can you epoxy a plastic tumbler?

Epoxy is a versatile material that can be used for a wide range of applications. It’s typically used to bond two or more materials together, such as wood or plastic.

Epoxy is also frequently used as an adhesive in arts and crafts projects. However, epoxy isn’t always effective on certain types of plastics.

Can you epoxy acrylic tumbler?

Acrylic is plastic, so it’s not recommended to use epoxy on plastic. If you want to use epoxy, go with glass or metal.

If you still want to use acrylic (or any other kind of plastic) then, yes, you can apply epoxy to an acrylic tumbler. Just make sure that the surface of your tumbler doesn’t have any scratches or cracks in it before applying the epoxy because it will make things difficult for yourself if there are any imperfections on the surface of your product.

How do you get epoxy to stick to plastic?

Epoxy is a glue that is used to bond two surfaces together. Epoxy is a two-part chemical compound that you mix together in equal parts and then apply to the surface that you want to stick. It’s a very strong adhesive, but it does not stick to everything.

Before attempting epoxy on plastic, make sure it’s safe for whatever material you’re sticking it on. The most common alternatives are rubber cement (which also uses solvents), silicone adhesives, or contact cement.

How do you glitter and epoxy a plastic tumbler?

To glitter and epoxy a plastic tumbler, you’ll need:

  • Glitter (like these ones)
  • Epoxy glue (we like this one)
  • A plastic tumbler with no writing on it (this is important!)

Is epoxy safe to use on plastic cups?

You should not use epoxy on plastic. Epoxy is not safe to use on plastic cups, tumblers, bottles, or any other type of plastic container.

Epoxies are chemically bonded substances made from a resin and an activator that harden when they are mixed together. Epoxies can be formed into shapes once they have been applied to the surface of your cup or bottle and left to dry completely before being cured by heat or ultraviolet light.

Epoxies can be used to repair existing items if they have been properly cleaned first in order to remove any dirt or grease that may prevent them from bonding properly with the original material being repaired; however, you should never attempt making any repairs with an epoxy unless you know exactly what type needs fixing as well as how long it will take for this material to cure once applied so that no damage occurs during this process (for example: If a large amount were used on top of another small piece already stuck onto another surface).

Can you epoxy plastic Starbucks cups?

Unfortunately, epoxy is not recommended for plastic cups. It is important to remember that while epoxy can be used in many different applications, it will not work on all surfaces. For example, if you have a scratch on your car or need to repair a broken cabinet door, epoxy may make an excellent choice as its adhesive properties will allow it to adhere strongly to the damaged surface and fill any gaps left by the damage itself.

However, if you are trying to bond two pieces of wood together with a piece of paper between them (like when making model airplanes), using epoxy will cause both pieces of wood—along with their attached paper—to become one solid mass and render your project useless.

The same principle applies when trying to use epoxy on plastics such as Starbucks tumblers or plastic cups: while they are both made up partially from petroleum-based materials like polypropylene plastics (PP) and polyethylene terephthalate (PETP), they also contain other elements such as aluminum cans which make them incompatible with certain solvents like cyanoacrylates.

How do you seal a plastic tumbler?

To seal a plastic tumbler, you can use one of the following methods:

  • Epoxy. This is a good option if you want to permanently attach something to your tumbler and are not concerned with whether it will chip or peel off later.
  • Glue gun. Use this method if you want to temporarily fill cracks in your plastic tumbler while decorating it with paint or decals, and then remove the glue when it’s finished.
  • Silicone sealant. Use this method if you don’t mind leaving some residue behind on your tumblers but want them to be watertight when they dry out again after being submerged in water for a long period of time (such as overnight).
  • Plastic sealant (like “Liquid Nails”). This will leave less residue than silicone but takes longer than epoxy adhesive does

What kind of epoxy is used for plastic?

Epoxy is used to glue plastic together, but it can also be used to glue plastic to glass and metal. Epoxy is a type of glue that works by hardening as the chemical bonds form between any two surfaces that are coated with epoxy resin.

In some cases, you may need more than one coat of epoxy if there’s a large surface area being bonded together. If you need help deciding what kind of epoxy will work best for the job at hand, consider reading our guide on how to choose the right epoxy for your project.

Is epoxy effective on plastic?

Unfortunately, epoxy does not work on plastic. While epoxy can be used to repair many materials, it’s not the best option when trying to repair plastic.

That’s because epoxy doesn’t stick well to plastic and is only slightly stronger than the material that you’re applying it to.

These two factors mean that if you use epoxy on your tumbler, you’ll have a weak connection between your two pieces of plastic—so much so that they might come apart under normal conditions (i.e., if someone bumps into your table).


Epoxy can be used to seal plastic tumblers and cups. However, it is not recommended that you use regular epoxy on them because they will not be able to handle the heat. Instead, use a heat-proof epoxy.

It’s also important that your cup or tumbler has been thoroughly cleaned before applying the epoxy so that no residue remains on its surface.
