To make a latex mask, the first thing you'll need, obviously, is liquid latex. There are two main places to find liquid latex (in large enough amounts to make a mask): theater/makeup supply stores or eBay. You might find "Mold Builder" latex at a craft store. This is NOT good for masks; apparently there are chemicals that would make it unhealthy as a mask. Make sure the latex you get is specifically for mask making. If you have a good theater/makeup store in your area, you can see what they have, but it would probably be only a small bottle. You can ask the store about ordering more latex in a larger amount. One gallon of latex is a standard size, and would be more than enough for one mask (you could probably make several masks with a gallon). If you're going to be ordering it anyway, you can get it from eBay. It'll run you upwards of $50 for a gallon, or less if you can find an auction. fun_fx
are sellers who currently have latex in stock. Halloween-time is the best time to find latex for sale (for obvious reasons). There are other online stores that sell latex; find a reputable one and make an order (I recently bought some from here
, great price and quick shipping). The main materials (and cost) you'll need are these:
Liquid Latex - $40-50
Air-Dry Clay - $5
Styrofoam Head, Wooden Dowel, PVC Couplers - $14
The air-dry clay would be found at a craft store like Michael's. The brand I usually see is Amaco. Since craft stores usually have a 40% off one item coupon all the time, you can use that and get a good 10 pound block of clay for about $5. There are other options for clay that will be discussed later. You'll want a Styrofoam head to sculpt off of. A makeup supply store should have them, or if there is a Savers store around, they usually have them. Or eBay is a good option too.
Depending on what you already have lying around the house, the above materials may be all that you need to buy. Still, these are some other materials/tools that I used in the course of making my mask:
