How and with what waterproofing of a balcony is carried out. Waterproofing a balcony: simple ways to waterproof a wooden loggia above a living room

Application natural materials When building a home, it is always relevant, thanks to its environmental friendliness and decorative finish. Balcony waterproofing wooden house, carried out in the correct sequence and in compliance with the work technology, will ensure long-term operation designs.

Wood materials are able to hide surface defects and have good soundproofing properties, creating an optimal microclimate for the home. The exterior finishing of solid wood loggias requires high-quality protection from the effects of atmospheric phenomena and temperature changes. Waterproofing wooden balcony is a set of measures to prevent moisture from entering the structure.

The need for work is due to:

  • normal functioning of the building;
  • increasing the service life of the coating.

Heavy wetting of surfaces can lead to the development of mold and reduce the decorative value of the tree. Subsequently, the material may lose its strength and attractive appearance, and irreversible deformation of the coatings will occur. Properly performed waterproofing of a balcony in a wooden house will prevent swelling and the appearance of cracks, leading to the destruction of the structure.

The technology of work depends on the type and functional purpose loggias. It is important to take into account the features of open and closed structures, base and topcoat material.

The choice of waterproofing layer option should also include the intensity of use and the intended purpose of the balcony (recreation or work area, storage room).

Materials for work


Waterproofing a balcony in a wooden house is done using special materials, different in purpose and application methods. Floor products are represented by liquid, roll, membrane and film (polymer) finishing options. There are several main types of insulation for walls: painted, cast, pasted.

Wooden parts must be treated with fire retardants, special compounds with antiseptic and water-repellent properties. Fungus and mold have a destructive effect, so it is important to prevent their occurrence.

The wood will retain its attractive appearance and strength when applied with impregnation, paint, or varnish. Transparent compounds emphasized natural texture and surface pattern. It is recommended to apply the varnish on surfaces previously coated with drying oil. The final layer of finishing can be additionally sealed with penetrating compounds.

  • hammer drill and mounting hardware;
  • cement, sand, beams;
  • means for waterproofing and treating floors;
  • expanded polystyrene and OSB boards;
  • foil vapor insulator;
  • sealant, polyurethane foam;
  • reinforced mesh.

Timely waterproofing of the balcony floor in a wooden house during construction will eliminate the need to remove the covering in the future. The work plan includes the creation concrete screed, installation of roll insulating material coated with bitumen or penetrating mixture. Only after completing all stages can the board be laid.

Waterproofing options for an open balcony


Expert recommendations will help you figure out how to waterproof a balcony in a wooden house correctly. There should be a slight slope on the surface of the open loggia, which will help prevent the accumulation of water. Excess moisture is absorbed into wooden surfaces floor on the balcony and leads to deformation of the material. The permissible difference in the height of the platform level is no more than 4 cm, which will preserve the hydraulic properties of the insulation.

The waterproofing layer can be made using various technologies:

  1. Laying special metal sheet. Insulation is installed during the construction of the home. It is imperative to provide a gap between the coverings for ventilation.
  2. Liquid rubber will ensure the tightness of the wooden floor. The finishing surface is removed, all cracks are sealed with mastic, and a layer of mixture is laid. Upon completion of the work, the final installation of the external covering is carried out. It is important to consider the permissible weight for certain type designs.
  3. Application of insulating boards. Sealing is achieved by placing the material under finishing coat floor.
  4. Roll waterproofing, or applying bitumen mastic. The advantage of the options is the availability and low cost of materials.

High-quality waterproofing of a wooden floor on a balcony must maintain a certain sequence of work. Initially, the surface should be prepared. At this stage, if necessary, it is removed old layer isolation. After laying the waterproofing layer, the selected finishing material is installed. Finally, you will need to treat the wood with an antiseptic.

Having determined the option of how to waterproof a wooden balcony, it is important to maintain the correct algorithm:

  • laying a rough layer of rolled insulation;
  • insulation layer flooring;
  • use of coating compounds;
  • finishing floor covering.

If the final covering of the floor of the open loggia is tiles, before installing the insulation you will need to apply a primer and level the base. The result should be a durable seamless coating.

Closed balcony waterproofing technology

Waterproofing the floor of a balcony in a wooden house with closed type The design is practically no different from the options for open loggias. Additionally, attention should be paid to the ceiling and walls. Treatment ceiling surface mastic with a polyurethane composition will provide the necessary protection from moisture. On the outer plane it is recommended to create roof covering, or perform work similar to floor waterproofing technology.

The general scheme of waterproofing floors consists of a coating with a liquid insulating composition, a layer of insulation, a water barrier, a layer of rolled materials and sheathing. Finally, the external roofing material is installed. This option is suitable when using sheet-type coatings. In case of roof design soft tiles, you will need to perform lathing continuous type in combination with rolled waterproofing materials.

The following list will help you figure out how to waterproof a balcony in each individual case: available ways carrying out work on walls:

  1. Pasting method. Materials with a self-adhesive base or requiring exposure are used high temperatures. Roofing felt or its analogues can also be used. The application process is quite labor-intensive and requires special knowledge and skills during installation.
  2. Painting method. Provides for covering the surface with a protective varnish containing rubber components. The disadvantage of this method is the need for frequent and regular renewal of the insulation. The total cost of varnish products makes this option quite expensive.
  3. Powder method. Used as a waterproofing material cement mixtures in combination with hydrophobic additives (tile adhesive, liquid rubber, special plaster). The resulting coating is not resistant to mechanical damage.
  4. Water repellents. The method is based on the use ready-made compositions, which have the necessary insulating and water-repellent properties. A high degree of surface waterproofing is achieved. It is recommended to use water repellents for interior work, in external conditions the layer is subject to severe destruction under the influence ultraviolet rays.

Proper implementation of the technology for laying waterproofing for wooden balconies will ensure reliable protection structures from exposure to moisture. It is possible to carry out the work yourself, using proven advice from experts. Qualitative waterproofing layer will prevent deformation and increase the durability of the wood material.

IN modern apartment a balcony or loggia often serves as a room suitable for a comfortable stay for residents at any time of the year. To do this, a balcony frame with multi-chamber double-glazed windows is installed in the room, a roof is installed, which is then insulated along with the floor and walls.

To give an aesthetic appearance, the inner surface of the balcony is trimmed or sheathed with building materials, while many of them lose their quality and their appearance when exposed to water or in conditions of high humidity.

Therefore, when carrying out exterior finishing of loggias and balconies, increased attention should be paid to protection from moisture - waterproofing, the violation of which can lead to damage to finishing materials and, as a result, financial losses.

When answering the question of why and why moisture protection is needed on loggias and balconies, it is necessary to take into account that damaged waterproofing of loggias and balconies can lead to the following unpleasant consequences:

  • Loss of quality of finishing materials due to constant exposure to liquid - warping and twisting of wooden frames made for fastening PVC panels, cracking of plaster, peeling of tiles, swelling of the laminate, leaking of the hatch on the balcony.
  • The formation of fungus and mold, damaging the finish and worsening the appearance of the room.
  • Accelerated corrosion of steel finishing parts and internal load-bearing reinforcement of concrete slabs located in a closed, humid environment without access to air.

Main types of waterproofing materials for household use

Waterproofing of balconies or loggias is carried out using materials that differ from each other in their chemical and physical parameters, application methods and cost; depending on the application technology, they can be divided into several groups.

Backfill

This type of waterproofing is mainly used when carrying out construction work V basements to isolate the floor from soil moisture. On the balcony, it is better to place loose waterproofing in special formwork guides and, after application, cover it with a cement-sand screed for fixation. Betonite clay, perlite sand, crushed polystyrene foam, glass wool, industrial waste in the form of ash and slag (expanded clay) are used as insulating materials.

Painting (coating)

TO this species include varnishes and paints for wooden floors, epoxy, polymer and bitumen mastics for hot and cold application for sealing wood and coating concrete surfaces. Usually applied with a brush or roller, after hardening they form a sealed and elastic water-repellent film; an example of a material of this type is Technikol mastic.

Impregnating

Substances deep penetration are absorbed deep into the surface up to several tens of centimeters and form crystals there that repel moisture and allow air to pass through. Hydrophobic liquids resist capillary penetration and can be applied by spray, brush or roller methods, one example being well known in construction industry Penetron, as well as Monolit-20M, Granit-28, Aqua-Top and others.

Pasting

This type includes rolled materials - roofing felt, roofing felt, polymer-bitumen sheets and tapes (Titan, Nicoband). The material is laid out overlapping on the surface, the seams are sealed with glue or heated bitumen. Insulation is difficult to apply - it requires a burner to heat the joints and skills in working with rolled bitumen materials.

Cast

They are polymer resins that are poured onto concrete surface in a heated or normal state, these include ordinary resin and modern materials(Drizoro Maxelastic Pur). Polyurethane resins cover the surface without seams and are effective in waterproofing not only concrete, but also metal surfaces.

Dry mixes

The most popular class of waterproofing materials, widely used in construction industry and allows for good insulation. Dry mixtures are supplied in paper bags and before use are mixed with water using a construction mixer, just like ordinary solutions for plaster and screeds. Applied to the surface using a spatula, brush or roller, after hardening they form a durable water-repellent film. The most famous dry waterproofing mixtures are Ceresit, Knauf, NTs.

Waterproofing balcony floor

When choosing waterproofing for a balcony under tiles, if you apply it yourself, you should take into account many factors - the cost of the material, the complexity of applying the coating, the need for special tools, the degree of protection from moisture penetration from below the slab. If waterproofing is carried out open balcony, the range of operating temperatures of the material is taken into account. For household use Dry mixtures that meet the specified requirements are best suited, and unlike common bitumen resins, after drying, you can walk on the insulation without consequences.

The only problem during application is the need to thoroughly mix the dry mixture with water, which cannot be achieved without a construction mixer. The way out may be to use a household drill or hammer drill and an inexpensive commercial whisk for mixing. The process of waterproofing a balcony floor consists of the following work:


To perform the work efficiently, you should use only clean containers, otherwise individual fragments of frozen building materials will compromise the integrity of the insulation. All dry mixtures are mixed twice with a break of up to 10 minutes to activate the binding components. Usage time ready solution limited and usually does not exceed one hour until completely dry.

After preparing the mixture, part of it is poured onto the floor and spread over the surface with a flat spatula 200 - 300 mm wide, the procedure is repeated until the surface to be treated is completely covered. When applying, you must ensure that there are no gaps on the floor.

Typically, the waterproofing coating is applied in one layer; to improve its quality and density, you can use a thicker consistency of the solution within permissible deviations. The areas where the waterproofing tape meets the floor are especially carefully coated - all cracks must be closed.

Coating the floor with waterproofing mastic

Mastics are the most budget view insulating floor covering, the material is supplied in finished form, work is carried out at a temperature environment more than 15 C and humidity from 60%. For normal polymerization, these climatic conditions must be maintained for 12 hours after work.

After preparing and priming the surface, mastic is applied to it using a wide brush; if the solution thickens, you can use a spatula. The hardening time depends on the thickness of the applied layer and is usually at least 2 days from the moment of application.

Waterproofing walls

To protect walls from moisture, methods similar to concrete floor– after cleaning and priming the surfaces, they can be coated with mastics or hardening mixtures. A good way to seal a wall is to waterproof balcony slabs when insulating a loggia or balcony with a sticker of foiled polystyrene foam (Isolon), which is also a sound insulator. Before installing it concrete slab it is better to impregnate with a hydrophobic composition (Litsil, AVIS, Litos, Aquabarrier).

Moisture protection for balcony ceilings

Ceilings on balconies can be ready-made in the form of concrete floor slabs or installed during glazing by installation specialists balcony frames. To protect the moisture of a plastic or wooden balcony, depending on the type of roof, different methods are used.

  • When insulating a concrete ceiling slab, exterior coating methods outside the balcony are mainly used. For these purposes, it is more practical to use adhesive sheet or roll materials based on bitumen, which are laid on the surface ceiling slab overlap and are connected to each other by heating the seams gas burner or a powerful hair dryer. To increase the tightness of the coating, the joints are additionally filled with liquid bitumen.
  • If the balcony is insulated from moisture light roofing from profile sheets, metal tiles or plastic, when carrying out external work outside the balcony, methods similar to protection from moisture are used concrete ceiling. Waterproofing a balcony ceiling from the inside or from neighbors above includes coating it bitumen mastic or pasting with Vibroplast strips.

Rice. 10 Waterproofing the balcony roof from the outside during insulation

Do-it-yourself internal waterproofing of a balcony is quite simple - it does not require the use of special tools or professional construction skills. To protect floors from moisture on an insulated or open balcony, it is more practical and easier to use dry mixtures; the walls can be treated or covered with any water-repellent compounds and materials (mastics, impregnations, synthetic films). It is best to protect the balcony ceiling from moisture with mastics or rolls of bitumen-based self-adhesive materials; sealant can be used to seal cracks.

Sealing and waterproofing are mandatory measures that follow the repair of a balcony or loggia. When a balcony leaks and water pours inside it, moisture causes damage. internal surfaces and insulation, if available. This negates all efforts on insulation and finishing.

In this article we will discuss what actions can be taken to insulate balconies and loggias, and what materials can be used. In addition, you will learn about the necessary preparatory work.

Materials for waterproofing and sealing. Preparatory work

First, let's figure out what the difference is between waterproofing and sealing.

Waterproofing is the protection of the ceiling or balcony slab against leaks: sealing all cracks that may form at seams, joints and cracks. In addition, the concept of “waterproofing” also includes protection of the surfaces themselves from moisture using special coatings.

Sealing is the subsequent treatment of seams and joints with special sealing compounds that have undergone waterproofing procedures. All seams and gaps of the constructed glazing structure of a loggia or balcony are also treated. Next, we will tell you how to independently organize sealing and waterproofing of a balcony or loggia.

Materials for insulation and sealing

How to cover up or seal leaks? The most commonly used is the following:

  1. Elastic coatings - usually based on bitumen. Used as a waterproofing layer under rolls roofing materials.
  2. Polymer - made on the basis of polyurethane, have high elasticity. These are various mounting foams and sealing compounds.
  3. Rolled are materials for flat roof on a bitumen basis. Glassine, roofing felt and the like.

Preparatory work

Preparations for sealing are carried out simultaneously with preparations for balcony repairs. Speaking of the question “who should repair the balcony.” You can involve housing and communal services in repairing the balcony slab, but you will have to deal with its roof, walls and parapet yourself.

We inspect the surfaces: places where water flows are determined visually. The ceiling may show dried water stains, blistering paint, and/or traces of mold in areas of leakage. We will seal them. We are looking for the same thing on the bottom side load-bearing slab. Along the way, we examine it for destruction. Then we begin repair work.

Leak on the balcony: localization of places requiring waterproofing and sealing

During the repair process, we check the slope of the balcony slab. It should be 2-3 C° from the wall of the house. This will ensure water drainage and will not accumulate on the stove. If for some reason there is no slope, then we eliminate this drawback.

Mix a mixture of cement and sand in a ratio of 3/2, the screed should be thick enough and not spread. We spread the mixture onto the surface of the slab and distribute it using the rule so that the layer near the wall is thicker. Using a level, we check the resulting angle and adjust it to 2-3 C°. The thickness of the screed should not exceed 4-4.5 cm.

How to waterproof a balcony: organizing the slope of the slab

Note:when laying cement screed it is necessary to organize expansion joints where the slab meets the wall of the house. This will compensate for the expansion and contraction of the screed under the influence of temperature changes. The width of the seams should be 10-12 mm.

If the balcony is very long, then additional “forced” seams are made along the slope of the slab. On a narrow and long balcony they are located every three meters, on a wide one every 2m2. They can be made both when laying the screed layer, and cut after it hardens.

Do-it-yourself waterproofing of a loggia: expansion joint

Waterproofing and sealing

The work for open and closed balconies is different, so here we will describe them separately. A description of the roof insulation will also be given in a separate paragraph.

Insulation and sealing of an open balcony

After the screed has completely hardened (14 days), we will organize waterproofing of all seams injection materials based on polyurethane. Alternatively, the seam can be sealed by inserting an elastic band into it. It is pressed into the seam, and everything is sealed with waterproofing compound on top. This is what it looks like:

Waterproofing a loggia with your own hands: laying an elastic cord in expansion joints

After the waterproofing has hardened, we begin sealing. The sealant is used in the same way as waterproofing, based on polyurethane, applied with a spatula. Next, the entire surface of the slab is coated with a composition that reduces water absorption by concrete.

Balcony sealing: fully sealed seam

We isolate a closed balcony or loggia

Sealing the seams of the load-bearing slab is done in exactly the same way as described above. We pass the seams of the walls and ceiling of the loggia that have cracks from the inside polyurethane foam. After it has completely hardened, remove excess material using a knife or metal spatula, and treat the seams with a sealing compound.

Waterproofing the balcony ceiling from the inside: foaming the cracks

In addition, the layer waterproofing material fits under the insulation of the loggia floor. For this purpose, special membranes or ordinary cellophane film are used. The material is laid with an overlap at joints of 15 cm and overlapping walls of 10 cm.

Waterproofing the loggia from the inside: laying the material

Waterproofing of the parapet and sides of the balcony is organized by laying a layer of material with inside, under a layer of insulation and Decoration Materials. Under exterior finishing Balcony vapor barrier is being installed. If this is a loggia with a parapet and concrete walls, then we do not do a vapor barrier.

Note:You cannot lay a second layer of waterproofing when insulating. If water somehow gets inside, it will not be able to dry, which will lead to an increase in the thermal conductivity of the insulation and its further deterioration.

Now let's start sealing. We use a special compound to go through all the joints and seams from the inside and outside balcony or loggia, which we previously waterproofed. This is done using a spatula. Don't forget about the glazing of the balcony, Special attention When sealing, we pay attention to the places where the frames are attached to the parapet and roof.

We seal the balcony after glazing. IN difficult places we use sealants in syringes

Work on sealing the roof of a balcony or loggia

If this is a balcony, then the roof is most likely based on a metal or wooden frame. Everything is simple here. First, we apply a compound from the inside to seal the joints between the sheets of roofing material, then we lay a layer of waterproofing material under the sheathing.

DIY sealing and waterproofing: roofing

We foam the joint between the roofing material and the wall of the house from the outside, and after the material has dried, we coat it with a sealing compound. Next, we attach a strip of tin or aluminum above this joint, and also seal the connection between the metal and the wall.

How to eliminate the possibility of a balcony roof leaking: sealing the joints with the wall

The roof of the loggia, if it is a concrete slab, requires preliminary organization of a slope from the wall. This is done differently than in the case of the load-bearing slab of an open balcony. Further actions will be like this:

  • We lay a layer of vapor barrier.
  • A layer of insulation if further insulation of the loggia is planned.
  • Let's do cement-sand screed and apply a layer of bitumen waterproofing.
  • We lay roll roofing materials - some type of roofing felt.
  • Now an additional layer of roofing material.
  • Using self-tapping screws, we attach the edge strip 50mm wide. It should grip the edge of the roofing material.
  • The upper edge of the slats is treated with bitumen sealant.

In cloudy weather you can see the balcony leaking and water flooding the floor. It seems that all our work has been done in vain. There is no need to despair, because everything can be fixed.

To do this, it is necessary to waterproof the balcony from the inside in parallel with its sealing. If you have a question - how to waterproof a balcony, loggia and seal it, in this article we will try to give you the most complete answer. In addition, you will find here not only answers to all your questions, but also detailed diagrams, as well as illustrations. First, let's figure out what waterproofing is and why it is needed.

What is waterproofing

Waterproofing serves to protect building materials from water flowing through defects in seams reinforced concrete structures. It is carried out by applying materials of various types to the surfaces of the floor, ceiling, vertical partitions of balconies, loggias. If waterproofing is not carried out correctly, water gets inside the room on the loggia, ceiling covering, after which active leaks begin.

Traces of water exposure on concrete structures clearly visible on open balconies (especially on upper floors). The edges of the balcony slab are destroyed, the junction of the load-bearing slab with the house is completely crumbled in places. Therefore, we immediately conclude that waterproofing an open balcony is necessary.

Sealing and waterproofing a balcony with your own hands can be done with a little construction experience. Let's consider the sequence in which waterproofing of balconies and loggias is carried out. Let us immediately note that waterproofing is carried out in parallel with sealing, which we will discuss below.

Waterproofing the balcony ceiling from the inside

We clean the top plate, which is the ceiling, from old plaster, we seal seams and cracks. We coat the entire ceiling with an antifungal antiseptic, for example, Belinka. We dilute a two-component polyurethane mastic (for example, Hyperdesmo), which forms a durable, elastic, seamless coating that does not require preliminary leveling of the base.

After applying the first layer, we reinforce it with a mesh with a cell of 5x5 mm. Apply the second layer perpendicular to the dried first one. Let it dry completely waterproofing coating and then we begin work on . We glue foam sheets to the ceiling and attach a vapor barrier film (for example, Izospan) on top of them. . But this work is carried out when the waterproofing and sealing of balconies (loggias) is completely completed.

Applying waterproofing to the loggia ceiling

Waterproofing of walls, vertical partitions of balconies and loggias

We glue foil polystyrene foam to the cleaned, antiseptic-coated walls - the most optimal material for vertical surfaces, which also serves as a vapor barrier for the balcony. We seal the joints between the sheets. Apply two layers of polyurethane mastic for waterproofing. Let's move on to processing the floor.

Waterproofing the floor

Summarize. From our article you learned how important sealing and waterproofing balconies and loggias are. It's not very difficult to do these jobs. The main thing is accuracy and attentiveness.

Regardless of what material the balcony is made of (reinforced concrete, wood or others), it is exposed to moisture, which, penetrating into the structure of the material, and then expanding when freezing or heating, destroys it. Balcony waterproofing is needed for every owner, private or apartment building. This measure helps to avoid premature destruction of the structure, and, consequently, delay the timing of major repairs.

Moreover, the fact whether the balcony is closed does not matter at all. The only difference is that the waterproofing of an open balcony must be more thorough due to the high level of load.

It is quite possible to waterproof balcony surfaces (loggias, terraces, etc.) with your own hands. The main thing is to follow the technology and use materials according to the requirements.

Types of waterproofing

The different structure and degree of load of the balcony (loggia, bay window, terraces, etc.) determines the division of waterproofing into types. The classification includes the following types:

  1. Molded type of insulation.
  2. Pasting type.
  3. Painting type.
  4. Impregnation type.

The cast type of waterproofing, as a rule, is used only for treating the floor of balconies (loggias, terraces). This is due to the difficulty of applying the composition to vertical surfaces. Besides this deficiency, we can also highlight low level strength, which suggests that this type of insulation can be used for rooms with a low level of load ( indoor balcony with hard flooring).

Advice! You can use a combined type of waterproofing: cast material for the floor and any other type for the walls and ceiling.

Pasted waterproofing is characterized by the use roll material to protect all surfaces of the balcony from negative influence moisture. It is one of the most common and sought after types. However, it requires careful installation and absolutely flat surface. Otherwise, the material may be damaged, which will affect the waterproofing of the entire balcony (loggia, terraces).

Painting type of moisture insulation is one of the most budget-friendly. However, it has its own characteristics. Thus, its use on a balcony in a wooden house requires regular re-applications. And under the influence low temperatures the material may crack, which will damage the waterproofing layer.

The impregnating type of waterproofing has high penetrating ability. This allows you to insulate the surface of the balcony (loggias, terraces) not only from the outside, but also at the structural level. Suitable for all surfaces, the only feature is the requirement: work on a balcony in a wooden house, carry out in dry and warm weather so that the impregnation is completely dry.

Materials for waterproofing a balcony

For each type of insulation of balcony surfaces (loggia, bay window, terraces) from moisture, there is an optimal material that is widely used in practice. Having chosen one of them, you can begin to directly provide protection from dampness with your own hands.

So, for the cast type of waterproofing, heated polymer is used. Having chosen it, it is worth remembering that it will not be possible to apply this type of insulation to walls.

Pasted waterproofing is usually carried out using polyethylene, which provides both reliable protection from moisture and a long service life of the surface. Waterproof paints are used for paint protection against moisture. paints and varnishes for internal or external work, depending on whether the loggia is waterproofed from the inside or outside. The same applies to the impregnating type of insulating materials.

As for the requirements for waterproofing materials, in this case, in addition to resisting moisture penetration, service life and resistance to other influences play an important role. external factors. The optimal waterproofing layer must be resistant to changes in air temperature, resistant to ultraviolet rays and mechanical factors.

Do-it-yourself waterproofing of a balcony

Waterproofing a balcony with your own hands is a voluminous and painstaking process, which, at the same time, does not require special skills in construction. When we're talking about on ensuring protection from moisture of all surfaces of the balcony (loggia, terraces), the procedure will include the following steps:

  • Waterproofing the floor.
  • Waterproofing of ceilings and walls.
  • Waterproofing of balcony canopy and roof.

All of these processes are preceded by preparatory work. Before proceeding with direct waterproofing of the room, it must be completely cleared of furniture. Then, the sheathing is removed from the walls, ceiling and floor, and all surfaces are leveled. If any defects are found, they must be eliminated using cement mortar(for floors and significant damage to walls) and putty (for walls and ceilings). The last step in the preparatory stage is to treat all surfaces with a primer to ensure better adhesion to the waterproofing material.

Important! Surfaces are treated with a primer for all types of waterproofing, except for adhesive. In this case, adhesion does not play any role.

Waterproofing balcony floors (loggias, terraces)

After all the preparatory manipulations have been carried out, you can begin to waterproof the floor. Depending on the selected material, the type and sequence of work will differ slightly. The general requirement remains for the absolute elimination of cracks and masking of all seams between the slabs and at the joints.

Then, waterproofing is applied to the balcony, cleared of dust and debris. When using rolled polyethylene, the material is overlapped on the walls (15 cm), then pressed wooden frame, into which, if desired, insulation is placed. All joints between pieces of material are treated with glue-sealant. Place on top of the formed waterproofing layer flooring(laminate, tiles, etc.).

When forming moisture insulation from other types of materials, a hot polymer, selected paint material or impregnation is evenly applied to the cleaned concrete layer. Concerning deep impregnation or painting waterproofing, you may need to make several applications, especially if we are talking about a balcony in a wooden house.

Waterproofing ceilings and walls

For ceilings and walls, it is best to use an impregnated type of insulation. This is due to the fact that this material has all the advantages for this type of work. Namely:

  • Provides reliable protection against moisture at the structural level.
  • Resistant to temperature changes.
  • Insensitive to ultraviolet rays.
  • Not damaged by mechanical impact.
  • Easy to apply.

Impregnation is applied to the cleaned and primed surface of the walls and ceiling. After it has completely dried, finishing work is carried out.

Waterproofing of walls is carried out by applying special impregnating compounds

When using paint-based waterproofing, paint and varnish materials, as well as impregnation, are applied to the prepared surface in one or two layers. Finishing work may not be carried out if colored paint is chosen as protection against moisture.

If the choice falls on rolled polyethylene, its sections are fastened along the perimeter of the ceiling and walls with wooden planks, and the joints and fastenings are treated with sealant. The final stage everything is also finishing work.

Waterproofing of canopy and roof

If the apartment on which waterproofing is carried out on the balcony is located on top floor multi-storey building, or we are talking about the terrace of a private house, additional care must be taken to protect the canopy or roof from moisture penetration. To do this, all joints and connections of the canopy or roof are treated with sealant. Then, hot roofing felt or roofing mastic is applied on top so that, under the influence of precipitation, the roof does not leak.

By spending time on ensuring high-quality waterproofing of the balcony, the owner of the home ensures not only a guaranteed dry room in all weather conditions, but also the preservation of the condition of the finish. Proper protection from moisture will postpone the date of the next cosmetic and major repairs for a long time.
