In this article, we'll take a look at the installation process. perforated corner. In particular, we will deal with the questions: how to fix the corner, how to align it, how to make finishing. For maximum clarity, the article is supplemented with relevant photographs and videos.
First of all, a few words about what is required to complete the work. So, in addition to the perforated corner, we need the following materials and tools:
- spatula (50 mm);
- spatula (150 mm);
- nozzle mixer (for a drill);
- maklovitsa (wide brush);
- building level;
- deep penetration primer;
- dry gypsum putty ("start").
Regarding the perforated corner. In this case, it all depends on the corner, the finishing of which you will be engaged in. If work is underway to repair the outer corner, in the room where there is most likely its damage, it is best to use plastic corner. Such a room, for example, is a corridor.
Of course, the use of a plastic corner is not mandatory requirement rather than a recommendation. For finishing, you can equally successfully use both metal and plastic corners. Simply, plastic, in comparison with metal, is more advantageous in terms of durability: they do not crumple in the event of fairly strong blows.
Preparatory work
We figured out the tools and the type of corners, you can proceed to the preparatory process. It comes down to priming the repaired plane and preparing a gypsum mortar.
First of all, we prepare a solution from the starting gypsum putty. By the way, for gluing a paint corner, you can use not only the starting one, but also finishing putty. You can also use various cementitious adhesives, such as adhesive for laying ceramic tiles.
The solution is prepared as follows: we collect a certain amount of water in a clean container, add the dry mixture to it and stir everything with a mixer. Important: the solution for installing a perforated corner should be quite thick - much thicker than, for example, for puttying walls or for gluing a ceiling foam tiles(pasting the ceiling with tiles).
So, the mixture is ready, you can proceed to the primer. Here everything is simple and fast: with the help of a maklovitsa, we apply the primer on the surface to be treated, smearing it evenly. There is no point in priming several times - once is enough.
Installation of the perforated corner and its alignment
With a small spatula, we apply a small amount of putty mortar to a larger spatula and with its help we transfer our glue directly to the corner being repaired. We perform this work along the entire height of the corner.
Now we lean the perforated corner and gently “press” it. By pressing / pulling certain sections of the corner “by eye”, we align its verticality.
Next, we take the building level and with its help we check the evenness of the installation of the paint corner. If necessary, carefully, so as not to damage the corner, change its position. Thus, we achieve a perfectly even angle.
At the end, we putty a corner on one side and the other. Most convenient to do this work after the putty, through which our corner is held, has completely dried. You can do this directly during the installation process, the main thing is to do everything as carefully as possible so as not to disturb the correct verticality of the corner.
When plastering and filling walls, the most difficult place is the outer corners. These are more often slopes of windows and doors, junctions of rooms with corridors, edges multi-level ceiling etc.
Corner framing - difficult task, even for an experienced plasterer. The best way issue outer corner in the conduct plastering works can be done with a perforated corner.
A metal or plastic corner embedded in the plaster gives the outer corner the desired shape and strengthens it. weakness, i.e. protects the plaster along the edge of the corner (in a thin layer) from destruction in case of accidental impact. The video shows the process of decorating the corner during plastering.
If the outer corner is 90 degrees, then a standard perforated metal corner - 90 degrees - is suitable for its design and plastering. The technology for installing a perforated corner is quite simple.
- A putty mortar is being prepared (often based on gypsum) in accordance with the instructions for use.
- A corner is cut to the desired length.
- The installation site of the corner is not covered with a thick layer of mortar. Putty is applied with a narrow spatula along the outer corner on both sides to a small width - 5 - 10 cm. The solution acts as an adhesive, therefore it is applied in a thin layer so that the excess does not have to be squeezed out from under the corner and then removed as waste.
- The corner is installed in its place, pressed into the solution. In order not to deform a corner of thin metal, it must be handled carefully. The corner is pressed into the solution using a flat rail of suitable length. It is more convenient to use a level or a rule.
- Then, with a spatula, excess mortar is removed, protruding through the perforated holes of the corner.
- In order to smooth out the irregularities associated with the installation of the corner, a layer of plaster (putty) with a width of about 40 cm is applied to the surface. The work is performed with a spatula of the appropriate width in two steps. First putty is applied to a width of 20 cm on both sides of the corner. Then the process is repeated, but this time with a putty strip width of 40 cm.
After that, the walls will become visually even, and the corner will be hidden in the putty.
Another case is when the angle of the walls is not 90 degrees. Builders call such an angle deployed. To design a developed corner, a flexible perforated plastic tape, which bends into a corner to the desired degree. Otherwise, the puttying of the corners of walls and ceilings is carried out according to the above technology.
First, the solution is applied, then the corner is glued - leveled with the rule, after which it is puttied with a wide strip of the solution.
After the putty has dried, the surface is processed for further decoration, for example, it is sanded, primed and painted.
In the video you can see how the corners of the walls and ceilings are plastered and puttied. The work is done by a master plasterer.

Attaching the perforated corner to outer corner helps not only to align the joints of the walls, but also creates protection on them from accidental damage. The perforated corner is a metal element up to 3 meters in length with side strips that are perforated to improve fixation.
To fix the paint corner, it is imperative to use a linear level, the length of which depends on the height of the corner. The material for fixing can be putty "start" or gypsum mixture with mineral additives that do not allow the composition to set quickly, but retain its plasticity.
As a rule, a solution is applied to the joint of the walls with a spatula, the corner is applied to the corner and aligned with the clamp with a long linear level. The accuracy of the work is controlled along the edge of the corner, as well as along its side lines. The remains of the solution are removed with a spatula and the perforation holes are closed with them.
There are corners that have on the sides, in addition to perforation, strips of reinforcing tape, which makes the coupling of the element with the sidewalls of the corner more reliable. The technology of fastening such a corner is no different from mounting a conventional metal element.
Increased attention is paid to fixing the corner when fixing it to the slopes. If your city of residence is Odessa plastic windows it has a place in the offices of many companies, however, a prudent owner should appreciate the means, therefore, when installing the slope, it is necessary to protect the window frame with masking tape.
The corner is installed on the starting putty or plaster plaster composition and is aligned with the vertical slope and the line of the wall adjacent to the window. For this, only a level of a shorter length is used. If alignment is not done along the wall, then a depression is formed, which can make its black contribution to the interior design. It is much easier to fix the corner on the slopes of drywall, because the GKL is pre-aligned during fixation (on glue or on the frame).
Learn how to putty drywall corners the right way!
In this case, a minimum amount of putty is required (necessarily “start”) and there are no additional difficulties.
A more difficult task is when fixing a protective and decorative element on a plaster slope. In this case, you can use a special plaster corner, which has a mesh instead of perforation. Its fastening should be carried out directly during the plastering work, but if the plaster is completed and the corner is not exposed, then its painting variation is used.
crooked installed corner dismantled and reinstalled again with a preliminary trimming of the corner of the walls.
Every person strives to inner space in window opening smooth, even and attractive. For these purposes, it is best to use decorative corners for slopes made of high-quality plastic, aluminum or other materials.
What is this design?
The inner surface of any window opening is most often made using plastic. Now it is the most affordable, inexpensive and best option for finishing. Plastic is much cheaper than drywall and is presented in different colors.
But the end of the plastic strip, which has partitions, with outside doesn't look very presentable. To finished work had an attractive appearance decorative finishes plastic corners are used. These are common profiles that are included with the cladding panel. 
Among the large and varied selection, one can find a section with L and F shape. At the enterprises they are made according to a special technology. The material is preheated to certain temperature, after which the hot bending of the rigid PVC sheet can be bent and given the desired shape.
Characteristics of profiles for slopes
Decorative corners for slopes will help hide small bumps or other wall defects. AT construction stores profile shelves are presented, which have various sizes. In most cases, the angle between them is at least 90 degrees.
Main types:
Less popular are designs that are equipped with asymmetrical shelves. Some people prefer to mount arched openings on windows, so you need to buy a special profile.
It is incredibly flexible and has standard sizes shelf widths. They converge at an angle of 90 degrees, and the total length does not exceed three meters.
If preference is given to an L-shaped profile, then it must be installed last. If we are talking about an F-shaped corner, then it needs to be glued only to the end of the PVC panel.
How to putty drywall: why do it and the sequence of work.
Thus, you can hide an uneven cut or other minor defects. To facilitate the work, the profile was specially supplemented with a special jumper.
Scope of aluminum corners for slopes
On the inside and external structure in most cases, it is necessary to additionally install an overlay that has increased rigidity. In this case, the craftsmen offer their customers to buy materials made of aluminum.
The presented design has the form of a narrow long corner, with a shelf width of 2.5 centimeters. There are several varieties of such a profile - it is decorative and perforated. 
How to choose the right decorative corner for slopes?
To decorate a room or any other room, you need to carefully finish the decoration. window openings. In this case internal design will look harmonious and complete.
To do this, you need to carefully and carefully select decorative corners for slopes, which are designed to decorate the inner surface of the opening.
The best option for such purposes is plastic, aluminum, brass and polymer structures. Experts have developed several good advice to help you choose the right decorative elements for the window and make no mistake with the choice. 
Profiles that have a shiny, perfectly smooth and matte surface look the most attractive and aesthetically pleasing. They are sure to fit any room or space. But it is worth noting that they will not be in harmony with classic style. This includes rococo, empire, baroque and well-known country design.
Aluminum structures look most attractive in a room where the owners prefer to stick to a minimalist style. Most best options- this is modern, hi-tech or gothic interior.
Expensive brass can easily fit into general interior absolutely any room or room. Many people consider this option the most optimal for registration. In an alloy of copper and zinc, manufacturers can add components such as lead, aluminum, nickel, and many other additives. 
The final type of coating may vary depending on the composition of the brass. Among the large and varied selection are blackened, silver or gold-plated options.
How to properly install the corners on the window slopes?
After completing the sheathing of the internal surfaces of the opening, it is worth starting to ennoble general design. For these purposes, decorative corners for slopes are ideal. At the time of purchase, each person should carefully check them for defects. The profile must be perfectly flat and have symmetrical sides. 
- Before installing plastic, aluminum or brass, it is necessary to carefully align the narrow strips of the wall around the entire perimeter. To do this, remove all existing screws from the curtain rod and clean possible sagging from silicone or plaster;
- Next, a corner is taken and the desired segment is measured. It is glued to the top of the opening. But all ends must necessarily protrude from each side;
- All joints are trimmed at an angle of 45 degrees;
- At the very least, the lower part of the structure is cut off before installing the window sill;
- The internal floor profiles are sawn off at 90 degrees.
Watch the video:
All work must be carried out in the correct geometry and accurately carry out all the drawings. For these purposes, experts recommend using a carpentry miter box.
A perforated profile (perforated corner) is installed to protect and align external corners.
Most often, such protection is installed on the outer corners of slopes, columns, openings, niches, arches ...
Some craftsmen, without bothering, fix the perforated corner dry with a mounting stapler, and then apply putty on top, but I think that this is not entirely correct. The perforated profile, regardless of the material - metal or plastic, primarily serves to protect and reinforce the corner, which means that the inner cavity under it should not be empty, but completely filled with strong putty, for example, CE 78, FUGENFULLER, UNIFLOTT ...
I will tell you step by step how I install the perforated profile at the corners of the arched opening. Installation arched profile on both sides, the thickness of the arch is more complex and has its own nuances in contrast to fastening the profile, for example, to the slope of the window. It is this option with an opening that we will consider.
First, we determine from which side of the opening you need to start installing protection. To do this, with a locksmith's corner, we check whether the end of the opening is unfolded. This is usually drywall partition and the drywaller does not always pay attention to this nuance. We start the installation from the corner that protrudes more (acute corner). If both corners are 90 degrees, it doesn't matter which side to start framing.
So with a spatula we put putty on the outer corner of the opening:
We apply putty on both adjacent sides of the corner without gaps, so that there are no voids under the installed perforated corner.
Before mounting the profile on the floor, it is advisable to put a lining or a wedge of a few millimeters, in this case a nylon dowel was at hand (seen in the photo). Such a "trifle" will not allow the profile to cling to the lower end and will allow it to be set without problems.
Carefully install the perforated corner, pressing it into the putty:
With a spatula, we remove the excess putty that has come out. After that, usually, a level is applied to the profile and with light blows rubber mallet placed in a vertical position.
In our case, the first profile has already been set. Now the second profile is to be set in such a way that the framed end of the opening is not turned, but has 90 degrees.
The difficulty lies in the fact that the installed perforated profile protrudes 3 millimeters beyond the plane of the wall. If we attach the locksmith's corner close to the plane of the wall, then we will not get an angle of 90 degrees. To compensate for the thickness of the perforated profile, you can use, for example, cutting the wire of the desired thickness:
Pressing the profile with a locksmith's corner with such a "fit" every 20-30 cm, we set it in the design position. To control the plane, the installed profile can be additionally checked with a level.
On the curved part of the arch, we expose the profile with the same locksmith's corner with a "fit" to maintain a right angle. To fix the arched corner in the design position, you can use self-tapping screws, screwing them into the holes of individual segments.
When working with drywall, it is necessary to learn the technique of processing corners when a perforated corner is fixed for putty. Aligning walls with a material such as drywall is a fairly popular procedure, as it easily solves the problem of the need to correct the curvature of the surface to be treated. That is why it is so important to master all the stages of work that will allow you not to resort to the help of specialists.
Puttying drywall corners - briefly about the main thing
Before you start working with drywall, you need to acquire and assimilate a number of relevant knowledge on how to level corners with putty. If the work is done incorrectly or inaccurately, appearance designs will not be the most attractive. And this, of course, is to be avoided. During the procedure, drywall can be damaged - the material is fragile and requires special care.
For processing external corners, special perforated corners made of metal or plastic are used. They help protect drywall from mechanical damage. To do this, putty is applied on both sides of the joint of the sheets on the outer corner. From above, a specially prepared corner is gently applied and pressed into the solution required size, which is subsequently completely puttied. To do this, another layer of the solution is applied. After the putty dries, the quality of the work performed is evaluated for evenness and, if it is not achieved, the treated area is primed and the solution is applied again.
The inner corner must be puttied with a sickle. The technique for performing work is similar to that used in the processing of simple seams. A right angle can be obtained using a special spatula. It is dipped into the solution and the joint is processed.
How do you putty corners with your own hands? What does that require? Is it necessary to have special knowledge, skills and experience, or is it available to everyone? Let's try to find answers to these questions.
Materials and tools for filling drywall corners
Before you start puttying the corners, you need to purchase all necessary materials and tools. Do not forget that the success of future work depends on their quality as a whole.
To process drywall corners, you will need: primary and finishing putty, perforated corners (metal or plastic), non-woven tape, sickle or construction mesh, metal flat and angled spatula, construction knife.
Arched perforated corners can also be useful for leveling drywall corners. They are used when processing surfaces that have a rounded or wavy shape, as well as for complex elements suspended ceiling.
On the this moment best of trademarks in the Russian market for the production of putty mixtures, Fgenfüller is considered. It is recommended to use it when processing drywall corners by most construction professionals.
Several possible workflows
For a more detailed consideration of this topic, we have divided it into several workflows and we will try to describe each in detail.
Scheme 1 Plastic corner AquaBead.
AquaBead is a plastic perforated corner coated with special paper, inner side which is covered with glue. It does not require the first layer to be attached to the corner to be machined. Glue is soaked with ordinary water. The work is carried out as follows:
- The drywall end is checked for evenness. The surface must be treated with a damp sponge or primer.
- A corner of the required size and length is cut off.
- The inner surface of the corner is evenly treated with water using a spray bottle. The glue is activated within 20-30 seconds, after which you can proceed with the installation. You can check the readiness of the adhesive for separation by touching the surface of the corner with your fingers.
- Corner is glued. To do this, it is tightly pressed against the corner and smoothed along the entire length.
- The initial putty mixture is being prepared. 20 minutes after gluing the corner, you can start puttying.
- A thin (about 2 cm) layer of putty is applied over the corner with a spatula. The surface is leveled to the maximum.
If you did not manage to use the AquaBead corner during the time and the glue froze, then you can re-treat the surface with water - all adhesive properties will be preserved.
Scheme 2 Metal corner.
Using metal corner for processing drywall corners:
- The initial putty mixture is being prepared.
- The end face is checked for evenness.
- A corner of the required length and size is being prepared.
- Putty is applied to both sides of the processed corner.
- A corner is leaned against the corner and pressed into the putty mixture. Putty will come out of the holes on the surface of the corner, which must be immediately leveled with the addition of a small amount of fresh mortar. Level the surface.
It is better to remove the excess mixture from the very corner of the corner, since it will not contact very well in this place and, accordingly, will be attached to the surface.
Scheme 3 Metal corner and stapler.
With this method, at the first stage of attaching a metal corner to drywall, not a putty mixture is used, but a construction stapler. Further, the top corner is also covered with initial putty.
Scheme 4 Semicircular plastic corner
This type of corners is used in rooms where the most likely mechanical influences on corners and walls. The corner itself has a rounded surface instead of acute angle and is made of highly flexible durable plastic. Features of its installation appear on preparatory stage. The processed end of the drywall must be cut one and a half to two centimeters at an angle of 45 degrees. Next, a plentiful layer of initial putty prepared in advance for use is applied. cropped under right size the corner is pressed into the mixture applied to the wall and additionally fixed with construction stapler. The edges are leveled with putty. The putty mixture must be removed from the semicircular part of the corner with a damp sponge.
Puttying the inner corner of drywall
- Place a sickle on the corners of drywall or construction grid. The joint should be exactly the middle of the strip of material.
- Apply pre-prepared putty mixture.
- Level with a special angled trowel.
Stage of final works
How to align the corners with putty at the final stage?
- After the last layer of the initial putty has hardened, be sure to check the corner for evenness. If necessary, prime it and apply another layer of the mixture to level the surface.
- It is very important to process the corners at the end finishing putty. It will help to further level the surface, making the corners more aesthetic. After that, they are ready for further construction and repair activities (i.e. painting, wallpapering, etc.).
- One of the recommended measures is to stick a non-woven tape over the last layer. This measure will help increase the ability of the corner to resist mechanical damage, i.e. will make it more durable. This is done through the following actions:
- A non-woven tape is glued to the still uncured mixture.
- With the help of a spatula, it is carefully leveled. The putty mixture impregnates the tape through and through.
- Finishing putty is applied.
