A bathroom is a room in which there is constantly increased humidity, warm steam accumulates. Such conditions in the absence of high-quality ventilation lead to the appearance of condensate on the walls. Stagnation on tiles, dampness can cause mold in the tile joints, as well as on furniture. Therefore, during the repair, it is necessary to waterproof the bathroom under the tiles. What is better to choose from the materials for performing such work, we will consider in detail in this article.
In addition to the headset and cladding spoiled by dampness, there is a risk of moisture penetrating into neighboring apartments. Water can seep through microscopic cracks in floors and leave unsightly dark stains on the ceiling. That is why reliable waterproofing under tiles in the bathroom is so important.
Waterproofing on the floor in the bathroom
If desired, this stage of repair is easily done on your own.
Preparation for work
This process should be treated with due care. If something is overlooked, the desired effect will not work, and problems may arise during the subsequent operation of the premises. To lay insulation in rolls, you first need to dismantle the old screed on the floor. This is a rather dirty job that takes time and effort, but without it, high-quality repairs are impossible.
Priming process
For other types of waterproofing, it is also necessary to get rid of screed defects. The work surface must be level. A fungicidal solution and a primer are applied to it. In this case, it is important not to forget about the processing of the lower part of the walls. Apply waterproofing at a level of 10-15 cm from the floor. This is necessary as an additional protection against possible flooding of the premises. The floor level in the bathroom is usually lower than in other rooms. The threshold has a height of about 5 cm. This design prevents water from flowing outside the bathroom.
Types of materials for waterproofing a bathroom
Waterproofing for a bathroom under a tile is carried out using different materials. Moreover, they must all be reliable and waterproof. Allocate pasting and coating solutions.
Coating waterproofing is made from bitumen, which is oxidized, and fillers are added to it in the form of a plasticizer, latex, rubber crumb. The composition of such a solution also includes an organic solvent. However, there are some nuances when working with this type of insulation. The composition must be applied to the surface to be treated at a temperature of 120 degrees Celsius. In the cold, such an insulating coating becomes brittle. Types of insulation based on bitumen-polymer or with the use of rubber are very popular.
Pasting waterproofing is sold in rolls. Sometimes it looks like a film with an adhesive base. The basis of such materials, as a rule, is fiberglass and polyester.
Waterproofing in rolls
The process of laying such insulation is somewhat easier. The work consists in gluing the material on the walls and floor. However, experienced craftsmen recommend using coating insulating materials for bathrooms.
The choice of waterproofing largely depends on the size of the room, its layout, the presence or absence of various types of complex plumbing fixtures in it.
Carrying out waterproofing of the bathroom with various types of cladding
After leveling and grinding the surfaces in the bathroom, you can proceed to the priming work. However, finishing the walls and floors with drywall in the bathroom requires a very reliable waterproofing so that the adhesive adheres well.

Features of waterproofing in a wooden house
For wooden floors, it is advisable to pay special attention to the processing of moisture-proof material. Wood is a material that is "afraid" of water. If waterproofing is not carried out, mold will quickly begin to appear in such a bathroom, natural wood walls will deteriorate and deform over time. The process of decay of the material will begin.
It is also necessary not to forget about the careful processing of the ceiling, since warm steam, rising, will settle on the surface.
For wood, special water-repellent varnish coatings are used. They effectively protect the natural material from deformation.
Rules for the selection of waterproofing materials
Experts prefer one or another type of waterproofing, depending on the following factors:
- Base. It can be concrete or made of cement-sand mortar.
- Bathroom interior features. The presence of a shower or floor heating system in it.
If the bathroom is standard, and the area of \u200b\u200btiling the floor and walls is small, you can choose gluing material for insulation. It contains special synthetic resins. The thickness of such a coating does not exceed 1 mm, so the level of the floor after the flooring will not increase too much.
Gluing waterproofing
After only 24 hours after the completion of waterproofing work, you can proceed to surface finishing.
Some apartment owners prefer to install a "warm floor" system or simply choose a thick tile for cladding. In this case, it is better to use cement-based insulation. The layer of such a coating is thicker. It is 2-4 mm. Such insulation dries longer.
Insulation with liquid rubber
Another name for this material is bituminous mastic. This is a high-quality modern type of floor and wall surface protection 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. In this case, the work can be carried out manually, using a brush and roller, or you can purchase special equipment for this, which automates the process. There are such advantages of liquid rubber insulation:
- elasticity and softness applied layer;
- good adhesive properties;
- seamless insulation type;
- easy application.
In addition to the above advantages of bitumen mastic, it is worth mentioning such a property as “undemanding” to the main coating. Even if the floor is not perfectly sanded, the presence of small flaws and roughness will not affect the quality of the insulation.
The technology for conducting liquid waterproofing of the floor in the bathroom includes the following steps:
- Surface preparation. It is necessary to carefully process the walls and floor before applying the mastic. It is necessary to make a screed, leveling the base. At the same time, do not forget about the requirements for the level of the floor in the bathroom. As you know, it is necessary to equip the threshold in order to avoid flooding of all rooms.
- At the next stage, carry out cleaning of treated surfaces and their priming. Remove all debris and dust with a brush. After that, treat the floors with a special bitumen-polymer primer. This will ensure better adhesion of the waterproofing material to the base. The primed walls and floor are left for several hours to dry.
- Then you can proceed with the waterproofing itself. The floor and walls at the base are covered with bituminous mastic, measuring a distance of 20 cm from below. Work can be done with a construction brush or spatula.
Waterproofing with liquid rubber is widely used in modern construction. It is used for repairs in new buildings and for restoration work in old apartments.
Liquid rubber waterproofing process
The technology of applying such material is simple, does not require special skills. The work is quite capable of doing on their own. To cover one square meter of the room, 3 liters of bituminous mastic will be required.
This is a reliable type of insulation that well protects the tiled finish in the bathroom from mold and moisture seepage into the neighboring apartment.
Since bathroom renovations are usually more demanding, thorough waterproofing is a must. It requires some investment of funds, time and labor, however, in the future it will all pay off. You won't have to renovate your bathroom again in a year. There will be no problems with the operation of the bathroom.
