How to perform waterproofing balcony. Waterproofing of the balcony using technology: coating, inlet. Preparatory work on waterproofing balcony

Today, the balcony or loggia is not used as a storage room where various unnecessary things are stored. Each family is trying to convert her balcony, loggia into a small cozy addition to the living area. Setting roof and glazing for this not enough. If you do not conduct waterproofing the balcony from the inside, its sealing and vapor barrier, it is possible to continue considerable financial losses. What are these works and how to execute them correctly you will learn from this article.

Waterproofing balcony

Waterproofing - protection of building materials and structures from the destructive effects of water. The results of the absence of waterproofing coatings can be seen on the balconies of the upper floors, which do not have roofs and glazing, which is constantly flowing from the roof. On closed balconies, moisture loggians falls inside due to poorly performed sealing work.

The destruction of concrete is observed in places of the adjoining of the balcony plate to the facade, its edges are greatly scattered and cracks and sinks are often visible on the plane.

What needs to be taken to avoid a similar situation? One of the mandatory conditions is to make waterproofing the balcony (loggia) with seams.

You can use the services of specialists, but it is justified for external work on the upper floors. From the inside, perform the waterproofing of the balcony with your own hands is quite real. It is necessary to pay attention to the sealing of all seams, regardless of their condition.

First, we consider what is the waterproofing of the balcony, the loggia.

On the scheme presented below, it can be seen that when conducting these works, the waterproofing mastic creates a protective layer, and seaming sealing and restoration of damaged parts of the balcony plate is performed using sealants.

Conditional scheme of waterproofing balcony

The materials used in the conduct of waterproofing are divided into several types:

The coating compositions are bituminous polymer, cement-polymer, bituminous rubber. They form an elastic coating that requires a tie from above.
Penetrating compositions are the most persistent and popular. Applied to the wet surface, fill all cracks. Also increase the strength of building materials by 15-20%. But it can only be used for waterproofing concrete surfaces.
Halter materials are polymer (viniplast, polyethylene) and non-polymeric (fiberglass, rubberoid). It is rarely used for waterproofing balconies (loggias), since work with them road and laborious.

Consider stages to make the waterproofing of the balcony and the loggia together with sealing.

Poland waterproofing

Works begin with the execution of a concrete screed. For an open balcony, you need to make a screed with a slope of 2%. It is necessary for free water supply from the surface of the slab. The screed is reinforced by a metal grid.

When performing a screed, three types of seams are required:

Compensation - formed when laying a clamping layer. Another name is temperature.
Forced - seams separating the screed on the squares.
Wailed - located in the place of the adjoining of the balcony plate to the facade.

In the future, in the seams, 50% are filled with sealing mastic, into which an elastic cord is pressed.

The screed is cleaned of dust and garbage, it is applied to it for better adhesion primer. One of the best - Primer WB.

On a moistened concrete we apply several layers of polyurethane mastic (for example, Hyperdessmo RV). The final thickness of isolation on the floor of the balcony, the loggia should be at least 20 mm.

In addition to the floor, the waterproofing layer must enter the walls to 150-200 mm.

Application of polyurethane waterproofing on the floor balcony (loggia)

Waterproofing of the loggia from the inside with the use of polystyrene foam and vapor barrier film

Sealing and waterproofing of the ceiling of the balcony from the inside

After glazing the balcony, the loggia sometimes we observe a unpleasant picture - the balcony flows. This could happen if it was not sealing and waterproofing the ceiling and a balcony roof (loggia).

With poorly spent sealing of balconies, the joints of the windows flow, the roof flows from above, floods the floors. How to eliminate this defect?

From the inside all work to eliminate leaks can be performed independently. We carry out the sealing of all seams. We use a polyurethane sealant Hermoplast or Emphic. Before smearing the defects, the grinder we separate the seams and cracks, we clean them from dust and wet the water. We also pay attention to the dark spots on the ceiling - in these places there may be microcracks, through which water also flows. They are also separated and sealing.

Sealing seams by polyurethane sealant

Next, survey the glazing of the balcony (loggia). Often the frames are installed with violations of technology. These flaws will have to be corrected with their own hands. Otherwise, having sealing and waterproofing the ceiling, we will constantly observe how water flows through the slots in glazing.

When installing glazing, a mounting foam is used. Under the influence of ultraviolet rays, the foam is destroyed, the water flows freely through these seams. It is necessary to partially remove the outer layer of foam, fill the formed groove with a hydraulic elastic cord. Under the influence of moisture, the cord increases in the amount and prevents water to flow in this place.

Leak at the bottom of the frames of the loggia due to bad sealing

Waterproofing the ceiling is starting from cleaning the entire surface and processing it with an antiseptic to protect against the appearance of fungal mold (for example, DALI). Then we carry out the sealing of cracks and chipping on the technology described above.

For the ceiling it is better to use polyurethane mastic elastomix or elastopas. They possess good adhesion and apply it to the moistened surface of the ceiling is not very difficult.

The ceiling is covered with mastic in two layers - the direction of the second perpendicular to the first. The waterproofing layer is rejected by a grid after the first layer. To create a solid crystal protective layer, you must give mastic to harden for 3 days.

When the roof is insulated to the ceiling, the sheets of foil polystyrene foam are glued - it also serves as vapor barrier. The seams between them also seal.

Roof waterproofing

You can not always make complete sealing and waterproofing of the loggia with your own hands. We are talking about the upper floors - the roof of the loggia flows and outdoor work is required. Who should repair the roof coverage, eliminate flow? It is impossible to engage in our own works - very dangerous. What to do in this case? It is necessary to invite specialists.

How work on waterproofing and sealing of balconies (loggias) can be viewed on the video on the Internet.

Conclusion

Now we know that waterproofing protects the balcony (loggia) from premature destruction under the influence of water, and sealing eliminates any leakage, not allowing moisture to get into unprotected surfaces.

As you can see, you can independently using modern materials, carry out work on sealing, waterproofing of the loggia and balcony. Protect them from even small leaks and references.

The balcony, the loggia will turn into a full-fledged residential area that can be used at any time for different purposes.

Often it is important to produce waterproofing the balcony, despite the fact that it is not glazed. Otherwise, an excess moisture can be absorbed into the floor, because of which the slab can be partially damaged over time (the risk of mold appearance) is also large. It is especially difficult to waterproofing the open balcony, because Its structures are constantly exposed to moisture. With internal waterproofing, you can cope with yourself, but for external it is recommended to invite professionals.

Available options

From the selected waterproofing option and the characteristics of the balcony depends on the process of conducting waterproofing work. Total two options for working and using materials will be allocated:

Picky.

The maximum easy way to make waterproofing the balcony yourself. Most often used to create a moisture-repellent layer from the inside of the loggia. In this case, bitumen masts that need to be diluted to waterproofing are used. Applied to the surface inside the covered balcony with a painting brush.

However, their level of protection is not enough for the external finish. Mastics are divided into two types - powder and coating. The first are sold in the form of a powder from quartz sand, cement, etc., are diluted with water or special solutions. The second type is applied according to the similarity of ordinary paint, it is necessary to heat a bit before use.

Rolled.

The process of application is characterized by increased complexity and requires special knowledge, so it is not recommended to make a rolled styling of the waterproofing layer with their own hands. Most effective with exterior decoration. Bituminous rolls of a certain size are laid on the surface and are migrated to it using a special device. Thanks to "gluing" with a concrete surface, the moisture protection layer serves the most long and efficient. However, on top of the bitumen sheet it is difficult to establish any elements of the external finish, therefore this method is most often used for floor-insulation of the floor on the open balcony and roofs.

Penetrating.

They are most racks to moisture, are mainly applied in crevices between the wall and the window frame, in the cracks, seams.

Preparation

In addition to purchasing all the necessary mastics, it is necessary to completely clean the balcony. If on the floor, walls, ceiling, any trimming was installed, then before starting work it will be necessary to completely dismantle, leaving bare concrete. Then you need to check the quality of the concrete slabs themselves. If they showed any defects (cracks, mold, irregularities, etc.), then they are required to completely get rid of them, hinged them with plaster or removing damaged areas (in the case of irregularities). After the completion of the work, dust and dirt are completely removed, and the concrete can be treated with special antiseptics.

In the event that the walls, the floor and the ceiling rotted to such an extent that the rusty parts of the reinforcement are visible, then they are completely cleanred from rust to the maximum, and then apply special protective compounds for metals. Too big cracks will have to expand and fill in with a screed. Small faults can be filled with conventional plaster. All major irregularities are also removed using a spatula and embedded.

If the concrete plate is damaged too much, then it will have to be replaced completely, but most often it can be found only in old and emergency houses.

Provided that all preparatory procedures were carried out, mastic and sheets will be more tight and smoothly falling to the surface, thereby making the coverage of more durable and high-quality. The high-quality waterproofing of the floor of the open balcony is particularly relevant if it is over the ears of the neighbors below. They don't want to buy them anyone.

Waterproofing process

Application of the moisture-repellent layer may differ depending on the surface to which it is applied. Also, the stages of preparatory work can also be slightly different.

Floor insulation

If the balcony is above a residential room, then its gender is required to hydroize, because Condensate accumulates on it, which can be collected on the floor due to the temperature difference and slowly destroy it.

The waterproofing of the floor on the open balcony can assume the installation of a special flooring for the floor with a slope of about 1-2% - it is required for free extension of extra moisture. It is desirable to reinforce the metal grid (especially if it is planned to install a heater, decorative tile, etc.). The screed must be divided into seams that are the following types:

Temperature - formed when laying the clamping layer.
Wasted. Located in the place of adjoining the balcony plate to the facade, most suitable for small loggias.

The waterproofing of the open balcony under the tile requires that the resulting seams are about half (can be slightly larger or less) were filled with moisture insulating mastic. Then the insulation is added to the remaining space (if necessary) or it is simply poured by concrete, then the tile is then put on top.

You can also go an easy way - either bitumen sheets are stacked on the purified and repaired concrete slab, or mastic is applied. In the first case, it is desirable to entrust the case by a specialist, because Perhaps the sheets will need to "catch" to the floor. In the second you need to go on the walls by 15-20 cm up.

Ceiling insulation

The ceiling on a balcony of an open type can also be waterproofing, curing it with mastic. If necessary, an additional film is superimposed so that the mastic does not flow from the ceiling.

But a normal mastic is applied to the ceiling, which time to absorb concrete. Application occurs in four stages:

The ceiling is cleaned and slightly moistened.
The first thin layer of mastic is applied.
After he dries it, it needs to be slightly moistened.
The second layer is applied. After that, the ceiling is desirable to moisturize 2-3 times a day for 2-3 days.

Conclusion

As you can see, you can independently using modern materials, carry out work on sealing, waterproofing of the loggia and balcony. Protect them from even small leaks and references.

Which can be used at any time for different purposes.

The balcony is a fenced plate, which is constantly under the action of atmospheric precipitation. In winter, the moisture fell into the pores of concrete expands, as a result of which microcracks appear. If you do not take action to protect, then the balcony stove is rapidly destroyed, but also will constantly spare from the dampness of the belongings on the balcony. Each owner of the balcony should be aware of the peculiarities and methods of waterproofing.

On the peculiarities of waterproofing

Scheme of waterproofing balcony

The water-repellent and waterproof additional layer on the floor, the ceiling and balcony partitions creates reliable protection of the destructive ingress of moisture.

Waterproofing is necessary regardless of the location of the balcony. For example, a balcony of the first floor moisture is not only from the environment, but also from the basement. But the balcony on the middle floor of the house threatens leaks from neighbors from the top floor.

Properly made waterproofing increases the service life of the balcony without overhaul, and also increases its comfort.

The technology of waterproofing the balcony depends on such factors:

type of balcony: open or glazed;

the location of relatively neighboring balconies: near or separately;

balcony design material.

On the open balcony of the last floor, the roof and ceiling waterproofing is performed. With a complex configuration of the balcony to the floor, liquid waterproofing is stacked.

Before waterproofing a wooden balcony, all design elements are processed by protective material, and natural ventilation is placed. Under the flooring of a wooden floor, a bias and drain on the street.

Main options for waterproofing

When choosing an option for waterproofing the balcony, not only the condition of its surface is taken into account, but also the material from which it is made.

Simultaneous use on one balcony of various options is allowed. The main waterproofing options are:

Works on waterproofing balconies are performed in three stages:

preparation;

selection of materials;

laying waterproofing.

Preparatory work

The quality of waterproofing and durability depends on the preparation. Preparatory work is performed in a specific sequence:

prepared base under the waterproofing layer. It should not have loose layers and protruding reinforcement. All irregularities are cut with a grinder;

iron brush the base is cleared of all contaminants;

concrete is removed around the protruding reinforcement. The reinforcement is cleaned of corrosion traces and is covered with a protective layer;

the ceiling is examined, and the volume of work on sealing is determined;

the balcony partitions are examined, and the volume of work on sealing is determined.

It has long been found that the waterproofing of the glazed balcony is reliable than the open. That is why double-glazed windows are installed on the basis of waterproofing on the balcony. Their tightness depends on the presence of outer cornice and from high-quality installation foam.

Choosing materials

The result of waterproofing equally depends on the compliance with the technology of work and on the correctly selected material. Conditionally materials are combined into several types:

When choosing, some features of waterproofing materials are taken into account.

Folgisolone and Tekhtonikol rolled rolling materials are supplied in two versions for creating various types of coatings:

self-adhesive coatings - a durable clutch with the surface occurs due to the lipomy bitumen layer. Aluminum foil gives material strength. Laying such materials is a time-consuming, but inexpensive process.

The coating materials in the form of various mastic is simpler for use. Their feature is that the screed is required on top.

Mastics with bitumen are sold in the finished form, so they are immediately ready for use.

Mastics with cement are purchased in dry form, and then, bred by water according to the instructions. The resulting mixture retains its qualities of no more than two hours, so it is prepared with small portions and immediately applied to the surface.

Step-by-step instruction for the floor

Depending on the materials used and the method of performing work, various technologies of balcony floor insulation are used. The most common technologies are most common.

Cast method.

Reliable, but expensive technology, which for a long time solves the problem with the water waterproofing on the balcony. The moisture-repellent layer is created by two options. If you comply with the requirements of the instruction, then work is easy to perform on our own.

"Hot" Option:

from the base of the floor, dust and garbage removes. To do this, we use the vacuum cleaner;

all cracks are embarrassed;

the concrete slab dry out well. We use a construction hairdryer;

liquid bitumen solution grounds the base of the floor;

around the perimeter of the balcony plate placed a formwork from plywood or dense cardboard high to 400 mm high;

metal grid is stacked for creating strength;

according to the instructions, the mastic is heated and poured;

with the help of scrapers, the mastic is evenly distributed over the entire balcony plate.

after drying, two more layers of mastic are stacked.

"Cold" option.

It differs from the "hot version" by the fact that the mastic is not heated. The sequence of work remains the same:

the surface is cleaned, and all cracks are removed;

the concrete plate is drying and covered with primer;

on the perimeter of the balcony, formwork is installed;

metal grid creates strength for the laid mixture;

the cold mixture is poured, and then, aligned with the rule or scraper.

Fooling method.

Simple technology made this method popular with balcony owners.

Its advantages include, firstly, special knowledge is required to apply, secondly, service life up to 6 years, thirdly - affordable price. At the same time there is a disadvantage: bitumen is rapidly destroyed at a negative temperature. It limits the use of materials on open balconies without special additives.

The coating materials are superimposed in a hot or cold form on the following technology:

from the surface removed dirt, dust, leaps;

degreased coating location;

2 layers of primer are applied;

the hydrochroopying composition is distributed on top of the soil.

Paintack method.

The technology associated with sticking several layers of sheet or rolled material, familiar to many. It is equally suitable for balconies made of concrete and wood. However, such technology recently is rarely used due to such flaws:

before laying requires painstaking surface preparation;

it is difficult to lay material with large dimensions on a small balcony platform;

after laying some time on the balcony, a specific smell of material is preserved;

between fragments of the glued material are formed seams that often give leaks;

temperature fluctuations are negatively reflected on waterproofing for such technology;

the waterproofing layer is necessarily protected by a concrete screed. If you make a screed, there is no possibility, then another waterproofing technology is selected.

Works on this technology are performed in the following order:

rights are removed from the balcony plate, and cracks close. Then, it is cleaned and dried;

the material is dispedicued by the size of the balcony;

a brush is applied mastic;

we bring the material on the walls of at least 20 cm;

rolled and stacked on mastic roll material;

if necessary, the second and subsequent layers are also stacked on mastic;

the edges of the rolls are put on moisture-proof material with additives from polymers.

Important! During the work on such a technology, the air temperature and the balcony should not be descended below +10 ºС.

Stuccoat.

The technology has gained widespread use due to simple laying. It is suitable for any surface. Inexpensive mixtures with cement or polymers are used as a material. Plastering isolation well interacts with various coatings, for example, with tiles.

Works are performed in such a sequence:

the surface of the plate is cleaned and put off;

the thin layer is applied primer and is left for drying;

a stucco solution is prepared;

the first layer is superimposed. Special attention to the joints and corners;

after 30 minutes, the next layer of solution is applied. Consistently stacked no more than four layers;

the laid waterproofing coating dries several days. At this time, it should be protected from mechanical impacts. In addition, so that the coating does not swing, in the first day every three hours it moistened from the sprayer. In the future, moisturizing is made up to three times a day.

At the final stage of the waterproofing of the floor on the balcony slab mounted frame frame. OSB plates are attached to it, and the linoleum or other finish coating is stacked on top.

Step-by-step instructions for the ceiling

Atmospheric precipitation requires to protect the ceiling. This is especially important when the balcony is located on the top floor, or the upper neighbors did not take care of the sealing of its balcony.

Usually the upper balcony stove is isolated penetrating composition. At the same time, this sequence is selected for the arrangement of waterproofing:

the entire surface of the ceiling is thoroughly swelling from whitewash and paint with a metal brush;

the prepared surface is wetted by water;

On the balconies of the last floor of the house, work on the sealing of the roof is additionally performed.

This sequence of work is selected:

on the roof, the backrueroid is stacked;

on top of the rubberoid applied a protective layer of mastic;

sometimes an additional protective design of roofing materials is mounted;

insulating joints of the joints;

mounted taps for assembled after rain of wastewater.

Usually after waterproofing the ceiling, the stall state of the balcony is checked. Frames installed in violation of technology, a frequent cause of moisture from hitting the balcony.

Step-by-step instructions for balcony partitions

Waterproofing is made according to the technology that does not differ from the treatment of the floor and the ceiling. Optimal is the isolation using foil polystyrene foam plates. The stove is glued to the partition with a building mixture with high moisture resistance. For interputric seams, a reinforcing grid is used.

The following sequence of work is selected:

the coating waterproofing layer is applied to the moistened surface of the plates;

not earlier than five hours, perpendicular to the first layer is applied another protective layer;

outdoor cladding of the layer is performed by painting or plaster.

So, if waterproofing work is performed neatly without disrupting technology, the safety of the balcony and the comfortable decor on the balcony is guaranteed. In addition, it is possible to perform waterproofing a balcony for any owner having small skills in construction.

How quickly and just make waterproofing floor balcony, look in our video:

In the last decade, the services of glazing the loggia got widespread. Every day, there are more and more wishing to give her a more attractive look. There is another reason. Sometimes there are a balcony from above that make thorough sealing is simply necessary.

At the same time, it is important to understand: that this room becomes a cozy continuation of the apartment, one glazing is clearly not enough. It is no less important to protect it from moisture penetrating the street. For this purpose, laying special materials is used. Quite often, experienced masters hire such work, but the advice of professionals will help to cope with their hands even a newcomer.

This concept includes a complex of work aimed at protecting the construction facility from humidity. Water can penetrate or loggia during the rain, snow, with evaporation from the basement (on the first floors), from the roof or the top floor.

The waterproofing of the balcony outside and from the inside allows you to create a durable protective layer of special materials that prevent moisture inward. Due to this, it is possible to solve several tasks at once.

Protection against destruction. Finding into microcracks of concrete or other building material, moisture begins to destroy it. As a result, it will be necessary to repair very soon.
Blocking the development of mold and fungus. High humidity in the room sooner or later leads to the appearance of fungus and mold on the walls, ceiling and floor. Such a phenomenon can often be seen in the bath or sanitary node, where the increased humidity is constantly present. This factor negatively affects the health of the residents of the apartment, contributes to the appearance of unpleasant odor. Waterproofing of the loggia from the inside will completely solve this question.
Corrosion protection. Metal attachments and elements in contact with water are subject to corrosion. The appearance of rust testifies to the beginning of the destruction of the metal.

In waterproofing, all surfaces of the loggia need: walls, gender and ceiling.

Types of materials

The construction market market today offers dozens of items of all kinds of materials. The construction wizard can easily choose a suitable product from this assortment, the newcomer will have to be needed in this matter. It is better not to rely on advice advice in the store, but to choose the desired building material in accordance with construction standards and requirements.

In this case, the waterproofing of the balcony from the inside will give a good result. All coatings are divided into just a few groups.

Caution (they are also often referred to as cast polymer coatings). This option is one of the most reliable and lungs in the installation with your own hands. Typical representatives of this class are asphalt coatings, mastic. The only drawback of such technology is a high cost.
Impregnation. These materials deeply penetrate the building material and reliably protect it. There are special penetrating compositions for concrete, wood, other materials.
Rolled. Installation of such protection against moisture will not allow the tenants to regret their choice. These polymer-bitumen coatings guarantee high reliability and long service life, but the laying requires large labor costs and experience.
Coloring formulations. The main purpose of such materials is to protect against moisture of metal elements. Among the advantages are relative low cost, simplicity of isolation.
Plastering. This method is considered one of the most famous and simple. At the same time, for many years of use, he proved its high efficiency.
Sheet protection. This class is represented by metal and plastic sheets. It is rationally used only in cases where other options cannot be applied for any reason.
Injection defense. This species is used for point insulation cracks, seams. Such sealing of the balcony becomes possible using binding solutions.

Preparatory work

Before proceeding with the repair work with your own hands, the surface must be carefully prepared. This will depend on the quality of the execution and service life of the coating.

In the presence of outdoor decorative finishes, it is dismantled. All work needs to be taken carefully to avoid damage to the concrete slab.
The slab itself inspects and find all potholes, damage and cracks.
All zones with loose contained concrete are removed using a perforator.
Carefully clean the base from dirt and dust. You can make it quickly and conveniently using a brush with long rigid versinks.
If small cracks are present on the stove, they are slightly expanded by a perforator. This will allow the solution to penetrate deeper and well strengthen. Large cracks are leveled to the P-shaped stab.
If fittings were exposed during the destruction of the balcony plate, it carefully remove signs of corrosion. The best chemical composition is coping with this.
The metal purified from rust is coated with an anti-corrosion composition.
Before waterproofing the balcony plate, it is restored. To do this, you can use the usual cement or special compositions.
Inspect the walls of the balcony and roof, mark all the problem areas in which the balcony flows.

Is it possible to do without glazing

Many are asked about whether the waterproofing of the open balcony needs? Specialists agree on what is needed. Despite the fact that atmospheric precipitation will continue here, the balcony stove remains sufficiently protected from the penetration of water. This noticeably prolongs its service life, slows down destruction.

Those who decided to completely block the entry of humidity, still have to think about installing double-glazed windows. This is especially important in cases where we are talking about the waterproofing of the balcony over the erker or other residential premises.

First of all, double-glazed windows and outdoor cornis are installed. All gaps and cracks eliminate. Usually the balcony after glazing seal the masters themselves. However, if after that the cracks remained, you can cope with them with your own hands. You just need to use a mounting foam or sealant intended for use in temperature differences.

Floor arrangement

First of all, you should make sure that the moisture is removed correctly. If the bias is made from the wall, the waterproofing of the floor on the balcony can continue. If the slope is made to the wall, then all the water will flock to the house. It needs to be corrected with your own hands using a screed. For this prepare a mixture of cement and sand (ratio of 1: 3), they apply it to the purified base of the balcony plate. The angle of slope for the injection of moisture should be 1-2 degrees to the outside.

After the screed dry and hardens, you can move to further actions:

Clear the base from dirt, dust, carefully moistened.
Cover the plate with a layer of penetrating material. It is best to make strokes always in one direction. This will help prevent disclosure.
After drying, the surface is covered with a second layer. This time, smears are made in perpendicular direction to the first layer. It will give maximum protection from water.
3 days this layer is periodically wetted, not allowing to dry.
The next layer is a rolled foil insulator. Sheets impose a mustache in several see. The locations of the links are glued together with mastic.
Floor bars are installed on the floor, and the gaps between them are filled with polystyrene foam.
All formed seams and joints eliminate the mounting foam.
On bars laid a draft floor. For this, OSB plates are often used, fixing them with self-tapping screws.
Conduct the floor finish.

If you need to protect the balcony from moisture above the erker, the porch or alkey, then the insulation should be carried out as carefully as possible, since the appearance of the leakage will damage the inner repair of the premises located below.

Work with walls and partitions

For the decoration of walls and partitions during the waterproofing of the balcony, it is convenient to use rolled materials, such as foil rolled polystyrene foam. It is fixed to the vertical surface with the help of a building mixture. When buying this mixture, you need to pay attention to its frost-resistant characteristics.

After the layer is frozen, the surface is abundantly wetted with water and covered with a coating composition of 2 layers. The waterproofing of the balcony in a wooden house is carried out with the help of special transparent varnishes that do not disturb the appearance of natural wood.

Proper ceiling finish

For ceiling work, you can call the wizard or cope with this task with your own hands.

If the balcony is flowing at the top, the question arises: "What to do?" Let's start with the fact that all the flows of the roof are found at the preparatory stage, through which moisture penetrates inside. Usually there are quite a lot of them and it is not difficult to find them - divorces are formed around the cracks, wet to the touch. During the repair, all flaws of the ceiling on the balcony are eliminated:

for better adhesion, the ceiling is abundantly wetted with water;
to the surface of the ceiling with the help of a brush, a layer of mastic is applied;
