Plaster moulds can be used many ways. Often plaster is used to mould a baby's feet or an expectant mother's growing belly as keepsakes. It can also be used on the face. The plaster face mould can be used to make a mask, kept as a keepsake, given as a unique homemade gift or used as a decoration. Making a cast of a face with plaster is an easy and fun craft.
Prep your work area with newspaper. This is a fairly messy craft and you don't want plaster all over when you are done. Prep your work area by laying newspaper on the floor around the area and over anything else that you do not want to get dirty.
Cover your model's face with petroleum jelly. This will keep the plaster from sticking to her face, which would be difficult, and even painful, to remove.
Fill up your bowl with lukewarm water and have your plaster strips ready. These strips can be bought at any craft supply store and are made especially for projects such as this. They are easier to use and less messy than using plaster in its powdered form.
Dip the plaster strips in the lukewarm water and lay them on the model's face. Make sure they are flat with no air bubbles underneath. Remember to leave holes where the model's nostrils are so that she can breathe, and be careful when covering sensitive areas, such as the eyes and lips.
Leave the mask on the model's face for about five minutes or as long as it takes for the plaster to mould to her face. It does not need to dry while it is on her face.
Remove the mould gently and lay it on a piece of newspaper to dry completely. Help your model wipe his face with a wet towel before he opens his eyes. Petroleum jelly may burn his eyes if it gets in them.
Be especially careful to cover areas of your model's face that have hair on them with petroleum jelly. If you do not, the plaster may rip out the hair.
If your model complains of irritation or burning when you place the strips on her face, remove them immediately. She may be having an allergic reaction.
