A cement-based grout formulated with ultra-fine, quartz-free fillers and special additives. It is designed to produce fine joint surfaces with high strength, while also offering excellent workability and a long cleaning/washing window. When mixed with water, it forms a smooth, creamy and highly workable mortar with good yield. It is easy to apply, does not burn off prematurely, has excellent filling capacity, and adheres firmly in the joints without cracking. The finished grout surface is very fine and smooth.
