Waterproofing a bathroom is an important stage in construction, which cannot be dispensed with. It is difficult to underestimate the impact of moisture on the floor and walls. It happens all the time in a room like this. If the work is not done correctly, then soon any finishing material will become unusable. And the most dangerous thing is the appearance of mold, because it can bring not only an unusable appearance, but also worsen the he alth of all family members.
Do-it-yourself bathroom waterproofing is a simple task. Even a beginner can handle it. It is important to follow the basic rules and instructions, since the slightest oversight leads to the fact that mold occurs. It does not matter what finishing material is planned. Each of them must have prior protection.
Ways
The choice is built depending on what finishing material is used. Because everyone is workingaccording to your scheme and using the right tool. But the most common methods are:
- Waterproofing coating for a bathroom under a tile.
- Plaster.
- Cast.
- Injectable.
- Pasting.
But not every option can be used in the bathroom. Two are best suited - coating and pasting. The choice is built on the basis of what surface is in the room, and also depending on financial capabilities. It is better not to rush and follow each step according to the instructions. Only then can a good result be achieved. Many waterproofing methods become a rough base, after which a topcoat is applied.
Laying waterproofing
Most often, the materials in such works are produced in rolls, and it is not difficult to find them. Contains polymers. Fiberglass and polyester are added for reliability and durability. There are two main options available for sale. This is a welded-on fiberglass fabric that is applied using a special torch and is self-adhesive.
According to statistics, not so often modern people use rolled materials in decoration. This is because there are many nuances and features:
- The base will have to be leveled as much as possible. An error of more than two millimeters is not allowed. And many houses are not built as perfectly as we would like. After leveling, the height of the room changes, which is not suitable for everyone.
- Before applying, you need to completely dry the treatedsurface. It takes more than one hour. Not everyone is comfortable with such conditions.
- The work is done neatly, slowly. It is not easy to achieve the desired result without experience.
Not everyone can observe such features, but if you study the theory beforehand, it will be easier in practice. There are positive aspects of the method. This is the reliability of fixation and the economical use of the material. Once the waterproofing work is completed, work can continue on the surface. These are the main advantages. But everyone decides for himself what is best for waterproofing a bathroom under a tile.
Coated waterproofing
From the name it becomes clear that mixtures should participate in the process. There is a huge range 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 great requirements for the surface being processed.
There is one more feature: the waterproofing material contains 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 maximum protection against the penetration of moisture and condensate. And this is the main task set before the builders. When planning the decoration of the room, you need to understand that not only the floor area, but also part of the wall will be in the work. It is worth doing it qualitatively 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 good. Before starting work, the surface is treated with a primer mixture or other adhesives. A seal is fixed in the corners. As soon as the primer dries, the first layer of protective coating is applied. Using a brush, the composition is rubbed into the surface. It should not exceed two millimeters. Therefore, it is required to carefully and clearly distribute it. After complete drying, a second layer can be applied. This is a tile bathroom waterproofing option.
How long to wait?
Drying time - about 16 hours for the first layer. Do not rush, otherwise you can ruin the protection. Although some believe it can be cut in half by using additional heating. But it is better to wait exactly 16 hours.
Cement compositions
Such materials began 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 in the composition. They fight well with the appearance of microcracks and pits. As a result, the waterproofing of the bathroom is of the highest quality and reliable. But there is an opinion that this is not environmentally friendly.
Mostly cement compositions are filled with polymer dispersions or emulsions. The mixture turns out to be plastic, and it is easy to work with it, creating the most even and protected surfaces from moisture. Masters talk about versatilitycompositions, so they are often used in work not only on the floor, but also on the walls. When bathroom waterproofing is selected for tiles, which is better, it already becomes clear. The selection criterion is reliability.
Inward-Penetrating Protection
These are the compounds that are most often applied to the surface of concrete. The result is maximum protection and durability against moisture. Waterproofing a wooden bathroom occurs due to chemical compounds. They have small particles that are able to fill microcracks in concrete. What follows is an interesting reaction. When contact with moisture begins, the components applied to the floor or walls increase in volume and prevent it from penetrating anywhere.
How to apply such a composition? Everyone will be able to cope with the presented mixtures. The only thing you should not forget about is the order of each action. The work requires a brush (it is better that it be large). The concrete surface must be damp. After applying the first layer, you need to wait until it starts to dry. And only then should the second one be applied. Then for five days you need to keep the treated areas under a waterproof film. After the time has elapsed, you can install the finish coat. Thus, do-it-yourself waterproofing of the walls in the bathroom is performed.
Helpful tips
As in any other finishing work, when waterproofing, surface preparation is first performed. Here is what should happen in the first step:
- If available, remove old trim.
- Appeared garbage is removed to the last detail.
- The surface to be treated is washed thoroughly.
- The resulting unevenness should even out. This can be done with cement mortar.
When chips and cracks appear, they are removed at the preparation stage. This is done regardless of whether the work is on the floor or the wall. If this recommendation is not followed, it will eventually become a serious problem. When the surface dries, a primer mixture is applied. An exception is the work with cement compositions. You can just wet the surface. After that, compounds for waterproofing the bathroom are being prepared.
How to calculate the amount of the mixture and prepare it?
Construction is not only a complex, but also a costly process. In order not to overpay extra money during repairs, it is worthwhile to pre-calculate, depending on the surface to be treated. This will prevent the reverse reaction when the mixture is small and the area for work is large. Most often, the packages have 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 there is no need to breed. This does not mean that there is no need to count. After all, why buy too much, throwing money away? When working with cement compositions, you will need to have the right container into 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, becausemanually 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 needed to waterproof the bathroom under the tiles? The surface area included in the work is taken and divided by 1.5. The result will be a figure showing the material consumption per square meter of the room. Those who have already worked with such materials, when waterproofing a bathroom in a house, recommend rounding the resulting figure up. A small margin is always required, especially for people working without experience in this area.
Squad distribution
To apply a waterproofing compound to the surface of the floor or walls, you can use the following tool:
- Roller.
- Brush.
- Spatula.
With the help of it, the mixture is applied in several layers. In order to avoid problems in the process of 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 not apply the composition haphazardly. 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 of application, but also recommendations for applying the mixture (namely: how thick is the layer, how many should be, etc.). These data must not be overlooked. Otherwise, it may not turn out the way you would like. Before starting workthe 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 additional sealant and strengthen with construction tape.
When plumbing is installed, you need to protect the seams and joints. On sale there are different compositions that save not only from condensate, but also from mold. This stage must not be skipped so that there are no misunderstandings during the operation of the premises. Builders believe that today there are enough mixtures that will easily create maximum protection and prevent condensation.
Conclusion
So we figured out how to properly waterproof your bathroom. As you can see, this work can be done by hand. Summing up, it should be noted that any room with high humidity should be treated with mixtures with protective functions. Before starting the operation, it is worth knowing the pros and cons of any composition. The method of work has its own nuances. Do not ignore the information on the label from the manufacturer. Most often now use universal mixtures.
