During construction or renovation, as a rule, it becomes necessary to lay new pipes and electrical wiring. For this, grooves are made in the walls and on the floor - special channels into which heating pipes, sewer and water pipes, as well as electrical wires are laid. In an intact form, the strobes do not look aesthetically pleasing, and the risk of their damage increases significantly, so the strobes must be closed up. How to close up the grooves in the wall and how to choose the mixture to putty the grooves correctly.
Sealing the strobe for wiring
The first step is to decide on the tools that you will need for the work ahead. So, how to close up a strobe for electrical wiring, you need:
- Spatulas (usually 15 and 120 cm are taken);
- Construction gypsum;
- Plaster solution (for example, Rotband).
Before the direct sealing of the strobes, you need to treat them with a primer. Why do this? The primer is used in order to further avoid cracks in the plaster and its shedding, because there is always a lot of dust in the grooves, which prevents the plaster from sticking to the walls of the fixtures.
The primer should be applied generously with a large but narrow brush, and in order to get into hard-to-reach places, you should douse them with primer, making strokes with the brush. But this must be done carefully so as not to slap everything around.
Next, you need to fix the wiring with ordinary plaster. The work is done quickly because you can work with plaster for only a few minutes, and it should not be kneaded in one in large proportions. It is necessary to fasten the wiring at intervals of 1 meter, so it will hold tight enough.
Now you will learn how to close the grooves. For this, a gypsum solution is taken and applied with spatulas in a groove. It is important to follow certain rules.
Firstly, the mortar itself must be thicker than with ordinary plaster. Secondly, the solution must be applied crosswise, to the walls of the groove, and not just vertically. This will help it stick to the surface better and will not create unnecessary bumps. Thirdly, you need to remove the excess solution by holding the trowel at a right angle from the outside, where the handle is located, and not flat. Thus, the gypsum mortar will adhere to the walls of the groove much better, and it will look neater, because the mortar does not reach behind the spatula. You need to remove the excess solution 1-2 times, this is quite enough. More details about the solution can be found by clicking on the link.
It must be remembered that when working with plaster or alabaster, the solution is suitable for only 5 minutes. Rotband solution will allow you to work for 20 minutes. Do not use the ready-made solution when it starts to set, it has already lost its properties.
Sealing a groove for pipes
Putting the grooves in the wall under the pipes is done in the same way, however, instead of building gypsum, mounting foam can be used to fix the pipes, and the pipes themselves are insulated using a shell made of polyurethane foam or foam. Thermal insulation of the pipes will prevent germs from growing, and the foam will securely fix the pipes in the groove. In general, the whole process looks like this: the strobes are cleaned of dust and primed, insulated pipes are installed, then they are fixed with foam, and after that they are covered with plaster mortar.
Summing up, it is worth highlighting several important points that must be observed:
- Primer. It is obligatory when sealing the groove both for pipes and for electrical wiring;
- Mandatory fixing of pipes and wiring;
- Application of herringbone plaster to the wall sample. This will provide better adhesion of the mortar to the surface of the groove;
- Removing excess mortar with a spatula at a right angle.
Gypsum mortar dries, as a rule, in 24 hours. After this time, you can start painting the wall or ceiling.

Do-it-yourself electrical wiring in an apartment It is believed that, on average, a modern apartment consumes about 8 kilowatts of power. So a 40 amp circuit breaker should be used. This is enough to protect against overload and short-circuit current. Residual current devices (the so-called RCD) are needed to protect people from electrical injuries, as well as during power surges. Most often, 2 RCDs are installed, one with a leakage current of 10 milliamps (for a bathroom) and the second
