How to level a wall corner

A smooth surface is a sign of high-quality work by plasterers and putters.

It can be glued with various wallpapers, covered with paint, covered with panels or ceramics. If there are no workers, how to level the corner of the wall, make the surface even and smooth?

To make angles at 90 degrees, materials, tools and certain skills are required.

Why is it necessary to align the corner of the wall?

Smooth wall joints in the room – neat appearance. If crooked walls can be hidden behind wallpaper and paintings, then the corners will make the room untidy.

Craftsmen consider another disadvantage of curvature to be the difficulty of installing tiles, gluing wallpaper, and other finishing coatings. To align the joints of the walls you need to work hard, however, in the future this will be reflected in the appearance and neatness.

How to align the internal corners of the walls in a room with your own hands

To align the internal joints, it is necessary to carry out preparatory work.

1. The cleaned surface of tiles or wallpaper is checked for the presence of voids under the plaster. It is necessary to tap the adjacent walls from the ceiling to the bottom. If the sound changes (empty), it is better to roll off the plaster. Otherwise, it may fall off on its own along with the topcoat. Another sign of emptiness is small cracks, running horizontally to the floor.
2. After the coating has been collapsed, all debris is removed. This is dusty work, but it will not interfere with subsequent work.
3. Clean everything from dust and small pebbles with a dry brush. To reduce dust, you can spray the area with water from a sprayer.
4. Next, the surface is coated with a primer, preferably 2 times.
5. A plumb line is lowered from the ceiling to the floor to determine the curvature. If large deviations are detected the best option is drywall. Otherwise, the plaster layer will have to be applied several times, each dried layer being primed.

The internal corner can be aligned using several methods. In addition to drywall, ordinary gypsum or cement plaster, beacons, and corner spatulas are applicable.

How to level previously plastered walls in an apartment

If the wall is crooked, then leveling the joint will be a waste of work. Curved plastered walls must be identified by the percentage of curvature. This can be done by a level, a plumb line, a rule. The walls are aligned in a circle.

Materials used for leveling walls:

1. Drywall. At large differences use frame metal base. If the walls have a slight curvature, then gypsum boards are glued to the surface.
2. Chipboard. Plates are suitable for leveling not very curved surfaces.
3. Panels. When leveling walls, use frame base.

Depending on the room, humidity and temperature changes, the desired material is selected.

How to display a 90 degree angle on walls

When plastering walls yourself and leveling joints, use a plaster corner profile. It can be metal or plastic. On the sides of the corner there is a reinforced mesh. The profile is applied to the wet plaster and leveled using a level. The reinforced mesh is covered with a plaster mixture.

The joining surface can also be made smooth using an angle spatula. It has a perfectly even shape. Without any effort, it can be used to create a 90-degree joint between walls.

It’s difficult to get 90 degrees on your own. This is only possible with small differences, where putty is applicable.

What materials are used to level wood?

The wooden surface also needs pre-treatment followed by leveling. You can level a wooden surface using the following materials:

1. Drywall. For installation, you must first measure the degree of curvature, then take measurements and calculate the materials. The frame base is created from wooden slats or metal profiles. For durable frame make transverse stiffeners. Fixing gypsum boards in the corners is done using several technologies. The joints of the walls are smooth at 90 degrees.
2. Chipboard. They are also mounted on a frame base made of wood. All elements are treated with drying oil or antiseptic agents.
3. Plywood 6-9 mm. It needs to be processed. The material is mainly used for leveling surfaces in the garage, pantry, country house. A wooden frame is also created for fastening.

Afterwards, the created surface with even corners is puttied, primed and covered with finishing material - wallpaper, paint, tiles.

And also the walls and their joints of a wooden house are leveled with materials:

• putty – layer of applied mixture 2 mm. Before applying putty, you need to treat the walls;
• cement mortars - applied to rough surface or they pre-fill shingles or large mesh;
• use of corners. If the walls are smooth or have slight differences, metal or plastic corners. In this case, after a second layer of putty, the angle is 90 degrees.

Cement mortar shrinks. When applying a thick layer, care should be taken to ensure that the created plane does not flow down.

How to make the outer corners of walls smooth

Crooked external corners are the result of hasty work by builders. To align them, you must first determine the degree of curvature. Another reason for leveling is frequent impacts from sharp and heavy objects.

Materials and tools will be used for leveling. A level is also required.

What you need

To work, you will need a perforated corner, a putty or plaster mixture based on gypsum, a primer, regular and corner spatulas.

The work is not difficult to carry out if you have everything you need “at hand”. Even the most curved joining surface can be created at 90 degrees without much effort or time.

How to align wall corners at 90 degrees using a corner

An outer corner is easier to align than an inner one. For this, a perforated metal corner is used.

1. First, the surface is cleaned and coated with a primer.
2. Afterwards the degree of curvature is determined.
3. Plaster or putty gypsum mortar is applied to the corner on both sides.
4. The corner is pressed into it and leveled using a level.
5. Allow time for the solution to harden. All excess mass is removed. Level the sides with a spatula.
6. After drying sandpaper you need to remove the excess and apply a thin layer of the solution again. At the same time, the work is done carefully so that there are no tubercles.

The final step is sanding and applying primer for a finishing touch.

A perforated corner will not only level the angle at 90 degrees, but also protect the surface from impacts.

How to set a 90 degree angle when plastering walls

If the angle has a large percentage of curvature, then a different method is used. A lighthouse is placed on the wall from the joint in the opposite direction. Alignment goes away from him. Thus, the adjacent wall is leveled. Smooth walls form an angle of 90 degrees. The final leveling is done with an angled spatula.

Ways to check the 90 degree angle between the walls inside and outside

There are several ways to check how straight the angle is. So:

1. A square is the easiest way.
2. The second method is to create a corner from a profile. Measure 30,60,90 cm from the corner along one wall. The length of one side of the profile will be equal to 90. To the other side on the adjacent wall, set aside 30,60,90,120 cm. The length of the second side of the profile corner will be equal to 120 cm. From one point where set aside 90 to another point 120 there should be a distance of 150 cm. The sides of the profile are connected with screws at 90 degrees. The edges are connected with another piece of profile equal to 150 cm. With this corner, the internal corner in the room is measured in several places.
3. The outer corner is measured according to the same scheme, only all marks are marked on the floor. That is. From the outer corner on the floor you need to set aside a length that is a multiple of 4. Let’s say 1.6 meters. It is laid along one wall. Next, along the other wall you need to set aside 1.2 meters. There should be a distance of 2 meters between the end points. If so, then the angle is 90 degrees. If not, then alignment should be applied.

Before you start aligning the joints of the walls, you need to find out how much deviation or curvature they have. For leveling, drywall, plywood, conventional putty, and perforated corners are used. To derive an exact beautiful angle, you need to stock up on materials, tools and a little mathematical knowledge - the Pythagorean theorem.

Repairing walls is a process that almost every person encounters in their life, but not everything is studied in advance detailed information and draws up a project according to which all work is carried out. For this reason, unpleasant situations arise associated with the inability to perform this or that work.

For example, most people have no idea how to plaster corners, despite the relative simplicity of this work. The only difficulty is using suitable tools and strictly following all instructions. Let's look into this issue.

People who do not understand how to plaster the corners of walls may not understand what we are about to talk about. The fact is that there are two types of angles - internal and external. First, it’s worth discussing the process of plastering the external corners, because this process It is considered simpler, and any beginner can handle it on their own.

Experts advise leveling the plaster on external corners using special corners - the latest tools, to facilitate the process repair work, acting as beacons. Glued can also be used for this, which is also an incredibly attractive option for use.

The fact is that plastering using corners can boast a large number of advantages, despite which, unfortunately, it is often not recognized by builders with extensive experience. Here is a list of these advantages:

• the plaster will definitely not crumble, thanks to the steel beacon that strengthens the coating;
• you can make the coating monolithic with the help of additional reinforcing mesh, because it will very reliably connect the two walls;
• you will no longer need to carefully smooth out the external corners, because the lighthouse will be pre-set to the required level, which will become the zero point in the process of plastering the wall;
• the time that will be spent on plastering external corners along the beacons will not even compare with what you would spend on simple plastering without modern means.

Let's start work

To begin work, you need to find the place on the wall that protrudes the most. We are, of course, talking about those irregularities that cannot be leveled or eliminated in any other way. This point will become the starting point for the entire process.

Please note that absolutely all beacons must be installed strictly at the same level. Otherwise, there is a high risk of getting uneven wall as a result. You can check the installation using the rule of a sufficiently long length. Just apply this tool to the outermost beacons, and then check that all the others fit tightly enough to it.

The corner can be plastered only after such work has been completed (all beacons must be well fixed). Any experts will tell you: “First we plaster the corners, and then we just go over them with sandpaper.” It is important to choose the right angles used for this process. Different types suitable for various situations. If after the plastering process you are going to start gluing wallpaper, then you should use sharp corners.

As for decorative plaster, a rounded version will look better. As you may have already understood, plastering external corners is simple; all that remains is to consider the process of working with internal ones, when plastering which it is important to follow the technology, as well as competently work with beacons, which are somewhat more difficult to install in such situations.

Plastering internal corners

People wondering how to properly plaster corners most often assumed that the concept of “plastering wall corners” meant internal corners. You will need to purchase all modern tools, without which you will not be able to do everything correctly and accurately. Here is a list of these tools:

• Long length rule. This tool was also mentioned when analyzing the previous situation; it is required to level the area located between the beacons.
• Average rule. This tool performs the same function, but only in small areas. This length rule will also help remove excess plaster.
• Angled spatula. As for this instrument, all people are familiar with it, even those who have nothing to do with construction industry. It is a right angle, which can be used to level plaster in hard-to-reach places.
• Level. This tool helps builders identify various slopes and irregularities; it should have a relatively large length (two meters is most often enough), and it is necessary for the purpose of aligning the beacons along the length. A short level, of course, could take on similar functions, but the process of performing the work will become noticeably more complicated, and beginners may even have serious problems.
• Square (90 degrees). You may need such a device when installing beacons; it will help install them strictly perpendicularly.

Note! A building level is a tool when working with which maximum accuracy is important. For this reason, it must be checked in advance for the presence of even the slightest errors, because they can significantly worsen the entire final result. To check, simply attach a level to the wall and then draw a line. The essence of the test is to flip the corner (it should also show that the line is drawn straight). Otherwise, you should purchase a new level.

Plastering process

Most likely, you are interested in exactly how to plaster a corner. In fact, everything starts the same as in the previous version. It’s enough to just start with installing and securely fixing the beacons. Pin them on plaster mortar, using a level for this. Maintain a step size of approximately 0.2 meters. Please pay Special attention for the installation of extreme beacons: they should be 5 cm away from the wall, but the most important thing is strict perpendicularity to the wall.

After securely fixing the beacons, let them dry, because you will always have time to arrive at the final result - a plastered corner. The beacons must set before you begin to apply the first coat. It is important to constantly monitor excess mixture and remove it promptly.

The unevenness remaining in the corner must be overcome using the corner staple, which was discussed earlier. Be especially careful during final leveling. Don't forget to also sand the walls; sandpaper will be useful for this.

Plastering corners, their diagnosis and leveling methods, preparation for work and processing technologies various types wall joints.

Plastering the corners is a stage of preparing the walls to a smooth state for their further decoration. It is quite complex, because it involves working with surfaces located in different planes. However, this procedure is mandatory, since crooked corners can cause defects exterior finishing and cause complications when installing furniture or equipment. Having skills in construction, you can level the corners of walls with plaster yourself.

Measuring wall angles and how to align them

In order to measure angle deviations from the vertical and horizontal, you will need a square, plumb line or building level, flat piece aluminum profile at least 2 meters long and a ruler.

To determine the depressions and protrusions, you need to attach a piece of the profile to the corner. Then you need to install it in a vertical position, which is checked building level. After performing these steps, you should use a ruler to measure the maximum deviation of the angular line from the vertical of the installed profile - this will be the desired misalignment.

The horizontal deviation of the angle from 90 degrees can be measured with a large square. It should have long sides - almost from one wall to the other. You can make such a tool using the property of the Egyptian triangle and two long rules.

In the Egyptian triangle the presence right angle determined automatically by the aspect ratio - 3:4:5. Therefore, such a figure can be drawn on the floor, and then two rules can be aligned along its sides and fastened together in the form of a right angle. This tool may be useful for further work: beacons under plaster are installed on one wall using the usual method, and on an adjacent plane using a square.

The rectangular shape of the room can be checked in another way. To do this, measure the diagonals of the room. They should be the same.

If it turns out that after checking the walls have significant unevenness, forming angles that do not meet the norm, they can be leveled using plasterboard sheets that are attached to a frame that can correct any curvature, even half a meter. However, such technology will take away a certain part of the living space, which owners usually treat very carefully.

In case of small defects in the walls, the corners are leveled with plaster, while effective area premises are preserved as much as possible. This method is more labor-intensive and involves a rather dirty process, but is highly reliable, creating a monolithic coating.

Preparing wall corners before plastering

To perform high-quality leveling plaster on corners, you should have necessary tools, prepare the wall surface and know certain rules work. Now let's talk about all this in order.

Ideal material To level corners and walls, use gypsum-based plaster. It allows you to increase the thickness of the coating gradually by applying thin layers of the mixture to the surface. Due to the rapid polymerization of the material, the plastering process does not take longer. long term.

To work with such a mixture, you need to select the appropriate tools:

• Rule. They use a rigid aluminum rail 10-12 cm wide and at least one and a half meters long. It allows you to accurately assess the condition of the plaster layer: its texture, bumps and depressions.
• Poluterok. Is it wood, steel or polyurethane board 500-700 mm long with a handle attached perpendicularly to its non-working surface. The tool is used to apply and level the plaster mortar.
• Grater. This is also a blade equipped with a handle, its length is 20 cm. The tool is used for grinding and grouting the surface. On graters used for finishing, the working surface of the canvas is covered with felt, rubber or foam rubber.
• Corner. A device in the shape of a right triangle. It is used as a measuring tool, a template when applying plaster and drawing mortar, performing the functions of a rule. To capture maximum area corner walls The size of the tool must be large enough.
• Trowel, spatula. These are a type of metal spatula equipped with a handle. A trowel is necessary for applying gypsum plaster to walls. This process involves using a triangular shaped spatula as it is most convenient. For a small amount of work, the trowel can be replaced with a spatula.

In addition to the above tools, to prepare the plaster mixture you will need a container and electric drill with a mixer attachment for mixing the solution.

Before plastering an even corner of the wall, its surface should be cleaned of old peeling coating, paint, cladding, wallpaper and other finishing. In addition, you should pay attention to the presence of grease, bitumen or salt stains. If they are present, they must also be removed by available means.

After this, it is necessary to measure the deviation of the angle in two planes in the manner described above and check the surface of its adjacent walls using a rule or an even metal profile at least 2 m long. The longer the instrument, the more accurate the measurement result. Identified lumps should be knocked down with a chisel, and large depressions should be sealed with a solution and wait for it to dry completely. Then the surface of the walls adjacent to the corner must be treated with a primer to reduce its hygroscopicity and remove dust.

Basic rules for plastering wall corners

Before starting this work, you should familiarize yourself with some rules, knowledge of which will allow you to successfully complete it:

1. The plaster can be applied to concrete, cement-sand, brick and plaster surface walls The adhesion of the mortar to the wooden base will not work without the use of sheathing made of slats or mounting mesh.
2. The thickness of the plaster layer on the walls is allowed to be no more than 50 mm, for individual recesses - 70 mm.
3. The mixture is prepared according to the manufacturer's instructions. It indicates the ratio of water and dry powder, which must be observed when mixing the solution. A small amount of added liquid will result in insufficient plasticity of the mixture, make it difficult to work with and can cause cracks on the surface of the plaster after it dries. Too much water in the solution will not allow it to gain the required strength and properly fill the recesses on the walls. Process water use is not recommended: it should not contain foreign impurities.
4. After mixing, the solution must be worked out within half an hour. Therefore, it is necessary to prepare it in small portions. You should not try to “revive” the drying mixture with water, other than deteriorating the quality of the plaster, this will lead to nothing.
5. The deviation of the corner line when plastering it should not be more than 1 mm, this will spoil the appearance of the future finish.
6. The angle between adjacent walls must be straight and strictly 90 degrees. Violation of this rule will entail problems in laying the rotating elements of pipes, joining skirting boards and installing furniture.

After preparing the walls, you can begin leveling plaster on their external and internal corners.

Plastering internal wall corners

In case of significant defects in the surfaces, the corners of the walls are plastered along the beacons, and minor unevenness at the joints is corrected using a special corner profile equipped with a reinforcing mesh - a counter-shoulder.

Plastering wall corners along beacons

This method of plastering corners is used when leveling walls around the entire perimeter of the room. To work, you will need a large square, the manufacture of which was mentioned above.

First of all, you need to select a supporting wall, mark the location of the beacons on it and fasten the screws according to it. By placing their caps at the same level, a base plane is formed. This procedure is performed using a plumb line.

The next step is to position the bottom and top screws away from the supporting wall. In fact, to obtain a right angle, it is enough to correctly install the nearest bottom screw. First, it should be screwed into the dowel as much as possible, taking into account the gap for the beacon of at least 6 mm.

After this, you need to attach the square to the pair of lower screws of the supporting wall and the far screw on the adjacent plane. It is necessary to determine what to do with the screw closest to the corner. If the rule of the square does not touch its head, the screw must be unscrewed until it touches. If the rule rests on the near screw, but does not touch the far beacon, you should unscrew the far screw. As a result, the heads of the four lower screws located on different walls, should create a right angle.

The upper screws are already leveled, focusing on the height of the lower screws being unscrewed from the wall. After installing the lower and upper screws on both walls, you need to check the thickness of the plaster layer under the beacons. After the beacons have hardened, their location can be checked again with a square. The step between beacons should not be less than the length of the rule.

The solution is applied first on one side of the corner. The cavity between the beacons is filled with the mixture and then distributed according to the rule. After one wall of the corner has dried, you can move on to the adjacent wall.

To smooth the joint of the walls, a special angled spatula is used, which greatly facilitates the work. Hand movements should be directed from the corner. During operation, the tool must be periodically moistened with water.

Plastering wall corners using a counter-shultz

This method is good if the walls are already leveled and you only need to finish the corners. To perform this work, you need to cut off a piece of corner with metal scissors reinforced mesh. Its length should be equal height corner. Aluminum contra-shultz is quite soft, for this reason special effort You should not apply it to it, so as not to disturb its shape.

Then apply a little gypsum mixture to the joint of the walls using a spatula and distribute it along the height of the corner. A piece of the counter-shoulder must be applied to the corner and, using long rule press it down lightly. The work should be done carefully, since the metal of the corner is quite thin and easily deformed.

Excess plaster mixture will be squeezed out through the profile perforations. This solution must be transferred with a spatula onto the counter-sharp mesh, smoothing it.

When the mixture has dried, the surface of the corner should be sanded with a fine-mesh abrasive mesh. If the surface is being prepared for painting, you need to apply a thin layer of fine-grained gypsum plaster to it, level it and rub it in after drying.

Plastering wall corners with reinforcing tape

With the help of plaster, an even angle of the walls can be achieved using a wide reinforcing serpyanka tape. This method is used only to form a joint between surfaces at an angle of 90 degrees and does not provide for their complete alignment.

To work you will need gypsum plaster, wooden block strictly rectangular section and 40-60 cm long, as well as reinforcing tape.

A small amount of plaster should be applied to the joint line of the walls, covering 10 cm from each adjacent surface. Then the edge of the serpyanka needs to be applied to the top of the corner and, holding it at this point, unwind the roll to the bottom, as far as the width of the arms allows. When performing this procedure, it is important that the serpyanka does not deviate from the given direction and evenly covers the joint.

After gluing the tape with plaster, you should take a block, and then, using pressing movements along the joint line and its planes, give the corner a straight shape. The crumpled tape on the walls can be leveled with a spatula, and the excess mortar can be transferred to the rest of the area, distributing it from the corner line. You need to work with a spatula carefully so as not to disturb the position of the tape at the joint. After the mixture has dried, the reinforced coating of the corner should be sanded with an abrasive mesh or sandpaper.

Plastering external corners of walls

Beautiful, ideally shaped external corners can be achieved with or without a perforated metal profile. In the first case, the strength of the corner will be higher.

Plastering the external corner of the wall without reinforcement

Before starting to work with this method, all protrusions on the wall surfaces adjacent to the corner should be knocked off with a chisel and large cracks should be sealed with mortar. The process begins with installing a flat board or wide strip on the side of the corner, which will serve as a kind of formwork. Fastening is done to the floor and ceiling, but if you choose the optimal length of the board, it can be installed by surprise.

The board should be wrapped with tape and protrude from the outside around the corner to a distance equal to the thickness of the plaster layer. The adhesive tape is designed to prevent the solution from sticking to the surface of the “formwork”.

Then plaster is applied to the surface adjacent to the corner and distributed over the entire height of the joint using a rule. Movements are made towards the corner with a slight downward inclination.

After no less than two days, you need to carefully dismantle the board and attach it in the same way to the already plastered side of the corner. Then you should repeat the above procedure with the other wall.

The finished corner is sanded with sandpaper or a grater equipped with an abrasive fine mesh.

Plastering the external corner of the wall with a profile

The metal profile forms a straight line of the corner and protects it from accidental mechanical damage. Calculating the number of aluminum corners is not difficult: you need to measure and sum up the lengths of all external wall joints and add 10% to the resulting figure, taking into account material waste during installation. Standard length the corner is 3 m, and the height of the premises is from 2.5 to 2.8 m. Thus, 20–50 cm of the profile in the form of trimmings for each corner will be wasted. They can be useful for forming short corners on wall or ceiling projections.

To form a right angle when plastering walls on its adjacent surfaces, you first need to apply the prepared gypsum mixture.

A corner of the required length is attached using pressing movements to the area treated along the entire height of the joint. It is advisable to carry out this work using a rule that will prevent deformation of the corner from careless hand pressing.

Excess mixture squeezed out through the perforation of the profile is transferred with a spatula from its metal part to the mesh. Immediately after installing the corner, its position on the wall should be checked with a building level. While the mixture has not hardened, any adjustment is possible.

After the plaster has dried, the corner of the wall should be sanded with an abrasive material. The finishing of the corner is carried out in conjunction with the walls.

Plastering rounded corners of walls

It is not difficult to plaster rounded corners of walls. First, adjacent joint surfaces of enclosing structures should be leveled with a gypsum mixture using standard technology. When creating curves, the planes of adjacent walls act as beacons, and the rules are a special template.

It can be made like this: a strong plastic wire needs to be pressed into a rounded corner, the shape it acquires will give the outline of the future template. Then the sample must be attached to thick plywood and outlined with a pencil. Along the resulting line, you need to trim off the excess material. The template is ready.

Then you should throw a plaster solution over the corner along its entire height and remove its excess with a template. Ellipses small sizes do not require reinforcement. But when making curves with a diameter of more than 100 mm, they need to be strengthened with wire or reinforcing mesh. You can get by using screws. They are screwed into the curve with a pitch of at least 200 mm.

After the corner plaster has dried, you need to apply the final finishing layer with the addition of fine sand to the solution. This coating is rubbed with felt to create the maximum smooth surface rounded corner. Grouting should be done only with horizontal movements.

How to plaster the corner of a wall - watch the video:

Plastering and leveling corners is considered the most difficult task, especially for beginners. It requires quite a high level of professionalism. However, with a conscientious and leisurely approach to this matter, you can create even corners in the room quite independently. The difference when the work is performed by professionals lies in this case only in the time that will be spent on it.

How to make even corners when plastering walls, internal and external?

Furniture manufacturers always carefully measure it rectangular shape, but in apartments sometimes the geometry of the room turns out to be incorrect, and you need to decide how to make even corners when plastering. After all, it’s unlikely that anyone needs problems when arranging the interior when wardrobe, made taking into account the presence of baseboards, does not fit into a narrowing corner, or, conversely, huge gaps remain between the furniture and the walls. Therefore, let’s deal with practical stereometry, that is, working with a three-dimensional figure, which, in fact, is the room.

1. How to make even corners when plastering if the curvature is small?
2. Aligning external corners with a large error
3. Plastering internal corners, setting geometry with laser

1 How to make even corners when plastering if the curvature is small?

Most often, owners of houses and apartments are faced with the problem of fairly crumbled external corners that have lost their shape, at the turns of corridors, in niches and alcoves, on vertical beams(reinforced concrete crossbars). It’s quite simple to check how big the error is; just take a regular metric square and place it on the converging surfaces of the walls. If there is curvature, either one scale will not touch the wall, or, conversely, both will touch, and at the junction of the walls there will be a gap between them and the measuring instrument. In other words, our external angle is acute or obtuse, respectively.

If the deviation from the correct geometry is small, up to 2-3 millimeters, to correct it it will be enough to use a counter-shultz (perforated corner overlay) and a putty mixture. With a very small error (up to 1 millimeter), one putty is enough. Before making even corners when plastering walls, a primer is always used, the same applies to other finishing materials.

After priming, generously cover the entire vertical joint of the walls with the mixture and apply the perforated part so that part of the leveling compound appears through the holes. Next, use a regular spatula to smooth out the visible finishing material so that the counter-shultz disappears almost completely under it. From the corner, use the same putty to level the entire wall using the rule.

2 Alignment of external corners with a large error

If the situation is much more serious than we would like, we will need a three-line laser level, which we will use to level the wall, as well as a couple of old two-meter rules and a plaster mixture. It is advisable that the beam level be supplied with a tripod, with which it will be possible to place marks on different heights. We will also use the counter-shultz, but as a fastening element, to increase the reliability and durability of the corner, so we take a perforated overlay with wider shelves or with a mesh. Now regarding the finishing itself.

How to align external corners when plastering - step-by-step diagram

Step 1: Making the fixture

Using lasers, between which the angle is exactly 90 degrees, we make a two-meter square from the rules, folding their ends overlapping so that the rays pass exactly along the inner edges along the entire length up to the far ends. We screw in three self-tapping screws at the connection point. Such a device for checking the geometry in the layout is only suitable if both walls are longer than two meters. If one of them is significantly shorter than the rule, we either saw off the excess part of one of the sides of the square, or do not make it at all, but use exclusively a laser, which is more difficult, but no less effective.

Step 2: Setting up beacons

If the walls, the convergence of which needs to be set at 90 degrees, are longer than two meters, we rest the laser beams on their far ends and along the luminous lines with self-tapping screws (twisting them desired depth) we place beacons under the far ends of the connected rules. Next, we screw the screws into the holes specially made for them at equal intervals along the square, first on the same plane, then we rise a meter and a half higher. We try to drill holes at different levels, one above the other, for which it will also be useful laser level.

Step 3: Installing beacon profiles

So, we have self-tapping screws screwed in even rows along the entire wall and secured with either gypsum plaster or putty. Now we need to make sure that they are all at the same level, for which we resort to a laser, installing it at the lower corner screw on the plane of its head. All other screws should also light up, those that are slightly lower, we unscrew, and those that go beyond the line, we screw in. Using self-tapping screws, we vertically attach beacon profiles with a thickness of 6 millimeters using gypsum plaster mortar. To do this, apply the solution in vertical stripes along the screws, put profiles on it and press it along the entire length with a rule until it touches the screws and lies on them. We remove the excess mixture, being careful not to touch the lighthouse.

Step 4: Forming the Outer Corner

Then you can apply the primer, and when it dries, apply the plaster. In general, this primer layer should be the second; the walls should be coated first after placing the screws in one plane, having previously cleaned off the excess mixture that fixes them. The plaster mixture is applied in a layer of about 3 centimeters, compacted along the beacon profiles using the rule (for this we disassemble our device). When both walls are ready and we reach their connection, we put the two rules together again and with their help, sketching out the mixture, we form a corner. Next, apply the contra-shultz with the mesh, lightly pressing it into the mixture, which we spread on top. The second layer should lie on top after the first has dried.

Between each layer finishing material It is advisable to apply a primer even before laying the top coat. It follows from this that you should wait for each layer to dry completely.

3 Plastering internal corners, setting geometry with laser

The error in the degree of internal closure of the walls is somewhat more difficult to determine, since it will no longer be possible to use a laser level; the housing will interfere. Therefore, we still use our same giant two-meter goniometer, but first we still take a level and with its help we prepare the “starting” supporting wall, that is, the one in relation to which we will set the second plane. To do this, you will need a three-line level, whose rays diverge 180 degrees from the body installed in the center of the wall.

How to plaster internal corners - step-by-step diagram

Step 1: Beacons on the supporting wall

First, we screw in the laser screws along the floor. Then we move to a higher level, fixing the screws exactly above the lower ones. So we move upward, exposing the plane with beacons, which should eventually line the vertical surface into even squares with sides of about 1 meter.

Step 2: Installing beacons on an adjacent wall

First, we screw in only one self-tapping screw, at the level of the far end of our large square, the second strip of which already lies evenly on the row of screws of the “starting” surface. Then, exactly along the edge of the rule, we install the second beacon, the closest one, adjusting its height with a screwdriver. We do the same with the rest, adjusting them using a laser directed along the entire wall and a protractor until the second wall is covered with rows of screws.

How to plaster corners? The video helps a lot, but still this question, which is asked not only by beginners, but also by those who have already faced the renovation of their rooms, requires written explanation.

Well, let's try to create detailed instructions together.

What tools will you need?

Be sure to buy a rule, one level, a trowel with rounded edges near the handle, spatulas (one narrow and the other wide), and a trowel. For the plaster mixture, purchase a grater with a rubber sponge, and for your corners, a leveler and a trowel.

You can’t plaster a corner well without beacons, so buy beacons and their fasteners, a hammer drill and dowels.

For external profiles you will have to fork out for galvanized corner profiles.

Installation of galvanized profiles

Their installation technology is no different from that when you attach beacons to Rotband plaster.

For corners, also buy it and apply it in blobs along the entire height of the wall (corner).

Insert the corner profile into the gypsum mixture, pressing lightly.

Take the rule with a peephole and vertically align the mixture along the plane of one and the other wall so that a beautiful outer corner is formed, while removing the excess of the prepared solution. Once the corner has frozen, you can begin plastering work.

How to plaster corners: video to help

This story will definitely interest you.

Have you watched a short film?

Let's get down to theory. Look at your walls: if they converge at the outer corner without flaws, then you can throw mortar on them and use the rule: do not forget to press it to the beacons and at the corner profile. If you set both the beacons and the profile correctly, then your angles will turn out just perfect.

What to do when on some segment there are two internal angles, but only one external?

Here you yourself must determine which of them immediately catch your eye. They need to be plastered at 90 degrees. The rest - no difference.

Plastering walls along beacons, leveling planes and corners

But builders still advise making the internal ones straight, since the external one does not visually concentrate attention as much.

Start by installing the profile on the outer corner and only then take hold of the beacons. Moreover, align them strictly vertically. A plaster square will help you: use it to ensure that your beacon and the plaster plane are at an angle of 90 degrees to the finished wall.

If the square is small in size, then lengthen it by attaching it to the rule.

You won't need beacons in interior corners. Now you can apply the solution to the wall: whether you want it manually or using a machine.

The main thing is to align the two walls so that the internal corners are pleased with the correct geometric proportion.

It is difficult to find a perfectly straight wall in the house, and even more so its corners. When performing external and internal work, you cannot do without their alignment. Plastering the surface yourself and leveling the corners yourself is not so easy, but it is possible.

You just need to find out what problems may arise and how to deal with all these difficulties.

So, how to plaster the corners of walls. If you absolutely cannot do without this procedure, then the first thing you need to pay attention to is to decide exactly how the work will be carried out, in what way - on a plane or on a level.

For example, if you plan to glue wallpaper in the future, then such leveling will need to be done only with the help of a level, and if you plan to paint, then the work should be done on a plane.

That’s why decide right away and think through everything before doing the finishing work.

What materials and tools will be needed?

If you do not have the opportunity to hire specialists and want to act independently, then it is better to give preference starting putty or plaster.

It is much easier to work with, and it allows you to level the base with a fairly thin layer without having to worry about it sagging.

You also definitely need to purchase a primer to prepare and treat the wall.

In addition, you will need a number of construction tools, to complete all work:

• Spatula of suitable sizes;
• Container for solution;
• Level and rule;
• Drill with tip;
• Manual sprayer;
• Sandpaper;
• Grater.

Correct selection of plaster mixture

At the moment, the most popular and popular mixtures are cement and gypsum based mortar.

For example, gypsum mixture is in demand for the following reasons:

• Thanks to it, up to five centimeters can be applied to the surface, and at the same time cracks will not appear from the large thickness;
• This solution does not shrink quickly, unlike others;
• Gypsum is famous for its high ductility;
• Also, this mixture is light in weight and has high adhesion, so it can easily level any surface, even the ceiling;
• The presence of a good thermal and sound insulation system allows the base of the surface to breathe;
• Thanks to this base, the plaster allows you to carry out work without reinforcing mesh, even on a smooth concrete wall.

How to trim internal corners?

First, you should apply the rule to the wall and evaluate all the irregularities.

This tool should be placed clearly along the edge and all protrusions and notches should be marked with a pencil at once.

Simple tips on how to level a wall corner with your own hands at 90 degrees

There are, of course, bumps that can be seen even with the naked eye; they need to be knocked down or cut down.

There is no need to spare primers; the more, the better the result.

Now you should start next stage– installation of beacons.

Lighthouses look like a plaster track about five centimeters wide. In order for the beacon to lay down clearly, there should be no lumps of solution on it; for this, the mixture should be thoroughly broken up and stirred with a mixer or drill with a special attachment.

The lighthouse must be leveled.

Corner alignment technology

How to plaster the corners of walls? The answer is simple: using a spatula and starting mixture. The mixture is applied along the entire length of the rule and tightened.

To do this, one end of this tool should be rested on the lighthouse, and the other on the wall.

This process should be done until the gap under the rule disappears, which means that the angle is absolutely even.

However, do not rush to apply many layers at once, otherwise everything will simply fall away. You need to wait until the first layer dries and sets stronger, and only then do the next one. To ensure that the solution adheres well, use a spray bottle to moisten the surface with water, especially in very hot weather.

Plastering external corners

This work is done in several ways:

• For initial plastering, metal beacons or profiles should be installed;
• To re-layer, you should already take a special strip.

With metal or plastic profiles It’s easy to work with and without much difficulty you can get perfectly even corners on the outside of the building.

The profiles are easy to cut with wire cutters, so they can be shortened if necessary.

As always, it is important to prime the base, then apply a thin layer of plaster and, pressing a little, attach the profile to the joint of the wall. All excess solution should be removed and the surface should be checked and leveled using a level.

When the profile hardens and holds firmly, then the next layer of composition is placed on it to completely cover it and achieve evenness.

Special wooden slats fixed on one side of the corner on an alabaster mortar in a vertical position.

It is important to ensure that the rail protrudes by a thickness of 5 millimeters. Leveling is carried out with a grater, and once everything is dry, the lath must be completely removed. We do the same on the other side of the rib.

The final stage is grouting

To complete this process as quickly and efficiently as possible, you should wait until the solution dries completely.

If you rush and grout while it’s wet, you can damage or scratch the already completed base. Grouting is done inside with sandpaper, and outside with a trowel.

Before using the trowel, wet it and apply the solution thinly, and then at an angle of 45 degrees. Rub the surface with strong pressure. Continue the process until excess accumulates on the ironing board.

In the end you should get even and smooth corners.

Watch the video:

Since plastering the corners of the walls is very important for the correct geometry of the entire room, and will ensure the quality of all other finishing work, be sure to strictly follow all the technology or ask for help from specialists who carry out this finishing.

The exterior beauty of your home depends entirely on the job being done correctly.

Aligning the corners is the final stage finishing walls before their subsequent finishing wallpaper or painting.

It is not surprising that it is the most difficult, since making a 90° evenness is quite difficult.

Aligning the corners of walls requires some skill, especially for amateurs who try to do everything themselves.

Do we need 90°?

The question is rhetorical, since most apartment owners who are trying to achieve the geometric accuracy of all their corners with their own hands do not understand why this is even necessary, as in that saying: “So that it is.”

But why, if you plan to decorate the walls with carpets and paintings the old fashioned way?

Perfect evenness of the corners is important if you plan to install modern stylish furniture or household appliances in them. In such cases, deviations will be noticeable to the naked eye, which, you see, is not very beautiful. If visually they seem straight, and a carpet hangs nearby, then no one will notice a deviation of a couple of degrees. However, leveling the corners of the walls is an important task when carrying out European-quality renovations in an apartment.

How will we level it?

There are two ways to solve the problem - using dry plaster or drywall and using wet plaster.

What are the advantages of each?

1. Plasterboard sheets have an almost perfectly flat surface.

   With their help, you can level even walls that are completely “insane” along the curvature with your own hands. They are mounted on a frame that can hide irregularities of at least 10 centimeters, at least half a meter. The installation itself will not take much time, but then you will have to carefully putty all the joints and, interestingly, level the corners. But doing this on a flat surface is much easier.

2. Wet plaster.

   A familiar and familiar way to everyone. There is always a lot of dirt from him, physically such work is also difficult. However, this method is perfect if the height difference on your walls is not too great. Therefore, if we level the corners of the walls with plaster, then we will be able to preserve such important square centimeters of the area of ​​​​our home for all of us.

Step-by-step instructions for leveling corners with regular plaster

This method can be used if the deviation at a distance of two meters does not exceed a few centimeters.

If it is larger, then you will have to work in several stages, which is completely impractical, since it is faster and cheaper to level the walls with plasterboard.

Now, in order.

1. We will completely clean the walls of the old coating with our own hands, this is always better than cleaning in pieces, and we will walk along the wall with a level or make plumb lines and pull the thread.
2. If the curvature of the walls has not changed after cleaning, we will prepare a cement mortar for work.
3. Using a roller, prime the surface and let it dry.
4. To properly level the walls with your own hands, you need to set up beacons.
5. After installing the beacons, you can spray.

   As a rule, remove the excess and throw it into a bucket of solution.

6. Let the layer dry and prime again.
7. Let's apply another leveling layer.

   Often two layers are enough for quality leveling. Let's smooth it out, let it dry a little and rub it in.

8. If the walls are made smoothly, then the corner appears by itself; no special work is required to bring it into proper shape.
9. For convenience, you can use a counter-shultz - an internal corner, the same as for aligning external corners, with a reinforced mesh along the edges.

   In this case, first we “plant” it on thick putty, press it into it and remove the excess with a spatula. Then you can start leveling the walls with regular plaster.

Step-by-step instructions for aligning internal corners with drywall

In the case of drywall, everything is much simpler.

1. To level the internal corners of such walls, it is enough to putty the corners with high quality, you can use counter-shultz, but, as a rule, ordinary serpyanka, which is glued to the internal corner, is sufficient.
2. Cover with putty from one wall, then from the other wall.
3. Then they run it over it with an angled spatula and check their work with a level.

Aligning outside corners

This is not the most time-consuming process.

Take a special corner, even better if it has a reinforced mesh around the edges. It can be attached to the wall using self-tapping screws, and then carefully covered with plaster, or it can be placed on the plaster, additionally secured with self-tapping screws.

In the first case, everything is clear. In the second, we apply plaster mortar to the wall on both edges of the corner, carefully apply the corner and recess it into the mortar.

We fix it with self-tapping screws for reliability and press the mesh into the plaster. Next, smear the protruding solution with movements from below/to the right and from below/to the left. You can add a little solution to completely cover the mesh and corner.

On a note. To align wall corners, choose aluminum corners. Firstly, they do not rust, and secondly, they are very flexible and convenient to work with. And don't forget to use a level to install them. This scheme of work is applicable for both ordinary plaster, and for forming an outer corner after leveling the walls with plasterboard.

Only in the latter case is the corner mounted on the putty mixture.

Aligning interior corners is a more difficult task for the amateur or novice. Filigree precision is required here, otherwise all the work will be in vain.

Briefly, the order of work is as follows. One wall is leveled with plaster, checked for level, then the second.

Ideally, if no miscalculations were made at the leveling stage, the angle should be 90°.

To get an idea of ​​the process, watch the video on aligning wall corners. A visual aid never hurts.

It is worth noting that when working with ready-made corners, although we get an almost perfect internal or external corner, it will never be sharp, rather slightly rounded.

This is due to the geometry of the aluminum profile.

Therefore, as one of the options for removing the outer corner, you can use two spatulas placed at right angles to each other. The work is carried out somewhat “by eye”, but the result is not bad. Plus, do not forget that after removing the corner with plaster, you also need to putty them. These works will allow you to finish off what didn’t work out when working with the plaster mortar.

Now you know how to align the corners of the walls. In any case, it must be remembered that knowledge of certain points does not exempt you from making mistakes. Therefore, if finances allow, it is better to seek help from professionals.

This will help you avoid annoying mistakes and waste your time.

If you decide to do everything yourself, do not forget to also pay attention to the plaster mixture you will be working with.

Aligning corners - step-by-step instructions for beginners (75 photos)

If in the kitchen and bathroom it is best to work with cement compounds, which must be puttied after drying, then in dry rooms with a smooth surface temperature conditions It is better to use gypsum. Firstly, they do not require puttying, and secondly, it is easier to remove the corner with them.

Finally, watch the video on aligning interior wall corners. Perhaps this will help you in choosing whether to work with your own hands or turn to the craftsmen.

Other materials on the topic:

Angular alignment is last phase covering the wall before the next finish with wallpaper or painting. Unsurprisingly, this is more difficult since achieving 90° balance is quite difficult.

To balance the corners of the walls, it requires some knowledge, especially for amateurs who try to do everything themselves.

Do we need 90°?

Rhetorical question, since most apartment owners are trying to get the geometric precision of their hands in all corners, I don’t understand why it’s even necessary to make a river: “For me.”

But why if you plan to decorate the walls with carpets and paintings?

Perfect corner uniformity is fundamental if you intend to install a modern elegant furniture or household appliances. In such cases, the refusal will be visible to the naked eye, which you will agree is not very pleasant. If they appear visually straight and the rug is hanging, then there will be a deviation of a few degrees that no one will notice.

However, aligning the corners of the walls is an important task when renovating an apartment.

Then we'll be level

The problem can be solved in two ways - with dry plaster or drywall and with wet plaster.

What are the advantages of each?

1. Drywall has an almost completely flat surface.

   With their help, you can measure even completely “irresponsible” wall curvature with your own hands. They are mounted on a frame that can hide irregularities of at least 10 centimeters by at least half a meter. The installation itself does not take much time, then you must completely block all the connections and, of course, align the corners. But doing this on a flat surface is much easier.

2. Wet plaster. Everyone is known and known. There is always a lot of dirt from it, but physically this work is also difficult.

   However, this method is ideal if the height difference on the walls is not too high. So, if we plaster the wall, then we can save the square centimeters of our area that are important to all of us.

Step by step for leveling corners with regular plaster

This method can be used if the deviation at a distance of two meters does not exceed a few centimeters.

If there are more of them, then it will be necessary to work in several stages, which is very impractical, since it is faster and cheaper to raise plasterboard walls.

Now, okay.

1. Clean the wall with your hands on the old coating completely, this is always better than cleaning parts, and go through the wall with a level or make sections and pull the thread.
2. If after cleaning the curvature of the walls does not change, we will prepare a cement mortar for work.
3. With a roller we will pop the surface and let it dry.
4. To properly level the walls with your own hands, you need to install beacons.
5. After installing the beacon, you can spray.

   The rule is to remove the excess and throw it into the solution bucket.

6. Let the layer dry again and reheat.
7. We will use another alignment layer. Often two layers are enough to equalize the quality. We smooth it out, wipe it down a little and compress it.
8. If the walls are accurately designed, he does not need any special work as it takes care of itself to view it correctly.
9. For convenience, you can use the opposite shell - an inner corner, the same as for lining outer corners, with reinforced mesh around the edges.

   In this case, first "plant" on the thick set, press it down and remove the excess blades. Then you can level the walls with regular plaster.

Step by step for aligning interior corners with drywall

In the case of drywall, everything is much simpler.

1. To level the internal corners of these walls, it is enough to putty the corners with good quality, you can use counter-shots, but usually a smooth sickle glued to the internal corner is sufficient.
2. Cover the side of one wall with whales, then the other wall.
3. Then use an angle putty knife on it and check their working level.

Aligning outside corners

This is not the most demanding process.

Even better, it's a special angle than with reinforced mesh around the edges. You can attach it to the wall with screws that are screwed in, then carefully plaster with plaster or can be attached to the plaster, secure it with screws.

In the first case everything is clear. In the other, on the two edges of the corner, place the wet solution on the wall, carefully use the corner and heat it in the solution.

For reliability, secure with screws and press into the plaster mesh. Next, dissolve the resulting solution using bottom/right and bottom/left movements. You can add a small solution to completely cover the mesh and corner.

On a note. To align wall corners, choose aluminum corners. Firstly, they do not rust, and secondly, they are very mobile, so they are comfortable to use. And don't forget to use levels to install them.

This scheme of work is used both for regular plaster and for forming an external corner after leveling the walls with plasterboard. Only in the latter case is it a corner set on a coffee mixture.

Aligning interior corners

Aligning interior corners is more difficult for amateur or journalistic work. This requires filigree precision, otherwise the whole work will be awkward.

In short, the order of work is as follows.

The plaster is leveled with one wall, checked with a level, and then the other. Ideally, if there are no errors during the alignment phase, it should be 90°.

To learn about the process, see the Video on Aligning Wall Corners.

Visible help never hurts.

It should be noted that working with closed corners, although we get an almost perfect inner or outer corner, it will never be sharp, rather rounded.

This is due to the geometry of the aluminum profile.

Therefore, as one of the options for removing the outer corner, you can use two blades that are positioned correctly. The work is done in some way “by sight”, but the result is not bad.

Plus, remember that after removing the corner of the plaster, they need to be plastered. These works will allow you to complete what does not work with the plaster mortar.

Recruitment tips are available here.

Now you know how to straighten the corners of the walls. In any case, it should be noted that knowledge of certain points is not exempt from errors.

How to finish the outer corners of Rotband drywall?

Therefore, if financial means allow, it is better to apply for professional help. By doing this, you will avoid hard mistakes and you will not waste time.

If you decide to do it yourself, be sure to take into account the mixture of plaster you'll be working with.

If the kitchen and bathroom are best done using cementitious compositions, which are absolutely necessary after drying the pots, it is better to use plaster in dry areas with flat temperature conditions.

Firstly, do not require putty, and secondly, it is easier to show your own.

Finally, watch a video on lining up interior wall corners. This can help you decide whether to do it yourself or contact a professional.

Other materials

When carrying out rough finishing works, the question arises of how to plaster the corners of the walls. These areas are quite difficult to process. Therefore, the technology and premises of the building have its own nuances and characteristics.

First of all, it is necessary to carefully prepare the surface of the walls. During the work itself, the main condition for its quality is the creation of an absolutely even corner joint.

Some points to consider

Before you draw out the corners when plastering, you should take into account that there are two methods for aligning them.

The use of these methods depends on the subsequent .

1. If it is ceramic, porcelain stoneware, clinker tiles, or wallpaper with an abutting pattern, then the corners must be aligned exactly to the level.
2. When the walls are painted, covered with wallpaper without a pattern, or covered decorative plaster, then the corners can be aligned only along the plane.

Before work, you need to select a type of plaster mixture, calculate the approximate consumption and purchase it.

1. If you plan to decorate the walls outside the house or wet rooms inside it, then the work should be carried out using cement, lime, or polymer plaster.
2. In dry rooms, in addition to the above types of solutions, gypsum-based analogues can also be used. The instructions do not recommend using them in damp rooms, since the material does not have sufficient moisture resistance.

Note! Buy plaster mixtures, produced only well-known manufacturers. Even if their price is a little higher, you will be sure of the quality of the work. Before plastering, treat the corners with your own hands with deep penetration primer. It will significantly improve the adhesion of the finish and the base.

Plastering works

To finish the corners you will need the following:

• plastic container for solution;
• bubble level and plumb line;
• aluminum rule;
• large, medium and small spatulas;
• foam or wooden grater;
• electric drill with a nozzle for stirring the solution;
• emery cloth various sizes graininess.

Processing internal corners

1. Before plastering the corners, check their evenness using a plumb line or level. If they have very protruding tubercles, knock them off with a chisel and hammer. This will make your main work easier and save plaster mixture.
2. After the surface is prepared, it needs to be primed. This treatment will strengthen the corners and improve the adhesion of the plaster to the wall. The surface must be primed for the entire length of the rule used.

1. On the question of how to make even corners when plastering. The control guides (beacons) will make your work much easier. They need to be done right in the corner.
2. When the primer is dry, you can begin installing the beacon. It should be a strip of gypsum mortar, having a width of 4/5 centimeters. The mixture must be mixed well before application so that there are no lumps left in it.
3. The finished solution is applied in the form of a strip to one of the adjacent sides of the corner from top to bottom. Next, it is aligned vertically using a rule and a level.
4. After grasping the first beacon, in the same way you need to install another control guide on the opposite wall.
5. Then you can begin to level the angle itself.. First you need to throw or spread the solution over this entire section of the wall.

1. Its excess is removed using the rule. An important nuance is how to plaster internal corners correctly. To tighten the angle unnoticeably and smoothly, you need to choose a rule that is of sufficient length to support the beacons.
2. When tightening the mortar, one side of the tool should rest on the guide strip, the other, when moving vertically along the wall, should cut off excess plaster.

Note! This excess solution is not recommended to be reused, especially if it is quickly hardening gypsum plaster. Particles of the mixture that have begun to set will disrupt the homogeneity and plasticity of the material.

1. After spreading the main layer of the mixture, apply another thin layer of mortar (covering) to correct minor unevenness and grooves. Tighten it also with a rule.

1. Experts give another valuable advice on how to remove a corner with plaster. Its final alignment is most conveniently carried out using a special one.

Plastering external corners

Now about how to properly plaster the corners of external walls.

1. First of all, they are checked for evenness. If necessary, use a chisel to knock off all the ridges and protrusions.
2. Then the wall surface is primed.
3. To properly plaster external corners, it is best to use metal profiles. They are corner strips with perforations.
4. These ready-made guide beacons are attached to the corners by pressing them into the gypsum mortar previously applied to the wall.
5. Excess mortar coming out of the holes must be removed with a spatula, and then check the vertical installation of the beacon.
6. Next, plaster beacons are placed on both sides of the corner.

1. After this, the surface of the adjacent walls between the metal guide and the plaster is plastered.

Conclusion

Now you know how to align corners with plaster in the optimal way. The main thing here is accuracy and carrying out the work strictly according to the level. If something remains unclear to you, watch the video in this article.
