Liquid screed or self levelling compound?
Liquid flow screed and self levelling compounds are both types of flooring materials used to create a smooth and level surface for the installation of a final floor covering. However, there are some key differences between the two:
Composition: Liquid flow screed is typically made up of cement, sand, and water, along with various additives such as flow agents and accelerators to improve its properties. Self levelling compounds, on the other hand, are usually made from a blend of synthetic resins, such as epoxy or polyurethane, and other additives.
Flow Properties: Liquid flow screed is designed to be self compacting, however, it still requires some manual smoothing and finishing to achieve a fully level surface. Self levelling compounds, as the name suggests, require minimal manual smoothing as they are designed to flow and self level to create a smooth finish.
Drying Time: Liquid flow screed typically takes longer to dry and cure than self levelling compounds. The drying time for liquid flow screed can range from a week to several weeks, whereas self levelling compounds can be ready for the installation of a final floor covering within a matter of hours due to its reduced water content.
Applications: Liquid flow screed is typically used for larger areas such as commercial or industrial floors, while self levelling compounds are more commonly used for smaller areas such as residential floors or for patching and repairing uneven surfaces.
Ultimately, the choice between liquid flow screed and self levelling compounds will depend on the specific requirements of the project, such as the size and complexity of the area, the final floor covering to be installed and the desired finish.
