Waterproofing under the tile with their own hands. Waterproofing bathroom under the tile - what is better to choose from materials waterproofing over the tile in the bathroom

Tile laying technology in the bathroom provides for pre-protection of building structures from moisture.

For such tasks, manufacturers offer whole line Materials.

We will look at their strengths and weaknesses in this article, the theme of which is the waterproofing of the bathroom under the tile: what is better?

Facing the ceramic tile made by all the rules - water does not miss. But since it is not monolithic, the probability of depressurization is quite high. Moisture penetrates for a number of reasons:

violated technology finishing work;
the low-quality grout is applied;
Because of the mechanical exposure, places turned out or microcracks appeared in it;
there was a flow at the points of the passage of communications, corners or other vulnerable areas.

In an apartment building in the absence of waterproofing on the floor, due to the flood, it will be necessary to make repairs not only in itself, but also in the neighbors below. But dangerous and insignificant leaks.

Waterproofing bathroom under the tile

A small amount of water is enough to germinate the dispute of mold and the development of fungus. These microorganisms are applied double blow:

poisoning with air disputes and toxic discharges, providing this negative impact on the health of residents;
use mineral compounds as food from building materialAs a result, he is destroyed.

Even if the laying of tiles in the bathroom is entrusted to an experiencing and conscientious master, pre-waterproofing of building structures is necessary.

Types of materials

Waterproofing materials are available in various versions:

polymer membranes and films;
rolled bitumen materials;
mastics;
polymer plasters;
penetrating compositions.

Each of them has the characteristic advantages and disadvantages.

option of using waterproofing in a bathroom under the tile in the repair of the room

Polymer films and membranes

The thickness of the films is 0.2 mm. They are made of polyethylene or polypropylene.

Membranes Topic: from 0.8 to 2 mm. Made from polychlorvinyl or EPDM synthetic rubbers and SKEPT.

The films and membranes are glued with mastic, some are equipped with a sticky layer, a closed celluloid film.

The advantage of these materials is a significant sizes of cloth: the width of the roll can reach 15 m, length - 60 m. This allows even a spacious bathroom to make a seamless waterproofing coating.

Bitumen Based Roll Materials

The addition of polymers provides such advantages:

the service life increases;
the possibility of laying by the catchment method appears.

Instead of low-strength cardboard, a non-burning base is applied: polyester, glass cholester or fiberglass.

This technology produces many materials:

bikrost;
rubext;
glassizole;
fiberglass, etc.

A common source name for all - EuroRuberoid. Rolls are narrow - 1 m wide.

Mastiki

Divided by 4 varieties:

Polymeric based on MS polymers: butyl rubber, etc. The most durable and eco-friendly: do not contain bitumen and solvent. Disadvantage: High cost.
Bitumen and bitumen-polymer (with the addition of latex, rubber crumb, polyurethane and other polymers). It is cheaper, but less durable and contain solvents (distinguished harmful substances).
Polymeric based acrylic. Cheap and short-lived.
Epoxy.

The latter are designed for outdoor work, because they are not suitable for the bathroom.

Polymer plasters

Made on the basis of a non-shy or expanding cement with the addition of latex, other polymers or epoxy resin, bitumen emulsions and pastes. In the role of sealing components are chlorine iron, sodium aluminate, nitric acid calcium.

Penetrating composition

Abscribed with a porous surface and act inside the pores. Penetrating waterproofing is divided into two varieties:

penetrating Forms: Poores are clocked;
hydropobicators: leave pores open, but wet their walls, eliminating the capillary effect.

A concrete covered with a hydrophobizer remains vapor permeable, from direct exposure to water such insulation does not protect. It is used to process walls outside.

For the floor under the tile

With gunpowder or random splashing - water is assembled on the floor, therefore, the most reliable waterproofing materials are placed here and besides several layers. These are films and bitumen-polymer rolled materials.

For walls under the tile

On vertical surfaces, primarily take into account the adhesion of the waterproofing material.

The adhesiveness of the films and membranes is low, therefore, they do not fit the tiles to be covered. Apply the coating (most often), plastering and penetrating compositions - they are characterized by high adhesion.

In the direction of waterproofing materials under the tile are prescribed for walls and gender.

Technology application

Thorough knowledge of material application technology is a prerequisite for effective and durable waterproofing. With incorrect installation, it, regardless of the quality and reliability, the protection against moisture will not provide. Consider the methods of installation of the listed varieties of waterproofing.

Claimed rolled materials

The lower layer of the tight bitumen polymer material during heating softens and becomes sticky. A couple of days before the start of work, the rolls rolled so that the panels were flying away. In the absence of free space, they are rewinding so that the material is bent in the other side.

Installation order:

The surface of the floor is purified from dust and treated with bitumen primer (primer).
The roll is rolled on the floor and laid into the correct position. Syclamp, cut and twisted on both sides to the middle, so that we turn out two rolls.
Heat the burner the lower surface of one roll to the state of the plasticity and the little breath is unwinding it, pressing the material to the floor and rolling it with a roller.
Similarly, the second roll is applied.
The next cloth is laid with an overlap at 10 cm.

Claimed rolled material

Floor waterproofing is made at a height of 30 cm. The burners of two types are used:

gas;
gasoline (soldering lamp).

Gas equipment is more convenient, but due to explosion hazard, it requires a skillful circulation. Newbie is better to use the soldering lamp.

Overheating of the material leads to a deterioration of its quality, because the impact of the flame should be moderate. Convenient materials that have upon reaching optimal temperature Figure appears on the surface.

Coating

Refractory waterproofing include mastic and polymer plaster.

Mastic is applied in this order:

From the processed surface, the remains of the old finish are knocked down and dust believes.
Then it is ground. The primer differs from the main coating only by the consistency - it is more liquid. This allows it to penetrate the smallest pores and microcracks, thereby improving adhesion.
In accordance with the instructions, the main composition is prepared if it is supplied in a two-component form. The period for which the mixture should be applied (vitality time) is limited, so they prepare it immediately before applying and in the amount that the master is guaranteed to have time to spend over this period. "Living time" indicate the packaging.
Apply a coating waterproofing to the surface. Two methods are used: manual (liquid compositions are applied with brush or roller, pasty - spatula) and machine (apply sprayers, superchargers, etc.).
Corners are sampled by a mesh with a hydraulic protection coating.
Apply the second and subsequent layers, capturing the grid pasted into the corners. Multilayer styling increases the reliability of the coating and is almost always applied. The time of applying the next layer in different mastic is different. Some require to wait for drying and rejection of the previous layer, others are only partial collapse, others are applied immediately. In case of non-compliance with the instructions, the quality of waterproofing will suffer.

Caution isolation

Mastics from MS polymers can be applied to a dry surface without primer.

Polymer plaster are applied as ordinary cement-sandy solution: With the help of Kelma, Hacker and Graters. The thickness of the layer is 2.5-3 cm. In areas of the large area, machine applying is used - torturing.

For 20 days after applying, the solution is moisturizing. It is important to carefully study the instructions: some varieties need to be moistened 12 hours after laying.

Oblaika

Some polymeric films, membranes and bitumen-polymeric materials are equipped with a sticky layer, a closed film.

This makes the laying technology extremely simple:

Purified from dust surface is ground.
Rolled the roll and put it in the correct position, cut. Next again fold.
Removing the film from the adhesive layer, grinding the material, pressing it to the floor and rolling the roller.

Similarly glue the second cloth, observing the nest of 10 cm.

Impregnation

The penetrating waterproofing is applied as:

Concrete or plaster moisturize. Water acts as a reagent: it forms with the main component of impregnation, crystallohydrate is a solid, closing pores in solution.
The scroll brush is applied to the surface of impregnation.
Waiting for the beginning of setting the composition, it is moisturized and applied the second layer.

During the 20 days, the treated surface is periodically moistened or covered with its polyethylene film, limiting the loss of moisture.

What waterproofing under the tile is better to choose for the bathroom

For work in the residential premises, materials that do not distinguish harmful substances are preferred. Bituminous mastic containing solvent and bitumen-polymeric filtered materials that emit sharp smell are not related to such. More environmentally friendly, self-adhesive rubber membranes (PVC analogues are excreted by harmful gas chlorvinyl) and mastic based on MS polymers that do not contain bitumen and solvent.

Also, for internal works, coating waterproofing based on cement with additive polymers is suitable.

Waterproofing device - the most important stage Finishing works in the bathroom. The waterproof barrier will protect building structures from the impact of moisture and the development of mold during the deployment of intercutric seams and will prevent the flow of water during flooding in the premises. After acquaintance with the outlined recommendations, the choice and laying of the material will not differ.

The bathroom in any house is a room with the most high levels , It is in it a warm steam accumulate. Lack of high quality will lead to the appearance molds mushrooms and the emergence of an unpleasant odor. The most important action when performing facing works is the waterproofing of the bathroom under. What is better to choose telling the analysis of options and their characteristics.

The use of high-quality and reliable waterproofing materials will allow any design of the tile finish, which will serve for a long time.

This method of finishing can be protected from moisture and appearance. wet spots. Also increases the service life of the finishing flooring of the floor and walls, and prevents damage to the base from concrete. For the device in the bathroom, you will need the most moistureproof and durable materials.

Waterproofing of the bathroom under the tile: What is better and what method is preferable?

For solo floors in the bathroom requires strong materials. On the basis of the floor, such a coating is made with a certain intercession on the walls. When finishing walls, such protection is necessary in the area, and other plumbing devices.

When choosing an option for waterproofing, it is worth considering the following criteria:

for the bathroom, this is not required;
the price of material options that can be very different;
the technology of the installation process should not be too complicated.

Mixtures for protection against humidity are one-component, which are bred by water, and two-component, which are created using a polymer emulsion.

Varieties of waterproofing floor in the bathroom under the tile

When viewing the material for waterproofing floor in the bathroom, it is worth considering that the main type two. This is a coating, presented by mastic, various pastes and solutions. And the second - the inlet consists of film coatings, a roll type.

Helpful information! If the room is too low and you cannot raise the floor level, then impregnations are recommended, which are liquid compositions. They are distributed on the basis and form a special film that protects against humidity.

The diagram shows where the waterproofing layer passes

Foolish waterproofing

It is possible to prevent moisture with a coating waterproofing for the bathroom under. The following types of liquid coatings are used:

cement-polymer products are a versatile agent. This mixture is excellent and characterized by excellent adhesion;
bituminous polymer mastic have special latex fillers, organic solvents and plasticizers;
bitumen waterproofing is considered to be a budget option;
to modern materials Applies acrylic mastic.

Modern options are characterized by excellent waterproofing properties and ensure full-fledged protection against humidity. The main advantage of such materials is the content in the composition of fillers and plasticizers, which give the material more elasticity and strength. Such a coating is characterized by the simplicity of the device, long service life, as well as the floor before processing, do not need to be thoroughly aligned.

Applying such waterproofing requires special execution techniques. Before work, you need to use the floor well. Then the base is stuffed with the use of roller. So that the fluid does not penetrate the space between the floor and the walls, they should be covered with a special hermetic ribbon. For distribution of mastic throughout the area, rollers are used, and brushes are used for hard-to-reach areas.

Helpful advice! After applying protective coating You need to leave time for graze. At the same time, the room should be played and watching so that dust does not penetrate the processed area. It is impossible to attack on the floor.

Incineural option

Solving what to choose the waterproofing of the bathroom under the tile and choosing that it is better to apply, it is worth trying the inlet type of moisture insulation. Roll type materials are different. To create a focusing method, a gas burner is used, so it can only be used in the room where no one lives. It is melted with bitumen, which highlights a resistant smell. It is better to use self-adhesive and reinforced fiberglass hydroisoles.

This species Isolation is made in rolls

Such option is suitable for premises of typical sizes and equipped. Waterproof waterproofing It is considered a budget option, but requires some skills in construction business. With this method, you need to pay attention to the places of floor joints with walls.

a surface is prepared on which there should be no cracks, pits or tubercles;
the surface is cleared of garbage and is well drunk by primer from bitumen;
according to the measurements made, the material is cutting. At the same time, it is worth making the walls on the walls of 20 cm;
after laying the coating over the entire surface, you can walk the roller to remove all bubbles;
void and joints need to be treated with bitumen-based sealant.

If the installation of pipes is performed, they are covered with a special hermetic composition in places of contact with a layer of waterproofing. At the same time, the pipes are placed in rubber sleeves. After installing the waterproofing, a screed is made.

Plastering

Plaster waterproofing walls of the bathroom are popular. For this option, products with polymer components are used, which improve the characteristics of the materials. High-quality options include brands of brands Cerezit and Knauff, which is recommended to use in the bathroom. When selecting waterproofing, it is worth a preference to a certain company's products. The KNAUF contains a synthesized latex, which gives coating more elasticity.

Before the distribution of the mixture, the surface is cleaned and processed, and emptiness and sections of connections are sealed with a special tape. Then the composition is prepared and is distributed on the harvested base. Plaster solutions are applied using rollers. After drying, still the layer is distributed in the opposite direction.

Lata waterproofing

Planning how to make waterproofing in the bathroom, it is worth trying a cast option. Installation is performed by a cold or hot spill.

Asphalt concrete or bitumen is used as a hot waterproofing material. Such coating is characterized by increased resistance of bending, reliability and elasticity. The fill is made on a predetermined surface, where the sealing of joints and seams was carried out. Such a method is applied in private homes, and not in apartments.

The coating is performed in several stages:

the surface of the floor is cleared, and the cracks are filled with a special sealant;
the floor successes with gas burners and;
primer with hot bitumen;
the area is highlighted by the formwork;
waterproofing is heated; The hot solution is evenly poured and distributed with the help of Raklie.

Several layers of such a fill can be used. For apartments, cast waterproofing of the bathroom under the tile is also used. what better suitable For this, the advice of professionals will be prompted. Cast coating can be made in a cold way. It uses liquid glass or rubber.

Liquid rubber

One of the effective options for liquid waterproofing for the bathroom is liquid rubber. It is made from the addition of polymer and bitumen. Calcium chloride is used as a fixing substance.

The durable coating is applied in different ways:

the bulk technique is made without any equipment, and allows you to fill small cracks;
spraying is considered more laborious technique, as it requires a special device that helps to apply a pressure solution;
painting equipment is performed as well as the usual coating option.

After processing, a film is formed that protects the surface from humidity.

Overview of some species and cost

Features Technology

A special approach is required for wooden coatings. Wood quickly absorbs moisture, so it is necessary to isolate this coating well. This uses a two-component waterproofing solution. For this, the liquid rubber is mixed with the activating component. The resulting composition is applied to the surface using a roller. After the layer is driving, the second layer is applied.

If you need to remember that the adhesive properties of such sex are low, therefore, to increase the clourage, it is necessary to perform with the laying of arms.

When using any waterproofing, first executed preparatory work. Old paint is removed from the walls, the floors are aligned and the dust and garbage is cleaned. Before laying waterproofing, you do not need to make perfectly smooth floors. Small irregularities will cover the waterproofing layer. Alignment should be done with significant height differences. After clearing the surface, the floors are ground in several layers. The primer composition is distributed using roller with smooth strokes.

Even with coating waterproofing, additional processing of angles, joints and connections is required. In this case, all the gaps and joints are eliminated with a hermetic ribbon, and plugs from rubber are put on the pipes. This type of protection against humidity can be made independently. Dry mixture is divorced by water or polymer emulsion. Finished mastic should resemble liquid plasticine.

Masty dry during the day. This time on the floor can not walk, shed water or put any items. After 24 hours, the finishing coating is made.

High-quality waterproofing will allow not to worry about the accumulation of moisture and leaks. Increased humidity will not harm such a finish. And even with a small flooding - water will not cause much damage.

The atmosphere of the bathroom is characterized by high humidity. In addition, there is a great risk of flooding the neighbors in the event of an accident on water supply communications or failure of water treatment mechanisms.

Therefore, the issue of bathroom waterproofing is extremely relevant. It is necessary to protect the material of the interhesive overlap from moisture and the unpleasant consequences that it causes.

These are negative consequences as:

general dampness in the bathroom;
formation of mold and fungus, spoiling views of the bathroom and extremely harmful to people;
the appearance of unpleasant odor;
detachment of the finishing of walls and floor;
destruction of overlap designs.

Materials for waterproofing floor intended under the tile

All materials used for the floor waterproofing device are divided into the following types:

rolled calain insulation;
coating isolation - paste, mastic, liquids;
penetrating insulation for impregnation of concrete base;
hydrobarmers on a polymer or rubber basis;
dry cement insulating mixtures intended for independent dilution with water.

For the most part, the two first types of waterproofing are used to prepare the floor of the bathroom - inlet and coating.

Standard bathroom with low moisture level and finishing coating from small size tile is better isolate using roll Materials. To do this, you can use well-familiar only referencer, but it is better to give preference to modern materials based on fiberglass and polyester - such as isoelast, eco-plastic, bridgeoplastic, isoplast.

This method requires careful preparation of concrete base:

it should not have drops more than 2 mm;
concrete should be completely dry.

The base needs a preliminary application of primer representing a bitumen emulsion. And the process of rolling insulation stickers itself requires great accuracy. This method is good in that the floor level is practically not changed, since the thickness of the inlet layer is about 1 mm. Floor facing tiles can be carried out in a day after installation of waterproofing.

It can be purchased both in the finished form and in the form of a dry powder, which will have to be prepared independently. Such insulation must be applied at least 2 layers with an interval of at least 6 hours. The second and subsequent layers of isolation are applied perpendicular to the previous one. This allows you to fill in the composition even the smallest cracks and spaces. After applying the last layer, it is necessary to take a break for at least 24 hours and only after that you can finish the floor with tiles.

It should be borne in mind that the floor level of the bathroom should be 50 mm below the floor level adjacent to room.

This is done so that in the event of a leakage of water immediately did not go to the neighboring rooms, where the floors do not have waterproofing.

The initial stage of any work in the bathroom is the creation of waterproof "trough". To do this, before the waterproofing device, it is necessary to seal the joints between the floor and the walls of the room. In older panel houses They can even be through. For this purpose, you can use mastic or high-quality sealant.

To perform work, the following tools will be needed:

a vacuum cleaner;
metal brushes or grinding machine;
toothed spatula;
construction knife - for cutting roll material;
gas-burner;
foam roller or painting brush.

Preliminary preparation of the foundation:

with the help of a vacuum cleaner, it is necessary to carefully remove dust;
if the floor has oil stains and paint residues, they also need to be removed using non-aggressive chemicals;
the surface of the floor must be seized - this will allow to align the surface and make it smooth;
then the surface must be dried and spent again;
all cracks and irregularities of a depth of more than 5 mm must be lined with cement mortar;
the floor surface is wiped with a damp cloth and dried;
dry surface is treated with deep penetration primer - it is better to use a brand suitable for use in wet rooms.

The primer layer will finally fill all the minor irregularities and improve the adhesion of the base.

Isolation of this type can be applied and self-adhesive.

The weaving material requires heating the adhesive layer using a burner.

In this case, the bitumen material highlights a rather strong smell, which requires the device of an additional layer of screed over isolation. At the same time, the level of the floor can be higher by 2-3 cm, which is undesirable.

Therefore, it is better to use self-adhesive rolled insulation:

The roll is rolled on the floor and cut a piece of the required length from it. It must be longer the floor section by 30-40 cm. It is necessary so that the excess lengths can be started on the walls.
From the wrong part of the sliced \u200b\u200bpiece, you need to remove the protective film and gently put on the placed section of the floor with the flax on the walls.
For a better gluing of the material to the base, it is rolled in a heavy cloth.
The following pieces of insulation are placed in the same way, observing the nesting of neighboring pieces of at least 10 cm.
The seams and joints of the adjacent bands must be wrapped in mastic.
After her pouring, the surface must be acroved again.

This method has its pros and cons who need to know.

The advantages of rolled isolation are:

low cost of materials;
high heat resistance of the insulating layer;
simple installation.

Among the disadvantages can be noted as follows:

unpleasant smell of bituminous materials;
complexity in the process of the joints of the joints;
the inability to use in warm floors.

Technology Floor insulation Device

Most often for these purposes the following materials are used:

Bituminous rubber mastic based on an oxidized bitumen, an organic solvent and rubber crumb. It has a good adhesion with concrete, but its properties are manifested mainly on fibrobetones.
Bituminous polymer mastic - has as part of plasticizers and latex filler. Professional repairmen are very popular because it has an excellent adhesion to concrete and is very strong.
Acrylic replacement waterproofing composition - the latest generation materials. Very plastic, durable, environmentally friendly and do not smell. Therefore, at present, their use is becoming increasingly wide.

The process itself is simple, but requires great accuracy:

With the help of a painting brush or roller, the composition is applied to the floor and walls to a height of 20 cm.
After installing each layer, it is necessary to wait approximately 24 hours before applying the following. Usually grabs three layers.
After the second layer on the surface, it is better to put the reinforcing glass tube, which is then covered with the last layer of insulation.
If there are places in the floor of the floor of the floor, it is necessary to use special cuffs, which also wake up mastic.
While the mastic dried, you can sprinkle with fine dry sand. This will improve its adhesion with tiled glue.

This method is very good for premises with a complex geometry, where the markup and the sticker of rolling materials may represent some difficulties.

simple installation;
relatively low value of the material;
good adhesion with concrete base;
resistance to the effects of chemicals;
the formation of a practically monolithic waterproof layer.

The disadvantages include:

toxicity of materials requiring the use of protective funds while working with them;
low frost resistance;
not too high strength in mechanical impacts.

Each of these methods of the bathroom waterproofing device can be performed independently. For due results, it is necessary to carefully examine the instructions for using the material and strictly observe the recommended technology of work.

The bathroom is one of the most wet rooms, both in an urban apartment and in a private house. Therefore, the floors in the bathroom, regardless of the material from which they are completed, need high-quality isolation, otherwise water leaks are possible through the slabs of overlappings, the formation of fungus, mold, as well as gradual destruction of structures.

Types of waterproofing

Materials for waterproofing floor are:

Inlet with waterproof impregnation, produced in the form of rolls;
Coating in the form of mastic, as well as pastes, liquids on a different basis;
Dry mixes for water breeding;
Penetrating hydraulic protection for the impregnation of concrete;
Hydrobarians on a rubber or polymer basis.

All types of waterproofing have their own characteristics that determine the scope of their application. In the bathrooms most often used inland or coating materials based on bitumen, rubber or polymers.

Waterproofing floor in the inlet way

Rolled materials on a bitumen basis, improved polymers, with a reinforcing layer of fiberglass or synthetic materials. They are floating, requiring heating when laying, and self-adhesive. For the bathroom it is better to use rolled materials with a self-adhesive basis, since the floodplain requires applications gas burnerthat the apartment is not always convenient and done. In addition, when heated, they allocate a strong smell of bitumen, which does not destroy from the bathroom for a long time.

Concrete floor coating technology with self-adhesive rolled materials

Paul equalizes, eliminating cracks, depressions and hillocks. The height drop should not be more than 2 cm. Sweep it with a brush and vacuum.
The draft floor is covered with bituminous primer, allow it dried.
Cutting a rolled material along the floor length, leaving the margin on the walls of at least 15-20 cm on each side.

Place the stripes on the floor, whileking them to the brass. The laid rolled material is thoroughly rolled by a solid roller for removing air bubbles and better gluing. The joints are additionally missed by sealant.

In the joints and around the pipes, waterproofing should be stacked especially carefully. The pipes additionally need to be isolated using rubber seals, and their places of fitting them to waterproofing are additionally marked with sealant.
On top of the roll material immediately after its laying, you can perform a concrete screed, and then lay the finish coating. As a finish of such a floor, the tile is most often used.

The need for a device of a screed increases the complexity of the inlet waterproofing method of the floor in the bathroom, but in general this method is cheaper. If warm floors are performed in the bathroom, and the tie device with a thickness of at least 5 cm is meant in any case, the floorproofing of the floor in the vigorous method is more appropriate. A reinforcing polypropylene fiber can be added to the screed to increase its strength.

Caution waterproofing floor

With the development of technologies and the appearance on the market big choice Materials for coating waterproofing of the floor, it gradually displaces the calene. It is performed using mastic of various composition: bitumen-polymer, bitumen-rubber, cement-polymer. The mastic includes various fillers and plasticizers, due to them increases its elasticity and strength. Fillers in mastic can be in the form of fibers or crumbs. Most of the modern mastic also includes components warning the appearance of fungus and mold.

Most of the manufacturers also produce primers having increased adhesion with floor and mastic on the same basis. When performing waterproofing, it is better to follow the tips of the mastic manufacturer and use the primer specified by them.

Technology of coating of coating waterproofing on concrete floor

The preparation of the floor when applying a coating isolation is required to be minimal - it is sufficiently suitable and remove the garbage particles. Wet cleaning is not recommended, it is better to thoroughly spend the floor.
The floor is covered with a primer with a roller until its surface impregnation. If the floor features an increased absorbent ability, it covers two or even three times. Special primers on a polymer basis not only improve the adhesion of mastic, but also create an initial layer of waterproofing.
Corners and joints with walls in obligatory Skinned with a special ribbon with sealing properties. Rubber seals are put on the pipes, the shelves of the floor with them also sample ribbon.

Mastica is bred according to the manufacturer's recommendation. According to the consistency, it looks like warm plasticine. Mastica is comfortably solid roller, and in the knocks and corners - brush. For good waterproofing, the mastic is applied to the walls, at least 20 cm.

Mastics dry about a day. During this time, it is impossible to walk on the floor, as well as allow dust, moisture, foreign objects on it. The dried waterproofing can be coated with a finishing coating with tiles or porcelain stoneware.

Waterproofing of the floor in the bathroom with the help of coating by mastic on a bitumen or cement-polymer basis has a small thickness, while it is durable and reliable. However, it is suitable only for concrete overlaps. If the coatings in the house are wooden, such waterproofing may be insufficient.

In this case, used with two-component compositions on a rubber basis. They consist of directly liquid rubber (liquid rubber) and the activator, which is necessary for its solidification.

Woodwood Waterproofing Technology

Preparation wood floor Under the coating requires some effort and costs - because the rubber composition should not penetrate it, otherwise its consumption will increase dramatically. The draft floor is purified by contaminants, lags are placed on it, a vapor insulation film and insulation slabs. The insulation can be used polystyrene foam, it forms a solid smooth surface. The joints between the plates and lags are sealing a sealant. If mineral mats are used as insulation, on top it is necessary to lay a layer of waterproof plywood.

Mix the liquid rubber with the activator and quickly apply it to the floor with a roller, thoroughly scrubbing the floor stuffs and walls.
It is waiting for the drying of the liquid rubber and assess the quality of waterproofing - it should be smooth and homogeneous. If necessary, apply a second layer.
The finishing coating is produced in the usual way. At the same time it is necessary to take into account that the adhesion is ordinary tiled glue The rubber compositions are usually insufficient, so you need to perform a screed using the reinforcing grid.

This method of waterproofing can be used not only for wooden coatings, but also for concrete. The quality of waterproofing with this method allows it to apply it even in particularly wet rooms, including the pool and the washing compartment of the bath.

When performing floor insulation in the bathroom in any of the above methods, it is important to adhere to the recommendations of the material manufacturer, especially in part of the drying time of the coating. Insufficient exposure of the coating waterproofing can lead to its cracking after the finishing work.

The bathroom is a room in which heightened humidity is constantly marked, warm steam accumulates. Such conditions in the absence of high-quality ventilation lead to the appearance on the walls of condensate. Stressing on a tile, dampness can cause mold fungus in intercutric seams, as well as on furniture. Therefore, during the repair, waterproofing the bathroom under the tile is required. What is better to choose from materials to perform such work in detail in this article.

In addition to spoiled dampness, headset and cladding, there is a risk of moisture penetration into neighboring apartments. Water can leak through microscopic overlap cracks and leave ugly dark divorces on the ceiling. That is why reliable waterproofing under the tile in the bathroom is so important.

Waterproofing on the floor in the bathroom

If desired, this stage of repair is easily carried out on its own.

Preparation for work

This process should be treated with due attention. If you lose sight of something, the proper effect does not work, and during the subsequent operation of the room there may be problems. For laying isolation in rolls, you first need to make a dismantling of an old screed on the floor. It is quite dirty work, take-off time and strength, but without it is impossible without quality repairs.

Dismantling

Thickness concrete screedAs a rule, it is 3-5 cm.

Need to stock required tools: Perforator, concrete column and a corner liquor. After splitting the cement layer, remnants of construction waste, dust remove from the surface. Then you should inspect the base. If on the floor there are irregularities, recesses and cracks, the surface is grinning to a smooth state. After that, the floor can be treated with antifungal mixture and apply primer.

The process of applying primer

For other types of waterproofing, it is also necessary to get rid of screed defects. The working plane must be smooth. The fungicide solution and primer is applied to it. It is important not to forget about the processing of the bottom of the walls. Apply waterproofing at 10-15 cm from the floor. This is necessary as an additional protection against the possible flooding of the room. The floor level in the bathroom is usually lower than in the rest of the rooms. The threshold has a height of about 5 cm. This design allows you to prevent water leak out beyond the bathroom.

Types of materials for waterproofing bathroom

Waterproofing for the bathroom under the tile is carried out using different materials. At the same time, they must all be reliable and waterproof. Harvest and coating solutions are isolated.

Refractory waterproofing is made from bitumen, which is oxidized, and fillers are added to it as a plasticizer, latex, rubber crumb. The composition of such a solution also includes an organic solvent. Nevertheless, when working with such a type of isolation there are some nuances. The composition should be applied to the treated surface at a temperature of 120 degrees Celsius. In the cold, such an insulating coating becomes fragile. Types of insulation on a bitumen-polymer basis are very popular or using rubber.

Equal waterproofing is sold in rolls. Sometimes it has the kind of film with the adhesive basis. At the heart of such materials, as a rule, fiberglass and polyester.

Waterproofing in rolls

The process of laying such an insulation is somewhat easier. The work is to glue the material on the walls and the floor. However, experienced masters recommend using for bathrooms precisely precise insulation materials.

Selection of waterproofing largely depends on the size of the room, its planning, presence or absence in it of different types Sophisticated plumbing devices.

Waterproofing bathroom with various facing types

After leveling and grinding surfaces in the bathroom, you can move to primer work. However, the decoration of the walls and the floor is plasterboard in the bathroom requires very reliable waterproofing so that the glue holds well.

Moisture-resistant plasterboard

To protect the material from humidity, plasterboard must be covered with a special membrane or deceive by mastic.

Even before starting laying sheets of plasterboard, they are covered with moisture-repellent composition. This increases its waterproofing properties several times.

Waterproofing floor in the bathroom under the tile, whose video can be found in our website can be carried out with the help of rolled materials. You need to prepare a cut of the filth of the required size, heat the base of the bitumen, remove the protective layer and paste insulation to the entire surface of the floor. You can use the leveling roller. In this case, each section of the surface is recommended to handle twice or three times.

In the case of applying a coating type of isolation, the mixture is first prepared. It is applied to the surface of the floor and wall with a roller or spatula.

Features of waterproofing in a wooden house

For floors of wood, it is advisable to pay special attention to the processing process by moisture-proof material. A tree is a material that is "afraid of water. If you do not conduct waterproofing, mold will quickly begin to appear in such a bathroom, the walls made of natural wood will deteriorate and with time to deform. The process of rotting the material will begin.

You also need to not forget about careful processing of the ceiling, since warm steam, lifting, will settle on the surface.

For wood, special water-repellent varnish coatings are used. They effectively protect natural material from deformation.

Rules for the choice of waterproofing materials

Specialists prefer one or another type of waterproofing depending on the following factors:

Base. It can be concrete or cement-sandy solution.
Features of the interior of the bathroom. The presence of a shower or a warm floor system in it.

If the bathroom is standard, and the facility of the floor and walls is small, can be selected for insulation inlet material. It contains special synthetic resins. The thickness of such a coating does not exceed 1 mm, so the floor level after flooring does not increase too much.

Waterproof waterproofing

After only 24 hours after the end of the waterproofing work, you can proceed to finishing surfaces.

Some apartment owners prefer to mount the "Warm Paul" system or simply choose a thick tile for cladding. In this case, it is better to use insulation based on cement. The layer of such a coating is thicker. It is 2-4 mm. Such isolation dries longer.

Insulation with liquid rubber

Another name of this material is bitumen mastic. This is a high-quality modern type of flooring of the floor and walls from the harmful effects of moisture.

Liquid Rubber for Waterproofing

Such liquid insulation is made of bitumen and polymers. It is safe and easy to apply. At the same time, work can be done manually using a brush and roller, or to purchase a special hardware that automates the process. Eliminate such advantages of liquid rubber insulation:

elasticity and softness applied layer;
good adhesive properties;
seamless type of insulation;
light application.

In addition to the above advantages of bitumen mastic, it is worth mentioning its property as "undeclocating" to the main coating. Even if the floor is polished impaired, the presence of small flaws and roughness will not affect the quality of isolation.

The technology of conducting liquid waterproofing of the floor in the bathroom includes the following steps:

Surface preparation. It is necessary to thoroughly treat the walls and the floor before applying the mastic. It is necessary to make a screed, alignment of the base. At the same time, do not forget about the requirements for the floor level in the bathroom. As you know, you need to equip the threshold to avoid flooding of all rooms.
At the next stage spend cleaning the treated surfaces and their priming. It should be removed all the litter and dust brush. After that, process the overlappings with a special bitumen-polymer primer. This will provide a better clutch of waterproofing material with the basis. Processed walls and floor leave for several hours to dry.
Then you can proceed to the waterproofing itself. Bituminous mastic covers the floor and walls at the base, measuring the distance at 20 cm. The work can be carried out with a construction brush or spatula.

Waterproofing liquid rubber is widely used in modern construction. It is used to repair in new buildings and for restoration work in old apartments.

The process of waterproofing liquid rubber

The technology of applying such material is simple, does not require special skills. Work is perfectly done by yourself. For coating one square meter The premises will require 3 liters of bitumen mastic.

This is a reliable type of insulation, which protects well in the bathroom from the appearance of mold and leakage of moisture to the next apartment.

Since enhanced requirements are usually put forward to the repair of the bathroom, careful waterproofing is the necessary procedure. It requires some investment of funds, the costs of time and labor, however, in the future it will pay off. You do not have to repair the bathroom again in a year. There will be no problems with exploiting the bathroom.
