Can You Fix Yellowing Epoxy?

In the world of DIY, there are a lot of new products that seem to have a short shelf life. And when you’re dealing with something as finicky as epoxy, those frustrations can start to add up pretty fast. Thankfully, the yellowing process isn’t an irreversible one with most epoxies.

With some quick work and simple solutions, you can get your epoxy back to its original color in no time at all. So let’s take a look at how we can fix your epoxy that has become yellow…

What Causes Epoxy to Turn Yellow?

There are a few reasons why your epoxy may turn yellow.

The first one is oxidation. The chemical reaction between the epoxy and the oxygen in the air causes it to turn yellow. There are a few ways to slow this down, and we’ll dive into that later.

The second reason is that the epoxy may have been tinted yellow to begin with. Many epoxy products are tinted yellow to help you see where you’ve applied it, so if you’re applying it to your wood and it turns yellow, then that’s normal.

How to Fix Your Epoxy

There are a few ways to fix your epoxy that has become yellow.

First off, you can use a covering agent or a covering coat. Sounds fancy, but it’s actually pretty simple. All you need to do is mix up some epoxy and add some black pigment to it. You can then paint this mixture on top of your yellowed epoxy and let it dry. When it dries, you’ll have your original color back with a fresh protective coating.

Another option is to mix up your epoxy with some white pigment. You won’t need much for this, just a little bit will do the trick. If you’re dealing with a dark grey epoxy, then you’ll need more white pigment than if you’re dealing with yellow epoxy. This will both cover up your yellowed epoxy and lighten it at the same time. It’s the perfect two-for-one solution!

How to Lighten Your Epoxy

If you have yellowed epoxy, but you don’t want to cover it up with a different color, you can also lighten it. For this, you’ll first want to clean your epoxy. You can do this with a simple vinegar and water solution, or you can use a citrus cleaner. Once your epoxy is clean, you’ll want to mix it with some hydrogen peroxide. You’ll want to mix it well and apply it to your epoxy. Let it sit for a few hours, then rinse it off and you should be good to go.

How to Bleach Your Epoxy

If you have a dark grey epoxy and don’t want to lighten it, then you can bleach it. Start off by cleaning your epoxy with a vinegar and water solution. Once it’s clean, mix in some hydrogen peroxide. You’ll want to mix it well, so you get a nice, even consistency. You’ll want to let it sit for a few hours, then rinse it off with water. It’s important to use warm water while rinsing. Cold water will cause the hydrogen peroxide to sit in the epoxy longer and make it more difficult to remove.

How to Fix Dark Grey Epoxy

If your epoxy is already dark grey, then you’ll have to bleach it before you can lighten it. You can do both of these methods at the same time if you’d like. First, clean your epoxy with a vinegar and water solution. Once it’s clean, mix in some hydrogen peroxide. Let it sit for a few hours, then rinse with warm water. Once your epoxy is clean, you can then add white pigment to lighten it. Mix it well and let it dry.

Which Brands Are Most Susceptible to Turning Yellow?

It’s hard to say which brands are most susceptible to turning yellow because it’s such a subjective thing. However, there are a few brands that seem to pop up more often than others. Epoxies like Gorilla Epoxy, Loctite Epoxy, and Versa Bond are very popular among DIYers. They’re also some of the most susceptible to turning yellow. If you’re using one of these brands, follow the instructions carefully and use them as soon as you can. This will help you minimize the amount of oxidation that occurs.

Conclusion

Epoxy is a two-part adhesive that can be used to bond a variety of materials together. Epoxy is often used to fix items such as vases, figurines, and other decorative objects. However, epoxy can yellow over time, which can make the adhesive difficult to see and can also affect the appearance of the object being repaired.

Luckily, there are lots of ways to fix your epoxy that has become yellow. Whether you use a covering agent, mix in white pigment, lighten your epoxy, or bleach it, you can easily get your epoxy back to its original color in no time at all.
