Sooner than we think, summer will be here, and hydration is critical. Learn how to make an epoxy tumbler so you won’t have to carry around boring containers.

Epoxy tumblers can be made using three simple steps: prime your blank, apply glitter, and then encase it in epoxy. Sand the surface between each layer, torch the surface to remove air bubbles, and let it cure for 72 hours.   

For more experienced crafters, we included some fantastic epoxy tumbler designs along with this tutorial. There are also some tips and tricks for newbie crafters who may encounter difficulties during the process.

A TUMBLER EPOXY

Even beginners can customise their epoxy tumblers. To make an epoxy tumbler, you will need these tools and a detailed step-by-step guide.

Instructions on how to do it

1. Create a blank document

  1. Your tumbler should be label-free.
  2. Use rubbing alcohol to clean the stainless steel mug of all adhesive, dirt, and grime.
  3. Wrap the steel cup’s bottom and mouth with tape. 
  4. If you don’t want to see the stainless steel through gaps in the glitters, you can use a flat paint spray as a base before applying the glitters. Paint and glitters should be the same color.

2. Sprinkle glitter on the cake

  1. You will need a large piece of kraft paper or old newspaper to catch the glitters.
  2. Mod Podge or an adhesive spray should be applied in an even layer to the tumbler. Glitter is better held in place with adhesive spray, and it dries faster. Mod Podge is priced more expensively, however. 
  3. Pour glitters of choice into the tumbler, tapping the tumbler to remove glitters that do not adhere. Allow to dry.
  4. If you wish, you can repeat steps B and C to add a layer of glitter. 
  5. Use clear coat spray to seal your glitter.

3. Spread epoxy on the surface

  1. Using the cup turner, mount the glitter tumbler. Cover a baking sheet or foil dish with silicone so that drips will be caught. 
  2. Epoxy components A and B should be mixed at a 1:1 ratio. 
  3. You can now turn the cup turner on and apply the epoxy to the inside of the cup, spreading it out as you go. A silicone brush can be used if you are wearing gloves. 
  4. Bubbles can be removed with a torch. 
  5. 30 minutes after the timer goes off, remove the tape from the tumbler’s mouth and bottom. 
  6. Wet a paper towel with rubbing alcohol and wipe away any excess resin. It must be allowed to dry for 5 hours. 
  7. Make sure the mouth and the bottom of the tumbler are taped again. There should be no imperfections. Use an alcohol-soaked cotton ball to wipe the tumbler.
  8. The decals can now be added if you wish. 
  9. Steps C through F must be repeated. 
  10. Allow 48 hours for the cure. 

TUMBLER DESIGNS FOR EPOXY

Epoxy tumblers are easy to make, but do you have any idea how to transform them into beautiful and sellable works of art? The following designs may serve as inspiration for you if you want to turn your hobby into a business.

Making It

  1. Apply your epoxy to the tumbler after it has been primed with matte paint. 
  2. If you wish, you can add drops of alcohol ink while the epoxy is still wet and the cup turner is still rotatingTo add white Pi*ata ink to the tumbler, remove it from the cup turner.. 
  3. Add white pi*ata ink to the tumbler after removing it from the cup turner. Your colour swirls will now be clearly visible. 
  4. It is important to remove any air bubbles by torching it lightly. 
  5. After you’ve turned the tumbler for at least 6 hours, place it back into the cup turner to dry.

Making It

  1. Paint your tumbler with blue, pink, and yellow acrylic paint after priming it with flat white. Repeat the color placement until all the colors are used. 
  2. If you are going to use another color, be sure to rinse your brush and dab it dry. 
  3. Clean, wet paintbrushes can be used to blend the colors. Allow the paint to dry. 
  4. Let the paint dry after spraying it with flat white.
  5. After 15 minutes, apply a 1:1 mixture of Tack-it and waterRub off the excess glitter after covering it with white pearlescent glitter..
  6. Rub it down to remove excess glitter after covering it with white pearlescent glitter. Spray it with clear acrylic spray twice. 
  7. Once the air bubbles are removed, you can apply epoxy and torch. 
  8. Add the white chunky glitters without letting them dry. The second and third epoxy layers can be added after the first layer has dried for 4 hours.

Making It

  1. Use 91% rubbing alcohol to clean your tumbler. You can spray it with the flat paint of your choice, but the example used black and light pink.
  2. The ombre effect can be achieved by spraying the paint alternately. After the epoxy has dried, drizzle hot pink glitter over it and let it dry.  
  3. After the glitters have dried, apply another layer of epoxy. Afterwards, sand the epoxy and apply the leopard spots.
  4. Let the epoxy dry after applying the first layer and blowtorching. Afterward, sand the final layer and apply more epoxy. Then torch again and leave the epoxy to cure for 72 hours.     

Epoxy Tumbler Pour-on 

Epoxy Tumbler Pour-on 

Using a cup turner isn’t necessary to epoxy a tumbler with this one. Rub alcohol on your stainless steel cup before starting.

Making It

  1. Pour your pouring paint into a small bowl, alternating colors to achieve a marbled effect later. Avoid mixing. 
  2. Allow some space between your cup and the table when inverting your cup to a plastic cup. 
  3. Allow the paint to flow to the sides of the tumbler as you pour the paint over the bottom. Allow it to dry.
  4. Your epoxy resin is now ready to be applied. It is recommended to apply two layers, letting each one dry for at least six hours in between. 
  5. Sand between layers after torching your tumbler.   

A TUMBLER DRIES an epoxy in how long?

Allow 12 hours between applying coats to your tumbler while you are still working on it. A second layer of epoxy can be applied once the first one has dried enough to be sanded off. 

It is commonly recommended that you leave the second coating on the turner for another 12 hours. Your tumbler should now be ready to be removed. 

You should leave the tumbler for 48-72 hours to cure so that it is completely dry to touch. From start to finish, a tumbler requires you to work at least 86 hours.

POXY TUMBLERS – COMMON ISSUES

This DIY cup turner tutorial addresses some of the most common problems with commercial cup turners:

Finished with a lumpy texture 

It is possible for your epoxy to flash cure if you leave it in the container. During the hardening process, the epoxy gets hot and becomes lumpy. It won’t dry evenly either. 

Make sure you have the time to mix epoxy before you begin. When it comes to how to epoxy a tumbler, multitasking is not one of the tricks.

There is no way to remove the tapA minimum of 12″ should be left between your tumbler’s lip and its bottom.e

The lip of your hot beverage tumbler should have at least 12″ of space between it. If you do this, your lips will not be in contact with the epoxy as you can drink from the cup directly. You can do this by taping around the lip. 

Tape must be removed when epoxy is dry. Wait at least 30 minutes for the epoxy to set before slowly removing it. Rub rubbing alcohol and paper towels together to clean off messy adhesive residues

Compiling epoxy into bundles

For the epoxy not to bunch up, it should not be too viscous. Epoxy gathers where gravity favors it because of changes in surface tension. 

This problem can be resolved by using a slower cup turner, which evens out the drying process. Apply a thinner layer of epoxy and make sure it is evenly distributed with your gloved fingers. 

A clear, acrylic-based spray can also be used as a hack. When compared to a cup without a base, the epoxy bonds better with this base. 

Resin that sticks to your fingers

Your epoxy may not cure or dry perfectly for these three reasons:

Components with uneven distribution

If you want your epoxy resin to harden faster, don’t add more hardeners to the mix. This will result in no hardening. Manufacturers recommend a 1:1 hardening ratio.

There is not a good mix of components

Make sure you mix everything well. Combining the components with mixing leads to two results: better consistency among the epoxy components. The problem with poorly integrated epoxy resin is that it can also produce a tacky finish that does not cure. 

Better results come from good consistency. The epoxy mix should pour easily without dripping. If there are bubbles, simply torch over the epoxy to remove them.  

Temperatures and humidity fluctuate

Temperatures below 70F can make it challenging. If you’re working on resin crafts, you should keep the temperature between 275 and 86F. Within the first 24 hours, please keep your workstation at the temperature range mentioned, so that the resin can dry out. A heat box can help you do this.

Resins should be kept between 20 and 75 degrees Fahrenheit. Use two measuring cups to measure your resin components, and let them rest in a bowl of warm water if it’s too For the right temperature, use cold water. Before mixing, you should warm each element separately.

It is also important to take humidity into consideration when you do epoxy tumblers. Heat lamps with thermostats and hygrometers are excellent investments to keep your work safe from damage caused by fluctuating environmental conditions.
