  • roll or overhead;
  • oiling.

Roll form of waterproofing can be divided into self-adhesive and fusible. In order to lay the first species, it is necessary to prepare a perfectly flat surface without defects. Before laying the insulation material, the surface must be cleaned of dust, debris and residues of the old floor covering. It is recommended to cover the base with a primer layer, this will significantly increase the adhesion. In order to use the second material, you will need a burner with which the material will be heated. The disadvantage of this material is the unpleasant smell of bitumen.

Waterproofing the floor with your own hands can be very simple, if you use the coating materials. In order to apply them, you do not need to prepare the surface. In addition, lubricating waterproofing has excellent properties and can withstand high temperatures or sharp jumps.

The coating type of insulation can be of the following types:

  1. Acrylic is a water-based waterproofing. Its popularity is determined by ecological purity, absence of unpleasant odor and high strength.
  2. Bitumen is one of the oldest species. He proved himself in Soviet times. Can be a cold and hot type of application. The affordable price of the material makes it very popular in various areas.
  3. Bitumen-polymer. Ideal for floor insulation in the bathroom.
  4. Polymer-cement. Very convenient to use.

Sometimes there is a problem in which the entire surface can not be processed. In order to carry out the repair work correctly, it is worth paying special attention to individual sections of the floor, which must necessarily be isolated from the possible penetration of moisture.

The insulation of the floor is not limited to the base only. If the work is done properly, the insulating material should go to the wall, to a height of at least 20 cm. Special attention should be paid to the corners and joints. It is in such places that water seeps, forming foci of fungi and mold development there.

It is important to process the walls near each piece of sanitary ware: a bathroom, a wash basin, a shower and a toilet bowl.

Specialists recommend, if possible, the necessary treatment of the walls throughout the bathroom. This will protect them from fungal attack.

  • brush or roller to apply a primer;
  • Brush for applying insulation material.

The work will begin with surface preparation. In order to work was much easier, it is worth to take out all available in the bathroom plumbing fixtures and other pieces of furniture. It is very important to carefully remove the old floor covering and clean the entire surface from the adhesive layer. After the entire surface has been cleaned, it can be covered with several layers of a special antiseptic primer.

It is very important that it is dried before applying the insulation layer.

The drying time is indicated on the packaging, on average it is about 4-6 hours.

The next step is leveling the surface with a concrete solution. Do not make a too large layer. The finished concrete screed should be twice covered with a primer. Waterproofing of the floor starts from the corners, for this you can use a special tape. She completely pasted the corner and joints. Then the entire floor area is applied to the insulating material with a roller or brush, do not forget about the walls.

Rolling materials

In order to lay this kind of isolation, it is necessary to take a very responsible attitude to the preparatory work. If the surface is defective, they may damage the insulating material over time. Therefore, without fail it is necessary to make a concrete screed. To work with such an insulator you need a minimum number of tools:

  • To cut the blade, you can use a scissors or a knife;
  • A spatula can be used to apply the adhesive solution to the substrate.

If a self-adhesive material is used, it is only necessary to remove the protective film and apply the cloth to the base. In order for it to get stuck better, the surface should be smoothed with an ordinary roller. If the roll insulation is not self-adhesive, it will be necessary to use a special adhesive compound, which will subsequently be applied to the substrate. The glue is applied with a uniform thin layer without sharp changes, which can subsequently appear outward. Regardless of the type of waterproofing material, all sheets need to overlap at least 5 cm, this will provide greater protection. All joints are very important to glue together, for this purpose, glue or a special glue tape can be used. Thus moisture can not penetrate the canvas.
