We all know the feeling of dread when we see a container full of burnt epoxy resin. And it’s not just a bad day for you, but also for your customers that need to purchase materials from you.
Luckily, there are some simple steps that can be taken to fix this problem and get back on track with making money!
In this article, we discuss what causes burnt epoxy resin and how to take care of it so as not to lose any more revenue.
How Do You Fix Scorched Resin
First, sand the burned area with fine-grit sandpaper.
Next mix equal parts of resin and hardener together to fill in gaps. You can either use this mixture or start over again from scratch if you need to do that as well! Let it dry and then sand smooth. Then continue on your way painting away!
Another option is to use a product called “Resin Infusion”. It’s essentially the same thing as mixing resin and hardener, but it’s already premixed.
Just brush or pour it over the scorched area, let dry until tacky (about 30 minutes), sand smooth with fine-grit sandpaper then continue on your way painting away!
Note: if you’re using Resin Infusion there are many different brands that work well for this application, however, some users have noted that Envirotex Lite doesn’t do quite enough of the restoring itself so they needed to follow up with their own mixture afterward.

What Happens If You Burn Epoxy
If you burn the epoxy, not only does it smell terrible but when you try to mix in your catalyst or hardener it is going to be a mess and take longer than necessary.
It’s important to get started on this process right away so that nothing gets ruined and wasted!
What Happens If You Overheat Resin
If you overheat resin, the epoxy polymer chains will cross-link and become hard. This change in chemical structure can be reversed by applying heat to soften or melt the hardened resins.
The best way to do this is by using a heat lamp, as it will evenly distribute the heat and provide direct access to those hard-to-reach areas.
How Do You Fix Yellow Resin
Burnt resin has a yellow tint to it. Yellow can indicate that the epoxy is contaminated with oils or chemicals, but more often it’s just because of exposure to ultraviolet light.
If you are new at casting then this will be your first obstacle in resining and pouring your piece.
Most likely some batches of resin were exposed too long to UV lights while curing on their way from China (or wherever they come from).
When people complain about the color-changing I usually assume it’s not due to contamination but rather simply leaving them out under fluorescent lights for days after being poured.
Can You Fix Burnt Epoxy
In short, yes you can fix burnt epoxy. However, sometimes it is easier said than done because the process depends on how badly your project has been damaged and what caused the burn in the first place.
Can You Burn Epoxy With Heat Gun
Of course, you can burn epoxy with a heat gun. When heating up resin, your best bet is to keep the temperature low and work in small increments.
You should also make sure that you are using a heat gun that has an adjustable speed setting or one that goes from cool to hot gradually because if it goes straight from cold to super-hot, chances are good this will result in your burning epoxy resin.
How Do You Burn Off Epoxy
If you’ve ever tried to cure epoxy resin with a butane torch, this article will help you understand why it’s such a bad idea and what you can do instead. It’ll also teach you how to fix burnt or scorched pieces of your work that house the burned-off epoxy within them.
If all else fails, there are some things that might salvage your project if it has been badly scorched by an open flame.
Can You Overheat Resin
Yes, you can overheat resin. Resin is plastic and therefore has its melting point as well as burning points. Resin can burn and combust when heated to a certain point.
Why Did My Epoxy Resin Get Hot
Your epoxy resin got hot due to a chemical reaction. When you mix the two parts of the kit together, heat is produced as they combine with one another and cure into a solid.
Mixing slowly will help reduce this process and prevent it from getting too warm but if the temperature gets high enough, your cured resin can be damaged or even ruined!
Why Did My Epoxy Resin Crack
Epoxy resin is a polymer with two parts, so it’s important to mix them well before use.
If they are not mixed evenly or thoroughly enough the epoxy will have an uneven curing time and therefore develop stress cracks over time.
This can be caused by using too much hardener in relation to the amount of base but also from using old material that has started to cure even though you may not see any change color-wise.
How To Fix Epoxy Mistakes
If you have a resin epoxy mistake that has caused your product to become foggy, there is no need to panic.
This issue can be easily solved by using an adhesive filler and applying it on top of the damaged area until smooth.
Wait for the compound to dry completely before sanding off residues (220). After doing this, apply paint if needed and then use paste wax as described in step two above!
There are many ways that wood filler can save the day! You will find below five methods that work very well when repairing cracks or scratches with this material:
mix some color pigments into the wood filler mixture so that it becomes darker than its original tone after drying up.
Then, apply it to your resin epoxy mistake and wait for the compound to dry completely before sanding off residues.
After this, you will have a lighter color in comparison with the surrounding area which can be easily fixed by applying paint over it!
if you want a better result when repairing cracks or scratches, mix some white pigment into wood filler instead of using colored pigments.
Apply it on top of the damaged area until smooth after waiting for all previous layers to dry up thoroughly.
Then use fine grit paper (220) as well as paste wax as described above so that your product shines again like new!
if you would rather not change the original tone scratch repairs but still do them to be more durable and long-lasting, apply a coat of paint over the area that has been repaired with wood filler after you have sanded off all residues.
This method works well when it comes to restoring large areas such as your furniture’s top layer!
another way to repair resin epoxy mistakes is by using drywall compound instead of wood fillers or paints but this material does not work well for small damage spots because it dries too quickly.
if your mistake involves cracks in an otherwise smooth surface, use special crack repair products available on the market today so they perfectly match the original tone and texture.
These materials are easy to handle and their consistency allows them to spread out evenly.
