In & Out™ II and AquaCon™ by Smooth-On are high-performance release agents for concrete and gypsum castings. They facilitate demolding, preserve fine surface details and support clean, repeatable results.
In & Out™ II: A water-soluble release agent for casting concrete and gypsum in rubber molds. It enables clean demolding without loss of detail and helps reduce trapped air and surface imperfections.
AquaCon™: A water-based, VOC-free release agent for concrete castings in rubber and latex molds. It provides reliable release without affecting colour or surface detail and helps reduce air bubbles.
Both products are suitable for artists, mold makers and manufacturers casting concrete or gypsum in silicone, polyurethane or latex molds. They improve surface quality, reduce casting defects and can extend mold life.
