Fix Sticky or Soft Resin After Casting

Q: How to Fix Incomplete Curing

Leave to Cure Longer: Sometimes, simply allowing your piece more time in a dust-free environment helps it reach full hardness. For UV-curing pieces, place them under a UV lamp again if needed. Check Your Mixing: With two-part resins like those in the Evershine Collection , mix equal parts carefully and scrape the sides and corners during mixing. Apply a Clear Top Coat: If only the surface remains tacky but the inside is cured, a thin layer of fresh resin or a UV top coat can seal the sticky finish.

Q: Prevention Tips for Crisp, Cured Resin Rings

Accurate Measuring: Always follow the correct resin and hardener ratios specific to your resin type. Thorough Mixing: Stir resin slowly and consistently to ensure a uniform blend that cures evenly. Consistent Curing: Use the right UV lamp for UV-based products, or set aside enough time for standard epoxies to set. Fast-curing options like UV–Creation can minimise mistakes due to speed and ease of use.

Encountering a sticky or soft resin ring after casting can be frustrating, especially after investing time in your creative project. Let’s look at why it happens and how you can quickly resolve and prevent the issue for future resin ring making.

Why Resin Rings Stay Sticky or Soft

The most common reason for sticky or soft resin after demoulding is under-curing, which often stems from incorrect mixing or insufficient cure time. For two-part epoxy, not following the correct resin-to-hardener ratio or failing to mix thoroughly can result in a tacky finish. For UV resin, improper or incomplete exposure to UV light sometimes leads to a surface that never fully hardens. Always carefully check your mixing ratios and cure times as indicated on your chosen resin product.

When This Matters Most

Getting your resin to cure properly is especially important when creating wearable jewellery. Rings and other accessories require durability and a smooth, comfortable finish that won’t mark clothing or irritate skin, so always ensure your technique is sound.
