How To Use A Torch on Epoxy ResinPosted on 18 May 16:24
Let's do this.
✅ you've carefully measured and mixed equal amounts of resin and hardener
✅ you've poured and spread your resin out to ( or over ) the edges
Now, you'll start to notice some bubble action ...
Bubbles will start rising to the surface, ready to get popped - this is because our chemist included a special de-gassing agent that gently nudges the bubbles to the surface so you can torch them out, before the resin thickens and cures.
First things first ... you need the right tool for the job!
Hands down, the right tool for popping bubbles is a torch.
If you're intimidated by the idea of using a flame torch ... please don't be!
Nothing ( and I mean nothing ) beats the intensity of a flame for getting rid of those bubbles. Trust us - we've tried lots of different methods to pop bubbles - you can read all about them in our blog Why Use A Torch With ArtResin?
For small pieces, we love our handheld butane-fuelled Artist's Studio Torch - in fact, it's very similar to a kitchen torch used for making crème brûlée.
For larger pieces ( generally speaking, anything over 24" x 24" ) our Artist's Propane Torch Head can't be beat! You simply attach the torch head onto a small propane tank, like the blue one pictured below. You can easily find propane tanks like this at the hardware store.
Next, the step that seems intimidating ( but totally isn't ) ... using the torch 😊
Believe me, once you see it in action, you'll never look back ... promise!
There are a couple of important things to keep in mind when torching:
1) Turn on your torch according to the instructions. Hold the torch a few inches above your artwork, just close enough so that the flame lightly kisses the surface of the resin. You should see the bubbles disappear before your eyes, like magic. If you don't see the bubbles popping, move in just a little bit closer.
2) You'll also want to keep your torch moving at all times in a back and forth motion as if you were ironing clothes. Give the entire surface of your artwork a couple of good passes with the torch, until all the bubbles have disappeared.
💡TIP: When it comes to torching, less is more! You don't want to end up overtorching your resin, which is what may happen if you hold your torch too close to the resin surface or in one spot for too long. Overtorching can result in dimples or ripples in your resin surface, yellowing and even burn marks! Read more about overtorching in our blog.
We're so close friends ... so close!
There's just one more thing we need to do: look at your artwork at eye level under a good light source to spot missed bubbles or stray bits of dust or hair. We love keeping toothpicks close by for exactly this purpose!
💡TIP: If you don't have a light source ( like a bright window ) near your work surface, use a flashlight! It works great!!
And there you have it ... a perfect, glass-like, bubble-free finish.
I knew you could do it!
The last step is to cover your work to protect it from bits of dust or hair or even bugs ( eww ) landing in your wet resin.
💡TIP: We love using a large cardboard box with the flaps cut off. A large plastic tote works great too!
Cover the piece with a box to fit your artwork and wait.
In about 24 hours, your piece will be hard to the touch.
After 72 hours, it will be fully cured and ready to display and admire.

Oh, and a couple of important notes ...
💡TIP: Always exercise caution & common sense when working with a naked flame. Turn off your torch when you've finished using it and never, ever leave a flame unattended. Work in a well ventilated area and keep the flame well away from flammable substances.
💡TIP: Running a flame quickly and systematically over the entire resin surface will eliminate trapped bubbles and won't cause a flammability risk, HOWEVER this changes if foreign products have been added to your resin, such as alcohol or alcohol inks. Alcohol is flammable and will compromise the non-flammability of pure ArtResin. ( For this very reason we developed ResinTint, our non-toxic, non-flammable premium colorant for ArtResin. If you're looking for a colorant for your ArtResin and you want to preserve the non-toxic, non-flammable nature of the formula, then ResinTint is the perfect option! )
