How to get bubbles out of resin

One thing we absolutely love working with here at DIY Craft Club, is resin. In fact, we have made some of our favorite pieces using epoxy resin! But there is one thing that can ruin a piece that you have created. And that is finding bubbles in your resin, or small holes where bubbles rose to the surface during resin curing where they popped, leaving divets in your beautiful resin work.

It is important to get those bubbles out of the resin before it cures, and we are going to share with you how we do just that.

Here's How To Get Bubbles Out Of Resin

There are many ways to get bubbles out of resin. We'll show you how, using different techniques, methods, and tools. Here are our top choices on how to get bubbles out of your epoxy resin pours and creations.

1. Carefully Stir To Avoid Bubbles In Resin

There are many brands of resin out there and they all have different mixing ratios. However, it is the stirring of the resin, once mixed with the hardener, that can often create bubbles if care is not taken.

You will want to mix the resin slowly, like you are folding egg whites into a cake. It will take longer because you want the resin and hardener to be well-mixed, but if you start off your project with care you will be less likely to have to get the bubbles out of your poured resin project.

2. Room Temperature Affects Bubbles In Resin

Temperature 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 degrees Fahrenheit. This information is very relevant when it comes to how your resin is curing, but also affects the bubbles that rise to the surface during that curing time.

3. Pour In 1/8" Resin Layers

If you are making a piece of art that has thick resin, pour in layers. You won’t want to fill more than 1/8” deep at a time. And when you are pouring, 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.

4. Completely Dry Inclusions In Resin To Avoid Surprise Bubbles

There are many beautiful things you can encase in resin. Some popular choices include dry leaves, dried flowers, and even bugs and butterfly wings! You will want to make sure your specimen is completely dry before including it in your piece though. If your organic matter is not completely dried, it will continue to decompose within your resin and release bubbles.

We have our very own article titled How To Dry Flowers detailing some really great methods for drying flowers that you should check out!

5. Seal Inclusions In Resin That May Release Air Bubbles

If your inclusions are of a material that 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.

6. Use A Heat Gun To Eliminate Bubbles

I love my Zap heat gun. This is what I personally like to use when clearing the bubbles from my resin layers after my pour. And it is so satisfying to watch them pop haha. If you are pouring resin in layers, you will want to use the heat gun for each layer. The heat allows the resin consistency to become more fluid so the bubbles are able to escape to the surface and pop. You can grab yourself a Zap heat gun on Amazon here.

You can also compare the Zap heat gun with other heat guns prices. Here is a selection of different heat guns for price comparison on Amazon right here for you.

7. Use A Flame Torch To Pop Bubbles In Resin

A torch provides a higher level of heat than a heat gun can and many resin artists prefer using a torch over a heat gun for that reason. However, there is some discussion in the resin community for those artists who like to color their resin with alcohol ink. Alcohol is flammable, but there is such a small amount of alcohol ink required to color resin with. So it is just something to keep in mind.

I personally have found that the torch that comes in a creme brulee kit is just PERFECT for this job!!! I've used the big propane torches you can get at your local hardware store, you know, those green 1lb ones, but they are just heavy and bulky. The creme brulee torch is small, allowing you to work on the details and get those little bubbles out.

The exact set I have is from Bed Bath & Beyond, but I found the exact same one (for much cheaper) on Amazon, which you can check out right here.

How Do I Fix My Piece Now That It's Dried And Has Bubbles?

If you find that your resin piece has already cured and has bubbles in it, you can sand down the surface of the resin with fine sandpaper and re-pour another layer of resin.

It's important to make sure that the whole resin surface is lightly sanded because you need to provide some tooth so that the resin layers can adhere properly.

Unfortunately, you can't get out any bubbles that are trapped deep within the pour.
