Until it isn’t that amazing day.
Because sometimes resin sticks to your mold and won’t release.
Which then makes you google, ‘Why is resin sticking to my mold?’
Hi. 👋 I’m Katherine and I’m going to help you get out of this mess.
Here are reasons why resin is sticking to your mold:
Your silicone mold is at the end of its useful life.
Unfortunately, resin molds don’t last forever. They will dry out, get brittle and tear over continual use. It would be great if they lasted indefinitely, but they don’t.
⭐️ BONUS: Here’s what you can do to care for your silicone molds to make them last longer.
You didn’t use a mold release.
Mold release helps resin castings pop out easily and prolongs the life of your mold.
But really, do I need to do that?
⭐️ BONUS: Here are 3 reasons why I always use resin mold release.
Under-mixed resin can stick to the mold.
Be sure to scrape your mixing utensil and sides of your mixing cup several times while mixing. This ensures your resin is thoroughly mixed before pouring into the mold.

You’re using a torch to remove bubbles.
I get it. Fire is mesmorizing. Until your mold gets hurt.
Excessive heat will melt your mold and cause resin sticking in places. Use a heat tool instead.
⭐️ BONUS: Learn how to use a heat gun with resin.
You’re using molds that aren’t meant for resin.
Candy molds? Candle molds? Concrete molds?
Yeah. They might not work for resin. I know because I’ve tried.
⭐️ BONUS: Here’s what happens when you use resin in a soap mold.
Your resin is too hot.
It’s normal for resin to get hot when mixing. But, too much heat can melt the mold, sticking your resin to it.
⭐️ BONUS: Here’s another reason why you don’t want your resin to overheat.
Your silicone mold isn’t fully cured.
If your mold has spots of uncured silicone, the resin will stick in those places and tear when demolding. This most commonly happens with tin cure silicone molds.
⭐️ BONUS: Learn how to use silicone putty to DIY resin molds.
