How long before resin, silicone or plaster can be demolded?
Use the milestone for demolding, not a generic dry-to-touch time. The table below is built only from numeric times in manufacturer documents already recorded in our catalog.
Important: Shortest does not mean interchangeable. Product type, surface, conditions and intended use still have to match your project.

- Check temperature, humidity, thickness and substrate notes.
- When the manufacturer provides no correction factor, wait longer and verify physical readiness.
