DIY wall corner repair

In detail: do-it-yourself wall corner repair from a real master for the site my.housecope.com.

Each apartment renovation is accompanied by the obligatory alignment of the corners. This procedure can be performed in different ways, you just need to carefully follow the work technology. The process is quite laborious, and not every beginner will be able to cope on their own. This article will discuss how to align the corners of the walls and what tools and materials to use for this.

Smooth surfaces and corners in the home are a symbol of a well-executed renovation. Any defects will be very conspicuous, especially curved walls, if not covered with furniture or decorations. To get rid of the imperfections, you will need to pay careful attention to aligning the corners.

The work will require certain knowledge and skills, so it will be difficult for beginners in the construction business. How to align the corner of the wall? There are various methods of aligning them, differing in the technology of work, the required materials, tools and other factors. The main ways are:

alignment with drywall sheets;
work using plaster mortar;
the use of perforated corners made on the basis of aluminum;
the use of marks that are determined by the level or plumb line.

Before you start aligning the corners, you will need to prepare your work surface. This requires:

Clean the wall of various finishes such as old wallpaper, paint or tiles.
The surface is treated with a primer. This will increase the strength and prevent the formation of mold or mildew.
When using cement mixtures, the corners will need to be cleaned and moistened before applying the solution.

Experts perform such procedures without much difficulty, especially if the surface has been well plastered. To align the corners of the walls with your own hands, you will need the following tools:

laser or water levels (plumb line);
a roller or brush for priming;
drill and construction mixer;
container for preparing the mixture;
primer;
building rule;
dry plaster mortar;
perforated corners;
low and wide spatulas.

The alignment of the corners of the walls with plaster is carried out in order of priority:

The corner is being cleaned and prepared for work.
The vertical level is determined using special beacons.
The first layer of mortar is applied to the wall.
Surfaces are being putty.
The corners are leveled with putty.

You need to start leveling the corners only after plastering the surface. The application of the mixture in the corners is carried out with brushes. This tool will allow you to process even inaccessible areas.

With the help of the following video, you can familiarize yourself with all the intricacies of leveling with plaster:

Many experts use a special plaster solution that dries quickly and does not fall off surfaces. Its use will significantly speed up and simplify the alignment process.

Plasterboard alignment is often used if the walls have not been pretreated. This method will allow you to align the corners without major repair procedures. Installation of sheets is carried out using glue or dowels. You will also need the following materials and tools:

spirit level;
drywall in the right amount;
spatula for sealing joints;
gypsum-based glue;
tape measure for material measurements;
construction knife for trimming drywall.

This method has a number of advantages before using plaster:

There is no need to make a plaster mix.
When installing drywall, you do not need to clean the wall from the old finish.
After installing the sheet, the surface can be immediately putty, there is no need to wait for the plaster to dry.

The process of installing drywall in corners

There are also a small number of disadvantages. This method cannot be used when treating a room with a high moisture content. In addition, drywall is a rather fragile material and is highly susceptible to damage. The process of installing drywall can be seen in the following photo.

With the correct installation of drywall, additional alignment of the corners is not required.

After installing the drywall, the work area is plastering with reinforcing tape. If the outer corner is leveled, the best solution would be to use perforated corners, which can be simply covered with a putty.

When installing drywall, you need to ensure that no cross-shaped holes form at the joints. In any case, before the mortar hardens, the sheet can be leveled with a hammer or level.

The drywall installation diagram can be seen below.

Internal corners are often aligned using marks. The sequence of this procedure is as follows:

The walls are marked with a level.
A solution is prepared for processing.
A layer of the mixture is applied according to the established marks.
Using a spatula, the mixture is leveled and evenly distributed.
After the solution has dried, the next working area is processed.

The process of high-quality alignment of corners is quite difficult, so it is not always possible to achieve the desired result. It is extremely important to align the corners as much as possible before laying the tiles, since with such a material any defects will be quite conspicuous.

The alignment corners are the optimal solution for renovations. They are perforated products with an aluminum base. They can be used to seal both the outer and inner corners. The design of the product will protect the surface from various damages.

The procedure for such alignment consists of the following steps:

After purchase, the structure is cut to the specified length.
A plaster mortar is prepared until a homogeneous mass is created.
The mixture is applied to the corner. When aligning the inner corners, the composition is distributed along the entire length. For external treatment, the amount of solution is adjusted according to the requirements.
The corner is being installed; you will need to carefully monitor the evenness of the installation.
Excess mixture is removed with a spatula.
After installing the corners, they will need to be aligned with the wall.

Installation of corner aluminum structures

So that the corners do not stand out against the background of the wall, it is necessary to apply the solution at a distance of about 50 or 80 cm from the corner. The entire mixture should be evenly distributed and smoothed over the surface with a wide trowel. After the mortar dries, the wall is primed. For greater efficiency, you need to use a putty that will hide all defects. You can see the aluminum structures in the next photo.

Repairing the outer corners is not very difficult, the main thing is to adhere to the instructions. For such work, a special corner with a reinforced mesh is used. Its installation is carried out using self-tapping screws, after which it is treated with plaster.

Aligning inner corners is the most difficult procedure

Another method of leveling is the initial application of the plaster, which must be carefully spread over the entire surface. A corner is installed on it. For reliable installation, it is screwed on with self-tapping screws and pressed into the applied mixture. Places of the protrusions of the composition are neatly smeared. If necessary, add more mortar to completely mount the product into the wall.

Aluminum structures are used to prevent the material from rusting. They are flexible and easy to use. During procedures, a level check should always be carried out to prevent possible unevenness.

This procedure is already more complicated than when leveling the outer surfaces. The employee will need skills and experience, so this process is extremely difficult for a beginner. The method begins with leveling the surfaces and checking with a level. If all measurements were done correctly, then the result should form an angle of 90 °.

When working with corners, it is not always possible to achieve sharp symmetry, since the corner is often slightly rounded. This happens when using aluminum corners.

Some craftsmen use a special method, which consists in the use of 2 spatulas set in parallel at an angle. This allows you to get rid of all errors when using the plaster mixture.

As you can see from the article, the alignment procedure is not too complicated, but it requires experience. If the work is carried out by a beginner, the result may not meet expectations. With the help of a photo, you can practically see such processing and implement it in your own home.

The question of even walls is one of the most important when it comes to finishing work. But it is equally important when the corners in the rooms are even at 90 °. Therefore, the question of how to level the corner of the wall with plaster mortar is one of the most frequently encountered on the pages of construction forums. The rooms always have both internal and external corners. Therefore, it is necessary to understand the two alignment processes that are slightly different from each other.

Please note that leveling with plaster is best done if the size deviation from the straight line is not very large (87 ° -92 °). If this figure exceeds the standards, then it is best to use drywall for leveling.

Outside Corner Alignment

Let's start by asking how to align the corners of the walls (outside)? Usually they are located at the door, rarely when there is a column or architectural protrusion in the room. But in any case, they must be adjusted to fit a straight line.

The deviation is determined first. For this, a square is applied to the corner. The longest part of the tool should rest on the main wall, which should already be plastered. Usually a ledge is fitted under it.
If the angle is sharp, then the adjacent surface must be leveled.
First, plaster beacons are installed - evenly over the entire height.
Then plaster is applied to the adjacent wall. That is, the wall surface and the outer corner are leveled at the same time.

Aligning the inner corner

The solution to the question of how to align the inner corner of the wall is more complicated. Sequence of work:

A metal profile is installed on one of the walls at a distance of the width of the angle trowel blade, which is fixed to the wall with three metal dowels. Installation should be carried out strictly vertically, for which a level is used.
A plaster mortar is applied to the adjacent wall with a flat small spatula. Apply the plaster with small strokes to the entire height of the corner to be leveled.
Now it is necessary to level the mortar with an angled spatula so that the gap between the blades of the tool and the wall surfaces is completely filled with plaster.
The profile is dismantled, it is waited until the applied layer dries up, after which it is necessary to prime the corner and carry out additional leveling with a thin layer of putty.

As you can see, plastering the corners of the walls with your own hands is not the easiest process.But if you understand it, it turns out that doing it yourself is not a problem.

Construction technologies today are rapidly changing, moving into the category of "easy to implement". Therefore, the question of how to plaster the corners of the walls can be solved in a simpler modern way. To do this, you need a special part - a metal counter-shell. Basically, it is a square corner made of aluminum, to which a mesh is attached. Konrashultz is used to form corners.

In order to install it, it is necessary to apply plaster mortar with a thick layer right into the corner. It is better if it is thick. After that, this mesh corner is installed on top of the not dried plaster. Please note that the vertical position of the Konrashultz is a basic requirement. The metal corner itself is a soft part, so it is best to use a long rule to press it down to the corner of the room.

At the same time, part of the plaster solution that must be removed is squeezed out from under the leveling device. Now it takes time for the solution to dry well. The rest of the angle alignment process is carried out using standard technology. In fact, this is the usual alignment of walls adjacent to each other. That is, first one wall is aligned, then the other. In this case, the Konrashultz mesh will be inside the applied layer of plaster, which will make the mortar stronger. And the metal angle will provide 90º.

So, in this article, answers were given to the question of how to make an even corner of the wall with plaster (external and internal)? To finally understand this issue, we suggest watching the video posted on this page of the site.

For the convenience of laying the plaster, the slots expand

Old paint can be removed with a grinder. Too large nodules are more convenient to remove with a punch. If these influxes are left, then you will have to focus on their height, and you will have to apply the plaster in a very large layer. For it to adhere perfectly, the walls must be cleaned of dust and prime.

It is worth measuring the walls with a building level. If the differences are too large (more than 4 cm), it is better to align the walls with drywall... Otherwise, the cost of plastering will be too high.

It is more convenient to remove old paint with a grinder

1. Before drawing a corner, align the adjacent walls. When aligning all four corners, work is in progress round... First, one of the walls is aligned, then the corner, then the next wall, etc. With this method, the probability of damaging the drying plaster is minimal.

2. If the height differences are large enough, it is better to use beacons... To place them at a distance of 20 cm from the corner, a straight horizontal line is drawn. Along it are superimposed "Brands": slaps of thick mortar applied every 30 cm.

Applying plaster "marks"

3. Further, it is pressed into them Lighthouse: a strip of plastic or metal with holes for extruding the grout. The indentation depth of the beacon is checked building level... If the applied solution is not enough for leveling, the plaster under the beacons is reported so as to achieve perfect leveling.

Installation of beacons

4. The distance between adjacent beacons should be equal to the width regulations: tool for leveling plaster in the form of a trapezoidal strip of metal 1-3 m long.

5. For additional control along the top and bottom of the wall, you can pull the nylon thread. It is attached to dowels screwed into adjacent corners. In this case, the depth of indentation of the lighthouse is adjusted so that the thread only slightly touches its surface.

Align with thread

6. After the lighthouses have dried, plaster is laid between them and leveled using a rule.

Aligning the wall with a plastering rule

7. It will not work to even out large differences the first time: the mixture must be applied several times.

Advice... At one time, you can apply only a couple of centimeters of the solution: if too large a layer is built up, it will crack after drying. To prevent cracking, layers that are too thick can be bonded with reinforced mesh, which is pressed into the solution.

Plaster mesh

8. In too difficult places between the main beacons, you can install intermediate... Often installed beacons will make the job easier with too long a rule.

9. To make it easier to align the corners, you can use plaster corner profile... It is a strip of metal or durable plastic bent at an angle of 90 °, on both sides of which a reinforced mesh can be fixed. After leveling the first wall, the required amount of plaster is laid in the corner, and then the profile is pressed into it. After checking with a level, its excess is removed with a spatula.

Corner profile with mesh

10. You can also ideally level the corner using a special construction tool - an angle trowel.

Leveling with an angled trowel

11. After plastering the first wall, wait until it is completely dry. Further, with the help of beacons, the second wall is leveled.

1. When leveling walls and corners in the kitchen, in the bathroom, installing beacons can be problematic due to the large number of pipes. In this case, most of the wall is leveled using ordinary beacons, and in difficult areas they use self-tapping screwswhich are superimposed "Brands" (mortar slaps).

2. In the same way as when installing conventional beacons, a horizontal line, along which self-tapping beacons are attached.

3. Since it will be difficult to adjust the depth of their screwing with the help of a level due to protruding pipes, they use plumb lines... To do this, a dowel is screwed into the ceiling at a minimum distance from the wall, on which a thread with a load is suspended, which will serve as a reference point.

4. The self-tapping screw should be adjusted so that its head is only slightly in contact with the plumb line.

Exposing self-tapping beacons

Advice. Since the metal self-tapping screw can rust over time, and the rust will peep through the wallpaper or other finishing material, after the plaster dries, it is better to carefully unscrew it.

Outer slopes are easier to align. For these purposes, apply plaster perforated corners made of metal or plastic. They will not only help to perfectly align the corners, but also protect them from collapse upon impact.

The corner is fixed with a putty, into which it is pressed into, and then leveled by level... Excess putty is removed with a spatula. Next, the wall itself is plastered, while the corner is used as a beacon.

Corner alignment

Angle skew too great

To compensate for too large distortions, use a different method. On one side of the wall, the level is set lighthousesfrom which the wall aligns towards the corner. After the first wall has completely dried out, the second is leveled in a similar way. Both walls are leveled and form a perfect angle. Its final alignment is done using angle spatula.

Leveling with an angled trowel

Each renovation process requires completeness, which consists in leveling the corners of the room. In the article, we will consider the main methods, features and sequence of work with different materials, as well as provide a list of the necessary tools and devices.Smooth corners and walls are the subject of professional and high-quality repairs in an apartment or house. All errors and imperfections are very easy to notice, especially a curved surface that you cannot cover with furniture or fill with decorated elements. To remove all imperfections, it is important at the initial stage to pay special attention to aligning the corners.The process of performing work requires certain skills and abilities, and therefore it will be quite difficult for beginners to do everything with high quality. There are different ways of aligning corners, each requiring an individual approach and implementation, a list of necessary fixtures, and so on. So, the main alignment methods are shown:

works with the use of drywall;

leveling with the use of plaster;

with the assistance of a counter-shell, which is a perforated corner made of aluminum;

using marks, which is determined by the level or plumb line.

Before getting into the issue of aligning the corners of the walls, it is important to prepare the workspace area. To do this, you should do the following procedures:1. We clean the surface of the wall from various coatings, for example, rip off old wallpaper, remove whitewash, knock down tiles, and so on.2. Cover the base with a primer.3. For working with cement mortars, it is recommended to thoroughly clean the corners, and it is important to moisten them with water before application.For specialists in this field, the process of aligning the corners is not difficult, especially if the walls were evenly plastered. For high-quality work, it is recommended to use the following devices:

laser or water level, can be replaced with a plumb line;

roller and brush for applying a primer;

drill and construction mixer;

the container in which the solution is prepared;

primer;

rule;

dry plaster mix;

putty;

perforated corners;

it is recommended to use a spatula low and wide.

Work on leveling the corners with plaster is carried out in turn, while you need to remember the sequence of applying layers and processing the wall:

we clean and prepare the base for work;

we determine the vertical level using plaster beacons;

apply the first layer of plaster to the surface;

we carry out putty on the walls;

align the corners in the room with putty.

To facilitate the leveling process, certain beacons are used, which are attached to the surface to be treated with plaster mortar. In this case, the use of fasteners is inappropriate.1. The wall must be divided into parts approximately 1 or 1.5 meters vertically.2. First, the construction beacon is fixed in size and a small layer of plaster is applied to it, which will allow the object to stick to the surface.3. The first mark should be 10 cm from the corners of the filler, and in the other area the mark should be in the same position. All beacons must be level tested.4. The next step is to drive nails into the holes of the beacons. A cord is pulled between them in the upper corner and in the lower one, along which marks will be installed further along the entire width of the wall. After installing beacons, all additional elements are removed.5. Plaster the walls for the final alignment of the corners.Features of the work are in the alternate processing of the walls. After that, you need to wait a while until everything is dry. On another wall, beacons are applied in the same way, and then they are plastered. If in the process of work, errors are made, the next stage of coating with putty will eliminate all defects.Plastering the surface, you can approach the correct formation of the corners. The work is more difficult to perform if you do not plaster the walls, then the process of performing the work is shown to be more painstaking, especially for the inner corners. Some experts recommend using a special mixture of plaster, which dries faster and does not fall off the walls, which reduces the time spent on work.In most, the do-it-yourself method of aligning the corners of the walls using drywall is suitable for builders who do not process walls. In this case, a technology is used that will allow you to accurately align the corners without large-scale repair work. Gypsum plasterboard is dry plaster in plaster form. Sheets are attached with special glue or dowels to the surface to be treated.In the process of work, the following devices will be required:

building level, which is called a spirit level;

drywall sheets in the required quantity;

spatula for filling material joints;

special gypsum glue that fixes the position of the sheet;

tape measure for measuring the required pieces of drywall;

knife that will be used to cut sheets.

This method has its advantages over using plaster:

there is no possibility to prepare mixtures and solutions of plaster mass;

when installing drywall sheets, it is not necessary to clean the old surface from wallpaper or whitewash;

after fixing the gypsum board, the wall can be immediately putty, and not wait time for the plaster to dry.

In this method, it is possible to separate some disadvantages, for example, it is unacceptable to use this technology in rooms where there is a significant level of humidity. At the same time, drywall is fragile in its structure and easily lends itself to mechanical damage. With the correct installation of the gypsum board, there is no need for additional alignment of the corners.After installing the drywall, the working space is putty, and it is necessary to use a reinforcing tape. When leveling the outer corners, it is recommended to use special perforated corners that can be easily puttyed. In the case of a high level of unevenness of the surface of the wall, it is advisable to use two methods. For this, drywall is installed on the wall, and after it dries, the necessary layer of plaster is applied to level the base.Important! When gluing drywall to the wall, you need to make sure that no cross-shaped seams appear at the joints. In any case, before the material hardens, the gypsum board can be leveled using a hammer or level.This method foresees the mandatory use of a plumb line or level, which is recommended when aligning the inner corner. The sequence of work is as follows:1. We put marks on the walls, preferably evenly and using a level.2. We carefully prepare the mixture for application.3. At the set mark, carefully apply a layer of plaster to the corner.4. Using a spatula, level the mortar and distribute it evenly over the surface.5. After the corner has dried, the same actions are carried out at the next working area.It is worth noting that the procedure for perfect alignment of the corners is quite laborious, and therefore it can be difficult to achieve a good result. In most houses and apartments, opposite walls can deviate from the level by 5 or even 10 cm, but for the room to have a truly rectangular shape, it is necessary to apply a significant amount of putty. It is especially important to achieve alignment for laying tiles in the bathroom or kitchen, where all errors will stand out.Corner alignment is one of the ways to carry out repair work. Kontraschulz is a special perforated corner with an aluminum base. It is used both for aligning internal corners and for external ones.It is recommended to attach the device to the outer corners, which will save them from various damages, including mechanical ones. If you inaccurately align the corner vertically, then the corner will still come out even.The workflow consists of the following stages:1. Prepare the corners and cut them to the required length.2. Mix the plaster until smooth.3. Apply the solution to the corner. When leveling the inner section, the mixture is applied completely along the entire length. When applying the mortar to the outer corner, the amount of plaster is reduced as needed.4. We carry out the installation of the corner, while it is important to monitor its vertical position, which should be even.5. Excess plaster is removed with a spatula.6. When the countersulci are installed, it is important to align them with the wall.To ensure that the corners do not differ from the wall, it is recommended to apply the mixture approximately 50 or 80 cm from the corner. Using a wide spatula, the entire mortar should be evenly spaced and smoothed over the surface. After the plaster has dried, the wall is treated with a primer. For greater effect, you should use a putty that will cover all errors.This work is not difficult, the main thing is to follow the instructions correctly and follow all the recommendations. To perform this technology, you should use a special corner on which there is a reinforced mesh. The peculiarities of its attachment are with the help of self-tapping screws, after which the surface is covered with a layer of plaster.The profile of the alignment of the corners in a different method foresees the application of a layer of plaster, which is important to evenly distribute over the surface. A corner should be attached to it. For reliable fastening, we twist it with self-tapping screws and press it into the applied solution. The plaster that has come out is gently smeared. If necessary, you can add more mixtures to completely seal the corner and mesh.Important! Aluminum corners are used to prevent the metal from rusting, while they are very convenient and flexible to use. Always check all work with a level to avoid unevenness.The technology of aligning the outer corners does not present certain difficulties, which cannot be said when forming the inner ones. In this case, specialists will need precision and skill, and for beginners this is not at all a feasible amount of work. Basically, the method should start by leveling the walls and checking them with a level in sequence. If at the beginning of the work all measurements were correct, then at the end an angle of 90 degrees should appear.To understand the technology, it is suggested to watch the video of aligning the corners at the end of this article. Working with special corners, it is not always possible to form an acute symmetry, since the corner is usually slightly rounded. This results from the use of an aluminum profile.Some experts recommend using a special method that involves the use of two spatulas, set parallel at right angles. In such cases, the result justifies an unusual method. This allows you to finalize all errors and work when using plaster mortar. After that, it is worth continuing to putty the wall.When finishing corners, it is worth remembering the peculiarities of the plaster mixture that you buy. Pay attention to its characteristics and scope.For example, for bathrooms, it is preferable to choose mortars based on a cement component, and for ordinary rooms with a uniform temperature, it is advised to buy gypsum mixtures. In the first case, it is important to putty the surface, and in the second, this is not required.In fact, all jobs are not difficult, but they require practical skills. After all, if this is your first time aligning the corners, then you need to remember that the end result may not be justified.If you have extra finances, it is still recommended to resort to the help of specialists, especially if you are not sure of your capabilities.

It is generally accepted that decorating walls with your own hands is much easier than correcting the ceiling, 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 of cases when it is planned to stick wallpaper with a pattern in the room or to install ceramic tiles - with such finishing options defects in corner surfaces will be obvious.

Depending on the type of finish, a leveling method is selected - it can be carried out either using gypsum plasterboards or using dry mixtures. Corner irregularities are corrected using either the lug or level alignment method.

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 intended.

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

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

You can align the corner surfaces using plaster or putty, drywall sheets and a perforated corner with mesh.

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

Sometimes it's worth pondering - Is it so important to bring the wall joints to perfection? To answer this question, you need to understand how important in this case is the precise setting of corner joints at 90º.

In some cases, when only a cosmetic renovation of the interior space is planned and additional costs are not expected, the alignment of the wall joints can be omitted.

In other cases, the 90º setting is an integral stage of renovation workas some modern furniture and appliances require only such a foundation.

After the decision on alignment has been made, it is necessary to carefully measure the angular misalignment.

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

Next to the ruler, you should lean a 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, you can measure deviation from an even angle in the horizontal plane, however, in this case, a longer ruler or profile is necessary: horizontal distortions, as a rule, are of less importance, therefore, a greater distance is required 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.

The most common and effective alignment methods are varieties in which dry mixes and drywall sheets are used. The method of eliminating defects using a perforated corner has also proved to be quite effective.

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

For corner correction to be successful, you need to use high quality mixturesproduced 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 starter putty... This option will allow you to make corrections using the thinnest layers and at the same time without sinking.

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

A 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;
Base primer;
Dry leveling compound.

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

Leveling must be done in the case when the surface will be finished with tiles of any kind. In the case of painting or wallpapering, plane alignment 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 the internal joints, gypsum-based plasters can be used.

The order of work consists of the following steps:

The walls are cleaned of previous coatings and various contaminants;

After that, a cement mortar is prepared to level the walls;

The next stage is priming the corners with deep penetration compounds;

The next step is the installation of beacons, after which spraying is carried out. With the help of the rule, excess mixture is removed;

Next, the layer must be dried and primed again;

Next, another layer is applied for leveling. Often, adjustments are made in two layers. After drying, the layer must be wiped off.

In the event that the walls are erected exactly, the angle after alignment is obtained by itself. For more convenient work performance you can use the contrashultz - special metal corner with perforation.

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

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

Video instruction on how to properly putty the corners:

Plasterboard for leveling corners is a very effective tool. They apply then when leveling with plaster cannot give a high-quality result and have many advantages over plastering:

GKL does not require removal of old wall coverings;

They do not require mixing dry mixtures and the whole process proceeds without dirt;

Plasterboard can be putty directly after installation.

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

If the walls of the room are originally lined with gypsum board, correction of the corners is not required. In the case when it became necessary to level the walls with plasterboard, it is necessary:

Carry out the installation of guides, which will serve as the basis for the sheets of drywall;
Sew up the plasterboard frame with self-tapping screws or screws;
Apply reinforcing tape to strengthen the inner corners;
Align the perforated aluminum corners for the outer corners;
Putty the joints.

A heavily heaped wall requires a combined method, which includes both plasterboard finishing and leveling with a plaster layer.

The metal leveling corner is used where external and external corners need to be reinforced. In addition, this material greatly facilitates the work of exhibiting perfect corner joints... In any case, the corner where the perforated corner with the mesh is mounted will be perfectly flat.

In order to set up such a corner, you need:

Cut the material to the required length;

Prepare a mixture for plastering;

Expose the corner;

Apply a layer of putty on it;

Check the level with a spirit level;

In case of flat installation, remove excess mixture;

Let the corner dry and clean.

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

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

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