Without water, it is impossible to make hygienic procedures, take a refreshing shower or luxuriate in the bathroom, but excess moisture for any building material is evil. Wood, metal and concrete gradually under the onslaught of liquid turn into dust, covered with mildew or rust, and the room assumes an unsightly appearance. From flooding, suffer, as the owners of the bathroom, and neighbors, which spoils the mood and leads to scandals. Alas, but the beautiful tile of all problems will not remove, the liquid can seep through the seams and thick walls, penetrating into the neighboring rooms.
How to make waterproofing in the bathroom?
In short, all such events are reduced to one goal - to turn the floor in this room into a kind of moisture-proof pallet with boards that will withstand not only spilled liquid accidentally, but also a small flooding. It is clear that ordinary cement mixtures or polyethylene can not give such an effect, special materials and impregnations are needed here.
Materials for waterproofing the bathroom:
- Bituminous mastic.
- Rolled or sheet moisture-resistant materials (self-adhesive and fused).
- Cement-polymer mixture.
- Gidrobarer, which includes rubber.
Which waterproofing of the bathroom is better?
In the old days, the coatings were animal fats or oils from petroleum products. Now they are sold in the form of dry mixtures, which are diluted with water or a special emulsion based on polymers. There are also ready-to-use pastes or liquids supplied in sealed jars. Thick paste is conveniently applied with a notched trowel, and more liquid formulations with a brush.
With roll materials, it was always easier to work, but there are some features. The fact is that the insulation sheet needs to be docked very accurately, and the working surface itself should be level. Differences greater than 2 mm are not allowed. The materials to be welded during gluing release a lot of volatile substances with a persistent smell. They need to be hidden under a strong screed. Among the advantages of roll waterproofing, it should be noted its affordable cost, the strength of the rough floor, the absence of a break between the stages of work. One kind of such materials needs to be heated while gluing with a hair dryer or a burner, and the second subgroup has a special adhesive layer covered with a protective strip. The non-specialist, and even in an enclosed space, with this roll material is easier to work with.
Given all the above nuances, we agree with the competent conclusions that only complex protection is capable of giving the best result when roll materials are used together with lubricants.
Waterproofing device in the bathroom:
- The surface of the floor and walls is cleaned of debris and dust. After wet cleaning , if necessary, the area to be treated is dried.
- A primer of deep penetration is applied to the floor. There are compounds that can already partially cover the pores in the concrete, forming a kind of layer of waterproofing.
- On the dried after the priming of the floor, we apply bitumen mastic. Usually, this process begins with a joint between the walls and the floor in the bathroom. The floor is covered with this compound completely, and the walls - to a height of 20 cm. Rubber seals on pipes are also lubricated with mastic.
- Then we lay roll material. All the strips are placed with an overlap and bring them to the walls. The formation of gaps is not allowed.
Joints are well smeared with mastic. Heating the sheets with a burner improves the plasticity of the material, and the coating is better suited to them. - After treatment, the room is dried and closed for this period.
- After the waterproofing of the bathroom is finished, you can make a screed, level the floor and lay the tile .
To think during the repair whether waterproofing is necessary in the bathroom, it is not necessary for a long time, it is necessary to immediately carry out a complex of works that can insure your housing against expensive and unpleasant "wet" surprises.
