Sculpting with Epoxy Putty ‑ Free Form® AIR & SCULPT


A tree and female figure are sculpted using Smooth-On Free Form AIR & SCULPT epoxy putties. Free Form AIR is a lightweight two-part epoxy dough that is useful for making armatures or bulking out areas of a sculpture. Free Form SCULPT is a high-fidelity sculptable epoxy putty that stays malleable for up to five hours after mixing then hardens when left at room temperature.
