Waterproofing the floor in the bathroom under the tile with your own hands

When carrying out construction and repair work, it is necessary to take into account certain features of the premises. For example, in the bathroom you need a waterproofing floor. A lot depends on the quality of the procedure. First of all, there is a chance to avoid certain problems with neighbors if water has suddenly leaked. In addition, waterproofing allows you to protect the floor from the negative effects of moisture. Also, the additional coating makes it possible to extend the life of many finishing materials.

Why do I need a waterproofing floor in the bathroom under the tile?

Many believe that equipping the waterproofing in the bathroom is a waste of money. However, this is not the case. First of all, waterproofing allows you to protect the premises, 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 on its own, then it will take considerably 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 and with the arrangement of some heating systems. This procedure is also 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, Ceresite, Aqua Stop, Hercules and so on are liquid solutions that are used for pouring 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 on a wooden covering or a concrete screed. There are coating compositions. Under this category are suitable rubberized materials, varnishes and bituminous mastics.

Of course, the method of laying the waterproofing depends on the chosen composition. For example, roll materials are better to use when carrying out non-repair, and construction work. In such cases, it is recommended to use an insulator on the roof, in rough floors and basements.

If fine repair works are carried out, it is better to use compositions for coating, for example, bituminous mastics, special solutions and so on.

Preparatory work

Before you begin to lay the waterproofing layer, you must carefully prepare the surface. If the floor is concrete, then to begin with it is necessary to fill an equal screed, the thickness of which should not exceed 2 centimeters. The surface must be free of dust. It can be cleaned with a conventional vacuum cleaner. Of course, it is not worth using expensive equipment, as the filters will very quickly become unusable. Also on the screed there should be no cracks. If they did appear, then they should be slightly expanded and filled with a solution.

In order for the waterproof layer to bond well to the coating, it is necessary to treat the surface with a primer. The composition must dry out. Primers should be bought special, which is designed for processing concrete floors.

If the floor in the house is wooden, then it is necessary to secure the boards securely. It is also possible to cover it completely with a sheet of plywood.

Which composition should I choose

So, how and what is the waterproofing of the floor in the bathroom tiled? Ceresit and other popular brands are sold in almost any construction shop. The assortment of such goods is quite large. Therefore, the question arises: what to buy? It should be remembered that similar compounds are the same type and work on one and there principle. The main difference is in some properties of materials, in the consumption and methods of application.

If desired, you can buy immediately ready liquid formulation or a dry mixture, which before work will have to be planted independently in accordance with the recommendations of manufacturers. In any case, if all the rules are met, a qualitative waterproofing of the floor in the bathroom under the tile in a wooden house and in a residential apartment is obtained.

Preparation of the solution

When the primer, applied to the rough floor, dries and absorbs, you can proceed to the main stage - the creation of a protective layer. Waterproofing the floor in the bathroom under the tile with your own hands is carried out with the help of additional tools. Do not neglect the preparatory work and coating of special compounds. The cost of the primer is relatively low, and it can be applied independently. This will achieve high quality of the work performed.

To make a waterproofing, you need to prepare a solution. If you have purchased a special liquid formulation for a wooden floor, then you can skip this step. If the choice fell on a dry mixture, then you will have to prepare the solution yourself. For this you need:

1. In a deep container, pour in a dry mixture and add water. At the same time, certain proportions must be observed: one part of the formulation requires one part of the liquid.
2. The mixture should be thoroughly mixed so that a homogeneous mass without bubbles of air and lumps is obtained. To do this, you should use a drill, as well as a special nozzle, which is designed specifically for mixing solutions.

What's Next

After the solution is ready, it is possible to proceed with the installation of the floor waterproofing 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 responsible 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 the corners, as well as the joints, should be given special attention. It is better to cover them several times with a waterproofing compound.

How to apply correctly

Waterproofing the floor in the bathroom under the tile is an important stage in the repair work. It is necessary to do everything qualitatively and correctly. Apply waterproofing composition is better in several layers: first applied first, and second - after 6 hours. After that, any building and maintenance work in the building should be stopped for about 48 hours. This is necessary so that the mixture applied to the floor can dry out 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. This is not very expensive, so the solution should be applied carefully and without regret. If a liquid waterproofing of the wooden floor in the bathroom is applied under the tile, it is possible to coat the surface in several layers with a brush. In some cases, the treatment of walls to a height of 40 centimeters.

If desired, you can use a backfill waterproofing. However, it should be noted that such formulations do not provide the necessary protection of the surface from the effects of 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 a molded floor waterproofing in the bathroom under the tile. The instruction for using such a tool is understandable and does not raise questions. This material has excellent properties due to the application technology. However, it is very difficult to independently carry out work on the arrangement of such waterproofing. To avoid a large number of errors it is better to invite specialists.

Painting method

Painting method of arranging the floor waterproofing in the bathroom under the tile is considered to be the simplest. If necessary, the work can be done 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 layer of waterproofing dries, you can make a small screed that will allow to level the surface, strengthen it, and also prepare it for further laying the tile or other coating.
