  • Epoxy resin is a versatile material widely used in crafting, particularly for giving tumblers a durable, glossy finish. It not only protects tumblers from scratches but also enhances their appearance, making them perfect for custom designs and personalized gifts. When selecting epoxy for tumblers, it’s crucial to choose a food-safe, durable option that cures hard and clear, resists yellowing, and minimizes bubbling. The ideal epoxy should also be easy to mix and apply without excessive dripping or running. We tested several epoxy brands to find the best ones for creating smooth, long-lasting finishes that are user-friendly, even for beginners.

    Pros

    • Simple 1:1 mixing ratio
    • Self-leveling formula
    • Fast 8-hour curing time

    We tried out the Teexpert Crystal Clear Epoxy and found it to be a solid choice for tumbler projects. The 1:1 mixing ratio made it easy to get started, even for beginners. We liked how it self-leveled, saving us time and effort in spreading it evenly.

    When we used it, the epoxy cured quickly. It was solid in just 8 hours, which let us finish our projects faster. The clear finish looked great on our tumblers, showing off the designs underneath nicely.

    We did notice a few things to watch out for. It’s important to mix this epoxy well – we found that stirring for 8-10 minutes gave the best results. The working time was only about 30 minutes, so we had to move quickly. Some users might find the cured epoxy a bit flexible, but we didn’t have any major issues with this on our tumblers.

    One thing we noticed was the quick curing time. At room temperature, we had about 30-40 minutes of work time, which was plenty for our projects. The epoxy set hard within 8 hours, though we’d recommend waiting a full 24 hours for the best results.

    We loved the crystal clear finish on our tumblers. The epoxy dried completely transparent, showcasing the designs underneath beautifully. It’s also UV resistant, so we’re confident our creations will stay looking great for a long time. While we did see a few tiny bubbles, they were minimal compared to other epoxies we’ve used.

    • Quick 12-hour cure time
    • Super glossy result
    • Low odor formula

    The self-leveling feature worked well on our cup turner. We got a smooth, even coat without much effort. After 12 hours, the epoxy was cured enough to handle, which sped up our project timeline.

    One thing to note – while the finish is super glossy, we did see some yellowing after a few months. This wasn’t a deal-breaker for most colors, but it did affect our white tumblers. If you’re working with light colors, you might want to keep this in mind.

    We think this epoxy is a top choice for tumblers due to its quality, versatility, and ease of use.

    • Easy to mix and apply
    • Resists yellowing
    • Made in the USA

    Cons

    • Limited pour size for castings

    • May be pricey for large projects

    We’ve put Art ‘N Glow’s clear epoxy through its paces, and it’s truly impressive. The 1:1 mix ratio makes it a breeze to prepare, even for beginners. We found the 40-minute work time gave us plenty of time to pour and adjust our tumbler projects without feeling rushed.

    The finished result was crystal clear, thanks to the epoxy’s self-leveling properties and bubble-release tech. We didn’t spot any bubbles in our tumblers, which is a huge plus. The UV stabilizers seem to work well too – our older projects haven’t yellowed at all.

    We like that it’s made in the USA, which gives us confidence in its quality and safety. It’s food safe and low odor, so we felt comfortable using it in our kitchen. The 80+ Shore D hardness after curing makes for tough, durable tumblers that can stand up to daily use.

    We think this epoxy resin kit is a great choice for tumbler enthusiasts looking for a clear, bubble-free finish.

    Pros

    • Crystal clear results
    • Easy to mix and use
    • Low odor formula

    Cons

    • Caps can be tricky to remove
    • Long curing time
    • May yellow over time

    We tested this LET’S RESIN epoxy kit on several tumblers and were impressed with how clear the finished product turned out. The 1:1 mixing ratio made it simple to get the right proportions, even for us as beginners. We noticed very few bubbles forming as we worked, and those that did appear mostly vanished on their own within an hour.

    The low odor was a big plus in our book. We didn’t need to wear masks while working with this resin, though we still made sure to use it in a well-ventilated area. The kit comes with enough resin and hardener to coat multiple tumblers, making it a good value for the price.

    One thing to watch out for is the bottle caps – we found they can get stuck if not screwed on straight. The curing time was also longer than we expected, taking over 24 hours for some deeper pours. While the manufacturer claims it resists yellowing, we’d want to test it over a longer period to be sure. Despite these minor issues, we think this kit is a solid choice for most tumbler projects.

    • Low odor and non-toxic
    • Durable and scratch-resistant

    Cons

    • Mixing cups could be larger

    We found the Shabebe Crystal Clear Epoxy to be a great choice for tumbler projects. The 1:1 mixing ratio made it simple to prepare, and we appreciated the low odor during application. This epoxy gave us plenty of working time to add pigments and create designs.

    The finish was impressively clear and glossy. After curing, our tumblers had a rock-hard coating that seemed very resistant to scratches. We liked that it’s FDA food safe, so we felt comfortable using it for drink containers.

    One small issue we noticed was that the included mixing cups were a bit small for larger projects. We also had to be careful to mix slowly to avoid introducing bubbles. While the 24-hour cure time is longer than some quick-set options, we felt the results were worth the wait. The durability and clarity of the finished product made this epoxy a solid choice for tumbler enthusiasts.

    We think this epoxy is a great choice for tumbler makers who want a durable, UV-resistant finish.

    We think this epoxy is a great choice for tumbler makers who want a durable, UV-resistant finish.

    Pros

    • Easy 1:1 mixing ratio
    • UV-resistant formula
    • Versatile for many projects

    Cons

    • Requires careful temperature control
    • 7-minute stirring time
    • Can bend if too thin

    We tried out the Alumilite Clear Cast Plus on several tumblers, and we were impressed with the results. The 1:1 mixing ratio made it easy to get the proportions right, even for beginners. We noticed fewer bubbles compared to other epoxies we’ve used, which gave us a smoother finish.

    The UV-resistant formula is a big plus. While no epoxy can completely stop yellowing, this one seems to slow it down. We left a test piece in direct sunlight for a few weeks, and it stayed much clearer than others we’ve tried.

    We did find that temperature control is important. In a warm room, thin layers can bend. We got the best results when we kept the room cool and made sure our layers weren’t too thin. The 7-minute stirring time felt long, but it paid off in the final product’s clarity.

    Mixing was a breeze, and we noticed fewer bubbles compared to other epoxies we’ve tried. The liquid poured smoothly onto our tumblers, creating an even coat. After curing, the finish was crystal clear and super glossy, giving our projects a professional look.

    We liked that this epoxy had minimal odor, making it pleasant to work with in small spaces. The formula seemed pretty forgiving for newbies, but it still dried hard and durable. Our finished tumblers held up well to everyday use without yellowing or cracking.

Buying Guide

When choosing epoxy for tumblers, we recommend considering a few key factors:

Cure Time

Faster curing epoxies set quicker but may be trickier to work with. Slower cures give more working time but take longer to finish.

Viscosity

Thinner epoxies self-level better. Thicker ones are less likely to drip but may need spreading.

Heat Resistance

Look for epoxies rated for at least 120°F to prevent softening from hot drinks.

UV Resistance

This helps prevent yellowing over time, especially for clear or light-colored tumblers.

Food Safety

Make sure the epoxy is FDA-approved for food contact once fully cured.

Hardness

A Shore D hardness of 80+ provides good scratch and impact resistance.

Clarity

Crystal-clear epoxies showcase designs best. Some have a slight amber tint.

We suggest testing a few options on scrap material first. This lets you get a feel for working with different formulas before committing to a full project.

Proper safety gear is a must when working with epoxy. Always use in a well-ventilated area and wear gloves, eye protection, and a respirator.
