You created a fantastic resin casting only to check on it later to find spider-like veins running throughout. Your resin has cracked! Unfortunately, epoxy resin cracking happens most commonly when resin gets too hot, then cools off quickly.
Why does my resin keep cracking?
The chemical reaction between resin and hardener as epoxy cures will generate heat. The resulting massive build up of heat can cause the cured epoxy to crack because of the temperature differential between the top and bottom of the container. This uncontrolled heat build-up is called uncontrolled exotherm.
Does resin crack easily?
It is water-resistant, not prone to cracking, peeling, or other damage, and it is a highly durable material that will not break easily or shrink once hardened.
Can you fix a broken resin?

Why does my epoxy look like its cracking?
So, what exactly causes epoxy to crack? The most common reason is the epoxy got too hot while curing, causing it to cure faster and unevenly. The changes and differences in tempurature throughout the pour caused expanding and shrinking, which in turn cracked the already cured areas.
What happens if you pour epoxy too thick?
If your epoxy pour is too thick, the reaction can create too much heat, resulting in a product that does not cure properly with cracks or excessive bubbles. The rule of thumb is if you can make an imprint with your fingernail in the epoxy you can pour again and the epoxy will chemically bond to the previous layer.
Why did my resin cure so fast?
Resin kits have a minimum and maximum mixing amount. Too much resin and hardener mixed together produce too much heat too quickly. 2. When using paints and other solvent-based colors in resin, these can sometimes speed up the resin curing reaction and cause the mixture to heat up too quickly.
Can a resin ring get wet?
Wearing any jewelry in the shower, pool, etc, will cause tarnishing to happen more quickly than usual. Basically, don’t submerge in liquids, even if it is just water. And the “extreme heat” is good to avoid but boiling water is actually fine with epoxy resin in my experience.
Is epoxy cancerous?
Tests on laboratory animals showed that older epoxy resins caused skin cancer. It is, most likely, due to epichlorohydrin, which probably causes cancer in humans as well. However, newer epoxy resins contain less epichlorohydrin, so they don’t cause cancer in animals.
Does resin turn yellow?
Epoxy resin turns a yellow hue due to exposure to a myriad of elements. High temperatures, excessive amounts of water, and UV light can all cause the epoxy to change from clear to yellow in tint. Epoxy hardeners can also experience a yellowing discoloration that compounds the epoxy’s off-color issues.
What is the best glue to repair resin figurines?
Plumber’s Goop adhesive works great to repair resin figurines that reside in your garden because it holds well and is weatherproof. Choose an epoxy for indoor resin figurines.

How do you fix acrylic resin?
Fixing cracks in acrylic resin is a little different than attaching parts that have broken off. Handle large cracks by filling them with plumber’s putty. You can use a putty knife to smooth the putty out in the crack or you can wet your finger and smooth it out that way.
Why is my resin not hardening?
If your epoxy resin hasn’t cured properly, this means that the chemical reaction between the resin and hardener was not able to take place. Sticky resin is typically caused by inaccurate measuring or under mixing. Try moving your piece to a warmer spot: if it doesn’t dry, re-pour with a fresh coat of resin.
How do you smooth and resin polish?
Wet sand the resin with 400 grit sandpaper to remove any scratches. Spray some water on your resin piece or dip it in water to get it wet before smoothing it out with the sandpaper. Sand the entire surface of the resin 2-3 times before moving on to the next step.
