Why Hasn’t My Resin Pendant Cured? Common Causes & Fixes

Q: Practical Solutions and Preventative Steps

Measure accurately: Use digital scales or supplied measuring tools to get perfect ratios, following product advice. The Evershine Collection Kit is especially beginner-friendly with its simple 1:1 mixing resin. Mix thoroughly: Scrape the sides and bottom of your mixing cup for at least 3–4 minutes, even if the solution looks clear earlier. Control the workspace: Make sure your room is warm and dry. Avoid draughts or dampness which can impact curing. Let it rest: Resist the urge to demould early. Some formulas cure in 12 hours, others need a full day or more. Fast-curing resins, like ICreation Epoxy , are available if you need results quickly—demoulding is possible in as little as six hours.

If your resin pendant feels soft, tacky, or simply refuses to set, you are not alone. Understanding why curing fails will save your creations and prevent future headaches.

Understanding Resin Curing Problems

The most frequent cause of an uncured resin pendant is incorrect measurement of resin and hardener. Epoxy products usually require exact ratios—such as a 1:1 or 2:1 mix. Even a small miscalculation can leave your pendant sticky or soft. Thorough mixing is just as important; poorly combined resin, especially around the edges of your mixing container, may remain uncured.

Temperature is another factor. Resin cures best at room temperature (typically 20–25°C). Cooler environments slow or halt the process, while condensation can also interfere with curing. Always check the manufacturer guidelines for ideal working conditions.

When This Matters Most

Curing issues are particularly troublesome if you’re making pendants as gifts, working to a deadline, or embedding delicate materials such as dried flowers. If your pendant contains botanicals, make sure flowers are fully dried, since trapped moisture can inhibit curing or cause cloudiness. Choosing prepped dried flowers for resin casting adds peace of mind and consistent results.
