Step 1: Prepare your work surface and tumbler

Start preparing your workspace, cover your work table with plastic or old newspapers. You can also mask your tumbler with painter’s tape if you want any part of it to be without epoxy. It is recommended to mask the edges of the tumbler that are plastic.

Step 2: Paint the tumbler

Once you’ve finished protecting the areas you don’t want to epoxy, paint the outside of the tumbler if you like.

Using the spray paint of your chosen color, spray in short, quick bursts until the tumbler is completely covered. Try not to apply too much paint so that it does not spill. Let the paint dry between coats.

To paint you can place the tumbler in the turner.

Step 3: Add a lot of glitters

Once you have the tumbler painted, it’s time to add glitter! If you don’t want a glitter tumbler you can skip this step of the tutorial.

You can buy glitter paint directly or make it with Mod Podge and glitter. For the second method, apply a layer of Mod Podge to the outside of the tumbler and generously sprinkle glitter all over the surface of the tumbler until completely covered.

If the glitter doesn’t cover enough, you can repeat this process after the Mod Podge dries.

Remember to place paper under your tumbler while you sprinkle it with glitter so that you can save the excess and use it for other projects.

Step 4: Mix the Epoxy Resin

Before mixing the epoxy resin it is important to add painter’s tape to the inside edge of the cup to prevent the dripping of resin into the cup.

Also, if you’re going to drink directly from the tumbler, make sure your resin is food-safe or mask the top rim on the outside of the tumbler with tape as well.

To prepare the resin, use gloves. Epoxy resin comes in two parts: part A is the resin and part B is the hardener.

Measure the resin components in equal parts (I recommend you to use a measuring cup) and then pour both into a bowl to mix them well. Use a stick to stir gently, being careful not to stir too quickly so bubbles don’t form.

Then divide this into as many smaller containers based on how many colors you want to use.

Step 5: Apply the resin to your tumbler

Place your tumbler on the turner and while turning, slowly pour in the resin.

You can use a wooden stick, your gloved finger, or a silicone brush to spread the resin gently.

Be sure to cover your tumbler completely, except for the places masked with painter’s tape.

It is normal for some air bubbles to rise to the top of your epoxy. To remove the bubbles, use heat, which can be from a heat gun or a blowtorch.

Step 6: Cure the Resin tumbler

When you have finished pouring the resin into your tumbler, wait 10-20 minutes and remove the tapes you put on earlier. If you wait until the resin dries, the tape could get stuck or leave marks on the tumbler.

After removing the tape, let the tumbler continue to spin until the resin is dry to the touch, this takes approximately 4 hours. Once the resin stops dripping, you can turn off the motor but leave the tumbler in place for approximately 24 more hours. If you slow down the tumbler turner too quickly, the epoxy can drip and not dry evenly.

If you find it necessary, you can repeat the process to give your tumbler an extra layer of epoxy resin.

Step 7: Clean the tumbler

Once your tumbler is dry, I recommend that you wash it before using it. Finally you can put a vinyl phrase or drawing if you wish.
