necessary to buy corners with reinforcing mesh on the sides?
No, it’s not necessary, but due to the mesh, the corner stays more securely on the corner and is difficult to knock down even with accidental physical impact.
The most important indicator of quality when installing beacons is the accuracy of their vertical installation?
No, the metal corner must be precisely fixed not only vertically. Pay attention to the second photo - the angle must be even on the wall, often you have to either knock it down top part corner, or run the corner above the wall level and then smooth out the unevenness with plaster.
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 perforated plaster corner. 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 OK
- 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 her is much more comfortable.
- Apply like this plaster mixture not along the edge, but with 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 the shelves of which 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 corner is used for processing 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 the resistance to mechanical damage is lower. Among the advantages we can note 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.

Before attaching the arched corner, you need to match it with the main finish or in contrast, so the design will look more original.
Products with mesh 
Such elements are used in places that require strengthening corners and protecting them from damage. Plaster mesh corners are designed 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
- 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.
- Measurements are taken and the required length of the corners is cut. They are applied to the drywall as a sample. For 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.
- 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.
- The putty is prepared following all the steps: poured, poured, stirred, allowed to settle, kneaded again.
- 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.
- Check the flatness of the end.
- 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.
- Sometimes the corner is attached to the drywall with a stapler or glued with glue, and then covered with putty.
- Another layer of the mixture is applied to the installed element and now leveling occurs common plane walls.
Applying a second layer of putty - After thorough drying, the slope corner is polished.
- Installing corners inside the structure looks similar, even a little easier. 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.
- check the fastening of the corner on the drywall, then use the next layer to hide the unevenness.
- After thorough drying, the surface is finished with sandpaper or a sanded block, forming a perfect angle.
- 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.
- 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 no sharp corner, but semicircular. 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 production building materials contributes to the emergence of quality goods 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 make their own repairs 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:
- Regular angle. It looks like a metal strip, bent at 90 0, up to 0.5 mm thick. Usually, depending on the manufacturer, there are perforations on the sides of the product, which lighten the weight of the product and give it additional adhesive properties.
- Plaster corner with mesh. Metal corners of this sample are widely used in plastering work. wet method. The design feature of this product is that it is attached to the corner using special pads. metal grid 2-4 cm wide. Using this design, you can level a wide variety of surfaces.
- Combined angle. This is the type metal structure, consisting of aluminum or galvanized corner and fiberglass mesh. With its help, clear angle shapes are created on the surface, and the joint is formed correctly using a mesh. To find out which option is better to choose, watch this video:
A metal corner for plaster can be called ideal option for finishing work, but due to its significant shortcoming(susceptibility to corrosion), experts recommend using it only under gypsum putty or latex coating.
Plastic plaster corners
Plastic structures create quite a lot of competition with their metal counterparts in the building materials market. There are several types of plastic linings installed in the corners:
- Standard plastic corner. Similar to metal structures. Its main difference is that it does not corrode. Its main drawback is the thickness of the product, which can exceed 1-1.5 mm, and makes its use impossible when putting surfaces, but it is excellent for plastering work.
- 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 flat angle even in a difficult situation.
- 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.
- 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.
The main advantage of plastic plaster corners is their anti-corrosion properties, allowing them to be laid in cement-sand mortar, which continues to be a popular plastering material.
Fastening the plaster corner
Arched corner It is not enough to choose a high-quality product for framing corners made of metal or plastic; the main task is its installation. There are certain nuances and postulates that every professional finisher recommends following. These include:
- there should be a strong wall at an angle;
- the corner must be primed, just like the walls;
- the corner is set according to special, built-in level;
- the corner should be installed in such a way that the solution penetrates into all perforations;
- the verticality of the installed product should be controlled using a level;
- in extreme cases, when the layer finishing material too thin, it is allowed to use additional mechanical fastening, which can be dowels with plastic sleeves and self-tapping screws;
- plastering work on the corner element is carried out last;
- there are special tools for shaping a corner and removing excess mortar from the surface of a plastic or metal product;
- Grouting the corner should be done on both sides alternately, while the product itself should not protrude outward.
If, when comparing the corner trim with the wall surface, you see that the mortar or gypsum composition is not enough to recess the corner, you should use some kind of leveling compound or sealant for these purposes.
To summarize the material presented, it is worth saying that the plaster corner is an indispensable assistant for the owner of an apartment or house who is trying to do it himself for the first time Finishing work in your premises.
By making the right choice of product and performing high-quality installation in accordance with the recommendations, you can be sure that the corners in the room will be even.
Expert builder Viktor Petrovich says:
Here we come to the kitchen. Now we will install perforated plastic and PVC corners. To begin with, we clean everything here so that there are no build-ups, remove dust, prime, install corners and plaster the slope.
Now you will need to quietly remove everything and clean it. So we cleaned the slopes. Now we will prime the slopes with a primer: we use Aquastop primer concentrate, dilute it with water and apply a coating. It is inconvenient to prime here with a roller, since the slope is small, so we take a brush or brush.
For those who have not watched the previous videos, I will explain that this niche is for a TV, that is, we will mount a TV here. Here we will have two sockets: two of them will be low-current and two power, that is, analog twisted pair and 220 sockets.
Here we will now install perforated corners using a laser level. You can see we have a laser beam here: we have already set up the laser, and, accordingly, our slopes will need to be plastered. Now we take and stir the plaster solution using Volma Layer. This is how the solution is applied to the perforated corner.
Yes, our primer has already dried, on the slopes we mean. And now along the line of the laser level, laser beam The corners are set. Here, you see that on the stiffening rib on the outer corner of the corner you can see the red beam of the laser level - this indicates that our corner is aligned with the laser beam.
Excess is removed with a spatula. Once again you will need to check, look, push somewhere, press. Well, here, in fact, the corner is exposed. The edge of the corner is coated in the same way, and we will also have putty on top. Before applying the plaster layer when installing corners, be sure to prime.
Now we will install a perforated plastic corner on the upper slope of the niche, where we have a wooden lintel. We will freeze it now and then, when the plaster mixture rises and dries, we will screw this from below with self-tapping screws. plastic corner so that it doesn’t fall off from us.
Why do we install plastic perforated corners in a niche? Firstly, aesthetics. Secondly, it will be smooth and beautiful. Thirdly, it will protect the corner, that is, so that when the TV is mounted, the corner will not be demolished, not cut off, so that there will be no chips on the corners. This is what it is installed for.
So, let's install laser level in such a way that the beam would be as close as possible, as close as possible to the slope. Here we installed perforated corners level on both sides and on top of the slopes. You may ask why we didn’t install the fourth corner from the bottom? I'll tell you in the next video why we didn't install it.
