Self-contained waterproofing shower cabin

Having planned the installation of the shower enclosure, it is worth paying careful attention to its correct waterproofing and take care that moisture can not penetrate the concrete floors. In the future, this will prevent leaks, flooding the bathroom and neighbors, the appearance of fungus and mold on the walls of the room. In addition, the correct waterproofing of the shower cabin can ensure optimal hygienic conditions, which will positively affect the health of the person using the bathroom.

The process of waterproofing the bathroom

When you use the shower in the bathroom, you must carefully monitor the quality of the waterproofing.

Materials for waterproofing

The correct choice of materials for waterproofing the shower should be based on information about what the walls, floors of the room and the shower itself are made of. Usually one material is enough for sealing, but the best result can be achieved by applying a comprehensive waterproofing using each of the materials in this or that part of the bathroom and the shower enclosure in particular.

All types of waterproofing can be conditionally divided into:

  • coating options;
  • penetrating waterproofing;
  • use of roll materials;
  • use of polymer-cement compositions;
  • flexible type of waterproofing.

The roll-on waterproofing is made with the help of reinforced with polyester or fiberglass bitumen with the addition of polymers. They are both self-adhesive, laid without the use of any additional devices, and fusible, which are mounted using a gas burner. Such materials can be waterproofed both walls and floors. When installing surfacing roll materials, a special burner is needed, which is not for everyone, and it is not very convenient to work with it in a small room. But the main drawback of this method is the high demands on the surface. Its irregularities should not exceed 0.2 cm, and sharp clefts are categorically unacceptable.

The lubrication version is more modern than the previous one. These are different bitumen-based mastics. This type of insulation is also called liquid rubber. The main advantages of this method include a high degree of elasticity, good adhesion with an insulated surface and a long operating gap. They are easily applied to flexible and rigid substrates. For reliability, a cement screed is placed over the lubricating seal.

Waterproofing material

Particular attention should be paid to choosing a quality waterproofing material.

Polymer-cement compounds look like a dry mixture, which must be diluted with water. This method is suitable for both walls and floor, besides a high degree of elasticity eliminates the need for an additional screed.

Polymer mastics make it possible to isolate showers and bathrooms from moisture and liquids at a sufficiently advanced level. The composition penetrates deep into the surface to be treated and gives high water resistance.

It is important that cement-polymer mastics are resistant to high temperatures and are well combined with a warm floor system.

During installation work it must be taken into account that any bathroom has places that are more prone to destructive effects of water. These include walls and floor, joints between them. For them, a complete waterproofing is necessary.

The floors need to be insulated with the approach to the wall covering at least 20 cm. This is because the joints between the floor and the wall are most vulnerable to moisture and it is from here that the concrete wall is destroyed.

Directly the shower itself needs a waterproofing 20 cm above the shower head, but to avoid unforeseen situations, it is better to seal it to the ceiling. When waterproofing the side walls of the cabin, it is advisable to insert a waterproofing material not less than 0.5 m beyond its limits. Also to the wet zones include risers with pipes. The remaining surfaces can be attributed to the wet zone.

Shower base

First of all, you should clean the surfaces of dirt. All garbage must be swept out and dust collected by a vacuum cleaner.

Next, you need to install a sink for the pallet, treat the stub seams with a moisture-proof sealant. Then you need to align the floor to install the cab. Otherwise, a lot of insulating material can escape.

On the base for the pallet are glued foam polystyrene plates, which insulate the structure and protect the pallet from the capillary suction.

Next to the expanded polystyrene is glued the mounting net, the screed of the shower tray is poured. After it has dried, all the cracks, edges and corners are filled with a sealing material, for example, liquid rubber. Liquid rubber is applied to the concrete screed of the shower tray, and it is better to do this in several layers. The required number of layers and the drying period must comply with the recommendations in the attached instructions. It should be remembered that the application of layers of composition is carried out "cross-wise".

After that, you can fix the finishing materials and put a shower. You can pour water on the structure and make sure that moisture remains on the floor.

Sealing of walls

At the first stage, it is necessary to clean all concrete and stone surfaces with a wire brush, if necessary, use special cleaning and dissolving compounds. Metal, plastic and glass areas should be wiped with a solvent or alcohol-based liquid, then wipe them dry with a tissue. To avoid contamination of areas adjacent to the sealed seam, it is better to use an adhesive tape, which must be removed immediately after the work is finished.

The surfaces to be treated must not be too cold or hot. Their temperature should vary between 5-40 ° C. The tube with the sealant is heated to room temperature. The method of application is determined by the instruction. To form a beautiful seam and remove excess silicone, it is better to use a spatula soaked in water. To remove superfluous should be very operatively, as the film on the surface of the sealant appears within 5-30 minutes depending on the composition. The average rate of solidification of the material is 2-4 mm per day at a humidity of 50% and a temperature of 20 ° C.

All work should be carried out only on a dry surface. First, you need to assemble the shower enclosure in accordance with all the instructions in the manual: install the side panels, fixing the guiding profiles with screws, fixing the top part and the hose.

At each assembly stage, all joints and joints must be lubricated with a sealant. It should be observed that the holes for the screws and screws are outside, then during the final assembly the sealant layer will remain intact.

Stitches covered with silicone are fixed with screws and left until completely dry. Surplus sealant is carefully removed with a rag. Do not wait for complete hardening.

Next, the shower enclosure must be insulated from the outside with a sealing cord. It should be inserted into the junction of the frame with the glass and additionally treated with silicone to improve the waterproofing properties of the problem areas.

After drying the structure is tested for tightness with a strong head of water, it is necessary to pay attention to all joints.

If there are leaks, you should once again walk through the sealant in all the flowing zones.

This should be done only after the cabin has completely dried on the "problem" places.
