CRC 03300 Silicone Mold Release Spray,16oz Aerosol Can

This is the second time I've bought this. Works so well.

Again I'm using for this my mold casting DIY projects in my studio and OMG it's work perfectly and beyond my expectations.

Worked great in this mortar concrete mix. The slab came out very easily with only tiny imperfections. This was my first time molding anything and using concrete so I was amazed how well it came out.

This product works extremely well. I used it when epoxy bedding an item and had zero sticking issues after applying a coat, letting it dry and then applying a second coat before use. It drys pretty fast so doing two coats is no problem. if you are doing relatively small jobs, one cal lasts a long time.

I’d say if you were molding something, it works great and your piece comes off relatively easy. But if you’re making a two part mold, silicone to silicone, this does not work. My piece ended up getting trapped inside. I had to cut it out carefully so I don’t damaged the piece inside. 4 stars for not making it clear that this does not work for two part silicone molds. Yes temperatures were ideal, and I shook the can vigorously as usual.
