- 1). Stretch the leg of a nylon stocking over a head form. This form could be anything from a stone statue to a Styrofoam wig form. Special head forms are available from special effects suppliers.
- 2). Trim off the excess nylon from around the neck with a pair of scissors. If there is excess nylon sticking up from the top of the head, cut that off as well.
- 3). Brush a layer of liquid latex over the stocking with a cheap paint brush, saturating the material completely. Use somewhat forceful pressure to force the latex into the stocking. The stocking will give the latex mask extra strength.
- 4). Allow the latex to dry. You can speed this process with a hair dryer.
- 5). Brush a second coat of latex onto the surface. Let it dry, then brush on a third coat. These coats should be thin. Latex dries through air contact; if it is too thick, an outer skin will dry and prevent the latex underneath it from drying.
- 6). Brush more latex onto the mask in small sections. Press cotton batting into the wet sections of latex to begin building up facial features such as cheekbones, snouts and horns.
- 7). Brush more latex over the cotton batting to encapsulate it. If necessary, add more layers of cotton and latex to build up additional thickness.
- 8). Continue adding surface features until you are happy with your mask's shape. Remember to leave empty spaces for the eye holes, nostril holes and mouth hole.
- 9). Allow the latex to fully dry to ensure that the shape is not damaged in the next steps.
Tear the edges off of several paper towels. Use towels without texture stamped onto them.
Brush more latex onto the mask, then lay pieces of paper towel into the latex. This will form a unified skin, smoothing the lumpiness of the cotton layers. The torn edges will blend together better than straight edges.
Brush more latex onto the paper towels to encapsulate them. If desired, scrunch up the towels to create wrinkles, scars and other surface details.
Allow the latex to dry completely.
Paint the mask using paint designed to be used on latex. Begin with a base coat in the monster's main color. Add a darker shadow tone in areas that you want to appear sunken in, such as eye sockets, and a brighter highlight to areas that you want to stand out, such as cheekbones.
Allow the paint to dry.
Cut a slit up the back of the mask with a sharp pair of scissors, then peel the mask off of the form.
Cut the eye, nostril and mouth holes open.
