Types of waterproofing

The process of working on waterproofing in the bathroom is to create a water obstruction from a material that does not allow moisture to pass through - it is applied between the base of the walls or floor and the decorative coating. From zones of moisture protect all areas on which water may fall.

Important! First of all, do-it-yourself waterproofing in the bathroom should be on the floor under the bath, washbasin, washing machine, around them. Also pay attention to the walls that are adjacent to the sink. In general, in places where moisture penetration is most likely, they are also called “wet zones”.

To protect such “wet areas” use the following types of waterproofing.

Okay

This type is associated with the use of rolls or sheets of waterproofing material based on cardboard, impregnated bitumen or synthetic fabric. Under the influence of high temperatures, the sheets are heated, giving them plasticity, and deposited on the surface of the walls or floor.

Important! It is inconvenient to use this option in the bathroom, because the gas burner, which is needed during the gluing process, is not designed to work in unventilated and cramped rooms. Making waterproofing in the bathroom with your own hands in this way is quite difficult.

Painting

To carry out waterproofing of this type, bitumen or polymer mastic is used. This material seals moisture penetration paths well. Processing is carried out in several layers with obligatory drying between them.

When processing bituminous mastic emits an unpleasant, pungent odor, but polymer - is environmentally friendly, respectively - more safe.

Important! The drying time of modern mastic for waterproofing is 2 hours.

Smear

When organizing waterproofing in this way, a polymer mixture, which consists of cement, fine quartz sand and special polymers, is applied to the surface to be protected, like plaster, using a spatula and trowel, coating floors and walls. Processing is carried out in several layers with obligatory drying for 6-8 hours between them.

Important! Do-it-yourself waterproofing of the bathroom is considered to be done correctly if, after the work is done, the so-called “hydrocutter” is obtained, which completely covers the floor area and captures the walls to a height of about 30 cm.

2. Clean the room of debris, large - notice, and eliminate dust with a damp cleaning.
3. Carry out an audit of the condition of the floor, all cracks found, close the recesses with a moisture-resistant cement mortar. Make the floor as flat as possible.
4. After the solution is completely dry, sand where the alignment has taken place.
5. Then apply a special primer. Wait until it is completely absorbed.

2. Pre-lay the roll material on the surface by cutting it into strips of the length you need. In the process of trimming, it is necessary to leave a margin of 15 cm on each side.
3. Put the sliced ​​pieces on the floor lap, while not leaving gaps without material. There should also be no gaps at the joints between the floor and the wall.
4. Seal the joints with sealant, and roll the edges with a roller for a better fight with bitumen impregnation.
5. If you decide to fill the screed over the waterproofing, and not before it, then at this stage you should do the work to complete this task.
6. After drying, the surface can already be tiled with tiles or other finishing materials.

4. In a bucket or some large capacity, dilute the mixture, following the instructions, using a construction mixer.
5. Apply the mixture in a thin layer to the surface and let it dry completely.After this, apply the composition again and also dry.
6. After complete drying, you can start decorating.

Important! For ease of application, it is better to use a roller or a wide brush, and also work with rubber gloves to prevent the substance from getting on the skin.

• It is necessary to identify the possible cause of increased humidity in the room, if possible, eliminate it.
• The surface of the walls should be prepared, that is, cleaned of dust, dirt, adhering building materials.
• It is necessary to treat the base with a primer, which contributes to a better penetration of waterproofing deep into the wall material, and one that provides strong adhesion of adjacent layers.
• Seams are best protected with a two-component sealant.
• Treat walls with waterproofing layers in layers.

Joining joints between the bath and the walls

After the equipment is installed in the bathroom, a whole series of operations are carried out to waterproof the joints, which are formed in places where the walls of the room come into contact with plumbing fixtures.

All cracks, which experts call butt joints, are well insulated. This makes it possible to reduce the likelihood of moisture entering the floor or walls of the bathroom.

Important! The choice of waterproofing material is determined by the size of the slots. Narrow gaps are sealed with a special antifungal sealant, and wide - with a self-adhesive sealing tape.
