Using 3 kg of Cores resin for creative projects such as memory boxes or large crafts can seem daunting for a beginner. Following some key tips will help you achieve clear, professional results while avoiding common pitfalls like bubbles and overheating.
Mixing and Pouring: Keep Bubbles at Bay
Always combine the resin and hardener according to the specified ratio, mixing slowly and steadily to minimise air entrapment. Use a wide stirrer and scrape the sides and bottom of your mixing vessel. For deeper pours, it’s best to mix smaller batches and pour in stages rather than all at once. Once poured, gently run a heat gun or torch over the surface for a few seconds to help any trapped bubbles rise and pop.
- Mix slowly to avoid whipping in air
- Pour into moulds or onto surfaces soon after mixing
- Use protective gloves to avoid skin contact
How to Prevent Overheating
Epoxy resins naturally produce heat during curing, and large batches increase this effect. To prevent overheating, pour resin in layers that suit the recommended thickness for your product—generally no more than 2–5 cm at a time, according to the resin’s guidelines. If working in a warm environment, take extra care to keep each pour underneath the maximum advised thickness. Allow each layer to cool completely before applying the next to avoid excessive heat buildup in your project.
When This Matters: Large or Deep Resin Projects
These precautions are particularly important for projects using substantial resin volumes, such as keepsake boxes, tabletops, or poured artworks. If you’re working with a kit like the Resin Memory Box Complete Epoxy Resin Kit with Silicone Moulds – 3kg, careful mixing and controlled layering will deliver the best clarity and structural quality.
