- Carefully prepare your tumbler by sanding and washing it then applying your flat paint.
- Apply Mod Podge with a brush applicator, then cover your tumbler with glitters. Let it dry.

Common Issues When Sealing a Glitter Tumbler Without Epoxy
Here are some of the most common issues when dealing with glitter tumblers without epoxy. It's important to be aware of them to help manage your expectations.
Less Water Resistant Finish
Aside from the water-based CrystaLac, Mod Podge and clear acrylic spray do not have a water-resistant finish. This means that you cannot leave your tumblers in the water or other liquids for extended periods.
Long Curing Time
CrystaLac takes 5 days to be thoroughly dried and 30 days to cure to an inert state. The other alternatives take less time, but the quality is not as good as epoxy. The clear acrylic finish can be baked to improve quality and curing time, but there’s no such luck for CrystaLac and Mod Podge.
CrystaLac reacts with alcohol ink, so you cannot use this design for your tumblers. The Mod Podge also has limited application, and baking clear acrylic finish is not always an option for all designs.
Except for woodwork, you cannot use the alternatives to epoxy for tumblers for resin crafts like jewelry, keychains, coasters, and more. CrystaLac may work for these resin arts, but it takes longer for it to dry and cure.
If you are allergic to epoxy fumes, now you can make glitter tumblers without using one. The overall quality may not be the same, but it’s worth the try.
Although there are various alternatives on how to seal a glitter tumbler without epoxy, we found that CrystaLac is the best choice since it is water-based, does not contain aerosol, and does not induce allergic reactions. The most significant disadvantage of using CrystaLac is the curing time, although epoxy also needs 30 days to be fully cured and inert. On that note, you can safely use CrystaLac-finish glitter tumblers after 5 days.
