“How much epoxy do I need for a tumbler?” That’s a great question and we’re going to answer it in this detailed guide. However, you need first to ensure that you are armed with the best epoxy resins for tumblers so that you can get the best results.
Once you get your epoxy, you can get started. The truth is that the amount of epoxy you need for a tumbler depends on the size of the tumbler you’re working on.
Therefore, for the purposes of this guide, we’re going to be explaining with a 20 oz tumbler. If you are working with any other size of the tumbler, you can estimate how much epoxy resin you need from this.
So, for a 20 oz tumbler, you’ll need 10 ml of epoxy resin. This is 5 ml of A-side epoxy and 5 ml of B-side epoxy. Remember to measure them in separate measuring cups. You should notice that the A-side epoxy is thicker than its B-side counterpart.
There you have it. That’s how much epoxy you need for a tumbler. Now, we’ll look at how to mix your epoxy resin for tumblers and the type of tumblers to use.
How Do You Mix the Right Amount of Epoxy for Tumblers?
Once you have your two 5 ml epoxy resins for tumblers with you, the next step is to mix them carefully. Next, you’ll take the measuring cup with the 5 ml A-side epoxy resin and pour its contents into a clean mixing cup.
Use a clean popsicle stick to ensure that you’ve got all the resin. Next, take the measuring cup with the 5 ml B-side epoxy resin and add its contents into the mixing cup with the A-side epoxy.
After you’re sure that it’s all in, take the popsicle stick and mix the two epoxy resins together. The mixture will look cloudy in the beginning but continue stirring until it clears out.
How Do You Apply Epoxy for Tumblers?
Ensure you have a tumbler spinner or cup spinner for the best results.
Attach the tumbler to the cup spinner and let it spin slowly as you carefully pour the epoxy resin on the tumbler. You can use your gloved hand or a soft brush to spread the epoxy on the tumbler evenly.
Once you are happy with what you’ve done, leave the tumbler spinner on for another 5 – 10 minutes. Once the epoxy resin has dried enough, take it off and remove the tape that you had put around the edges of the tumbler.
This is because you don’t want the resin to dry over the tape and get the tape stuck. After this, you can return the tumbler to the spinner and let it slowly spin for about 6 – 8 hours.
Materials to Use for Epoxy Tumblers
So, what are the best materials to use? We’ll look at the various types of tumblers and why they are good or not good for epoxy.
1. Metal Tumblers
Stainless steel tumblers are the number one tumblers to use when you want to add a glossy look to your tumbler. Why? Because epoxy resin adheres very well to the metal surface.
Also, you can choose to add a paint base coat if you want to change the color you’re working with. Good spray paint should do well.
Another reason why metal tumblers are loved is that you can use your smoothly finished glossy tumbler for both cold and hot drinks.
2. Glass or Ceramic Tumblers
The good news is that you can use ceramic or glass tumblers with epoxy. However, unlike with stainless steel tumblers, you can’t use them with hot liquids; only cold liquids.
The reason you can’t use them with hot liquids is that the ceramic or glass will absorb the heat and cause the epoxy to become soft. This will ruin your tumbler and negate all your hard work. If you really want a glass tumbler, consider getting one that has stainless steel on the outside.
3. Plastic Tumblers
Unfortunately, plastic tumblers are not the greatest option when it comes to epoxy tumblers. This is because the epoxy resin doesn’t adhere well to the plastic surface. It will peel off before you know it.
Nonetheless, if you truly want to make your plastic tumbler glossy, you can spray compatible paint on the plastic surface before applying the epoxy resin. This will give your epoxy resin a compatible surface to cling to.
Final Thoughts
For a 20 oz tumbler, you’ll need about 10 ml of epoxy resin. Remember to choose the right epoxy resin for tumblers as not all epoxy resins are suitable for this work.
Measure the A-side epoxy resin and the B-side epoxy resin into different measuring cups and mix them up in a clean measuring cup. We hope that this guide gave you insight into the right measurements to use when dealing with epoxy and how to mix and apply properly to avoid issues like your epoxy separating from your tumbler, etc.
