How to Accurately Measure Resin and Hardener for Epoxy

← Back to How do you colour epoxy resin for painting?

Achieving great results in epoxy resin painting starts with measuring your resin and hardener accurately. Correct proportions ensure your artwork sets properly and delivers a brilliant finish.

Understanding Mix Ratios

Epoxy resin products always require a precise mix of resin (Part A) and hardener (Part B). Most kits specify a ratio, often by weight (such as 2:1 or 1:1), which is crucial for successful curing. Mixing the correct proportions prevents problems like tackiness, incomplete curing, or weak results. Before starting, always check your specific product instructions for the recommended ratio.

Tips for Accurate Measuring and Mixing

Use digital kitchen scales to weigh out both components for best accuracy, placing your mixing cup on the scale and taring it before each pour.
Pour resin and hardener slowly to avoid overshooting your measurement, and double-check the numbers.
Mix thoroughly for at least 2–3 minutes, scraping sides and base to ensure even blending—this helps achieve solid, non-sticky results.
Each colourant, such as those from the Colourfun Set, can be added after the initial mixing for vibrant or translucent effects.

When Accurate Measurement Matters Most

Accuracy is especially important when creating functional or high-display pieces, like painted tabletops or resin art panels. Properly measured epoxy not only cures with a flawless finish but also supports the depth and intensity of coloured effects.
