How to Ensure Accurate Epoxy Resin Mixing Ratios

Getting the mixing ratio right is crucial for achieving strong, clear, and professional results with epoxy resin crafts. Whether you’re a beginner or an experienced maker, the correct balance between resin and hardener makes all the difference.

Understanding Mixing Ratios

Epoxy resins are typically provided in two parts: the resin and the hardener. They must be combined accurately to activate the curing process and ensure your finished piece is free from tackiness or softness. Some resins, such as the One-2-One Epoxy Resin, use an easy 1:1 ratio by volume, making preparation straightforward. Others may require weight-based measurements or different proportions, so always check the instructions specific to your product before starting.

Tips for Precise Measuring and Mixing

Use appropriate tools: For volume-based resins, use marked measuring cups; for weight-based resins, use a reliable digital scale.
Measure each part separately to avoid accidental overpouring.
After combining, mix slowly and thoroughly for several minutes, scraping the sides and base of the container to ensure all material is blended uniformly.
Work in a dust-free, well-ventilated area to reduce the risk of contamination.

When Accuracy Matters Most

If your project requires a crystal-clear, hard, and glossy finish—such as in jewellery making or fine art pieces—precise mixing is essential. Inaccurate ratios often lead to sticky, cloudy, or weak results that may not withstand use or handling.
