Waterproofing before the floor screed in the apartment with their own hands. Materials

If you decide to carry out a major overhaul of the apartment, then you need to start it with the arrangement of the floors. If you need to lay a new floor covering, then before this you must make a screed. However, this work should be prepared. That is, waterproofing should be carried out before the floor screed in the apartment. How and what to do, you will learn further.

What is the procedure for?

The presented process must be made necessarily. Such protection will ensure a continued and effective use of the premises. That is, if you have problems with the water pipe or the faucet and the water flows directly to the floors, you will have the opportunity to avoid conflicts with neighbors that you will flood. Without isolation, the liquid will leak even through the most durable layer of concrete.

Please note that the waterproofing before the floor screed in the apartment should be carried out in all rooms, not only in the kitchen and bathroom. The fact is that in a concrete solution, which you will level the surface, too, contains a large amount of moisture. If the liquid will evaporate gradually, which provides hydroprotection, the screed will be more durable and of high quality.

Thanks to this procedure, you will be able to protect the room from excess moisture, spreading fungus and mold.

Features of the coating

Waterproofing before the floor screed in the apartment has certain nuances:

1. If your home is located on the first floor and there is no basement under it, then protection should be made as high as possible. The fact is that ground moisture contributes to rapid destruction of concrete.
2. Before carrying out the insulation, the floor surface can be leveled with a special mixture.
3. If there is a redevelopment of the room, which can be carried out with the demolition of partitions or walls, then only after it is laid the tread layer.
4. It is best to make a full waterproofing floor. Partial will not give the desired effect, and the water will still find where to seep.
5. If the room has a high level of humidity, then you need to protect not only the floor, but also the walls.

Types of insulation

Before it is waterproofed before the floor screed in the apartment, you need to understand what it is worth using. There are such types of materials:

1. Roll. Most often in this case, a ruberoid or fiberglass is used.

2. Membrane. Most often this material is polyethylene. It has a low cost, but it can not be called strong, as it quickly breaks.

3. Liquid bitumen solution with additives. It has a fairly high cost, but it is very easy to install. In this case, after drying, it forms a very strong layer, which does not allow liquid to pass through.

4. Stucco. Such mixtures consist of cement and various kinds of additives. Naturally, such a substance will need to be diluted with water and applied with a spatula.

In addition, the floor waterproofing in the apartment before the screed can be applied in such ways:

• Spreading;
• By spraying;
• Pouring;
• Spreading;
• Gluing.

Preparation for waterproofing

Now we need to understand what needs to be done before implementing such a hydroprotection. Preparatory work will include the following actions:

1. Complete cleaning of the premises from debris and dust. The room must be absolutely empty.
2. Leveling the surface with special repair mixtures.
3. Preparation of tools and materials for work. For example, if you decide to use roll barriers in cold weather, then you need to put them into the warm-up space for a while. Only then you can get started.

Features of roll protection

So, let's look at the details of the procedure. Waterproofing the floor in the apartment before the screed (materials that are used in the work, you already know) should be done in stages. If you decide to use roll materials, then the procedure for laying them has these features:

1. First you need to spread the coating on the floor. For maximum protection it is better to use a couple of layers. Note that at the junction of the horizontal and vertical planes, the web should go to the wall for another 15 cm from the floor.

2. Please note that this protection must be continuous. If you have to use several pieces of material, then it must be overlapped, and it should be 20-30 cm.

3. In the corners, the product must be folded neatly.

4. In order for such protection to be effective, the joints between the layers of material should be smeared with bituminous mastic.

How to make insulation coating?

If more serious protection is required, then it is better to use mastic. In this case, the stage with the alignment of the surface can be safely skipped. You will not need any special equipment or additional tools. Waterproofing the floor in the apartment before the screed (the photo of the process you can see in the article), thus, involves the use of dry substances, for the preparation of which requires water. In addition, it is possible to use ready-made liquid formulations.

Naturally, before starting work, the floor should be thoroughly cleaned and covered with a coat of primer. Further, a special tape needs to glue the corners and joints, where the probability of percolation of moisture is highest. Next, prepare a solution.

Apply very carefully to the floor and walls, in the case of the latter - to a height of about 35 cm. To do this, apply either a roller or brush. Strongly rub in the floor or smear the composition is not necessary. After grasping the first layer, it should be moistened and the second layer applied. And they must fit perpendicular to each other. It is enough to apply only three layers.

In the event that the mud floor waterproofing in the apartment before the screed ("Hydroisol", for example) will be successful, you can pour it with prepared concrete.

How to make insulation with a wet screed?

As you can see, the waterproofing of the floor in the apartment before the screed by oneself is carried out quite simply. You just need to get used to it. Many readers are interested in how to make a hydroprotection with a wet concrete screed. It's very simple.

1. Clean the surface, and then apply a primer solution.

2. After it dries, you need to detect and repair all the cracks and holes in the sand-cement mix.

3. Now you can proceed to cement waterproofing. Using a trowel, apply it to the floor. Observe the same layer thickness throughout the area. After it dries, apply at least 3 layers of mastic. To fully dry such a waterproof, you need at least 6 hours.

Please note that this method can only be suitable for rooms that differ in normal or low humidity.

Some nuances

Regardless of which material for the job you choose, each process has its own subtleties, which should be taken into account:

1. Each layer of mastic for good adhesion should be applied no later than 3 hours.
2. If you decide to use roll materials, then you can choose products on a sticky basis. This will greatly simplify and speed up the styling process.
3. Polyethylene or polypropylene barriers are most often used if they serve as the basis for a wooden floor.
4. Mastic is the most commonly used material, which allows not only to protect the room from moisture, but also to partially level the surface to be treated.
5. A peculiarity of liquid insulation is that after drying it turns into a thin, but reliable protective film. Its thickness should not exceed 3 mm. The submitted material is applied with a brush, but this protection will have to be updated every 5 years.
6. If you decide to choose a method for melting the composition on the floor, then you will have to purchase a gas burner. Naturally, this method is quite labor-intensive and even fire-hazardous.

As you saw, the waterproofing of the floor before the screed (the materials also had time to consider) is carried out quite quickly and simply. You can manage this task without recruiting specialists.
