Plaster dry mixes are used for decorative and repair work. Among the rich diversity represented by the Russian market of building materials, the leading position is occupied by the German brand Knauf. The popular brand offers a wide selection of dry mixes, characterized by excellent performance.

Plaster from a well-known European manufacturer is used to decorate horizontal and vertical surfaces. Works are carried out both outside and indoors. Some compositions can be used in locations with high humidity, for example, in storerooms, basements, bathrooms and combined bathrooms. The multi-faceted choice provides customers with a wide range of product uses.

For carrying out facing works outside buildings, experts recommend using gypsum plaster from a German brand. This component significantly reduces the absorption coefficient of water due to the absorption of moisture. Depending on the composition of the mixture, the consumption per 1 m2 (1 m3) and the technology of application varies.

The products of the Knauf trademark are used for facing works at various objects, be it warehouses, residential buildings, government institutions or public institutions, etc.

German plaster mixtures have gained immense popularity and wide distribution due to a number of advantages that are recommended to be familiarized with before purchasing. In drawing up the list, reviews of real buyers and opinions of specialists from the sphere of repair, construction and decoration were used.

Let's start with the pros.

Products do not emit harmful substances.It can be safely used in homes where small children, allergies and pets live.
• The speed of work. If you need to finish the repair as soon as possible, be sure to pay attention to dry mixes from a popular German brand. After their application, you can carry out installation of the floor covering after 3-5 days. This period depends on the indoor microclimate. Full hardening of the layer occurs after 7 days.

• Fireproof. Such a characteristic as fire safety is very important, regardless of the type of building. Increased resistance to fire fully complies with fire safety requirements. Resistance to fire - an indispensable component for a comfortable stay without unnecessary excitement.
• Texture. German-made plaster boasts excellent quality plastered surface. Using products, you can arrange a perfectly smooth and even surface, provided that all rules for the dilution of the composition and its application, as well as operation, will be fully observed.Due to this characteristic, there is no need for further processing of the substrate with the help of leveling or grinding.
