What is the Mixing Ratio for Deep Pour Epoxy Resin?

Understanding the Correct Mixing Ratio

For deep pour epoxy products such as EpoxyTable 5-Five, the recommended mixing ratio is 100 parts resin to 55 parts hardener by weight. Precise weighing is important: using scales, not measuring jugs, is the best way to achieve reliable results. This ratio allows for thick pours up to 5 cm without excessive heat build-up or compromising clarity.

Mixing Method and Practical Tips

Begin by individually weighing both resin and hardener, then combine them thoroughly in a clean mixing container. Scrape the sides and bottom while stirring until the mixture is fully blended—typically at least 3–5 minutes—for complete integration. Pour slowly to minimise bubbles. Do not alter the ratio, as incorrect quantities can prevent curing and affect the final finish.

• Use clean, dry tools for each batch
• Work at room temperature for even curing
• Avoid mixing more product than you can handle within the working time

When Should You Use Deep Pour Resin?

This mixing ratio applies to specialised deep pour epoxies designed for projects like river tables, encapsulating objects, or casting thick decorative layers. Products such as EpoxyTable 5-Five are formulated to allow pours up to 5 cm in a single go. For smaller casts or layers under 2 cm, opt for multipurpose resins like “Trasparente” or “Icrystal” that have their own mixing guidelines suitable for finer work.
