Master Using A Heat Gun For Resin With These Tips

how to use a heat gun for epoxy resinIf you HATE bubbles in resin (Let’s get real–who likes bubbles in resin??), then you’re going to love this. I’m showing you how to use a heat gun with resin so it cures crystal-clear.

And if you LOVE bubbles in resin, then you’ll want to keep reading. Because there are ways a heat gun can help you make epoxy art.

And maybe think about getting therapy. Along with those who enjoy sanding resin.

Why use a heat gun for resin?

It’s safer than a propane torch or lighter.

Because the heat gun doesn’t have a flame, it’s harder to set something on fire. This is pretty important if you use solvents like acetone and alcohol in your work. Both of these can make your epoxy catch fire.

⚠️ IMPORTANT: Notice I said harder, not impossible to start a fire.  Have a fire extinguisher handy anytime you’re working with resin.

Heat guns produce heat with very little air ‘force.’

This means you’ll get a lot of hot air without feeling much velocity.

Yeah, I don’t like physics either, so let’s compare this to a hairdryer.

Turn on a hairdryer and put it up to your face. You’ll see your hair flip everywhere. And if you don’t, this movie clip sums it up perfectly.

Do that with a heat gun and your hair won’t move. And that’s what makes it ideal for resin projects. You won’t blow resin all over the place like you would with a hairdryer.

Heat guns can help make cells in resin art.

Cells are the holy grail of resin painting. Heat guns help you make resin cells because they push resin over the surface of your painting.

But before you use a heat gun, there are a few safety precautions you need to know.

The tip of the heat gun gets very hot.

You don’t want to touch the metal mesh end after using it because you can burn yourself.

Use the kickstand on the heat gun.

Because the heat gun end can burn or warp a table or a surface, set it down on your table using the kickstand. You don’t want to scorch your table.

Be mindful of touching the heat gun.

Just because you have gloves on, doesn’t mean the resin stays on the gloves. Wipe your hands before grabbing your heat gun. Resin from your gloves will transfer to the heat gun and gets it sticky. And that sticky resin will be hard to get off later. Go over the surface of your heat gun with an alcohol wipe before putting it away to make sure it’s clean.

So how do you use a heat gun for resin?

Step 1

remove bubbles with a heat gun

Keep your heat gun about 2 inches from the resin surface. Go over your surface in a back-and-forth or circular motion. You should see bubbles pop.

Step 2

For stubborn bubbles, you can get a little closer. Move the heat gun quickly to jiggle the bubbles and get them to pop. This works well when the bubbles are in corners or tight spots.

Step 3

applying heat to epoxy art with a heat gun

If you’re using a heat gun to make resin, use it to push your resin for art. The closer you get the gun to the surface, the more you will move the resin.

What else should you know about how to use a heat gun for resin?

The heat of the heat gun adds to the temperature of the resin.

It’s normal for resin to get hot when mixed. This is important to make sure it cures. But, there is too much of a good thing. A resin that gets too hot will cure too quickly and be unusable.  Keep your heat gun moving, so you don’t apply too much heat to one spot.

A heat gun can damage molds.

Applying too much heat to resin molds can damage them. Your resin can stick to the silicone making your molds unusable.

A heat gun will only remove surface bubbles.

A heat gun is great at getting surface resin bubbles. But, it will not get ones at the bottom of your mold or spread throughout the resin. You’ll have to find another way to get those rotten scoundrels.

Don’t sweat it. I’ve got an attack plan for those too.

  1. I did resin two days ago. Some bubbles started to appear. Can I use a heat gun still to get rid of them?

    1. Hi Amanda, I’m afraid it’s likely that your resin has cured enough that a heat gun won’t work.

    1. You can Rebekah, but it only gets off the surface bubbles. If your bubbles are deep in your cup, the heat gun isn’t going to get those.

  2. My resin has tiny bubbles that didn’t appear until the heat gun did this. Seems the resin blistered from the beat gun, this was the top final coat going on an it clouded up and blisters over the etchings

  3. Can the heat gun be used on resin that’s sitting in a silicone mold? or can it only be used when pouring resin onto a surface?

    Will the heat be able to go through 0.5″ of silicone and pop bubbles without damaging the mold?
    Most of my resin projects I don’t actually see the resin when it’s in the mold.

    1. Hi Max, heat guns only work to remove surface bubbles. I’m afraid it won’t penetrate a silicone mold enough to make an impact on trapped bubbles.

  4. Help!! I followed the instructions EXACTLY LIKE YOU SUGGESTED, however it won’t cure. Can I put heat on it to see if that will get it hardened? I’m not sure what’s up but it’s so disappointing.

    1. Hi Vicki, I’m sorry to hear your resin isn’t curing. I don’t see that you’ve ever bought Resin Obsession resin, so I’m unsure which directions you’re following. Your resin kit should have specific instructions on how to mix the resin and hardener. While the techniques are the same, every resin kit has its own specific instructions.
