All of us have been there. You applied a coat of epoxy resin and it turned out cloudy, milky, or clear like water with patches.
The last thing you want to do is spend more money on supplies, so we’ll show you how to fix cloudy epoxy resin!

Why Is My Epoxy Resin Cloudy
There are a few reasons why your epoxy resin may be cloudy. The most common reason is that the resin has not been mixed thoroughly. When the resin is not mixed properly, air bubbles can form and cause the resin to become cloudy. If this is the case, mix the resin thoroughly until it is clear and there are no more air bubbles present.
If your epoxy resin is cloudy due to contamination, you will need to clean it up before you can use it.
How Do You Clear Up Cloudy Resin
If your epoxy resin has become cloudy, there is a way to fix it. The first step is to identify the cause of the cloudiness. There are several reasons why epoxy resin can become cloudy, including:
- The presence of air bubbles
- Excessive heat
- Contamination by foreign particles
Once you have identified the cause of the cloudiness, you can take steps to correct it. If air bubbles are the problem, you can release them by popping them with a sharp object or using a vacuum cleaner. If heat is the issue, allow the resin to cool down. If contamination is causing the problem, remove the offending particles with a brush or tweezers.
Once you have addressed the root cause of the cloudiness, you can determine whether or not to use epoxy resin.
If your project does not require a clear finish and you just want something that is strong and durable, then an opaque finish might be acceptable.
On the other hand, if you really need a transparent look for your final product, consider using another type of adhesive such as silicone sealant instead.
How Do You Fix Epoxy That Didn’T Cure
If your epoxy resin didn’t cure, there are a few things you can do to try and fix it. First, check the temperature of the room where you were working. Epoxy cures best in temperatures between 70-80 degrees Fahrenheit.
If the room was too cold, that may be why your epoxy didn’t cure properly.
Another thing to check is the humidity level of the room. Epoxy resin doesn’t cure well if there is high humidity in the air.
Try increasing the airflow in the room or wait for a day when the humidity is lower to try again.
If neither of those things seems to be causing the problem, then it’s possible that you mixed your epoxy wrong. Make sure all of the resin is fully combined with all of the hardeners.
If you don’t mix them thoroughly, then your epoxy won’t cure properly.
If none of these seem to be causing the problem, it’s possible that something else was wrong with this batch of epoxy.
It could have been old or improperly stored before you bought it, for example. While most epoxies will last for years unopened if they are kept out of heat and light, once opened some resins may only keep their properties for a few months before going bad entirely.
In this case, try using another new bottle instead as a test first before trying again on your project in case there really isn’t anything you can do to salvage it.
Why Did My Epoxy Resin Turn White
There are a few possible reasons why your epoxy resin may have turned cloudy or white. One possibility is that the resin was not mixed thoroughly enough, causing air bubbles to form.
Another possibility is that the curing agent was not added in the correct ratio. If too much curing agent is used, it can cause the resin to harden prematurely and turn cloudy.
Finally, if the ambient temperature is too low, it can also cause the resin to turn cloudy.
If your epoxy resin has turned white, there are several things you can do to fix it:
Mix the resin thoroughly until there are no more air bubbles present. Make sure to use a stirring paddle that reaches all corners of the container.
Make sure that the curing agent was added in the correct ratio. If too much curing agent has been used, you will need to add a little bit of resin and stir thoroughly until there are no more air bubbles present.
Make sure that the ambient temperature is between 60 degrees Fahrenheit to 85 degrees Fahrenheit.
You may also want to place a heater or fan nearby if it’s very cold out so as not to overheat your epoxy resin mixture.
Why Is My Resin Not Glossy
One potential reason why your resin is not glossy is that it has been contaminated with another material.
In particular, if the resin is cloudy then it may be due to an air bubble or a particle of dust.
If this is the case, you can try to fix the problem by using a vacuum cleaner to remove any bubbles and then gently blowing on the surface of the resin to remove any particles.
If these methods do not work, you can try adding a small amount of acetone to the resin. Acetone will help to break down any contaminants and will make the resin more glossy.
However, be careful not to add too much acetone as this could cause other problems such as bubbling or distortion.
Finally, you can add more of the catalyst to your resin. However, this will not fix a problem with air bubbles or contamination, it may make your resin glossy but any contaminants within the mixture could still cause problems.
How Do You Restore Shine To Sanded Epoxy
If your epoxy resin has lost its shine after being sanded, you can restore it by using a polish or wax. Apply the polish or wax to a cloth and rub it into the surface of the resin until it is shiny. Make sure to clean off any excess polish or wax before it dries.
Can You Buff Resin
Yes, you can. Buffing resin doesn’t mean it will become clear again but the surface of your epoxy might look better after buffing.
You should know that if there are small bubbles embedded in your epoxy layer they won’t disappear when you try to polish them away, so this is not a magic trick either.
How Do You Fix Cloudy Epoxy After Sanding
If the resin is cloudy after sanding, you can try to clear it up by mixing in a little bit of epoxy thinner.
Be careful not to add too much, or the resin will be too thin and won’t harden properly.
You may also need to adjust the ratio of hardener to resin if the mixture is too thick.
If these measures don’t work, you can try heating up the resin until it becomes more transparent.
However, this method can be risky, so make sure you’re careful not to overheat the resin and damage it.
Finally, if all else fails, you can simply discard the cloudy resin and start over with a new batch.
Can You Polish Resin With Toothpaste
Polishing cloudy or scratched epoxy resin with toothpaste can help to restore its shine. Just make sure to use non-abrasive toothpaste and avoid getting the paste on the surrounding surfaces. Rub the toothpaste in a circular motion until the resin is clear and shiny. Then, buff it with a soft cloth.
How Do You Make White Milky Resin
Milky resin is generally caused by a reaction between the ingredients during curing, like an acid-base type of chemical reaction.
This can be prevented with proper storage and preparation methods to avoid bubbles or foam in your epoxy resin mixture.
The other cause could be that too much thickener was added into the mix which will prevent it from curing all the way.
In this case, you can add a little bit of solvent to thin it out and then recoat.
What Happens If You Add Too Much Hardener To Epoxy
Well, it can lead to a cloudy epoxy resin. In this case, there isn’t much you can do about the cloudiness, but if you know how to fix cloudy epoxy resin, your efforts won’t be in vain.
