can you use epoxy on acrylic tumblers?

Yes, you can use epoxy on acrylic tumblers. Although epoxy is a strong adhesive, it will not bond with acrylics. Epoxy is best suited for bonding two different surfaces that can be sanded and painted together.

For example, if you want to bond fiberglass and wood together so that they are sturdy enough to withstand weathering or other outside elements, then epoxy would be the best option for gluing them together.

How do you epoxy acrylic tumbler?

Epoxy is a two-part adhesive that comes in a liquid form. You will need to mix the epoxy with hardener before you can use it, so be sure you know how much hardener your epoxy needs.

The manufacturer’s instructions should tell you how much of each part you’ll need, but if they don’t or if they’re unclear, try mixing equal parts epoxy and hardener as a starting point to see what works best for your project.

Once the epoxy has been mixed thoroughly, pour it into any clean container such as an old yogurt cup or popsicle stick so that you can easily apply it directly to the acrylic tumbler without spilling any.

Use a toothpick or piece of scrap cardboard cut into an applicator shape (a triangle works well) to spread an even layer over the sides and bottom of your tumbler using small strokes from left to right (or vice versa). Let dry completely before trying out new drinks!

Can you epoxy over acrylic paint on a tumbler?

Yes, you can epoxy over acrylic paint on a tumbler. However, you will need to sand the acrylic paint off the tumbler with sandpaper first. There are also some products that can remove the acrylic paint without having to sand it out.

These include tumbler cleaners like Simple Green or Kaboom Scrub-Free Tumbler Cleaner (available at Lowes).

How do you seal acrylic tumblers?

If you’re wondering how to seal acrylic tumblers, there are a few options. Some people use spray paint for acrylic tumblers before epoxy, but that can be tricky to get right.

Epoxy over acrylic paint on a Starbucks cup works great! You’ll need some disposable plastic cups or bowls and rubber gloves, though.

If you want your epoxy coating over the top of an acrylic tumbler to last longer than it would otherwise with just regular epoxy (and who doesn’t?), then consider using heat-resistant glassware instead of plastic.

If that’s still not enough protection for you, go ahead and try some other kind of coating—but expect that it won’t last as long as your new favorite beverage container might otherwise have done without any additional treatment at all!

Can you use epoxy on plastic tumblers?

It’s fairly easy to use epoxy on plastic tumblers. The key is to sand the inside of your cup and coat it with a thin layer of epoxy. Then let it dry for about 15 minutes, and you’re ready to carve your design into your cup!

If you want to use epoxy glue on Starbucks cups or plastic cups, then make sure that those objects are clear in color. You don’t want any coffee stains or dirt interfering with your design because that would make it look dirty.

Can you use epoxy on plastic Starbucks cups?

To make sure your cups are as safe as possible, you’ll want to use a primer to seal the plastic. This will help prevent any damage and make it easier for epoxy to adhere.

The best thing about acrylic tumblers is that they’re reusable, so if you want to get creative with them, I’m sure there are other ways in which you could display them.

How do you customize acrylic tumblers?

Acrylic tumblers are easy to customize with permanent markers, paint pens, and paint markers.

  • If you want to write on your acrylic tumbler, use a Sharpie or a paint marker. You can also use a permanent marker if you want the ink to be more permanent, as opposed to when you use an erasable pen.
  • To decorate your acrylic tumbler with designs and patterns, look for paints that do not require priming the surface before painting them (most acrylic paints will work). If your design requires multiple colors in one area of your tumbler, make sure that each color is completely dry before adding another layer of paint.

You can also use different types of tools like stencils and stamps on top of any base coat of white or colored paint!

Do you have to spray paint a tumbler before epoxy?

No, you don’t have to spray paint a tumbler before epoxy. Epoxy can be used over acrylic paint and will stick to the surface of your tumbler just fine. You can use it as is without any prep work!

How do you seal a painted tumbler?

To seal your acrylic tumbler, you can use a clear coat or a matte coat. A clear coat is glossy, while a matte coat has no shine to it. If your acrylic tumbler was painted with acrylic paints and you want to use the same type of paint again, then choose the clear or gloss finish.

If you want to change things up with different types of paints or if this is not possible because it’s a handmade item, then try choosing between flat and satin finishes for sealing purposes.


If you have an acrylic tumbler that is stained from coffee or other beverages, the easiest way to clean it is by using an acrylic cleaner.

You can also use soap and water for this process, but if your tumblers are really dirty you should definitely consider cleaning them with an acrylic cleaner first as it will help get rid of any dirt or grime that may be affecting their appearance.

After cleaning your tumblers with soap and water put some acetone on a cloth and wipe it around until all of the soap has been removed from inside your cup.

This will ensure that when you are finished there won’t be any residue left behind on parts where epoxy would not stick well such as around the rim of glassware because they don’t want anything interfering with how well they adhere together while curing!
