How to align interior corners. Three simple ways to align the corners of the walls. Aligning the inner corner

An integral part of the repair in the house is the alignment of the outer and inner corners of the walls. If this work is neglected, then the interior of any room will deteriorate. How to align the corner of the wall and will be discussed in our article.

There are several ways to bring the corners of the walls to normal. You can align them with:

• plaster mixture;
• metal profile;
• drywall.

plaster mixture

This technique is used for slight bulges and small recesses of the corner, when the differences in adjacent planes are up to 1 cm. The wall corners are aligned using a long rule.

The technology of using a plaster mixture involves the following works:

• to determine the most protruding places, the rule is vertically leaning in the corner against one of the walls;
• if possible, all protruding areas are ground;
• as beacons ( extreme points) will serve as protrusions that cannot be removed;
• extreme points are indicated by a marker;
• plumb and level determine the lower and top point(they are marked on the ceiling and floor);
• plaster is applied at the upper and lower points, which acts as a guideline for leveling the surface;
• a similar procedure is performed on the adjacent wall;
• so that the plaster beacons are not damaged, the mortar must harden;
• plastering is carried out near the lighthouses with subsequent processing of the entire plane.

Metal profile and drywall

Align the angle between the walls using a special curved mesh profile made of aluminum. The angle alignment process resembles the technology of using plaster mortar.

Once problem areas have been identified:

• the corner is filled with plaster;
• the profile is pressed into the solution while leveling with a level;
• excess plaster is removed with a spatula.

This method will greatly facilitate the process of leveling the corner. The only difficulty to be faced is the protruding edge of the profile. It will have to be closed with a finishing putty and sanded with sandpaper.

The use of drywall is most appropriate in the presence of fairly solid differences in planes. Doesn't help in this case. plaster layer, with which it is simply impossible to align the angle (the plaster will fall off).

Inner Corner Alignment

Let us consider in more detail the technology of leveling the corners of the walls. First, let's talk about how to align inner corner walls with putty and a perforated corner (counter-shulz).

You must first perform the following work:

• clean the entire surface greasy spots, dust and protruding concrete;
• sand corners with primer deep penetration and, if necessary, an antiseptic;
• expand the areas between the corner and the walls by 0.8-1 cm.

The consistency of the working mixture starting putty should be similar to cream (and not thick sour cream). Therefore, when preparing the solution, a little more dry mixture should be added to the water. Stirring putty can be carried out both with a construction mixer and with an ordinary metal spatula.

The process of aligning the inner corner itself consists of the following sequential steps:

• putting putty in the corner is carried out in such a way that it is located above the level of the wall;
• the distance between adjacent sections of the corner should be at the level of 15-20 cm;
• after measuring and cutting the perforated corner of the desired length (if necessary), it is pressed into the applied putty;
• the vertical position of the corner is leveled by pressing the lower or upper part of the counter-shoulder;
• removal of excess putty from the side of the perforated corner is done very carefully (it should not budge);
• within 24 hours the corner dries;
• the final alignment of the corner with the surface of the adjacent walls is carried out using a large number finishing putty;
• with a spatula, movements are made from the bottom up;
• one end of the tool rests against a corner, and the other one moves along the wall;
• after the corner has completely dried, the surface is polished with an abrasive mesh;
• all aligned corners are covered with a deep penetration primer.

Outside corner alignment

The technology of leveling the outer corners is in many ways similar to the technique of creating even inner corners. In the same way, surface preparation is carried out:

• cleared of dust;
• covered with a primer;
• large bulges get off;
• cracks and other defects are repaired.

To fasten the perforated corner, you can use self-tapping screws, which, together with the counter-shulz, are covered with putty. When applying putty at an angle (with a layer of up to 5 cm), the vertical plane is leveled with a rule.

When carrying out work, it is recommended to use a sprayer. Thanks to its use, gaps in the applied putty in opposite parts of the corner are not allowed. After the starting putty has dried, it is applied finishing material, and the corner is polished, followed by the application of a primer.

Video on how to align wall corners:

Even a novice master who has replaced experience with diligence can plaster a flat surface. When working with complex reliefs, one effort will not be enough. This requires either experience or special device- perforated corner, with which you can beat the conjugation of surfaces. We will tell you how experienced plasterers and novice craftsmen using a perforated corner align the corners.

How to level the corners of the walls with plaster and a spatula

In the room of any dwelling there will always be at least four internal and six outside corners. Internal corners are formed due to the conjugation of adjacent walls, and external corners are formed by a window and doorway. And if the walls and openings are finished with plaster, then the presentability of such a cladding will depend, among other things, on the quality of the edges at the junctions of the planes.

Therefore, experienced plasterers pay special attention to the joint of the finished planes. Moreover, to form ideal edges, real masters use only a plaster mortar and a spatula, acting as follows:

1. 1. First you need to calculate the deviation of the face from the vertical and horizontal, using the simplest plumb line.
2. 2. Next, you need to measure the perpendicularity of the mating of the planes using a square.
3. 3. After that, you need to install beacons on the plane, setting the depth of the missing layer of plaster.
4. 4. Further, having finished with preliminary measurements and beacons, the master prepares the starting and finishing (finishing) plaster mortar. If the vertical and horizontal deviations are insignificant, then you can align the corners of the walls only with fine putty, without a rough sketch of the starting plaster.
5. 5. After that, the solution is thrown onto one and the other plane and leveled with a rule, with a periodic measurement of the vertical with a plumb line.
6. 6. In the final, the corner is finely grouted with a special spatula.

At the same time, the corner alignment technique assumes the following approach to finishing: first, a plane is cast with a maximum deviation from the vertical (horizontal), after which the mortar is allowed to harden, and then the plaster is thrown onto the plane with a minimum deviation, using the frozen layer as a beacon.

In the final, the joint is brought to an ideal state with the help of finishing putty and a special spatula, made in the form of a corner. The finishing mass is applied to the wall and carefully rubbed with a corner. If you don't have an angled spatula handy, you can use it instead. common tool with a flat scraper and a rule that is set along the edge.

The scraper with finishing composition slides over the wall and the rule, forming a perfect angle on one side. Then the rule is rearranged to the other side, waiting for the plaster to dry on the finished plane, and the operation is repeated again. Moreover, success in this matter comes only to experienced plasterers, so all novice masters prefer to use a perforated corner.

How to level a wall corner with a perforated corner

With a corner, the master does not need either a preliminary measurement of deviations or a leveling beacon. It will replace both, significantly reducing the complexity of the operation. With a corner, you can align the corner of the wall by spending minimal time on this job. And in this case, you need to act like this:

1. 1. We measure the length of the edge of the joint with a tape measure and cut off the corner. Moreover, in a standard-plan apartment, one corner strip will be enough for any joint.
2. 2. We knead the solution (at least rough, at least finish) and apply a shaft with a spatula up to a centimeter deep on the very edge intended for leveling.
3. 3. We apply a corner to the plaster mortar shaft and press it down with a spatula, not forgetting to periodically check the vertical with a plumb line.
4. 4. We remove the remnants of the solution that has come through the perforation in the corner plate. Once again we check the vertical or horizontal and leave the joint alone for 20-30 minutes.
5. 5. After half an hour, we begin to plaster the mating planes, leaning with a spatula on the ledge at the junction of the profile plates.

In the end, you get perfect Smooth surface, and fine leveling wall corners (joint grouting) in this case is not necessary. The perforated insert will play the role of a beacon that does not allow the spatula to spoil the joint line.

In addition, after finishing, the perforated plates will work as a reinforcing insert. Therefore, door and window openings will not be covered with chips and cracks, which inevitably appear over time on any edges that are not protected from accidental impacts.

Moreover, with the help of a perforated plate-corner, it is possible to protect not only straight joints, but also curved surfaces formed as on inside any wall (in the interior), and on outer surface(in the exterior). To do this, you only need to select correct profile from the product range of similar products offered by sellers.

Varieties of plaster corners

In most cases, the assortment of plaster corner profiles is classified by type structural material used in the manufacture of such a product. And on this basis, the product range is divided into two groups: metal and polymer.

The metal group includes corners made of steel and aluminum. Steel, of course, is the most common (structural), but to protect the product from corrosion, it is coated with zinc. Aluminum is not subject to corrosion, so it goes to profiles without additional coating.

The planes of metal products laid on mating surfaces must be perforated. During installation, through the hole in the strips of the corner profile, the plaster appears, holding the product at the junction. In some cases, in addition to perforation of the strip metal product supplemented with a steel mesh, which guarantees a stable fixation on walls with a large deviation from the vertical.

The thickness of the strips of metal profiles does not exceed 0.4 mm, so they are readily used in contrast to thick polymer products. However, such products go only to straight joints. It is simply unrealistic to assemble an arc using a metal profile.

The polymer group includes both classic and arched corners. stripes last version not monolithic, but decorated in the form of teeth. As a result, due to this feature and the natural plasticity of the polymer, using such a profile, it is possible to beat not only a straight, but also a rounded joint (the same arch).

In addition, polymer products do not rust from the moisture contained in the plaster solution and are cheaper than steel counterparts. However, arched and ordinary polymer corners have one drawback - they are designed for applying a plaster layer with minimum depth not less than 3 mm. Therefore, it is not recommended to use such products only for finishing.

According to the design of the planes, polymer profiles do not differ from metal counterparts. They have the same footage, the width of the strips and perforation, which allows you to stick the strip on the plaster shaft. Only instead steel mesh at polymer version a fiberglass analogue is used, which, however, has a comparable tensile strength.

From the author: hello dear readers. If you do repairs - then qualitatively! One of important points finishing wall work is the evenness of the corners. Especially big role they play in the placement of furniture and other interior items. Also uneven corners indoors can visually spoil all the positive impressions of the repair. For this kind of work, certain skills are required, but it is quite possible to do everything yourself. Therefore, today we will tell you how to align the corners of the walls. different methods with minimal cost forces.

There are several methods for aligning corners. Each of them has its own advantages and disadvantages, which you should pay attention to when choosing a job.

Basic Corner Alignment Methods:

• plasterboard leveling;
• leveling with plaster;
• the use of a perforated corner (counter-shoulder).

And now let's talk about each of them in detail.

Plasterboard leveling

This method is the most convenient and acceptable for those who want to align the corners without significant repair work. fastened to the wall with dowels or an adhesive mixture, or fastening is carried out to a specially prepared frame. It all depends on the degree of unevenness of the walls.

Required tools:

• drywall;
• metallic profile;
• building level, tape measure, ruler, square;
• dowels, screws, screws;
• mounting knife, spatulas, reinforcing tape;
• perforator, screwdriver;
• primer and putty.

This type of alignment of corners has a number of advantages:

• does not require the use of plaster solutions;
• minimal preparatory work;
• drywall immediately after installation and primer can be putty.

But there are also disadvantages:

• Not recommended for use in rooms with a high degree humidity;
• drywall is fragile, it is subject to mechanical damage.

After installing drywall, reinforcing tape is used. It is recommended to additionally reinforce the outer corners by using a special perforated corner, as they are most often subject to impacts and mechanical stress in domestic process. If you are confident in the evenness and plan in the future exterior finish external corners, then the use of a perforated corner is not required. This is followed by a complete wall putty, sanding and primer.

Important: when gluing drywall to the wall with an adhesive mixture, do not allow the formation of cross-shaped seams!

Leveling with plaster

This alignment method is used when it is necessary to solve the problem of significant unevenness of the walls, and you want to make perfectly even walls and corners with your own hands. Beacons set according to the level, correctly selected and mixed plaster mix, availability and use handy tools/ fixtures is the key to high-quality productive work.

• lighthouses (metal or wooden);
• grinder for cutting lighthouses or scissors for metal;
• dowels (screws - for wood);
• primer;
• construction mixer (drill);
• gypsum dry plaster;
• rule;
• plumb (level);
• roulette;
• gloves;
• abrasive mesh (sandpaper);
• spatulas (straight wide, angled).

This alignment process requires careful preparation, as well as accurate calculations when placing beacons. So, let's consider the features of using the beacon alignment method and study the sequence of all works.

1. First you need to prepare, while before applying the solution, carry out obligatory primer the entire surface. This is done to remove dust and increase the adhesion of materials.
2. The next stage involves fastening the beacons to the walls using fasteners at a distance of the width of the rule. In this case, it is necessary to indent from the corners at a distance of 6–8 cm.
3. Next, you need to determine with the help of a plumb line (level) all vertical deviations and make marks on the ceiling and floor, according to which you will be guided in the alignment process in the future.
4. Start applying the plaster on one side, filling the space between the fixed beacons ( wooden blocks, metallic profile). Distribute the solution evenly, and after it dries, you can proceed to leveling the second wall.
5. At the stage of formation of corner joints, after complete filling of all surfaces, even corners can be obtained using an internal (external) corner spatula. To do this, it is necessary to draw a tool moistened with water over the applied putty, while forming a clear right angle of 90 degrees. Then it is necessary to remove excess plaster mixture with a metal wide spatula, moving into different sides and thereby forming a smooth transition.
6. The final leveling step is to remove the beacons and fill the void with putty.
7. After complete drying of the corners and walls, they must be sanded with a special abrasive mesh or fine-grained sandpaper.
8. Next, you need to prime all surfaces of the walls (preferably with a deep penetration primer).

Using self-tapping screws as beacons

When leveling walls and corners, for example, in a bathroom or kitchen, you may encounter a large number of pipes, and the installation of beacons will become quite problematic. In such a situation, self-tapping screws are used instead of conventional beacons in hard-to-reach areas.

In the process of work, a horizontal line is drawn on the wall, along which self-tapping screws are attached. To properly deepen them into the walls, use a plumb line with a load that is suspended from the ceiling on minimum distance from the wall, it will become your guide. In this case, the self-tapping screw must be adjusted so that its head only slightly touches the plumb line.

Expert advice: when forming external corners for gluing drywall, you can use adhesive mixture instead of the usual starting putty, because it is thicker and dries quickly enough. Therefore, further finishing work on the formation of even corners can be carried out on the same day, while saving your time.

As you can see, this method of aligning corners is not as complicated as it seems at first glance. The main thing is that this process, made by hand, will bring you not only the expected positive result but also cost savings!

Using a perforated corner

The use of a perforated corner (contrashultz) is a common method for aligning both external and internal corners. A counter-shul is a special perforated corner, which has an aluminum base.

To align the outer corners, a special corner with a reinforced mesh is mainly used.

Scroll necessary materials and tools:

• level (a plumb line is also suitable);
• roller (brush) for applying a primer;
• primer;
• construction mixer, drill;
• a clean container for mixing the mixture;
• gypsum dry plaster;
• rule;
• spatula (narrow and wide);
• construction scissors;
• perforated corners (counter-shults).

Sometimes, when performing repairs, the question arises of how to align the corners of the walls associated with the curved linearity of these junctions of the enclosing structures. There are several methods for eliminating such irregularities, both for internal and external corners.

The junctions of two walls, joints, are a rather difficult area in terms of finishing work. This is, as a rule, the final stage of work, which requires special care and scrupulousness in its implementation.

The alignment of the corners is done before the start of the finishing of the wall surface, so that the irregularities do not spoil the overall picture of the work performed, because. when pasting wallpaper or after laying tiles, the crooked linearity of the angles will manifest itself very significantly.

The ideal angle is a 90* angle between two walls perpendicular to each other along the entire vertical interface plane.

Before starting work, old finishing elements (wallpaper, tiles, finishing plates) are removed from the surface of the walls, including in the corners, essential tool and Decoration Materials.

Principles and methods of alignment

Depending on the type of materials used to finish the surface of the walls, the methods for leveling the joints also differ, which determine the sequence of work and their complexity.

Leveling method using plaster

For successful alignment of corners using plaster and putty, it is necessary to use similar mixtures good quality, having the ability to quickly set, which allows you to perform work with the least consumption of materials and in a short time.

The joints of the walls are primed, for this a deep penetration primer is used, corresponding to the nature of use (for external or internal work).

After the corners are cleaned and treated with a primer, the work is carried out in the following sequence:

• the deviation of the angle from the required values ​​is determined;
• marking is carried out on the surface of the walls at the points of their conjugation, indicating how much and in which direction a layer of plaster should be applied;
• beacons are set according to the marking;
• spraying is carried out on the exposed beacons;

Spray is a preliminary layer of plaster, the main task of which is to ensure a reliable connection between the surface to be coated and the following layers of plaster.

• excess plaster is removed using the rule;
• drying and re-priming of the applied layer of plaster mortar is carried out;
• soil is being performed;

Soil is the main layer of plaster, performed during plastering. various surfaces, regardless of its type (simple, improved, high-quality).

• if the superimposed layer is not enough to eliminate the crooked linearity of the angle, then another layer of soil is superimposed;
• after the plaster layer has hardened, it is grouted and puttyed.

Leveling method using drywall

Drywall is a building, finishing material, which is dry plaster based on gypsum and consisting of two layers of cardboard (paper), between which is placed a hardened layer of dough, consisting of gypsum and fillers.

When used to align corners, drywall (gypsum plasterboard) is a very convenient material, due to its ease of installation and ease of processing.

The advantages of using GKL are:

• No need to remove previously used finishing materials.
• There is no need to use aqueous solutions (plaster), which ensures a minimum amount of dirt when working.

The disadvantages of GKL are:

• susceptibility to external mechanical influences(fragility);
• The ability to absorb moisture.

Alignment of corners using drywall is performed as follows:

• marking is carried out, the location of the supporting frame is determined, on which drywall will be mounted;
• a frame is being installed, consisting of guides (vertical and horizontal ties) made of a special profile;
• for fastening the guides to the wall surface, special fastening elements, brackets are used, which are mounted on the wall in pre-marked places;
• when mounting vertical connections, a plumb line and a building level are used, which allows them to be placed in a given plane, and special brackets make it possible to fix them in this plane;
• plasterboard sheets are laid on the mounted frame, for which self-tapping screws are used;
• a reinforcing mesh is glued into the inner corners, and the outer corners are closed with special perforated corners made of plastic or aluminum;
• corner joints and joints between GKL sheets are puttied.

Principles on which corner alignment methods are based

The above methods for leveling corners using plaster and drywall sheets are based on certain principles of work performance.

So when using plaster, the marking principle is used, suitable for correcting internal corners and consisting in marking the junction of two walls.

As already written above, in this case, the dimensions of the mismatch of the existing angle from the required values ​​are determined, for which a special construction tool is used. Marks are made on the surface of the walls, after which they are plastered and the corners are aligned.

When using drywall and creating ideal outer corners, a perforated corner is used, which has a special name - countershulz.

Work with its use is performed in the following order:

• the corner is cut in accordance with the height of the room at the place of its installation;
• a plaster mortar or putty is being prepared;
• the prepared mixture is applied to the installation site of the corner;
• countershulz is installed on the prepared surface, while using building tools(level and plumb) its location in a given plane is controlled;
• excess solution is removed with a spatula;
• the surface is rubbed and puttied.

Features of performing certain types of work

The methods for performing work on the alignment of internal and external corners are somewhat different from each other, which determines the methodology and sequence of their implementation.

This is the most difficult option pairing two walls, so if possible, it is better to turn to professionals in order for them to do this work. It is especially difficult to level inside corners when using the mortar leveling method.

As mentioned above, it is important right choice plaster, capable of providing the required adhesion to the wall surface and quick hardening, which ensures that the solution does not drip when applied to the walls.

Do not forget about the use of a reinforcing mesh and the possibility of installing a perforated corner of the appropriate profile (inner corner), which will also facilitate the completion of finishing work at the joints of the walls and ensure the strength of the structure.

If there are no skills to perform such work, then in order to achieve good result, it is necessary to carry out work with special care and attention, first of all, it concerns the marking.

Alignment of external corners

Alignment of external corners is easier to perform than internal ones. This is due to the fact that a special perforated corner is used for alignment, counter-shultz, during the installation of which the most important task is to maintain its location in the required plane of space.

The fastening of the counter-shoulder can be done, as described above, using a plaster mortar or putty, as well as using self-tapping screws or expansion dowel-nails when the wall is finished using a plaster mortar.

The use of aluminum and plastic corners due to the fact that during operation they are not subject to corrosion, thus there are no oxidation processes that could manifest themselves through the finishing material laid on the wall surface.

Corner alignment is hard work, so starting to self-fulfillment, you must be aware that for its successful implementation, painstaking work will be required that does not require fuss and haste. Just doing it right necessary measurements and having selected the appropriate materials and tools, you can count on success in such an undertaking.

Flat corners - sign 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 in 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 detected before finishing walls should be removed.

This is especially true when it is planned to stick wallpaper with a pattern in the room or to carry out installation ceramic tiles- with these 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. bumps 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 for correction wall joints even a beginner can do it.

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 tiles: too smooth surface will not provide a 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 is not expected additional costs, alignment of wall joints can be omitted.

In other cases, setting 90º is essential part of the renovation, because some modern furniture and technology requires only such a foundation.

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 mixtures High Quality 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.

Most convenient way work involves gypsum plaster or starting. This option will allow you to make a correction using the most thin layers and without sagging.

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

1. Roller or brush for priming the base;
2. Spirit level of any type, as well as a plumb line;
3. The container in which the plaster will be mixed;
4. Drill mixer;
5. Rule;
6. Wide and narrow spatula;
7. Primer for the base;
8. 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 right amount plaster mix.

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 will be held Finishing work. If it is planned to finish the corners located outdoors or in rooms with high humidity, it is worth choosing 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.

Gypsum board as a means of achieving an even joint

Gypsum boards for leveling corners are 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 permanent high level 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:

1. Carry out the installation of guides that will serve as the basis for drywall sheets;
2. Sew up the GKL frame with self-tapping screws or screws;
3. Apply reinforcing tape to reinforce internal corners;
4. Align perforated aluminum corners for outside corners;
5. 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. Besides, given 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 works on alignment drywall is not used. For external corners, only dry building mixes are suitable.

1. First you need to check the outer corners for evenness. All protruding irregularities must be removed with a hammer.
2. The next step is to prime the walls with special formulations deep impregnation.
3. 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.
4. Excess mixture must be removed with a spatula. Then you need to make sure that vertical installation metal profile.
5. 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.
