What’s the Difference Between 1:1 and 2:1 Epoxy Resin?
If you’re diving into resin crafts or jewelry making, you’ve likely come across epoxy resin. But not all resins are created equal. One common question is: What’s the difference between 1:1 and 2:1 epoxy resin? Understanding the distinction can help you avoid sticky mistakes and achieve the perfect finish every time.
What Do 1:1 and 2:1 Mean in Resin Mixing?
These numbers refer to how you combine the resin (part A) and the hardener (part B):
- 1:1 epoxy resin = equal parts resin and hardener
- 2:1 epoxy resin = 2 parts resin to 1 part hardener
Measuring correctly is critical—getting the ratio wrong can result in tacky surfaces or incomplete curing, which ruins your flowers or jewelry pieces.
Comparison: Which Resin Type Suits Your Craft Best?
| Feature | 1:1 Epoxy Resin | 2:1 Epoxy Resin |
|---|---|---|
| Mixing Ratio | 1 part resin : 1 part hardener | 2 parts resin : 1 part hardener |
| Best For | Coating pressed flowers, small jewelry molds | Deep flower blocks, large mold pours |
| Viscosity | Thicker—good for staying in place | Thinner—flows better into deep molds |
| Working Time | Shorter (sets quicker) | Longer (more time to adjust flowers) |
| Cure Time | Faster cure | Slower, ideal for complex projects |
| Clarity | Slightly softer finish | Often clearer and more glass-like |
Which One Should You Use for Flower Crafts & Jewelry?
- Use 1:1 resin if you're making:
- Small pendants or rings with dried flowers
- Quick coating projects like bookmarks or coasters
- Projects where time is limited or you're a beginner
- Use 2:1 resin if you're making:
- Larger floral blocks or paperweights
- Jewelry with deep molds that need more pour time
- Pieces where ultra-clear and bubble-free finish is important
Tips for Working with Flowers in Resin
- Always dry your flowers fully before embedding—moisture causes clouding.
- Pour in layers for thicker pieces to reduce bubbles and heat.
- Use a toothpick or tweezers to position petals precisely.
- Torch or heat gun lightly to pop surface bubbles.
Final Thoughts
Whether you're preserving wedding blooms, making botanical jewelry, or creating timeless gifts, understanding resin ratios helps your creativity shine.
1:1 resin offers simplicity and quick results, while 2:1 resin gives you clarity and flexibility for intricate designs. Choose wisely—and let your flowers bloom forever in resin
