Tips To Remove Epoxy Resin Air Bubbles After Curing

Hey there, Epoxy Enthusiasts! 👋 Got a case of the pesky bubbles in your resin masterpiece after it cured? Fear not, for we've got some wizard-level tricks up our sleeve for removing air bubbles in epoxy resin. Let's dive in!

First off, remember, bubbles are like uninvited party guests – they just show up! But here's the cool part: during the curing process, these little air intruders naturally make an exit. It's like they realize they weren't on the guest list and decide to leave. 

Now, if some bubbles missed the memo and decided to stick around, don't sweat it! Here's a nifty trick: grab your acetylene torch (yes, it's time to play with a bit of fire 🔥, safely of course!) and gently heat the surface. This little heat wave will coax those bubbles to rise and pop – like magic!

But wait, there's more! 🧐 If you find some stubborn bubbles after curing, here's a secret technique you can use. 

  1. Sand the bubbles away using 222 - 230 fine sand grit paper. (Think of it as giving your piece a mini spa treatment.)
  2. Wipe it down with acetone or denatured alcohol. 
  3. Use a set of metal picks for a clean sweep. (It's like dental care, but for resin!)
  4. Squeeze a little water into the hole, then dry it out. This is like rinsing after brushing.
  5. And finally, use the pick tool again to make sure everything is neat and tidy.

Voila! You've now got a bubble-free, smooth as silk epoxy creation that's ready to wow the world. 🌍✨
