Fixing overhead wooden corners at the corners. It's simple - How to fix an arched corner: recommendations of finishers

In order to properly take care of the interior decoration, it is important to pay attention to every detail. Decorating windows and doorways is no exception in this regard. Decorate openings and will give them an aesthetic appearance decorative plastic corner.

He will not only emphasize the clarity of the lines of the corners, but also will hide the imperfections of the plaster, if it was used as a finishing material.

What are these products?

This is a piece of hardware intended for decorative finishing window and other slopes, as well as for hiding corner joints when using different materials.

Corners made of rigid PVC by the method of "hot" bending of the sheet using a special technology.

Scope of application

To make the idea of the purpose of the products more complete, it is worth considering this issue in a little more detail.

PVC corners can be used in the following cases:

Advantages and disadvantages

A plastic slope corner, like any material, has its pros and cons, let's talk about them in more detail.

First, about the advantages of the products:

allow you to close the corner joints of various materials;
smooth out irregularities and form an angle of 90 ° at the finishing points;
service life is 20-25 years;
easy to process during installation;
you can choose the desired color (corners are produced not only white, but also colored)
reasonable price, which favorably distinguishes PVC corners against the background of wooden and metal products.

Minuses:

weak mechanical strength - when cutting, the material may crack in the cutting area, products are easily scratched;
flammability, heated and burning plastic gives off corrosive smoke and gas.

Types and sizes

PVC corners can be divided, guided by two criteria: area of application and type of finish. The main types will be discussed below.

By the nature of the purpose, the products are divided into the following types:

Equilateral. This type is used mainly to give strength to slopes. Available in sizes from 20x20 to 50x50 mm.
Not equilateral. With their help, they decorate arched openings. Sizes - 5x17 and 20x25 mm.
T-shaped products. Most often used to hide the joints between the wall cladding and the slope.
Removable (with a latch). Allows to carry out repair work without resorting to dismantling the profile. If necessary, it is enough to simply bend it, and at the end of the repair, return the shelves to their place.

According to the type of finish, the corners are:

outdoor;
internal;

What kind of glue to use?

One of the most effective options- polyurethane glue. It is possible to use both a special adhesive for plastic corners, and any other composition suitable for the installation of PVC products.

A silicone-based sealant can be used for light-duty areas.

This glue also used to fix corners to ceramic tiles in the kitchen or bathroom.

Another option is liquid nails. When installing light products it is better to use a colorless composition, and any option is suitable for dark products.

How to glue plastic corners to slopes?

Installation of corners should be carried out only after finishing work (wallpapering, painting, etc.). Myself the installation process is carried out in several stages.

The first step is to remove all protrusions from the surface, if any, be it plaster, putty, etc. If wallpaper is glued to the wall, you need to remove it in the places where the corner fits.

Otherwise, it will be glued to the wallpaper and not to the wall. The wallpaper should be cut in such a way that after the installation of the corner, a gap does not form between it and the cladding. Next, you need a place for attaching the corner degrease with a mild solvent or white spirit.

The corner must be attached to the wall and mark it with a pencil- above and below on vertical parts and along the edges on horizontal corners, which will be located between the slopes.

It is advisable to measure the vertical elements after gluing the upper horizontal one, and the lower one after mounting the vertical ones. In this case the risk of gaps formation is reduced between their edges.

By applied marks cuts are made with metal scissors... The inner part of the corners is cut at an angle of 90 °, and the outer part is cut at an angle of 45 °.

The glue is applied with a narrow dotted strip to the inside of the product, closer to the middle, at intervals of 1–1.5 cm.

Next you need attach the corner to the surface and press well, then fix it for a day with masking tape or tape in several places. After the glue is dry, the tape should be carefully removed. This completes the installation.

A huge selection of finishing materials allows you to decorate walls, ceilings, doorways of an apartment or house in the most daring and interesting decor options, but there is one condition. You need to think in advance how to strengthen and protect the corner lines of the walls. The peculiarity of modern wall decoration is such that the outer corners of the walls are the first to age and lose their appearance.

In some cases, you simply cannot do without protective plastic corners for walls, as in the case of facing with tiles or wall panels. Therefore, people who are versed in overhaul issues, when choosing a finish, must look out for plastic corners to protect the corners of the walls.

Where and how are profiles used to protect wall corners

You have to get acquainted with the first version of the profile corner even at the stage of plastering or leveling the surface of the walls with the help of drywall. Installing a plastic corner under the wallpaper makes it possible to solve two problems at once:

Strengthen the finishing layer of putty;
Give the outer corner perfect geometry, at least visually, the line of the junction of the two planes looks quite even.

Anyone who at least once had to glue wallpaper on walls with curved corners will appreciate all the benefits and practicality of the simplest plastic profile.

For your information! With the plastic wall corner, you can easily remove the outer and inner corners even on the most uneven walls.

The main difference between corner profiles and decorative plastic corners is that the mounting option always has perforations along the entire length. The corner does not need to be glued, it is simply imprinted into a layer of putty or plaster. Even professional plasterers always use a plastic corner in their work.

But the use of mounting profiles to level the walls does not solve the appearance problems of the corner edges, both internal and external, especially if the walls are finished with light tapestries. Therefore, plastic corners are often installed in addition to the perforated profile.

What it gives:

Complete corner protection. No matter how carefully the owners handle the decorative trim at the corner joints of the walls, after a few months, a maximum of a year, traces, scratches and chips of the cladding will appear;
Eliminate gaps and gaps between wall panels, especially on wall corners and skirting boards, on a curved surface;
Drastic improvement in appearance. Colored plastic wall corners will help to transform and significantly refresh the wall decor with minimal costs.

In this case, it is not necessary to be limited to the outer corners of the walls, although it is they, as they say, in plain sight and require protection in the first place. Often, a plastic corner at the corner of the wall has to be installed after the fact, it is worthwhile to rearrange the furniture once, with the transfer of the most dimensional interior items. Scuffs and dirt can still be removed or washed off, but chips and deep scratches on the walls have to be hidden.

Internal corners also have to be closed in order to mask the transition from one type of finish to another, for example, when simultaneously lining the walls of the corridor with plasterboard, MDF or DFP panels, and living rooms with wallpaper and wall plates.

Plastic profile for sealing corners

For decorative purposes, corners made of polyvinyl chloride, polystyrene, polyurethane and even silicone are used. If the walls of the room are finished with wood or tiles, then a corner of a similar material will be required; a plastic profile for such a decor looks unnatural. For all other cases, the list of the most suitable materials is invariably headed by the PVC corner, it remains the most in demand. Almost everyone who faced the problem of finishing and protecting the corners of the walls with an overhead profile is unanimous in their choice, this is a PVC profile.

Exceptions are metal and MDF corners used as cover strips that cover the line of the window opening from the street side. At the same time, a plastic outer corner made of polyvinyl chloride is often used for balcony doors.

The reason for the popularity of the PVC profile is determined by three important properties:

Beautiful appearance, there are practically no problems with the selection of the desired shade of colored plastic corners to protect the corners of the walls;
Plastic material is highly flexible and "democratic" during installation. No problems with gluing, as in the case of polystyrene or polypropylene corner profiles;
Easy processing when adjusting the size of the corners. The material can be easily cut with scissors, a bread knife or, best of all, a metal blade.

For your information! Good workability of the material does not exclude the possibility of profile cracking, especially if the plastic corner has been stored for a long time on the balcony or in the garage at low temperatures.

In this case, before cutting the plastic corner, it must be kept for an hour at room temperature.

Size of plastic corners

The advantages of the plastic corner include the low cost of the material. Depending on the height of the shelf, the price of a 2.7 m long strip ranges from 50 cents for a size of 10x10 mm to 1.7 dollars for a profile of 50x50 mm. For cladding home walls and corners, a corner with a shelf of 20 mm and 15 mm is usually used, their cost is in the range of 0.7-1 dollars for a standard strip of 2.7 m.

On the market, PVC profiles are represented by three types of plastic corners:

Standard equal shelf version, in which both shelves are the same size;
Double corner or T-profile used to decorate interpanel and tile seams;
L-shaped or arched plastic corner with different shelf heights.

No matter how the masters try to align the planes of the walls, over time, a gap forms in the corner, which must be somehow masked by installing a plastic corner on the corner of the wall. Otherwise, an ugly line of transition from one type of finish to another will remain. For the case when you need to close the joint between the wallpaper and decorative plaster on the wall, the smallest profile, 10x10 mm, is quite enough. The same shelf size is chosen for the outer corner for the plastic skirting board. The largest profiles, 50x50 mm, are used for installation on the corners of building facades, dimensions 20x20 and 25x25 are the most common for interior work.

Variants of using the corner profile for finishing corners

At first, most apartment owners are rather restrained in using the corner profile when decorating the corners and the line of the wall junction. First of all, the well-established classical opinion that the use of PVC materials in an apartment should be limited and used primarily where it is simply impossible to do without it, interferes. For example, for entrance doors in the bathroom or in the kitchen.

It is possible to destroy distrust in plastic corners only if people see with their own eyes the difference between wall decoration without a corner and after installing a plastic corner profile. The difference in perception, even with the simplest decor, is significant.

Finishing the slopes of doors and windows

The most vivid example of the advantages of installing a corner PVC profile is the windows and doors of a modern apartment.

With the replacement of the old wooden window frame with a double-glazed window, as a rule, it is necessary to plaster the slopes in a new way, to look for a method and material to close the resulting outer corner to the walls of the room.

Traditionally, window slopes are made on the basis of drywall sheets, with a reinforcement of the outer corner with a perforated metal corner, photo.

This makes it possible to perfectly align the planes and achieve the most even angular line, but still the edge will remain a risk zone. The window is used quite often, so even curtains or curtains often cause edge damage. If finishing slopes using MDF or PVC panels, then you simply cannot do without installing a plastic corner on the slopes. First of all, you will need to close the end of the cladding panel, otherwise the entire decorative effect from the use of the finish will be smeared. The dimensions of the plastic corner for the slopes depend on the height and width of the window opening.

A plastic corner for drywall and wallpaper is selected 20x20 mm, for the corner at the transition of MDF plate - wallpaper, an corner profile with a size of 25x25 mm is installed. In the latter case, if you wish, you can hide the installation of the protective profile, for this you just need to choose the right colored plastic corners on the slopes. It is quite difficult to paint polyvinyl chloride, therefore the option with repainting is used if the entire window with slopes and corners is planned for painting.

In addition to finishing the outer edge, it is necessary to install plastic strips between the window frame and the plane of the slopes, as well as close the line of intersection of the window sill with the walls. For these purposes, it is best to use a T-shaped profile with a deflection in the central part.

At first glance, the line of intersection of the slope and the window sill may not be covered with a plastic corner, but this is not entirely true. The plastic window sill springs quite strongly even under a slight load, therefore, after a few months, the material with which the corner joint is sealed may simply spill out of the gap, so it is better to close it with a corner profile in advance.

The same plastic corners are often used for decorative sealing of the seam line between the bathroom and the tiled wall. PVC is ideal for wet bathroom environments.

The second section of the walls, where it is almost impossible to do without installing a decorative plastic corner, is the entrance doors. If the entrance doors are changed in a house or apartment, this means that the owners have a large front of work on finishing and decorating the vestibule and door slopes. Since the front door always remains the most dusty place in the house, the slopes of the doorway, with rare exceptions, are traditionally finished with MDF, clapboard and PVC panels, most often imitating wood or natural stone.

After the walls of the door vestibule are plastered and putty, you can lay the cladding. Any master can confirm that after finishing work on the angle of intersection of the corridor walls and the plane of the slopes, the ends of the facing panels will remain visible. They must be closed in order to achieve a complete appearance of the doorway and to exclude the accumulation of dirt and dust in the cracks.

If the vestibule was lined by direct sticking of PVC tiles or panels on a plastered surface, then a plastic corner with a shelf width of 30 mm would be enough to close the cracks. For decorative finishes laid on a pre-filled batten or galvanized profile, a 40-50 mm corner plastic profile is required.

Arched doorways

Among the many design options for the interior opening, the arched scheme is considered one of the most beautiful and expressive. The arch is most often assembled on the basis of a metal frame with plasterboard lining, or laying out of light wall foam blocks.

One of the problems that one has to face when assembling an arch arc is related to the inflexibility of drywall and galvanized profiles. Both are almost impossible to bend with a smooth curve. In order to get an arc, the supporting frame has to be recruited from a dozen short segments - chords. The filing of the inner surface of the arch is also recruited from short pieces of drywall.

You can simplify the task, for this, the arch trim with a plastic corner is performed in the form of several rectilinear sectors, photo.

There are two ways to solve the problem of the smoothest profiling of the arch:

Installing a finished arched plastic corner photo. You only need to adjust the dimensions of the opening to the finished profile, install and fix the polypropylene frame;
Run drywall wall sheets with a curved arc cut out according to the template. The inner part of the slope is blown out with polyurethane foam, and the edge is sheathed with a decorative plastic arched corner.

The use of a decorative plastic profile allows you to close the joint and the corner transition from drywall to the slope. This way of arranging an arched passage is cheaper and easier. But there is one condition, you need to know exactly how to bend the plastic profile under the arch. At first glance, it is not difficult to bend a soft PVC profile. One of the simple descriptions of how to bend a plastic corner onto an arch is shown in the video

An ordinary plastic corner is not suitable for these purposes. Any attempt to stick or nail it to the edge of the drywall leads to the fact that in the upper part the decorative profile moves away from the wall and breaks into two parts. You have to cut one of the shelves of the usual corner into segments 25-30 mm long or, more conveniently, use a special plastic corner for the arch.

Most often, a 17x5 mm profile is used for an arched doorway. Due to the reduced side shelf of the plastic profile, the corner bends practically without distortion, which means that when laying the material on glue, the risk of delamination from the edge of the wall will be minimal.

If the radius of the arc of the arched opening is small enough, the plastic profile has to be bent so much that even a special decorative corner begins to warp. In this case, you can use the "hot" method of bending. The corner is fixed at one end of the arch with a clamp or clamp. Then the PVC profile is heated with a hairdryer to a temperature of 60-70 ° C and pressed against the edge of the drywall. While the material cools down, it is rolled into place using a soft paint roller.

Advice! If it was not possible to bend the desired arc profile in two or three warm-ups, then bending must be stopped, since the material becomes hard and brittle after several heating cycles.

Before gluing the plastic corner to the arch, it is necessary to determine the points of contact of the profile to the surface of the walls, in order to apply the glue exactly in these places. If you do this blindly, most of the adhesive applied to the plastic profile will be wasted.

DIY installation of a plastic corner

The process of laying a decorative profile at a corner or on the edge of an arch is not difficult; it requires careful and careful handling of plastic. PVC is easily scratched and loses its glossy shine. Often, the front of the plastic corner is sealed with paper to avoid damage and contamination with glue. After the adhesive base hardens, the corner surface can be polished with a soft cotton cloth.

One of the advantages of using a PVC profile is the fact that during production, the material is colored throughout the entire mass, any scratches and abrasions do not lead to a change in color or shade. So you can polish the material an infinite number of times.

How to glue a profile on a corner joint

Working with a corner profile is no different from similar operations with polyurethane glazing beads or skirting boards. Initially, before gluing the plastic corners to the slopes, you need to do a little preparatory work.

First, measure the length of the PVC profile with a tape measure for each slope angle. Since the window opening has a rectangular shape, all plastic corners will be joined together at right angles. The joint line will be cut at an angle of 45 degrees. For other structures - arches or polygonal vaults, the angle of the cut will need to be determined at the place of the sticker.

After marking, you need to cut off the plastic strips according to the measurements. This should be done as carefully as possible, since the corner is quite thin, only 1-1.5 mm, so the material can be easily split if not cut correctly.

Experienced craftsmen cut the profile with a construction knife under a ruler or well-sharpened scissors. If you do not have adequate cutting experience, then it is better to use a joiner for corner cuts. PVC is ideally cut with a regular hacksaw blade.

After cutting, we carefully remove the burrs and perform a final fitting of the cut blanks at the place of the sticker. To do this, you need tape and a building level. Attaching the blank of the plastic corner to the gluing site, align its position in level and fix it with several strips of adhesive tape. Install the upper corner strip in a similar way.

Only by setting all the cut-out sections of the corner "roughly" and aligning them to the building level, it becomes clear how correctly the corner was cut. Usually, for amateurs, a gap of 1-3 mm wide is formed at the joint line. It is clear that you cannot glue a plastic corner with such slots.

Advice! When cutting the corner profile, add an allowance of 2-3 mm to the calculated size. This margin when fitting will help correct the situation without much consequence.

To get rid of cracks at the joints of the walls, you will need to once again clarify the passage of the cut line along all three blanks. To do this, draw a correction line with a pencil and disassemble the structure to adjust the corners. The line can be cut with scissors or sharpened with a piece of sandpaper wrapped around a block of wood.

How and what to glue

It remains to glue the plastic corner on the corner edge of the slope. First of all, you need to choose how to glue the plastic corner to the wall. In salons and hardware stores, the adhesive composition "Liquid nails" will be recommended as the most suitable tool. Of the positive characteristics, only convenient packaging in the form of a tube can be called.

Everything else is on the conscience of the manufacturer. This compound can be used to glue lightweight polyurethane bovelacchi or a plastic corner 10x10 mm in size on the tile joint. In addition, the white glue mass over time becomes beige-gray, so traces of glue are very clearly visible at the seams and joints.

Slopes on windows, on entrance doors must be glued with silicone, it can be transparent, but if you wish, you can easily choose a colored version of the sealant. Not all adhesives adhere well to the smooth surface of the PVC corner. Silicone sealant is a welcome exception, it does not drip or shrink.

But the main advantage is getting a strong and elastic seam. If you have to glue something on the doorframe, on lightweight partitions that vibrate with every slam of the doors, choose silicone. Any other adhesives that give the strongest and toughest seams cannot withstand vibrations and chip, especially when it comes to a plastic corner.

The technology for gluing a corner plastic strip is quite simple. Apply glue in thin lines to the inner surface of each of the shelves. If the glue is very thick, then the glue mass can be applied to the wall with short oblique lines or dots. Do not cover the entire wall surface with a continuous layer. Firstly, such a plastic profile will be impossible to press into place, and secondly, 50% of the adhesive mass will be squeezed out uselessly outside the corner. Too liquid glue will simply run out from under the plastic strip.

Carefully place the prepared plastic corner with the applied glue in place of gluing. To make the glue seam strong, you need to gently press the bar into place. A small amount of glue mass can be squeezed out from under the plastic profile, but do not rush to remove it - first you need to align the corner. The PVC profile is very flexible, and it will not be possible to trim it with your hands, therefore, the laid corner is brought to a rectilinear state using a metal ruler and a building level. To prevent the plastic corner from falling off the wall and sliding down until the glue completely dries, you need to fix it with several strips of adhesive tape.

We glue the next strip of the plastic profile in the same way, but before laying in place, you will need to apply a small amount of glue to the joint line. After settling, part of the glue will come out at the joint, all excess can be removed only after the glue mass has completely dried. While the glue is still wet, any attempt to remove excess glue will stain the wallpaper.

Sometimes there is a problem with the length of the arched corner. The maximum length of the plastic strip is 3 m. This may not be enough if the arched opening is made for the entire width of the room, the length of the corner profile on such an arch can reach 3.5-4 m. In this case, the arched arc has to be finished with a small piece. It is best to make the central part of the arc solid, add two small segments on the sides, and seal the joint line with silicone sealant in the color of the plastic material.

After a couple of years, due to shrinkage processes, the seams may disperse a little, but all the same, the arch will retain its original effect. If you increase the length of the plastic corner on one side, then the joint will be perceived as a stain and spoil the impression of the whole structure.

Conclusion

Plastic corners are successfully used not only for residential premises. For example, for a summer cottage or a bath, sheathed with clapboard, for a country house made of timber, the protection of the corner joints of the outer walls is always relevant. This is not so much a question of the aesthetics of the appearance of the building, as an urgent need for protection against moisture penetration. In this case, under the plastic corner of 50x50 mm, two supporting wooden slats are packed, on which the plastic corner profile is glued.

Plastic corners for slopes are the logical completion of the renovation in the house. They act as a protective and aesthetic design for doorways, window slopes and corners.

Today we will look at how to glue the plastic corners to the slopes with our own hands and the better to glue the plastic corners to the door slopes.

Scope of use and additional information

The framing corner is made by hot folding the PVC sheet. The decorative element makes it possible to choose colors that suit any interior. Application area:

Window slope inside a house or apartment.
As an external material to protect external or internal corners.
Door or arched opening.
To protect the corner of the wall when wallpapering.
Corner protection when finishing with plastic in the bathroom.
Drapery of the joint when decorating the external cladding with siding.

A plastic element is a good protector against mechanical stress, but, like any material, it has advantages and disadvantages:

The installed corner is used as a finishing of the seam at the junction of the finishing materials.
Long service life - up to 25 years.
Installation is carried out independently, you can glue the corner without preliminary preparation.
The plastic element is easy to cut and comes in different colors.
Acceptable price.

Among the shortcomings, the following turned out to be significant:

Plastic is a fragile material, so it must be cut with special tools - cracks may appear.
The combustible finishing element does not tolerate high temperatures.

Compare types and sizes

Framing always starts with choosing the type and size of the plastic element. The table shows data about plastic corners, their sizes and types for slopes:

View:	The size:
Equilateral:	20 * 20 - 50 * 50 mm, standard length, fixed to give strength.
Not equilateral:	5 * 17 and 20 * 25 mm, facing of arch openings, it is customary to install on curved compositions.
T-shaped:	12 * 10, 18 * 10, 20 * 10, 22 * 10 mm, installation is necessary to hide the seams.
Removable (there is a latch):	Standard, the shelf is folded back for dismantling. Simple fastening, no need to stick.

During installation, you need to cut the corner to form the desired length. A sharp stationery knife will help with this. If you need to cut at a clear angle, you will need to prepare a miter box and a hacksaw for metal.

Important! The colored plastic corner for internal slopes is produced in lengths of 2.6 m, 2.7 m, 2.8 m, 3.0 m.

How to glue plastic corners to slopes (video)

Preparatory work

The installation process begins with the selection of the adhesive mixture. Polyurethane glue fixes plastic elements well, allows you to frame surfaces where there will be a load. It makes it possible to glue the details in the bathroom if ceramic tiles are glued.

The silicone sealant is used as a fixer with less stress. The corner can be glued with the help of liquid nails, if the edging is dark in color, then it can be glued with the help of black composition, for light and white - transparent.

Installation of plastic corners

The work on installing plastic corners on slopes is as follows:

Regardless of where you need to glue the plastic corners - on the door, if the casing or window is not provided, outside or inside, you need to make measurements and cut the material to length correctly.
Prepare the surface where gluing will take place - remove unnecessary elements, clean the base.
Install and glue the strips correctly.

How to properly glue plastic corners on any slopes:

Degrease the surface well before attaching the corner piece.
Polyurethane foam is not used in the design process.
Excess protruding plaster is smoothed out to a noticeable smoothness.

The sticker provides for marking with a pencil.
Before you glue all the details, you should use the advice: it is better to measure the corners for the slopes of doors and plastic windows locally. First of all place the top horizontal element, and then use the cutting tool to mark the vertical stripes.

Important! Using photos and videos, each beginner will cope with the gluing process on their own. The metal element is also fixed with self-tapping screws.

Sheathing with corners also implies additional fastening of the strips using narrow masking tape. Fix the strip with it in several places and leave it for about 24 hours. This time is enough to reliably glue the corners to the surface.

If the corner is used as a finish, then the place of its gluing should be cleaned of finishing materials. Thus, the grip quality is increased. When fixing on an area decorated with trellises, a strip should be cut a couple of millimeters wide than the plastic corners. Adhering to simple design rules, fixing decorative elements will be simple and quick, and in the end they will delight you with an aesthetic and relaxed look.

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

Existing types of drywall corners

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

The following product options are most common:

Metal perforated corner

This view is a thin sample from a profile with perforation and a rigid edge along the edge. Basically, there are 2 types of similar drywall corners:

straight;
arched.

These representatives have many subspecies. The corners are not glued, they are practically "pushed" onto the structure and fixed with putty or.

The straight perforated corner is used to machine the inside and outside of corners.

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

Metallic Perforated Drywall Corner Options

Actually, with their help, a high-quality connection with the corners to be processed occurs, and the top located at the inner corners - inside, and at the outer corners - outside, is a guide for the spatula. Excess air also comes out through the holes. Straight perforated corners are plastic, aluminum, 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 from the profile, but the resistance to mechanical damage is lower. Of the advantages, it is possible to note the low price and the absence of material corrosion. There is also a type of plastic corner, for example, AquaBead, which has special paper with glue applied in the inside. Putty for fixing is not required here, it is enough to moisten the glue surface with water and just glue the corner to the desired place.

Arched

Various finishing materials are used, such as plaster, wallpaper, panels and others. But in order to save the places of transitions between the planes, an arched corner is used, which has great capabilities. Arched corners are divided into the following types:

Installed under plaster, perforated. They have separate petals on one side of the corner, allowing sufficient strip to be placed on any arched bend. There are plastic and from the profile;
Decorative, glued to plaster.

Products with mesh

Similar elements are used in places requiring reinforcement of corners and protection from damage. Plaster mesh corners are designed for internal and external corners. They can be made of either plastic or metal profiles. The choice will be influenced by the shape and material of the plane for finishing.

Installation of corners on drywall using corners

When starting to install the 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 a certain margin;
by using ;
it is best to buy Vetonit putty, which is of high quality.

Instruments

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

This is how the mounted corners look on drywall

Before starting the installation, it is necessary to familiarize yourself with the sequence of aligning the corners with a putty, so as not to damage this fragile material.

Stages of work

First, the plane must be thoroughly cleaned and primed. 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 drywall as a fitting.
For further work, you will need a non-woven tape, a serpentine mesh - for inner corners, one of the types of perforated corners: plastic, adhesive, rounded or made of a metal profile or on a paper base.
Before making a choice. For the formation of internal and external corners, it is better to buy a dry gypsum mixture. It has a reasonable price, good quality and can reliably fix the elements to the structure.
Prepare the putty in compliance with all stages: pour it in, pour it, stir it, let it settle, knead it again.
When working with external corners, you need to remember that they are most often exposed to mechanical stress, it is better to fasten metal samples, in some cases having a rounded shape.
Check the flatness of the end.
Putty is applied to the treated area with smooth movements. Without allowing the composition to dry out, you need to fix the corner with pressure, check the accuracy with a level, if necessary, you can knock 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 it is aligned with the general plane of the wall.
Applying the second layer of putty
After thorough drying, the slope corner is sanded.
The installation of the corners inside the structure looks similar, even a little easier. The adjoining sides, the gap between the corners are thoroughly smeared with a spatula, the excess mixture is removed. On a dry, sanded surface of the desired shape. You can buy it and just put it on a damp putty.
check the attachment to the drywall of the corner, then hide the irregularities with the next layer.
After thorough drying, the surface is finished with sandpaper or a polished bar, while 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 does not have an acute angle, but a semicircular one. Its price is quite reasonable, and its durability is not in doubt. It differs in some features at the installation stage, namely, by trimming 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, the edges are processed with a mixture.

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

Finishing the inside and outside corners will not seem difficult with the right approach and the necessary training. The main thing is that during installation there should be those requiring minimal finishing.
