Should Resins Be Mixed by Weight or Volume?

Q: Choosing the Right Method: Weight vs Volume

By Volume: Products like One-2-One require equal amounts of resin and hardener poured into measuring cups, making the process especially user-friendly for crafters and beginners. By Weight: Some resins, such as Art Pro and EpoxyTable 5-Five, need to be weighed with a digital scale because their components have different densities or specific ratios (for example, 100:55 resin to hardener by weight). Carefully follow your resin’s recommended method. Using the wrong approach could lead to soft cures or sticky surfaces.

Should Resins Be Mixed by Weight or Volume?

When working with epoxy resin, it’s important to know whether you should measure your components by weight or by volume. Getting this detail right makes all the difference in how well your resin cures and performs.

Understanding Resin Mixing Ratios

Different resins require different approaches. Many resins, such as those for deep pours or surface coatings, are formulated to be measured using precise weight-based ratios. Other products—for example, One-2-One Epoxy Resin—are specifically made to be mixed in equal parts by volume. The correct ratio will always be indicated in your product’s instructions, so it’s worth reviewing these before you start mixing.

When This Matters Most

The measurement method becomes crucial when swapping between resin brands or project types—such as moving from jewellery work to table casting. Always double-check instructions, as an incorrect mix can ruin your project.
