Half -dry floor screed is a modern and popular method of aligning the bases for laying flooring. Unlike traditional ways, Half -smoked screed provides rapid drying and high strength, What makes her a preferred choice for many builders and homeowners. In this article, we will consider, What is a half -smoked screed, its advantages, laying process, as well as features and recommendations of production Semi -dry turning floor screed.
What is a half -bomb floor screed
Half-dry floor screed is a type of cement-sand screed, in which the minimum amount of water is added. This method allows you to achieve rapid drying and high screed density, What is its main advantage. The composition of the mixture includes cement, sand and water in the ratio, allows you to get a dense and small mass. To increase strength and plasticity, fiber -fiber and plasticizers can be added.
Advantages of a half -dry floor screed
Half -dry floor screed has a number of significant advantages compared to traditional methods:
- quick drying: Due to the minimum amount of water in the mixture, The half -dry screed quickly dries, which allows you to start further work after 24–48 hours after laying.
- High strength and durability: Half -smoked screed forms a dense and durable surface, which is resistant to mechanical influences and is not subject to cracking. This makes it the perfect basis for various flooring.
- A flat surface: Half -smoked screed allows you to achieve the perfect evenness of the base, which simplifies the laying of finish coatings, such as laminate, tile, Parquet or carpet.
- Minimum shrinkage: Due to the small amount of water in the mixture of the screed of the screed, there is practically no, which prevents the appearance of cracks and deformations.
- Improved heat- And sound insulation: Half -smoked screed provides good heat- and sound, which is especially important when installing floors in residential premises.
- Ease of use: The process of laying a half -dry screed is more convenient and requires less labor cost, since the mixture is easily laid and lends.
Paul -fed -fed technology
The process of laying a half -dry floor screed includes several stages, each of which requires careful observance of technology:
- Substrate preparation: ground, to which the screed will be laid, must be cleaned of garbage, dust and remnants of the old coating. If necessary, the surface is primed to improve adhesion.
- installation beacons: Lighthouses are installed on the basis for monitoring the level of screed. Typically, metal profiles are used for these purposes, which are fixed on the solution or using special mounts.
- mixture: The mixture for a semi -dry screed is prepared from cement, sand and minimum water. The optimal ratio of components - 1 part of the cement for 3-4 parts of sand. It is important to achieve such a consistency of the mixture, in which it will be wet, But not liquid.
- The laying of the screed: The prepared mixture is laid on the prepared base and leveled according to the lighthouses using the rule or a special rail. The half -dry mixture allows you to form a dense and even surface without unnecessary efforts.
- Seal and grout: After laying, the mixture is compacted using a vibration plate or a grout machine. This provides additional strength and density of the screed. Then the surface is wiped, to achieve a perfectly even layer.
- Drying and care: Half -smoked screed requires a minimum time to dry, But in the first few days it is recommended to moisturize the surface to prevent too fast drying and the appearance of cracks. After 24–48 hours, you can start laying the finish coating.
Features and recommendations
Half -dry floor screed - universal method, which is suitable for various types of premises and bases. However, to achieve the best result, it is important to consider the following features and recommendations.
The optimum temperature for laying a half -dry screed is from +5 to +25 °C. At low temperatures, the drying process can slow down, and with high ones - the risk of rapid evaporation of moisture and cracking arises.
The recommended thickness of a half -dry screed - from 40 to 80 mm. When laying on the floors with heated, the thickness of the screed should be at least 50 mm for uniform heat distribution.
Adding fibrum to the mixture improves the strength characteristics of the screed, reduces the risk of cracking and increases durability.
Before laying the screed on the basis of high humidity (eg, in basement or basement) It is recommended to waterproof to prevent moisture penetration into the screed. The control level control of the beacons should be carried out at all stages of laying, to avoid height drops and ensure the smoothness of the surface
If the screed is laid on a large area, shrinkage seams should be provided, which prevent the formation of cracks during temperature and moist fluctuations.
Protection against drafts: In the process of drying the half -dry screed, it is important to protect the room from drafts, to prevent uneven drying and the appearance of defects on the surface.
conclusion
Half -dry floor screed is an effective and reliable method for creating a strong and even base for various types of flooring. Its advantages, such as quick drying, high strength and minimum shrinkage, make this method in demand in modern construction projects. Compliance with the styling technology and accounting for all the features of the material will allow you to achieve a durable and high -quality result, which will last for many years.
This method is suitable for use in residential, commercial and industrial premises, providing comfortable conditions for further operation. If you are planning repairs or construction, The half -dry floor screed will be a great choice for creating a reliable basis of your interior.
