Removing Bubbles From Resin: A Bubbly Guide
Are you tired of those pesky little air bubbles ruining your gorgeous resin projects? Fear not, for I'm here to share some tried-and-tested tips and tricks to help you achieve a bubble-free, crystal-clear finish every time.
Before we dive into the nitty-gritty details, let's set the scene. You've meticulously mixed your resin, poured it into your mould or onto your surface, and you're eagerly awaiting the final result. But alas, those dreaded bubbles start appearing, threatening to turn your masterpiece into a bubbly mess.
Bubbles are a common occurrence when working with resin, but with the right techniques, you can bid them farewell and embrace a bubble-free existence. So, let's explore the various methods of removing bubbles from art resin.
The Trusty Lighter Method
This tried-and-true method is a favourite among resin enthusiasts, and for good reason. All you need is a long-necked lighter, and you're ready to go.
Here's how it works:
Once you've poured your resin, gently pass the flame over the surface, keeping a safe distance to avoid scorching.
The heat from the lighter will cause the bubbles to rise and pop, leaving you with a smooth, bubble-free finish.
Be careful not to hold the flame in one spot for too long, as this can create new bubbles or cause the resin to cure unevenly.
The Tap, Tap, Tap Technique
If you don't have a lighter handy or prefer a more low-tech approach, the tap, tap, tap technique might be right up your alley.
Here's how to master it:
After pouring your resin, gently tap the sides of your mould. You can use a wooden stick, a rubber mallet, or even your trusty knuckles (just be gentle).
The tapping motion will help dislodge any stubborn bubbles, allowing them to rise to the surface and pop.
For best results, tap in a circular motion, working your way from the centre outwards.
Pro Tip: Don't go too hard with the tapping. Too much force can create new bubbles or cause your resin to spill over the edges. A light, rhythmic tap is the way to go.
Pressure Pot
If you're a serious resin aficionado or working on larger projects, investing in a pressure pot might be worth considering. These nifty little devices use compressed air to force the bubbles out of your resin, resulting in a flawless, professional-grade finish.
Here's how it works:
Place your resin-filled mould or surface inside the pressure pot.
Seal the pot and slowly increase the pressure, following the manufacturer's instructions.
The increased air pressure will cause the bubbles to shrink and eventually disappear.
Once the desired pressure is reached, maintain it for a specified amount of time, then slowly release the pressure.
Pro Tip: While pressure pots can be a game-changer, they do require some safety precautions and a bit of practice. Make sure to read the instructions carefully and never exceed the recommended pressure levels.
Vacuum Chamber
Similar to the pressure pot, a vacuum chamber is another heavy-duty solution for those serious about achieving a bubble-free resin finish. This method involves placing your resin-filled mould or surface inside a chamber and creating a vacuum environment.
Here's how it works:
Place your resin-filled mould or surface inside the vacuum chamber.
Seal the chamber and turn on the vacuum pump, creating a low-pressure environment.
The reduced air pressure will cause the bubbles to expand and rise to the surface, where they can easily pop or be removed.
Maintain the vacuum for a specified amount of time, then slowly release the pressure.
Pro Tip: Vacuum chambers can be a bit pricey, but they're a worthwhile investment if you plan on working with resin regularly or on a larger scale. Plus, they're super satisfying to watch in action!
Heat gun/blow-torch
If you are not using silicone moulds then a heat gun or blow-torch can be your bubble-busting buddy. If you are using silicone moulds then remember my motto:
“Always a long-necked lighter, never a torch”
Here's how to put it to work:
After pouring your resin, gently pass the heat gun over the surface, keeping a safe distance to avoid scorching or creating new bubbles.
The heat will cause the bubbles to rise and pop, leaving you with a smooth, bubble-free finish.
Be sure to keep the heat gun moving and avoid holding it in one spot for too long.
Pro Tip: Heat guns come in various temperature ranges, so make sure to use one suitable for resin work. And don't forget to keep a safe distance to avoid any accidental burns or resin mishaps.

Patience
Sometimes, the best solution is simply to let nature take its course. Believe it or not, many bubbles will naturally rise to the surface and pop on their own, given enough time.
Here's how to embrace the art of patience:
After pouring your resin, resist the urge to immediately start popping or removing bubbles.
Allow the resin to sit undisturbed for a period of time, typically around 10-15 minutes.
During this time, many bubbles will naturally rise and pop, leaving you with a smoother surface to work with.
Pro Tip: While patience is a virtue, don't let your resin sit for too long, as it may start to cure before you have a chance to address any remaining bubbles.
A method you should not use
Some of you may have come across the “straw” method. There are many websites and videos suggesting the use of this method. This is where you use a drinking straw to blow on your products. DO NOT DO THIS. This method requires you to not wear a mask and actively breath in resin fumes. Resin fumes are dangerous and can cause serious health issues.
“The main effects of overexposure are irritation of the eyes, nose, throat, and skin, skin allergies, and asthma. The solvent additives can cause other effects such as headaches, dizziness, and confusion. ”

Before I let you go, here's a final pro tip: prevention is always better than cure. Make sure to properly mix and prepare your resin according to the manufacturer's instructions, and consider using a resin specifically designed for bubble resistance.
Now, go and create your resin masterpieces, confident in the knowledge that those pesky bubbles won't stand a chance against your newfound bubble-busting prowess!
