When carrying out construction and repair work, some features of the premises should be taken into account. For example, the bathroom needs waterproofing the floor. A lot depends on the quality of such a procedure. First of all, there is a chance to avoid certain problems with neighbors if water suddenly leaks. In addition, waterproofing protects the floor from the negative effects of moisture. Also, an additional coating makes it possible to extend the life of many finishing materials.
Why do I need waterproofing the floor in the bathroom under the tile?
Many believe that arranging waterproofing in the bathroom is a waste of money. However, this is not the case. First of all, waterproofing allows you to protect the room, as well as neighboring apartments from flooding.
The cost of arranging an additional layer costs, as a rule, 400-800 rubles per square meter. If all the work is done independently, it will take much less. The cost of waterproofing depends on the price of building materials, which, in turn, depends on the composition, as well as the types of application of solutions.
Also, waterproofing the floor in the bathroom under the tile is required when arranging some heating systems. A similar procedure is necessary in cases where the house is built of foam blocks. This building material should be protected from moisture.
Types of materials
At the moment, there are several main types of materials that are designed to equip an additional protective layer. What should be the waterproofing of the floor in the bathroom under the tile? “Knauf”, “Ceresit”, “Aqua stop”, “Hercules” and so on - these are liquid solutions that are used to fill floors. They are sold, as a rule, in the form of a loose mixture. In addition, there are roll materials that are fused or glued to a wooden coating or concrete screed. There are coating compounds. Rubberized materials, varnishes and bituminous mastics are suitable for this category.
Of course, the method of laying waterproofing depends on the selected composition. For example, rolled materials are best used when carrying out construction, not repair. In such cases, it is recommended to use an insulator on the roof, in rough floors and basements.
If finishing repairs are carried out, it is better to use compounds for coating, for example, bituminous mastics, special solutions and so on.
Preparatory work
Before you start laying the waterproofing layer, you must carefully prepare the surface. If the floor is concrete, then for a start it is worth pouring an even screed, the thickness of which should not exceed 2 centimeters. In this case, the surface must be free of dust. It can be removed using a conventional vacuum cleaner. Of course, you should not use expensive equipment, since the filters will become unusable very quickly. There should also be no cracks in the screed. If they nevertheless appeared, then they should be expanded a little and filled with a solution.
In order for the waterproofing layer to adhere well to the coating, it is necessary to treat the surface with a primer. The composition must be dry. The primer should be bought special, which is designed for the treatment of concrete floors.
If the floor in the house is wooden, then it is necessary to securely fasten the boards. You can also cover it completely with a sheet of plywood.
Which composition to choose
So, how and with what is the waterproofing of the floor in the bathroom under the tile arranged? Ceresit and other popular brands are sold in almost any hardware store. The assortment of such products is quite large. Therefore, the question arises: what to get? It should be remembered that such formulations are of the same type and work on the same principle. The main difference lies in some properties of materials, in consumption and application methods.
If desired, you can purchase immediately ready-made liquid composition or a dry mixture, which before work will have to be diluted independently in accordance with the recommendations of the manufacturers. In any case, subject to all the rules, high-quality waterproofing of the floor in the bathroom is obtained under the tiles in a wooden house and in a residential apartment.
Solution preparation
When the primer, applied to the subfloor, dries and soaks, you can proceed to the main stage - the creation of a protective layer. Do-it-yourself waterproofing the bathroom floor with tiles using additional tools. Do not neglect the preparatory work and the application of special formulations to the coating. The cost of the primer is relatively low, and you can apply it yourself. This will achieve high quality work.
To make a waterproofing, it is necessary to prepare a solution. If you purchased a special liquid composition designed for a wooden floor, you can skip this step. If the choice fell on the dry mixture, you will have to prepare the solution yourself. To do this, you need:
- Pour the dry mixture into a deep container and add water. In this case, certain proportions should be observed: one part of the composition requires one part of the liquid.
- The mixture should be thoroughly mixed so that a homogeneous mass is obtained without air bubbles and lumps. To do this, use a drill, as well as a special nozzle, which is designed specifically for mixing solutions.
What's next
After the solution is ready, you can begin to arrange the waterproofing of the floor in the bathroom under the tile. To apply the solution, you can use a special roller, brush or spatula. In this case, the choice depends not only on the ease of application, but also on the area of ​​the room. Do not forget about such important places as the joints between the wall and the floor. Here, experts recommend laying a special waterproofing tape. If you decide to do without this material, then you need to pay special attention to the corners, as well as the joints. It is better to coat them several times with a waterproofing compound.
How to apply
Waterproofing the floor in the bathroom under the tile is an important stage in the repair work. Everything must be done qualitatively and correctly. It is better to apply a waterproofing composition in several layers: first, the first is applied, and the second - after 6 hours. After that, any construction and repair work in the room must be stopped for about 48 hours. This is necessary so that the mixture applied to the floor can dry better. It is worth noting that the quality of waterproofing is very important for some types of heating systems.
The average cost of the mixture is about 500 rubles. It is not very expensive, so the solution should be applied carefully and not stinging. If liquid waterproofing of the wooden floor in the bathroom is used under the tile, then you can cover it with a surface in several layers with a brush. In some cases, processing walls to a height of 40 centimeters is required.
If desired, you can use the backfill waterproofing. However, it should be noted that such compositions do not provide the necessary protection of the surface from moisture. When carrying out such work, a sufficiently large layer of backfill material should be made. This is the only way to avoid many problems in the future.
In addition, there is injection molded waterproofing of the floor in the bathroom under the tile. Instructions for using such a tool are understandable and do not raise questions. Such material is characterized by excellent properties due to the application technology. However, it is very difficult to independently carry out such waterproofing. To avoid a large number of errors, it is better to invite specialists.
Painting method
The painting method of arranging the waterproofing of the floor in the bathroom under the tile is considered the simplest. If necessary, the work can be carried out easily, quickly and at no particular cost. However, it should be borne in mind that such a protective coating has a short service life. This indicator is no more than 5 years.
After the waterproofing layer has dried, you can make a small screed that will allow you to level the surface, strengthen, and also prepare it for further laying of tiles or other coatings.
