Remove Bubbles Easily

Jan 19,2022 | PUDUO


You watch the videos of artists who make fantastic products using Puduo Resin, but when you try it, it has bubbles 🙁

Here’s why, and how to fix it:

First, let’s go through the “why”….

When you mix Epoxy Resin, you are mixing 2 chemicals together to create an exothermic reaction. This generates heat. Heat makes the product thin out, which helps it degas. If you pour this product before it has released the bubbles, aka degassed, you run the risk of the bubbles remaining suspended or even worse, attaching to your mold and creating bubbles on your finished surface.

The best way to minimize the risk is to stir slowly. Any bubbles in your product are a result of your pouring and/or your mixing technique. There is no way to mix and get zero bubbles. You will always get bubbles when you mix. There are a few different techniques you can use to help this product release the bubbles before you pour.

And now the “how”….

1.Ensure your room is at a proper working temperature. This product works best in the high 70’s. It doesn’t have to be exact, but the lower the temperature, the thicker the product. If it is too cold, you may run into curing issues.
Some artists will heat the product in a warm water bath prior to mixing. This is a great way to thin out the product. It is not necessary, but it can help.

2.After you mix your product, pour it into another cup. Get as much out of the cup as possible and scrape the mixing stick off into the new cup. Now mix again for about a minute. This ensures there is no unmixed product in the cup or on the stir stick.
Here’s the magic trick. Let it sit for 10-20 minutes. All of the bubbles will either be gone, or sitting on the surface waiting to pop. This product has a 40 minute working time, so there’s no need to rush your project!

3.Any surface bubbles can be popped using a spray bottle with rubbing alcohol. This is the most amazing method of getting bubbles off the surface! You can even take it a step further and spray your mold prior to pouring. This helps with those problem areas on intricate molds.
