Resin Mixing Ratios & Step-by-Step Instructions

What Is a Resin Mixing Ratio?

Each epoxy resin system relies on a specific ratio of resin (part A) to hardener (part B). This determines curing time, clarity, and durability. For example, EpoxyTable 5-Five requires a 100:55 weight ratio (100 parts resin to 55 parts hardener). Other resins, like “Icrystal” and “Trasparente”, may use different ratios, so always refer to the label or supplied instructions for accuracy.

How to Measure and Mix Correctly

• Weigh, don’t guess: Use digital scales for accuracy, measuring both parts by weight, not volume unless directed otherwise.
• Mix thoroughly: Pour the measured amounts into a clean container, then stir slowly for at least 2–3 minutes, scraping the sides and bottom, until the mixture turns completely clear and uniform.
• Avoid shortcuts: Using the wrong ratio or rushing the process can lead to a sticky or cloudy finish, or prevent curing altogether.

Matching Resin Type to Your Project

The ideal mixing ratio varies depending on which resin you need. For example, deep pour projects benefit from EpoxyTable 5-Five’s precise 100:55 mix, while jewellery and shallow crafts are better suited to “Trasparente” or “Icrystal”, each with their own unique ratios. Double-check instructions each time, as different tasks call for dedicated resins with tailored proportions.
