Epoxy is often used for a variety of applications because it is strong and durable. However, epoxy can sometimes form fisheyes.
What are fisheyes, and why do they form? This blog post will answer those questions and provide tips on how to prevent them from forming in the first place.
How do you fix fisheye in epoxy?
If you’re asking yourself this question, then chances are you’ve already run into the problem of fisheye in your epoxy resin.
Fisheye is caused by contaminants in the resin, and it results in small craters or divots in the surface of the cured resin.
There are a few ways to fix fisheye in epoxy, but the most common method is to simply sand it down and start again.
You can also try using a heat gun to smooth out the surface, but this can be tricky and may not always work.

How do you fix dimples in epoxy?
One way to fix dimples in epoxy is to use a vacuum degasser. This will remove any entrapped air bubbles and help to level out the surface of your epoxy.
Another way to fix dimples is to use a heat gun or hair dryer on low heat. This will help to pop any remaining air bubbles and smooth out the surface of your epoxy.
Finally, you can try using a chemical releasing agent such as silicone oil or WD-40.
This will help to release any trapped air bubbles and allow them to escape from your epoxy surface.
How do you fix fisheye?
There are a few ways that you can fix fisheye in your epoxy. The first way is to mix the epoxy slowly and thoroughly.
If you don’t mix the epoxy properly, it will create air bubbles which will cause fisheye.
Another way to fix fisheye is to use a defoamer. A defoamer is a product that you add to the epoxy to help prevent air bubbles from forming.
How do you prevent fisheye in epoxy?
Preventing fisheye in epoxy is a matter of understanding what causes it and then taking steps to avoid those conditions.
Fisheye is caused by one or more of the following:
– Incompatible materials
– Poor surface preparation
– Improper mixing
How do you fix pits in resin?
If you find pits or bubbles in your resin, there are a few ways to fix them. You can sand the area down and start again, or you can use a product like Epoxy Putty to fill in the imperfections.
Once the area is smooth, you can continue with your project. If you have large areas of fisheye, you may need to start over with a new batch of resin.
Can you spot fix epoxy?
Unfortunately, you can’t really spot fix epoxy. If there is a fisheye in your epoxy, it means that there was likely an impurity on the surface that the epoxy came into contact with.
The best way to avoid this is to make sure that your surfaces are clean and free of any contaminants before you start your project.
Why is my epoxy rippling?
Rippling can be caused by many things- the temperature of your work area, humidity in the air, even the oils from your skin can affect how well your epoxy flows.
If you notice ripples appearing in your cured epoxy, it’s likely due to one of these three factors.
How do you prevent pits in resin?
Pits can be caused by a number of things, but the most common cause is dust or debris on your work surface.
Make sure you’re working in a clean environment, and if possible, use a vacuum cleaner to remove any dust before you start mixing your epoxy.
Another common cause of pits is using too much hardener. When you mix your epoxy according to the manufacturer’s instructions, they’ll give you a range for how much hardener to use.
If you use too much hardener, it can cause the epoxy to cure too quickly and create pits on the surface.
What is a fisheye eliminator?
Fisheye eliminator is an additive that you can mix into your epoxy resin to help eliminate the fisheye effect.
How do you make a fisheye eliminator?
There are a few ways to make a fisheye eliminator. One way is to use a product called Fisheye Fixer.
This product is applied to the surface of the epoxy before it cures and creates a barrier that prevents the formation of fisheyes.
Another way to prevent fisheyes is to mix the epoxy slowly and carefully. If you pour the epoxy too quickly or stir it too vigorously, air bubbles can form and cause fisheyes. So take your time and be gentle when mixing the epoxy.
How do you fix fisheye on polyurethane?
One way to fix fisheye on polyurethane is by adding a wetting agent. Wetting agents help break the surface tension of the liquid, allowing it to spread evenly and eliminating fisheye.
You can also try using a de-foamer or anti-foaming agent. These work by breaking down the bubbles that cause fisheye, allowing the epoxy to flow evenly and without defects.
If you’re still having trouble, you can try thinning the epoxy with a solvent. This will make it easier for the epoxy to spread evenly and eliminate fisheye.
Should you sand between coats of epoxy?
The short answer is yes, you should sand between coats of epoxy. The long answer is a little more complicated.
There are a few reasons why you might want to sand between coats of epoxy. The first reason is that it will help to create a smooth surface.
If you don’t sand between coats, the surface of your project will be bumpy and uneven.
The second reason is that sanding will remove any dust or debris that might be on the surface of your project.
This is important because if there is dirt or dust on the surface, it can cause the epoxy to develop fisheyes.
