Do you use a mold release over a sculpt when using Ultra Call 30? I'm working on a pred mask sculpted out of firm klean klay and am wondering if you use a release on the clay sculpt like say petroleum jelly or pam. I've read that these are used on resin reproductions and I was just wondering if the were used to get the sculpt from the mold cleanly as well. Any info is greatly appreciated. Thanks.

I've not heard of anyone needing a mold release on the clay. The stuff I've known people to use is Krylon's Cristal Clear and then Dulling Spray. The dulling spray is said to help the detail coat stick better to the sculpt.

My experience is with Hydrocal and have never sprayed anything on the sculpt itself. The only time I've used a mold release in when doing two piece molds. Petroleum jelly on the contact areas between the halves.

I've used alcohol and a brush to clean any remaining Klean Klay out of the mold that wouldn't come out with a wooden tool.


This is my most recent experience with slightly different techniques on my part:

As far as the resin reproductions, I only use mold release sparingly. I've found that with the detail that slicone copies, the mold release will actually show up in the mold details.

Hope this helps.
