Waterproofing the floor in the bathroom under the tile

The bathroom is engineering-sophisticated. In conditions of a large number of plumbing fixtures and high humidity, protection is indispensable. The insulation of the surface under the tile must be planned at the stage of major repairs of the room. In order to conduct quality work, you must adhere to the rules and regulations.

What is floor waterproofing

The bathroom floor consists of numerous layers, which should be protected from destruction and the appearance of fungus. To do this, apply waterproofing technology. The principle is to create a protective layer from materials with a special composition that protect against excess moisture. Due to the fact that the bathroom contains communications, it is necessary to correctly create a sealed layer in all corners and joints.

 Reference.All materials are manufactured in accordance with accepted standards and norms. Quality products must meet safety requirements.

During the overhaul, it is advisable to make a complete waterproofing. If this is not possible, then a partial option is suitable. In this case, only a surface with high humidity needs to be treated.

Main areas:

• location of the sewer and pipeline;
• area under plumbing products;
• pipe connection and other communications.

There is a wide range of products for floor waterproofing. Each material differs in technical characteristics and installation method.

The main varieties:

1. Coating type is a viscous substance that is applied to the surface. Due to the content of polymers, after drying, a durable, damage-resistant and airtight surface is obtained. In the production, bitumen is also taken as the basis for the coating material. It is more affordable, but less durable.
2. Roll waterproofing is a classic option. Modern rolled material is made from advanced bitumen. No special burners are required during installation. The composition also includes synthetic yarns to increase strength and improve the elasticity of the material. With proper installation, you get a smooth and durable surface.
3. Jam waterproofing option made of cement and polymer additives. The material hardens after drying, creating a dense protection. It is recommended that after pouring, wait a day before starting to lay the tiles.
4. Filling type is an expanded clay material. Due to the high load on the floor, it can only be used in private estates and on the first floors of a high-rise building.
5. Stucco mortar has a viscous structure with additives. Thanks to its special composition, the surface will have water-repellent properties. The insulator should be applied in several layers.

The type of waterproofing is selected depending on financial capabilities, the type of floor and the technical features of the bathroom.

Do-it-yourself waterproofing the floor of the bathroom under the tile

Before starting work, it is necessary to free the room from excess garbage. The reliability of the surface depends on the quality of the preparatory phase.

Important.If there is a waterproofing layer on the floor, then it must be removed. Application of the substance over the old surface will lead to a decrease in stability and tightness.

If there are chips and crevices on the floor, they must first be coated. It is necessary to create a flat and smooth surface. With a deviation of the height of more than 2 mm, there will be problems in the process of laying tiles. When the room is ready, you can proceed to the main stage.

Step-by-step instruction:

• Before starting work around the perimeter, the joints are sealed with ribbons. They are necessary to strengthen and protect the screed from destruction. It is required to carefully lay the material, and check the quality of work.
• Depending on the type of waterproofing material, prepare the necessary tool. To apply the liquid solution, you need a roller, brush and a suitable container. In order not to knead the mixture manually, a drill with a nozzle is useful.
• If there are corners in the floor from pipes and sewers, then they should be processed. Around the perimeter use tape to seal the joints. Thanks to the mesh structure, a strong and flexible material is obtained.
• Before applying the waterproofing material, the surface must be primed. The composition is applied evenly and thinly. Next, let it dry.
• Mix the composition immediately before application. Using a drill with a special nozzle, the composition is prepared according to the instructions from the manufacturer. You need to apply small revolutions. With large bubbles may form.

 Attention.When stirring, all proportions should be strictly observed and the manufacturing technique should be followed.

• The next step is coating. To do this, you need a spatula or a stiff brush. Gently and evenly apply the composition to the entire surface of the floor. It is also necessary to coat 5-10 cm of the walls around the perimeter for additional protection.
• After applying the first coat, it must be allowed to dry. Depending on the composition, the time of complete drying varies between 10-12 hours. The second layer is laid similarly. It is necessary to create a flat surface without chips and dents. If necessary, apply another composition.

When choosing rolled waterproofing, after installation, drying of the surface is not required. You can start laying tiles immediately. The coating and filling type require drying up to 24 hours.

Pros and cons of waterproofing

Excessive humidity is constantly present in the bathroom. Therefore, materials should be protected and destruction prevented. The use of waterproofing technology during repairs has several advantages.

Pros of this method:

1. High tightness of a floor surface is provided due to the polymeric substances which are a part.
2. Waterproofing is able to protect the tile from the appearance of fungus in hard to reach places.
3. Additional floor leveling is due to viscous materials. In this case, the tile will be more securely fixed.
4. Extension of the service life of plumbing equipment and pipe communications.
5. Simplicity in installation technology and a large selection of materials for surface treatment.

Among the many advantages, there are minor flaws. Installation of waterproofing will require additional costs for the purchase of materials, as well as increase the completion time for several days. Applying insulation to the tiles is a simple process, but if you wish, you can contact a professional team.

During renovations in the bathroom, carefully insulate the tiled floor. Excessive moisture can destroy the coating and lead to mold. Modern materials consist of substances that are safe and resistant to damage. You can install and apply the waterproofing layer yourself. It is required to follow the basic rules and not violate the process. The result is solid work.
