can you put epoxy on a plastic tumbler?

With all of the different craft projects out there, it’s pretty amazing how many people still ask “Can you put epoxy on a plastic tumbler?” The answer is yes!

While we’ll go over the process for applying epoxy to plastic in this article, I should note that it can be difficult to get good results without professional help. This isn’t because epoxy doesn’t work on plastic—it does!—but rather because most DIYers don’t have access to good quality resin or know how to use it properly.

If you’re serious about using epoxy resin as part of your project then you really should hire an experienced crafter who knows their way around their materials…

Can you epoxy a plastic tumbler?

Epoxy resin is a strong adhesive, but it’s not recommended for use with plastic. In fact, epoxy does not bond to plastic very well at all.

Epoxy is typically used in situations where you’re gluing two pieces of wood together or some other material that it doesn’t readily bind to (like glass).

While epoxy can be useful in certain instances, you should proceed with caution when using it on a Starbucks cup, plastic tumbler, or any other type of plastic container.

In addition to the difficulty of bonding with these types of materials, there are several reasons why using an epoxy resin may not be ideal when trying to repair your broken Starbucks cup:

  • The chemicals in some types of epoxies can corrode metal over time and cause leaking issues down the road;
  • And because most plastics are porous (they absorb liquids), if you accidentally get some liquid into one side while working on another side then that could lead to future problems;

How do you glitter and epoxy a plastic tumbler?

You can use a glitter glue pen to add glitter to your epoxy. You can also use a glue stick, or even a hot glue gun if you’re feeling fancy.

If you want more control over the placement of your glitter, try using an applicator bottle with some of our clear epoxy and adding it directly on top of the glass as an overlay before applying another layer of epoxy over that.

If your goal is just to cover up some scratches in your plastic tumbler and make it look pretty again, then any kind of transparent coating will do!

Just be aware that if you want any kind of shine on top once it dries (like we do), then you will need something like our clear epoxy instead since our opaque colors don’t have any shine at all when dry

How do you make epoxy stick to plastic?

You can use super glue or epoxy to attach the plastic tumbler to the base. Both are strong adhesives that can hold onto a variety of materials, including glass and metal.

If you’re working with a smaller piece of plastic, try using epoxy putty instead of regular epoxy. This will help it stick better and make for a stronger bond between your project and the base.

If you’re trying to put together something more complicated or intricate (like an entire room), you might want to consider using resin glue instead of regular glue or even epoxy resin.

Resin glues are extremely strong adhesives that tend to be used in industrial applications like attaching furniture pieces together during construction jobs or attaching large panels together on airplanes before they take off into space!

Can you epoxy acrylic tumbler?

To create the glitter effect, you need to make a small hole in the tumbler and then use glitter glue to fill it. When you are done, fill the hole with epoxy.

This can be done by mixing the epoxy and water at a ratio of 1:1 and pouring it into the tumbler from above until there is no more space left inside (see photo).

Is epoxy safe on plastic?

Epoxy is not safe for plastic. It’s also not safe for children, pets, food or drinking water. If you’re curious about how epoxy would affect your skin, it probably wouldn’t be good either!

Epoxy has been known to cause respiratory problems and even death in some cases. Because of this, epoxies should never be used indoors or around children under 3 years old.

Will epoxy resin bond to plastic?

An epoxy resin is a polymer that forms an adhesive bond when mixed with hardeners. It’s widely used in manufacturing, construction and marine applications for its ability to bond materials such as wood and metals as well as to fill voids.

You may be wondering if you can use epoxy resin to adhere a plastic surface. The answer depends on what kind of plastic you’re working with and how much work you want to put into it.

Epoxies are not designed specifically for adhering plastics together, so they won’t do the job perfectly on their own. That said, epoxies are known for being flexible enough that they can stick fairly well to some plastics when given enough time to cure properly (which means letting them sit overnight).

Before applying an epoxy onto any type of surface—whether plastic or otherwise—it’s important that both surfaces are clean, dry, and free of dust or other contaminants because these could interfere with the chemical bond between them once mixed together into an adhesive compound called “resin” during curing time (which typically lasts 24 hours).

What is the best epoxy for plastic?

That depends on the material you’re using.

Epoxy is a two-part resin that cures to form an extremely strong bond. It’s often used for sealing, gluing, and filling small cracks, but it can also be used as a coating for decorative purposes, such as adding a shine to plastics or giving them color.

Epoxy comes in different colors and levels of glossiness depending on which kind you buy, so be sure to check out your options before deciding on which one is right for your project!

What kind of epoxy should I use? In general terms: polyester resin (commonly known as “resin” or “PVC”), polyurethane resin (or “PU”), acrylic resin (or “acrylic”) and methacrylate ester resin (or “MAE”).

Generally speaking there are two types of each type: one that hardens quickly but isn’t quite as durable/strong as the other type and vice versa (there are some exceptions – PU can sometimes be stronger than PVC).

If durability isn’t an issue then either will work just fine; however if durability matters then consider getting something like MAE instead since that tends not only be more durable but also cheaper than its counterparts too!

Can you use epoxy on plastic Starbucks cups?

Yes, you can use epoxy on plastic Starbucks cups. If you want to make sure the epoxy sticks to your plastic Starbucks cup and makes the resin bond properly, here’s what you should do:

  • Clean off all dust from your Starbucks cup with a damp cloth so that there are no particles left on its surface. This will prevent them from getting into your mixture and causing bubbles or micro-cracks in the finished product.
  • Cut out two pieces from a small piece of paper (such as index cards) large enough for each side of the cup—one should be slightly larger than the other—and apply petroleum jelly or cooking oil along one side of each piece before placing it onto one side of your coffee tumbler so that it acts as glue between both layers of paper/epoxy later when pressed together.


I hope this article has given you some insight into whether or not epoxy can be used on plastic tumblers. I know that sometimes it can be difficult to find the right glue for certain projects, but if you have a clear idea of what type of glue you’re looking for then it shouldn’t take too long before you find something suitable!

If all else fails though, just remember: there are no stupid questions in life (because who doesn’t want more knowledge?).
