Waterproofing of the floor in the bathroom: the materials and methods of laying

types of waterproofing

In no case can save on waterproofing. It is fraught with grave consequences. After all material and labor costs might be in vain and claims flooded neighbors unaffordable.

Some would-be builders, to save costs, are placed under the floor instead of special materials thick polyethylene film, wrongly assuming that its ability to pass water not continue infinitely long. This is not true. Polyethylene under the influence of aggressive environment very quickly collapses, turning into fragments that are no longer able to retain moisture.

To avoid these troubles occurred, it is necessary to use materials specifically designed for waterproofing works. These include:

1. Obmazochnye mastic bitumen.
2. Mixtures of cement with polymer additives.
3. Hydroprotection penetrating type.
4. Rubber Gidrobarer.
5. Various roll materials with bitumen base.

They all have different chemical compositions and a method of laying, on which depend the characteristics of the resulting Gidrobarer and technology devices.

Useful advice! Do not skimp on the waterproofing materials. Best suited quality, made famous brand companies. They should have longevity and be environmentally friendly.

bitumastic

This material is a viscous paste based on bitumen. It may contain various chemical additives, the composition of which depends on the manufacturer. Since the bitumen is a fusible substance, the paste ductility increases with temperature, which allows, in terms burner or hairdryer construction, to fill all irregularities of the surface. Such a method is most convenient. When it easier to fill out everything, even the smallest voids in the surface to be treated.

The cement-polymer mixture

Lubricative material type. The waterproofing effect is achieved because it contained polymer particles produced by dissolving in water a liquid-impervious monolith. From the dry mix preparing an aqueous solution of the desired consistency and applied to the surface in multiple layers. In the process hole next to the pipes of communication need to put more of the solution, in order to avoid leaks.

penetrating hydroprotection

This type of waterproofing increasingly used as additional to the core. This polymeric substances that are added directly into the concrete, giving it a waterproofing properties. when done waterproofing the floor in the bathroom, the materials of this type are added to the cement screed device. This technique further ensures watertightness.

Gidrobarer rubber-based

It represents lubricative insulating material based on rubber or rubber. For solidification using reagents supplied in the kit. This type of waterproofing is very convenient to use if the wooden floors in the bathroom. This type is very reliable, because the resulting coating is solid and waterproof. In this case, it is very flexible, it can be used even in the device pool.

Roll materials based on bitumen

The most user-friendly installation of the product. Supplied in rolls and have the form of a film impregnated with one side of the bituminous composition. Glued to the surface by heating to a plastic state by means of a hair dryer construction or the burner. There are self-adhesive film on the basis of. Heat them is not necessary.

Waterproofing and their order

Before we proceed directly to such work as waterproofing bathroom, You must remove all the old paint along with the remnants of the old existing hydroprotection. It should be removed all the way down to the floor slabs. Concrete vacuum desirable to achieve the best adhesion with the waterproofing material.

At this stage, you need to take care of that in the further construction of the floor was lower than 3-5 cm. This will allow in the future to avoid the flood in the apartment, in case of a breakthrough pipeline. Water simply linger in the bathroom as in the pan and will not cause damage to other rooms.

Waterproofing in the overlap of concrete slabs

If the subfloor is concrete slabs, then they need to be carefully filled. Particular attention should be paid to the joints, deep potholes and the place of passage of water supply and sewerage communications. One should not forget about the joints of the walls and floor slabs. Putty is applied around the perimeter of the bathroom. Instead, you can use the cement mixture the desired consistency.

Useful advice! Whatever type of waterproofing is not used, it is necessary to strictly observe the algorithm of its devices.

Further, all depends on the selected type of waterproofing material. If it lubricative, the solution is applied by brush or spatula across the surface of the floor and walls partially to a height of 10-15 cm. Is 2 or 3 layers, depending on what the flashing selected. As a result, the surface must happen-like shower tray. This is to ensure that water does not penetrate the wall.

If you are using roll materials, they are heated burner or building a hairdryer and spins across the floor overlap. At the same time we must not forget about the walls. In order to achieve the best effect waterproofing floor in the bathroom, the two materials combine vidovmozhno. In this case, pasting occurs much more reliable. Particular care needs to be done to work around communication pipes.

When using mixtures based on cement does a similar operation. In the solution screed desirable to add materials penetrating type for increasing the waterproofing effect.

Useful advice! You need to pay close attention to the joints. This is the weakest point in any building. Promazyvat they need more time, not sparing the material.

Waterproofing on hardwood floors

If the subfloor is wooden, the waterproofing device requires extra effort. On cleansed of impurities boards are fixed joists. Then put vapor barrier film on which the heater is placed. It is convenient to use polystyrene foam with a smooth and durable surface. Then, the joints between the slabs and joists are coated via sealant.

Thereafter, the liquid rubber is taken, mixed with an activator and, as soon as possible, a roller is applied to the entire surface, including the lower part of the walls. If necessary, it is possible to apply another coating layer.

When carrying out any of these methods must be strictly comply with the instructions for preparation and application of the solution developed by the manufacturer of the material. It is necessary to pay special attention to these in its drying time. Otherwise, it can lead to the destruction of waterproofing in advance.

It must be borne in mind that all waterproofing materials have poor adhesion to the tile adhesive. For this reason, on top of all the layers is cement with rebar. Only it is acceptable to glue tiles or apply other coatings.

Waterproofing of the floor in the bathroom: Materials

Materials are chosen carefully. Before their purchase is necessary to thoroughly read the instructions. The purpose of this - to find out he is best suited to any floor covering. It should be an ideal combination because inconsistency can lead to difficulties in applying it to the surface.

Having clarified all the features of works on the device of a waterproofing bathroom, you can manually perform this task without resorting to outside help. This will save the budget and will bring invaluable experience of such repair.
