How to Make a Plaster Model

by Roberto Cristofoli


Step 1

1 Buy and use cheap paintbrushes in several measures. After each layer, clean the brush with hot water. You'll notice that after a while, you can't use them anymore.

Step 2

2 Buy enough model-plaster (powder).

Step 3

3 Buy fluid latex. This is an expensive bottle!

Step 4

4 Use and old tin for serving some of the latex for each layer.

Step 5

5 Take a nice, flat and clean model. In this example I took a model of the human skin.

Step 6

6 Brush a first thick layer with latex. Let it dry for at least 4-5 hours. Clean your brush in hot water.

Step 7

7 Repeat previous step for 7-8 times. Even cleaning the brushes very good, latex residues between the hairs will turn into rubber. When your mold is ready, take it carefully from the original.

Step 8

8 Make plaster in the right way; not too fluid and without chunks. Use a kitchenmixer if you like.

Step 9

9 Take your new model out of the mold after drying. You better lay it on the table on the backside and just take the rubber mold away. Don't be afraid damaging it; the rubber mold is very flexable.

Step 10

10 First paint the basic color: skincolor. I forgot to mention buying several colors of paint. Acrylic paintings will do fine.

Step 11

11 For the real handycraftmen and women: use fine brushes.

Step 12

12 Choose the same colors as the original, if you like. You can also make a Andy Warhol-like skin....

Step 13

13 When you're satisfied enough, let it dry for at least 6 hours.

Step 14

14 Your last job is varnishing the model and ready is another nice plaster project!

Step 15

15 Once I got enthousiastic about the result, I choose another model. This is an old one of the head.

Step 16

16 Again, a first layer of plaster...

Step 17

17 Let it dry for a long time ...

Step 18

18 After 8 layers,I took the rubber of the original ...

Step 19

19 Fill the mold with nice plaster ...

Step 20

20 Result after drying ...

Step 21

21 Use your imagination for coloring the organs and tissues. You see, I didn't use mine; all the colors are from the original ....

Step 22

22 Nevertheless, I'm satisfied with my new head! Wish you good luck!
