How to Follow Correct Mixing Ratios for Epoxy Resin Projects

← Back to How to build a nightstand with decoration and epoxy resin?

Getting the mixing ratio right is crucial when working with epoxy resin, especially for projects such as nightstands with decorative or artistic finishes. It determines the durability, clarity, and performance of your final result.

Why Mixing Ratios Matter

Epoxy resin is typically made up of two components—Resin (A) and Hardener (B)—that chemically react to form a strong, clear material. Using the correct ratio ensures the resin cures properly, achieving a solid and long-lasting surface. An incorrect mix can lead to a sticky, brittle, or cloudy finish that is difficult to repair.

Follow the manufacturer’s instructions for each product. For example, EpoxyTable 5-Five requires a 100:55 weight ratio of Resin A to Hardener B.
Never estimate by eye—always use precise digital scales for accuracy.

Tips for Perfect Mixing

Always measure both components by weight, unless otherwise specified. Pour the hardener into the resin slowly, stirring the mix for three to five minutes with a clean, flat spatula or stick. Scrape the sides and bottom of your container to avoid unmixed material, which could cause curing issues. If recommended, transfer the mixture to a fresh container and stir again before pouring.

When Getting the Ratio Right Really Matters

Mixing ratios are especially important for deep pours, such as creating thick tabletops or decorative nightstand panels. An incorrect ratio when pouring layers up to 5cm thick can compromise clarity and durability. This is vital for furniture that will see regular use, where surface integrity is key to both appearance and longevity.
