Stick with a punch with your own hands in concrete. Which tool is better
DIY wiring for wiring
This procedure is carried out quite often, the stroke of the walls for wiring can be carried out with your own hands, the main thing is to follow the rules I have indicated.
Often as part of the repair work, wiring is replaced in the house. Since modern cables cope with all requirements, withstand the load from the abundance of various equipment and meets rigid norms.
New wires are laid in the walls. This is a measure of safety and preservation of the design of the room.
It is necessary to know how the strokes are carried out under the sockets, under the cables, and for the sewer. In the ceiling or wall surface, in.depth channels of standard parameters are created in them and wires are placed.
Norms and restrictions when strokes of walls for wiring
There are regulated standards that need to follow. They are reflected in SNiP 3.05.06-85. Their list is as follows:
- The maximum depth of the strobe is 2.5 cm, width. 3 cm, length from the grocery box to the outlet of the light device. 3 m.
- Stroke under cables can only be in a vertical or horizontal vector.
- Paragraph 2 excludes the walls from the attic, since they have an inclined position. They are stripped in parallel in relation to the slope of the roof.
- On the wall surface, the minimum distance from the floor slabs is 15 cm, 40 cm from the gas pipeline and batteries, 10 cm from the window and door.
- Electric wiring should have a minimum of bends. I recommend that they exclude or allow one turn at an angle of 90 degrees.
- Shtroting is prohibited in places such as: corners of the room, carrier walls, floor slabs.
- Due to the formation of large volumes of dust, protection is required: respirator, glasses, mask, etc.D.
Prior to the start of the operation, paper displays a diagram with the installation sections of all points and circuits of the planned laying.
DIY wiring for wiring is accompanied by increased noise. The walls begin to vibrate, and this is given to all neighboring apartments. For this reason, carry out such operations on weekdays from 10 am to 5 pm.
Methods of stroke of walls for wiring
Hammer and chisel. grandfather’s tools that will allow you to spend a minimum of money on stroke of walls. Minus. the strobes will be crooked, and the process itself. very long. It is difficult to imagine that a hammer and a chisel make grooves for all wires in the apartment.
The process itself is quite simple, you can cope without special preparation. First, the chisel with a wide side is applied to the intended line and hit with a hammer. Thus, the edges of the strobe outline. Then the chisel put across the grooves and begin to knock out the recess in the wall. You can outline the boundaries of the strobes in a certain section, and then “dig” into the depths, or you can “delve” after each pair of centimeters of the borders made.
The strob lines will be uneven, but later they will still be hidden under a layer of plaster and finishing. You can get more even edges if you make the tiles in advance with a hacksaw.
Hammer and chisel is the longest and laborious way of stripping walls. It is suitable if there is a need to extend the existing highway, and you don’t want to call a master with a stroberase anymore.
For concrete and brick walls, this method is useless.
Peorator or shock drill
Both tools allow you to quickly post the walls, but the edges of the grooves will be uneven. Shock drill and peorator. not the same. The shock drill makes holes through rotation, the peorator. through a blow. In the drill, the blow is weak, but with a high frequency, the penetrator has a stronger blow, does not require any help from a person. The drill will cope with concrete and brick, but not intended for frequent drilling with a blow. The pedorator is much more powerful, the concrete and brick of any density will be able to hammer it, because for stroke it is a priority.
- with a drill at a distance of 1-1.5 cm from each other, make recesses along the entire highway;
- Replace the drill with a shoulder blade and clean the groove at an angle of 45 degrees, passing from point to point. Use the “without drilling” mode;
- It is better not to put a wall of the wall across the wall, otherwise you can break a piece of the wall;
- If only a drill is at the disposal, then take a winning drill with a diameter of 8-10 mm. The distance between the holes is less-0.5-1 cm. If you need a wide strob, make the holes in a checkerboard pattern. The gaps are knocked out with a hammer and chisel, as described above. This method is suitable, if necessary, for example, to make strobes in one room. If the task is to conduct wiring in the entire apartment, then it is better to invite a specialist. Residents of Kyiv and the region can contact Relicon, on the HTTPS: // Relicon page.Kiev.UA/ Elektromontazh/ can be found with the list of services, and advantages. The company’s specialists carry out both whole projects and individual electrical work.
Methods of stroke
There are four main ways to make grooves. Their main difference is the use of the tool and the application of the use of this technology.
- A hammer and a chisel. The disadvantage of this method is the inconvenience of work “grandfathers” tools. Even with good dexterity, it comes out for a long time and with crooked highways. A huge plus can be called the cost. it’s cheap definitely.
- Shock drill (peorator). Minus. strobe with uneven edges. Pluses. process speed and relative cleanliness during operation.
- Corner grinder. Cons. a large amount of dust, which is difficult to assemble even a construction vacuum cleaner. Plus. even recesses in a short period of time.
- Strobores. Minus. the high cost of the tool. For one.time use it turns out too expensive. Pluses. fast, not so noisy, even edges of the stroke, without dust.
Preparation and marking of the working surface
First of all, it is necessary to check the walls for the old wiring. To do this, there are special testers and indicators, the principle of which is based on the overall electricity scheme. It looks like this. from a common circuit to an electric point, for example, two wires are suitable for an outlet. phase and zero. On the phase there is a current from the chip to the point constantly, regardless of whether something is connected there or not. The zero wire is voltage only when the device is turned on. And only then is the current return back to the switch. Indicators catch a phase wire. In many indicators on top there is a special light bulb, which lights up when the target is found. This stage of preparation is necessary to protect yourself from electric shock.
After the check, you need to draw the future route on the wall. from the camshaft to each connection point.
Before starting work, be sure to cure door openings with a damp cloth or building film. Do not hope on a tightly closed door. small particles of dust will still find a loophole.
Features of work with various materials
In the presence of a correctly made scheme and suitable tools, it is easy to carry the walls of the walls even to a newcomer in construction. But this is if the wall is not carrying and covered with a thick layer of supple plaster.
But what if the internal partitions are made of concrete of increased strength, light aerated concrete or even wood? Consider the nuances of working with various materials.
Strobs in concrete and brick
On a brickwork, fastened with a mixture of sand with cement, you can hide horizontal grooves even with a chisel and a hammer if you “get” into the seam. For vertical stroke, it will be better to use the power tool. an angular grinder, a peorator, or a strobore.
If the masonry is closed by plaster, you can cope with primitive manual equipment, however, the process will take a lot of time.
Rules for marking the stroke for wiring on brickwork: horizontal channels are knocked out at the junction of rows, vertical. between rows of bricks
In principle, there is nothing complicated in working with concrete. even though the material is quite durable, the grooves on it can be made by any tool suitable for stroke, except, perhaps, a hammer and chisel.
But the best choice will still be the peorator, although the evenness of its grooves leaves much to be desired (however, all the nuances will correct the plaster).
The level of noise from the peorater exceeds 60 dB, and in order not to injure neighbors, it is allowed to perform work with it only on weekdays and in the daytime, taking periodic breaks for 1-2 hours
This shock tool has high power, so it will cope with any hard surfaces. He does not form such a large dusty cloud as an angular grinder, and does not require an additional tool to prove the remnants of the material inside the furrow.
The peoporator and drill are suitable for the formation of round holes, though the master will need experience: for this:
Before drilling a round hole in the wall with a with a pen or drill, we mark the socket directly to the installation site
According to the marking of Burim points with a step of 1-1.5 cm, better even less. The more often the points are located, the faster and more accurately the hole will be formed
We combine in a continuous circle drilled along the contour of the point. Then, with the same nozzle, we achieve the necessary depth of the recess
After reaching the necessary depth, a hammer and chisel enters into battle with a “. All superfluous must be banally chopped off and remove
In addition, on concrete walls of increased strength, use a corner grinder (and its analogues. a circular saw, an angular grinder) is unsafe. with a strong pressure, the circle may break.
How to work with wood and aerated concrete
You can make grooves in the walls of aerated concrete or foam blocks using corner grinders, drills, peorator or circular saw. But if you want to minimize the amount of dust, use a special manual strooborean designed to work with supple material.
Its pointed arc easily cuts out a neat groove, and the desired depth can be achieved in just 3-4 passes.
By the way, it is easy to make such an instrument with your own hands from a plate imprisoned on one side or a hard peaolent. To do this, you need to bend an arc of a small segment of improvised material and fix the edges with wire or island.
For small volumes, such a device is quite enough, but if you need to conduct a network of channels with a total length of more than 20 m, it is worth equipping the device with a comfortable handle from the pipe.
As for the walls from a profiled timber or a gallected log, then, according to fire safety rules, the installation of open electrical wiring is recommended here so that in the case of force majeure it is possible to quickly neutralize the source of ignition.
In extreme cases, for wooden walls, you can use a special milling cutter, a corner grinder with a circular wood disk and a chisel, with which you can remove the material between the tiles.
But, we repeat, it is better not to risk camouflage wires and perform installation without violating the standards of the PUE and the integrity of the wooden coating.
Nuances with load.bearing walls
As already mentioned, it is forbidden to stroke the supporting structures. if the upper layer is damaged in the wall, the reinforcement is exposed, as a result of which corrosion may begin, which will weaken the entire frame of the building. But what about the owners of apartments in the house where part of the partitions are made of reinforced concrete or most walls carrier?
- Official approval. to obtain permission to carry out work on a posting in the local construction department. You can try, if you prove that the depth of the grooves will not affect and does not damage the reinforcing mesh, the deformation of which leads to the begging of the supporting structures. But if we are talking about a panel house-the chances are almost zero, but for a frame-brick building, permission will most likely be given.
- Apply a plaster layer to the wall and carry out a stroke without delving into the design of the slab itself. Typically, the reinforcement lies under 1.5-2 centimeter layer of concrete, therefore, if you level the wall with a plaster mixture, the depth of the grooves will not affect the metal.
And the last way to help solve the issue with any problem wall is to hide wires behind drywall or in special electrical skirting boards.
Phased description of the process of stroke
First you need to draw up a diagram with a detailed indication of all elements of the electromagistral. Those who are friends with a computer can use special programs, for example, “Compass Electric”, ProfiCad, Qelectrotech or other graphic editors.
In specialized programs, you can draw various plans and installation circuits for electrical wiring, however, it will be difficult to figure out the non.professional, so most use a simple drawing on paper
The step.by.step process of stroke of the walls by wiring:
- If possible, protect the room from construction debris. close the doorway with a damp cloth, carry out furniture and equipment or tightly close.
- If there are wallpaper on the walls. they need to be removed so that pieces of paper do not get stuck in the power tool.
- Then we transfer the wiring scheme to the walls, using the drawing, a marker and the construction level drawn up in advance.
- We check the placed zone for the presence of an old wiring with an indicator or metal detector. if one is found, it will be necessary to dismantle it or do not less than 10 cm. Ideally, the apartment should generally de.energize and stretch the wire to the neighbors, because if you accidentally stumble upon a cable missed during inspection, you can get a serious injury.
- Now you can make strobes using protective equipment and any tool that is convenient for you suitable for wall material.
- When the entire track is made, the grooves must be cleaned from the remnants of the material and dust, then treated with a primer in deep penetration.
- When the impregnation is dried, you can mount the wiring.
Keep in mind that the strokes are different, because the grooves are intended not only for the cables themselves, but also the masking of sockets, switches and decaying boxes.
Usually, the boxes themselves are placed immediately under the ceiling (in the place where the main electric mass of the rod passes), and the sockets with an indent of 30 cm from the floor level. And for them you will need to make a recess in the form of a circle.
Prepare the “crowns” of two types. 80 and 65 mm, with which round holes are cut for a camshaft and sockets
Of course, you can manually remove such strokes for the installations of sockets, outlining a fishing line for a trimmer with a drill or chisel, but it is much more convenient and faster to do this using a peorator and “crows” of a suitable diameter. The same nozzle can be made for the recess for switches.
Choosing a tool for work
Strokes of walls can be performed by different tools. It can be a chisel with a hammer, a corner grinder or a peorator with certain nozzles or a specially designed trobrebore. When operating the last device, you run the risk of serious financial costs, but the grooves made will be perfect.
The choice of a specific tool is associated with individual preferences of the master and owners of the house, as well as the capabilities. Ideally, this should be a quality tool that allows you to create an even bar, which will exclude potential remake.
Chisel and hammer
For a concrete wall, a hammer with a chisel is absolutely useless. This is a very strong material, therefore the walls will be so strong that a manual tool simply does not break through them. But for a brick wall, a hammer and chisel will be almost the best option.
Guide the following scheme of work:
- Mark the recesses, indicating both edges of the future groove.
- The chisel should not be installed along, but across the strobes, and then gradually drive into the wall with a hammer.
- The strobe deepens in layers by 20-25 mm.
After the stroke of the walls is completed, you need to clean the resulting grooves. Cover the surface of the stroke with special soil. When it dries, wires are laid in the ditch, then you need to hide them under a layer of plaster. It is dangerous to use a chisel and a hammer for trinification, since a certain work skill is required. Independently perform this procedure by modern and professional devices.
Corner grinder (angular grinder)
Another no less popular tool used to stroke walls is an angular grinder. There are no special difficulties in operating the device. First, prepare a disc with special diamond spraying. Such a canvas is required if the wall is made of concrete. The diamond disk is characterized by high strength and durability, due to which the process of strokes proceeds much faster.
To begin with, cut the corner grinding with two stripes along the wall area along the marked lines. These slots should be placed parallel to each other at a distance of about 20 mm. But one corner grinder is not enough: after the slots, you will need to use the peorator to get rid of the part of the wall that is located between them. Then you can immediately lay the wiring in the resulting strobes, and then close them with plaster.
Advice! The depth of the grooves is selected so that the process of plastering does not cause discomfort and inconvenience. Hiding the wire under the finishing layer to good depth, it will be easier for you to finish the walls.
Other alternative tools, for example, drill can be used for strokeing walls for wiring. We’ll have to take a thick drill installed in the cartridge, and drill several holes in one row at a certain distance from each other. The depth of each hole is up to 20 mm, so much time will not take. For simplified control of the depth of holes on the drill, you need to stick a strip of color tape, which will not have to go into the wall. Stop drill in advance before the strip reaches the wall.
From the holes located in a row, you need to create a solid strobe. To do this, a chisel with a hammer or corner grinder (corner grinder) are suitable for this.
When operating the pedorator, the maximum savings of financial resources and time are achieved for making a stroke. The preparatory stage is the same, regardless of the chosen tool, and the implementation of the stroke is as simple as possible. First, make sure there is no old cable. If the detector finds the wire, then it should be removed by previously disconnected from the distribution box.
Further, the wall is made: the lines indicating the location and direction of the bar between the camshaft and sockets. Doors and windows need to be curtained, and the gaps between the boxes, door or window canvas. plug a moistened rag.
Using a peorator, drill several holes along the marked area. The distance between each hole should be up to 15 mm. In principle, the process is no different from the use of a drill, only the peorator is a more reliable and powerful tool. Then the peorator is switched to the second operating mode used to create a stroke. For this, the working nozzle is changing. In this mode of operation of the penetrator, all holes are interconnected, while a whole ditch is obtained.
Important! Do not try to carry out the stroke directly, without making holes. Such work is by the power of professional and experienced craftsmen, and for beginners it is recommended to make holes.
The overall drawback among all the listed tools used to stroke the walls is a huge amount of dust that stands out during their operation. The dust layer can reach large sizes, which is why you cannot completely clean the room even when using special equipment. If you want to observe a high level of cleanliness when performing work, we recommend that you use a strobes. a tool specially designed for such procedures.
Externally, the device looks like a regular angular grinder, but it is equipped with special diamond discs. The device works using a casing used to regulate the thickness of the future groove. You also need to monitor the depth of the stroke. Strobores connects to a vacuum cleaner, which delays all the allocated dust, so that the room will preserve cleanliness.
Specific features of stroke
Next, we will consider in detail the stroke of the walls from different materials.
How to make strokes in wood
For wooden walls, all of the above tools are suitable with the exception of the peorator. Instead of a chisel, it is better to apply a chisel, but the principle of work remains the same. Create two parallel cuts at the same distance and remove the wood between them using a chisel. specific tools can also be used:
- The circular saw allows you to make even strobes, but a high skill of ownership of the device is required. The principle is based on repeated passages with circular and gradual expansion of sawing to the desired width.
- A handmade cutter allows you to create a neat groove. To do this, they attach a guide bar to the wall and a tool is carried out along it, making an even deepening. Then it expands to the desired width. For such work, a special cutter is often used, but you can cope with the usual nozzle forming the groove.
Thus, tools for stroke of wood are greater, as well as the ability to do this. Ideally, you need to choose one of the listed tools, since they are designed for wood work.
How to make grooves for wiring in aerated concrete
Ideally, you should use manual trobores for aerated concrete, since blocks are easily lend on such processing. The tool is a metal tube with a handle and a protrusion on the other side. It is simply in use, leaves behind a minimum amount of dust. Alternative. the use of a circular saw or corner grinder angular grinding, but you will need good protection for the respiratory tract.
There are certain nuances. Walls from aerated concrete or foam concrete blocks often contain reinforcement, so the process of their stroke requires a special approach. Before making the recesses, make sure that your actions will not lead to a decrease in the strength and integrity of the structure.
If you need laying wiring in the house without finishing on the walls, then usually they do not engage in stroke. Instead, a flat cable with the desired section is installed on the brick wall, after which it is hidden under a layer of plaster with a thickness of 30 mm. This is enough to hide the 3 × 2.5 or 3 × 4 cable. A larger wire is used much less often.
Strokes of walls, if necessary, are carried out by any of the listed tools. The process is identical to the creation of recesses in concrete walls. However, the brick is softer and better lends itself to processing.
Hypsum cardboard stroke
Drywall sheets are very thin, so it is impossible to make strobes in them. Typically, the cable is hidden under the fragile structure of the sheet, and the only option could be drilling the holes necessary for installing a socket or a seat under the circuit breaker. This is done using a peorator.
Strob in the tile
Tiles are often used as a finish in the bathroom or in the kitchen. Often there is a need to make a stroke in the wall. And there should be no problems in this regard: the only nuance. it is required to install special diamond circles on an angular grinder or a strobore. To exclude the formation of cracks in tiles, avoid the use of the penetrator.
Nuances with load.bearing walls
Before performing the repair associated with the laying of a new or replacing the old electrical wiring, you need to draw up a project. Entertaining documents will be required, which indicate the location of the load.bearing walls and the possibility of making depressions in them. The resulting plan clearly indicates where, where and how to lay a cable, what width and depth should there be strokes, etc. D.
If you have doubts about the appropriateness and admissibility of making a stroke in the bearing wall, then try to get the appropriate permission in BTI. The organization engaged in the design of the house will provide all the documents and clarify the margin of strength of the building. The resolution will be issued in most cases.
Stroke of walls for air conditioning
Particularly dimensional cables are required to install standard air conditioners consisting of internal and external blocks. The width of the strobe should be at least 60, depth. 50 mm. This will allow hiding all copper tubes with insulation materials, wires and corrugation used as a removal of condensate.
Is there any dusting without dust
The dustiness of the air in the room where the stroke of the walls of concrete is carried out is one of the problems that has to be solved in the process of work. Therefore, the question is. is it possible to stroke without dust worried many who have come across a similar problem. I must tell them that this is quite possible. The problem of air dust is solved if you use a specialized strobes and an industrial vacuum cleaner. For the effective removal of dust, the vacuum cleaner hose is connected to the pipe of the removal of cutting products of the power tool.
In the first place among issues that excite owners, undoubtedly, is the problem of strokes of the carrier wall for wiring. In GOST P50571.15-97 states that when laying hidden electrical wiring, the strength qualities of structures should not decrease. In the ladies of the panel type in monolithic panels acting as bearing walls, cutting grooves only plaster is allowed so as not to weaken the strength of the panel. On other load.bearing walls, it is allowed to make horizontal strip routes up to 10% depth and vertical grooves with the condition for maintaining the integrity of vertical reinforcement.
Do I need to carry out work before plaster
Until recently, no PUE was indicated in any publication, how should it be correct, first plaster, and then wiring or vice versa. But in the recently updated set of rules, work on plastering was mentioned. It, in particular, states that by the beginning of the finishing work, the entire electrician must be mounted. It turns out that according to the standards, to correctly engage in electrical wiring before plaster.
However, according to electricians, it is better to start laying the wiring after plaster, and not before. Especially in panel.type houses, it is allowed to lay a strobe only in plaster. Another reason for the preference of this order of work is the use of water when plastering walls. And if the first thing is to conduct an electrician, then it is necessary to protect the joints of the wires in the sockets, which is not always possible to do.
Hammer and chisel
A hammer and a chisel are used to manufacture a bar in soft materials, one of which include almost all types of plaster.
To stroke the wall with the help of a hammer and a chisel, you must take a hammer in one hand, and in the other chisel and, having put a chisel to the desired place, hit it with a hammer, as a result of which a pothole will appear in the wall.
Thus creating potholes and expanding them in the right direction and size, you can create a stroke.
The dimensions of the sednett, such as the depth and width are determined by the sizes of the cables, but they cannot exceed 30% of the width of the wall.
DIY wiring in the kitchen
If you believe statistics, it is in the kitchen that from 30 to 50% of the entire “apartment” technology, that is, electrical devices, is concentrated. All of them should be provided with nutrition, but in practice it often happens that existing power networks do not withstand such a load. It turns out that the wiring in the kitchen should be performed by the owner independently. taking into account all individual requirements.
You can do some of the work with your own hands. but only if you have experience.
As for the preparatory processes, including the preparation of the electrical wiring project, only the owner can do this. in any case, the part where the total capacity of the equipment must be calculated. This will determine how many sockets are needed in the kitchen, and also understand how they need to be arranged correctly.
Preparation for work
The wiring in the kitchen requires a mandatory compilation of the project. In order for it to be correct, it is necessary to determine which equipment is planned to be placed in this room:
The kitchen also often decides to arrange a TV and a washing machine. and each unit of equipment needs its own outlet.
Tip: you should purchase sockets with a margin and carefully think through the location of the equipment, so as not to get confused in wires.
But just calculate the equipment for drawing up the electrical wiring project will not be enough. Further, work is carried out according to this algorithm:
The type of network entering the apartment is determined. In the case of single.phase, the total power will be very limited, in the case of a three.phase, wiring in the kitchen can be created with a tangible supply of power.
9 YEAR OLD ME AFTER WATCHING SPIDER-MAN #Shorts
As a rule, three.phase wiring in those rooms where an electric furnace is installed.The total power of kitchen devices is calculated. for each device, the rated power indicated in the technical passport is taken. The value should turn out to be 8-15 kW (while turning on all devices). Of course, in practice, all devices are rarely turned on at once, but it will be correct if the wiring is created with a power supply.
A cable is selected to create electrical wiring.
It is better to use reference data or entrust the work to a specialist. As for general recommendations, they are as follows: the higher the total power of the device, the thicker the electric cable should be. For example, with a total capacity of 11 kW, a copper wire with a 6 mm section will be required, and a 10 mm cross section needs a 10 mm cross-section.
Than to stroke brick walls
Brick. artificial stone used for the construction of different objects. It is made of quartz sand, burned cheesecakes, unbroken clay or overwhelming lime rocks. Differs in appearance, shape and characteristics.
Regardless of the material used, the brick walls are difficult to curtain, therefore, to perform work, it is recommended to use a professional tool.
With a shit, it is necessary to be careful, because the brick has the property crumbled, so you can’t do without protective glasses.
Not big life hack. the use of a drill on ceramics and a screwdriver. The bottom line is to use a drill on ceramics as a milling cutter, t.e. Use side edges for stroke brick.
Channel stroke occurs very quickly and without dust. Especially this life hack is suitable for silicate brick.
Than to stroke a monolith
Monolith. a popular building material used in the construction of different objects. Its peculiarity is the use of metal reinforcement and concrete, which is poured directly at the stage of construction of the facility.
This technology has gained popularity due to the low price and high strength of the finished reinforced concrete structures.
Things You Will See for the First Time in Your Life. Part 9
A lot of issues concerns the resolution for stroke in monolithic walls.
- GOST r. 50571.15-97 permits the wiring if the work does not affect the functional features of the object;
- SP 31-110-2003-it is allowed to install hidden, but not tattered wiring.
It is forbidden to make wiring in concrete columns, external walls and elevators of elevators.
The monolith of granite is especially difficult, so in this case it will be better to turn to professionals.
How to mask the strokes with wiring
Decorating the stem is usually performed with:
- The furrow is cleaned of dust using a vacuum cleaner or other improvised means.
- Grind the brush abundantly with a primer, and close up the recess. Do not regret the funds so that later do not have to redo the work.
- When a primer layer dries, the groove should be slightly moistened with water.
- Seam the seam in the wall with any decorative material.
Tips and recommendations
The advice of the masters will help to conduct high.quality and quick stroke of the walls:
- If you need to connect 2 points, then it should be remembered that in this case there can only be one turn in this case.
- Before work, it is necessary to clean the walls of wallpaper, dirt and garbage.
- During the work, you need to constantly check the size of the future strobe.
- The load.bearing walls cannot be touched inside, but it is possible from the outside. On the first floors of work should be carried out with marginal accuracy.
Strokes of walls with the involvement of a professional can cost the owner a round amount. It is more profitable to engage in this process on your own, having prepared the necessary tools and materials in advance. Everyone can carry out the tables of walls at home with their own hands, if you carefully follow the instructions and follow the rules.
