With a little isopropyl alcohol and a toothbrush, you can easily remove the release agent.

Selected User Reviews For Smooth-On Universal Mold Release 14 fl. oz.

Always use a brush to apply your makeup
5/5

"Ease-of-Use" is a good example of this. The first mold has a release number of "2831. " UMR is a "Gloss" release, meaning the finished Resin-based product will have a glossy finish. Epoxy leaves a smooth, glossy finish, whereas MANN 200 is a "Flat" release that leaves a flat, matte finish. Your final products will have a drab appearance. When casting a second Silicone mold over the first Silicone mold, UMR should not be used as a Silicone Mold Release because it will prevent the molds from releasing. Always use a brush to apply your makeup. "Ease-of-Use" is a good example of this. Release 2831" on the first mold, then use Mann 200 spray on the second Silicone mold half after it has dried for 20 minutes. Crystal Clear epoxies benefit from UMR the most.

It appears that it is not as "universal" as it appears
3/5

If it weren't for the fact that the title is deceptive, I would give it 5 stars. This product should not be used with silicone molds. This is a silicone-based product. It's a water-based release agent, which means it'll stick to split or multi-layer surfaces. part silicone molds, effectively permanently gluing them together. When working with urethane rubber, this is a great tool to have. Before making a purchase, I recommend going to the manufacturer's website for more details.

Silicone rubber molds should not be used
3/5

I bought it for the following reasons:br>a. For the Smooth-On, it was in the "recommended" section. br>On the OOMOO 30 Silicone Rubber Molding Kit It's for silicone molds, according to the description. br>br>However, it should not be used with silicone rubber molds. Rather than acting as a RELEASE agent, it acts as a GLUE agent. br>br>Amazon should not recommend using any silicone rubber molding compound with this.

This is not as critical to molding and casting as the manufacturer would have you believe
4/5

That being said, it isn't bad. Smooth-smooth-smooth-smooth- smooth- smooth- smooth- smooth- smooth- smooth- smooth- smooth- smooth- smooth According to on's instructional videos, you should use this stuff to make a two-layer cake. part mold, so the two halves of the mold don't stick together, and resin-based items Because the cast does not adhere to the mold pieces, the molds will last longer. A little- It's preferable to do things correctly than to do things incorrectly. I'm guessing I'm wrong. This stuff does not prevent the two halves of a rubber casting mold from sticking together; Not in the least. Before I figured out the trick, I had to hand-carve two rubber bricks open (do not use; On the contact faces, apply Vaseline or something similar. br>br>This stuff DOES slick up the mold pieces so that when you pour in your resin (I do two-part resin) it doesn't stick to the mold. It won't stick to the rubber nearly as well (part squash molds, so I'm rough on my molds). Although there will always be some cling, this helps to reduce it. For those of us who rely on the less-than-perfect, more expensive, weaker, and 'tear-prone' prone' molding rubbers, this greatly extends the life of those rubbers that would otherwise be limited. You may have to slather it on despite being told not to, but it does a good job of "release. " If you're planning on doing a lot of molding, get a couple of cans. It will help you get the most out of your mold's rubber investment.

It's really good! Not only will the overspray free the plastic from your mold, but it will also free you from your feet when you stand up! It's really good!

Excellent work- Spray it in a well-ventilated area
5/5

This is fantastic! I'm not sure why some people say it won't work with silicone molds- Since I've been using this, I've never had a problem with my resin bonding to molds. The only thing you need to remember is to spray it outside!! When sprayed on inside hard floors, it becomes EXTREMELY slick. I couldn't figure out why my family and I kept slipping and falling in the entrance to my art room and the hallway leading to it, but I figured it out: I was spraying molds inside the room, even in small amounts.

In any case, no skull and crossbones could be found on the label or in the literature - lol.
