Hello, two or three times now I've used 'Amazing Mold Rubber' to create a mold.
Problem is I cannot make a 2 part mold. I wait 2 or 3 days to make sure the first part is hardened. Then I douse it liberally with "Castin' Craft Mold Release and Conditioner" I let it dry for an hour or so.
When I pour the second half, the two parts always fuse together, creating a solid mass.
Absolute best mold release for releasing silicone to silicone is Vaseline. Whenever I've had problems or was nervous, I simply smear a very thin layer of Vaseline with my finger anywhere the second half will touch the first. I try to avoid touching my master as it can make the master look glossy and the rubber will pick that surface appearance up and reproduce it in your casting.
The Amazing Mold Rubber has such an extremely high tear strength, I've found it sometimes will grab and adhere just enough to fuse two part molds even when doused with a sprayed mold release.
