Getting the correct resin-to-hardener ratio is key to successful results in resin projects. Here’s what you need to know before using your kitchen or household scales for resin mixing.
Why Accurate Measuring Matters
Mixing resin and hardener needs precision. If measurements are even slightly off, the resin may not cure properly or could end up sticky or brittle. Accurate digital scales help ensure you get exact weights, especially for resins requiring weight-based mixing ratios.
Are Kitchen Scales Good Enough?
Standard household or kitchen scales are designed for cooking and may not be sensitive enough for resin work, particularly with small or detailed projects. Even small errors can throw off the chemical reaction. For most resin types, especially those mixed by weight, use digital scales with at least 1g accuracy—or finer for small batches.
Mixing By Volume or Weight
Some resins—like One-2-One Epoxy—use a 1:1 ratio by volume rather than weight. In these cases, precise measuring cups work well. However, always follow the manufacturer’s instructions for your chosen resin.
When This Matters
Accurate weighing is especially important for transparent projects, jewellery, river tables, and coasters. Inaccurate mixing can spoil the finish or waste costly materials.
