FlowStone FS is a revolutionary ISO Type 4 gypsum base stone that sets 50% faster than typical stone products, with early high strength allowing separation from base molds in just 15 minutes. This low-expansion formulation (0.08% setting expansion) produces dimensionally stable bases for master models with a dense surface that resists dowel pin abrasion. With a quick 8-minute setting time and water/powder ratio of 24 mL/100 g, FlowStone FS enables efficient small batch processing of approximately 6 bases per pour while eliminating manual stacking.
