Selecting the right mixing ratio is crucial for a successful epoxy resin project. Using the correct proportions helps ensure a proper cure, clarity, and durability for jewellery, art, or homeware.
Why Mixing Ratios Matter
Epoxy resin relies on a precise balance between resin and hardener. This chemical reaction creates a strong, stable material. If the proportions are off—even slightly—your final result may be sticky, soft, or never fully cure. Ratios vary, so it’s essential to check your product’s instructions before starting.
How to Find and Measure the Right Ratio
Resin manufacturers always state the exact required ratio, either by volume (such as 1:1, equal parts) or by weight (like 2:1 or 3:2). Read the label carefully—the most common DIY options such as One-2-One Epoxy Resin use a 1:1 ratio by volume. For other types like ‘ICreation’, a 2:1 ratio may be required by weight. Always use accurate measuring cups or digital scales depending on the method. Never guess or estimate; a small error can have significant effects.
When This Matters Most
- When using a new type or brand of epoxy resin.
- For detailed projects like small jewellery moulds or deep-pour tables.
- If your work environment is particularly warm or cool, as temperature can affect curing.
