2:1 Resin to Hardener Mixing Ratio

What Does the 2:1 Ratio Mean?

Mixing at a 2:1 ratio means combining two parts resin with one part hardener by either weight or volume (as specified by the manufacturer). Accurate measurement ensures the mixture cures properly, resulting in a clear and durable finish. Too much hardener or resin risks a tacky, weakened result.

Step-by-Step Mixing Guidance

• Prepare your workspace: Ensure all tools and surfaces are clean and dry.
• Measure carefully: Use dedicated mixing cups or scales to achieve precise 2:1 proportions.
• Combine and mix thoroughly: Pour the resin and hardener together and stir slowly, scraping the sides and bottom, until fully blended and streak-free. This step often takes 3–5 minutes.
• Apply promptly: Once mixed, use the resin straight away for coating, casting, or impregnating fibres (as with “Icrystal” – Clear Epoxy Resin or other recommended products).

When Is the 2:1 Ratio Critical?

This ratio matters most for structural applications such as carbon fibre or fibreglass lamination, woodworking finishes, and artistic projects needing clarity. Sticking to this proportion delivers optimum curing and performance—for both professional and hobby uses.
