What the AI looks for in Sculpture Release Agents

Material pairing
Choose a release for the specific pair (for example silicone on silicone or urethane in silicone) Like materials bond to each other without the right barrier.
Porous masters need sealing first
Seal plaster, wood and unfired clay before applying release Release soaks into porous surfaces and stops protecting the mold.
Paintability
Wash parts or use a paintable release if they will be painted Silicone-based release residue causes paint to bead.
Application
Apply light, even coats and let the carrier evaporate before pouring Pooled release ruins surface detail.
