The waterproofing of the bathroom is an important aspect during repair, which can save neighbors from below from unpleasant consequences in the event of a flood. Thanks to waterproofing, the water will not be able to penetrate through dense material and it will turn out to be quickly assembled. This will avoid expensive repairs in one or more apartments from below.

In addition, waterproofing prevents the reproduction of fungi and mold, since moisture is not absorbed into concrete under the floor. This provides a healthy and comfortable atmosphere in the bathroom.
There are 2 types of waterproofing: coating and rolling.
Crystaline is cement, polymer and bitumen mastic. It is applied to the base of the floor with a spatula, brush, brushes or roller.
Rolled waterproofing is ready -made rolls that are laid on the base of the floor. Such waterproofing can be performed on the basis of bitumen, PVC film or roofing material.
Method of installation of coating waterproofing in 2 layers
As waterproofing, you can use the material on the cement basis of Mapelastic. This is a fairly elastic coating that is convenient to apply. One waterproofing kit is enough for about 1 surface layer of 10 m2.
You will also need an insulation tape. For example, Weber.Tec 828 DB 75.
To work with coating waterproofing, you will need a roller, brush, spatula and mixer to knead the solution.
Play preparation for waterproofing
The base of the floor should be cleaned of dust and applied to it a primer. If the apartment is not new and waterproofing has already been made there earlier, then the old layer should be cleaned of mold and peeling particles. Then everything needs to be washed with water. After the floor is dry, waterproofing can be applied.
Waterproofing should not be done if the room has less than +5 ° C. The surface must be dried from moisture.
Waterproofing. The first layer
Crystal waterproofing consists of two components: a liquid solution in a canister and a dry mixture in a bag. First, a liquid component is poured into the container, and then a dry mixture is added. The finished mixture should have a liquid homogeneous consistency.
First, waterproofing at the inner corners of the bathroom at the junction of the floor and walls should be applied. On top you need to lay the insulating tape and press it into the waterproofing, having expelled excess material from under the tape.
Waterproofing is applied to the floor of the floor without spaces. This can be done with a brush, roller or gear spatula. It is also worth applying waterproofing to a height of 30 cm on the walls on each side.
The thickness of the first layer of waterproofing should be 1-2 mm. The first layer of 4-5 hours dries.
Waterproofing of hydrogen and ramp
If there are hydrogen water on the wall, they should also be waterproofed using a waterproofing cuff.
This is such a rubber gasket. It is put on the pipe and laid in a fresh layer of waterproofing. The gasket is an additional protection in places with high humidity.
Such a cuff is also made on the conclusions of the sewer. It can be made independently from the waterproofing tape.
In the shower zone, the shower ramp should also be increased waterproofing. For this, the place of the ramp is first smeared with waterproofing, then a waterproofing cuff is placed there. After all the manipulations, you can set the ladder.
Waterproofing. The second layer
After the first layer of waterproofing material dries, it is necessary to apply the second perpendicular to the first. After applying the second layer, you should wait a day so that the waterproofing is completely dry. Then you can start laying tiles or other finish coating. The thickness of coating waterproofing in two layers should be about 2-3 mm.
Method of installation of roll waterproofing
The Schulter waterproofing membrane is suitable as rolled waterproofing. The width of the canvas is a meter, the thickness is 3 mm. Rolled waterproofing with epaulet meters is released. If a warm floor is installed in the bathroom, then you can purchase a membrane with special grooves for the cable.
You will also need cement glue C2TE S1 class and isolation tape.
Laying roll waterproofing
First, the floor surface should be cleaned of dust and cement protrusions.
Next, glue with a gear spatula is applied to the floor, and cut mats are placed on top. Further, using the plaster grater, the mat is evenly pressed into the glue. All joints that form between the sheets of the membrane are sealed with insulating tape. The same is done with joints between the floor and walls.
After the waterproofing on the floor has been glued, you should go to the walls. The mats are glued to them in the same way as on the floor. Waterproofing on the wall should be laid on the floor sheets.
After the mat was laid on the floor, tiles can be laid immediately on top of it.
All hydrogen sewers, and sewage conclusions can also be additionally waterproof using waterproofing cuffs.
How to choose a waterproofing for a bathroom
It is easier to work with coating waterproofing. She can quickly smash joints, niches, recesses and other inaccessible places. Rolled waterproofing is not as effective as coating, as it can pass water through the joints between the sheets if they are poorly waterproof. However, it costs cheaper and can be a good option for those who want to save on materials.
