What Happens If I Use the Wrong Ratio of Resin to Catalyst?

Common Issues Caused by Incorrect Mixing

If the catalyst is not measured accurately, the resin may not cure as intended. Too little catalyst leaves your resin tacky, soft, or even partially liquid. Excess catalyst can cause rapid hardening with brittleness or uneven finishes, and may introduce surface imperfections. In every case, the end result will lack the reliable strength and appearance expected from a correctly cured resin piece.

How to Measure Resin and Catalyst Accurately

Always follow the manufacturer’s suggested ratios and use dedicated mixing tools for precision. For instance, the ICreation Fast Epoxy Resin uses a simple 2:1 ratio, making it easier to get right every time. Take care to measure both components by weight or volume as directed—eye-balling measurements can easily introduce errors. Attention at this stage saves disappointment later!

When Getting the Ratio Right Matters Most

• Detailed jewellery making, where a flawless, glassy finish is critical
• Art and casting projects needing long-term clarity and strength
• Functional items where durability and a proper cure are truly important

Choosing a resin designed for easy, reliable mixing—such as Liquidissima for jewellery—can help, especially when precision really counts.
