Which floor screed is better in a new building, in the garage? Which kind of screed is better for a warm water floor?

A good quality floor screed is needed for goodrepair. If the floor is uneven, low strength or bending, there will be problems with finishing. Therefore, we must immediately choose which floor screed is better.

The customer needs to think through all beforehandstages of its laying, otherwise there will be a need for additional costs in the process of work. The latter depend on the thickness of the layer, the area of ​​the rooms and the variant of the device of the floor.

Which kind of screed should I choose?

There are the following types of floor arrangement:

• screed of concrete;
• cement;
• self-leveling self-leveling layer;
• the floor is made of wood.

In new houses builders lay the floornot enough quality, so that you can immediately cover the cover. The owner of the apartment, deciding which floor screed is better in a new building, should take this into account and make an equal floor on his own. For this, he has many options.

Wooden screed

In the old houses of the Soviet era, all the floors in theapartments are made of wood. They are easy to assemble, the floor is warm, but the service life is the shortest because of the tendency to rot, burn and deform. Its maintenance is more expensive, as the coating must be periodically painted. When deciding which floor screed is best, you should immediately discard the use of wood. Moreover, many modern floor coverings can be found on the market.

Concrete screed

The composition includes cement-concrete mixture, inwhich can be added expanded clay or pebbles, which makes it stronger. At factories and in garages, metal is reinforced, but for apartments this is not necessary. Against cracks, the use of a polypropylene fiber additive is effective here.

Filling floor

Polymer floor is made more in the form of a thin coating, but can serve as a screed. It includes:

• cement;
• gypsum;
• polymer additives.

Self-leveling floors made of self-levelingBlends from which a perfectly flat surface is obtained. Materials are expensive, but high quality of the floor is achieved. Coating does not require special equipment and high qualification. They are used in office premises, in food enterprises and in places where high sanitary and hygienic requirements are imposed.

For a floor it is necessary to choose vapor-permeable materials, in which structure there is a cement. Then the moisture will not accumulate from below, and the polymer will not peel off.

Semi-dry floor screed

Choosing which floor screed is better, you should immediately pay attention to options with semi-dry compounds. They have the following advantages over wet.

1. Do not waterproof the base.
2. The structure is monolithic, since the beacons are rubbed from the same material.
3. No shrinkage.

The amount of solution is determined after installationlighthouses. To do this, the floor is first screwed dowel-nails to the height of the future screed. The screed is prepared from a mixture of sifted sand and cement in a ratio of 3: 1. It adds a little water, so that it easily sticks together. Estimated amount of peskobetona scattered on the floor and moistened with water. Then it is collected in a pyramid, continuing to add water. For some time the composition is settled, evenly absorbing moisture.

During the entire batch process,Fibrous fiber, which is evenly distributed in the mixture. As a result, the structure of the solution is strengthened and its reinforcement occurs. All work seems laborious, but an experienced team of workers from 5 people for one shift puts a layer 80 mm thick in an apartment with an area of ​​90 m².

Pre-level at the screwed dowelsbeacons are prepared from a smaller amount of sand concrete, and then the screed is laid between them. The solution is compacted and leveled, and then a separate section is treated with a grinding machine. After the joints are cut, allowing shrinkage to shrink while it is gaining strength. In a day, the entire surface is wetted and further work on repairs continues.

Screed for the floor in the garage - which is better?

The garage floor must first withstand the load from the car.

Mechanical effects from it are produced several times a day. In addition, in the garage there are shelves, the weight of which is also significant.

The screed material is also affected by chemical loads from oil products, antifreeze and other liquids. Their hit on the floor is inevitable, no matter how carefully with liquids they are treated.

Paul needs to be done right so that he will withstand allload. This requires a concrete base. Before pouring requires the installation of waterproofing of polyethylene or roofing material. It is mandatory to use reinforcement with a metal mesh or other material. You can lay the stove, but the pouring will be cheaper.

Concrete quickly abraded from above and soakedoil products. Therefore, the floor is covered with ceramic tiles. Usually, porcelain tiles are used, but paving slabs are also suitable. Now, tiles made of rubber, resistant to fuels and lubricants, began to be used. A budget option is painting, but with intensive abrasion, the floor screed must be updated every six months. Which surface is better suited for strength to remain high with minimal maintenance?

An advantageous option is impregnation of the top layer of concrete, which increases the resistance to abrasion.

Which kind of screed is better for a warm water floor?

Before laying the screed, the warm floor needs to be carefully checked and tested, as there will be no access to it later.

And what kind of screed is better for a warm floor in terms of a budget option? This is the application of a conventional solution of sand with cement.

It is prepared independently, only it is necessary to takelarge fractions, since the mixture is stronger. It adds a plasticizer, which can be purchased at a construction store. It is advisable to use special mixtures that already have all the additives. As a result, any places are filled where access is difficult and voids are not formed. The mixture should be diluted with water according to the manufacturer's instructions. The basis is the gypsum, which allows fixing the screed within a week. For the use of each composition, its own instruction is suggested, but there are the following rules common to all gypsum mixtures:

• a proportion of water is required such that the solution is creamy;
• the thickness of the fill should not exceed the allowable;
• in rooms with high humidity, the surface of the screed and the place of abutment to the walls are covered with a waterproofing composition, since gypsum does not tolerate a prolonged exposure to moisture;
• the thickness of the layer above the surface of the pipes is usually 45 mm, and when self-leveling mixtures are used, up to 25 mm;
• Before installing the floor heating it should be determined whether the flooring will withstand a 65-70 mm thick screed;
• in places of installation of heavy items, the screed is additionally reinforced with a metal net or fiber.

The stacking technology does not differ from the usual one. In this case, do not move the laid pipes, because subsequently it will be difficult to repair the damaged location. The screed is the basis for the floor covering, so the surface to be created must be flat and smooth.

Conclusion

When laying the screed, you must follow the sequenceworks, the correctness of technology and take into account the features of the premises. Materials should be of high quality. Understanding what kind of floor screed is better in this or that case will make it possible to do the work yourself and save money.
