How To Mold & Cast An Alligator Snapping Turtle

Accelerate Mold Max® 30 with Fast Cat® 30. Apply rubber in 3 layers to the bottom and all undercuts and then repeat the 3-coat process on the topside. Fill all cracks and depressions completely. You can use light air pressure to blow silicone into all the detail. To add thickness to the mold use THI-VEX® thixotropic additive to thicken rubber.

Create an open mouth insert and apply a release agent to the inside of the mouth and all the surrounding silicone. Then fill the mouth about half way with thickened rubber. Insert a wooden peg and hold until rubber partially sets.

After the rubber partially sets, fill the remaining void in the mouth with more accelerated rubber, overlapping the edges around lip line.
