From gorgeous river tables to jewelry and crafts, epoxy resin allows DIYers and professionals to create stunning projects. However, not all epoxy resins are created equal. Choosing the best epoxy resin is crucial for achieving optimal results on your specific project.
Epoxy Resins
Epoxy resins offer superior strength, durability, chemical resistance, and water resistance compared to many other adhesive options. Once cured, epoxy resin creates a glossy, glass-like coating that can be sanded, drilled, painted, and more. This makes epoxy an incredibly versatile material for countless applications.
While all epoxy resins share some core characteristics, certain formulations are better suited for specific projects based on factors like cure time, viscosity, maximum pour depth, and more.
Key Types of Epoxy Resins
There are several main types of epoxy resin to consider for your project:

Key Factors When Choosing an Epoxy Resin
With so many types of epoxy resin available, it can be tricky to select the best option for your specific project. Here are the most important factors to keep in mind:
1. Intended Application
The first step is determining how you plan to use the epoxy resin. Some key applications include:
- Tabletops/bar tops
- Wood finishes
- Flooring
- Crafts and jewelry
- Artwork and resin art
- Adhesives
- Clear casting/embedding
Matching the resin to your application is crucial for optimal results.
2. Ease of Use
Consider how user-friendly the epoxy is to mix, pour, spread, and clean up. Options like pumps, pre-measured containers, and squeeze bottles can simplify the process for beginners.
3. Cure Time
Cure time refers to how long the epoxy takes to fully harden once mixed. This can range from 5 minutes to 72+ hours depending on the resin. Fast cure epoxies work well for repairs and small projects. Slow cure epoxies are needed for large/deep pours to allow for bubble release.
4. Viscosity
Viscosity describes the thickness of mixed epoxy resin. Low viscosity epoxies spread easily and are great for coating surfaces. High viscosity epoxies are thicker and optimal for pouring deeper molds.
5. Clarity
The clarity of cured epoxy ranges from crystal clear to slightly amber. Ultra clear options are best for applications like jewelry and artwork where visibility is key.
6. UV/Scratch Resistance
If your project will be exposed to sunlight or high abrasion, seek an epoxy formulated to resist yellowing and scratches. Outdoor projects especially benefit from UV-resistant epoxy.
7. Maximum Pour Depth
Deep pour epoxy resins are needed for thick pours deeper than 1/4″. Check the manufacturer’s recommended maximum depth and be sure to account for your project size.
8. Food Safety
For tabletops or surfaces that will contact food, ensure you choose a food-safe epoxy resin made without toxic chemicals.
9. Temperature Resistance
If exposure to high temps is a factor, select a high heat-resistant epoxy with a HDT (heat deflection temperature) over 100°F.
10. Special Properties
Some epoxies offer unique properties like flexibility, vibration dampening, chemical resistance, chip resistance, and more for specialty applications.
How to Choose the Best Epoxy Resin Brands
With countless epoxy resin brands on the market, it can be tricky evaluating which manufacturers produce the highest quality options. Here are a few tips for choosing reputable brands:
- Seek out established companies – Brands like West System, Smooth-On, and TotalBoat have been producing epoxies for decades and have proven track records.
- Read third party reviews – Don’t just rely on a brand’s marketing claims. Check reviews from independent sources to assess real-world performance.
- Compare technical specs – Reputable brands provide detailed product datasheets so you can compare viscosity, work time, strength, clarity, and other vital specs.
- Contact customer service – Reach out with any questions you have to gauge the helpfulness of their technical support. Quality brands will provide thoughtful guidance.
- Consider value – While cheaper epoxies lure with lower prices, quality resins often justify slightly higher costs through performance and results.

Frequently Asked Questions About Epoxy Resins
What is the difference between epoxy and polyurethane?
Epoxy cures through a chemical reaction between two parts, while polyurethane cures with exposure to moisture in the air. Epoxy also offers higher strength, scratch resistance, and durability compared to polyurethane.
Should I use heat to cure epoxy faster?
Never use direct heat like a heat gun to attempt to accelerate epoxy curing. This can severely compromise the strength and clarity of the resin. Always follow the manufacturer’s recommended cure times.
How do I prevent bubbles in poured epoxy?
Using propane torches or heat guns to pop surface bubbles right after pouring can help prevent bubbles in the cured epoxy. Letting the resin sit for 10 minutes before torching allows bubbles to rise fully.
What’s the best way to clean uncured epoxy off surfaces?
Uncured epoxy can be cleaned up with isopropyl alcohol, acetone, or other solvents. Never allow epoxy to fully cure on surfaces before attempting to remove.
Can I thin or dilute epoxy resin?
No, never attempt to thin epoxy with solvents like acetone or alcohol. This will prevent proper curing. Only use epoxy as directed by the manufacturer.
