Easy 3:2 Mixing Ratio for Epoxy Resin

What Does a 3:2 Mixing Ratio Mean?

A 3:2 mixing ratio means three parts resin to two parts hardener by weight. For example, if you use 150g of resin, you would add 100g of hardener. Accurate measurement is vital, as an incorrect ratio may lead to a tacky or brittle finish.

• Weigh both components with a digital scale for precision.
• Always follow product instructions specific to your chosen resin.
• Use separate, clean containers and pouring tools to avoid contamination.

Proper Mixing for Best Results

After weighing, blend the resin and hardener thoroughly but gently—mix slowly in a circular motion, scraping the sides and bottom for at least two minutes. This helps minimise bubbles and ensures the hardener is evenly distributed for reliable curing.

Once mixed, use the resin swiftly—pot life is limited, especially in larger volumes or warmer conditions.

When This Matters Most

The 3:2 mixing ratio is especially important for products like the Art Pro clear epoxy resin, widely used by artists and crafters who need a consistent, scratch-resistant finish on decorative items, trays, and coasters. The right ratio ensures your coating is crystal clear and long-lasting.
