Sopro FS 15® plus Levelling Compound 2 – 150 mm

Universal, pumpable, self-levelling, rapid-set, cementitious surface filler with excellent flow properties. Applied in thick and thin coats to level out mineral substrates and produce smooth, plane, unbroken subfloor surfaces. Used as a base for all types of floor covering, e.g. ceramic, natural stone, textile, elastic, and parquet flooring. Castor chair resistant and suitable for use in conjunction with floor heating. Excellent workability and hardened mortar properties thanks to Sopro Mikrodur® technology. Excellent flow properties achieved by the use of a superplasticizing admixture.
