Substrate Preparation

first step in laying the waterproofing is dismantling the old floor covering and sealing of joints between floor slabs.Old screed is removed before the concrete slab, swept out all the garbage and construction dust is removed.Net base coated with a primer to improve adhesion between the materials to be applied.All seams between the plates and the angles between the wall and the slab smeared cement mortar.

Note!For cement works can be used cement grade M 100 .

Particular attention should be paid to the place in which there are risers water, because this place is the most exposed to the flow of water.If the pipe is in the sleeve, the problem is simplified, if it does not exist or is too short, you will have to do it or to build.In this case, no welding work is indispensable.Holes are punched for wiring pipes, must be carefully removed.Use rags and assembly foam is prohibited, all should be to seal grout.

Laying waterproofing

Waterproofing applied to the cleaned and primed surface.First poured asphalt mastic.She has all the angles are coated, and in places the water communication should be to fill in all the cracks.In addition, a height of 20 centimeters and desirably fluff wall.The challenge is to bitumen waterproofing and create something like a trough, which will not pass water.In the process of drying mastic is necessary to make sure that it is not exposed to dust.

After drying putty, a day later, begins the installation of waterproofing layer.You can use the roofing material or special materials.The choice of material depends on your financial capabilities. Tip!On the choice of material for the waterproofing is better to consult with a specialist.

material is cut into pieces 30-40 centimeters wide, that there was an overlap on the wall.Overlay material on the walls is very important, because without it will not do the same "trough."In addition, adjacent bands being put must overlap each other by 15 centimeters.When all of the material is laid, it is necessary to stick to the plate and walls.To better secure the sheets need to reheat the gas burner.Making the floor in the same manner and the glue material to the walls.At the end of the pipe again filled with bitumen.Now is screed in the bathroom, on top of which is laid tile.

floor waterproofing in the bathroom - avoid errors

addition to all of the above must be added a couple of important nuances.Ready bathroom floor should be at a level slightly lower than in the rest of the apartment.This allows in the case of flood water holding only in this room, and it does not cover the remaining rooms apartments, because there is no waterproofing.Therefore, calculating the thickness of the screed, this time should be taken into account.

Note!If you can not make the level of the floor below, it is possible to put at the entrance of the high threshold, which will act as a barrier role.

second point - it does not listen to the advice of friends and "masters" on various Internet forums, which recommend to use cellophane tape as a waterproofing material.Whatever it was not dense and thick, you can not stick to the quality of its concrete floor and walls.The slots that are left, will bring to naught all the efforts of the waterproofing.These two points are a common mistake amateurs, so consider them if you want to make a high-quality protection against moisture.
