Why Do Most Table Resins Use Mixing by Weight?

The Importance of Mixing by Weight

Mixing resin and hardener by weight provides far greater accuracy, especially as project size increases. Measuring large amounts by volume can introduce tiny errors, as viscosity and meniscus effects make it hard to get truly precise measurements. By using a set of digital scales, you minimise these risks, resulting in the correct ratio for optimal curing and avoiding issues such as incomplete hardening or tacky surfaces.

Tips for Accurate Measuring and Mixing

• Use electronic scales capable of measuring at least to 1g for large pours.
• Double-check your resin’s recommended mixing ratio—some deep pour resins, such as Epoxytable 10-Ten, require a specific ratio by weight.
• Carefully tare your container before adding each component to prevent miscalculations.
• Always mix thoroughly, scraping sides and bottom of your container, to ensure even chemical reaction throughout the batch.

When This Matters Most

Mixing by weight becomes crucial for deep casting, artistic tabletops, and projects above a few litres in volume. The bigger the batch, the more vital it is to avoid accidental over- or under-dosing of hardener, which can compromise clarity, cure speed, and the structural integrity of your project.
