When performing repair of the room or equipping it, waterproofing of walls and floors is obligatory, which allows to protect the bathroom from high humidity and flooding of neighbors in the event of an accident.
In waterproofing,materials are usually used on bitumen, modified copolymers or reinforced polyester materials. Today's products can be bought at any specialized store, both foreign and domestic.
The waterproofing of the walls in the bathroom can be directed and self-adhesive type. In the first version, the laying of material is carried out using special equipment, and in the second, it is attached to the wall due to a special adhesive layer, first applied to one of the sides of the material.
The advantages of this
waterproofing method High performance, long product lifetime, low cost and affordability make it popular in the construction industry.
Disadvantages: the high complexity of the laying process, especially for a small bathroom, large dimensions and weight of a roll, high requirements for the quality of surface preparation, where waterproofing is to be performed, - there should be no irregularities, the wall must be treated with a bituminous primer. Such isolation of the surface of walls and floors must necessarily be closed by screeds. In addition, in the room for a long time, smells of bitumen.
In recent years, waterproofing of the bathroom is increasingly using plaster materials based on polymers and bitumen. Extremely demanded bituminous waterproofing mastics. They are placed on a wall prepared for isolation in 2 layers, which allows to achieve good adhesion with the base, as well as high resistance to various adverse factors. However, to protect the waterproofing surface from mechanical defects, it is covered with a cement sheath.
Polymer-cement mixtures are good construction materials, in which special polymer materials are added. By their structure, they are one-component or two-component type. In the first version, all necessary additives are added to the working mixture, so that after you put on the working surface of the composition, there was an effective and qualitative waterproofing of the walls. In the second one - the components that are responsible for the quality isolation and are in the emulsion liquid, which mixes the dry composition before applying to the working surface.
Advantages of waterproofing materials
Easy to apply - the composition is applied to the wall as a regular plaster solution, and in addition, the mixture has good plasticity, can withstand the appearance of chips and faults in the basis, with no need for additional protection. These components are commonly used to waterproof walls in the bathroom, which adjoin the shower cubicle. The material can also be used when installing warm floor elements.
When performing the work on the waterproofing of the bathroom, the surface of the wall must be thoroughly cleaned of dust and other contaminants that may prevent the moisture from penetrating into the porous structure of the concrete composition. If necessary, you can add some water to the concrete surface of the wall, which will be waterproofing walls and floors, for better bonding. The material is completely inert, it does not contain harmful and dangerous chemicals for humans. The service life of the material is equal to the lifetime of the concrete in the premises itself.
Another popular type of builder is the waterproofing of the walls in the bathroom using a polymer mastic.
This solution is based on organic solvents and polymers. After the second layer was applied to the working surface, the components of the substance are able to communicate well, creating a high-quality waterproof barrier there, forming a special waterproof film protecting against water vapor and high humidity when drying.
The range of waterproofing products based on polymeric mastics is enormous and constantly increasing. Sales of rubber products based on polyurethane resin, butadiene-styrenic acrylic and mastic appeared. They are applied on concrete or plaster basis, gipobetonny walls.
