3 Best Heat Guns For Resin and Resin Bubbles [2022]

When working with resin, one of the best resin tools you will want to get is a heat gun. A heat gun for resin will smooth out your resin surface and will pop any micro bubbles that want to float to the top. Without a heat gun, resin art won't get that mirror-like glass finish.

Can you use a heat gun on resin?

Heat guns are very useful when making resin art. Whether you are creating resin jewelry, geode resin art, tumblers, coasters or more, heat guns are a beneficial tool to always have on hand to pop those little resin bubbles.

Heat guns are also amazing tools to push the flow of your resin around. Heat guns make great 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 heat gun for resin.

Do you need a heat gun to cure resin?

No, a heat gun is not necessary to cure the resin per say, 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.

Can I use a hair dryer in place of a heat gun for resin?

Technically, yes you could use a hair dryer in place of a heat gun for resin. It is highly recommended that instead, you purchase a heat gun specifically for your resin bubbles. A heat gun 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.

Whichever heat gun you choose for resin, there are also some things you need to remember for keeping 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.

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 In 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 decomposable nature, 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 item to be included in your art and let it cure. You could alternatively spray it with a spray sealer before setting it into your resin as well.

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.


No matter what type of resin you decide to use, always use PPE. Do take time to carefully go over safety data sheets before making anything with resin. And it's very important to follow the instructions on the resin.
