Lifecasting silicone hands.

Drewskiman

So I'm using body double standard and mixing in hyperfolic so my models hair won't get pulled out. That part goes extremely well. My problem is, after pulling the mold of my models hand and putting in the release agent (205) and letting it sit for an hour, the mold still sticks to the silicone I pour inside. Am I missing a step?

When casting silicone in a silicone mold a release agent alone is usually not enough.   Often a wax, like Sonite from Smooth-On, or a PVA film is used to act as a barrier, in addition to a release agent.

I tried washing out a new mold with hot water and soap. Was easier to pull out. Still a little difficult but it worked. Thanks for the help! I'll have to look up sonite. Also, can you mixed the sonite with 205?

The page for 205 https://www.smooth-on.com/products/ease-release-205/ does mention it works on wax, so it should be fine with Sonite.  They also mention Ease Release 200 on the Sonite page https://www.smooth-on.com/products/sonite-wax/
