Clean the surface with rubbing alcohol first to remove any oils. Specifically, polyurethane molds can have problems releasing resin castings. Not even silicone will stick to itself.

Although silicone mold rubber (Mold Max®, OOMOO® and Smooth-Sil®) won't stick to much and has the best release properties of the most common mold making materials used today, it may stick to surfaces with open pores (open grain wood, very dry plaster, concrete, etc. Here we try to explain some fundamentals that need to be understood if you need silicone to stick to another substrate. We then pour liquid silicone into the form area and the silicone settles into the T-slots thus making a mechanical bond that the silicone can not delaminate from.
