Patience is key to achieving a professional finish when making a resin watch. Knowing exactly how long to wait before demoulding helps prevent flaws and damage to your handcrafted piece.
Typical demoulding times: UV vs. epoxy resin
The time you’ll need to wait before removing your resin watch from its mould largely depends on the resin type:
- UV resin: Cures in as little as 2–3 minutes under a UV lamp. When fully hardened, your piece is ready for immediate demoulding.
- Epoxy resin: Usually requires between 6 and 24 hours to set. For example, with ICreation Fast Epoxy Resin, you can demould after approximately 6 hours, but always allow for a full cure period of 12–24 hours if the piece needs extra strength or a flawless finish.
Practical tips to achieve clean demoulding
To make demoulding straightforward and prevent sticking or surface flaws, ensure your silicone mould is clean and dry before pouring. If using epoxy, wait until the piece feels firm to the touch and non-tacky before attempting removal. Use gentle pressure around the edges to ease the watch out without flexing or forcing the mould. For intricate details, select a resin kit with enhanced degassing properties or consider using a starter kit like the Evershine Collection for consistent results.
When this matters: Avoiding imperfections and wasted effort
Demoulding too early can lead to bends, surface marks, or sticky patches on your resin watch—undoing hours of creative effort. If you are unsure, it’s best to err on the side of caution and leave your piece for the maximum recommended curing time. This is especially important on humid days or for thicker layers, which may take slightly longer to harden through.
