Let's talk about bubbles; whether you're using our epoxy resin to coat a table top, artwork, or a tumbler, they are going to happen! After pouring your epoxy, you will start to see air bubbles rise to the surface and form. Don't worry; this is common! Bubbles can even continue to develop for 60 minutes after the curing process has begun. Some of the bubbles rising to the surface will pop on their own, but you will have to get rid of the rest to achieve a glass-like surface.
Here are some of the methods that are used to get rid of bubbles:
Option 1: Popping bubbles with a pin or a toothpick
Bubbles will pop when you use a toothpick or a pin, but we have found this is a very labor-intensive process of eradicating bubbles, especially for larger pieces of artwork. You should only use a pin or toothpick for a very small piece of art or as a last minute touch up.
Option 2: Blowing on bubbles with a straw
Blowing on bubbles with a straw can cause the bubbles to pop, but it's also a slow process. This method might work on small pieces, but it's not efficient for large artwork.
Option 3: Using a hair dryer to pop bubbles
Heat helps to fight against bubbles, but the heat of a hairdryer is just not intense enough to pop bubbles efficiently. The problem with using a hair dryer is that the air blows around dust and hair that you will be using near your wet epoxy. We have found there are better options than using a hair dryer for bubbles in epoxy.
Option 4: A heat gun
A heat gun will get rid of bubbles more efficiently because the heat is much hotter than what you would get from a hairdryer.
But here you're still blowing a lot of air onto your wet resin, which is a chance of blowing dust all over it too.
Option 5: A butane or propane torch
We find that the heat and intensity of a butane or propane torch is the most efficient way to get rid of bubbles in your resin.
You can use a small culinary torch or a bigger propane version for large art pieces or tabletops and countertops.
Pro tip: Never leave a flame unattended and work in a well-ventilated area. Keep the flame far away from flammable substances. Make sure you use a back and forth motion when torching your project and hold your torch far enough away from it, so you don't scorch and burn the resin. Be sure not to keep it in one spot for too long, as over torching can cause dimples, waves, fish eyes, and yellowing, as well as damage your project.
Pro Tip: Because bubbles can continue to develop for 60 minutes after the curing process has begun, be sure to keep checking your project to complete last minute touch-ups.
