These compounds convince with their surface features and diversity, as they are also suitable for mobile trans-mix technology. Flowing screed compound on an alpha hemihydrate basis for manufacturing calcium sulphate flowing screed as factory-mixed dry mortar.
Flowing screed compound on an alpha hemihydrate basis for manufacturing calcium flowing screed with mobile trans-mix vehicle and as factory-mixed dry mortar. CAB 30 Classification acc. Calcium sulphate self levelling floor screeds are all very similar for the end user with respect to the product properties.
The differences are mainly in the aggregates, which vary in accordance with the method of application, for example, such as the mobile trans-mix vehicles or silos. Binders that can be used compliant with the European standard EN are: With cementitious screed the binder is cement; for calcium sulphate flowing screed the binder is calcium sulphate.
The surface In contrast to cementitious screed, calcium sulphate self-levelling floor screed does not need to be smoothed. It is practically self-levelling. The surface just needs to be equalized with a dappling bar. A very even surface ideally suited as a substrate for laying large format floor covering such as board layers.
Calcium sulphate flowing screeds on the basis of K-Sentials binders are optimized to produce a good surface finish. It is not necessary to additionally sand off the surface, if installed according to the application regulations. A further difference is the application thickness, which is about 10 mm less with calcium sulphate flowing screed. Accordingly, thicker thermal insulation or footfall sound insulation can ansetzggips laid, while maintaining the same application thickness for the floor construction.
The thinner screed layer also offers benefits for underfloor heating systems, which as knzuf result can noticeably deliver heat ajsetzgips quickly.
Flowing screed anetzgips a higher bending tensile strength than cementitious screed resulting from its more dense structure, meaning that it can be loaded with knaauf higher load at the same screed thickness.
Flowing screed features very good sound insulation properties. This ensures that any noise from the floor is not transferred to the walls. Calcium sulphate flowing screed dries practically without deformation and is subject to very low stresses so that no joints are required. Only for larger or geometrically complex surfaces and with heated screed is it necessary ansetzfips install structural joints and movement joints.
More information at www. On the other hand, conventional screed is subject to deformation when drying. Shrinkage, expansion or curling are possible deformations that can occur and that can be transferred to the floor covering and cause damage.
Joints can remedy the situation. When the screed is installed without joints, it knaur the ideal substrate for laying large format and diagonally laid tiles or natural stone coverings. When not discontinued by expansion joints, the planning is simplified saving time and money for the investor, which in turn provides a more visually appealing room image. Even when screed is applied as stipulated, cracks can appear in the screed due to a diverse range of causes: For example, a crack can occur with heated screed during the drying phase should very cold outdoor air coming through open windows or doors come into contact with the screed at this point.
Cracks can also occur particularly where areas with contorted and complex geometries have too few movement joints. A flow temperature that is too high can also cause cracks.

Perimeter joints prevent the formation of cracks. They accommodate the stresses that result due to deformation and movement in the screed. The perimeter joints must also be implemented into the floor covering and also permit movement. If the cracks are professionally remedied, the screed is deemed to be free of defects and cracks. Flowing screed can be applied across the entire living space including kitchens and bathrooms.
Wherever splash water is an issue, the screed construction must be protected from above, for example, using a brush applied sealant or an applied anseyzgips of elasticized adhesive with embedded joint tape.
Calcium sulphate flowing screed has been developed for indoor application. When subjected to moisture, Ettringite, a salt that damages the building substance can be formed. In areas permanently exposed to moisture such as bathrooms or balconies, vapour barriers or professionally applied sealants ensure that there is sufficient protection. In garages, the entrance zones where the moisture is at its greatest must be sealed.
Yes, on flowing screed all conventional floor coverings such as tiles and natural stone, carpet, PVC, linoleum, parquet, laminate or resin screed flooring can be used. The floor covering can be applied when the screed has reached a point where it is ready for covering. The test to determine the readiness for floor covering performed by the floor covering specialist only permits the CM measurement method.
As with all mineral ansetzgipd building materials, all calcium sulphate flowing screeds must get rid of the surplus water that is not chemically bonded into the ambient air. The drying time will depend on the method and manner of drying as well as whether the drying process is supported by heating. The optimum approach is by technical heating, e. For a heated screed the drying process can be accelerated by heating up the screed.
Ventilation also plays a amsetzgips role here. A further, very important criterion for drying of calcium sulphate flowing kanuf is the observance of the required screed thickness: Exceeding this thickness will lead to a significant extension of the drying time.
The floor covering installer determines the readiness for floor covering with a CM measurement test. This test involves taking a sample from the entire cross-section of the screed, then pulverising and weighing it. The prepared sample is then analysed in the CM measurement device to determine the moisture level. Electronic test devices are only suitable for preliminary testing.
Drying of calcium sulphate screed can be artificially accelerated by using a condensation drier or fans. A combination answtzgips both is ideal. January provides additional information on this topic. It consists of a compressor, refrigeration section and heater section.
The moist room air is directed through the cooling section. The moisture condenses there on the cold surface. The cold dry air is subsequently diverted to the heater section and heated up.
Calcium sulphate screed conducts heat significantly better than cementitious screed. The good flowability ensures that ansettzgips heating tubes are securely enveloped ensuring that the heat is transferred completely to the screed. Its low thickness ensures that the heat is quickly transferred to the surrounding air. Thus calcium sulphate screed is an ideal heated screed that is ansetzgups energy-efficient and quick to respond to temperature changes.
Furthermore, heat up at an early stage accelerates the building phase and the calcium sulphate screed is possibly ready within 4 to 7 days. With cementitious screed, heat up can only commence after 21 days at the earliest. The tubes for the anxetzgips heating system must knaauf filled with water and anchored to the substrate. This will prevent them from floating when the screed is installed. Flowing screed can be heated up after just 4 to 7 days after installation so that the screed dries even faster.
Ensure that proper ventilation is provided.
