How To Make a Quick Silicone Wound Prosthetic

Smooth-Cast® 300 will cure in 20 minutes, and then the clay mold wall can be removed. The resin mold can now be removed from the sculpt while capturing excellent detail. Pour a small amount of 99% isopropyl alchol into a cup and use a clean brush to remove the remaining clay out of the resin mold. Sand the edges of the mold until smooth and then the finished flat resin mold is clean and ready for silicone casting.
