What materials are needed to make an epoxy tumbler?

Before you start creating your personalized epoxy tumbler, prepare the following tools and materials:

• Stainless steel blank tumbler
• Epoxy resin kit
• Decorative materials such as glitter and pigments
• Tumbler turner
• Disposable mixing cups and stir sticks
• Measuring cups
• Gloves
• Face mask
• Heat gun or torch
• Sandpaper
• Painter’s tape
• Silicone mat

How to Decorate a Stainless Steel Tumbler with Glitter?

Glitter epoxy tumblers are one of the most popular epoxy tumbler designs because they create a bright and eye-catching finish. Whether you prefer a simple single-color glitter design or a multi-color gradient effect, glitter can completely transform the look of a plain stainless steel tumbler.

1. Clean the Tumbler Surface: Use rubbing alcohol and a lint-free cloth to remove dust, grease, and fingerprints from the tumbler surface. Any residue left behind can affect how well the glitter and epoxy resin adhere.
2. Sand the Tumbler Surface: Use 220-grit fine sandpaper to lightly sand the tumbler surface. This creates more texture and helps the resin bond better. After sanding, rinse the tumbler with clean water and dry it completely with a lint-free cloth.
3. Cover Areas that don’t need Decoration: Wrap painter’s tape around the rim, inside of the tumbler, and any areas where you don’t want to apply glitter or resin. Use high-quality painter’s tape, as it can be removed more easily without leaving sticky residue behind.
4. Mix the Epoxy Resin: Choose an epoxy resin kit specifically designed for drinkware and made with food-contact safety standards in mind. Pour the resin and hardener into a mixing cup using the recommended 1:1 ratio. Slowly stir in one direction for several minutes until the mixture becomes clear and free of bubbles. Keep in mind that mixing ratios can vary between brands, so always follow the manufacturer’s instructions.
5. Apply the Glitter: Before adding glitter, you can apply a spray paint base coat in a similar color to the glitter. This helps create a more vibrant and sparkling finish. Place the stainless steel tumbler on a tumbler turner and apply a thin layer of epoxy resin over the surface. Then, while the tumbler is slowly rotating, sprinkle glitter evenly based on the effect you want to achieve.
6. Apply the Top Coats: Apply two layers of epoxy top coat in total. For the first coat, apply a thin layer of epoxy resin to secure the glitter. Applying a thick coat all at once may cause the glitter to shift or become uneven. Wait at least 4–6 hours until the first layer has fully cured. Then, lightly sand the surface to create better adhesion before applying the second coat. Use a heat gun to remove bubbles, then let the tumbler cure at room temperature for 24–48 hours.

How to Decorate a Stainless Steel Tumbler with Resin Pigments?

Resin pigments offer more creative possibilities, allowing crafters to create more artistic tumbler designs. They are especially popular with customers who love unique and high-end styles.

Common pigment types include:

• Mica powder: Creates a metallic effect
• Liquid pigments: Creates solid color effects
• Alcohol inks: Creates flowing patterns

Here is a detailed tutorial on how to create a marble-effect epoxy tumbler:

1. Prepare the Tumbler: Use a lint-free cloth with rubbing alcohol to wipe the outside of the stainless steel tumbler and remove dust, fingerprints, and grease. Let the surface dry completely before moving on to the next step.
2. Mix the Resin Colors: Choose several different colors based on your design needs and mix each color evenly with epoxy resin. You’ll need about twice as much resin as you normally use because creating a marble effect requires pouring the colored resin directly onto the tumbler surface instead of spreading it around. Otherwise, all the colors will blend together and the marble pattern won’t form properly.
3. Mix and add Resin Pigments: Add each colored resin mixture into one mixing cup one by one, but don’t stir them together. Then place the stainless steel tumbler on a tumbler turner. You can freely add the resin colors onto the tumbler surface. As the tumbler rotates, the colors will continue to move and create beautiful patterns, gradually forming a marble-like effect.
4. Apply Layers (Optional): Another way to add pigments is to first apply a layer of your main color resin. Then use a toothpick or stir stick with a small amount of resin in another color and gently drag it across the base layer to create natural marble veins.
5. Remove Bubbles and Cure: Resin pigments usually take about 24 hours to cure. Once the design is fully cured, add a layer of clear epoxy resin to protect the marble pattern. Mix the resin and hardener at a 1:1 ratio, or follow the manufacturer’s recommended ratio. Apply it evenly over the tumbler, use a heat gun to remove bubbles, and allow it to fully cure for 24–48 hours.

FAQs for Creating Personalized Epoxy Tumblers

What safety precautions should you take when using epoxy?

Wear nitrile gloves to avoid direct skin contact with resin and hardener, which can help prevent allergic reactions. Epoxy resin has a strong odor, so make sure you work in a well-ventilated area and wear a mask. It’s also recommended to wear safety glasses to protect your eyes from accidental splashes.

How can you prevent bubbles when applying epoxy to a tumbler?

When mixing resin and hardener, stir slowly and let the mixture sit for a few minutes after mixing to allow bubbles to rise and disappear. When applying the resin, use multiple thin coats instead of applying a thick layer all at once, and spread it slowly in the same direction. After applying the resin, use a heat gun from a distance and gently move it across the tumbler surface to remove surface bubbles.

How do you clean epoxy from your hands?

If epoxy resin gets on your hands, wash them immediately with warm water and soap. If the resin is still stuck after gentle scrubbing, you can try using white vinegar or baking soda to help soften it before wiping it away.
