How to Measure Two-Component Epoxy Resin Accurately

Why Accurate Measurement Matters

Epoxy resin cures properly only when the resin and hardener components are combined in precise proportions specified by the manufacturer. Too much or too little of either can cause curing problems—leading to tacky finishes, weak bonds or incomplete hardening. It’s crucial to check whether your product specifies a ratio by weight or by volume, as using the wrong method could affect your project.

• For many adhesives such as “FixExpress” epoxy glue, a 1:1 ratio by weight or volume is standard.
• Handcraft resins, like the “One-2-One” resin, use an equal 1:1 mix by volume, simplifying preparation.
• Larger furniture kits may have their own recommended ratios—always consult your instructions.

Step-by-Step Guide to Measuring

Begin by reading your epoxy’s instructions thoroughly. Here’s how you can measure accurately for most two-component epoxies:

• Choose the right tools: Use digital scales for weight-based ratios or marked measuring cups for volume-based mixes.
• Work on a flat surface: Ensures correct readings and avoids spillage.
• Pour slowly: Measure Component A, then add exactly the same amount of Component B (1:1 if specified), adjusting with a pipette or syringe for small jobs if needed.

For products with double-chamber syringes, such as “Klebfix” glue, the dosing mechanism automatically dispenses equal quantities—no manual measurement required.

When This Matters Most

Accurate measuring is especially critical for projects where strength, clarity, or cosmetic finish are important—such as jewellery making, furniture casting, or repairing high-stress items. Rushing the mixing step or guessing the ratio can lead to irreversible faults, so take your time when precision is required.
