Understanding Deep Pour Resin and Casting Resin
Resin crafting is growing fast - from furniture makers to small home artists. But before starting any project, it’s important to understand the difference between deep pour resin and casting resin. The most common questions, the ones that many beginners pose are, what is the difference between art resin and casting, or what resin they should use clear casting resin or should they use deep pour. The finish, strength and clarity of your project are all directly dependent on the material you select whether a Res-iT Epoxy deep pour formula or a standard casting resin.
1. What is Deep Pour Resin?
Deep pour resin is a specially formulated epoxy designed to cure in thick layers, typically from 1 inch (2.5 cm) up to 6 inches or more without overheating.
- Designed for thick, high impact pieces
- Ideal for river tables, countertops, shelves
- Reduced heat build up prevents yellowing or cracking
- Crystal clear finish even in deep layers
Deep pour resin formulas like Res iT Epoxy Deep Pour are meant for large projects where ordinary resin would overheat and fail.
2. What is Casting Resin?
Casting resin is formulated for thin pours and detailed mould work, typically under ¼ inch (6 mm).
- Used for jewellery, coasters, paperweights
- Easy to work with and cures fast
- Comes as a clear casting resin to preserve detail
- Often beginner friendly
Casting resin is great when you want precision and detail - not thickness.
3. Art Resin vs Casting Resin - What's the Difference?
A lot of beginners search art resin vs casting because they seem similar. Here's how they differ:
- Art Resin - Usually a pourable, clear epoxy for flat surfaces (like tabletops and artwork)
- Casting Resin - Made for small moulds (jewellery, figures, coasters)
- Deep Pour Resin - Made for thick layers without cracking or excessive heat
So while art resin can sometimes be used for shallow casting, it's not the same as true casting resin or a deep pour resin.
4. Deep Pour Resin vs Casting Resin - Side by Side Comparison
| Feature | Deep Pour Resin | Casting Resin |
|---|---|---|
| Best for | Thick layers, large pieces | Small moulds, jewellery |
| Heat Build up | Low (designed for deep pours) | Higher if used thick |
| Curing Time | Long (slow and controlled) | Faster |
| Clarity | High, even deep | Very clear for small pieces |
| Beginner Friendly | Moderate (needs skill) | Easy |
| Typical Uses | Tables, bars, big embeds | Coasters, keychains, art |
5. When to Use Deep Pour Resin vs Casting Resin
Use Deep Pour Resin When:
- You're making river tables
- You need thickness without cracks
- You want a smooth, high depth finish
Use Casting Resin When:
- You're creating jewellery or figures
- You want a casting resin kit for small moulds
- You need quick curing and easy handling
6. Tips for Best Results
- Always measure resin and hardener accurately
- Work in a clean, dust free area
- Use proper safety gear (gloves, mask)
- For deep pours, pour in layers if needed
- Mix slowly to reduce bubbles
Brands like Res-iT Epoxy offer clear deep pour and casting options that suit different project needs.
Conclusion
Understanding the difference between deep pour resin and casting resin helps ensure your projects turn out strong, clear, and professional. Deep pour resin is the most appropriate when dealing with heavy and bulky designs such as tables or countertops. A casting resin kit using transparent casting resin would work well if you are either making jewellery or miniature-sized figurines. Understanding the difference between art resin and casting maintains the results strong, beautiful, and long lasting. Discover, experiment and have fun resin crafting!
