We’re always curious about how people use epoxy resin and other adhesives. So we decided to ask: Can you put epoxy resin in a cup? The answer, as it turns out, is yes — but there’s a lot more to consider than just which kind of cups can be used for an epoxy project.
What kind of cups can you epoxy?
Just about any cup you have lying around can be epoxied. The best thing about this project is that it’s so versatile and easy to do.
You can use plastic cups, paper cups, glass cups, metal cups, ceramic cups—even Styrofoam bowls! They just need to be sturdy enough to hold up under pressure while they’re drying.
You can also use any kind of epoxy or resin and glue with this technique (we recommend Loctite Epoxy Putty).
The great thing about using different glues is that your options are endless: acrylic paint will stick better to certain materials than others; water-based paints will adhere better than oil-based paints; etcetera.

Can you epoxy plastic tumblers?
You can use epoxy to glue plastic tumblers, but you’ll want to sand the surface first. Make sure that the epoxy is completely dry before using it.
If you’re going to be drinking from an epoxy resin cup, make sure that there are no sharp edges or burrs on the inside of your cup.
Can you use epoxy on stainless steel tumblers?
You can use epoxy to seal stainless steel tumblers, but it’s not easy. The key is to apply the epoxy very thinly and let it dry for several days before tumbling.
This way you’ll have an even coat of epoxy with no gaps, which will prevent air from getting underneath it and causing bubbles when you run your rocks through them.
When you’re done with this project, make sure that you clean up every drop of metal dust so that no residue remains on your piece.
This can be tricky because metal dust tends to stick pretty well! If all goes well though…then you’ve got yourself a cool-looking set of tumblers made from materials that were destined for landfill!
Do you have to sand a tumbler before epoxy?
The answer depends on the type of tumbler you have. If it’s a molded plastic tumbler, like a Solo cup, you don’t have to sand at all. You can just epoxy right onto the surface.
If your tumbler is made of metal or ceramic, then no matter what kind of epoxy you use—regular resin or Urethane—you will need to sand before adding any epoxy.
It’s best to start by using an 80-grit sandpaper and work your way down through 400 grit until there are no scratches left in either surface (the glassware and metal).
Can you epoxy Starbucks cups?
Starbucks cups are made from paper, so you can definitely use epoxy to attach a handle, lid, and straw to your favorite Starbucks cup. If you’re looking for an easy way to customize your favorite mug, this is it!
Can you put epoxy on glass cups?
Absolutely! Any shape or size of glass cup will work. You can even try to use these methods with glass tumblers, mugs, and water bottles if they’re not too large.
That depends on what kind of project you’re trying to do — but in general, we recommend using epoxy with a high bond strength like Loctite Ultra Gel Control or JB Chemicals Quick Set 5 Minute Epoxy.
They’ll give you maximum durability while still allowing enough time for handling before drying completely (around 30 minutes).
Can you drink from an epoxy resin cup?
Many people wonder if it’s safe to drink from an epoxy resin cup. The answer is yes, you can drink from any cup that is made of plastic, glass, stainless steel, or vinyl. You can also drink from any cup that is made of any material.
How do you epoxy a vinyl tumbler?
Epoxy is a two-part adhesive that comes in liquid form. It sets to a hard, durable bond when the two parts are mixed together. To make epoxy, mix equal amounts of resin and hardener until the mixture is uniform.
Epoxies can be used for many applications, but for tumblers, it’s best to use epoxy made specifically for plastic products like vinyl.
The resin and hardener should be compatible with each other and must have similar viscosity (the thickness or thinness of a liquid) so that they’re easy to combine evenly when applied.
Epoxies come in different shades so you can choose one that matches your tumbler color if necessary; transparent are generally easier to work with than opaque ones because they don’t obscure any details on the surface being coated with them like decals do (more on this later).
Conclusion
Epoxy is a great way to add some personality and fun to your everyday drinking needs. It can also be used on other materials besides glass, including plastic and stainless steel.
With all of these different types of cups available it’s easy to find something that fits your needs. If you’re looking for something durable but still stylish then look no further than epoxy resin cups!
