Silicone Mold Release, 11.5 Wt Oz, Non-Staining, Non-Corrosive, and Fast-Drying, 3.5% Silicone, Easy Part Removal from Molds, Aerosol Spray

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

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.

I think this product is very well designed and works exactly as advertised. Also, I think it's very expensive for what you get so use it sparingly.

Used this on silicone molds that are very intricate and hard to unfold. Made unmolding much easier. Does have an odor and cloud flume but it dissipates quickly.

I am casting pavers for flag stones and have been using motor oil for a release agent but I wanted to try this thinking is was as good and a cleaner way to go. As you can see in the Pic's the oil is better, on the left with oil the paver falls out clean but as you can see the silicon leaves a lot of residue and the paver finish is not good because of the transfer of the cement to the mold, oil is the best I have used

I use this CRC product for my vintage car collection, I spray it on all the parts that may be susceptible to rust or corrosion. It leaves a microscopic silicone coating that drys and is not tacky (like WD-40 or others) and protects parts from corrosion. Also excellent on my motorcycle and bicycle. Try the CRC food grade silicone spray also.

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