FlowStone produces accurate, bubble-free bases without vibration, making it ideal for use with base formers. Its extended working time allows the pouring of multiple bases with one mix. The dense surface resists dowel pin abrasion and the low setting expansion of FlowStone produces a dimensionally stable base for master models.
Available in white, buff, blue, light blue and light green to provide excellent contrast to die stones.
