Nassestrich

Nassestrich is a German term referring to a type of concrete screed used in construction, primarily for flooring applications. It is characterized by its wet, fluid consistency during application, which allows it to be poured and spread easily. This semi-liquid state enables it to fill voids, level uneven subfloors, and encapsulate underfloor heating pipes effectively.

The composition of Nassestrich typically includes cement, sand, water, and sometimes admixtures that modify its properties, such as improving flow or accelerating setting time. It is usually applied in a single layer over a substrate like concrete or insulation. Unlike dry screeds, which are composed of granular materials, Nassestrich hardens through a chemical reaction involving water and cement, creating a monolithic, dense surface.

The primary function of Nassestrich is to create a stable, level base for subsequent floor coverings like tiles, parquet, or carpet. Its ability to flow also makes it ideal for creating a homogeneous bond with underfloor heating systems, ensuring efficient heat transfer. Once applied, Nassestrich requires a curing period, during which it hardens and gains strength. The drying time can vary depending on thickness, ambient conditions, and the specific mix used. Proper ventilation and controlled drying are crucial to prevent cracking and ensure the screed achieves its intended performance.
