The Heat Guns That ELIMINATE Resin Bubbles!
When working with resin, one of the best resin tools you will want to get is a heat gun. A good heat gun will smooth out your surface bubbles and will pop any micro bubbles that want to float to the top.
Without a heat gun, epoxy resin won't get that mirror-like glass finish that you see on table tops or those gorgeous epoxy countertops.
There is often a lot of chat in the epoxy resin community over using a heat gun on resin or a torch.
We recommend using a heat gun over a propane torch to get your air bubbles out of your epoxy resin for the following reasons:
- You can control the temperature setting of your heat gun
- You get a more consistent temperature
- There is a more consistent hot air flow
- It is much harder to burn your resin
- It is safer to use
Many beginner resin artists are apprehensive with using heat guns on their resin, but quickly learn it is one of the most essential finishing tools. There is even the option of finding a mini heat gun as well.
How are heat guns used on epoxy resin?
Heat guns are very useful when making resin art. Whether you are creating resin jewelry, resin painting, geode resin art, epoxy glitter tumblers, coasters or more, these are the best tools to always have on hand to remove bubbles from your resin.
Heat guns are also amazing tools to push the flow of your resin around. They make great lacing cells in resin if you are into those beautiful beachy scenes where the white crest of the waves float over the dark blue resin oceans. This is achieved with the help of a great heat gun.
Do you need a heat gun to cure resin?
No, a heat gun is not necessary to cure the resin, yet in saying that, the heat gun will affect the overall outcome of your resin cure.
Without a heat gun, your resin may release microbubbles, which will slowly float to the surface during the curing process only to leave little dimples in your finished work and possibly throughout as they get caught in the curing resin, leaving you without that crystal clear look.

Can I use a hair dryer in place of a heat gun for epoxy resin?
Technically, yes you could use a hair dryer in place of a heat gun on your resin, but it will not get you the results that you want (and that you deserve after all that work!).
It is highly recommended that instead of using a hair dryer to get bubbles out of resin, you purchase a heat gun specifically for your resin bubbles. It works perfectly for this.
A heat gun is a good tool that will have a more controlled stream of air as well as heat. It will also be more concentrated and will fit better in your hands so you can target exactly where you want your resin to move.
What is the best heat gun for resin?
The best heat gun for resin will offer a continuous flow of controlled air, will offer different settings (heat or power settings) and will have a high enough temperature rating to pop resin bubbles.
There are many variables to determine what makes the best heat gun for poring resin and your other epoxy art. When looking at all of the heat guns available, we kept in mind:
- Temperature settings control ability
- Weight of the heat gun
- How easy it is to use and set up
- The customer ratings and reviews of it
- Our own personal experience with resin
It is important to get those bubbles out of the resin before it cures with a good heat gun, and we are going to share with you how we do just that. Just make sure you are working safely with resin before starting, and then you can get started on your project.
Here are the best rated heat gun choices for resin!
Best Heat Gun For Resin

This is a heat gun we highly recommend, and it is the best heat gun for the money. It is especially great for small epoxy resin projects such as resin jewelry, resin coasters and small resin molds.
2. Chandler Tool Heat Gun (more advanced option)
Here is a top rated heat gun for your resin crafts.
Another option for a heat gun is the Chandler Heat Gun. This is a great option for resin as it has a variable heat setting and speed setting, so having that extra control is great when you need a certain amount of heat or flow.
It is insulated, ergonomic, lightweight and is UL-certified. So it is more advanced in terms of the functionality of it, but is just as easy to use as the previously mentioned craft heat gun.
This is a great option if you are making many resin pieces or are casting into deeper molds. It is also a good option if you like to work on details (ie: beaches and waves in your resin) as it has the variable heat setting temperature range to control those waves. We call this a dual temperature heat gun and it will perform beautifully.
When looking at heat guns, this is an option that has everything you want in it to get a super clear resin surface. Plus you can choose between the blue or the pink option. This would be your best value heat gun choice.

Whichever heat gun you choose for removing bubbles from resin, there are also some things you need to remember for keeping annoying bubbles out of your resin before you get to the heat gun stage, and these include:
Stir Resin Gently To Avoid Bubbles
There are many brands of resin out there and they all have different mixing ratios. However, it is the mixing of the resin with the hardener that often creates bubbles.
You will want to stir the resin slowly. It will take longer because you want the resin and hardener to be well-mixed, but if you start off your project with the intention of keeping bubbles at bay, you will be less likely to have to get the bubbles out of your poured resin project.
You can also invest in a bubble removal machine, which is something brand new to the resin market!
Room temperature affects bubbles in resin
The temperature of your area plays a big role in resin art. For those of you who are working with your resin outside for safety reasons, this is something to keep in mind. Resin is happiest at around 75 F.
Pour resin in no more than 1/8" layers
If you are making a piece of art that has thick resin, pour it in layers and let cure in between these layers.
You won’t want to fill more than 1/8” deep at a time unless otherwise stated on the resin bottle you are using.
Pour resin close to your surface
When you are pouring your resin, make sure you are pouring as close to the surface or mold as possible, and do so slowly. You want to eliminate every chance for air to get into the resin.
Dry your inclusions thoroughly before embedding into resin
There are many beautiful things you can place in your resin pour. Popular choices include leaves, flowers and bugs. You will want to make sure your specimen is completely dry before embedding it in your resin though.
If your organic matter is not completely dried, it will continue to decompose within your resin and release bubbles.
Seal inclusions that may release air
If your inclusions are of a, organic, decomposable nature (flowers, herbs, wood), they may release air bubbles. Seal them before setting into your resin. You could use a paintbrush to paint a thin layer of mixed resin onto your items to be included in your art and let it cure.
Then you can pour your resin on top and use your heat gun to get bubbles out without worrying about your dried inclusion decomposing in your epoxy.
You could alternatively spray it with a spray sealer before setting it into your resin as well.
Invest in a pressure pot or bubble remover machine
Yes! These exist and do a seriously fantastic job at giving you crystal clear results. And there are larger industrial options, as well as nice countertop versions that would look great in any resin studio or workspace.

What to do if a cured resin piece has bubbles?
If you find that your resin piece has already cured and has bubbles in it, you can sand the surface of your resin with a very fine sandpaper and re-pour another layer of resin. Just remember, a respirator mask is highly recommended with both resin mixing and with sanding.
Unfortunately, you can't get out any bubbles that are trapped deep within the pour.
Heat guns are one of the best tools you can have as a resin artist, plus they are also a versatile tool as you can use them for so many other purposes other than pouring resin including transferring decoupage, for embossing, on heat transfer vinyl and more.

Here are some questions people also ask about heat guns and resin:
What type of heat gun do I need for resin?
When working with epoxy resin, it's best to use a heat gun with adjustable temperature settings. Look for one that can provide relatively low heat, starting at around 100°F (37°C), and can go up to about 350°F (177°C). This range gives you the flexibility to apply just the right amount of heat to your resin without the risk of overheating or causing bubbles.
Additionally, a heat gun with adjustable airflow is helpful for creating an even distribution of heat, preventing any uneven spots on your resin projects.
Can I use a heat gun instead of a torch for resin?
When it comes to working with resin, you can totally use a heat gun as an alternative to a torch. A heat gun offers several advantages, such as adjustable temperature settings and controllable airflow. This allows for more precise control over the heat application, helping to eliminate bubbles and create a smooth, even surface.
While torches are commonly used for resin, a heat gun can be a safer and more user-friendly option, especially for beginners.
Can I use a lighter instead of a torch for resin?
Using a lighter as a substitute for a torch in resin work is not recommended. Lighter flames are not directional and you will most likely burn your resin art or your fingers!
Lighters typically don't provide the controlled and evenly distributed heat needed for resin projects. Torches or heat guns are preferred because they emit a concentrated, high-temperature flame that can quickly eliminate bubbles and create a smooth surface. Plus they are much easier to control to get the results you want.
How long after pouring resin can you use a heat gun?
In general, it's best to start using a heat gun on your freshly poured resin within the first 20 to 30 minutes after pouring. During this initial period, the resin is in a liquid state and is most responsive to heat manipulation, which is best for getting rid of those bubbles and achieving a smoother surface.
Can I use a hair dryer instead of a heat gun for resin art?
This is a question that I really don't love to answer, because, yes, you can use a hair dryer instead of a heat gun for resin art *technically* to some extent.
However, keep in mind that hair dryers do not have that same concentration of heat, they may not offer the same level of temperature and airflow control as heat guns, and results may vary depending on your specific project.
You will most likely end up blowing your resin around in a way that alters the outcome, and honestly, some bubbles can be removed this way but all of them, most likely, won't. So, please be cautious with this answer.
