Do-it-yourself house facade repair plaster

In detail: do-it-yourself house facade repair plaster from a real master for the site my.housecope.com.

Many people use plaster to decorate the facade of the house.

Finishing work is one of the important stages in construction.

Thanks to plaster, not only a certain design and style of the house is created, but also the protection of the entire structure from impact and adverse phenomena is ensured. Plastering the house may sooner or later require renovation.

Such a process is carried out with their own hands, knowing all the nuances and features of the work.

Plaster has two functional purposes:

first of all, this coating provides the protective functions of the house from atmospheric phenomena, for example, rain and UV rays and from mechanical damage;
the second functional purpose is to create the desired design solution.

Facade plaster has several varieties, in contrast to which the composition of the mixture is laid.

Of all the types of plaster, the following can be listed:

All varieties are suitable for finishing the facade of the house. The main properties that the material should have are:

high level of vapor permeability;
water resistance;
resistance to temperature fluctuations;
elasticity.

Among the advantages of such material are:

high quality, which is characterized by elasticity and good adhesion to any surfaces;
the ability to store the composition for a long period without losing the desired properties;
the plaster is highly resistant to mechanical damage and weathering;
neither moisture, nor low or high temperatures, or mechanical stress are terrible for her;
no harmful substances are emitted from the material;
the house covered with plaster does not need any special maintenance. Some varieties of such material are cleaned with a regular sink, some do not need this at all, since they are capable of self-cleaning. The material repels dirt;
the plaster is characterized by a high level of vapor permeability. Thanks to this, a comfortable indoor climate is achieved;
there are ready-made compositions on sale. This makes the construction process easier. The very technology of coating the facade plaster is simple. There is no need to spend a lot of time and effort to carry out repairs;
there is a wide selection of materials on the market in various colors, shades and textures. It is very convenient, there is an opportunity to purchase the necessary plaster to create a harmonious design.

Finishing the facade with a plaster mixture

As for the disadvantages of plaster, we can only talk about an incorrectly selected variety of such material.... We recommend using a silicone, silicate or acrylic variety.

The lime or mineral type, despite its simplicity and availability, does not always meet the requirements for relatively high protection properties. In any case, a certain type of plastering material is suitable for each house, which will ultimately provide a high-quality coating.

The renovation process always begins with a preliminary examination of the condition of the plaster on the facade.... This stage is very important for the reason that it determines the further scope of work. The repair may consist in the elimination of defects directly, in those places where it is necessary, or a complete replacement of the entire material of the finishing coating will be required:

If, upon examination, small cracks are found on the facade, bulges that cover small areas of the surface, then you can make repairs directly to these places.
If cracking, shedding of the plaster, or swelling cover large enough areas, then the best option to eliminate them would be a complete replacement of the entire coating... This is also necessary for the reason that such defects arise due to improperly performed technology during the first finishing. Accordingly, if you carry out repairs and replace only the damaged areas, then soon you will need to repair the remaining part of the coating. In order not to waste energy and time in vain, it is better to immediately replace the entire finish.

After the inspection of the facade has been carried out, it becomes clear

in which places repair is required. This can be seen by the presence of cracks, chips or bumps on the surface of the walls.

It is also recommended to tap the entire surface and find places where a dull sound is heard.

In such places, it is initially required to remove the top layer of the material. To do this, use an ax or a hammer, with the help of which they chop off the material in the desired area with light taps.

Surface preparation consists in rubbing the damaged area after the old material has been chipped... It needs to be dry and even. Further work is carried out depending on the type of damage.

The wall is wetted with water, after which it is expected to dry completely... After surface preparation, they begin to replace the coating according to the usual technology of applying the composition, carry out its reinforcement and painting.

The process of repairing facade decorative plaster depends on the defects that have arisen... If we consider minor repairs, which consists in the elimination of cracks, fungus or mold on the plaster, then it is carried out as follows:

Cracks... If cracking appears on the surface, then first of all they needs to be expanded slightly by scraping... After that, sprinkle with water so that the surface becomes wet and then the area is rubbed using a solution. With the help of felt, the entire surface is smoothed and compared.
The appearance of stains spoils the aesthetic appearance of the house.... They can be caused by exposure to fire or smoke. You can get rid of them using surface treatment. using a lime mixture with milk or soap... With this solution, the desired area is treated several times. Typically two to three coats are required, with each coat must be completely dry before the next can be applied.
Mold... Mold is easy eliminated with specialized drugs... Such drugs are diluted in accordance with the instructions in the instructions and with their help the surface on which the mold has appeared is processed. It should be borne in mind that if mold fungi appear on the facade of the building, then it is best to immediately process the entire surface of the facade - this will prevent mold from developing in the future.

If repairs were needed due to peeling of the plaster from the surface of the walls, then this requires a slightly different repair technology:

Cleaning the problem area

Sealing the damaged area

During the repair process, it is important not so much to restore the damaged areas, but to eliminate the reason why the coating deteriorated. This will prevent repeated damage. It is always necessary to find the source of the appearance of stains, mold, and also understand why the plaster began to crack or move away from the wall surface. Having eliminated the cause, further repairs will no longer be required.

Despite the fact that carrying out repairs is a fairly simple process that you can do yourself, you should not overestimate your strengths.An improperly repaired surface can cause additional defects and will require repair in two to three months. It is also recommended to replace the entire layer of the plastered facade if technology violations were found during its application. It will also save money, effort and time.

Plastering the facade with your own hands is not difficult, but before going to the store you need to understand the nuances. You will need not only the plaster itself, but also a primer, spatulas and floats. Violation of technology leads to the formation of cracks, therefore, to repair or re-work. Here is everything you need to know to make the facade of your house pleasing to the eye for several decades.

Before dwelling on the choice of any plaster, you first need to decide for what purposes you need it (for insulation, alignment or decoration).

Inexpensive and versatile, but its service life is 10 years, while other plasters have 25. Consists of cement and filler. Such a solution can be made by hand. The gypsum mixture should not be applied to concrete, this will lead to cracking. First, the wall is covered with lime.

The wide range of colors and the long service life of this plaster attracts. But dirt sticks to it more strongly than to others, so the facade will need to be washed periodically, and you will have to work very quickly due to the speed of drying.All pollution from the surface is washed off by rain, it lasts a quarter of a century. Due to its high vapor permeability, it is recommended to use it if the base is porous (foam, cellular concrete).An example of silicate plaster, any colorSuitable for all types of base, lasts a long time, does not get dirty, but is expensive.

Insulation of the facade

When planning the main activities, one should not lose sight of the fact that when renovating the facade, the building's protection from external climatic factors should be taken into account, namely:

heat and sound insulation protection;
protection from precipitation and wind;
fire resistance.

In addition, the outer cladding of the building must be unpretentious in maintenance, and it is also desirable that it be self-cleaning. The domestic industry produces various types of finishing materials that meet the above requirements, but only a few of them will be considered in this article.

Facade finishing materials

Let's make a reservation right away that a major overhaul of the facade of a house can be accompanied by a complete renovation of its appearance through the use of new (most modern) types of finishing materials.

Among the well-known types of claddings, the following are especially popular:

finishing plaster mixes, distinguished by a very reasonable price and simplicity of the finishing (application) process;
siding decorative panels, which give the facade of the building a rather austere and attractive look;
traditional tile materials;
porcelain stoneware.

Let's consider each of these materials in more detail.

The use of plaster mixes (most often - as a preparatory layer) will allow you to hide all existing flaws and irregularities in the facade surface and get a completely attractive and uniform coating. Such mixtures are produced in two different versions, differing in their base, which can be ordinary cement or more expensive gypsum.

This finishing material allows you to obtain a homogeneous surface, the quality of which does not depend on the type of existing base (wood, brick or concrete).

The disadvantage of this choice is the increased labor intensity of finishing work and, as a result, an increase in the time for repairing the building (this is due to the fact that all plastering work is carried out, as a rule, by hand).

Siding facade

Siding can be used for finishing all types of substrates (wood, brick, stone or plaster); it is distinguished by its ease of installation and the following remarkable characteristics:

durability;
external attractiveness;
resistance to external destructive influences;
environmental friendliness.

When finishing brick or wood surfaces, siding panels can be mounted directly to the walls of the building. In the case of facing uneven surfaces, as well as for additional insulation of the facade of the building, you will have to use a crate made of well-dried bars with a cross section of 50 × 50 mm.

Siding installation

According to the manufacturer's instructions, the installation of siding panels starts from the bottom up.

The individual panels of the kit should not adhere very tightly to other elements of the kit, that is, they should be mounted with a small thermal gap. The working plate fasteners, equipped with large-sized caps, should be located strictly in the center of a specially prepared recess.

Clinker cladding

Before renovating the facade of a building, you should remember about such common types of finishes as tiles and porcelain stoneware, which are traditionally used as facade finishing materials. A wide range of colors and sizes of elements of such coatings allows you to choose the most suitable finish option for your conditions. Taking into account all of the above, their choice for finishing the facades of the building can be considered quite justified.

We also note that neither the tile nor the porcelain stoneware needs additional maintenance, while being distinguished by a good price-quality ratio. Thus, the choice of this classic finishing material, in principle, can be afforded to any owner of a private home.

Facade plastering is an action designed to insulate and decorate a house. This is a surface finish, and the continued use of such an old version indicates its effectiveness. The development of technology has given new recipes for compositions for plastering facades, some of them have become very popular, others are rarely used. Each of the options has its own advantages and disadvantages, we will consider them in more detail.Plastering methods are known to be different, but in order for the final result of any of the options to fully satisfy, the following qualities should be achieved:

the material must have a high permeability, the scientific name of this quality is vapor permeability, it will depend on this whether condensation will appear, whether the building will be protected from moisture penetration inside;

the material must have a certain resistance to moisture, that is, it must have the ability not to absorb moisture in dimensions leading to destruction;

ease of application - this requirement is very important for each material of external plastering, most of the buyers put this at the forefront;

the cost of the material is a determining factor in price and quality, which makes it possible to use the composition in places with difficult weather conditions;

the color of the material is determined by personal preferences and the general impression, the harmony of the general appearance.

It is very important to make the right choice and take into account the peculiarities of the weather and terrain. The durability and quality of the plastered facade will depend on how the selection of the material is carried out correctly.

Be sure to consider the following factors:

seasonal temperature fluctuations;
air humidity and the proximity of water bodies;
close location of highways;
predominance of low or high temperatures.

Regardless of the choice, the plaster must withstand all of these factors.

Plastering solution differs in the main component - the binder component. Today, such types of plaster for building facades are known:

mineral;
acrylic;
silicate;
silicone;
with stone chips.

It is necessary to make a decision only after analyzing all the features and taking into account the pros and cons of each option.

You can make a solution for plastering the facade with your own hands or from dry material packaged in bags, which is produced at the enterprise. Making a mixture with your own hands will significantly save money, but the slightest error can lead to disastrous results. Therefore, buying a ready-made mixture is an option that will not let you down, moreover, it is less energy and time consuming.

Options for plastering the facades of mineral-based houses have a number of advantages:

low material cost;
good adhesion of the mixture to the base surface;
high strength indicators;
good vapor permeability;
low degree of moisture absorption;
high resistance to low temperatures;
resistance to temperature extremes.

Of all the existing options, mineral finishing mixtures are the most budgetary. But this option for plastering also has a number of weaknesses:

it is impossible to paint over the mixture in the state of a solution, but only after application with the use of facade paint;
insignificant choice of color for dyeing;
low elasticity - cracks form at the slightest shrinkage.

Silicate formulations for external use are used very often. The mixture is applied in a thin layer, as it implies the parallel use of mineral wool insulation.

The advantages of silicate plaster are:

high degree of vapor permeability;
dust repellency of the mixture;
moisture resistance;
does not fade;
resistance to mechanical stress;
ease of maintenance.

But this option has disadvantages:

expensive material;
without work experience, it is difficult to apply the solution yourself;
difficult to remove if necessary.

Among all the existing options for plastering the facade, silicone plaster is considered the most high-quality and durable. Despite the high cost, silicone mixtures are used, as they provide a finish for a long period of time without restoration and repair.

The advantages of this finish are:

dust-repellent ability;
moisture resistance;
plastic;
does not fade in the sun;
retains its properties over a long period of time;
high resistance to mechanical stress;
applicable to any surface, has a high degree of bonding.

The disadvantages of this option are:

high cost of material;
the complexity of the application;
low vapor permeability.

This option has worked well in areas with high temperature fluctuations.

Acrylic mixtures have good technical characteristics: they are elastic and durable. It is necessary to carry out preliminary preparation in the form of leveling the surface. Rough leveling requires the application of cement mortar, especially for new buildings, which will certainly shrink. Acrylic plaster will not crack in this case, as happens with the use of a mineral composition. But the option using an acrylic mixture also has disadvantages:

expensive material;
has a low quality of fire safety;
low vapor permeability, additional ventilation is required;
absorbs dust that is difficult to remove.

To insulate the facade under plaster, mineral wool, foam or other similar materials are used. For such heaters, it is recommended to use an alkali-resistant fiberglass mesh.

The work on insulation goes like this:

the insulation is attached to the wall surface with glue or special dowels;
a layer of glue is applied to the insulation and the mesh is embedded in it;
insulation and mesh are covered with a solution;
decorative plaster is applied on top.

Before plastering the facade with your own hands, you need to prepare the surface on which the solution will be applied. The preparation features are directly dependent on the material of the walls. Consider what are the nuances of preparing a brick, concrete, wooden wall.

The brick surface is prepared as follows:

clean the surface from dirt and foreign materials;
remove the solution from the inter-brick joints;
remove any irregularities, smooth out bumps;
cracks must be repaired;
the wall is primed.

After the material has dried, you can start finishing the facade with the chosen decorative option.

If the wall on which the decorative solution will be applied is concrete, the following types of work are performed:

surface cleaning;
align walls, close up cracks, comb off bulges;
make a primer, make notches or use a mesh-netting.

Wooden surfaces must be prepared for plastering. This must be done like this:

clean the wall surface;
apply special solutions that protect wood from various negative effects;
stuffing shingles.

To plaster the facade with any of the options, it is necessary to perform a number of sequential actions:

prepare the surface of the building, clean up dirt, open the seams;
prime the walls or treat with special disinfectants;
reinforcement with a special mesh;
installation of beacons;
applying a mixture for plaster;
grout.

Some experts advise using reinforced mesh only in cases where the layer thickness exceeds three centimeters, but it is better to use mesh at any thickness. It improves adhesion and prevents cracking. For each version of facade plaster, one or another type of mesh is used:

galvanized steel mesh;
alkali-resistant mesh.

Facade plaster mortar can be applied in several ways. In fact, there are not very many textures, since the material is in contact with unfavorable environmental conditions. But even among a small number of textures. You can choose something to your liking. There are three main ways to apply the mortar:

This method creates an imitation of wood with traces of bark beetle burrows. The decorative solution is applied using two spatulas. Work starts from the bottom corner and gradually the solution is applied higher and higher. The composition is given up to half an hour to set, the time is determined approximately, depending on the ambient temperature. The external drawing is created with a trowel; vertical, horizontal or chaotic lines are randomly selected. The plaster should stand for about an hour and then be trowelled.

The solution with this method of application can be applied in several ways:

with a roller;
using a mechanical tool;
pneumatic tool.

For the application of the roller, the material is selected - a dry mixture.

This option is made on an acrylic component. The solution contains a certain percentage of marble chips. Apply the solution from the bottom up. Coatings in this way are highly resistant to mechanical stress and high humidity. This method is most often used when finishing a basement.

Before you start plastering, you must carefully read the recommendations of the manufacturers and the peculiarities of using the solution.

Wet asphalt plaster is considered one of the most effective for insulating the facade of a building. You can prepare the mixture yourself or buy a ready-made one, here everyone proceeds from their own capabilities and preferences.

Any construction technique has its own advantages and weaknesses. Also, wet plaster has lists of advantages and disadvantages. Let's consider both those and others in more detail.

Advantages of wet facade plaster:

does not take up additional space, does not make the residential building visually "thicker";
has a durability of service, on average up to thirty years, the facade looks great, does not need repair and renovation;
does not increase the load on the building;
has a soundproofing ability;
reduces the thermal conductivity of the building;
wide range of color palette.

But this option also has certain disadvantages:

in the process of plastering and until the material is completely dry, it is necessary to protect the surface from dust, which can significantly worsen the appearance of the home;
work can only be carried out in the warm season;
if the material has not yet "grabbed" the appearance of the facade may suffer from precipitation, it will take several days to harden;
it is also extremely undesirable to carry out plastering at high air temperatures, the solution will dry out and crack.

The plastering process is quite simple: a layer of wet plaster is applied to the insulation.

There are many options for plastering the surface of the house.Everyone chooses the best option based on local conditions, weather conditions, budget and personal preferences. Both an experienced craftsman and not quite an experienced craftsman can do the main work.

If you still have questions on how to plaster the facade with your own hands, watch the video. There you will find the most important structured information regarding the features of plastering facades with your own hands.

It happens that after a winter with record frosts and frequent thaws on some buildings, especially those covered with plaster, there is a partial damage to the coating of the outer surfaces of the walls.Capital or current renovation of the facade of the building in such a situation is simply inevitable. But is it possible to do in such a situation without the costly and tedious procedure of removing the entire layer of plaster?In fact, this problem even applies to new buildings. Over the past decades, there has been an active construction of residential buildings in the private sector. The natural desire to reduce the cost of the total cost of construction pushes customers to attract little competent contractors to the construction. At the same time, the construction technology is not always observed, standards and individual technological processes are not observed.In addition, owners of old houses also face the problem of damage to large areas of plaster. Damaged facades can be restored without completely removing the old plaster, which significantly reduces costs and time of work.Repair of plaster on the facade with partial removal - technological process:

Inspection of the facade of the building, assessment of the damage surface;

Removal of plaster in places of damage;

Cleaning and drying of removed plaster sites;

Working surface treatment with a primer emulsion - primer;

Filling damaged areas with plaster mixture, leveling and grouting;

Installation of a new plaster layer: application, grouting;

Priming and painting of a plastered facade.

However, you need to understand that repairing wall plaster in separate places is a technology that is designed to have a positive effect only if a clear sequence of all stages of the work process is observed. An indispensable condition for choosing a facade repair technology with partial removal of the old coating, with the expectation of a long-term effect, is a clear adherence to the technological map.When starting to renovate the facade of a cottage or a country house, the first thing you should do is carefully inspect the facade and assess the damage... There is a high probability that the coating was destroyed, not only in those places where it is visually noticeable.The easiest way to spot hidden damage to plaster on a wall is to tap it with a rubber mallet. Where such damage is present, the sound will be muffled, indicating a cavity under the coating or partial delamination.
