Waterproofing of a wooden bath. The floors in the bath in the washing room. We isolate the walls from moisture

Most building materials react negatively to high humidity, especially wood. Bath - one of the few buildings that are operated in the most difficult conditions, except high humidity and direct contact with water, a high temperature factor appears. Protecting architectural elements from the negative effects of high humidity is a complex of very important and mandatory construction measures. It is necessary to waterproof absolutely all elements of the structure, from the foundation to the roof.

Modern building technology and materials allow you to perform waterproofing work quite quickly and with a high degree of reliability. The implementation has wide selection materials various action and at different prices, which allows you to choose in each case best option with considering maximum number individual factors.

To facilitate the choice of the right decisions and make them more conscious, you should briefly familiarize yourself with existing species waterproofing materials and technologies of use. After small review let's move on to specific methods of waterproofing all elements of the bath: foundations, floors, walls, ceilings and roofs.

Types of waterproofing for a bath

All types of waterproofing materials are classified according to several criteria: method of application, place and time of use. According to the place of use, it can be external and internal, it is quite obvious that some materials are used for interior decoration and structures from the inside of buildings, while others are used from the outside.

In terms of time, waterproofing can be primary and secondary. Primary is done at the production stage construction works. The secondary one is used in case of violation of the initial hydroprotective characteristics of the primary one, as the planned operating conditions change or after the discovery of damaged areas.

Varieties of waterproofing by application method

For a bath, you can use all types of waterproofing materials produced, but each choice must take into account the operating conditions of building materials and structures and specifications isolation. What is waterproofing?

Coating

It can be one-component or two-component, produced in the form of mastics of various chemical compositions, most often based on modified bitumen or polymers. The thickness of the applied layer is 2÷4 mm, for some objects operated in particularly difficult conditions, the thickness of the waterproofing layer can increase up to several centimeters.

It is used to protect foundations from capillary moisture, rain and groundwater, in most cases it is used for processing concrete structures. It can be the main covering material for flat roofs.

Membrane waterproofing on the roof

We are sure that the knowledge gained will allow you to correctly select not only the types of waterproofing, but also the methods of its application. Consider the features of waterproofing of all bath structures.

For baths, ordinary polyethylene film or aluminum foil can also be used as waterproofing. Film - cheap, quite reliable material. Aluminum foil is the only waterproofing that can guarantee one hundred percent protection of surfaces from moisture penetration. But on one condition: all recommendations of manufacturers are taken into account. The disadvantages of foil are rather low physical strength and high price.

Bath foundation waterproofing

It is worth waterproofing the lateral elevated surfaces of columnar and strip types of foundations.

As a waterproofing, it is recommended to use mastics based on modified bitumen. If the bath has a drain water drainage system, then it is advisable to impregnate the concrete drain pad with sprayed or painted waterproofing.

Very important. The main attention should be paid to the waterproofing of the lower row of the log house. To prevent wetting of wooden structures between concrete and lumber, there must be at least two layers of roofing material or other resistant to mechanical influences material.

Bath floor waterproofing

Wooden floor coverings do not require any additional waterproofing. For them, the main condition for long-term operation is an effective ventilation system of the underground space.

There are projects with other floor coverings, in some cases it is used ceramic tile. Such floors must be separated from concrete or cement-sand bases. For waterproofing, you can use mastics or roll coatings.

When choosing a specific solution, one should take into account the features of the operation of floor coverings, the material of their manufacture and the presence or absence of heating systems. In some cases, it is recommended to use membrane waterproofing. But this is a rather expensive material, in most baths the floors are insulated with cold-use mastics, which can significantly reduce the estimated cost of the building.

Most attention should be paid to the steam room, in second place is the washing room. For waterproofing these rooms experienced builders recommend applying aluminum foil, only it can completely protect the surface from moisture penetration. Pay great attention to additional sealing of foil overlaps, the presence of even small gaps can cause significant trouble. In addition to foil, ordinary polyethylene film and non-woven materials are used for waterproofing walls.

These tips are for wooden baths, to brick or concrete requirements a few others. A slight increase in the relative humidity of these materials does not have a critical effect on reducing the life of the building. Waterproofing in them is carried out mainly to protect against excessive moisture. thermal insulation materials. Such buildings can be insulated with any of the above materials. Of course, the price range should also be taken into account.

If all roofing work is done in accordance with existing norms and regulations, no additional waterproofing is required. On the contrary, experienced professional builders can perform a complex of roofing works so high-quality that there is no need to lay waterproofing on the crate. Roofing and so will ensure the complete tightness of the roof. And the use of waterproofing causes an increase in the time and cost of roofing.

Conclusion

Conventionally, the waterproofing of the bath can be performed in two ways: passive and active. Passive methods are described in the article above. And the active ones should include a device for effective ventilation of rooms and underground space, water drainage, right choice materials of external and inner lining walls, implementation of measures for melioration of the construction site. You need to know that the durability of a wooden bath is 70% dependent on active waterproofing. structural elements buildings and only 30% of passive. Keep this in mind when building a bath.

A bath is a structure in which there is always high humidity. And this has a very Negative influence throughout the building and leads to its destruction. In order to extend the life of the entire structure to the maximum, waterproofing of the floor in the bath should be provided, which should be carried out according to the appropriate technology.

Types of floor waterproofing

Traditionally, floor insulation is divided into coated and glued. To perform coating waterproofing, the floor is covered in several layers with mastic, then it is covered with waterproofing materials which are produced in rolls. After that, the floors are covered with finishing materials. This type of insulation protects the surface from water ingress, but takes up an extra 6 cm of floor height. One significant disadvantage remains that such insulation will give off an unpleasant bituminous odor.

To make glued insulation, you can use armobitep, hydroglass, glass roofing material and polymer films that don't rot.

For use in a bath, a penetrating type of insulation is more practical. To do this, the floor surface must first be cleaned, treated with a primer, and after solidification, covered with a waterproofing agent.

Floor insulation

Often during the manufacture of the floor for the bath are used coniferous varieties tree. Because they retain heat well, they are the best choice for the steam room and dressing room. However, despite all the wonderful advantages of a wooden floor, it is susceptible to mold and decay and can soon become unusable. You can read how to get rid of mold. To exclude this, perform waterproofing.

A wooden floor may or may not leak. A leaky coating is in the event that water flows through the cracks in the floor, and if it does not flow, but leaves through a special drain hole outside the structure, then the floor is not leaking.

In order to protect the wooden floor in winter from frost, it is necessary to provide thermal insulation measures. This is done as follows - 5x5 cm bars are fixed under the logs, and rough boards are covered on them. On top of these boards, a polyethylene film is spread or roofing felt in two layers.

Materials for thermal insulation are laid on this flooring - glass wool slabs or mineral wool. You should not use expanded polystyrene, because it is highly flammable. Moisture-proof materials are laid on top of the heat insulators. Thus, you can protect the floor in cold weather.

However, to protect against the penetration of moisture into the draft boards, waterproofing must be done as follows:

  • We lay several layers of roofing material;
  • Coat the surface with bitumen.

After these simple operations, you can begin installation floor coverings. In such cases, it is preferable to use coniferous varieties of wood, because. they initially have resin and are more resistant to high humidity and decay. Boards for the floor in the bath must first be trimmed. Despite the existing water-repellent properties, holes must be made on the surface of the floor, which will contribute to the removal of accumulated water.

concrete pavement insulation

The floor in the bathhouse can also be made of concrete, both in the steam room and in the washing room. Such a floor has a service life of up to 25 years, while a wooden one is no more than 6 years. But even in this case, waterproofing of the floor in the bath must be performed. This can only be done when the concrete is completely dry.

A concrete screed 2 cm thick is made on the floor, and a material for waterproofing is covered over its surface. The surface must first be freed from defects and leveled. To begin with, waterproofing mastic is poured in several layers, and then waterproofing material.

If you make the waterproofing of the floor in the bath correctly, then you will provide for a long time reliable protection from exposure to moisture.

Video.

To provide comfortable conditions and hygiene standards the waterproofing of the bath is carried out in full without fail. Thanks to this measure, the floor, walls and ceiling in the room remain dry, there is no fungus and mold, and the insulation lasts longer.

How to do this, we will talk below and, in addition, as an addition, watch the thematic video in this article.

Waterproofing in the steam bath

Types of waterproofing

  • The simplest material that is used to protect against moisture can be called dense polyethylene film, although it is one of the components. But if we talk about the concrete floor, then this is perhaps the only thing that is needed there, that is, such a film acts as a cut-off, regardless of whether there is a heater there.

  • This material, which you see in the photo above, is very similar to polyethylene, only much stronger, which is very convenient for the same floor.. Such insulation perfectly fits under the expanded clay or crushed stone pillow, without breaking through the granules. It is also vapor-permeable, that is, the surface consists of granules in the form of funnels, which allow moisture to pass in one direction and not in the other, which is especially convenient for rooms with high humidity.

Advice. Given this feature of the material, you should be extremely careful when installing it - it is laid with the rough side to the insulation.
Thus, mineral wool or foam can release moisture that has accidentally entered there.
But the price of such an insulator compared to conventional cellophane is quite high.

  • Such paper is mainly used as a cut-off for insulation on, but can also be used as a do-it-yourself waterproofing of the foundation of a bath. But in this case, it is used for a partition between the tape and the wall, although it is much more convenient to use roofing material here.

  • And, of course, foil, whether paired with foamed polyethylene, or simply in the form of a film - such material closes the insulation on the walls and ceiling, and a lining or another is already attached on top of it.. Such insulation, among other things, also performs the functions of a reflector, as required by the instructions for arranging a steam room. Just do not assume that it reflects air or steam - aluminum film is able to reflect up to 85% of infrared thermal radiation that emits any heater or hot item.

Foundation

It should be borne in mind that the waterproofing of the foundation for a bath can be both horizontal and vertical, which, in fact, you can see in the top photo. This part of any building is most exposed to moisture, which occurs in the form of precipitation and groundwater.

Vertical protection for such buildings is usually made with molten bitumen, and from the bottom of the tape to the top of the base. But this is not always necessary, since it is important to take into account factors such as the regional climate (dry or damp) and the condition of the soil in a given area.

In addition to vertical, there is also horizontal waterproofing of foundations, which is often called cut-off or simply cut-off. For this, you can use any material, but, as noted above, it is the cheapest (although no less reliable) to use roofing material.

It is laid under the masonry or framing of the log house, and, if necessary, under the sole of the foundation (watery soils).

Floor

For the floor, as well as all waterproofing in the bath, it consists of a set of measures taken when pouring a screed or arranging a wooden floor. In the diagram you see how the screed is formed, only instead of concrete slab there may be ordinary soil on which a pillow of sand is poured. By the way, ceramic tiles on the floor are also almost one hundred percent barrier to water and steam.

Advice. If the floor is settled on the ground, then it is better to lay polyethylene under the sand cushion.
So the sand will remain dry and expanded clay or crushed stone will not damage the cut-off.
The edges of the film must be wrapped on the walls along the height of the screed surface.

The wooden floor in the bath also needs to be isolated, but do it in such a way that the boards do not lie on the film. The thing is that under the floorboards should be natural ventilation which needs space. This will allow moisture to evaporate better, which, in turn, increases the service life.

Walls and ceiling

As a rule, waterproofing the walls of the bath from the inside, just like the ceiling, is carried out in two stages - under the insulation and on top of it. A vapor-permeable or cellophane film is laid between the wall (bituminous paper can be used), and foil or foil polyethylene foam is already fixed on top of it.

Such a measure is necessary to protect mineral wool or polystyrene from moisture, which can penetrate from both sides - in the form of steam from the side of the bath or condensate from the side of the wall. However, in order to avoid condensation, the walls are insulated from the outside or simply made thicker.

Conclusion

As you can see, the question of how to make waterproofing in a bath is not so complicated in itself, and for this you just need to use the right materials. The main thing to remember is that do-it-yourself waterproofing of the bath should basically protect the insulation.

A bathhouse, a sauna, a steam room are functional auxiliary buildings with high humidity, and the waterproofing of the floor in the bathhouse determines its durability. wooden building in the country can be built on summer season when cracks are made in the floors for natural drainage of water. However, the capital structure on suburban area for a year-round visit, be sure to build according to all the rules, with floor insulation and waterproofing.

What is important to know about the floors in the bath?

The country bath is constructed from different materials, including cast walls and brickwork, but in many regions it is customary to build from natural wood. This is versatile material, but with an excess of steam and moisture, any wood is prone to rotting, mold and other fungal infections. In order not to have to redo everything in a couple of seasons, it is better to provide for competent insulation of the bath:

  • foundation;
  • floors;
  • walls;
  • ceilings;
  • outlets of all communications.

Water, even with a single flood, can damage the structure, especially when the building has constantly high humidity and water on the floor. Excess moisture destroys brickwork, reinforced concrete, wood and Decoration Materials. A primitive building with a specific microclimate can be built without much frills. But even if it is floor waterproofing in a stilt bath in capital construction, regarding fire safety and protection against bending, everything must be done thoroughly.

To bath a long period brought some positive emotions, it is important to protect all surfaces from destruction by moisture in stages:

  • waterproofing of the foundation and floors in all departments;
  • vapor barriers and wall insulation from the formation of condensate with waterproofing;
  • vapor barrier and waterproofing attic space or roofs.

The absence of these measures and a full-fledged outflow of water with the possibility of ventilation after using the bath leads to stagnation of the used water and rotting of materials. Nobody likes to walk on dirty water and slide on wet surfaces. A dry, insulated and clean sauna is hygienic, safe and comfortable. Therefore, about all protective measures, the wise House master should take care not yet at the design stage of the building, starting with the foundation, as well as with the waterproofing of the walls and floor in the bath.

When laying communications and arranging the floor in the bath, drainage should be provided in all rooms and a slight slope in the floor - as in the figure:

If everything is done correctly, then all the used water will go into a special hole. This is the simplest gravity system, but it does not exclude the waterproofing of the floor in the bath. The drain gutter must be made of stainless steel or polymers. The place where the feet stand should be insulated from metal, not too hot or cold. It is desirable that the drain funnel be away from the place where water procedures are taken.

Attention: When waterproofing the floor in a bathhouse, materials should only be applied to a dry surface, regardless of whether it is rolled or bulk materials with penetrating properties.

Varieties of waterproofing the lower surface

High-quality insulation and waterproofing of the floor in the bath is feasible only taking into account the features of the base and the type of water drainage from the room:

1. A continuous non-leaking floor with a drain made of traditional materials.

2. Leaking floor, lined with sanded boards with a small gap or with drilled holes where the outflow is expected. Cold floor with slots and drainage under the bath - only for the summer version.

Attention: When making a purchase of materials, it is important to make sure that there is a marking indicating the installation tolerance in wet room. They also prefer non-rotting varieties. conifers wood treated with an antifungal compound.

Properties of penetrating floor waterproofing

The simplest way to waterproof a non-leaking floor is to treat it with bituminous mastic on a smooth surface, after which it is lined finishing layer finishes. With this method, high-quality protection against moisture is provided, but there are some disadvantages, for example, the specific smell of the material, which disappears for a long time.

Under decking waterproofing used polymer membrane, glass roofing material, hydrostekloizol and other non-decomposing materials. The mastic is applied with a brush with an overlap of up to 10 cm on the wall material to make something of a waterproof pallet, on top of which wooden boards, tiles or other suitable flooring are laid.

Classical concrete waterproofing - effective method, but it is impractical for a small country bath. It is used in the construction of swimming pools and capital buildings or in the waterproofing of a concrete floor in a city bath.

Waterproofing with polymer-cement compounds is known for excellent adhesion, leveling of the treated surface, durability, and environmental friendliness. Seamless waterproofing guarantees the greatest effect, and it is suitable for any room.

Important: When performing seamless waterproofing, special attention is paid to areas where communications pass, opening a passage to the foundation.

Sometimes a leveling (self-leveling) mixture is used to level the floor, which provides perfect surface. It perfectly interacts with any type of penetrating insulation - polymer-cement, concrete or polymer-filled.

Features of waterproofing wood floors in the bath

Tip: Before waterproofing the floor in the bath, you must wait for the time interval after the foundation has set - to ensure the integrity of the coatings. It is better to combine all insulating processes with thermal insulation (expanded clay, mineral wool).

Wood is an ideal eco-material for a bath, as it is prone to fungal infections and decay. High-quality waterproofing of the wooden floor in the bath and impregnation of the boards protective compounds allows you to control these processes. This requires:

  • handle wooden logs for laying the floor of the bath;
  • lay the crate on the subfloor, including backfilling with drainage;
  • fill a timber up to 100 mm on the base and lay a layer of a film hydrobarrier;
  • fill expanded clay between the timber;
  • lay the subfloor;
  • complete the floor finish.

As the main insulating material use euroruberoid, membrane materials or aquaizol. The roofing material at the junction is welded or glued with hot bitumen. Between insulating layer and wooden deck be sure to leave a gap of 2-3 kg - for ventilation and to counteract the formation of condensate.

No less effective is the waterproofing of the concrete floor in the bath with the use of Hydroizol. In this case, sheets of plywood are nailed to a rough base. A polymer web is laid on this base with the ends of the segments superimposed on adjacent walls. Makes sense lower ends finishing board on the wall temporarily leave loose, and complete the process after the completion of the main work.

Features of waterproofing concrete floors

For those who do not know how to properly waterproof the floor in a bath over a concrete floor, it is important to take into account their specifics. Concrete is known for its reliability, coating strength and durability, but even in such a bath, waterproofing is done properly. When the concrete screed sets, they proceed to the arrangement of protection against the penetration of water under the floor, as is done with any other type of foundation.

In regions with a cold climate, frost is possible on the floor if there is no proper thermal insulation in the bath. At the same time, even rapid heating of the room is not effective. The use of flammable polystyrene foam is undesirable. A layer of waterproofing must be applied over the thermal insulation layer to protect it from freezing in winter.

On a flat rough surface of the floor is applied concrete mix, aligning the base as much as possible so that there are no distortions when finishing gender. 2-3 layers of waterproofing mastic are applied to the cleaned surface, on which roll materials- a thin membrane or a denser roofing material.

The construction hair dryer is soldering the seams. A reinforcing mesh is applied over the waterproofing and a layer of concrete screed is again made. At the same time, it is important to ensure that you do not stain the wall decoration using masking tape. On top of the screed layer and waterproofing of the floor in the bath, non-slip porcelain stoneware or other suitable finishes are laid under the tiles.

Attention: If the bath is a typical log house with concrete base, then all work on heat and waterproofing is done after the primary shrinkage of the wood. That is, the main work is carried out 1-2 years after completion draft stage construction, but before finishing.

Waterproofing the floor with liquid glass

The process of processing the bath floor with liquid glass almost does not differ from a similar technology in the silicification of concrete structures. This is the most economical method, and it takes less effort and time. Using liquid glass for waterproofing the floor in the bath, we make an analogue of penetrating insulation, but with a different material. This substance, when applied to reinforced concrete, foam concrete, concrete or bricks, gives a crystalline base to fill a solid base.

Liquid glass resembles molten rubber or resin, and this semi-liquid medium forms a waterproof layer. After pouring the foundation and rough preparation of the floor, this viscous transparent mass eliminates the penetration of air and moisture. The basis of such waterproofing is calcium (sodium) silicate with the addition quartz sand and soda. The molten and solidified mass is ground into powder, which is then diluted to a certain consistency. The main properties of the viscous mass after hardening:

  • water repellent;
  • antiseptic;
  • chemically neutral;
  • fire fighting;
  • antistatic;
  • high adhesion.

The service life of such waterproofing is small, about 5 years, the silicate mass is prone to self-destruction. The thicker the insulation layer, the longer it will last, especially if covered with a protective paint.

It is not worth doing a lot of solution at a time - going fast crystallization. After half an hour it seizes, and nothing can be altered and added. It is desirable to have the skills to work with the application of liquid building suspensions, so that in half an hour, until the liquid glass has lost its properties, it is possible to process a significant floor area. For beginners in repair, such high-speed processing is difficult. The less solution is prepared, the easier it is to manage it. But this waterproofing has advantages - the ability to work in conditions of high humidity, penetrating into cracks or holes treated with other materials.

Experts have learned to add a liquid silicate mixture to other solutions in order to obtain new properties. For example, often liquid glass is poured into a solution of cement, in a ratio of 10:1. Here it is important not to violate the ratio, because if the proportions are violated (in the direction of increasing liquid glass), the mixture immediately “dubs”. But this property can be used to quickly fill suddenly formed cracks or cracks in the foundation and floor of the bath.

Attention: If the proportions are violated building mixtures excessive crystallization can tear the seams and joints of the surfaces. The crystalline structure is also prone to cracking with a sharp impact or other mechanical stress.

If ready-to-use liquid glass is stored in a sealed container, it does not lose its properties even with temperature changes. The solution first penetrates into all the cracks, after which you can add a little more to the failed areas. When the liquid glass dries (hardens), after about half an hour it is time to apply the next layer of insulation.

It is better to vacuum the cleaned surface to increase the adhesion of the solution to the screed. If there is any doubt about the integrity of the coating, it is better to additionally clean the surface with a spatula and a stiff brush to remove all unstable particles. After that, the prepared liquid glass is applied in a small layer with a brush or roller, and after crystallization, the process is repeated.

Specialists apply waterproofing with liquid glass in uniform strips, for example, parallel to the wall remote from the door. On a small area of ​​\u200b\u200bthe floor, the solution can be poured in portions, spreading over the surface with a wide spatula or other tool. It is convenient to work with a wide paint spatula on a long handle or a spiked roller nozzle.

Important: During application, air bubbles may form in the solution, which must be eliminated.

The finished insulation layer is removed at least 3-5 mm. Since the material is transparent, it is important not to miss the "bald" areas. The finished surface after complete crystallization is covered with a protective layer of polyurethane or acrylic varnish.

Special attention deserves the "warm floor" system in the bath, which is best entrusted to specialists. However, all work on the arrangement of high-quality waterproofing can be done independently. When working with any type of waterproofing, it is important to observe safety precautions - work in protective clothing, ventilate the room well.

The most popular material for building a bath is wood. The tree is great for a steam room, but quickly rots and becomes moldy from excess moisture. For the safety of the material, high-quality waterproofing of the floor should be made. The process should begin after shrinkage of the foundation so that the coating does not deform.

Wood floor waterproofing:

Properly done waterproofing a wooden floor includes:

    Processing floor slabs in the bath.

    Laying the crate on the surface of the subfloor sprinkled with drainage.

    Stuffing the timber on the base of the floor and laying the moisture-proof film.

    Backfilling of expanded clay between the timber.

    Subfloor laying.

    Exterior finish of the bath floor.

Roofing material, aquaizol, membrane-type materials will serve as an insulating material. All joints of roofing material should be boiled or covered with hot bitumen. A gap of two or three cm must be left between the wood flooring and the insulation so that condensation does not form and ventilation is improved.

Concrete floor waterproofing:

The concrete floor differs in reliability, durability and durability. But in this case, waterproofing of the bath floor is also necessary. Before starting work, you need to make sure that the concrete screed is completely seized.

In the absence of proper thermal insulation in cold regions, frost forms on the bath floor. It is not possible to get rid of the ice even with the rapid heating of the air. Expanded polystyrene should not be used due to the easy flammability of the material. Waterproofing must be laid on the heat-insulating material to prevent freezing in winter.

Concrete must be applied to the leveled subfloor, leveling it so that there are no distortions when finishing the floor. After setting, two or three layers of moisture-proof mastic are laid on a clean surface. Then the roofing material or membrane is rolled on top.

Is taken building hair dryer, and the seams are soldered. Then a reinforcing mesh is laid and a layer of concrete is laid again. You need to be careful if the wall decoration is done - use masking tape to prevent smearing of the surface. Porcelain stoneware or other finishes are laid on the concrete screed and the waterproofing layer. Please note that when wooden frame baths work should be carried out after shrinkage of the walls. This process takes from one to two years.

Liquid glass for waterproofing:

The treatment of the bath floor with liquid glass is almost identical to the silicification of concrete buildings. The method is cheaper and simpler than others. When using liquid glass for moisture insulation of the bath floor, we imitate penetrating insulation. Liquid glass, when it hits concrete products or bricks, creates a crystalline substance, filling a rigid base.

The consistency of liquid glass is similar to melting rubber, which contributes to the creation of a moisture-proof layer. Poured onto the foundation and subfloor, the mass forms a barrier to air and water.

Liquid glass consists of calcium or sodium silicate, soda and quartz sand. After the substance hardens, the mass has the following properties:

    waterproof;

    antiseptic;

    neutral chemically;

    refractory;

    antistatic;

    with high adhesion.

Such waterproofing serves only 5 years, because the substance has the property of self-destruction. It is worth noting that at thicker layer insulation lasts longer. The substance will last even longer if covered with a protective paint.

You need to know that liquid glass hardens very quickly, so you need to prepare the solution in small batches in order to have time to fill it. Half an hour after pointing, the glass will harden and nothing can be redone.

Professionals have learned to mix liquid glass with other substances and have received new materials. If you mix 10 parts of water glass and 1 part of cement, you get an excellent mixture for repairing foundation cracks. It is important not to violate the ratio, otherwise you may not have time to fill in - the substance will harden very quickly, and in the worst case, the mixture can break the foundation at the place of pouring. Liquid glass can be stored ready-made, but only in sealed containers.

For better contact of liquid glass with concrete, you need to vacuum the surface. Apply the substance in equal stripes, evenly distributing over the surface. When working with liquid glass, bubbles can form in the solution, which must be disposed of.

The result should be a uniform layer of waterproofing with a thickness of 3 to 5 mm. The layer is transparent, it is important not to miss uncovered areas of the floor.

After drying, the liquid glass waterproofing layer is varnished.

When working with any waterproofing, it is important to follow the safety rules and regularly ventilate the room.
