It will quickly lose its original appearance, and will have to again. To save time and money, it is better to immediately align the walls with high quality. What is the best way to level the walls and how to carry out all the work?

Roughness assessment of the wall surface

All methods of leveling walls are divided into two fundamentally different groups.:

One way or another choose, taking into account the degree of unevenness of the walls so this step is especially important. How uneven the walls can be measured laser level or conventional building level.

Sequence of work looks like this:

1. wall surface preparation. In order for the leveling compound to hold, the wall must be properly treated. First, all remnants of the old coating are removed, then priming is carried out for better adhesion with a layer of plaster. Under cement compositions, a mortar primer is used, and water, the so-called cement milk, it is better to use a special one for gypsum plaster;
   
2. if the plaster layer is more than 2 cm, then at this stage it is better to use reinforcing plaster mesh, which will not allow the composition to crumble. It is worth noting that if you use a ready-made factory plaster mixture, then you should pay attention to the composition: some manufacturers use polymer additives that increase the strength and degree of adhesion of the mortar so much that the mesh may not be needed;
3. installation of beacons. As beacons, which become a guideline for creating a flat surface, wooden slats or a perforated metal profile are used. The latter will be more convenient for beginners, since such beacons will not have to be removed after the plaster layer has slightly hardened and then mask the recesses. First, two beacons are mounted at opposite ends of the wall, while, and the beacons are fixed with a gypsum mortar of the required height until ideal verticality is achieved. Three cords are stretched between the two beacons received: at the top, in the middle of the wall and at the bottom, and already focusing on them, intermediate beacons are installed so that they lightly touch the cord. The step between the beacons depends on the size of the tool with which the plaster mixture will be leveled (usually a rule is used for this). In any case, the distance between the beacons should be 20 cm less than the length of the instrument;
4. 
   in a wide range can be found in hardware stores. At the construction site, it remains only to properly prepare the solution, following the instructions. Cement plaster mortar can be prepared independently: cement and sand are mixed in a ratio of 1:6, then water is added to a creamy consistency. Some experts recommend adhering to the ratio of components 1:2 or 1:3, the finished mixture is more plastic, and therefore easier to handle. The finished solution is used for 1-2 hours until it begins to solidify;
5. plastering. To do this, you can use the "falcon" and a trowel. On the first one they collect the mixture from the container, on the second they throw it on the wall in excess. The use of a “falcon”, a tool similar to a trowel, but larger than it, allows you to increase the speed of work. Now you need to evenly distribute the solution from the bottom up, relying on the beacons. If the leveling layer is thick, then you can first apply a rough outline of the plaster, and after it dries, apply the main one with alignment along the beacons. If wooden slats were used as the latter, then when the mortar dries a little, they must be carefully removed, the cavities filled with plaster and leveled with a spatula;
6. 
   after the plaster has dried, we get a smooth, but rough surface. In order to make it smooth, you need to apply thin layer of putty, and then sand the surface with fine sandpaper.

The main advantage of this leveling method is the maximum preservation of the usable area of ​​​​the room. The disadvantages are the laboriousness of the process, the need to prepare the base and the presence of a large amount of dust.

No. 2. Leveling the walls with putty

However, do not forget that this method of leveling the walls takes up a lot of usable space, and if it is already in short supply, then the room risks turning into a hole. Walls sheathed with drywall sheets will be able to withstand less load than those that have been lined with plaster. If we are talking about a room with high humidity, then moisture-resistant drywall sheets should be used.

Sequence of work:

1. 
   frame construction. It may consist of or a metal profile. The beam does not allow to achieve the desired durability of the frame, it is subject to the influence of moisture and microorganisms, therefore, in most cases today they are used guide and rack metal profile.
   The first two profiles are attached to the floor and ceiling.
   On the floor, using a level, draw a straight line at a distance of 5-6 cm from the wall (more is possible if the curvature is large or communications need to be hidden).
   Using a vertical plumb line, the line is transferred to the ceiling.
   Guide profiles are fixed along the lines obtained with self-tapping screws, constantly checking the evenness of their level with a plumb line. Between them, perpendicular to them, load-bearing profiles are attached along the wall with the help of. The distance between them is 40-60 cm for drywall sheets 120 cm wide;

Aligning walls with your own hands is not an easy process that even a beginner can handle with diligence. First you need to decide on the desired result and method of work. There are several ways to level the walls with your own hands, in each case there is an optimal option.

Types of alignment

According to the technology of work and material, dry and wet alignment are distinguished. Dry leveling is advisable to use in rooms with large surface errors, in wooden houses. Wet alignment is used for both minor deviations and noticeable ones. Let's take a closer look at how to properly align the walls for each technology.

Dry leveling

Dry leveling, also known as frame leveling, significantly saves costs compared to plastering a falling wall - this is an important advantage.

To start work, the necessary material is calculated:

• the guide profile is purchased in double the size of the perimeter;
• rack profile - the quantity is equal to the ratio of the perimeter of the room to the width of the drywall (standard 1 m 20 cm), multiplied by two, plus 4 corner;
• anchor wedges or dowel-nails - divide the perimeter by 50 cm and multiply by 2;
• self-tapping screws for metal - the number of rack-mount profiles is multiplied by 4;
• GCR - divide the perimeter by 1 m 20 cm;
• self-tapping screws on the GKL - divide the perimeter of one sheet by 60 cm and multiply by the total number of sheets;
• sickle - the number of rack profiles is multiplied by their height;
• deep penetration primer - 150 ml per 1 sq. m.;
• putty for joints - depending on the manufacturer, the consumption is different;
• putty on GKL.

Frame alignment allows you to create the perfect geometry of the room, it is suitable for any type of finish.

With the help of a laser level, the frame of the structure is marked, the guide profiles are fastened with anchors or dowels along the lined marks on the ceiling and floor.

Rack profiles are cut at the ends, petals are created through which self-tapping screws are screwed. They are inserted into the guides and fastened at a distance of 60 cm from each other.

Sheets of drywall are screwed to the finished frame, in steps of 0.6 m, the caps of the self-tapping screws are sunk.

The seams are rubbed with a special putty, it is more elastic. In order to avoid the appearance of cracks, a sickle is embedded in the putty.

Putty is used to finish the surface leveling: a mixture is prepared, which is smeared over the entire surface. In order to save time on processing and on the cost of the finishing layer, GKL should be chosen with beveled edges, then the difference in height will be insignificant. You can cut the edges yourself.

In addition to drywall, other materials can be used for frame leveling: fiberboard, chipboard, pvc panels, plywood, lining and a more modern OSB board.

Advice! The choice of alignment method depends on personal preferences and financial capabilities. Therefore, before starting repairs, it is worthwhile to paint all possible types of finishes, their cost, and then make a decision.

Wet leveling

Leveling the walls with a mixture is a more time-consuming and dirty process. But it allows you to save space, and in some cases finances - with minor deviations, the consumption of the mixture will be less. The method of alignment depends on the requirements for the final result.

There are two ways to do work: by beacons and by rule. Perfect alignment of wall corners is impossible without beacons and corner elements. Such a laborious process is relevant for the bathroom, for the kitchen. Here the geometry of the room is very important, when installing furniture of the correct form, minor errors become noticeable. Leveling tips from the pros:

In practice, two methods are often combined: walls with windows and doors are aligned with beacons, and other walls are aligned according to the rule. Also, careful alignment with beacons requires rooms with external corners.

The choice of mixture for leveling the walls depends on the finish coating. It can be wallpaper, paint, decorative plaster.

Alignment of walls for wallpaper depends on their type:

• under a light thin coating you need a light base without the slightest error;
• glass and vinyl wallpapers of a dense texture can hide minor flaws in the base;
• liquid wallpaper, depending on the grain size, requires a perfectly flat plane or allows small flaws.

Aligning walls for painting always requires a perfectly flat surface. It involves several stages of puttying and the use of a quality mixture. The choice of polymer putty allows you to prepare the surface for painting in one stage of puttying without sanding and re-puttying.

Decorative coarse-grained plaster does not require wall puttying, plastering is enough for an even base, smoothness does not matter.

Important! Regardless of the number of layers and top coat, each stage ends with a primer. It is necessary for better adhesion of layers and material savings.

Difficult cases in alignment

How to level the walls in a wooden house? For this case, it is acceptable to use both methods of work, but the wireframe version is preferable. The technology of work is the same as described above.

An important point is the height of the sheathing material in a house that has not settled, it should be 5-10 cm less than the walls. Leveling with a mixture is a more laborious process: it requires careful treatment of the walls with an adhesive composition, attaching shingles or mesh to hold the plaster. The preliminary lining for plastering looks like this.

Even in modern new buildings, you can meet clay walls. This material is characterized by low cost, good hygroscopicity - ideal for use in residential areas. How can you level rare clay walls?

In fact, nothing complicated: leveling occurs by plastering and puttying with lighter or balanced mixtures. Gypsum or clay mixtures are suitable for this.

Aligning the outer corner of the wall with your own hands becomes much easier if you use a special perforated corner. It can be narrower and wider, depending on the need. The corner creates perfectly smooth sides, remains in the plaster. For puttying, it is convenient to use a special angular spatula, which will require a minimum of skills and effort.

Aligning the corners in a room of irregular geometric shape with your own hands is a very time-consuming process. Using drywall will steal more space than plastering, but will go faster. In any case, the corner elements are installed perpendicular to each other. Then, on the same line with them, beacons are attached to the alabaster along the wall. The laser level simplifies the process of aligning beacons and corner elements. The most crucial moment has been completed, it remains only to fill the space between the beacons with plaster.

Material selection

For high-quality finishing, its speed, convenience of work, material and tools are important. They are not worth saving.

Mixtures for leveling walls are available in different grain sizes and whiteness. The more expensive the mixture, the less trouble it will have. Ready-made compositions of plasters and fillers are especially convenient, which are ready for application without dilution with water. Such mixtures are distinguished by a long preservation of properties even when open, which is very important for beginners - after all, conventional solutions dry quickly and are inconvenient to apply. Ready formulations are sold in buckets, after use, leftovers can be stored in a bucket until the expiration date.

White putty saves painting costs, it is necessary for light wallpaper. Therefore, when choosing, it is worth clarifying the color of the mixture, if it is necessary to align the walls in the apartment under the wallpaper.

High-quality drywall does not crumble, does not have chips - its processing will be much faster. The presence of factory chamfers (image above) on the sheet saves the overall consumption of the finishing mixture and finishing time. The same applies to profiles - rigid profiles create a strong frame and are not subject to deformation during installation.

Advice! When choosing cheap material, you should not count on a quick repair, such savings will require more patience and skill in work.

It's nice to improve your home with your own hands, but the wrong approach can spoil the mood. Before starting repairs, you need to soberly assess your strengths, study the necessary information. You can always entrust the work to professionals.

The durability and appearance of the finishing of the walls largely depend on the quality and correctness of the preliminary leveling of the base. Therefore, it is very important to learn how to level the wall with your own hands in order to obtain a perfectly flat surface. Before proceeding with the decoration of the walls with tiles, wallpaper, paint and other materials, it is necessary to eliminate irregularities and any kind of surface defects. Even the slightest flaws will eventually lead to a noticeable deterioration in the appearance of the finish, and you will have to redo the repair.

Ways to level walls

The curvature of the walls can be leveled in two main ways, namely:

• wet, involving the use of various kinds of mixtures;
• dry, carried out by arranging plasterboard structures.

Both methods have many advantages and some disadvantages.

It is usually used to eliminate minor differences (up to 30-50 mm) in walls of a small area. If desired, of course, with the help of a plaster mixture, more significant defects in huge rooms can be eliminated, but this will lead to irrational financial and labor costs.

Building mixtures do not reduce free space, and this is their main advantage. However, wet leveling is inevitably accompanied by the formation of dust and dirt.

Drywall allows you to eliminate large drops and uneven surfaces.

The main advantage of drywall constructions is that there is no need to pre-level the base before installing the frame and the sheathing sheets directly. It is only important that there are no crumbling areas of finish.

In addition, the cells of the supporting structure can be filled with noise and heat insulation. If necessary, various kinds of communications are easily hidden in the plasterboard structure.

At the same time, the installation of the frame and sheets leads to some reduction in the usable space of the room.

On sale are simple and moisture-resistant modifications of drywall. Material with moisture-resistant properties is usually green, while simple drywall is gray.

Preparing walls for leveling

Before proceeding with the alignment of the walls, the surface must be properly prepared. In particular, the preparation of the base before plastering is important. In the case of arranging a drywall structure, preliminary preparation in most situations can be waived.

Preparation is reduced to the elimination of existing finishes and old plaster. Next, the surface is primed. Brushes and rollers can be used to apply the primer coat, but the best result is achieved when using a sprayer. Thanks to the primer, the quality of adhesion of the plaster to the surface of the base will be improved.

The primer dries in about 12 hours. After this time, you can start applying the plaster composition.

Leveling walls with plaster

Work begins with the installation of special beacon lines. They will allow you to apply the highest quality.

First step

Fix the beacons on different sides of the wall being processed. Check the verticality of the installation of the profiles with a plumb line.

Second step

Prepare about 10 liters of cement mortar (you simply won’t have time to use a larger amount until the mixture becomes unusable). Instead of cement plaster, other existing mixtures can be used.

Third step

Apply in large strokes to the surface between the beacon profiles.

Fourth step

Carefully align the applied mixture along the beacon profiles. For alignment, use a rule or a simple, even rail of a suitable length.

Add the mixture and spread it over the surface until the base is level with the beacons.

Carefully trim the corners with a spatula.

If you decide to use a factory dry mix, prepare and apply it according to the manufacturer's instructions. When choosing such a mixture, be sure to pay attention to the type of "binding" component.

So, gypsum-based mixtures are intended for use in living rooms, because. gypsum does not violate the normal microclimate in the room. Cement plasters are better suited for bathrooms, kitchens and other rooms with a high level of humidity.

Leveling the base with drywall

If the dimensions of the base irregularities exceed 50 mm, it would be more rational to use the method of leveling the walls, which involves the arrangement of a plasterboard structure.

Any special - the main thing is that there are no crumbling fragments on the walls. Clean up such areas if found.

The frame for fastening the sheets is assembled from a galvanized profile specially designed for this. Several types of profiles are used.

The main UD profile is attached to the ceiling, floor and adjacent walls. Jumper functions are performed by the CD-profile.

First step. Attach the vertical profile to the previously listed surfaces. Use dowels to fix. As a result, you should get a reliable support frame.

The first profile must be installed directly next to the side wall. Fasten the following profiles in 60 cm increments. The second end profile must also be fixed close to the wall, even if the distance between it and the nearest profile is less than 60 cm.

The standard width of the sheathing sheet is 120 cm. With the mentioned profile spacing, the plasterboard panel will be fixed at the edges and in the center. In this case, measure the distance from the center of the profiles.

Second step. Proceed with the installation of jumpers from the CD-rails. Sheathing sheets will be attached to these profiles.

Fasten the profiles with their edges to the surface of the base, turning them with a wide edge into the room.

Use self-tapping screws to connect profiles.

To strengthen the structure, special suspensions must be included in its composition. Stiffening ribs are located in the center of the suspensions, the ends of the products are perforated.

The suspension must be bent in the form of the letter U and attached to the wall under each vertical profile. Place the fastener in the center of the suspension. Attach the "ears" of the hangers to the profiles.

Control the evenness of the installation of profiles.

Proceed with the installation of sheathing sheets. Use self-tapping screws for fastening. At this stage, you will need an electric screwdriver - with its help, the work will go easier and faster.

Embed the heads of the self-tapping screws into the material. Place self-tapping screws in increments of 100-150 mm. Fastening is carried out in the center of the sheet and along its perimeter. Typically, center lines are present on the face of drywall sheets to facilitate fixing.

If the length of the sheet is not enough to cover the entire height of the surface, add in the missing places. The sheet cutting technology is as follows: you cut the top paper layer, carefully break the sheet in the required place and cut the second paper layer.

Attach additional pieces to the jumpers from the CD-profile, fixed between the vertical posts.

After sheathing the entire frame, you just have to putty the joints of the sheets, treat the surface with a primer and finish with the selected material.

• the presence of rounded edges;
• reinforcement of the material with fiberglass;
• easy to process.

Smooth walls are the key to perfect repairs and often the most expensive of all procedures. To reduce the price of work, many people ask themselves the question: how to level the walls with their own hands.

The first thing to do is to understand why you need perfectly smooth walls. The alignment of the walls in the apartment is usually due to pasting wallpaper and the correct geometric shape when arranging furniture.

Walls don't need to be aligned if you're using live wallpapers. They smooth out small irregularities and for them it is not fundamentally a perfectly smooth surface (for example, bamboo wallpaper).

The process itself is presented on the Internet by many videos and photos of wall alignment. Also, before starting work, I would like to advise you to seek help from people who already have experience working with plaster and subsequently read the instructions on the packages with mixtures more carefully.

Types of alignment

If the alignment of the walls cannot be avoided, then this process can be done in several ways. Plasterboard leveling is the least time consuming. To do this, you just need to attach sheets of drywall to the wall, armed with a level.

The list of plaster for interior work is large. It comes with various impurities. If you bought an apartment with already aligned walls, then most likely they were leveled with ordinary sand concrete, but the evenness of such walls must be rechecked.

If you have small differences in the level of the walls, then you can also do this work with sandstone. However, it should be borne in mind that the degree of its drying is longer and therefore the work may be delayed.

How to level the walls with plaster, before this question, you need to be puzzled by others, which plaster to choose. Based on experience, it is better to choose gypsum.

Plaster

If you have chosen leveling with plaster, then in addition you will have to purchase beacons (this is if you have the rest of the materials and tools).

Alignment of the walls along the lighthouses is their correct installation. First, we set up beacons throughout the room. Along the height of the wall, every 30-40 centimeters, we install a dowel with a self-tapping screw into the surface. Usually such “columns” are made at a distance of 80-90 cm from each other throughout the room.

The main thing is that they are all the same. Applying equal to the heads of self-tapping screws, we set the level over the entire height. We do this procedure with the whole room.

We knead a small amount of plaster and fix the beacons on these planes. At the junction with self-tapping screws, we strengthen with plaster. After the procedure is completed, we wait a while and let the plaster dry.

We prepare a mixture of plaster based on the information written on the bag. We throw the finished mixture between two beacons starting from the bottom. Then we take the rule, set it between two beacons and begin to lift the mixture from the bottom up with wiggles. We make such movements until the mass is leveled.

Remove the rest of the mixture from the rule with a spatula and throw it on a non-plastered area. At this rate, we finish all the walls. The walls should be even and smooth. Depending on the type of plaster, the walls turn white, due to the presence of gypsum in the mixture.

putty

After the plaster has dried, we can begin to putty the walls. Putty is needed to remove small porous holes and bring the state of perfect smoothness.

After puttying, we can begin to remove the beacons. In order to remove them, you need to pry from the bottom with a screwdriver and pull them out along the entire height. Do not be alarmed, we close up the resulting gap with plaster and the rule.

It is possible to level the walls simply with putty, but this case helps when the wall distortions are not so great. Permissible deviation is not more than 5 mm.

Drywall

Alignment of walls with drywall is of two types. One has already been described above, but I want to dwell on the other in a little more detail. If you have very strong differences in the walls, then it is cost-effective to level them with drywall.

To do this, a frame is made along all the walls. A guide profile is attached to the level of the floor and ceiling. On them, every 60 cm, a vertical profile is installed. And drywall sheets are attached to this entire installation.

The joints must be glued with a special mesh and all irregularities and holes from self-tapping screws should be covered with putty.

If you want to make the walls some kind of figured, then only drywall will help, because under other conditions, the consumption of materials will be gigantic and cost a pretty penny.

Smooth walls in our life are not a tribute to fashion, but a vital necessity. Improperly aligned walls can make life in your home miserable. The most harmless is constantly peeling wallpaper, but the worst thing is various fungi and bacteria.

Before leveling, determine if it will be easier for you to knock down some sections of the walls to reduce material consumption.

In Soviet times, the walls were lined with plywood sheets, but it has poor moisture resistance. Also, the joints of the sides of plywood sheets had to either be decorated or left as is.

As a result, for better work, it is better to sand what has been done in order to remove microcracks invisible to the eye.

Wall alignment photo

Walls are the first thing that catches your eye in an apartment. Their uneven surface can greatly spoil the impression of the home, even if it is incredibly pompously decorated. In simple interiors, wall defects are especially noticeable. The only way out in this case is to level the surface. Of course, you can use the services of a wizard, but try to do it yourself. I am sure that with our recommendations you will certainly succeed.

Preparing for alignment

Before leveling the walls, you need to perform a number of operations. First you need to set the frame of irregularities. To measure horizontally, you can use a cord that is pulled tight along the wall. It is even easier if you have a building level at least 1.5 m long. A plumb line is used to calculate vertical irregularities. Differences of no more than 3-5 cm are leveled with the help of special building mixtures. In this way, more curved walls can be leveled, but it will take a lot of time and money.

This is the so-called wet method of leveling load-bearing structures. In the dry method, the walls are sheathed. It is used if the walls are too curved. The latter method is more time consuming, but allows you to achieve perfect surface smoothness. In both cases, the key to success is strict adherence to the sequence of actions.

The plaster must be carried out quickly, because the solution for it dries quickly

Regardless of the method chosen, it is necessary to responsibly approach the alignment of corners. curvature imperceptible at first glance may appear when installing curbs or.

Plaster or drywall: all the pros and cons

Both types of wall alignment have both positive and negative qualities. This requires pre-cleaning of the surface. Elements of old plaster can affect the quality of installation of the material using a special adhesive.

Behind the installation, you can easily hide noise and heat insulating materials, hide communications and wiring. The problem is that drywall reduces the size of the room somewhat and can withstand less stress than walls covered with mortar. Pay attention to the color of drywall sheets. Moisture-resistant material is painted in green, and normal - in gray. In bathrooms, kitchens and other rooms with high humidity, it is better to use GKLV sheets.

If you prefer building mixtures, the room will retain its original dimensions. However, even here there are buts. The surface will be monolithic, without gaps between the wall and the layer. On curved walls, a large layer of the mixture is obtained, up to 5-10 cm) and a lot of material is required. As a result, this method is rarely used. To carry out such repairs, you will need to remove all furniture, and after completion of work, carry out a thorough cleaning of the room.

Wall plastering

Before starting work, you must completely turn off the electricity in the apartment. After the surface is thoroughly cleaned of old wallpaper, plaster or paint. Then treat the surface with a primer. In this case, the building mixture will be better fixed. The primer increases moisture resistance and prevents delamination of materials. For cement mixtures, a solution of cement, water and sand is used. To make the wall as smooth as possible, it is necessary to fix beacons on it. To do this, profiles are installed on the sides of the wall. The verticality of the beacons is checked by a plumb line.

Dilute about 10 liters of cement mixture and apply it to the wall with a construction spatula in large strokes. Then align the solution along the beacon lines from the bottom up. To do this, use a level or a wooden board. The solution must be added until the surface of the wall is aligned with the beacon lines. When using a spatula, it must be tilted 45 degrees. In this case, the surface will be perfectly flat. Do not forget about the corners, be especially careful in finishing them.

When working with dry mortar, pay attention to both the thickness of the applied layer and the type of bonding material. Gypsum-based compositions are usually used for finishing living rooms. This material well supports a microclimate of rooms. Cement mortars are mainly used in high humidity environments (bathrooms and kitchens).

How to level walls with drywall

The second and most popular way to level walls is to use drywall sheets. It is usually used if the size of the irregularities on the wall is more than 5 cm. The plasterboard wall must be protected from moisture, freezing and condensation. For reliable fastening of drywall sheets to the adhesive, it is recommended to clean the wall from the remnants of the old mortar. Then the surface is primed.

If the surface of the wall is loose or porous, it is better to use a deep penetration primer. It is applied with a sprayer or paint brush. On concrete and other low-porous surfaces, a special primer is applied with the mark “concrete active”. Before you install drywall sheets, do not forget to wire. Boxes for sockets must protrude at least 20 mm above the wall surface.

After the plaster is completed, the beacons are removed, and the strips after them are rubbed with plaster

Glue plasterboard sheets directly on the wall or install on metal frames. Corner irregularities are eliminated using special metal profiles. To install this type of construction, it is necessary to use self-tapping screws, dowels and a screwdriver. Places for metal structures are marked with a pencil.

conclusions

Self-alignment of the walls requires a careful approach and the choice of the appropriate method of work. The main thing is not to despair and to approach the matter with responsibility.
