Understanding Fish Eyes in Epoxy Tumblers
Have you ever experienced tiny craters popping up on your epoxy tumbler? This is commonly referred to as fish eyes. It can be frustrating, especially if you’ve put so much work into making your tumbler look perfect. Don’t worry, though, because there’s a fix for that! But before we dive into the solution, let’s first understand what causes fish eyes.
When applying epoxy on a tumbler, it’s essential to have a clean and dust-free surface. However, even with proper cleaning, you can still get fish eyes caused by surface contaminants you might have missed. Fish eyes result when the epoxy doesn’t wet out on the contaminated area, causing the epoxy to pull away, creating a crater-like appearance.
Small air bubbles trapped underneath the epoxy can also cause fish eyes. When mixing the epoxy, making sure it’s mixed thoroughly is critical to avoid trapping air bubbles. Another factor that can contribute to air bubbles is over-agitation of the mixture. Vigorously mixing the epoxy will only add more air into the mixture and create more bubbles, leading to more fish eyes.
Aside from air bubbles and surface contaminants, humidity can also cause fish eyes on your tumbler. When there is too much moisture in the air, it can create surface tension, and when the epoxy is applied, it does not fully wet out, creating fish eyes. It’s essential to check the weather before applying epoxy; if the humidity is high, wait for a drier day before starting your project.
Using epoxy that has either expired or not stored correctly can also cause fish eyes. Always check the expiration date before purchasing and using the epoxy. Also, store the epoxy in a cool, dry place, away from direct sunlight, to avoid contamination.
In conclusion, knowing what causes fish eyes is essential to prevent it from happening. Some tips to avoid fish eyes are to make sure the surface is free of contaminants and to mix the epoxy thoroughly while avoiding over-agitation. Checking the humidity level before applying epoxy and using fresh and correctly stored epoxy are vital to achieving a smooth finish.

How to Fix Small Fish Eyes in Epoxy Tumblers
Small fish eyes are the imperfections that can often appear on the surface of your epoxy tumblers. They are usually caused by air bubbles that get trapped in the epoxy during the curing process. They can be frustrating to deal with, but fortunately, there are a few methods you can use to fix them. In this article, we will go through some of these methods step-by-step.
Method 1: Sanding
Sanding is the easiest way to get rid of small fish eyes. Start by wet sanding the tumbler with a high-grit sandpaper. Make sure the sandpaper is wet, as this will help to prevent any dust or debris from getting into the epoxy. Sand the tumbler in a circular motion, applying gentle pressure. Do not apply too much pressure as this may cause the epoxy to heat up and melt.
After a few minutes of sanding, take a dry cloth and wipe the tumbler clean. You should notice that the fish eyes have disappeared, and the surface of the epoxy is smooth. Repeat the process if necessary, using a higher grit sandpaper.
It is important to note that sanding may leave scratches on the surface of the epoxy. You can use a polishing compound to remove these scratches and bring back the shine of the tumbler.
Method 2: Re-Coating
Re-coating is another method you can use to fix small fish eyes. Start by mixing a small amount of epoxy, just enough to cover the affected area. Brush the epoxy onto the fish eyes, making sure to coat them evenly. It is important to use a small brush to avoid applying too much epoxy, which could create more fish eyes.
After you have coated the fish eyes, wait for the epoxy to cure according to the manufacturer’s instructions. This usually takes around 24 hours. Once the epoxy has cured, sand the surface of the tumbler with a high-grit sandpaper, making sure to wet sand to avoid dust and debris. Wipe the tumbler dry with a cloth, and the fish eyes should be gone.
Method 3: Torch Method
The torch method is probably the most effective but also the most challenging method. It involves using a torch to apply heat to the surface of the epoxy, which helps to release any air bubbles trapped inside. However, it is important to be careful when using a torch, as it can cause the tumbler to melt or burn.
To use this method, start by heating the torch on a low setting. Hold the flame about an inch away from the surface of the epoxy, and move it back and forth over the affected area. You should notice that the fish eyes start to disappear as the heat releases the trapped air bubbles. Be careful not to overheat the epoxy, as this can cause it to melt. Once the fish eyes have disappeared, let the epoxy cool down before handling it.
It is important to note that the torch method may not be suitable for all types of epoxy or tumblers. Some epoxy may be too heat-sensitive, and some tumblers may be too delicate to withstand the heat from the torch.
In conclusion, fixing small fish eyes in epoxy tumblers is not impossible. With a bit of patience and the right methods, you can easily get rid of these imperfections and create a smooth, flawless surface for your tumbler.

Preventing Fish Eyes in Future Epoxy Tumbler Projects
Preventing fish eyes in your epoxy tumbler projects is easier said than done. But it’s not impossible. In fact, with a few simple strategies, you can dramatically reduce the likelihood of developing unsightly fish eyes in your epoxy tumbler projects.
Before we dive into how to prevent fish eyes, let’s review what they are. Fish eyes are small air pockets that get trapped in the epoxy coating during the curing process. They create a circular pattern on the surface of your tumbler and can be quite unsightly.
So, how do you prevent fish eyes? Here are five strategies:
Avoid Cold Surfaces
One of the main culprits of fish eyes in epoxy is a cold surface. When epoxy coating is applied to a cold surface, it can take longer to cure and will develop fish eyes. To prevent this, make sure your tumbler is at room temperature before you begin your epoxy coating application. If your workspace is cold, consider using a space heater or warming your tumbler in the oven before you begin.
Use a Sealant
One way to help prevent fish eyes is to use a sealant before applying epoxy. A sealant will help fill in any micro-cracks or pores in your tumbler’s surface, which can create pockets for air to get trapped. Use a sealant that is compatible with your epoxy and follow the manufacturer’s instructions carefully.
Another common cause of fish eyes is improper mixing of the epoxy. If you don’t stir thoroughly, you can create air pockets that will show up as fish eyes. To prevent this, make sure you follow the manufacturer’s instructions for mixing your epoxy. Use a stir stick or a drill mixer to stir the epoxy until it is fully blended, and make sure to scrape the sides and bottom of the mixing container as you go.
Apply Epoxy in Thin Layers
Another way to prevent fish eyes is to apply your epoxy coating in thin layers. Thick layers of epoxy are more likely to trap air pockets as they cure. Applying your epoxy in thin, even layers will give it more time to self-level and release any air pockets before curing.
Use a Torch
Finally, a useful strategy to prevent fish eyes is to use a torch to remove air bubbles as your epoxy cures. A butane torch is precise, easy to use, and heats up the epoxy just enough to release any trapped air pockets. All you need to do is gently pass the torch over the surface of your tumbler as the epoxy cures, and watch the fish eyes disappear!
With these simple strategies, you can prevent fish eyes in your epoxy tumbler projects and ensure a beautiful, smooth finish every time. Remember to take your time, be patient, follow the manufacturer’s instructions, and use high-quality materials to achieve the best results. Happy crafting!
