Cementitious SL Underlayment 2–20 mm | Fast-Setting Self-Levelling Screed

Cementitious SL Underlayment 2–20 mm is a high-performance, cement-based self-levelling compound designed for precise levelling of a wide range of substrates. It is ideal for cement floor screeds and mineral subfloors where a smooth, flat and dimensionally stable surface is required.

This self-levelling screed can be applied in thicknesses from 2 to 20 mm in a single operation, providing excellent flow, minimal shrinkage and high resistance to internal stresses. Its advanced formulation ensures consistent levelling results on both new and existing substrates, even over larger surface areas.

The product combines mineral binder hydration with polymer film formation, resulting in strong mechanical performance, excellent surface integrity and long-term durability. Thanks to its fast-setting properties, the floor becomes walkable after approximately 3 hours, significantly reducing downtime on site and accelerating project timelines.

Cementitious SL Underlayment 2–20 mm is fully pumpable, making it suitable for mechanical application on medium to large projects where speed and uniformity are critical.

This levelling compound creates an ideal substrate for subsequent floor finishes such as ceramic tiles, carpet, parquet flooring and other decorative or functional coverings. It can also serve as a reliable base layer for advanced resin flooring systems, including epoxy and polyurethane self-levelling floors.

By delivering fast curing, excellent levelling accuracy and broad compatibility with common floor finishes, Cementitious SL Underlayment 2–20 mm is a dependable solution for both residential and commercial flooring projects.
