In order to align the base of the floor, a conventional cement-sand screed or a bulging floor is often used in repair work.
The work process is very similar to each other, but the materials have a different value, and the components themselves differ from each other by their operational capabilities.
In general, the filling floor instead of a screed can be used, but the basis of the floor is still a classic screed based on sand and cement, which allows you to approximate the floor.
Material selection: Advantages and Disadvantages
Be sure to drive the floor before starting the main work
To compare the types of floors is best as it work from the very beginning, therefore, if the concrete slabs lie on the floor, it will take:
- Make preparatory work and carry out the progress of the foundation. Poons are soothed in the stoves, all the protrusions are removed by the perforator. This procedure is necessary for any material used.
- Then you need to leave the floor for a certain period of time, so that the soil is dry.
As can be seen, the preparatory work is the same and do not differ from the materials used.
To deal with the fact that better bulk floors or screed for aligning the plates should be taken into account the difference in the materials shown in the table with pros and cons:
| Screed of bulk floors | Concrete screed | ||
|---|---|---|---|
| Dignity | disadvantages | Dignity | disadvantages |
| The surface is aligned almost independently, there is no need to use beacons. | High cost of materials. | Low value of materials. | The mixture should be aligned on previously installed beacons. |
| When working, the time is reduced to the fill, and the minimum labor costs. | There is no possibility to use the coating re-without restoration. | Great, if you need to align the differences from 2-3 cm and more. | The quality of the surface is lower than that of the bulk screed. |
| After pouring, the solution is obtained very durable. | Flexible material that may be used for a variety of floor covering after laying. Even if on a basis, the tile will lie on, it can be dismantled and laying linoleum or laminate. | The minimum layer is 3 cm. |

For both species, a waterproofing material is used, but the difference lies in the fact that under the sandy cement base you can put waterproofing with waves, and the bulk mixtures are not allowed.
Comparison of materials while working
Big differences cheaper to align cement screed
After preparation, you can start using the selected material, but some questions may arise during the work.
Often, in repairs, builders are a classic screed rush to the large differences, giving the base of the floor with exemplary evenness.
Then the bulk floor is used, which displays the coating in the perfectly smooth plane.
When a liquid screed device does not use the reinforcing grid
For the reliability and strength of the floor, the reinforcing grid is often used. It is used for conventional cement and sand alignment.
As a rule, the grid will be required if laminate or tile will be laid.
If the bulk screed is used, the grid can not be applied, and the strength is achieved due to the thickening of the layers of the mixture.
The bulk floors can be poured without further assistance, although according to the instructions it is recommended to use a roller for moving surfaces.
If the cement floor is planned not to cover the finishing material, you can simply apply several layers of paint on its surface
When the base is completely dry, additional work must be carried out:
- Grinding. It will remove roughness, as well as seal the floor. It is recommended to carry out the grinding procedure 3-4 times for maximum strength. In addition, grinding will improve the adhesion of the concrete base. You can use this method for any floor covering that will be used.
- Cement mortar can be left without flooring. In this case, it is enough to paint the floor for about 5 layers. Of course, for apartments this method is not suitable. It is used more often for basement rooms or garages.
- The most common option for finishing is the laying of waterproofing materials, tiles, laminate or linoleum.
- You can also make a bulk tie of the floor with a pattern or a certain texture.

To say unequivocally, it is better than a screed or bulk sex, it is very difficult. Both materials can complement each other and can be used separately.
The main thing is to determine the ultimate goal of repair and only then select the optimal materials. Works will have to be carried out according to the technology of styling the finishing flooring, so before the filling procedure, it is necessary to study all the features of the materials.

The last thing is to notice - use the bulk of the bulk sex is recommended with a large area of the room. This will significantly reduce labor costs, but for the fill initially it will be necessary to perform a cement-sand tie.
