The waterproofing of the bathroom is an important stage in construction, which cannot be dispensed with. It is difficult to underestimate the effects of moisture on floors and walls. In such a room, this always happens. If the work is done incorrectly, then soon any finishing material will become worthless. And the most dangerous is the appearance of mold, because it can bring not only an unsuitable appearance, but also worsen the health of all family members.
The process of waterproofing a bathroom with your own hands is a simple task. Even a novice can handle it. It is important to observe elementary rules and instructions, since the slightest oversight leads to the occurrence of mold. It does not matter what kind of finishing material is planned. Each of them must have preliminary protection.
Ways
The choice is made depending on what finishing material is used. Because work with each is carried out according to its own scheme and using the right tool. But most often the following methods are found:
- Tile waterproofing for the bathroom under the tile.
- Plastering.
- Cast.
- Injection
- Okay.
But not every option can be used in the bathroom. Two of them are best suited - coating and pasting. The choice is built on the basis of which surface in the room, as well as depending on financial capabilities. It is better not to rush and perform each step according to the instructions. Only then can a good result be achieved. Many waterproofing methods become a rough basis, after which a topcoat is applied.
Waterproofing waterproofing
Most often, the materials in such works are produced in rolls, and it is not difficult to find them. The composition includes polymers. For reliability and durability fiberglass and polyester are added. There are two main options for sale. This is a built-up fiberglass, which is superimposed when using a special burner and self-adhesive.
According to statistics, not so often modern people began to use rolled materials in the decoration. This is due to the fact that there are many nuances and features:
- The base will have to be aligned as much as possible. An error of more than two millimeters is not permitted. And many houses are not built as perfectly as we would like. After alignment, the height of the room changes, which is not suitable for everyone.
- Before applying, you need to completely dry the treated surface. It takes more than one hour. Not everyone is comfortable with such conditions.
- Work is carried out carefully, without rushing. To achieve the desired result without experience is not easy.
Not everyone can observe such features, but if you study the theory in advance, in practice it will be easier. There are positive aspects to the method. This is a reliable fixation and economical use of the material. Once the waterproofing work is completed, you can continue to work on the surface. These are the main advantages. But everyone decides for himself what is best for waterproofing a bathroom under a tile.
Coating waterproofing
From the name it becomes clear that mixtures should be involved in the process. There is a huge assortment on the market, and you need to choose the right option. It is better to make a choice depending on the available surface in the bathroom. Although the masters say that there are no large requirements for the surface to be treated.
There is another feature: as part of the waterproofing material there is bitumen, but it is not environmentally friendly. In addition, it is not so easy to work with the mixture, but the result will please everyone, since the protection is maximum from the penetration of moisture and condensate. And this is the main task assigned to the builders. When planning the decoration of the premises, it must be understood that not only the floor area, but also part of the wall will be in the work. It is worth doing it efficiently and responsibly.
Liquid membranes
This substance can be laid on the floor and walls. But it is better to pre-level the surface. Then the protection is high-quality. Before starting work, the surface is treated with a primer mixture or other adhesive compounds. A seal is fixed in the corners. As soon as the primer dries, a first coat of protective coating is applied. Using a brush, the composition is rubbed into the surface. It should not exceed two millimeters. Therefore, you need to carefully and clearly distribute it. After complete drying, a second coat can be applied. This is a variant of waterproofing a bathroom under a tile.
How much to wait?
Drying time is about 16 hours for the first layer. Do not rush, otherwise you can spoil the defense. Although some believe it can be halved using additional heating. But it is better to wait for exactly the 16-hour period of time.
Cementitious compounds
Such materials have begun to gain popularity recently in the market. The main advantage is that adhesion to any surface is easy and durable. The hydrophobicity index is achieved due to the presence of polymers. They fight well with the appearance of microcracks and pits. As a result, the waterproofing of the bathroom is obtained as high quality and reliable. But there is an opinion that this is not environmentally friendly.
Basically, cement compositions are filled with polymer dispersions or emulsions. The mixture is plastic, and it is easy to work with it, creating the most even and protected surfaces from moisture. Masters talk about the versatility of compositions, so they often use them in work not only on the floor, but also on the walls. When the bathroom waterproofing is selected under the tile, which is better, it already becomes clear. The selection criterion is reliability.
Penetration protection
These are compounds that are most often applied to a concrete surface. As a result, maximum protection and durability against moisture are achieved. The waterproofing of the wooden bathroom is due to chemical compounds. They have small particles that can fill microcracks in concrete. Then an interesting reaction takes place. When contact with moisture begins, the components deposited on the floor or walls increase in volume and prevent it from penetrating anywhere.
How to apply such a composition? Everyone will manage to cope with the presented mixtures. The only thing you should not forget is the sequence of each action. A brush is required in the work (it is better that it be large). The concrete surface must be moist. After applying the first coat, you need to wait until it begins to dry. And only then should the second be applied. Then for five days you need to keep the treated areas under a waterproof film. After time, you can install the finish coating. Thus, do-it-yourself waterproofing the walls in the bathroom.
Useful Tips
As with any other finishing work, when waterproofing, surface preparation is first performed. Here is what should happen in the first step:
- If available, the old finish is removed.
- Appeared garbage is cleaned to the last detail.
- The treated surface is thoroughly washed.
- The resulting unevenness should be aligned. This can be done with cement mortar.
When chips and cracks appear, they are removed at the preparation stage. This is done regardless of what the work is going on with - floor or wall. Failure to comply with this recommendation will ultimately become a serious problem. When the surface dries, a primer mixture is applied. An exception is the work with cement compounds. You can only wet the surface. After this, compositions for waterproofing the bathroom are prepared.
How to calculate the amount of the mixture and cook it?
Construction is not only a complex, but also a costly process. In order not to overpay the extra money during the repair, it is worthwhile to make preliminary calculations, depending on the surface being treated. This will prevent a reverse reaction when the mixture is small and the area for work is large. Most often on the packages there is additional information from the manufacturer. In order not to make a mistake, you need to focus on this.
Although today there are enough ready-made mixtures on sale, and no need to breed. This does not mean that you do not have to count. After all, why get too much by throwing money away? When working with cement compositions, you will need to have the right capacity in which water is poured. Then, in accordance with the instructions, the composition is poured. To mix the components well, it is worth using construction mixers, because manually achieving a homogeneous mass is not always easy. After the mass stands for ten minutes and mixes again.
But how to calculate how much mixture is required for waterproofing a bathroom under a tile? The surface area included in the work is taken and divided by 1.5. The result will be a figure showing the consumption of material per square meter of space. Those who have already worked with such materials, waterproofing the bathroom in the house, recommend that the resulting figure be rounded up. A small supply is always required, especially for people working without experience in this field.
Composition distribution
To apply a waterproofing composition to the surface of a floor or walls, you can use the following tool:
- Roller.
- Brush.
- Putty knife.
Using it, a mixture is applied in several layers. In order to avoid problems during the work, you need to create a suitable microclimate. So, the temperature should be about +15 degrees, and humidity - no higher than sixty percent. You can’t put the composition on hit. It is necessary to make the surface smooth and even. The application of the second and subsequent layers should be done perpendicular to the first. This is done only after the previous one has completely dried.
Each manufacturer on the package gives not only the rules for use, but also recommendations for applying the mixture (namely: how thick the layer is, how many there should be, etc.). This data should not be overlooked. Otherwise, it may not work out as we would like. Before starting work, the question often arises: what to do with the main places of leaks, joints of different surfaces? There is an answer. Before starting work, you need to go through these places with an additional sealant and strengthen with a construction tape.
When plumbing is installed, then you need to protect the seams and joints. On sale there are various compounds that save not only from condensate, but also from mold. This stage should not be skipped so as not to result in misunderstandings during the operation of the premises. Builders believe that today there are enough mixtures that without problems will create maximum protection and prevent condensation.
Conclusion
So, we figured out how to properly waterproof the bathroom. As you can see, this work can be done with your own hands. Summing up, it should be noted that any room with high humidity should be treated with mixtures with protective functions. Before the operation, it is worth learning the pros and cons of any composition. The working method has its own nuances. Do not ignore the information on the label from the manufacturer. Most often they use universal mixtures.
