Why is mixing ratio important for epoxy tables?

← Back to How to cast your dream table with epoxy resin

Getting the mixing ratio right is a crucial step when creating an epoxy resin table. It ensures your table is not only beautiful but also strong, clear, and durable for years to come.

The science behind epoxy mixing ratios

Epoxy resin is made by combining two parts: the resin and the hardener. These need to be measured and mixed following the precise ratio provided by the manufacturer, often by weight. This chemical balance is what allows the epoxy to cure properly, delivering a stable and glassy finish.

Too much hardener may result in a brittle or cloudy surface.
Too little hardener can stop the resin from curing, leaving it sticky or soft.
Following the correct ratio supports optimal clarity, hardness, and resistance to yellowing or scratching.

How to achieve perfect consistency

Always use accurate digital scales to weigh your components, avoiding rough estimates by volume. Pouring and mixing slowly, while scraping the sides and bottom of your mixing pot, helps prevent streaks or unmixed resin. Trusted products like EpoxyTable 5-Five and “Epoxytable 10-Ten” clearly label their ideal mixing ratios and provide comprehensive instructions.

When is ratio accuracy most critical?

Sticking to the recommended mixing ratio is especially important for deep pours and larger castings—such as when pouring resin into a thick tabletop mould. Even a small error can affect curing across the entire project, leading to soft patches, discolouration, or cracks after demoulding. For beginners, using a starter kit like the “River-Table” kit can simplify this process by providing pre-measured components and step-by-step guidance.
