Decor for corners in the apartment. Plastic corners for protecting wall corners: installation options and rules

Immediately it is worth explaining that the corners are external and internal. The first, as it is not difficult to understand, are mounted on top of the finish, and the second under it. This means that the functionality of the elements is slightly different. Both types serve to protect the outer corners from impact, while the outer ones additionally carry an aesthetic message. There are also corners and internal ones that protect not from impacts, but from deformation changes in the base of the walls, while keeping the exterior finish intact. Let's take a closer look at each type of corners.

Table 1. Varieties of plastic corners.

Corners, photo	Description
	The perforated corner belongs to the category of internal - it remains in the layers of plaster or putty, which means it is invisible to the eye. Perforation is needed on it so that the gypsum mixture passes through the holes, thereby fixing the element more firmly. Theoretically, such corners can be used for internal and external corners, but in practice only for external ones. The fact is that they have an uneven geometry (the angle is somewhat sharp) and at the same time it is normal to spring like that when you try to unbend them a little. And if, when mounted on an outer corner, it can be additionally fixed in the desired position with a masking tape, then such a number will not work here. This corner helps to make the corners more even. In the event of an impact, the outer layer of putty can fly off from them - all this is quite simple to restore.
	This version of the perforated corner will cost you a little more, but it has an additional layer of fiberglass that will protect the corner even better. When buying, also look at the quality of workmanship if you need to reinforce the inner corner in the room. The undeniable advantage of plastic plaster corners is that they are not subject to corrosion. They can be safely used in wet areas, while their metal competitors will not tolerate the harmful effects of steam.
	Another type of corner is intended for framing and precise puttying of plasterboard arches, etc. Since the arches have no internal corners, the purpose of such an element is the only one. They can be used when puttying plasterboard ceilings that have curved sections. Advice! You can make such a corner yourself by cutting one side of a regular perforated corner in some increments.
	L-shaped corners are mounted on top of the trim. They come in different sizes, shapes and colors. Most often there are white corners, but you can also buy textured ones that imitate a wood pattern. To be honest, we have never seen other pure colors in stores. Such a corner allows not only to protect the corner, but also to make it visually more even and attractive. He will not allow, say, wallpaper to peel off in this difficult place, so the edging of a door or window opening will always look attractive.
	This corner is very thick. It is not made of plastic (PVC), but polyurethane. Both are polymers, so we didn't break them down into separate classes. The purpose of such a corner is exactly the same as that of the previous one, however, they are completely inelastic, so they need well-prepared corners.
	Another type of outdoor decorative corner. It differs from the previous options in that it can bend, as shown in the diagram on the left. This property makes it more convenient to use, especially if you need to mount the corner on an uneven corner. It can be used for both external and internal corners. The solution also has a drawback - there is a thin film at the junction of the blades, which can easily be torn upon impact.
	This version of the corner is designed to be used in conjunction with ceramic tiles. Its shape is such that the mounting tail must be immersed in the adhesive connecting the tile and the wall during installation. Such an insert is very useful - it will protect the finish from chipping, and more importantly, in the event of a head hit on it, which may well happen in the bathroom if a person slips, the falling one will be limited to a bump, and not a heavy cut. Such a measure can save someone's life.
	These corners are used by good tilers only at the request of the client. The fact is that their installation is problematic, and the corners rarely turn out beautiful. Often the surface of the tile is deformed, which is allowed by the standards in its manufacture, in another situation it may simply be an uneven wall. All this leads to the fact that it is impossible to press the corner against the wall, and there are large gaps that you cannot normally cover even with grout.
	Such corners are mechanically attached to the frame, which is sheathed with plastic. They are both decorative and load-bearing structural element. Carefully cover the cut edges of the plastic panels. They are quite difficult to install, and the last corner is completely made from the start, since it is impossible to install the inner one.
	A corner similar in design, only for external corners.

There are some other models of corners, but they are very specific, so when decorating walls, they will not be needed.

Installation of plastic corners

So, in fact, we have three types of corner, which are mounted on different materials and for different purposes. Let's take a closer look at how to install each.

Hidden corners for putty

For work, we need the following set of materials and tools:

Perforated corner.
Putty or gypsum plaster, depending on at what stage you perform the installation.
Container for mixing the mixture.
A pair of spatulas.
Something for cutting corners, such as metal shears.
You can also use a construction stapler to pre-fix the part.

Step 1 - applying putty to the corner. Cut off the corner along the length and knead the putty in a bucket. Next, we collect it with a spatula and apply it directly to the corner so that it hits both adjacent walls. We pass in this manner the entire area on which the corner will be glued.

Step 2 - install the corner. We put the corner in place and press it into the putty. Press down better so that a minimal layer remains under the plastic.

Interesting to know! Plastic corners often have a bulge in the middle, which is why you need to build up a layer of putty in order to smoothly approach the corner. To prevent this from happening, the walls can be sanded, which will allow you to drown the part inward. You can’t do this on drywall, so we go as we go.

Step 3 - press the corner. The corner must be pressed from both sides at once. Use a spatula for this - this will allow you to align as accurately as possible in a plane with the walls.

Step 4 - level the putty. Then we draw a spatula along the corner and remove all the protruding putty, simultaneously leveling it and filling the voids. Make the edges as smooth as possible, but do not try to create a perfectly smooth surface - this is now useless. At this stage, you can check the evenness of the position of the corner according to the level and make adjustments if necessary.

Step 5 - stretching the corner. We give the starting layer of putty to dry, after which we proceed to leveling the corner. We need a small rule that will help smooth out the difference as much as possible, due to the protruding corner. We apply putty on the walls and stretch it, getting an even and beautiful angle. In principle, that's all, but if you wish, you can once again smear everything under zero with a spatula after this layer has hardened.

Due to the rigidity of the corner, we managed to achieve the correct geometry of the outer corner of the window slope, it is also possible to do this only with a trowel, but some experience is required, and such a corner will not be strong.

If you are not a supporter of whitewashed gypsum walls, but at the same time want to be able to change the look and mood of the rooms more often and at no extra cost, then why not look towards wallpapers that can be painted over and over again? In we will tell you how to paint wallpaper for painting correctly, strictly according to technology, so that they serve for a long time.

Installing external corners with glue

Do you think that it will be easier to stick plastic corners on glue than to wall up perforated ones into putty? You are deeply mistaken, since this work requires high accuracy in measuring and cutting material. Now you will see for yourself.

To work, we need the following:

Masking adhesive tape for pre-fixing parts.
Glue liquid nails and a gun under it.
A stationery knife with thick blades or metal scissors for cutting a corner.
Tape measure and pencil for measurements.
White silicone sealant to mask possible gaps.
Square for adjusting an angle of 45 degrees.

In the example, we will consider how the window slope is framed.

Step 1 - prepare the workplace. In order not to spoil the window sill (soil and scratch), it must first be covered with something. We have laminate flooring. We put all the necessary tools on top so that it is always at hand.

Step 2 - measuring the sides of the slope. With a tape measure, we measure the height of any of the sides of the slope. It is important to focus on the distance from the window sill to the edge of the horizontal side of the slope. Errors are not allowed, so measure everything to the nearest millimeter - use a good tool, not a rusty old one, on which you can’t make out the graduations.

Step 3 - marking the corner. We transfer the resulting dimensions to the corner and put a mark with a pencil. Make sure that the corner does not bend, otherwise you will get large errors. It is best to lay it on a flat surface and take all measurements in this position.

Step 4 - Marking at 45 degrees. We take the square and set it as shown in the photo, orienting exactly on the mark made earlier. We draw an oblique line along which we will cut the part.

Advice! It is also better to make the first mark in the corner, setting exactly 90 degrees, so as not to make a mistake when cutting.

Step 5 - cutting the corner. We cut our corner exactly along the drawn lines. There shouldn't be any questions here. The only thing is, if you use metal scissors, you can carefully trim the edges.

Step 6 - Apply glue to the back of the corner. We load a tube with glue into the gun and squeeze it onto the inside of the corner. We advise you to double-check the item beforehand, you may have made a mistake in the measurements. Glue can be applied in a continuous strip or do it pointwise.

Step 7 - gluing the corner. Then we apply the corner to the installation site and press it along the entire length. If you have glue sticking out of the edges, then immediately wipe it off with a damp cloth.

Attention! Do not use synthetic resin based compound. It can be washed off only with a solvent. You will definitely stain the wallpaper and putty with untidy yellow spots. Buy acrylic glue, you can also use silicone, but it will also be difficult to remove.

In exactly the same manner, we put the second vertical side.

Step 8 - preparing the corner up. It will take longer to tinker with the upper part of the slope. We need to accurately measure the distance from corner to corner, then transfer it to the workpiece and put marks. At the same time, we measure not from the edge of the part, but with an indent wider than the thickness of the corner. Next, ears are cut out on the corner, as shown in the photo. We do not mark the oblique cut, since we will do it after the fact.

Step 9 - simultaneous marking and cutting. We take our workpiece and set it on a slope, slipping the ears under the oblique sections of the vertical elements. Then a clerical knife with a sharp blade is taken - with it we carefully first outline the line, and then we go deep into the incision with repeated passes until we completely cut off the excess part.

As a result, we get a very even joint. If, nevertheless, the gap remains, then it can be easily covered with white silicone sealant. Next, the upper corner is removed, glue is applied to it, after which it is finally mounted.

Installation of corners for ceramic tiles

We already wrote that the use of such corners not only decorates the finish, but also makes the outer corners in the room less traumatic. For this reason, we advise you to always use them, especially since it is much more difficult to make corners from tiles with a 45-degree cut. In our work, we must take into account the following points

Step 1 - choose the right size corner. Wall tiles from different collections can be from 5 to 12 mm in thickness. Therefore, it is necessary to choose the right size of the corner. To do this, be guided by the numbers, choosing so that the corner is 1 mm larger, since you also need to take into account the thickness of the tile adhesive layer. Or take one tile and slide it into the cavity of the corner - it should fit into it and go inside a little.

Interesting to know! If the tile does not go inside the corner, you will not be able to hide the irregularities of its edges.

Step 2 - tiling one side of the corner. The corner has only one mounting flange, so it will only be held by tiles on one side of the corner. On the other side, it has a small protrusion, which should hide the edge of the tiled surface on the adjacent wall. From this we deduce the following procedure. First, one side of the corner is tiled, and it is desirable to leave the factory, not cut off side on the corner.

In this case, it is necessary that the resulting face be set strictly along the vertical level. Also, it should not protrude much beyond the corner (only 1 mm, it is better to check this by applying the corner on a dry one) or, conversely, not reach it.

The plane of the wall itself must also be level and not have differences throughout, otherwise gaps will appear between the finish and the decorative element.

Step 3 - prepare the corner. Then we take a tape measure and measure the exact distance, in the manner we did in the previous instructions. The corner also needs to be cut at a 45 degree angle, but this is difficult to do due to the rounded shape of the element. In work, we need a miter box in which we need to lay a corner, and, guided by the mark, cut the part with a hacksaw.

Advice! Immediately shorten the mounting part of the part by half a centimeter, as it may later interfere with docking with the horizontal corner.

Step 4 - fixing the corner. We install the corners in their place. In the example in the photo, the master is laying tiles on a gypsum fiber wall, so he fixed the frame with self-tapping screws with a press washer. This solution is temporary - the screws will be unscrewed as the corner is tiled. Alternatively, you could use a stapler with staples, then you don’t have to remove anything.

If your wall is concrete, then you can strengthen the corner with a thin layer of tile adhesive, which is applied before installing the element. You can do without temporary fixing, but then there is no guarantee that you can definitely combine the parts. Please note that the master with the photo did it perfectly.

Step 5 - cutting the tile and trying it on. According to the planned layout, we cut the tile, which will be installed on the second side of the corner. We apply it for a preliminary measurement and see that it cannot enter the corner. The fact is that all wall ceramic tiles have some narrowing at the edges. Some models do have a deliberately convex shape, and the difference can be up to 3-4 mm. How to act in this situation?

Step 6 - marking the back surface of the tile. Firstly, you can initially attend to buying a wider corner, but again, without cutting the tile, you won’t be able to measure it on the spot. Secondly, we can slightly reduce the thickness of the tile where it overlaps the corner mounting strip. To do this, first make a mark with a pencil on the back of the tile, then take a bar with sandpaper and clean off 1-2 mm of material. Of course, such work takes much more time from the master, but if you could not accurately select the size of the corner in advance, there will be no other way out.

Step 7 - fixing the corner. We proceed to the installation of tiles and the simultaneous fastening of the corner. We take the diluted tile adhesive and with a spatula gently press it into the perforation of the mounting plate. Do not make layers and immediately remove all unnecessary, as this glue will interfere with the normal sinking of the tile into the corner.

Step 8 - Applying glue to the wall. We spread glue on the wall using a comb bevel. You can also apply it and not a tile, but then you will need to remove the excess from the edge that we turned before installation.

Step 9 - gluing tiles. We glue the tiles. To begin with, we feed it a little forward with a turned edge so that it enters the corner. Then we press the second side and gently tap it on the surface. We align the plane with the rest of the already installed tiles and continue to move on, simultaneously unscrewing the screws so that they do not interfere with work.

Step 10 - additional fixation of the corner. When the tile adhesive dries, the corner will merge into it, and it will be impossible to remove it just like that, but while the composition is still liquid, the decorative element can be accidentally displaced, which will disrupt the structure of the adhesive. To prevent this from happening, we additionally fix the corner with pieces of masking tape.

Conclusion

So, we have dismantled the installation of three types of corners. We didn’t write about the options on the PVC panel, since everything is already very clear there - we fix the part in level on the brackets, insert the panels into it. The material turned out to be quite informative and voluminous. We hope you found the information you are interested in.

Flat corners - sign of a quality repair. However, this result is considered to be the exception rather than the rule.

Often, uneven corners can greatly spoil the impression of the repair work done, since as a result of this drawback, significant visual distortions of the finishing finishing material are possible.

Aligning wall corners is important final element of wall finishing works. How to align the corner of the wall with your own hands, we understand in this article.

Joints are a rather difficult area to process: to make perfect 90-degree corner surfaces, you will have to put a lot of effort and care.

Do-it-yourself wall alignment - myth or reality?

It is generally accepted that do-it-yourself wall decoration is much easier than ceiling correction, but this statement is only partially true. Often the reason why angular irregularities can occur is poor quality plastering.

If certain deviations of the corner surfaces are found, they should be eliminated before finishing the walls.

This is especially true when it is planned to stick wallpaper with a pattern in the room or install ceramic tiles - with such finishes corner surface defects will be obvious.

Depending on the type of finish, a method is selected - it can be done either with the help of GKL or with the help of dry mixes. Irregularities in corner spaces are corrected using the method of alignment by ledges or by level.

First option most preferable in the case when it is planned to paint the walls or finish with a decorative layer of plaster. Second option acceptable when subsequent wallpapering is expected.

Aligning corner spaces on your own may seem like a very troublesome and almost impossible task, but this is not so.

Subject to certain rules and the availability of the necessary tools, correction of wall joints will be possible even for a beginner.

Corner surfaces can be leveled using plaster or putty, drywall sheets and a perforated corner with a mesh.

Wherein alignment with GKL is not recommended in the event that the finishing will be laying ceramic tiles or porcelain stoneware: a surface that is too smooth will not ensure strong adhesion of the finishing material to the base.

Ideal angle: how to measure skew and achieve 90º?

Sometimes it pays to think- Is it so important to bring wall joints to perfection? To answer this question, you need to understand how important it is in this case to clearly set the corner joints at 90º.

In some cases, when only a cosmetic update of the interior space is planned and no additional costs are expected, the alignment of wall joints can be omitted.

In other cases, setting 90º is essential part of the renovation, since some modern furniture and appliances require only such a base.

Once the alignment decision has been made, the angular misalignment must be carefully measured.

To determine the vertical skew, it is enough to attach a ruler or rule vertically to the corner.

Next to the ruler is to lean the spirit level, which will help to visually determine the value of the distortion along the wall. After the work done, it is necessary to measure with a ruler the maximum skew from the vertical of the corner or wall - as a result, the desired value will be obtained.

In the same way, one can measure deviation from an equal angle in the horizontal plane, however, in this case, a longer ruler or profile is needed: horizontal distortions, as a rule, are of less importance, so a greater distance will be needed to measure them.

In the case when it is impossible to visually determine the skew, you will need a profile with a length of at least two meters.

Varieties of materials for work

The most common and effective alignment methods are varieties in which dry mixes and drywall sheets are used. Quite effectively, the method of eliminating defects with the help of a perforated corner has also proven itself.

To find out which method will be effective in each case, you need to consider each of them in detail.

With putty or plaster

In order for the corner correction to be successful, you need to work use high quality blends made by trusted manufacturers.

Perhaps the price tag for these mixtures will be slightly higher than unknown brands, but there will be no doubt about the quality of the work done.

The most convenient way to work involves gypsum plaster or starting. This option will allow you to make a correction using the thinnest layers and at the same time without subsidence.

To perform this type of work, you will need the following tools:

Roller or brush for priming the base;
Spirit level of any type, as well as a plumb line;
The container in which the plaster will be mixed;
Drill mixer;
Rule;
Wide and narrow spatula;
Primer for the base;
Dry mix for leveling.

Before starting work, you must to carry out priming of wall joints with a solution of deep penetration. Next, you need to calculate the required amount of plaster mixture.

Alignment by level must be done in the case when the surface will be finished with tiles of any kind. In the case of painting or gluing, alignment along the plane is sufficient.

The choice of mixture depends on outside or inside finishing work will be carried out. If you plan to finish corners located outdoors or in rooms with high humidity, you should choose a mixture based on cement, lime mixtures and polymers.

In the case when it is necessary to correct internal joints, plasters based on a gypsum mixture can be used.

Work procedure consists of the following steps:

In the case when the walls are erected evenly, the angle after alignment turns out by itself. For more convenient work you can use a counter- a special metal corner with perforation.

The plastering method is used when the angle misalignment is insignificant and does not exceed a few centimeters.

If the distortion turned out to be impressive, it is better to use drywall sheets.

Video instruction on how to properly putty corners:

Gypsum board as a means of achieving an even joint

Gypsum boards for leveling corners are a very effective tool. They apply when when leveling with plaster cannot give a quality result and have many advantages over plastering:

GKL do not require the removal of old wall coverings;
Do not require kneading dry mixes and the whole process proceeds without dirt;
Drywall plastering can be carried out immediately after installation.

Among the disadvantages of this type of finish, one can single out the relative brittleness of the material and its instability to serious mechanical damage. In addition, GKL is not used in rooms with a constantly high level of humidity.

If the walls of the room were originally lined with gypsum plasterboard, no adjustment of the corners is required. In the case when it became necessary to equalize the walls with drywall, it is necessary:

Carry out the installation of guides that will serve as the basis for drywall sheets;
Sew up the GKL frame with self-tapping screws or screws;
Apply reinforcing tape to reinforce internal corners;
Align perforated aluminum corners for outside corners;
Putty the joints.

A heavily littered wall requires the use of a combined method, which includes both plasterboard finishing and leveling with a plaster layer.

Perforated corner with mesh for perfect 90º

The leveling corner is used where it is necessary to strengthen the outer and outer corners. In addition, this material greatly facilitates the work of exhibiting perfect corner joints. In any case, the corner in which the perforated corner with the mesh is mounted will turn out to be perfectly even.

In order to expose such a corner, you need:

To make the transition to the corner from the wall invisible, you should plaster it with an overlap with the wall and smooth with a wide spatula.

Internal corners: features

For interior corners in the apartment, you can use both dry mixes and sheets. Before plastering, it is necessary to check the evenness of the corner joints using a plumb line and level.

If there are protruding bumps on the surfaces, they can be removed with a hammer or chisel.

After preparing the surface, it is primed with a special deep penetration compound. This method will make the corners stronger and improve the adhesion of the new plaster layer. The primer must be made along the entire length of the rule.

Even corners when plastering will provide special beacons. They need to be placed right in the corner space.

Lighthouse - a strip of gypsum solution about 5 centimeters wide. The mixture for beacons should not contain lumps.

The solution for the beacon is applied in a strip on one side of the corner joint, after which it is leveled using the rule.

After the first beacon dries, you can install the next one on the opposite side of the corner. Subsequently, it is necessary to align the angle completely with a special angled spatula.

The outer corner of the walls - how to achieve an even joint?

For external leveling work drywall is not used. For external corners, only dry building mixes are suitable.

First you need to check the outer corners for evenness. All protruding irregularities must be removed with a hammer.
The next step is the priming of the walls with the help of special deep impregnation compounds.
For reinforcing external corner joints perforated metal corners must be used, which will strengthen the joint and help avoid damage. They are pressed into the gypsum mortar and subsequently leveled with putty.
Excess mixture must be removed with a spatula. Then you need to make sure the exact vertical installation of the metal profile.
With the help of gypsum beacons on both sides, the angle is leveled and puttied.

Different ways to align outer corners are discussed in the video below:

Conclusion

Aligning corners with your own hands is a painstaking task, but it is not difficult. For high-quality work, it is better to use proven finishing materials. When performing work, patience, accuracy and care must be exercised.

The outer corners of the walls are the most vulnerable to damage, especially if there are small children or animals. After all, plaster mixtures are not durable and it is enough to slightly touch the corner with a small object to damage it. As a result, if the corner is covered with wallpaper, then dents form, and if it is painted with paint, then notches. Therefore, when repairing an apartment, it is necessary to strengthen the outer corners with special corners.

Corners are plastic PVC (in the photo on the left) and metal. Metal corners are installed during the repair of walls before they are leveled and puttyed, and after the repair is completed, they are not visible from the outside. Plastic corners are installed after pasting the walls with wallpaper or painting. Plastic comes in different colors and you can choose a corner to match the color of the wallpaper or wall color. Plastic corners can be installed at any time, for example, if the outer corner has lost its appearance due to damage or dirt.

With metal corner profile

Protection of external corners with a metal corner profile is preferable, since after the repair of the room, the corner profile is not visible and, most importantly, the problem of aligning the corners and the walls extending from the corner is solved.

The length of a standard corner profile is three meters, so before installing it, you need to measure the length of the corner with a tape measure and cut off the excess part of the profile.

Since the corner profile is made of thin steel, it is well cut with scissors for metal. The sides of the corner are cut towards each other, and the uncut part is easily broken by several folds.

If the corners of the walls are straight (if the walls are lined with gypsum boards), then it is easiest to fix the profile corner with small nails, as shown in the photo. If it is not possible to hammer carnations into the corner or it is uneven, then you need to apply a small amount of gypsum, alabaster or rotband on it at a distance of no more than 50 cm from each other, and until the solution has hardened, attach the profile corner to the leveled corner.

In order to securely fix the profile corner on the wall, if there is a gap between its sides and the wall, it is necessary to fill these gaps with a leveling mixture with a spatula before leveling or puttying the walls.

Such a measure will prevent the bending of the corner when leveling the walls and ensure that the corner is securely fastened as a beacon.

After the solution fixing the profile corner hardens, you can proceed to further finishing the adjacent walls. In the photo you see how the corner is hidden by a rotband in the wall surface extending from it.

The use of a profile corner will not only reliably protect the corners from destruction, but also make almost perfectly even outer corners. All six outer corners in the hallway during its repair, I protected and leveled with the help of a corner profile.

With plastic corners

PVC plastic corners are used to protect or decorate painted, wallpapered or decoratively coated exterior walls. But their use is not limited to this. With success, PVC corners can be used for decorative finishing of window and door slopes, panel joints, and in many other cases. Corners are produced in different colors and even transparent. There are widths from 10 mm to 100 mm, lengths of 1.5, 2.3 and 3.0 meters. There are also corners in the form of an arc, specially designed for installation at corners in arches.

Plastic corners are usually fixed with liquid nails, but there are corners with an adhesive layer applied on the inside, protected by anti-adhesion paper.

It should be noted that plastic corners can only be glued to sufficiently even corners, otherwise the gaps formed between the side of the corner and the wall can only worsen the appearance. Therefore, before deciding to protect the corner with a plastic corner, you need to determine if there will be cracks. To do this, attach a long construction ruler or a flat board to the corner. The PVC corner is quite elastic, and if the non-linearity of the wall corner is smooth, then a gap will not appear.

I used a PVC plastic corner for decorative design and protection against destruction of the corners formed by the wall and the slopes of the front door. The corner was chosen with a width of 10 mm in white, since the slopes were painted with white water-based paint, and the walls were the color of coffee with milk. What came out of it can be seen in the photo.

Since the angle formed by the slope of the doors and the wall was not straight, it was difficult to use a ruler to mark the PVC corner. Therefore, the marking was done by applying a corner to the place of the future installation and marking the cut points with a marker.

The thickness of the plastic corner is only 1 mm, therefore, by pressing it against the corner of the repair table, it is easy to cut the corner with a jigsaw. A metal hacksaw will work too. In order for the butt to turn out smooth, after sawing it, you need to walk along it with fine-grained sandpaper fixed on a wooden block.

To fix the corner, it is best to use liquid nails. When buying liquid nails, you need to make sure that they are intended, including for gluing PVC materials. If liquid nails are of high quality, then it is almost impossible to tear them off the corner after drying. I used liquid nails, the packaging of which you see in the photo.

For reliable fixing, it is enough to apply small portions of liquid nails at a distance of 15-20 cm along the entire length of the corner, as in the photo. Next, the corner is applied to the planned place, pressed and held for the time specified in the instructions for a specific brand of liquid nails. Usually the tacking time is a few minutes, and it will take a day to dry completely.

Next, a horizontal corner is marked, cut to size and applied for fitting. If a wedge-shaped gap has turned out between the corners, then with the help of sandpaper fixed on a wooden block, the end face is trimmed to the required size. It is better to make the horizontal corner a millimeter longer than it turned out when trying on. In this case, if you make a mistake, then there will be a possibility of adjustment.

Adjusting the vertical corners of the door slopes is easier, since their lower end is always covered with a floor plinth. Therefore, there is always the possibility for precise adjustment of the contacting ends of the corners.

If high strength is not required, then the outer corners of the walls can be protected with decorative MDF corners covered with a decorative plastic film. With the help of similar material, doors and the facade of the kitchen are now being made. The corners are easy to machine and allow the protection of external corners from 90° to 180°. The range of corners made of MDF is represented by a large selection of colors and patterns, which allows you to match them to the color of the wallpaper or wall color scheme. Protected by such a corner, the outer corners have a beautiful appearance. You can fix them at the corners with any liquid nails. I used this kind of corners for decorative framing of a large mirror mounted directly on the wall.

Many designers prefer not to leave the corners in the apartment raw and add unusual solutions to the interior for this part of the apartment. For others, the decoration can serve as protection if there are animals or small children in the house. Fragile corner wall upholstery requires attention and additional protection. Therefore, this article addresses the question of how to arrange the corners of the walls in the apartment, there are also photo examples.

One of the most problematic areas in interior decoration are the outer corners.

In what cases is it necessary to finish the corners in the apartment?

There can be many reasons for using such a building material. At the same time, each one has a different result of work. But most often this is due to the need to align the corners in the apartment. Unfortunately, builders often encounter such an oversight and have to carry out an additional stage of repair to make the room visually complete.

Decorative corners help to solve these problems.

To make the correct geometric shape, it is necessary to prepare the work surface. For this, the previous coating is removed: wallpaper, whitewash, plaster. Next, the builders carry out the treatment in the form of spraying with an antiseptic and cover with a new layer of primer.

The inner corners are more or less protected by wallpaper, which allows you to hide the bumps. But the outer corners are always in sight and it is not easy to hide damage here. This requires the use of a special decorative coating.

To strengthen the inner corners of the walls, plastering of the corner itself and the wall adjacent to it is often used, and drywall is also used to correct and finish the corners.

You can protect the corners in the apartment in different ways and materials. When applying plaster, it should be borne in mind that this method is quite laborious and time-consuming.

With a slight curvature of the corner itself, a frameless method of fixing drywall is used, but if the curvature is more than 2 cm, it is worth using a frame made of a metal profile or wooden bars. This method allows you to achieve almost perfectly even walls and ceilings, but at the same time the size of the room itself is significantly reduced.
