Skullduggery PerfectCast Casting Medium, 2 lbs Container

We are impressed that this is tough enough not to break/crack or crumble at all when you’re trying to get it out of the plastic (for retainer). It’s as hard as concrete once it dries. Makes really good impressions with very few air bubbles once you vibrate it to get them out. Also, if there’s any small bubbles it’s no problem to fill them after the fact. It’s difficult but not impossible to remove material if you need to (since it’s so hard), mostly because scraping it gives me the heebie jeebies (chills, like nails on a chalkboard). But that’s just me.

I have never used any plaster material or molds. I mixed this up per instructions on the bag poured it into my mold (a stone mold for painting mandalas) and I was a little too short so I quickly mixed up a little more and poured it in. I was a bit skeptical that it would turn out at all but, to my surprise it turned out perfect! No air bubbles, very smooth and was ready in about an hour. I would definitely recommend this product.

Very easy to mix and pour.

I really liked this, but my problem is when I mixed it all up, the bag filled a 12oz cup for a mold, and that's with my item to cast in there, and that's it. Feels too expensive for the amount you get. Otherwise its really good, and sturdy.

Waiting for my grands to come over and make a mess lol

I didn't really think that this would work. But it did. It has held up very well for months and is very strong. Laura

This is a good very good product. It was my first time using any type of casting material. It worked the way I was hoping. I used it a little bit differently than most people, though. I didn't pour it in a mold. I brushed it on styrofoam. I made it thicker as a paste so that I could shape it as it was drying and use it as a filler in spots. I then brushed over it again and it dried nicely. I was going to make a mold with silicone and then pour the casting material, but I wasn't able to make a mold because the 'master models' - (ornate decorative cast iron ornaments) were 20 feet up in the air and I didn't have time to apply a bunch of coats and let them dry in between for the mold to set. I was able to measure the broken areas and along with taking a bunch of pictures, I was able to get an approximate scale to shape the styrofoam. My husband is a mason contractor so he will be the one securely fixing them into place and then painting them. As far as the PerfectCast product, it worked great to coat the foam and I was pleased with the quick drying time....

It's okay. There are slight differences between casting material versus casting powder. This is not white for a natural pour or marble pour. I decided to use it for my test products.
