Dry mix based on special cement and expanded polystyrene granules as aggregate.
The product is produced with constant internal and independent (GOST R certification) control.
Application area
It is used as an alternative to dry filling when leveling the surface of the bearing floor and in the presence of a large number of laid cables, pipelines, etc. on it.
Lightweight cement screed KNAUF-Ubo has high thermal insulation properties.
Can be applied by hand or with continuous high performance mortar mixing pumps
After hardening and drying, the surface of the Knauf-Ubo screed must be covered with a hard coating, for example, Knauf dry prefabricated floors made of gypsum-fiber sheets, or high-strength screeds with a thickness of at least 35 mm.
For interior work.
Terms of work
The temperature of the surface of the base and the air in the room must be at least +5°C. Elevated temperatures accelerate the hardening of Knauf Ubo mortars, while low temperatures, on the contrary, slow it down. Base surface preparation The base surface must be dry, sound, free of dirt, dust, paint and oil stains. In the presence of capillary rise of moisture, a layer of waterproofing should be arranged. Moisture-absorbing substrates should be primed with Knauf Tiefengrund primer. If it is not possible to lay directly on the substrate, Knauf Ubo can be laid on a separating layer of waxed Knauf backing paper. In places where the Knauf Ubo screed adjoins walls made of hygroscopic materials (brick, plasterboard sheathing, etc.), their surface should be primed or a separating tape should be used.

Solution preparation
Mix the dry mixture with water, mechanically or manually, in the ratio of 25 kg of the mixture (bag) - 9 liters of water. The addition of any other components is not allowed. When using mixing pumps, for example, PFT or similar mechanisms, adjust the consistency of the solution by changing the water flow.
Application
Apply the mortar manually or with a mixing pump evenly on the substrate until the required level is reached and level with a rule. Fresh screed must be protected from sun exposure and drafts. Rapid drying, especially at high temperatures, may cause cracks in Knauf Ubo, but these do not reduce the performance of the leveling screed.
When the pump is stopped, hoses and instruments must be flushed within 30 minutes.
Storage
Knauf Ubo dry mix bags should be stored in dry rooms on wooden pallets. Pour the material from damaged bags into whole ones and use them first.
Shelf life in undamaged packaging is 6 months.

Modern manufacturers seriously took up the production of screeds different type. If earlier people at the word screed recalled ordinary cement mortars with the addition of sand, now the screed can be mixed from any components and right in a bucket of water.
It is quite obvious that working on this system is several times easier and faster. Not to mention the improvement in the quality of the final product.
Features and characteristics of the mixture
Knauf Ubo is a dry mix from a world famous manufacturer. Use the mixture in order to fill the screed in the premises. It is very easy to notice the differences between this mixture and the usual screed. It is not for nothing that they write on the packaging that the mixture forms a light-type screed.
The fact is that polystyrene balls are added as a filler to the Knauf Ubo mixture. The resulting material almost completely copies polystyrene concrete in its properties.
The advantages of polystyrene-filled ties are obvious. They are lighter in weight than standard solutions. This is due to the use of a special filler. Moreover, the weight of the structure does not affect the density of the mixture. It remains at the level of 600 kg/m 3 , which is an excellent indicator.
Improved thermal insulation properties also cannot be ignored. It is because of them that polystyrene concrete and mixtures using similar technologies are so valued.
Knauf Ubo lays down easily on the floor (including the floor for the garage), and the good adhesion of the composition only contributes to this. A screed from this mixture is never used as a front layer. For this, it is too soft and light. It can only be used as a base.
Moreover, the base can be from 30 to 300 mm thick, which can also be called a positive factor. On top of the screed, it is imperative to lay a layer of several centimeters of a more durable base or front cover. Ceramic tiles are perfect for it.
There are plenty of pros and cons for Knauf Ubo. The mixture cannot be called completely universal, but it has good performance in its class.
Main advantages:
- Low solution weight even;
- Excellent thermal insulation characteristics;
- Small consumption of material;
- Easy and simple process of working with a screed;
- The ability to apply the solution by any means and methods;
- You can buy Knauf Ubo at the best price.
The main disadvantage is too low strength, which leads to the need to lay a solid base on top of the screed.
Before you buy Knauf Ubo, you should decide on your desires. The relatively low stability of the screed affects the possible ways of its application.
The mixture shows itself perfectly when working with attic floors. The fact is that attic floor, as a rule, was not planned in advance and by and large refers to extensions. Ceilings and load-bearing walls in such a situation were not calculated for additional load.
Of course, they have a certain margin of safety, but it is unlikely to be enough to withstand a full-fledged floor made of heavy materials.
In such a situation, choosing a light screed is the right decision. It will not only become a reliable foundation for the front floor, but also improve the thermal insulation of the premises.
Anyway, buy a screed in cases where you need to insulate floors at the construction stage. You can do this with the help of mineral wool or polystyrene, but with Knauf Ubo you will save time and money.
The solution is also well suited for insulating or processing attics. In basements, Knauf Ubo can only be laid after high-quality waterproofing of the floor.
The screed is light and fairly cheap, which allows it to be used in residential areas. Just be aware of its relatively low resistance to point loads and the need to lay a reliable coating.
The mixture is sold in bags with a capacity of 25 kg. The price of Knauf Ubo in a bag is 6-8 dollars. Accordingly, for 1 kg of the mixture you pay only 0.3 dollars, which is almost a record figure.
The material consumption is 7 kg per 1 m 2 with a layer 15 mm thick. The minimum screed thickness is 30 mm. Therefore, the price of Knauf Ubo for 1 m 2 will start at $ 3. Given the lack of need for additional floor insulation, the cost of a screed device will seem quite acceptable to you.
The use of material and the nuances of work
- It has already been mentioned above that the Knauf Ubo screed has a minimum thickness of 30 mm. It is impossible to fall below this indicator, which is very important.
- It is also necessary to knead the screed with great care. It is necessary to knead it so that all the polystyrene balls are evenly distributed throughout the solution. Their accumulation at one point is unacceptable.
- Work is carried out only at positive temperatures. The higher the air temperature, the faster the screed will harden.
- The work surface must be thoroughly cleaned and prepared. The use of a primer is optional, unlike waterproofing. The solution in a frozen form reacts negatively to an excess amount of moisture, so the base should be insulated with high quality.
- One full bag of the mixture is 9-10 liters of water. The screed is kneaded mechanically for 10-20 minutes. Do not add any plasticizers and additional substances to the solution.
The screed is applied manually or mechanically and leveled with a rule. Here the process is no different from the usual filling of the floor with a screed. The solution dries and gains the required density in 48 hours.
Extreme heat will dry the screed much faster and may cause small cracks, but don't worry. These cracks do not affect the characteristics and the possibility of using the finished base.
Light cement screed Knauf Ubo / Knauf Ubo
Sometimes repairing floors requires leveling them, but underground communications, power supply networks greatly complicate the task. Traditionally, in such cases, various dry backfill was used, but today professionals advise buying a dry Knauf floor screed - one of the achievements of modern building technology. Moreover, the Knauf screed at a price of about 300-400 rubles is available for sale on the Internet.
Dry floor screed Knauf Ubo (KNAUF Ubo) is a mixture that contains a special type of cement and expanded polystyrene granules used as aggregate.
Application of dry screed KNAUF
The scope of the Knauf floor screed concerns the repair of floor coverings, namely, the procedure for leveling the floor surface. The light Knauf screed also provides leveling of the floor with a large number of engineering networks laid in it, and is a direct replacement for dry backfill. The screed involves the installation of self-leveling floors or gypsum fiber floors, as well as high-strength screeds with a thickness of more than 35 millimeters.
Knauf Ubo is used for the repair of load-bearing floors only indoors. Distinctive feature and the advantage of Knauf screed is its thermal insulation properties.
Instructions for use KNAUF Ubo
First of all, the area for applying the KNAUF screed must be prepared: the floor coverings must be cleaned of debris and foreign objects, paint or oil stains, and completely dried. If condensation is observed on the surface, it is necessary to provide a waterproofing layer.
Then the water-based screed is kneaded - manually or with the help of mechanized equipment- in the ratio of one bag of 25 kg per 9 liters of water. When using a dry KNAUF screed, it is recommended to buy a mortar mixing pump - for example, PFT brand. Adding other impurities or liquids to the batch is not allowed. The result should be a plastic solution.
Next, the Ubo Knauf screed is applied directly to the floors - again, manually or with the help of a special pump - and the rule is leveled to a single level over the entire floor area. When drying, the UboKnauf screed requires special temperature regime: not lower than 5 degrees Celsius above zero. In addition, high temperatures are also contraindicated for a drying screed, so it is necessary to prevent direct sunlight and drafts on the screed. High air temperatures lead to the formation of cracks on the surface, which, however, do not reduce the quality of the leveling coating.
Benefits and main performance characteristics screeds dry Knauf
In addition to thermal insulation qualities, Knauf Ubo's lightweight cement screed boasts its weight, which is its most important advantage over traditional materials, since excessive pressure on communications under the floor is eliminated. The buyer will also be pleased with the cost-effectiveness of the screed consumption: with a layer of 1 millimeter, about 0.7 kilograms are consumed per square meter. As a result, when using Knauf Ubo, the purchase price will surprise you with its democratic nature.
The Knauf Ubo mix can be bought in 25 kg bags. Knauf dry floor screed is applied in a layer of 3 to 30 millimeters - the thickness of the layer depends on the need, the complexity of the overlap and the degree of its unevenness. At the same time, the maximum thick layer of the screed dries for two days. The consumption of Knauf Ubo is about 7-7.5 kilograms per square meter. meter with a layer thickness of 10 millimeters.
