What is the Best Mixing Ratio for Clear Resin Projects?

← Back to How to Make Clear Resin

Getting the correct mixing ratio is crucial for successful clear resin projects. The right balance of resin and hardener ensures a strong, transparent finish for everything from jewellery making to table casting.

Typical Mixing Ratios for Clear Resin

Most clear epoxy resins are formulated with a 2:1 resin-to-hardener ratio by volume, which means two parts resin combined with one part hardener. This ratio is common for products like Icrystal – Clear Epoxy Resin. However, always refer to your product’s technical instructions, as some formulas, especially for deeper pours, may call for different ratios such as 1:1 or 3:1. Using the wrong proportions can lead to improper curing or a cloudy finish.

Practical Tips for Accurate Mixing

• Use suitable measuring jugs: Measure resin and hardener by volume, not weight, unless the instructions specify otherwise.
• Mix thoroughly: Stir slowly for at least 3–5 minutes, scraping around the sides and bottom to avoid streaks or soft spots.
• Avoid over-mixing: Vigorous stirring can introduce air bubbles. Mix in a gentle, steady motion for best clarity.

When Mixing Ratios Matter Most

Getting the correct mixing ratio is especially important for clear decorative pieces and thick projects such as resin tables. An incorrect mix can cause tacky finishes or yellowing over time. For layered pours beyond 1.5–2cm, specialist resins and gradual layering are recommended to avoid overheating.
