Waterproofing the bathroom under the tile - what is better? Waterproofing device, material selection

The bathroom in the apartment (or house) is that room, which is characterized by a rather specific operational regime. The condensate, due to temperature fluctuations, splashes, accidentally spilled water - all these factors constantly and systematically test the lining of walls and floor for strength, penetrate into the technological seams.

Water, accumulating in the places of docking of structures under the tile, in the zones of connection and passage of pipes, creates the most comfortable conditions for the residence and reproduction of whole colonies of fungi and bacteria. The long-term effects of these "tenants" are the damaged walls and ceilings of the premises, poisoning the hosts with toxins. In order to avoid all these horrors, and required mandatory waterproofing of the bathroom under the tile. What is best for these purposes? It's worth thinking about.

The most popular materials

Water has a destructive power. And, probably, how much humanity exists, as much as it is opposed to the water element. By now, there are a variety of waterproofing materials. The types of consumers most demanded are given below:

- plates, panels for creating a water-repellent cladding layer;

- flexible materials that can be welded or glued;

- Painting materials and paste-like mixtures for coating (the walls and the floor treated in this way are covered with a layer of waterproofing up to 1.5 cm thick);

- sprayed formulations form foam-cement or foam plastic barriers for water;

- special plaster waterproofing, and at the same time and leveling vertical surfaces;

- materials saturated with hydrophobic components and reinforcing fiber;

- impregnations and injections, capable of changing the structure of porous building materials (a consequence - strengthening moisture-proof properties and strength).

Criterias of choice

Depending on the technical characteristics of the room in which the work will be done, choose the type of one, and preferably two perfectly working in tandem materials. It happens quite difficult (especially not for a specialist) to decide on the options that optimally solve the task of waterproofing the bathroom. However, one must keep in mind the following:

- moisture protection of sanitary facilities in the house does not require the same powerful waterproofing as the foundation of the structure;

- One should bear in mind that in the event that the waterproofing of the bathtub is made by oneself, the technology should not be too complicated;

- The price of the issue also matters, since consumables can be very expensive.

Comparing all these factors, as a rule, it can be concluded that the most acceptable for waterproofing the bathroom and bathroom will be a coating and pasting. To perform these types of work today, a lot of different materials and finished products are produced, differing in composition, price and technology.

Definition of work front

There are a lot of options for carrying out waterproof work in sanitary rooms. They are no less than the materials known and available today, with the help of which waterproofing of the bathroom under the tile is carried out. Which is better, what should I prefer?

There are three fundamental factors determining the work areas and the area of the forthcoming processing. In the bathroom from the damaging effects of water can be protected:

- only a horizontal surface (floor), necessarily forming small side walls (≈ 10 cm) along the walls;

- floor and areas around the sanitary equipment (bath, shower, washbasins, etc.);

- floor and walls completely, with the processing of the partitions along the entire height.

The need to pre-give preference to some kind of waterproofing is related to the way in which a water-repellent barrier will be created. The same material can be applied completely differently on the surface horizontally vertically.

Waterproofing by coating

This type of waterproofing is a single or multi-layer coating with a thickness of 1 mm to several centimeters, which is created by applying a plastic compound on the surface protected from moisture.

If the bath is waterproofed, the following types of materials are used:

- Paint, which create a thin protective film on the surface: diluted to liquid bitumen, the same kind of mastic, water repellent compounds for processing wood and metal structures (varnishes, paints). On vertical surfaces such materials are applied in two layers with a brush or roller. On the floor, the composition is simply poured out and evenly distributed with a squeegee-squeegee.

- Bituminous mastics, paste-like compounds are the same on the basis of oxidized bitumen with the addition of modifying additives, minimizing toxicity and increasing elasticity and strength characteristics.

The coating waterproofing, which creates a continuous seamless surface on the surface to be treated, should be preferred in those cases when the bathroom needs to fill the screed.

Basic principles of the coating

First you need to remove all construction debris and clean the surface of old, previously applied coatings, varnishes, paints and oils, repair all existing damage. Further, it is necessary to extend at least 2 cm all the joints of plates, panels, lines of interface of walls and ceilings. Finished longitudinal shtroby degreased, and they put a self-adhesive waterproofing cord (floating floor in the bathroom is also processed). Further, according to the instructions of the instruction, a special sealing tape is glued over the cord . The next stage is actually the coating of the surfaces planned for processing. The process ends with plastering for the purpose of leveling and pouring the screed.

Waterproofing cord is permissible to replace silicone mass, packed in tubes. The process of filling silicones with silicone should go continuously, the excess formed is cut with a spatula.

Waterproofing by gluing

Oak waterproofing can be called any waterproof coating, mounted from several layers of special materials (film, sheets, rolls) with the use of special glue compositions. Laying of any waterproofing materials overlap is a prerequisite for obtaining a quality waterproofing of the bathroom under the tile.

What is better to prefer as a gluing factor? Often use the good old way of heating the edges of the materials to be glued together with a gas burner. However, this is not too safe.

On the contrary, the modern market is saturated with different types of glue compounds. There are even those that do not require heating before use. One of the newest is the polyurethane mastic "Unihex-2". The entire cooking technology consists of mixing the two components and - the glue is ready for use. Using a spatula, it is applied to the edge of the sheet, and the next coating sheet is overlapped. This adhesive also has the properties of a sealant.

Pros and cons of sticking

Before you make waterproofing in the bathroom by gluing, you need to evaluate the positive and negative aspects of this process. Of course, the attractive side is the budget price. Of the negative points, it is worthwhile to pay attention to the fact that it is necessary to carry out preliminary measurements and then to cut the material.

Further, the protected surface should not have large differences in height - permissible 2 mm per 2 meters of length. For the melted version, the use of a burner will be required, and the work will be quite complex, since the bathrooms mostly occupy a small area. In addition to all the above, it should be noted that the flooring of the material webs and the thorough alignment of the corners are rather laborious processes. Not having the proper skills, the waterproofing material can be overheated by the burner or tear when forming the corner.

Technology of work

What works need to be done before the waterproofing of the bathroom under the tile? Is it better to do everything yourself or to invite a master? Naturally, if you have the skills, it will be cheaper to do everything yourself.

Preliminarily, the surfaces are leveled and the complete drying of the screed and plaster is awaited. Next, remove all debris (dust, mote, etc.) and double cover the surface with soil. Then, all butt seams are waterproofed and, if necessary, applied mastic or polymer glue. Cut out the materials according to the preliminary measurements and allow them to lie for at least 24 hours.

Then you can start the process of gluing. The first sheet is glued as convenient for the master. From what place will start the work, does not matter. The edges of each next sheet are coated with glue and overlap (no more than 20 cm) on the previous sheet. After the end of the first layer, the sides are formed to protect the zones of the bathroom, shower, sink, etc. Waterproofing on the walls is glued from the bottom up. The strips of the second layer of waterproofing are glued across the previous one.

Waterproofing of sanitary facilities in a wooden house

Waterproofing the bathroom in a wooden house has its own specific features. A tree with water "is not friendly", and if properly not to take care of the waterproofing, the mold will quickly appear in the bathroom, the wooden interior details will be deformed and quickly become worthless.

Since the floors of the dwelling are made of wood, it is important to pay attention to their treatment with waterproofing agents. Also it is necessary to remember the careful processing of the ceiling, on which, when condensed, the warm vapor settles in the form of drops of water.

For waterproofing works in wooden houses, special water-repellent lacquer coatings are most often used, which effectively protect natural wood from deformation.

Price range

With regard to investment, it is certainly more profitable to purchase and use during repair, coating waterproofing materials, the price of which is much lower than for oklechnye. For example, a package of 15 kg of bitumen insulation mastic will cost the consumer 240-250 rubles. If we bear in mind that for the installation of a waterproofing layer 2 mm thick, 3.2 kg of material per sq. M. Surface, it becomes clear that this method is very, very economical. And if you take into account that the work can be done independently, good, no special skills are required and the specialist can not be invited (and not to pay extra money), then from the point of view of financial investments this method of waterproofing looks more than attractive.

You can buy mastic with improved characteristics, which include the materials of the company "Technonikol". Packing in 20 kg will cost the consumer in 1200 - 1300 rubles. Such a cost will also not lead to a financial crisis in every single family, and the bathroom will be reliably protected from leaks and floods.

Is there an alternative?

The classic version of the tiled floor in the bathroom is a thing of the past. Today, modern coatings such as bulk or 3D floors, anti-slip coatings "Stone carpet" are increasingly in demand.

All these floors in themselves represent ideal waterproofing materials, the properties (water-repellent) of which are ensured by their monolithic structure and strength. However, the arrangement of such coatings will require quite serious financial investments. If any, everything is fine - you can create an ultramodern design in the bathroom. Otherwise, the old kind tile on the floor and walls will create an atmosphere of coziness and comfort.
