Repair of facades of houses. Features of repair of facades of houses

The facades of buildings are most often susceptible to the negative impact of the environment: there is a torrential rain, snow blowing a strong wind or stands the zero heat - all this to some extent leads to the wear of buildings. The repair of facades is preferably carried out in a timely manner to extend the life of the building and improve its appearance.

Content

Repair of the facade of the building includes several stages: plaster, painting and other works. But before proceeding with repair work, it is necessary to determine the nature of the destruction. For example, if a small crack is found in the wall, then experts are recommended to perform its diagnosis to determine the cause of the crack formation and prevent the emergence of new defects. Among the most common destruction of facades of buildings, specialists detect the following: cracks arising from the shrinkage of the building, as well as showering plasters, paints and the appearance of a salt laid.

Facade Repair Technology

Any repair work begins with training. First, it is necessary to clean the facade of the building from the old coating, if necessary - to repair the eaves, sings and the drainage system, catching up the existing tile. At this stage of preparatory work, you can decide on the nature of damage, and immediately schedule a plan of work. At the same time, it is necessary to resolve the issue with the insulation of the facade of the building and to water the waterproofing of all available seams.

According to the technology of repairing facades of buildings, after determining the nature of the damage it is worth solving how repair work will be performed - with the involvement of specialists or independently. If the building is a multi-storey, then it is better not to inflate and entrust work to builders who use the method of industrial mountaineering to repair the facade of the building. This will not only fully fulfill the plaster surface, but also to paint the entire surface of the building is much faster. Such a method allows to save money and time for the construction of forests or attracting an autotower.

Regardless of who will be engaged in the repair of the facade, you must first prepare the territory and establish a fence. This is especially true if the pavement takes place immediately before the facade, the passing part or the parking is located.

In order not to damage the flows and windows, it is necessary to protect similar places by the construction film.

Stages of repair work

The facade repair work is a long and labor-intensive process, so it is necessary to familiarize yourself with the sequence of repair work in advance.

Stages:

Preparatory work (inspection of damage to the facade of the building).
Cleaning facades from fragments and old plaster.
Stucco work. Applying layer of plaster will allow to align the surface and fill the existing small slots. If the cracks in the deep building, they are pre-filled with the mounting foam, and then cover the layer of plaster. The slots can be formed for many reasons, respectively, methods for their elimination can be different. Depending on this, experts choose the building material individually. If a small area is damaged, then it is enough to just shock the wall. In the case when a large area of \u200b\u200bthe facade is damaged, then there is a need to use a chain grid (the reinforcing layer to which plaster will be applied).
Surface treatment with primer mixtures. This is necessary in order for the paint well to keep on the surface. If you do not pre-process the facade of the primer building, then the paint will not hold for a long time, and over time, under the influence of atmospheric precipitation, it can break. In addition, paint consumption will be large.
The color of the facade of the building is the final stage of the repair work. The process of time consuming, and on the part it seems that it is easy to paint the facade of the building. But in fact, to beautifully paint the facade of the building, it is necessary to choose the appropriate tool and apply the paint in stages. It should be borne in mind that the first paint layer will be pale. In order for the surface to become homogeneous, without divorces, it is necessary to have a certain experience.

Overhaul of facades

Overhaul buildings, in contrast to cosmetic, requires certain skills and appropriate training.

The repair of the facade of the building is divided into two types:

Cosmetic.
Capital.

When performing overhaul, it is necessary to adhere to such a plan:

Performing the diagnostics of the facade of the building to determine the amount of work.
Preparation - stripping of the surface from paint, removing the layer of plaster.
Heat insulation and waterproofing of seams between panels, surface treatment with primer mixture, plastering.
Finishing works - facing the facade of the building with decorative materials (ceramic tiles, marble, decorative stone, siding), plastering, painting of the building.
The surface treatment of the water-repellent mixture (hydrophobization).
Repair of drains, gutters, air ducts, sings and ventilation.

Features of repair work The facade of the building includes certain rules. So, to remove the old paint from the surface, it is necessary to apply a special composition on the surface, which will soften it and allow it faster and better remove the paint even manually. If necessary, the surface can be washed with a stream of water under pressure, so the surface is cleared of small residues of paint, dirt and dust. Such technology will make it possible to remove several layers of old paint at the same time.

With the major overhaul of the facade of the building often arises the need to remove the remains of the cement mortar in the masonry. Well removes the old cement aqueous solution prepared on the basis of a special cleansing powder. Then the surface is thoroughly washed with water.

Often, the overhaul of the facades of buildings cannot be performed without preliminary surface treatment with anti-grain compositions. In some cases, you may need mechanical cleaning.

Repair of plaster facades

Damaged plaster, which began to crumble, can be restored independently. Consider more, how to independently plastering the facade of the building.

For work it is necessary to prepare such tools and materials:

shtailech mixture;
means for primer surface;
hammer;
capacity for mixing the solution;
plastic container or tank with a pulverizer;
wire mesh (rubber grid);
master OK;
rigid brush;
putty knife;
bucket with water.

If in the cold time, the first signs of the destruction of the plaster of the facade of the building were discovered, which were not immediately eliminated, then for several cold months, damage will only increase.

In the photo you can see the facade defect, which arose due to moisture and the effects of frost. Stucco on the facade of the building broke.

As soon as the stable temperature is established (during the frost it is undesirable to work with a solution), it is necessary to eliminate damage to urgently so that the brickwork laying is not collapsed.

How to repair the plaster facade of the building:

With the help of construction tools, it is necessary to clean the surface of the facade and seams.
Plots with damaged plaster should be considered, and the place is filled with a binding layer - a solution of plaster.
In order for all work to be implemented in a short time, you can use ready-made solutions. It will be good to keep the plaster solution prepared by yourself. Universal cement mortar (it is also used for brickwork) is prepared from water, sand and cement. Sand must be taken clean and not too small (grades size up to 2 millimeters), better than river. Before mixing with cement, it is desirable to sift it through a sieve to separate the small pebbles, pieces of earth and other trash. The finished solution saves plasticity from 1.5 to 5 hours. Time will depend on the quality of cement and proportions of the solution. The strength of the solution depends on the amount of sand - than it is less, the solution will be stronger and vice versa. For the preparation of the solution, the cement M25, M50 and M75 is used.
After applying a cement solution, dust and cement residues need to be removed with a rigid brush, and the surface is well mixed with water. It is necessary to moisturize the surface of the building for better clutch plaster with the base.
Now it remains to apply the solution for the second time. By consistency, it will be more liquid than the first. You can align the surface with special construction tools - rules or trussels, when the solution starts to be captured.
There should be at least 24 hours between each applied layer of the cement mortar.
After completion of cement masonry, you can paint the surface or apply a layer of decorative plaster.
