How to plaster a doorway. How to plaster slopes: all the nuances and subtleties of the matter. Key data and benefits

Plaster door slopes is a finishing operation that helps make surfaces more visually pleasing. At first glance, it may seem difficult to implement. But in fact, plastering door slopes is quite simple and will not cause serious problems even for beginners.

As a rule, when changing and installing door frames during the work process, many layers of plaster are removed from the walls, and sometimes entire pieces of material are separated. Even with extremely careful performance of all actions, cracks and chips may remain in the gaps. Therefore, plastering is necessary not only to improve the aesthetic appeal of slopes, but also for practical purposes. It will create a layer impenetrable to external influences, which will provide the room with heat and sound insulation when the doors are closed.

Before plastering the door slopes, you should carefully prepare for the work. First of all, you need to decide on the choice of materials. Finishing can be done with mixtures for external or interior work, frost-resistant and moisture-resistant compositions are available for sale, the choice of which must be based on the characteristics of the room being repaired.

Stock up necessary materials in advance. When everything is purchased and collected in one room, you can begin to prepare the solution. The classic plaster composition is mixed from 1 part cement and 3 parts sand. When working with plaster mixtures, follow the manufacturer's instructions. All the tools that will be needed for the job are also prepared in advance.

For high-quality execution plastering you may need:

• drill with attachment;
• polyurethane foam;
• liquid Nails;
• plaster mesh;
• perforated corners;
• masking tape;
• level and rules;
• spatula of the required width;
• primer brush;
• emery.

Plastering the doorway and slopes is considered in the classic way to complete the finishing of these elements. This is how you can make slopes different sizes, any width and shape. This method is especially valuable when working with arched openings– for them, another finishing method is not possible. The solution fills the cracks well, which allows you to create a solid structure and additionally provide insulation of the opening. Plaster surfaces They are quite environmentally friendly, they will not be difficult to update or restore if necessary.

How is the plastering process carried out?

Before plastering the doorway, the wall should be leveled. The mixture for finishing is selected depending on exactly how the door is located. Plastering door slopes can be internal or external.

The work is carried out as follows:

1. When installing doors side elements the boxes are placed at the same distance from the right and left walls.
2. The cracks are caulked with insulating material, which should be compacted more tightly to fill the free space as much as possible.
3. Before plastering the slopes, their surface should be cleaned and beacons installed to help level the surface.
4. The surface is finished using cement mortar or plaster mixture for facade work.
5. To process doorways, the choice of plaster mixture is made taking into account whether the premises are residential or non-residential.

If it is necessary to plaster an arched opening or one in which doors have not yet been installed, this work is performed using guide profiles installed on both sides.

For slopes plastering and finishing can be made using cement-sand mortar. To begin with, the surface should be carefully prepared. Carefully remove the remaining paint and putty, old layers of plaster. Sometimes it is necessary to make small notches on the layer of plaster that is being prepared for coating with the next portion of the mortar. This operation allows you to improve the level of quality of adhesion of the layers. Before applying cement mortar, the base should be moistened. Guide rails are installed along the edges of the door.

To completely eliminate the defects resulting from the hardening of the layer, use a grater or fine-grained sandpaper. Before applying the plaster, the surface is treated with a primer. Create a draft barrier before plastering to improve adhesion of materials and keep the mixture in working condition for the time it takes to apply it. After covering the surface with the final layer of plaster, you can wait until it dries and paint it.

When installing doors, you need to make sure that both parts door frame were at the same distance from opposite walls. After installing the door, check the reliability of its fastening.

A doorway plastered in this way receives additional noise and heat insulation.

This type of work such as plastering slopes is one of important stages doorway finishing. Not only does the quality of work depend on appearance doors, but also its important ones performance characteristics. Let's take a closer look at the technology and features of doorway putty.

Plaster - great option slope finishing

Why plaster slopes

Plastering the slopes of a door or window opening is of great importance, so a lot depends on the quality of the work. We can identify the main reasons why such surface treatment is performed:

• Crevices. Using putty you can eliminate all cracks, gaps and cracks around the perimeter of the opening. This will have a positive effect on sound insulation and heat retention.
• Finished look. The slopes take on a neater appearance, the door is ready for use, and dirt and construction dust are eliminated.
• Decor. Plaster gives the opening an aesthetic appearance and can act as the main design.
• Base for a different decor. In addition to plaster, you can use paint, wallpaper, tiles, MDF panels and other similar materials. However, in any case, you need to first level the slopes and create a suitable surface for finishing.
• Protection. Thanks to putty, it is possible to hide the mounting foam from ultraviolet radiation, which is a prerequisite for preventing its destruction.

Plastering of door slopes is carried out to protect and decorate the opening

Plastering slopes with your own hands is a very real task. To make the process easier, you need to prepare everything necessary tools and select suitable materials.

Selection of putty

Which putty to choose for finishing slopes with your own hands? Modern construction market famous huge assortment, therefore, depending on the specific conditions, you can choose exactly the mixture that suits you best. The entire range can be divided into the following categories:

• Cement. Durable and quite moisture resistant, but after drying they shrink.
• Plaster. Homogeneous, easy to apply, provide smooth surface, but do not like a humid environment.
• Polymer. Waterproof, easy to use, durable, but expensive.

In addition, plastering slopes with your own hands is often done in several stages. For the base coat you will need a starting, stronger but coarser mixture. It must be leveled with a plastic and uniform finishing putty. Some manufacturers offer universal formulations, but their cost is much higher.

Types of putty used for finishing door slopes

If you are planning further surface finishing of the opening after plastering the slopes, you can use the standard cement-sand mortar for basic filling of cracks and smoothing out uneven surfaces.

Required Tools

Do-it-yourself plastering of door slopes is impossible without certain tools. First of all you will need:

• rule;
• set of spatulas;
• container for diluting the mixture;
• construction mixer;
• construction float;
• level;
• corners;
• serpyanka;
• primer;
• stationery knife;
• brush.

List of tools required for plastering door slopes

How can you plaster slopes? different methods, additionally you may need metal grid, as well as drywall and a profile for its fastening. Be sure to stock up on a set of screws for different surfaces. To fix them you will need a drill and a screwdriver.

In order not to smear the box and adjacent surfaces with plaster, cover them with masking tape before starting rough work. It is recommended to lay a film on the floor. If possible, remove the fabric from its hinges for a while. Concerning new door– it is recommended not to remove it protective film until the repair is completed.

Preparing the opening

In order to facilitate plastering of door slopes, work area need to be prepared in advance. This includes a whole list of works. Since such design of slopes is almost always associated with updating the door itself, you first need to eliminate all the defects and irregularities that remain after replacing the frame.

First of all, cut off the excess polyurethane foam with a sharp utility knife. If the unevenness is too significant, it is best to use it as a base for plaster. plasterboard sheet. Choose moisture-resistant samples to extend their service life. There are two ways to attach this material to the opening:

• On glue. This simplest option, allowing you to save space. To begin with, a layer of plaster is applied to the slopes. You can use leftover tile adhesive or regular tile adhesive. homemade solution. Then drywall is applied to the wet viscous mass and pressed. Thus, you need to drive an even level around the entire perimeter of the opening.
• On the frame. If the distortions are too significant or you simply don’t want to waste putty once again, then use the traditional approach and screw the sheets the desired shape and size k aluminum frame. These elements are screwed to the slopes using self-tapping screws and dowels. Using this method, you can create an unusual shape for the opening, for example, create a rounding at the corners, like an arched vault.

Drywall is often used to level door slopes.

If there are gaps and cracks in the opening, they need to be closed using insulation. Typically used for this mineral wool. In order for the plaster on doorways to set better, it is recommended to cover the slopes with a special mesh. Serpyanka is glued to the deepening places of the self-tapping screws on the plasterboard and in the corners. A larger metal mesh can be nailed directly to the wall.

Finally, you need to treat the surfaces with an antiseptic and carefully prime them to improve adhesion. The next stage is directly plastering the slopes with your own hands.

Plaster application technology

Let's look at how to plaster the slopes of a doorway. The whole process can be divided into several stages:

1. First you need to repair the largest irregularities. If you are laying the mass directly on concrete with a mesh, you must use a starting putty. First, a small amount of the mixture is thrown onto the slopes in the direction from bottom to top, and then leveled with a large spatula. Excess is transferred to the upper level. For drywall everything is simpler: you need to seal it finishing mixture places for deepening screws.
2. It is important to get straight corners. To do this, secure around the perimeter aluminum profile and mesh. Apply the mixture on top of them with a small spatula and check the thickness of the layer with a large tool.
3. After initial plastering of the slopes, wait completely dry surfaces. If there are significant irregularities, it is recommended to remove them using a construction trowel.
4. Since you need to plaster the slopes to perfection flat surface, you need to apply the finishing composition on top. With its help, all irregularities are eliminated.
5. After drying, float the surface and remove dust before further finishing.

An important step in applying plaster is creating even corners

Since it is not easy to putty slopes in several layers, you can improve the adhesion of the mixtures by applying shallow notches to the starting layer before it dries.

If you are planning to paint or wallpaper, you need to try to create the perfect smooth slopes. For textured plaster, tiling and panels, initial treatment will be sufficient. However, if you plan to replace the coating in the future, it is better to initially bring the surface to perfection.

When renovating an apartment, you often have to tint the windows, and sometimes putty and plaster them so that they have the proper appearance. This work does not take much time and effort and does not require special skills. In the process of replacing windows, especially with metal-plastic ones, the work becomes much more, because you need to eliminate the empty space from the second frame, level the slope and cover it with plaster as evenly as possible, which requires knowledge, and most importantly, skills.

Peculiarities

Repair and replacement of windows are accompanied by distortion of the opening and the need to work on it. You can call specialists and they will do everything necessary, but this will require significant financial costs, while the process of plastering slopes can be done with your own hands. The main thing is to find out how to do it correctly. Slopes on windows do not play a global role in the interior, but when installing a new window, it is much nicer to frame it with fresh elements, rather than leaving it surrounded by uneven homemade parts of the wall.

Plastering window slopes is not a very labor-intensive process, but it requires knowledge of certain things:

1. It is important to consider the room temperature when planning your work process. After all, if it is below five degrees Celsius, then cement and any other mortar will have the wrong consistency and will turn into stone much faster.
2. When purchasing any dry mixtures, you must dilute them only according to the instructions indicated on the package.
3. The scope of plastering work can be different, according to which it is necessary to correctly mix the solution in quantity. Within half an hour it will begin to dry out and it will no longer be possible to use it.

If the unevenness on the side of the window opening is too large, then you need to apply a rough layer of putty. This way you can level the surface as much as possible, and after it dries, use finishing putty Corrective actions will be taken.

The result will be a smooth and neat slope in the room where the window replacement work was carried out.

When should it be done?

Good repair involves replacing the entire contents of the room, including windows and doors. Modern double-glazed windows are very easy to install and serve well. However, there is new problem, associated with destruction from the dismantling of old windows and doors. To hide holes and irregularities, you need to plaster them yourself or hire a team of specialists. If repairs need to be carried out in as soon as possible and quality, then the help will not be superfluous. If it’s just one window or door, you can completely handle it yourself.

After installation plastic windows or front door internal walls experience varying degrees of destruction. They must be removed immediately. For external window walls, most often there is no need to change anything, although if desired, they can be leveled and plastered for painting. Inside the room it is very noticeable when old slopes remain on a new window, made without taking into account the technologies and rules for working with them.

It is believed that window space has a small role in the interior. Even if it does not decorate the room to a significant extent, poor work will immediately catch the eye and spoil the impression not only of the renovation itself, but also of the owners of the room.

To achieve the perfect result and make the room completely harmonious, you need to work on the slopes of windows and doorways if they have been replaced.

Despite its insignificant significance, the window slope still performs a number of important functions, these are:

• ability to hide mounting elements;
• additional thermal insulation;
• protection from moisture;
• soundproofing.

As soon as you plan to replace windows or doors in a room, it is important to consider working on slopes and openings. This is important, because this way the process will be completed faster, and the room will get a complete look without losing its functionality.

Tools and materials

For efficient work for plastering slopes, it is necessary to prepare tools, without which it will be difficult to achieve good result. Regardless of whether the work will be done on a window or a door, the same tools are needed, namely:

• Level with a minimum length of 1 meter.
• The rule is that there will be no damage or distortion on the ribs. This is the main tool for leveling the solution on the surface, so it must be perfectly level.
• Roulette.

• Container for mixing the solution. Its dimensions should be as convenient as possible for connecting the necessary components.
• Spatulas of different sizes. In the work you will need both narrow, medium, and wide. They apply the mixture and level it in small areas.
• A trowel, with which you can properly distribute the composition and make the surface smooth.

• A grater, which is selected based on the plaster used.
• A construction knife so that you can conveniently remove residues from polyurethane foam.
• Caulk gun.

• Several pencils for marking. Using a marker or felt-tip pen may cause stains to appear on the finished surface.
• Brushes and a roller to prime the surface.

Since the main work will be carried out using plaster, this material must be selected with the utmost seriousness.

For rooms with high humidity or outdoor work you need to use mixtures with cement. For indoor work with slopes, the best plaster composition will be gypsum.

In addition to the basic tools and materials, it is important to have additional ones at the ready:

• polyurethane foam in case too much large holes from an old frame;
• a tube of sealant to seal the seams at the foam cut and cracks on the slopes;
• primer composition;
• corners or strips that act as beacons.

The use of dry mixtures is justified because you can make the batch yourself required quantity and density. For use gypsum putty it is important to install a profile, which can be either metal or plastic, but it is better to choose the first option.

If you have no experience plastering works, then it is better to use a mesh, which will speed up the application of the mixture and help level it better.

The window block can be designed in different ways:

• smooth slopes that form square windows;
• corner structures that help, if necessary, visually expand the space.

If work is carried out on a doorway, then you can not only level the surface of the wall, but also prepare it for future decoration. Depending on the style of the room, you can install pillars at the doors that will look like antique columns. This is typical for classic style. You can find an original frame and trim that will highlight the interior of the room.

When starting to repair slopes and openings, it is important to prepare the room itself. Everything around should be covered with something or protected from dust and dirt, which will certainly arise during work.

Before starting any repair actions, it is important to study all the characteristics of the materials that will be used in the work. This step will help prevent serious mistakes and speed up the pace of work.

Application process

Before starting work, you need to prepare the window itself for repair. The window sill must be covered, and the window must be covered with film and covered with masking tape. Finishing a slope with your own hands will not be so difficult if you adhere to all the rules and regulations in this type of work.

• The first thing to do is remove the remaining foam, after which you can attach the slats. Any plank will do, but it is important that it has the right length, is not too wide, and is durable.
• The slats are attached to the window opening using a mortar of gypsum and plaster. From the outside, they are treated with a primer and left to dry completely. After this, the plastering process begins.
• The surface on which the material will be applied must also be primed. This will provide better grip with the new material.

• If the window opening is made not of brick, but, for example, of cement, then it is necessary to install a special mesh or prime the surface.
• The next step will be to check the evenness of the slopes and identify the most uneven places in order to fill them with the solution first. Application can be done using two technologies: spreading the mixture or throwing it on. The second layer is applied using a grater rather than a spatula.
• It is very important to properly level the surface, because the final result will depend on this. Additional measure there may be plastering of the corner connecting the slope and the wall.
• The treated surfaces are rubbed and finally leveled until the result is perfect. If you have no experience in such matters, then you can ask your friends or hired craftsmen to show them a master class on exactly how to make slopes and doorways after dismantling old structures.

• The window surface to be plastered must be completely ready for work; care must be taken to clean the top layer of dust and dirt that remains from dismantling works. When preparing the mixture, it is important not to make too much of it, because the plaster dries quickly, after which it can no longer be used. To decide on optimal quantity solution, the deepest part of the slope is measured, from which the initial calculation is made.
• It is most convenient to apply the mixture to the wall using a medium-sized spatula, and as a rule it is very convenient to do flat angle. To level the surface, it is convenient to take a large spatula, which will be slightly larger than the width of the slope.
• To extract an unnecessary amount of solution, the spatula is set at a right angle and carried out from bottom to top, like any other movements on window opening. All excess that has formed on a large spatula can be conveniently removed with a medium one.

• There is no need to level the resulting slopes to perfection, because the next stage of work will be the use of a grater. She will level everything to the required state.
• When applying layer after layer of plaster, it is important to wait time for drying. If there are only two of them, then half an hour will be enough. If there are more layers, for example four, then they can dry up to a day. It is thanks to the application of each new layer of plaster that it is possible to level the surface of the slope, which is checked each time with a level.
• At the end of all this work, the plastered slopes can simply be left with putty applied to them.

If subsequent painting is planned, then they should be additionally primed. This option is more reliable and will make painting easier, as it will improve the adhesion of the color to the surface of the slopes.

Plastering door slopes is quite important. After all, this is not a simple flat plane; there is also an angle, and it can be different.

Today we will look at how to plaster door slopes and, accordingly, adjacent corners. You can watch some moments of the work in the video in this article and photos. After this, you can do everything yourself.

Pros and cons of plastering slopes

For finishing slopes there is big choice materials. This includes drywall, wood and plastic panels. However, simple plastering is still in demand.

Choosing the right tool is important

First of all, it is decided how to plaster the slopes of the front door. After all, when starting any business, you must first of all take care of the tool (see Tools for plastering walls: what you will need for the job). Its choice always depends on the materials used.

When plastering slopes we need:

• Level preferably with two ampoules
• Aluminum rule
• Goniometer
• Yardstick
• Marking pencil
• 5 cm spatula
• Mason's trowel
• Hammer-pick
• Vessel for preparing working solution
• Container for water

When choosing a tool you will need to consider the following:

• It is difficult to work with a short level, and a long level simply will not fit between the cornice and the lintel. The most the best option there will be a meter level. For minor work you will also need a special gun for sealant and construction knife. And for sealing joints and cracks - a cylinder with polyurethane foam.
• When using cement mortar, additionally prepare a trowel and float. And to work with plaster - a grater with a sponge base, a spatula 45 cm wide and a polishing iron of large and small sizes.

Select the right size for work shoes and clothing; they should be comfortable and not restrict movement. Medical gloves can be used to protect your hands.

The surface can be plastered

To make a door with your own hands, or order it from a workshop, it is very important to “take measurements” correctly. An inaccurate measurement of the front door opening, at best, will lead to the formation of large gaps that will have to be sealed and insulated. In the worst case, you will have to think about how to increase doorway, which will cause even more trouble.

Sometimes it is necessary to build a partition or pier into which a door of a given size will be inserted. But sometimes you have to solve more serious problems - for example, building an opening where there has never been one.

By request: “Preparation doorways video”, you can always find a suitable video where masters share their experience. For our part, we will try to give you theoretical knowledge, based on building regulations and technology - after all, the opening must not only be correctly calculated, but also properly leveled.

So:

• The easiest way, of course, is when the construction of a house is carried out, as it should be, according to the project. The documentation contains a diagram for filling doorways, approximate version which you see below. It indicates the sizes and types of doors, as well as gaps in the walls where they will be inserted.

• As a matter of fact, when building walls, masons immediately make the openings that are needed - the main thing is that they have accurate information on the markings of doors that will be installed in load-bearing and self-supporting structures. But as for partitions, then for internal layout Most often today they invite not masons, but drywall specialists.

Design device in GVL partition(see) - the procedure is not so complicated and can be done independently. But, of course, you need to approach the work with understanding, and try not to confuse anything regarding the size of the opening.

After watching the video in this article, you will be able to cope with the task. We offer you further small instructions about this theme.

Opening in a frame partition

The thickness of a wooden door frame is on average 5 cm - it is this distance, coupled with the size of the door leaf, that is the full dimensions. All instructions for measuring the opening for installing a door boil down to adding a value around its perimeter installation gap, which should be within 3-6 cm.

It is then sealed with polyurethane foam. Deviations of a couple of millimeters are not critical, but it is better if they are larger.

Note! Maybe not everyone knows that the door markings, in decimeters, encode the size of the door leaf, taking into account the thickness of the frame. If, for example, it is necessary to install a door of the DG 21*9 brand, the minimum opening should be 2.160 m in height and 0.980 m in width. This principle applies not only to doors installed in partitions, but also to all similar structures in general.

• Since the plasterboard partition is frame structure, then the opening in it is formed at the time of installation load-bearing elements. Can be used for production wooden blocks, but more often, aluminum profiles are used for this purpose: guide and rack. Its dimensions are selected depending on the dimensions of the partition and the weight of the door being installed, for example: PN75/40 and PS75/50.

Partition frame

• First, the perimeter of the future partition is drawn on the floor, ceiling and walls, along which, with the back facing base surface, the guide profile is mounted. Its shelves form a groove into which they will be inserted vertical racks and jumpers. Before installing the lower guide, it is necessary to mark the location of the opening on the tapping line, because the profile is not attached there.
• Of the vertical load-bearing elements, the first to be installed are those that form the doorway. The distance between them, as already mentioned, should be 8-10 cm greater than the width of the door with the frame. Then, between these two racks, a crossbar is mounted, which will limit the height of the opening.
• They cut it out from the PN profile and install it so that the shelves are turned towards the ceiling. Depending on the method of installing the gypsum board around the door, one or two short intermediate posts will be inserted into it, giving rigidity to the opening. For the same purpose, wooden blocks of the appropriate section are inserted into the groove of the side posts, to which the box will then be attached (see).

Everything is ready to install the door

• What the partition frame looks like can be clearly seen in the previous photo. How to cut a profile correctly, how to do it by bending the fastening, what distance should be between the frame elements, and other necessary information, look for in articles specifically devoted to this topic, as well as by request: “Preparation doorway video".

We only talk about this in general outline, since the article is devoted to the process of aligning the opening. Although there is nothing to level in plasterboard partitions. Usually the thickness of the partition is made in accordance with the door frame.

If no mistakes were made during installation, all that remains is to putty the surface of the walls adjacent to the frame, finish them, and cover the joints with platband.

Forming a smooth opening

Repairing openings in the bathroom, or near it, which will be discussed later, is a completely different matter. In these places plasterboard partitions does not happen, but there are quite thick load-bearing walls.

The front door opening is often filled with one frame with two panels or several bindings. This is justified by the fact that one door, for example, can be metal, and the second wooden.

The space between them is called the stub. Considering that the thickness load-bearing wall can be quite impressive - say, two bricks (51 cm), it is natural that even a double binding does not completely fill the opening. Most often, the door is placed flush with the wall on the outside, and slopes are created on the inside.

Slopes can be plastered and thus get rid of curved surfaces. Then everything needs to be puttied

Sometimes they are covered with wood or MDF, but most often they are plastered cement plaster. In any case, after replacing the door, or during a major renovation of the walls, when the plaster needs to be knocked down to the base, the geometry of the slopes is significantly disrupted, and you have to think about how to level the opening.

Methods for leveling slopes

Now we have come to the most difficult stage of wall repair. By the way, invited craftsmen charge separate money for plastering slopes, and the price, I must say, is rather high - about 250-300 rubles per linear meter.

Thus, the slope of one door measuring 2.1 * 0.9 m will cost at least 1,300 rubles. Although, such work may not take too much time - it all depends on the initial state of the opening.

• Try to do it yourself, especially since you can use a variety of available materials for the work. Aligning the side walls of an opening without a door is carried out according to the same principle as plastering rectangular columns. On the sides of the slope, checking the level, two long aluminum rules, extending them beyond the plane of the surface to the thickness of the plaster.
• Rules, in in this case, serve as beacons, but in principle, you can do without them. The role of rules is just as successfully fulfilled regular profiles for drywall, which are mounted on self-tapping screws or dowels, with their backs facing the side surface of the opening. Just like the rules, they need to be moved forward by the thickness of the screed.

• If there is a door in the opening, then the beacons are mounted only on one side. In the first case, excess mortar is removed with a short rule, a small spatula, or a wide spatula. If there is a door in the opening, you need to make a template from scrap materials, which is shown in the picture above.
• It can be made from a piece of plywood, hardboard, plasterboard or even thick cardboard. The main thing is to make a recess on the template that exactly fits the protrusion of the door frame. This will allow you to make a clear line of the plaster layer around the perimeter of the door. After the solution has set, but has not yet hardened, the beacons are carefully removed and a corner is formed, cutting off all excess with a spatula.
• When the leveling screed, which is made with a base mixture with a coarse dispersion of components, has dried, a plaster layer is installed over it. perforated corner. And then they putty. If there is no major damage on the slopes, then thick layer no need to apply plaster.

• In this case, you can do without beacon profiles and install the corner straight away. By the way, when plastering walls and slopes with specialized mixtures, you can simplify the leveling process by using the same drywall. If you cut long narrow strips and glue them onto putty along the uprights of the box, you will get a perfectly even junction.
• Aligned in level, these strips will serve as beacons for applying a leveling layer. There is no need to remove them, since after the starting layer has dried, the strips of drywall will be hidden under the putty. By the way, it is also more convenient to level the upper slope with plasterboard.

Plaster mixtures, especially when a thick layer has to be applied, do not adhere very well to horizontal surfaces. You have to install the mesh, apply several layers, and each time wait for them to dry.

A wall plasterboard itself has a thickness of at least 12 mm, plus a thick layer of glue, which allows you to level the slope in one step.

Openings where there were none

Sometimes, when major renovation or redevelopment of apartments or houses, the owner decides to change the size of the opening. If the walls are load-bearing, such actions are preceded by obtaining permission; if it is just a partition, then the housing commission is notified of the fact of the work performed. But that’s not about that now.

Passages are made different ways, the choice of which depends on structural material walls. Accordingly, slopes are formed in different ways. In brick, foam concrete and asbestos-cement partitions, passages are cut. These materials are quite soft, so high costs cutting the opening is not required.

Naturally, this is done according to preliminary markings, after which leveling and finishing are carried out. If the passage just needs to be widened, it is easier to do it on only one side. Although, the layout does not always allow you to do what is easier, and you have to cut the opening on both sides.

Cutting and strengthening

Diamond cutting of openings, performed using specialized wall-cutting equipment, although more expensive, can solve the problem of a structure of any thickness and strength.

So:

• At the same time, there is no dust, since such equipment is equipped with a dust collecting device. Dirt, of course, happens, but because the working blade of the wall saw has to be cooled with water during the process. But with such equipment, everything is done exactly to size, quickly, and without unnecessary noise.
• Since the cutting process violates the integrity of the structure and removes a fragment that took on certain loads, the openings are necessarily reinforced with rolled metal. IN curtain walls The perimeter of the opening is tied with a steel angle of 40*40 mm and connecting plates.

Gain

• IN multilayer walls- For example, frame houses, amplification is carried out square pipe, embedded inside the surface and fixed to the ceiling. For half-brick partitions, a channel is selected the right size, mounted U-shaped on both sides, and attached to the ceiling and floor.
• In general, reinforcement options can be different, and they are determined by the project, without which such work cannot be carried out (see). Reinforcement of openings is also carried out in cases where the strength of the structural material of the wall is insufficient to withstand, for example, a steel door.

Arched passage with polyurethane frame

Whatever the finishing of such openings, their slopes must be plastered with cement plaster. To hide metal structures, you have to apply a thick layer of mortar, and this must be done over a coarse-mesh steel mesh, mounted on the surfaces of the opening.

After the plaster has completely dried, the opening can be lined with polyurethane stucco - and no one will guess that there are metal structures underneath.
