"Make And Cast Your Own Latex Molds"
Page 4 of 7

Author: Tamara_Dozier, Contributing Editor

Here is my original sculpture after I dug it out of the latex mold. May he rest in peace.

Actually, this is kind of creepy looking.
Now it's time to mix up a batch of hydrostone and make my first casting from this mold. Hydrostone is mixed with water in a 1 to 2 ratio, example: 1 cup water to 2 cups hydrostone. This sculpture takes about 1 3/4 cups water and 3 1/2 cups hydrostone.

I first put the water into my mixing bowl, I then sift the hydrostone into the water. I let it set for about 5 minutes to let the powder completely soak.
After it soaks I stir it with an old spoon being careful to not stir in a bunch of bubbles. I stir for about 3 to 4 minutes to make sure I don't have any lumps in the mixture. The consistency of this mixture is about the same consistency of pancake batter.

Pancakes ... yummmmm!
After the hydrostone mixture is completely stirred it's time to start pouring the mold. I only pour it partially full at first. This way I can tip the mold around to get a coating of hydrostone on the inside of the mold. I also start squishing and poking the mold in spots I think might trap air.
Getting a nice coating on the mold's surface.
