Bake 'dry' ultracal 30 life casts and molds prior to foam latex?
Hello, I was wondering if I need to bake my ultracal lifecast and mold prior to running foam latex? I recently found an online fx book that suggested that plaster pieces, including those made with ultracal 30, retain some water until the water is 'baked out', so to speak, and that if the moisture is not dealt with prior to running foam latex it can steam the foam during the cure and ruin it. Is this true? If so any general guidelines on how long I need to bake my pieces? Thanks in advance! Caterina
