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

To properly take care of interior design, it is important to pay attention to every detail. Finishing windows and doorways is no exception in this regard. Decorate openings and give them an aesthetic appearance. decorative plastic corner.

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

What are these products?

This is a piece of furniture for decorative finishing window and other slopes, as well as to hide corner joints when using different materials.

corners made from rigid PVC by the method of "hot" inflection 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

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

First, about the pros of products:

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

Minuses:

weak mechanical strength - when cutting, the material may crack in the cut area, the products are easily scratched;
combustibility, heated and burning plastic emits acrid smoke and gas.

Types and sizes

PVC corners can be split, based on two criteria: area of application and type of finish. The main types will be discussed below.

According to 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 perform the decoration of arched openings. Dimensions - 5x17 and 20x25 mm.
T-shaped products. Most often used to hide the joints between wall cladding and slope.
Removable (with latch). Allow to carry out repair work without resorting to the dismantling of the profile. If necessary, it is enough to simply bend it, and at the end of the repair, return the shelves to their place.

By type of finish, the corners are:

outdoor;
internal;

What glue to use?

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

When finishing areas with low traffic, you can use a silicone-based sealant.

This glue is also used for fixing corners to ceramic tiles in the kitchen or in the bathroom.

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

How to glue plastic corners on slopes?

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

First of all, you need remove all protrusions from the surface, if any, be it plaster, putty, etc. If wallpaper is pasted on 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 installing the corner, there is no gap between it and the cladding. Next, you need a place to mount the corner degrease with a mild solvent or white spirit.

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

It is advisable to measure the vertical elements after gluing the upper horizontal, and the lower - after mounting the vertical ones. In this case reduces the risk of gap formation between their ends.

According to the labels 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 in a narrow dotted strip on 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 dries, 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, protective plastic wall corners are simply indispensable, as in the case of tiling or wall panels. Therefore, people who are knowledgeable in major repairs, choosing a finish, be sure to look after plastic corners to protect the corners of the walls.

Where and how profiles are used to protect wall corners

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

Strengthen the finishing layer of putty;
To give the outer corner an ideal geometry, at least visually, the junction line of the two planes looks quite even.

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

For your information! With the help of a wall plastic corner, you can easily bring out 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 mass. Even professional plasterers always use a plastic corner in their work.

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

What does it give:

Complete corner protection. No matter how carefully the owners treat 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 lining will appear;
Eliminate cracks and gaps between wall panels, especially at wall corners and skirting boards, on curved surfaces;
A radical improvement in appearance. Colored plastic corners for walls will help to transform and significantly refresh wall decor at minimal cost.

In this case, it is not necessary to be limited to the outer corners of the walls, although it is they, as they say, that are in sight and require protection in the first place. Often, a plastic corner on the corner of the wall has to be installed after the fact, it is worth rearranging the furniture once with the transfer of the most dimensional interior items. Scuffs and dirt can still be removed or washed, 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, while lining the walls of the corridor with drywall, MDF or DFP panels, and living rooms with wallpaper and wall slabs.

Plastic profile for sealing corners

For decorative purposes, corners made of PVC, polystyrene, polyurethane and even silicone are used. If the walls of the room are finished with wood or tiles, then you will need a corner made of a similar material; a plastic profile for such a decor looks unnatural. For all other cases, the list of the most suitable materials invariably leads 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 overlay profile is unanimous in their choice, this is a PVC profile.

The exceptions are metal and MDF corners used as flashings, covering the line of the window opening from the side of the street. 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 cut without problems with scissors, a "bread" knife or, best of all, with a sheet of metal.

For your information! Good machinability of the material does not exclude the possibility of profile cracking, especially if the plastic corner has been stored for a long time on a balcony or in a 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 plank 2.7 m long ranges from 50 cents for a 10x10 mm size to $1.7 for a 50x50 mm profile. 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 for a standard bar of 2.7 m.

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

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

No matter how hard the craftsmen try to align the planes of the walls, all the same, over time, a gap forms in the corner, which must somehow be 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 wallpaper and decorative plaster on the wall, the smallest profile, 10x10 mm, is quite enough. The same size of the shelves is selected for the outer corner for the plastic plinth. The largest profiles, 50x50 mm, are used for installation at the corners of building facades, sizes 20x20 and 25x25 are the most popular for interior work.

Options for using a corner profile for finishing corners

At first, most apartment owners are rather reserved about the use of a corner profile when decorating corners and the junction line of walls. First of all, it is 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. For example, for entrance doors in the bathroom or in the kitchen.

It is possible to destroy distrust of 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 obvious example of the advantages of installing a PVC corner profile are the windows and doors of a modern apartment.

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

Traditionally, window slopes are made on the basis of drywall sheets, with the outer corner reinforced 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 damage to the edge. If finishing the 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 of using the finish will be smeared. The dimensions of the plastic corner for slopes depend on the height and width of the window opening.

A plastic corner for drywall and wallpaper is selected 20x20 mm, for a corner at the transition of an MDF plate - wallpaper sets a corner profile measuring 25x25 mm. In the latter case, if desired, you can hide the installation of a protective profile, for this you just need to choose the right colored plastic corners for the slopes. Polyvinyl chloride is quite difficult to paint, so the repainting option 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 flashings 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 small load, so after a few months the material with which the corner joint is sealed can 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 damp bathroom environments.

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

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

If the lining of the vestibule was carried out by directly sticking PVC tiles or panels onto a plastered surface, then in order to close the gaps, a plastic corner with a shelf width of 30 mm will suffice. For a decorative finish laid on a pre-stuffed crate or galvanized profile, you will need a corner plastic profile 40-50 mm in size.

arched doorways

Among the many design options for an 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 lined with plasterboard sheets, or laid out from lightweight wall foam blocks.

One of the problems that one has to face when assembling an arched arc is related to the inflexibility of drywall and galvanized profiles. Both of them are almost impossible to bend in 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 decoration of the arch with a plastic corner is performed in the form of several rectilinear sectors, photo.

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

Installing a finished arched plastic corner photo. It will only be necessary to adjust the dimensions of the opening to the finished profile, install and fix the polypropylene frame;
Run the overlap of 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 slope. This method 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, bending a soft PVC profile is not difficult. 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 results in the decorative profile moving away from the wall at the top and breaking into two pieces. You have to cut one of the shelves of a regular 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 almost without distortion, which means that when laying the material on the adhesive, 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 arching. The corner is fixed at one end of the arch with a clamp or clamp. Next, the polyvinyl chloride profile is heated with a hairdryer to a temperature of 60-70 ° C and pressed against the edge of the drywall. While the material is cooling, it is rolled into place with a soft paint roller.

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

Before gluing the plastic corner on the arch, it is necessary to determine the contact points of the profile to the wall surface in order to apply glue in these places. If you do this "blindly", most of the adhesive material applied to the plastic profile will be used up uselessly.

Do-it-yourself plastic corner installation

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

One of the advantages of using a PVC profile is the fact that during production, the coloring of the material occurs throughout the 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 stick a profile on a corner joint

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

First, with a tape measure, we measure the length of the PVC profile for each slope angle. Since the window opening has a rectangular shape, all plastic corners will be joined together at a right angle. We will cut the junction line at an angle of 45 o. 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 taken. 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 it is cut incorrectly.

Experienced craftsmen cut the profile with a construction knife under the ruler or well-sharpened scissors. If there is no relevant cutting experience, then it is better to use a carpentry tool for corner cuts. PVC is ideally cut with a conventional hacksaw blade.

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

Only by setting all the cut-out segments of the corner “roughly” and aligning them with the building level, it becomes clear how correctly the corner was washed down. Usually, for amateurs, a gap of 1-3 mm wide forms on the junction line. It is clear that it is impossible to glue a plastic corner with such slots.

Advice! When cutting a corner profile, add an allowance of 2-3 mm to the calculated size. This margin, when fitted, will help correct the situation without any special consequences.

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

How and what to glue

It remains to stick 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 liquid nails adhesive composition will be recommended as the most suitable means. Of the positive characteristics, only convenient packaging in the form of a tube can be called.

Everything else - on the conscience of the manufacturer. With this composition, you can glue light polyurethane bovelacchi or a plastic corner measuring 10x10 mm to the tile joint. In addition, the white adhesive mass becomes beige-gray over time, so traces of glue are very clearly visible on the seams and joints.

The slopes on the windows, on the entrance doors must be glued with silicone, it can be transparent, but if desired, you can easily choose the color version of the sealant. Not all adhesive materials adhere well to the smooth surface of the PVC corner. Silicone sealant is a pleasant exception, it does not drip or shrink.

But the main advantage is in obtaining a strong and elastic seam. If you have to stick something on a door frame, on light partitions that vibrate with every slamming of the doors, choose silicone. Any other adhesives that give the strongest and toughest seams do not withstand vibrations and chip off, especially when it comes to a plastic corner.

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

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

We glue the next plastic profile bar in the same way, but before laying it in place, it will be necessary to apply a small amount of glue to the joint line. After precipitation, part of the adhesive will come out at the joint, all excess can be removed only after the final drying of the adhesive mass. Until the glue has dried, any attempt to remove excess glue will result in stains on 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 diverge a little, but still the arch will retain its original showiness. If you increase the length of the plastic corner on one side, then the junction 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 dacha or a bathhouse lined with clapboard, for a country house made of timber, protection of the corner joints of the outer walls always remains relevant. This is not so much a matter of aesthetic appearance of the building as an urgent need for protection from moisture penetration. In this case, under the plastic corner 50x50 mm, two load-bearing wooden slats are stuffed, on which the plastic corner profile is glued.

Plastic corners for slopes are the logical completion of repairs 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 plastic corners on the slopes with our own hands and the better to glue plastic corners on the door slopes.

Scope and additional information

Corner for framing is made by hot bending PVC sheet. The decorative element makes it possible to choose colors that are suitable for any interior. Application area:

Window slope inside the house or apartment.
As an outdoor material to protect external or internal corners.
Doorway or archway.
To protect the corner of the wall when decorating with wallpaper.
Protecting corners when finishing with plastic in the bathroom.
Drapery of the joint when decorating the outer cladding with siding.

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

The installed corner is used as a seam finish at the junction of finishing materials.
Long service life - up to 25 years.
Installation is carried out independently, you can stick the corner without prior preparation.
The plastic element is easy to cut, available in multi-colored.
Acceptable price.

Significant shortcomings included:

Plastic is a brittle 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 begins with the choice of the type and size of the plastic element. The table shows data about plastic corners, their sizes and types for slopes:

View:	Size:
Equilateral:	20 * 20 - 50 * 50 mm, standard length, attached to give strength.
Not equilateral:	5 * 17 and 20 * 25 mm, lining of arch openings, it is customary to install on curvilinear compositions.
T-shaped:	1210, 1810, 2010, 2210 mm, installation is necessary to hide the seams.
Removable (there is a latch):	Standard, the shelf is bent for dismantling. Easy to mount, no sticking required.

During installation, it is required to cut the corner to form the desired length. A sharp utility 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 available in lengths of 2.6 m, 2.7 m, 2.8 m, 3.0 m.

How to glue plastic corners on slopes (video)

Preparatory work

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

Silicone sealant is used as a lighter load retainer. The corner can be glued with liquid nails, if the edging is dark, then it can be glued with a black compound, for light and white ones it is 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 there is no platband or window, outside or inside, you need to take measurements and cut the material correctly to length.
Prepare the surface where the gluing will take place - remove unnecessary elements, clean the base.
Install and properly glue the strips.

How to glue plastic corners on any slopes:

Degrease the surface well before attaching the corner piece.
Mounting foam is not used in the design process.
Excess protruding plaster is cleaned to a tangible 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 in place. First of all, install the upper 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 the help of corners also implies additional fastening of the strips using narrow masking tape. Fix the band with it in several places and leave it for about 24 hours. This time is enough to securely 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 quality of adhesion is increased. When fixing to an area decorated with trellises, you should cut a strip a couple of millimeters less wide than the plastic corners. By adhering to simple design rules, fixing decorative elements will be simple and fast, and in the end they will please you with an aesthetic and relaxed look.

Corner for drywall 25x25 mm galvanized - 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. However, prefabricated ones have problem areas - corners, which are most often subject to mechanical stress. This is where various types of existing corners will come to the rescue.

Existing types of drywall corners

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

The most common product options are:

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 corners for drywall:

straight;
arched.

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

The straight perforated corner is used for processing the inside and outside of the corners.

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

Variants of metal perforated corner for drywall

Actually, with their help, a high-quality connection with the processed corners takes place, and the top, located at the inner corners - inside, and at the outer corners - outside, is a guide for the spatula. Excess air also escapes through the holes. Straight punch angles are plastic, aluminum, galvanized. The latter is tougher than 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, one can note the low price and the absence of corrosion of the material. There is also a type of plastic corner, for example, AquaBead, which has a special paper with glue applied in the inside. Putty for fixing is not required here, it is enough to moisten the adhesive surface with water and simply glue the corner to the right place.

Arched

Various finishing materials are used, such as plaster, wallpaper, panels and others. But in order to preserve the transition points between the planes, an arched corner is used, which has great potential. 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 bend. There are plastic and from the profile;
Decorative, gluing of which occurs on the plaster.

Mesh Products

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

Mounting 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 bought with some margin;
via ;
it is best to buy Vetonit putty, which is of high quality.

Instruments

metal scissors will help to correctly and quickly cut the necessary parts;
brush, which is required for applying the primer;
wide and narrow spatulas will be needed for;
the grinding block will remove all the irregularities on the plane, while the angle will be perfectly even.

This is how the mounted corners on drywall look like

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

Stages of work

First, the plane 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 desired length of the corners is cut off. 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 from a metal profile or paper-based.
Before you make a choice. For the formation of internal and external corners, it is better to buy a dry gypsum mix. It has an affordable price, good quality and will be able to securely fix the elements on the structure.
Putty is prepared in compliance with all stages: poured, poured, stirred, allowed to settle, kneaded again.
When working with external corners, it must be remembered that they are most often subjected to mechanical stress, it is better to fasten metal samples, in some cases having a rounded shape.
Check the evenness of the end.
Putty is applied to the treated area with smooth movements. Not 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 coat of putty
After thorough drying, the sloping corner is polished.
Installing the corners inside the structure looks similar, even a little easier. The adjacent sides, the gap between the corners are carefully smeared with a spatula, and the excess mixture is removed. On a dried polished surface having the desired shape. You can buy and, only put it on raw putty.
check the fastening on the drywall of the corner, then with the help of the next layer hide the irregularities.
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 fasteners.
Separately, I would like to mention a semicircular plastic corner used in rooms with the maximum possible impact on the corners. It is made of flexible plastic and has not an acute angle, but a semicircular one. Its price is quite acceptable, 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, the edges are processed with a mixture.

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

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