How To Store The Silicone Mold

Molds should be stored in a cool, dry area and out of the sunlight, which can degrade the surface.

Store molds in their original, undistorted shape. Molds should be left in the mother mold, mold box or on a surface that causes the least distortion possible. If rubber is left in a distorted shape for any length of time, it may never recover to its original shape.

If a blanket mold is stored in a mother mold/shell made of porous material, such as bare plaster, the shell surface that contacts the mold must be sealed. Sealing the shell prevents it from absorbing oils from the mold rubber which, in turn, can cause mold distortion.

Do not allow molds made of one type of rubber to remain in contact with molds of other rubbers as migration of oils or plasticizers from one to another can cause swelling, shrinkage, or distortion.
