How to Measure Resin & Hardener Correctly for Ointments

How Should Resin and Hardener Be Measured?

Accurate measuring of resin and hardener is crucial for achieving great results when creating resin ointments. Following the right ratio helps your mixture cure properly, ensuring clarity and the desired finish.

Understanding Mixing Ratios

Resins are designed to work with a specific ratio of resin to hardener, which varies by product. Some resins require mixing by volume, such as the One-2-One Epoxy Resin, which uses a simple equal parts (1:1) measure. Others, like certain art or casting resins, may specify ratios by weight or different volumes. Always refer to your chosen resin’s instructions before starting.

Best Tools and Technique

Use clean, accurate measuring cups or syringes to ensure precision. Pour the correct amount of each component, then combine and mix thoroughly for a minimum of a few minutes, scraping the sides and bottom as you go. Proper blending ensures the reaction occurs evenly, resulting in a smooth, reliable cure and fewer imperfections in your finished ointment.

When This Matters Most

Precise measurement is especially important when making small batches or detailed ointments, where a slight imbalance can cause soft spots, tackiness, or cloudy results. For beginners, choosing a resin with an easy-to-remember ratio, such as 1:1 by volume, can simplify the process and help reduce errors.
