Mix Your Resin by Weight: Getting Resin Projects Right

Why Mix Resin by Weight Instead of Volume?

Epoxy systems require precise ratios of resin to hardener. While measuring by volume can introduce errors—especially due to differences in density—using weight delivers consistent blends and reliable curing. Even slight miscalculations can cause soft spots or incomplete hardening, spoiling your table’s finish.

Practical Steps: How to Mix by Weight

• Check manufacturer instructions: Always follow the ratio recommended on your resin’s packaging. Most products, like those found in the “River-Table” complete kit, supply specific weight-based guidelines.
• Use digital scales: Select a scale accurate to at least 1g for small projects and 5g for larger pours.
• Weigh resin first: Place your mixing jug on the scale, tare to zero, and pour in the required resin weight.
• Add hardener: Reset the scale, then add the hardener according to the stated ratio.
• Mix thoroughly: Stir well, scraping sides and bottom, until the liquid is completely uniform.

When Mixing by Weight Matters Most

Precise mixing is especially crucial for deep pour applications or projects requiring a flawless, bubble-free surface. For beginners, careful weighing maximises the chances of a successful first project and reduces risk of wasted materials.
