Quite often in the apartments there is a need for wall niches, where household items and equipment are placed. Works on the device niches are simple, but labor-intensive and traumatic, so you should carefully prepare for repair.
Selection of space for niche
The recesses are not made in the bearing walls, this requires the Permission of BTI, and it will be guaranteed against the change of project documentation. To implement your plans, a thick brick wall requires a thickness of at least 400 mm - in the frame houses partitions in the apartments are too thin, they are not suitable for niches. Determine which walls are relying short sides of the slab overlap - this is the bearing walls. Walls under the long sides of the slabs load are not perceived, they can be arranged niche. In the kitchen and in the bathroom of deepening make for practical purposes - there are stored kitchen and bathing utensils. In the bedroom, the recess is usually done in the headboard, where you can set alarm clock or night light.
Preparatory work
The cut-out geometry will depend on the functional purpose. The horizontal niche is made for visual increase in the length of the wall of the apartment, vertical - to visually lift the ceiling. Functional niches are designed to install household appliances.
Marking of contours of the opening on the wall
Use thread and pencil to apply arcs. Complex markup is performed using templates that are manufactured in advance. The opening should be done by 3-5% more than it is intended to remain for decorative decoration. Prepare personal protective equipment - glasses and respirator, there will be a lot of dust when working.
Tools
Prepare for work:
- perforator with a capacity of more than 1.5 kW, with a force of shock from 5J;
- Bulgarian with a diamond disk for working with a stone, a diameter of 230 mm;
- chisel, hammer;
- if the wall is concrete, buy a special disk for cutting metal reinforcement;
- the industrial vacuum cleaner for the collection of dust, formed when cutting the wall, household with abundant dust will not cope;
- drill with a drill on concrete.
So that the dust does not fall inside the electric tools, close the ventilation gap filters from gauze.
Application device
Drill perform holes in the wall of marking lines. Holes must be made by 2-3 cm deeply intended opening, as often as possible, the same length. Wall between holes. Strip the grinder. Remember that the cutting disc with a diameter of 230 mm is deepened into the wall by 50 mm. Separate parts of the walls are hollowed by a perforator and a chisel with a hammer. After forming a deepening, check the level of the back wall vertical.
If a niche of large sizes or it is made in an unstable wall, it is recommended to enhance it with metal corners or reinforced the contour. If a large load is acting on the wall with niche, invite a specialist for professional recommendations for strengthening the design. After receiving the deepening, align the surface with a plaster putty, clean the wall with sandpaper and proceed to the finish of the niche - decorating, fasten the shelves, laying down.
Despite the categorical prohibitions of construction norms, niches are often made in carrier walls. It is believed that a niche of a depth of Pollockich (15 cm) does not reduce the strength of the wall, in this case, all responsibility for weakening the design lies on the owner of the apartment.
