Make a dust-free angle grinder

What is this process for??

Most often, the main purpose of the chasing is to give the room an aesthetic appearance, so that the wires and other communications are hidden in the walls and do not look out.

Therefore, in modern apartments, chipping walls to hide wires and pipes in them is one of the mandatory works when performing repairs.

However, in addition to the aesthetic appearance, chipping the walls in rooms helps to use their area correctly, through a convenient and rational arrangement of openings, furniture, and other household items.

Features of the work, depending on the material of the walls

A feature of slitting in concrete is that concrete has high strength.

When making grooves in a load-bearing wall, special attention should be paid to the fittings that are located in the wall. Damage to it must be avoided, as this can lead to metal corrosion and possible weakening of the supporting structures. In order to prevent damage to the fittings, you need to use a metal detector.

In addition, when chipping the load-bearing walls of panel houses, it is strictly forbidden to do horizontal slitting, since the load-bearing panel is constantly in a stressed state and any reduction in its cross-section can lead to the collapse of the floor panel and even the whole house.

If, nevertheless, the need for grooving cannot be avoided, then grooves on load-bearing walls should be placed only in the vertical direction, which corresponds to the direction of the stiffeners of panel structures.

When chipping the load-bearing walls of panel houses, you should make as few recess folds as possible, and the channel length should not exceed 3 meters.

Certain features also exist when chipping walls made of silicate bricks. Silicate brick is inferior in strength to concrete, and therefore it is easier to make grooves in it.

The peculiarities of chipping walls made of silicate bricks include the fact that when chipping one should take into account its natural properties, such as increased moisture absorption and susceptibility to aggressive environments.

Moisture, in case of contact with a brick, worsens its thermal insulation properties, and the aggressive media present in the soil can lead to a reaction with the lime base of the brick and its destruction, as a result of which the entire building can be destroyed.

In this regard, when chasing walls made of silicate bricks, special attention should be paid to ensure that the chases do not come into contact with source of moisture and open soil.

Than the walls are chased

The standard arrangement of lamps or sockets does not always suit the owner of the apartment. In this case, the question arises about their transfer to another place. To do this, it is necessary to make grooves or holes in the walls or ceiling. In multi-storey buildings, they are made of concrete or brick. Therefore, if it is necessary to groove the walls for wiring, it is better to take care in advance in order to avoid a large amount of dust.

You can make the grooves in the wall manually, but if you need to lay a long cable, this will take a lot of time. Therefore, it is better to use a power tool. For work of this kind use:

  • perforator,
  • Angle Grinder,
  • wall chaser,
  • impact drill,
  • chisel and hammer.

The use of a hammer drill has a number of disadvantages. First, the instrument makes a lot of noise. Therefore, if work is being carried out in a residential building of a high-rise building, you will have to negotiate with neighbors. The process of chipping with a perforator is quite laborious and time-consuming. In addition, the resulting indentations have an uneven edge. A traditional “angle grinder” with a diamond disc produces holes with a good edge, but the grooves themselves have an uneven surface. This creates the risk of damage to the wiring, in addition, too much dust is generated in the process.

The ideal option would be a wall chaser. With its help, you can quickly and easily make holes and grooves for an electric cable. This tool cuts with two blades. They are insulated with a casing that covers the point of contact with the surface. This makes it possible to punch furrows of different depths. The strobes are smooth on the inside, and their edges remain even.

In the absence of a power tool, you can also make a strobe manually. For this purpose, a chisel and a hammer are used. This technique is not suitable for hard materials such as sand-lime brick or concrete. With the help of a chisel, a groove is punched in the wall, which is then deepened and widened. At the same time, the tool is held in the right hand, parallel to the surface, and hit with a hammer.

Tips on how to gouge walls for dust-free wiring

Any master knows that when replacing wiring in an apartment, you have to make holes in the walls. The resulting construction dust settles throughout the room. Is it possible to facilitate the process of work and subsequent cleaning?

A few tips on how to carry out dust-free chasing will be useful to those who are starting a repair.

How to get rid of dust when chipping

Professional builders use equipment with a built-in vacuum cleaner when laying wiring inside walls. But the cost of such a tool is high and it makes no sense to buy it for a one-time event. In order to grind a wall with a wall chaser without additional options, without creating a cloud of dust, craftsmen have to go to different tricks. The simplest way is abundant wetting of the treated surface with water. Small particles can be collected with a simple household vacuum cleaner.

To grind the angle grinder without dust, use the technology of wet cutting of concrete. It consists in the continuous supply of water to the cutting disc through the attached hose. You can use the help of an assistant who will simply water the disc and the cutting area from a plastic container. In this case, you should be careful not to get any liquid on the power tool.

The following measures will help to reduce the dustiness of the room:

  • the floor is covered with foil,
  • an industrial curtain or fabric is fixed above the entrance,
  • put a wet rug in front of the door.

After the strobes are done, the debris is swept away with a broom and vacuumed. The deepening is treated with soil, the cable is laid and fixed. The channel is sealed with putty, plaster or plaster.

You can run electrical wires without chipping the walls. This option is attractive due to the complete absence of dust. The trade network contains many different products that allow not only to disguise open wiring, but also to revive the design of the room. These include:

If there is a need to replace the wiring, without laying a new one, you can use the existing channels.

Small particles of concrete and sand-lime bricks should not enter the mucous membranes or the respiratory tract. Therefore, when carrying out work, it is necessary to use protection in the form of glasses and a respirator. If there is furniture in the room, it is also better to cover it with a film or cloth.

Almost everyone who has decided to start repairing their apartment, summer cottage or house is faced with the need to cut walls.

This part of the repair work is carried out in the event that during the repair it became necessary to carry out new electrical wiring or replace the old one, lay pipes and other communications.

Do-it-yourself wall slitting methods

The methods of wall chasing depend on the tools used when making the chase. Let’s take a closer look at how you can grind a wall.

Chipping tool:

  • puncher;
  • Angle Grinder;
  • wall chaser;
  • hammer and chisel.

Hammer and chisel

A hammer and chisel are used to make strobes in soft materials, which include almost all types of plaster.

To chisel a wall with a hammer and a chisel, you need to take a hammer in one hand, and a chisel in the other and, putting a chisel to the right place on the wall, hit it with a hammer, as a result of which a pothole will appear in the wall.

By creating potholes in this way and expanding them in the desired direction and size, you can create a strobe.

The dimensions of the grooves, such as depth and width, are determined by the dimensions of the cable or pipe, but cannot exceed 30% of the wall width.

Wall chipping for air conditioner

For a household air conditioner with two standard blocks. an indoor and an outdoor one, special dimensions are needed for the strobe. The minimum width should be 60 mm and the depth 50 mm. Such dimensions will make it possible to place the entire “filling”, consisting of two copper pipes with insulation, two wires and corrugations for condensate drainage without damage.

Specific features of slitting

Sometimes you have to deal with non-standard situations in which you need general knowledge and a little more advice. Among the most common were selected below.

Making a furrow for concrete

To lay a gutter in a concrete wall, it is better to use a chasing cutter, a puncher and a chisel. At the same time, be careful not to disturb the reinforcement that is inside the slab to strengthen the structure.

When working on a concrete wall, a large amount of dust is emitted. Therefore, you can use the hammer drill, operating it in percussion mode. The rest of the process is similar to the work on a brick wall.

If you do not have a wall chaser, you can use an angle grinder. It is better to equip it with diamond discs, the diameter of which is 105-125 mm. To select the depth of the groove, consider the diameter of the cable to be laid, as well as the thickness of the putty layer. You need to cut the edge of the furrow step by step: first make a depression by 1 cm and pay attention to how the tool handles the load. If the concrete yields well enough, cut to the desired depth to the end.

What is this process for?

The design of a standard wall chaser has a lot in common with an angle grinder or angle grinder. A significant difference between the chaser and the angle grinder is the high speed of work, as well as the ability to conveniently adjust the depth of the cut groove. It can create a groove of such depth, which is required depending on the set technological tasks.

An angle grinder is an excellent analogue of a wall chaser, since it can be used to carry out repair work in residential and non-residential premises, where it is necessary to make special grooves or channels for laying pipes and electrical wires. In order to use the angle grinder as a wall chaser, a special cover is required. It will allow you not only to adjust the depth of the cutting tool, but also to carry out work without dust.

In most cases, when it is necessary to make a groove in the wall, craftsmen resort to using the following tools:

It is important to know! Only if the work of the master is directly related to the need to make channels in the walls every day, then it is better to purchase a professional wall chaser.

If you need to cut a channel in the wall during repair work, then an angle grinder is quite suitable for these purposes. And there is no need to purchase a special wall chaser attachment for an angle grinder, since you can make it yourself.

Chipping wooden walls

When conducting electrical wiring in a wooden house, incl. bath, chipping of walls is prohibited by fire safety rules. At its core, physically it would be simply cutting (gouging) a groove, which would be an impractical process. For such cases, there is external wiring, hidden by special cable channels, disguised as a tree.
