Best Epoxy for Tumblers Buying Guide

  • Safety

It is important to remember that all epoxy brands are toxic in liquid form, even if they are labeled food-safe. Epoxy is only safe to use when fully cured about 72 hours and after it has turned into an inert state. 

Choose an epoxy with low to no volatile organic compounds (VOCs), bisphenol A (BPA), and other phenols. It should also not be flammable. Most importantly, use an epoxy resin certified safe for art and home use and conform to ASTM D-4236 standard.   

  • Heat Resistance

Epoxy lowers the heat tolerance of a cup or tumbler. So if you want to use your tumbler or cup for hot drinks, stay away from epoxy. You should not use it for drinks hotter than 120°F. However, you can use epoxy to make coasters but not for wooden trivets for hot dishes. 

  • Curing Time

Curing time depends on the brand of epoxy. Some need 48 hours, while others require up to 72 hours. To turn an epoxy craft into entirely inert plastic, store it for 15-30 days at room temperature. Please note that curing time is affected by the surface’s temperature you are working on and the heat generated by the epoxy.

Epoxy works like blubber. The thicker it is, the more heat it generates. So, one way to hasten the curing process is to make your epoxy thick enough to keep the warmth in. But do not attempt to use insulators to help with the heat as it can cause spontaneous combustion. 

It is essential to allow at least 15 days for your tumblers to cure. Be sure to give the same instructions and precautions to your clients regarding the curing process, too. 

Pro Tip: Monitor your epoxy crafts during the curing process to prevent spontaneous combustion. If you observe smoke or if it feels too warm, move it outdoors. Do not inhale the smoke.

  • Versatility

You’ll appreciate your epoxy if it works on various media. This means economy and value for professional crafters. For beginners, it allows taking on different projects before picking a niche. 

Epoxy bonds with wood, stainless steel, glass, and fabric. It won’t bond with silicone, vinyl,  rubber, PE plastics, and surfaces with wax or grease. 

  • Viscosity

For epoxy tumblers, go for medium to high viscosity epoxy resin. It has the consistency of honeynot too runny but not too tough to pour. Viscosity also affects curing time, so the less watery the epoxy is, the longer it is to cure. 

Best Epoxy for Tumblers FAQ

1. What can I use instead of epoxy on tumblers?

Water-based polyurethane (CrystaLac) is an excellent alternative to use instead of epoxy for tumblers. It’s water-based, no VOCs, and non-toxic. You also won’t have to deal with allergic reactions with fumes from the epoxy components’ chemical reaction. It also has a better heat resistance of up to 350°F.

You won’t have to deal with fisheye, microbubbles, and other quality issues. It takes 10-15 layers of CrystaLac as opposed to 2-3 layers of epoxy. The drying time, though, is shorter, and the curing time is longer at 30 days.

2. How do you prepare a tumbler for epoxy?

There are few methods you can do to prepare your tumbler for epoxy. The first one is to use a cotton ball wet with 91% rubbing alcohol to clean the tumbler off of oils, adhesives, and dust. 

The second method is sanding it with a P400 or P600 sandpaper. Wash it with water and dishwashing liquid and let dry. You can also tape the tumbler’s mouth and base and then apply paint (spray or brush).

3. What causes fish eyes in epoxy?

Contamination is one of the most common but overlooked reasons for imperfections in your epoxy crafts. Remove all traces of grease, oil, wax, or silicone from your surface by washing it with dishwashing liquid and water or using cotton and rubbing alcohol. 

Another reason is not enough epoxy in the application. It is crucial to apply the correct amount of epoxy between coats, spreading it evenly with your gloved hand or fingers. 

Finally, lack of priming can also cause fish eyes. If the epoxy does not have enough grip on the surface, it will drip away. To solve this issue, sand off the smooth surface to increase the surface tension. You can also use flat paint to achieve a better grip.

4. How do you make epoxy cups smooth?

Preventing imperfections in your cup is easier than correcting an imperfect finish. If applied properly, the epoxy has a doming effect, giving it a smooth finish. 

Always prepare your tumblers well to remove all foreign matters on them. Apply just the right amount of epoxy to your tumbler and torch it to remove the air bubbles. 

Use a dust cover in the first 6 hours of applying epoxy to avoid dimpling. Also, be sure that your cup turner does not wobble or favor one side. 

However, if your cup turns out to have lumps and bumps, you can still work on it as long as the imperfections are not too noticeable. For ridges, you can just sand it off carefully, so the glitters or design is not affected, then apply a new layer of epoxy.  

If you have fisheyes or divots, you can correct it by sanding off uneven edges and applying another epoxy layer. Do not forget to torch after each application.  

Your cup turner’s improper speed may also cause the constant occurrence of fish eyes or divot. Some turners can go as high as 9 RPM, and it would be tempting to use them. If you are using adjustable speed cup turners, start with the regular 5-6 RPM, lower it to 3-4 RPM after 3 hours. 

5. Is epoxy safe to use indoors?

Yes, depending on the epoxy brand you use. Some products are certified home-safe, especially for arts and crafts, so you can use it indoors but only if it is well-ventilated. You can use fans but do not use air-conditioning.

That also means you need to take precautionary measures and wear protective gear. Always wear a good pair of safety goggles and nitrile gloves, a PVC apron, and a respirator.

Manufacturers always recommend working with epoxy in a well-ventilated area, all for good reasons. Combining the resin (A) and the hardener (B) produces a chemical reaction that releases harmful fumes. Inhaling epoxy fumes may result in allergic reactions and irritation of the respiratory organs.

Sanding epoxy also presents a danger to the mucous lining of your mouth, nose, windpipe, etc., resulting in respiratory irritation, inflammation, and allergic reactions.

The most common symptoms of epoxy fume and dust inhalation are shortness of breath, difficulty breathing, heaviness in the chest, and severe headache.  

Also, do not get epoxy on your skin. Repeated exposure can cause severe skin irritation, leading to eczema and other chronic skin problems. A single exposure of the eye, however, can cause serious eye infections and even blindness.
