How To Make a 2 Part Silicone Mould

This video outlines the 2-part block mould making technique using Mold Star® 15 silicone rubber.

Mold Star® 15 is a platinum silicone that is mixed 1A:1B by volume (no weighing scale necessary).

When making a 2 piece mould, it is important to use the correct release agent to separate the 2 halves.  When pouring silicone rubber, Ease Release 200 is the recommended release agent.

A 2 part mould allows for easier demould than a single piece cut mould or glove mould.  It can also provide superior registration, reducing the amount of casting clean up necessary.
