The bathroom is an individual microclimate. This room is characterized by frequent temperature fluctuations, constant high humidity and condensation. The walls of most bathrooms are made of brick or concrete, which have a porous structure and always need to be protected from moisture and subsequent destruction.
Any finish has a certain percentage of moisture saturation and moisture loss. During the operation of the bathroom, hot steam, water, and moisture penetrate into the tiles through the intertile joints.
This process happens very slowly and can take years, but after a certain period of time, the tile, marble or granite is completely saturated with moisture.
Marble and granite get absorbed more quickly, and ceramics a little longer, but after the tiles are completely saturated with moisture, they begin to give it to the plaster mixture, which in turn gradually swells and loses its adhesive properties with the tile, and as a result the plaster layer is destroyed, walls and mold can appear in places.
To walls do not attack fungus and mold in 2 months after repair – apply a special material under the screed. Properly selected waterproofing bathroom will perform the following functions:
- Prevent the destruction of the finishing material. With constant exposure to moisture and steam, even the most durable sources lose their appeal, become unusable.
- If you live in apartment the bathroom waterproofing will prevent flooding of the neighbors from below. Only possible if properly installed.
- Will protect not only from internal moisture in the room, but also from external moisture. Such protection is appropriate not in apartment buildings, but in private homes.
- Bathroom waterproofing is simply necessary when installing “warm floors”.
Types of waterproofing
There are many types of waterproofing. The most popular options will be described in this article. But we want to clarify that there are other methods: penetrating, injectable and sprayed. We do not describe them for simple reasons: they are effective, but expensive. Those options that we will point out in the article, it is more rational to use. The other methods of insulation are justified in rare cases.
The main requirements for the quality of moisture protection
One of the most important conditions for a long trouble-free service waterproofing coating – its tightness. Therefore, the treatment of surfaces with materials of the coating type is required in a limited time interval. Thus it is possible to ensure a crack-free coating. The material itself, respectively, is made immediately before the application and apply two or three layers of waterproofing. This laying will greatly increase the reliability of the connection of materials. Remember that the application time is limited, it is necessary to read the instructions.
His secrets are and y coverage of walls with laminated waterproofing. If it was decided to use roll materials, they are laid with an overlap, the standard size of which is 10 centimeters. But it is better to clarify the size specified by the manufacturer. Be sure at this method of waterproofing approach to the walls to isolate the joints.
Quite seriously worsens the quality of moisture protection ignoring the scraping of surfaces. This procedure, as well as priming, is required for any chosen type of waterproofing. Any preparation for waterproofing the surface consists of cleaning the substrate to concrete and levelling with a primer. Priming not only improves the coefficient of adhesion, but also used in order to save money, because it significantly reduces the consumption of expensive materials. Plus, the use of primer mixtures increases the drying time of surfaces. Do not forget to carefully work the corners for better adhesion to the surface. In this way you achieve a proper waterproofing for the bathroom renovation project.
Waterproofing of the bathroom in a wooden house
Wood is an organic material that swells when exposed to a humid environment and will gradually deteriorate over time.
Due to constant temperature and humidity fluctuations, the walls in buildings made of timber often “dance”, as under the influence of various factors, the timber can swell and shrink.
The bathroom in such a house should be as airtight as possible in relation to the rest of the premises. Before the arrangement of the wooden floor on the joists, the foundation of the house is waterproofed with mastic or cement-polymer composition. Beams are treated with antiseptic and thoroughly dried.
Before laying the floor wooden boards are treated with one of the waterproofing compositions. To do this, use bitumen or primer varnish, which have a high degree of elasticity (shrink and expand with deformation). Parquet varnish is used after the installation of wooden floors, it protects the outer surface of wood from moisture. The same means treat the walls and ceiling of the bathroom, paying special attention to the joints or corners. If the walls are made of plasterboard, before applying a waterproofing layer, it is treated with moisture resistant impregnation.
Conclusion
After studying the technology, you can make waterproofing of the bathroom under the tile yourself, or entrusting this important matter to professionals. In any case, an important role in the arrangement of the waterproofing plays an important role is the composition applied.
