Review: Fantastic Stuff, Easy to Work With and Great Results - This stuff is fantastic! It's my first time using silicone to make molds, but the Ecoflex-30 was so easy to use, I had no problems with any of the molds. The silicone picked up every detail. I wasn't concerned about bubbles (no vacumm or pressure was used), but to my surprise there were very little if any in most of the molds. Those that did have bubbles, they were tiny and certainly did not affect the quality of the mold at all. Mixing was easy, but be sure to make sure to stir each original container before each use (this is mentioned in the directions and on the containers). I used separate cut solo cups for each part (A + B) to measure, stir again and then mix into one. The working time was easily 20 minutes (prob much longer). I did add some unused left overs into a mold after about 45min-1hr and there was no indication/issue in the final mold. All gell'd together nicely. I'm impatient, so I usually pulled the molds at 4 hours (in a 65F degree room) and they looked great. If I weren't so impatient, I'd probably let them go another couple hours - Some recommend a full 12 hours to be safe. The silicone is very stretchy, but also very strong. I tested one that I stretched to easily 4x its size, and it held up great. I've only had the stuff for about 2 months, but the silicone mixtures are still good (used some today). I'm not sure of the shelf time, but the container does warn that it has a short shelf life. Will definitely order more.
Review: top notch - stuff really is super elastic. very skin like quality

## Questions & Answers

**Q: Does this product require time in a vacuum chamber to use?**
A: No, its quite a thin substance that the air bubbles will rise and escape during the curing process. I purposely cast it a dozen times to see it if I got trapped air bubbles like Dragon Skin, but each one has come out bubble free not matter the thickness of the casting.

**Q: can yoy scuplt a ailicone baby**
A: If you had a mold of the baby you can pour this product into it and you would have a silicone baby.  This is not a good product if your plan is to have a silicone block and then chisel it into a baby.  I would make your baby out of a material that is easier to work with, make a mold, and the fill the mold with this product.

**Q: Has anyone used this as a dip to coat a hard plastic prop. If so how thick of a layer will it produce.**
A: You can brush it on in thin layers, but the cure time for this is four hours. It won't cure immediately and might not cure against certain plastics like polyurethane and epoxy. At best you can probably make a mold of the plastic prop and use this to create a grip if needed. This kit can cast up to 2 inches thick in the right circumstances.

**Q: Would this be a soft replacement for the Clone-a-Willy silicone?  My wife complains that the clone a willy is too hard...is this soft yet sturdy?**
A: Soft and sturdy, yes

### ⭐⭐⭐⭐⭐ top notch
*by 9***N on December 29, 2025*

stuff really is super elastic. very skin like quality

### ⭐⭐⭐⭐⭐ Great stuff for casting molds.
*by I***U on June 5, 2017*

Great end results, very easy to use but rather expensive. I have very few bubbles and the ones that I can see are very small. Can be easily tinted with acrylic paints in very small amounts to resemble flesh or what ever your making. EcoFlex 30 is very stretchy and yet semi dense which is good for doing hands and feet so they hold their cast pose. Working time is very good. I like to mix up my batch by first adding part A, adding some color and then adding part B. Mix thoroughly and let sit a few minutes. When I pour, I like to just allow a little stream to flow into the mold to help release any trapped bubbles and prevent new bubbles created by pouring too fast. With a foot mold, Ill add some EcoFlex to the mold and move it around to coat the inner surface and then fill the mold a little more to ensure I allow any bubbles around the toes to release. When possible, Ill even set the mold with the toes pointing downward to ease filling with out trapped air. Slow and steady gives excellent results. I really wish it was just little cheaper and larger 2X amount was available with out placing 2 separate orders.
