Finishing the oblique corners of the beams in the apartment. Finishing the corners in the apartment with decorative corners. Universal Corner Finishing System

Finishing the corners in the apartment has various options for its implementation. There are also two types of corners that can be finished. For this, a large number of modern materials. How the facing of the corners is made, let's consider in more detail.

Varieties of corners in the room that can be finished

Ways to finish the corners are quite diverse. They are based on what kind of corner is made and what material the walls are decorated with (see Wall finishing options).

All corners in the room can be:

Internal.
outdoor.

Most often, decorative trim is performed on the outer corners, as they are most susceptible to rubbing. This is a kind of protection of the main finishing material from deformation along the edges of the finish. Internal corners in the decoration of the whole room and do not require special decoration.

Advice. It is necessary to decorate the internal corners in the room only if it is required by the design of the room from www.24siding.ru.

For example, completely two walls are processed decorative plaster, and the inner corner is decorated with decorative stone or ceramic tiles. The photo shows examples of the design of internal corners according to interior design.

How can I arrange the outer corners in the room

How to finish the corners in the apartment? Everything is very simple for this today a large number of modern materials. You can use ready-made fixtures for this or make the facing of the corner surface yourself.

Finished fixtures are presented in the form:

Plastic profiles with a straight corner radius.
Plastic corners.
Styrofoam or wooden corners.

All of them are quite easy to install and are able to decorate any finish.

Plastic profiles and corners for finishing external corners

Plastic profiles for finishing wall corners can be used both on external and internal structures. They are universal, as they are mounted on the surface of any finishing material.

Advice. For facing internal corners, profiles and corners should be used only if using plaster or other means it is not possible to make the corner perfectly even.

They are moisture resistant and are not able to react with deformation to temperature changes. They are very practical and reliable. Dirt and dust are not absorbed by their surface, due to which there is a quick and easy cleansing.

The dimensions and appearance of such devices are quite diverse. There are the following surfaces of corners and profiles:

Smooth or rough.
Glossy or matte.

The color range of the material is also quite large and it will not be difficult to choose the necessary shade for decorating the surface of the corners.
The length of the profile or corner is at least 250 cm. The width starts from 1 cm and ends at 10 cm.
They do not burn, but can only melt under the influence of a temperature of at least 150 degrees. They are used freely in damp rooms and where there are temperature differences.

They are considered environmentally friendly, since various harmful chemicals are not used in the production of profiles and corners.

Styrofoam corners

Very often, the decoration of the corners of the walls in the apartment is carried out with polystyrene foam corners. They are quite practical and durable. The surface of the material is represented by various reliefs. They are very light and will not put extra stress on the entire finish.

So:

The material does not absorb moisture and dirt.
Does not burn and can be used in any room with any temperature regime because they are not afraid of temperature fluctuations.

They are made of expanded polystyrene, by pressing under the influence of high temperatures. They have a wide range of colors.
The main advantage of styrofoam corners is that they can be painted.

Advice. With a high passability of the room or with a very small square of it, such corners are not recommended for use in decoration, since they are not resistant to abrasion and deformation. With an inaccurate turn, the structure of the corner breaks quite quickly and simply, thereby spoiling the appearance of the corner.

Finishing the corners in the apartment with the corners of their polystyrene foam is simple and liquid nails are used for this.

Wooden corners for decoration

How to design corners with wooden structures quite common in the wooden decoration of the room. There are both internal corners made of wood and external ones. They have a very attractive appearance. There may be carvings or other decoration on their surface.

Advice. Since such elements are sold ready-made and their surface is not varnished, it will definitely be necessary to paint it before installation. Such actions are also performed after the installation of the element, but only if the main decoration of the room is not completed.

The price for them is quite high. All this is due to the environmental friendliness of the material. They are very durable and reliable. The color scheme is limited only to shades of natural wood.

Note. To darken the shade of the material are used special means, which not only change the color of the material, but also give it special strength and moisture resistance.

It is not recommended to use wooden corners in rooms where there is high humidity and sudden temperature changes. The structure of the tree is designed in such a way that it is able to absorb moisture and at the same time deform (cry out and shrink).

How to mount plastic, polystyrene and wooden decorative corners

All work is easily done by hand, and for this you need to carry out preparatory work on the surface of the corner. They include leveling the corners even before the main finishing of the room.

This is done in two ways:

The use of drywall.
Application of plaster.

Let's take a closer look:

To use the plaster on the corners there is an instruction. In this case, not only the main types of plaster are used, but also metal corners, which are pre-mounted on the surface of the corner and help to make the corner even. The process is quite lengthy and laborious.
The use of drywall to level any surface is characterized by the speed of work. The material is used for both external and internal corners.

How to level corners with drywall

Finishing outside corners drywall is currently very popular.

There are two ways to mount such material on a surface:

On the frame.
Without him.

Advice. Finishing the outer corners of drywall should be done in the same way as the alignment of the walls in the room. That is, if the wireframe method is used, then the angle should also be using the wireframe. This will make the surface around the perimeter of the room in the same plane.

Carrying out work:

If you opt for the frame method of fastening the material, then initially a crate is made with the help of special metal profiles. It is fastened with dowels to ensure a secure fit.
Sheets are mounted to the frame with self-tapping screws. The joints of the material are puttied with a small layer and processed after complete drying with sandpaper. Now on the drywall surface, you can perform a fine finish.

Advice. For such work, it is better to prime drywall sheets for a stronger bond between the finish and the surface.

Drywall finishing of external corners without the use of a frame is considered simpler and more practical. For mounting sheets of material, a special glue is used. It is applied to the back side of the GLK, and the material is pressed tightly.

Advice. Before such work, the surface of the corner must be prepared: cleaned and primed.

Joints of sheets or open cuts must also be puttied. The surface of such an angle is also primed.
Drywall has one drawback - its surface does not have an attractive appearance and it is used only for rough finishing.

Advice. Be sure to veneer the plasterboard surface with another finishing material.

Methods for finishing plasterboard corners

Options for finishing the corners of plasterboard are quite diverse. Here you can use various modern finishing materials:

Ceramic tile.
Plastic panels.
Natural or decorative stone and other materials.

Finishing the corners with ceramic tiles is done using:

A tile cutter that cuts material very quickly.
Building level, which ensures smooth installation of each finishing element.

Special glue or concrete mortar.
Ceramic corners, which serve as the basis for mounting tiles on the corners.

Execution of works:

Decorative putty masks masonry seams ceramic tiles. It is possible to use decorative corners on top of such a finish in case of uneven laying of tiles. They are attached to the surface of ceramic tiles with a sealant or a special adhesive. Most often, foam or polystyrene foam corners are used.
Finishing the corners of PVC (plastic) panels is also quite simple. Only here you can use liquid nails, which are able to firmly fix any material on the surface.

The only thing to consider is that finishing the corners with PVC panels requires additional decoration, since plastic cuts will be visible on the surface of the corner. Use for such masking plastic corners small size. They stick to PVC panels using special glue or liquid nails. Watch the video on how you can shape the corners with decorative stone.

Curved corners are a common phenomenon that occurs not only in old apartments, but also in new buildings. If small wall irregularities can be masked with wallpaper or decorative elements, then corner defects after finishing with wallpaper or tiles will be even more noticeable. Alignment of external and internal corners can become part of the process of finishing the walls with finishing plaster and putty, or can be done separately if the condition of the wall surface does not require serious intervention. Let's find out how different methods.

Internal corners

The choice of one of the three alignment methods in this case depends on whether it is done together with the plastering of the walls or independently.

Lighthouse Alignment

This method is used only in the process of working with the entire surface of the walls.

Necessary materials

lighthouses - metal or wooden slats;
screws or dowels;
rule;
plumb;
spatulas - straight and angled.

Sequence of work

Fasten the beacons to the surface of the walls using fasteners at a distance equal to the length of the rule. Indentation from the corner - 5-7 cm.
Using a plumb line, determine deviations from the vertical, make marks on the floor and ceiling, and, if necessary, place wedges in the right places.
Start applying plaster on one side. Fill the space between the beacons, distribute the solution with the rule. After the layer dries, go to the second wall.

Important! Make sure that a large amount of the mixture does not collect at the junction. To eliminate excess after the composition has dried, use a spatula.

To form an even joint, use an angled spatula moistened with water.
After the plaster has dried, remove the beacons and seal the voids with the same composition.

Using the countershoulder

The best solution when aligning the corners is to use a counter-shoulder - a perforated corner made of aluminum.

Necessary materials

scissors for cutting metal;
long rule;
sandpaper;
putty mix.

Sequence of work

Measure the required length of the aluminum corner and carefully cut it with special scissors, being careful not to bend the malleable metal.
Apply a small amount gypsum plaster at the junction of the walls and attach the counter-shults, slightly pressing it with the rule. Remove excess mortar with a spatula, moving away from the joint with smoothing movements.
After the putty has dried, go over the surface with sandpaper. If there are small irregularities, apply another thin layer of putty.

Sickle Method

How to level the corner of the wall if it is not planned to carry out large-scale work on plastering and puttying the entire surface of the walls? In this situation, a wide sickle ribbon will help out.

Necessary materials

wooden rectangular bar 50-60 cm long;
plaster putty.

Sequence of work

Apply a small amount of mortar to the joint of the walls and to the surface adjacent to the corner. The width of the strip of applied putty will be 10 cm on each side.
Attach the reinforcing tape to the top of the corner and gently unwind the roll so that the sickle does not move to the side.
Pressing the bar to the joint, give the corner the correct shape. If the tape is wrinkled during the process, level it with a spatula, remove excess putty, moving in the direction from the joint.

Important! The movements of the spatula must be careful not to disturb the position of the tape. At the same time, you cannot wait for the mixture to dry, as this will deprive you of the opportunity to adjust the position of the sickle.

Alignment of external corners

For external corners, there are two ways to align: with and without a counter-shul.

Alignment method without countershoulder

To align the outer joint of the walls in this way, you will need:

spatulas;
rule;
ideally flat board or plank wrapped with tape;
fine-grained sandpaper.

Sequence of work

Knock down large protrusions, fill large gaps with plaster.
On the surface of the wall at the point of contact with the joint, place the bar. Do this in such a way that it protrudes from the corner by a distance equal to the thickness of the required plaster layer. Fasten it to the floor and ceiling, with the right length it can be inserted as a spacer.
Apply the mixture, spread with the rule of motion towards the joint with a slight downward slope. If necessary, repeat the procedure after the layer has dried.
After two or three days, remove the plank and attach it to the ledge on the other side, already plastered, and repeat the above steps.
After drying, sand the surface.

Forming an outer corner with a counter-shoulder

Using a profile will not only simplify the alignment process, but also reliably protect the outer corner from damage.

Necessary materials

gypsum mixture;
rule;
putty knife;
level;
sandpaper with fine grain.

Sequence of work

Apply the prepared mortar to the surfaces adjacent to the wall joint.
Fasten the countershoulder cut to the desired length at the joint, using the rule to prevent deformation of the aluminum corner.
Remove excess mixture with a spatula, check with a level that the corner is fastened correctly, if necessary, adjust its position.
After drying, sand the surface with fine sandpaper.
The final leveling is carried out together with the application of putty on the rest of the wall surface.

Aligning corners with plaster or putty is a more familiar method for many, but at the same time it is quite “dirty” and laborious. It is worth resorting to this method if the curvature is minimal. In the case of significant curvature of walls and corners, it would be more appropriate to use drywall sheets.

Repair in the apartment takes on a finished look only if everything is correctly and neatly decorated. structural elements. Manufacturers of finishing materials offer decorative elements for all types of coatings: plaster, plastic and MDF panels, wallpaper, wooden lining.

Why do we need decorative corners on the walls

An important role in the visual perception of the interior is played by the decoration of the corners of the walls in the apartment. They are the ones who lose their attractiveness the fastest. appearance. Moving around the apartment, people touch the corners with their shoulders, scratch with portable objects. Surfaces covered with wallpaper are quickly erased.

The protection of the corners of the walls is achieved by overlays of various materials.

In addition to the protective functions, the decor of the corners masks minor imperfections in the finish and inconsistencies in the materials used, such as ceramic tiles.

Important! For the design of walls finished with panels, a decorative corner is sure to be used.

Metal corners for walls will help protect the surface from damage by pets. Often, for some time, decorative finishing of the corners will help to return an attractive appearance to housing. Framing the photo wallpaper with a border tape will give the image the look of a painting.

When to apply

Corners are used in cases:

the need to improve the visual perception of the angle;
when there is a need to protect the wall decoration material from damage by children or pets;
organization of protection against pollution in case of accidental contact;
decorative design of the corner provided for by the project;
docking of surfaces when materials that require design are used in the interior (tiles, plastic and MDF panels);
placement near the corner of large-sized furniture, in this case, the vertical surfaces of the cabinet and walls will look harmonious.

Types of decorative corners on the walls

Understanding the importance of the problem, manufacturers produce products for all types of finishing work:

arched;
for ceramic tiles;
for outside and inside corners.

Note! Docking a decor from several elements cannot be called a beautiful solution. The standard length of decorative corners is 2700 and 3000 mm, it is enough to decorate one corner in the apartment. When buying, you need to purchase a separate decorative element for each corner.

Arched

The design of arched corners has some features. One side of such products is smaller than the other, thanks to which the product becomes flexible, which allows you to stick it without cutting one of the sides. You can’t do without such an element if the wall surface is made of plastic or MDF panels, drywall, lining.

Manufacturers produce corners of any color. When choosing, you should be guided by your taste and the general idea of \u200b\u200bfinishing the apartment.

In general, you should keep in mind the rule: to protect the corner, an element is used that is one tone darker than the wall surface itself. In this case, the lines will be clearer, emphasize the overall style of interior decoration. If wood-like materials are used in the room, for example, linoleum or board-like laminate, it is advisable to use corners made in the same style. Decorative stripes are glued to the wallpaper.

The width of the sides of the corner is selected, taking into account the dimensions of the arched structure and the parameters of the room: the height of the ceilings and the thickness of the wall in which the opening is made

Proportions must be observed: the larger the room, the higher the ceiling and the thicker the walls, the wider the side of the corner is chosen. A narrow decorative element will not emphasize interior details. Conversely, a wide corner looks unnatural in small kitchen or hallway.

On a note. In special literature and among builders, the side of the corner is called a shelf, this is provided for by GOST. The same name is given to the sides of beams and channels to which the load is applied.

Corners for ceramic tiles

When decorating rooms with tiles, places necessarily appear where its ends are visible:

door or window (if any) openings of the bathroom;
niches in the walls for cabinets or lighting lamps;
columns;
steps under the bath or shower;
work apron over the workplace in the kitchen;
countertops.

You can hide the ends of the tiles by painting them with paint, sticking a decorative overlay, or not touching them at all. Such decoration will not add beauty to the room.

Such elements are made of aluminum alloy or plastic. Coloring of plastic products occurs during manufacture. The paint is incorporated into the plastic. This allows you not to worry about the preservation of the shade throughout the entire period of operation.

Metal parts are polished and varnished. To obtain different colors, thermal or chemical methods of staining are used.

One side of the corner has a perforated ledge. It is mounted on the surface of a wall or ledge. When laying, the perforation is filled with adhesive for ceramic tiles, and after drying, the product is securely connected to the wall. The opposite side is made in the form of an internal protrusion. It includes tiles laid on the adjoining wall.

Attention! When buying a corner, take into account the thickness of the ceramic tile. The dimensions of the protrusions and recesses on the decor elements must match the thickness of the tile.

In addition to decorative properties, the corner helps to level the walls.

For the design of joints in three planes, special overlays are used.

To finish the inner corner, special-shaped profiles, steel or aluminum corners are used.

For outside and inside corners

For interior decoration, decorative corners are used on the corners of the walls. Surfaces covered with plaster, wallpaper, are finished with decorative elements in the form of overlays.

The design of the corner allows you to bend it in different directions. Due to this, such a finishing element is suitable for decorating external and internal corners (acute and blunt), the size of which can be any: from 90 to 170 degrees.

Important! Manufacturers for the entire line of MDF panels produce corners with a finish similar in color and texture. Taking into account the wide variety of shades, it is advisable to simultaneously purchase MDF panels and decorative elements for them.

Polyvinyl chloride corners are suitable for decorating right angles. They are available with walls of various sizes, which allows you to hide gaps of various widths.

A separate type of decorative corners can be considered additional elements for plastic panels, on sale they can be found under the name moldings. Moldings reliably hide from view the irregularities made when cutting the panels.

Elements are attached to the surface to be trimmed with screws or nails if the crate is wooden. This serves as an additional reinforcement of the structure. For any type of connection, you can choose the desired molding option. A significant drawback of such decorative elements can be considered the absence of products of various colors, mainly white colors are on sale.

textured corners

Solve the problem of white color corners for plastic panels help textured corners.

The three-dimensional structure of the surface allows you to choose the right option for plastic panels of any kind and color. Volumetric textured finishing elements made of cast polyurethane look much more profitable and, one might say, “richer” on the walls.

Wooden corners

The corners of the walls covered with lining, as a rule, are decorated with wooden elements.

Such finishing elements harmoniously look in the interior, they are not subject to deformation during temperature fluctuations. Fastening is carried out with special nails with a reduced (hidden) hat or with glue on liquid nails.

natural stone corners

Natural materials are gaining great popularity in the decoration of apartments. One of them is natural stone.

Advice. Natural stone, covering the entire surface of the wall, looks appropriate in spacious buildings. For decoration small areas the stone is used strictly dosed.

Fastening natural stone produced using building mixtures on a prepared surface.

artificial stone corners

A stone corner on the wall cannot be glued to the wallpaper. In these cases, the interior decoration is made with corners made of artificial material. Elements are made of expanded polystyrene (polystyrene), and they are covered with hard plastic. This makes them resistant to abrasion, scratches from accidental touches and impacts with various objects. Such elements look good when glued to light-colored wallpapers.

In cases where the walls are decorated with panels made under artificial stone, special corners are used.

There are starting elements to start finishing from anywhere on the surface.

Making aprons for the kitchen

Part of the kitchen wall adjacent to the sink hob, cutting table, definitely needs protection. Tiles, as a decorative finish, give way to glass, mirrors, decorative panels made of hardboard. It is difficult to make these surfaces solid, therefore, it becomes necessary to design corners, joints of adjoining different materials.

In such cases, various elements are successfully applied. For example, a decorative metal corner looks good when decorating glass or mirror mosaics. Appropriate in terms high humidity the corners are made of polished or painted aluminum. It is inappropriate to use MDF parts here - their service life will not last long.

Decorative wall corners are an important part of interior design. Properly selected elements will allow you to get unique solutions in the decoration of the apartment, extend the life of the parts until the next repair.

Video

Plastic corners for walls during installation are almost always used. After all, the alignment of the corners is one of the most difficult finishing works. Here you need to have knowledge and skills.

Usually, various corners are installed to protect the corners, it depends on the unevenness and on the interior design. It is also necessary to choose the right material for making the corner, because there are several of them. It is with this finishing material we will get to know each other today. Also on the video in this article and the photo you can see the options for the practical use of this material.

When Corner Alignment Is Needed

Plastic corners for walls are sometimes extremely necessary, and let's figure it out right away, you will need this finishing option:

In cases where you plan to put rectangular furniture in the corner. In the aligned walls, the furniture rises perfectly.
Also for protection against mechanical damage. If there is a large unevenness, then it is better not to level the surface. Because the space is greatly reduced. Such unevenness can be perfectly removed with an artificial stone, it fits into any design.
Also, if the vertical angle is not perpendicular to the axis of the earth, then a small deviation can be completely leveled using the corner.

Types of corners and corner materials

Corners for plastic walls are selected according to the type of corner.

There are two options here:

Inner corner corner

Internal corners generally do not fall into the risk zone, as they are difficult to access.

Although it is not particularly susceptible to mechanical stress, its evenness is sometimes extremely important.

outside corner corner

But the outer corners are always a headache, as they are easy to damage. They do not have high strength, the wallpaper can be torn off, the paint can be peeled off.

For example, moving large furniture or appliances, there is always a risk of damage. From this we can conclude that the corners require protection.

The corner can be made from several materials. This largely depends on its characteristics.

Let's see how long a PVC corner will suit you:

Production material	Characteristics
Plastic	Durable, resistant to moisture, easy to install and perfectly processed;
Metal	It has many positive qualities, but the cost is very high, it also has a lot of weight and is susceptible to corrosion;
MDF	Durable, comparable to natural wood. Exposure to moisture is not acceptable;
Wood	It looks beautiful, but is flammable, and a humid environment is also not recommended;
Stone	Durable, but installation is a laborious process, it also has a lot of weight and therefore is not always acceptable. It is also quite difficult to process;
Metal galvanized profile	Resistant to moisture. Doesn't weigh much. But there are processing difficulties.

Attention: The main thing is that the corners are light and durable. Then they are attached without problems and simply change during repairs.

Why choose plastic

The choice is better to stop on plastic decorative corners. They are the most commonly used. Today, the market offers a diverse set of plastic corners. This material has a diverse color palette, and also have a good property - softness.

There are two types of plastic corners - external and internal corners. Therefore, many manufacturers paint plastic not only outside, but also inside. They have many benefits.

Let's try to summarize, this is in a small list, noting the main ones:

They have a very small weight, which increases the level of service;
The color scheme is diverse - from white to black;
Can be given any shape;
Easy to cut;
Well glued;
Hide irregularities or imperfections;
Give completeness to straight lines;
Shelf life over 100 years;
Pretty low price;
The possibility of do-it-yourself installation also attracts the consumer.

Attention: All the corners come in the sale of the same length, which helps to accurately calculate the required quantity and choose the right shade for you. But they have a different shelf, so you need to pay attention to this.

The corners are installed at the end, after all installation and repair work has been completed. The corners are glued to the wall using mounting adhesive for plastic. If you are producing this species work for the first time, it is necessary to use the corners of medium width, and the height of the plastic corners is standard 2.5 m.

Areas of application of plastic corners

Plastic corners will become real helpers in any interior. They emphasize all the lines that you want to highlight in the decor. They also help to hide any irregularities or problems in the plastered walls.

Consider situations where you really can’t do without their help:

During installation window slopes inside;
When installing windows from the outside, to hide traces of foam, to give an aesthetic appearance;
Framing door slopes;
For the design of arched openings (see How to finish an arch: forms of arches and types of finishes);
The corners of the walls pasted over with wallpaper;
At corners that are made of drywall, for putty;
When creating corners, when working with facing tiles;
When using plastic panels indoors;
Formation of joints when working with siding (see Everything about siding lining or sketches about the well-known).

You can list for a long time for which cases a decorative plastic corner is useful.

However, even from this list, the evidence of its wide application is visible:

The corner is produced by heating PVC, it is given the required shape. Such a corner is smooth and without cracks.
Note that the corners are not standard. Width may vary. One side is wider than the other. Such plastic decorative corners are suitable for arched openings.
Manufacturers produce a large number of plain plastic corners. They also depict an imitation under natural material, for example, under a stone or a tree. You can find the corner that fits perfectly into color scheme premises.

Types of corners by type of finish

You can determine which corner is needed, internal or external for work, after you select the type of finish.

The outer corner is in the size of 90 or 105 degrees. Plastic window edging, with the help of plastic corners at 90 degrees, if not enough, put a second shelf.
If two shelves remain visible, then they are framed with plastic corners of 105 degrees.
In interior work, a corner is used that can hide the joining of materials and irregularities.
Corners put the final point in the repair - finishing works, give a finished look to the room, after repair. The main thing is to choose the right corners for your interior.

Installation of corners

Glue is the most necessary thing for installing corners. Since the reliability of fastening depends on it. On the market today, a lot of all kinds of glue are sold, each differs in composition and properties.

How to choose best glue? If you choose it incorrectly, you can spoil the external aesthetic appearance.

Let's look at what types exist and what they are suitable for:

Fixing a plastic corner to polyurethane

It has a number of positive aspects - it does not leave marks, it is elastic, it has high strength. It is most suitable for gluing a corner with plastic panels. But there are also disadvantages, it has a pungent odor and long gluing, about two days. You need to apply such glue over the entire surface of the corner, do not immediately glue it. It takes about 30 minutes for the glue to harden a little.

Attaching a plastic corner to liquid nails

The most popular adhesive It gained its fame due to its high strength. It is also called mounting adhesive. It contains sodium carbonate, which allows you to fill the voids between the corner and the wall.

It is perfect for gluing plastic corners with any type of wallpaper. If you use white corners during installation, then it is better to buy transparent liquid nails; with other shades of wallpaper, you can use any glue composition.

Note that liquid nails do not spoil plastic corners and wallpaper. Apply glue to the plastic corner with a snake.

We fix the PVC corner on the sealant

It's a hard glue. The choice must be approached with all responsibility. Sealant is needed to bond plastic to tiles.

Note that not every sealant can be suitable for bonding plastic.

Experts say that it is better to use acrylic sealant.

It is durable for bonding plastic, has no color and odor. And it has high moisture resistance.

Attention: When deciding how to glue the plastic corner to the wall, it is worth looking at what you will attach the corner to. Then unforeseen circumstances will not arise and the installation will be successful. Apply glue to the corner dotted.

Preparatory work

When we work with right angles, we should not have any special problems. The plastic corner is easily cut with a construction knife or a hacksaw.

But with arched work, not everything is so simple. Here we need to bend a straight plastic corner. How to do it?

From the above, we can recall that at high temperatures the plastic corner easily changes shape. To do this, we need a building hair dryer, we heat the corner, give the desired shape, fix it. Work continues after the plastic has cooled.
Often in the store the corners are in the dust, so before work, you need to clean them, degrease, wipe dry. Not a drop of moisture should remain on the plastic, if they do get in, the glue will not fix well, and over time it may fall off.

Attention: For the arch, a corner with notches is selected. If you took a straight line, then you need to make cuts along the contour with a hacksaw.

Technology for gluing plastic corners

Each type of material has its own system for gluing plastic corners. We will analyze all cases in detail.

So that you already know exactly what you need to do:

To glue a plastic corner to the wallpaper, you first need to pick it up. It is better to choose a corner to match the wallpaper, it looks aesthetically beautiful. Measure the height you need.
After you need to cut. Here comes the most a big problem for non-professionals. The plastic corner is cut off at an angle of 45 degrees. Experts do it by sight. But since you are not a professional in this matter, you need to take a miter box and metal shears.

Attention: A hacksaw should be taken for metal or with a fine tooth. Otherwise, the material will bite and you will get an uneven cut.

After cutting off the desired length, prepare the plastic corner itself. Wipe off dust, check for water, if present, wipe dry.
Now you need to prepare the wallpaper, remove the wallpaper at the junction of the corners. In this case, you need to use liquid nails. However, if you have a light wallpaper, then choose a light glue, and if you have a dark shade, then any color of glue will suit you.
Apply glue to the plastic and wallpaper evenly, but do not overdo it, since it is unrealistic to remove such glue from the wallpaper.

Glue the plastic corner to the walls in the same way as in the previous case:

Clean the wall, prepare the corner, wipe off dirt, check for moisture. We use a different glue, it is required for painted walls, acrylic sealant. Apply gently to the inside of the corner and attach to the wall. Exactly the same process is performed when gluing a plastic corner to the slopes.
The most difficult type of work is the fastening of a plastic corner to an arched opening. The type of glue you choose based on what type of material is laid out on the wall. Next, bend the plastic corner, as we described above.
Now let's move on to the hardest part - cutting the plastic. On the side that goes to the inner opening, cut end-to-end. And on the outside, we leave a margin. Then there will be an opportunity to trim. The method of gluing itself depends on the materials.

Now you have basic knowledge installation of plastic corners. You can safely move on to practice. As you can see, the installation process is not so complicated, but how invaluable. And note that their cost is not high. Even people with a limited budget for repairs can afford to buy them.

The corners will perfectly preserve the originality of the room. Since they will protect the most vulnerable places in the interior. And the room will delight you for more than one year.

Plastic corners to protect wall corners will help you maintain the geometry of the corner even under mechanical stress. And the instructions will help to do the job quickly and efficiently.

Finishing the corners in the apartment should be resorted to in cases where small children grow up in the family or animals are kept. Since stucco finishing mixtures do not have great strength, they are destroyed by light impact on them.

Especially often external corners are destroyed. Dents often appear on the corners pasted over with wallpaper, notches appear on the painted corners.

To protect the corners, the use of special devices and techniques that protect the corners from destruction is required.
