WHAT IS A SURFACTANT
Surfactants work by reducing the surface tension of water. If you’ve seen water droplets bead up on a hydrophobic surface, like the hood of a freshly waxed car, you’ve seen surface tension in action by the ‘bubbles’/ beads of water that appear.
To reduce this, you will need to spray your mold with a surfactant, which wets the surface and creates improved contact between the plaster and the surface of the mold, making it bubble free.
To make a surfactant, place ½ Windex and ½ water into a spray bottle. Shake to mix and spray your mold. If there are deep cavities in the mold, turn the mold upside down before pouring in your plaster to drain any excess liquid.
HOW TO KEEP YOUR MOLDS LEVEL FOR CASTING BY USING Jig Feet
Jig Feet are used to keep the mold level so that the plaster will flow evenly.
As shown in this photo, place the Jig Feet equally as possible on the underside of the mold to maintain a level pouring surface into the mold cavity.
You can buy the mold to create Jig Feet from Elite Artistry, LLC under the tab-- Shop Molds. When casting be sure to fill each cavity to the exact same level.
***SOME molds can be easily placed inside of a bowl or cup to stabilizes and keep level. But, for the larger molds Jig Feet are the best method.
