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

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

The customer needs to think through all the stages of its installation, 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 floor not qualitatively enough that it can be immediately covered with coverings. The owner of the apartment, deciding which floor screed is better in the 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 the apartments 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, because 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 a cement-concrete mixture, into which it is possible to add expanded clay or pebbles, which makes it stronger. At the enterprises and in the 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 are made from self-leveling mixtures, 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 where high 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 best, 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 the installation of beacons. 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 coalesces. The estimated amount of peskobetona scattered on the floor and moistened with water. Then it is collected in a pyramid, continuing to add water. Some time the composition is settled, evenly absorbing moisture.

During the entire batching process, fiber fibers are added, 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 of 5 people for one shift puts a layer 80 mm thick in an apartment with an area of 90 m ² .

Preliminary, at the level of the screwed dowels, beacons 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 are placed 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 correctly so that he can withstand all the stresses. 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 soaked in oil 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. The budget option is painting, but with intensive abrasion, the floor screed must be updated every six months. Which surface is better for the 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 on its own, only it is necessary to take large factions, 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 where access is difficult and voids are not filled. 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 instructions are suggested, but the following rules are common for 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 contiguity to the walls are covered with a waterproofing compound, 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 a warm floor, you should find out whether the flooring will withstand a 65-70 mm thick screed;
• In places of installation of heavy objects, the screed is additionally reinforced with a metal net or fiber.

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

Conclusion

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