How To Vent a Silicone Mold to Eliminate Bubbles In Casting

Turn the mold box over to prepare for demolding. Loosen the mold box screws using a drill and remove the baseboard and clay from the perimeter exposing the back of the model. Carefully remove the clay from the holes of the model as well. Next, remove the acorn nuts from the cured silicone. Once all of the clay is removed, clean the model with alcohol and spray Ease Release® 200 release agent onto the model and cured rubber, brushing it over all surfaces.
