Ah, bubbles. Every resin artist's worst nightmare. There is nothing like demolding your art just to see those pesky bubbles. How frustrating! As new resin artists, bubbles in your pieces can be extremely discouraging. But don't worry, we are here to give you some tips on getting rid of bubbles in your resin art.
Ready? Set... Let's learn!
There is no way to COMPLETELY get rid of bubbles, however, these tips can help you reduce the amount of bubbles you get in your pieces.
1.) BATHE YOUR RESIN.
Cold resin will result in bubbles. Bathing your resin in warm water will decrease the amount of bubbles. We like to pour our resin and hardeners into small squeeze bottles & label them.
This not only makes it easier to pour your resin but to also bathe them. Don't make your water too hot, it should be warm! Also, don't leave it sitting in the water for more than 2 minutes. Ensure the caps are tightly closed so water does not get into part A or B.
2.) MIX THE RESIN AND HARDENER SLOWLY.
Slow & steady wins the race! Ensure you're mixing your resin and hardener slowly. If you are mixing it fast, you will likely see WAY more bubbles. Mix slowly for the time recommended on the back of your resin bottle (usually 2 - 5 minutes).
3.) USE A UTILITY LIGHTER
Use a utility lighter to quickly go over your resin piece after pouring. Make sure you're not heating it too long or it can cause damage to your mold! It can also make the curing process a lot longer than 24 - 48 hours.
4.) USE A HEAT GUN
Using a heat gun can really help pop the bubbles in big and deep molds. Just like the utility lighter, go quickly over your resin piece after pouring. 2 - 3 seconds is all you need!
5.) USE A TOOTHPICK
Using a heat gun or utility lighter will not get the bubbles out of the corners. :( Use a toothpick to pop those corner bubbles!
6.) USE ALCOHOL SPRAY
This is one of our favorite ways to get rid of bubbles! Put alcohol in a spray bottle and spray the surface of your piece. This will get rid of the bubbles at the top of the mold.
