Thursday Quick Tip:
When using Plaster in a ComposiMold mold, be sure to mix the plaster and water at a 3 Part Plaster to 1 Part Water ratio. This may seem too thick to you but we assure you, it will yield successful, strong parts and it won't degrade your mold like an overly wet mixture would.
For this small mold, I used a stir stick to "smear" the plaster and water mixture into the most detailed areas of the mold first. Then I picked up and dropped the mold onto the table a few times to release any air bubbles that might have been trapped in the plaster. Then I "smeared" more plaster into the mold until it filled the rest of the cavity.
I then used the stir stick to gently scrape out any excess plaster while it was still soft. This will save you a lot of time and energy cleaning up edges once the pieces are cured and hardened.
Let the plaster cure in the mold for a few hours, for this sized mold. Don't rush things and pop them right out because that is how you break your castings...
The plaster I used in this project was ComposiMold's own ComposiStone. It is as smooth as plaster, but as strong as cement. Follow this link for ordering information!
