Epoxy resin: what is the correct mixing ratio?
Understand ratios for flawless resin results every time.
If you want to achieve flawless results with epoxy resin, understanding the correct mixing ratio is a fundamental first step. This page explores the most common ratios, helps you compare popular resins side by side, and guides you in selecting the right product for everything from jewellery making and crafts to rapid projects and impressive deep-pour tables. Whether you are a beginner or a seasoned creator, you’ll find the information you need right here.
How Epoxy Resin Mixing Ratios Differ (and Why It Matters)
Every epoxy resin product requires a specific proportion of resin to hardener to cure correctly. Some resins use an easy 1:1 ratio, while others may need a 2:1 or even 4:1 formula. Getting these measurements right is vital: an incorrect ratio can leave your project sticky, brittle, or uncured. The right choice depends on your project’s type, size, complexity, and time constraints. Below, we highlight the crucial points that set these products apart and when you should choose each ratio.

Tips for Accurate Mixing and Best Results
Regardless of which epoxy resin you choose, always read the instructions on the product label for the correct resin-to-hardener ratio—some are measured by volume, some by weight. Use separate mixing containers for each component before combining, and mix thoroughly but gently to minimise bubbles. For deep pour projects or rapid-cure resins, ensure your workspace is dust-free and work at the recommended temperature. Precision in measurement is your best guarantee for successful curing, crystal clarity, and high durability. If in doubt, start with a small test batch to perfect your process before your main project.

Frequently Asked Questions
What happens if I use the wrong epoxy resin ratio?
Incorrect mixing ratios can cause incomplete curing, sticky surfaces, or brittle finishes. Use measuring tools and follow product instructions closely.
Should epoxy resin be mixed by weight or by volume?
Always check your product label. Some resins are mixed by volume (like 1:1 types), while others require mixing by weight for correct curing.
What’s the easiest mixing ratio for beginners?
A 1:1 ratio by volume is simplest, ideal for crafters and jewellery makers wanting error-free results.
When should I choose a fast-curing epoxy?
Fast-cure epoxy is best for urgent projects or when time is limited. Ensure you can mix and pour quickly to avoid premature setting.
How should I mix epoxy for deep pours like tables?
Use a resin designed for deep pours, usually with a different (often 4:1) ratio. Follow instructions and pour in layers as required.
What can I do if my epoxy stays tacky or cloudy?
Check your ratios and mixing process. If issues persist, remove and remix according to product directions for future attempts.
Can I change the resin ratio for different results?
