Custom Slushcast Prosthetic/Mask Tutorial

Lifecasting the Face Edit

Materials Needed Edit

Procedure Edit

  1. Clean face.
  2. Rip plaster stuff into little strips.
  3. Put strips in container filled with lukewarm water.
  4. Put on bald cap to protect hair.
  5. Slather, face, jaw, forehead, anywhere your going to put the plaster in vaseline.
  6. Have friend cover face in plaster strips. Go different directions, horizontal, vertical, diagonal.
  7. Use tiny strips to get around nose so you don't have to do the straws in the nose things.
  8. Cover face well. Don't have any gaps or skin showing through in areas.
  9. Sit and wait. Don't move. Don't let friend say funny things that will make you laugh.
  10. After about 20 minutes take off. You can kind of wiggle you face to get out of it.
  11. Fill in any gaps, like around the nose, with more strips so that you have a solid cast.
  12. Let set.
  13. Fill cat box with sand.
  14. Nest face cast into sand. If you need to block off some areas, like if they aren't too deep and you think plaster might spill out, set a piece of cardboard againts it.
  15. Cover inside of face cast, and possibly cardboard, with vaseline.
  16. Mix plaster in a plastic container with a plastic spoon.
  17. This is the type of plaster than comes in a large bucket and is just powder.
  18. Generall it's a two to one ratio of plaster to water.
  19. Sift the plaster into the water, don't dump it all in at once.
  20. Another way to measure is to sift your plaster into the water until the water stops absorbing it.
  21. Stir plaster.
  22. Pour into face cast.
  23. Leave it alone for a long time to let it set.
  24. Free your new postive cast from the negative one.
  25. Wipe it off, if there's any holes you can mix up a little plaster to fill them in.

You now you have a face cast, yay!

The Sculpt Edit

Materials Needed Edit

  • Clay (Visit link for reccomended types)
  • Aluminum foil

Procedure Edit

  1. Get a big piece of foil and cover your new face in it. This makes it so that you can actually get the clay off later, and so that everything won't become a big mess of plaster.
  2. I like to start at the nose and gradually squish the foil down. You don't want any holes or tears in this.
  3. Sculpt what you want your prosthetic to look like on your face with the clay.
  4. Build a clay wall around the prosthetic. Give a little space between the prosthetic sculpture and the wall.

Casting the negative Edit

  1. Cover everything within the wall in vaseline.
  2. Mix enough plaster to fill the inside of the wall.
  3. Pour plaster in.
  4. Once again let it set for a long time.
  5. Remove clay wall.
  6. Take off new negative cast of prosthetic.
  7. Clean the inside of the cast out. That is wipe it down with paper towels.

The Slushcast Edit

Materials Needed Edit

Procedure Edit

  1. Pour latex in, not quite so much as to completely fill up the mold.
  2. Swish it around so that the whole prosthetic-to-be area gets covered.
  3. Keep swishing for a few minutes.
  4. Pour excess latex out into a tupperware container that has a cover.
  5. Let dry a bit, it'll kinda change color when it does this.
  6. (If you have a hair dryer with a cool setting you can use it to help dry the latex quicker.)
  7. Repeat the swishing process.
  8. Let is sit for a minute to let puddles form in the deeper parts.
  9. Pour out puddles into tupperware and cover.
  10. Once again leave it alone for a long time to sit.
  11. When you come back pull out your new prosthetic!
  12. Use scissors to cut away extra bits.


Slushcast Prosthetic

Slushcast prosthetic, after application and makeup

  1. Clean, tone, and moisturize face.
  2. Glue down edges to face. You might want to use eyelash glue instead of spirit gum.
  3. Apply Old-age stipple around the edges. It helps to blend and contour the edges.
  4. Cover the whole thing in Castor sealer.
  5. Next just put your makeup on. Generally you have to put on a lot of base just to make your skin and the prosthetic the same tone.

That's about it. We did this in class so whenever I said long time that was generally inbetween classes or overnight. Mine looked a little more obvious around the edges than I would have liked. But I imagine there's products out there to help with this too. Plus class time is just never long enough for me to do everything I want. I made a cat face prosthetic for Red XIII btw. Oh ya, and if you don't need and exact cast of your face try it on one of those styrofoam wig heads.
