← Back to How do you work with E30 resin?


Getting the right resin-to-hardener ratio is essential for professional-quality results with E30 and other epoxy systems. Even a small error can affect your project’s appearance or durability, so mastering precise measuring is a must for both beginners and experienced makers.
Why Precision Matters
Epoxy resin cures through a chemical reaction between resin and hardener. If the proportions are off, the result may be sticky, cloudy, or brittle. Too little hardener usually leaves the surface tacky, while excess hardener can create unwanted brittleness or discolouration. Always use the mixing ratio specified by your product—for example, products like “Epoxytable 10-Ten” require exact amounts to ensure a strong, clear finish.


How to Measure Accurately
Always measure resin and hardener by weight using digital scales, as volumes can vary with temperature and viscosity. Place your mixing container on the scales, tare to zero, and pour each component separately. Double-check the required ratio (such as 3:2 for some artist resins) in your product instructions before starting. Take your time to avoid accidental over-pouring, as correcting mistakes later is difficult.
Practical Tips for Flawless Mixing
- Work at room temperature to help components combine smoothly.
- Mix slowly for several minutes, scraping the sides and base of your mixing pot.
- If your project requires multiple pours (such as deep castings with Epoxytable 10-Ten), measure each batch fresh—never estimate.
- Dispose of unset resin responsibly and never pour excess hardener into mixed batches.

When This Matters Most
Projects like river tables, thick clear castings, and memorial objects depend on accurate measuring for clarity and strength. For intricate or large projects, even small deviations can lead to costly or irreversible results, making careful mixing even more critical.
