How to Cast a Plaster Hand Part 2

 

In this part of the tutorial we cast the plaster into the mold and this makes our copy. We remove it and paint it.

Part 1 of this tutorial is here

 

 

add the plaster

Now we mix up our plaster. We are using Hydrocal. With that we use 1 part water to 2 parts hydrocal. Mix it according to the directions. For this we shake pour it into the water then let it sit for two minutes.

 

swirl it around

Pour a portion of your hydrocal into the mold and swirl the mold around a bit. This is to get it into the various creases and holes inside. It minimizes any air pocket formation.

 

pour the rest of the plaster

Then go ahead and finish pouring the rest of the hydrocal in.

 

Rap to remove air bubbles

Rap on the table sharply many times. This will release any air bubbles in the plaster. You will see bubbles rise up in it.

 

Remove it from container

Once the plaster has set you can remove the whole thing from the container.

 

Cut away the rubber

Using a plastic knife cut away all the rubber from the mold.

 

Continue removing rubber

Continue removing the rubber until it is all gone. It is easy to do. It isn't like real rubber it is more like jello.

 

clean it up

There will be little imperfections in the cast. You can clean these up gently with a variety of tools including x-acto knives, sand paper, and small files.

it looks good

The cast is done and it looks great! Now let's paint it.
