You’ve finished your epoxy sculpture or resin tumbler. And you’re ecstatic – until you notice the surface is uneven. The service has dimples if you look closely. These resin dimples, also known as divots, holes, voids, and fish eyes, don’t have to ruin your project.

Surface tension will be disrupted by contaminants on the substrate, causing the epoxy to split or pit. Continue reading to get rid of fish eyes in epoxy countertops:

What Are The Main Reasons For Fish Eyes In Epoxy?

Dents in your epoxy countertop can happen in two ways. The first is dents or divots in the otherwise glossy smooth surface shortly after the epoxy has been poured. A soft countertop with indentations from any heavy item is the second scenario.

So, why would the epoxy dimple be like this since it is intended to be a long-lasting and resilient surface? There are particular reasons for either of these issues with your countertop.

Fish Eyes Occur Because Of Lack Of Product:

When pouring epoxy onto a countertop or tabletop, you may see divots appearing on the surface for various reasons. A fisheye is a low place in an otherwise smooth tabletop.

When you don’t have enough merchandise, this is the most prevalent cause of these issues. If you don’t use enough product, it will create gaps at some points, resulting in a fisheye effect.

Alcohol Spray On The Surface Causes Fish Eyes:

Another explanation for fisheyes in your wet epoxy is attempting to spray the alcohol over the surface after it has started to cure up. The epoxy does not self-level once it begins to harden due to the weight of the alcohol. Spray your colors while the epoxy is still wet to circumvent this problem.

Silicone Coating On The Surface Also Causes Fish Eyes:

If you have silicone on the countertop surface, you may have fisheyes in your recently poured countertop. The epoxy won’t stick to the silicone and will bead up on the surface. To avoid this, make sure all silicone is removed from the surface before pouring the epoxy.

To fix this, wait for one day after the first coat has dried before sanding the silicone away and pouring a second coat.

Ways To Fix The Fish Eyes In Epoxy Countertops:

Work with epoxy in a clean, well-ventilated environment with little airflow to avoid introducing pollutants to your work area.

Wipe the substrate with Denatured Alcohol on a lint-free rag to remove the majority of impurities and oils that may be present. Before applying an epoxy seal coat, let the alcohol vanish completely.

1)Find Out The Accurate Reason For Fish Eyes:

You’re more likely to make them again if you don’t know why they happened. Make sure you understand what happened to avoid them in the future. Keep the workpiece and epoxy resin at the same temperature to minimize thermal shock and the resin swiftly shrinking and orange peeling. When hot resin comes into contact with a hard substrate, the temperature rapidly changes, causing the resin to ripple and stop flowing properly.

2)Figure Out The Depth Of Fish Eyes:

Mix and pour a new flood coat of resin into the divots. Make sure your resin surface is clean, and you’re using the proper amount of doming resin. These resins are made to self-level and coat a surface equally.

If your holes are small, they will evenly spread throughout the entire surface. This resin calculator will perform the math for you if you don’t know how much epoxy you’ll need. When learning how to mend dimples, it’s critical to utilize good epoxy glue.

3)Avoid Touching The Wet Coating Of Epoxy:

Take a break from it and return in about a half hour to check for any discrepancies in the coating. Even walking around the workpiece might kick up dust and particles, causing a pinhole or fish eye in your epoxy seal layer. Allow the resin to flow and flatten for a few minutes.

4)Use Sanding Resin For Multiple Eyes:

You’ll have to sand the epoxy resin surface to make the dents shallower because doming resin prefers to level to one-eighth of an inch. The resin will cover the surface uniformly when you apply another flood layer.

It’s possible that when pouring the second layer of resin, it won’t fill to the edge and the first. To ensure that the resin reaches the edge, use masking or painter’s tape to construct a tape dam around the sculpture.

5)Avoid Brushing Inconsistent Areas:

Brushing over irregular epoxy seal coat regions will likely reduce surface tension, resulting in a larger fish eye or separation. All you need is a dribble of more epoxy on the affected region to solve the problem.


Hopefully, you won’t have to worry about how to correct dimples in epoxy by the time your resin dries the next time. Above all, the environment in which you work and your preparation efforts are factors in applying epoxy resin seal coats properly. The smoothness, gloss, and homogeneity will be substantially improved if you follow the instructions above.
