How Are Latex Masks Made?

The process of making a latex mask is an artform that has some slight variations based on the mask maker. While the process varies depending on the mask material, like vinyl or silicone, latex masks have remained basically the same since their creation in the 1930s by the legendary company, Don Post Studios. It takes creativity, skill, and patience to make them. Though there are many valid variations in methodology to make latex masks, this is how we at Vampire Faction approach making masks.

1. Sculpting

The first step to create a latex mask is to sculpt a mold out of clay. The sculptor uses various sculpting tools, brushes, and sponges to form the shape of the clay, to carve in detail, and to add texture to the sculpt. We use WED clay, which is named after Walter E. Disney. His team invented this water-based clay to create his animatronics. This clay is great for sculpting because it can easily switch between being hard or soft by simply adding or removing water. By controlling the hardness of the clay, the sculptor can work on different steps of sculpting, from blocking large chunks of clay together to form shapes, to adding fine detail with small sculpting tools. Some other oil-based clays can be more difficult to work with since one must heat it up in order to make the clay more malleable.

The process of sculpting can take a long time depending on the difficulty and the sculptor’s vision. If the sculptor is having difficulty creating a shape he approves of, he stores the sculpt by covering it with a plastic bag and spraying it with water so that the water stays trapped in the plastic bag, preventing the clay from drying out and falling apart.

Once the final sculpt is finished, we spray our sculpt with Krylon to “seal” it. After the Krylon layer finishes drying, we move on to molding the sculpt with plaster.

2. Molding

Since latex is a water-heavy liquid, we have to create a mold that can absorb water as the latex cures into a solid. Thus, plasters from the “Plaster of Paris” family are perfect for this job. There are a wide variety of formulas made with Plaster of Paris, like Hydrocal, but we use the tried and true USG #1 Pottery Plaster. Pottery plaster is more straightforward to work with because it is easier to recognize saturation (the ratio of plaster powder to water) and has a spacious curing time to work with.

We simply fill a bucket with water and sprinkle small amounts of the pottery plaster powder into the water until the small clumps that form at the top of the water no longer sink. This means the mix has the correct saturation. We then mix the water and pottery plaster mixture until the liquid is homogeneous. Next, we brush on and pour the liquid plaster onto the clay mold as an initial detail layer. This is done so that the liquid plaster seeps into every small crevice sculpted into the clay mold and captures the detail of the sculpt. As the plaster begins curing, it will gradually clump up and solidify. This is when we slab on the thicker plaster mix onto the clay mold as subsequent layers. These thicker layers are meant to make the plaster mold stronger once it fully cures.

Mold-making is an artform in and of itself, and the process changes slightly depending on the size of the mold you are making. However, the overall idea remains the same. After our mold is completely dried and hard as a stone, we clean out the mold from any clay that still remains. Yes, during the demolding process your sculpture will die, but it will forever be immortalized in stone (assuming you do it right)! What we have just made is known as our “master mold,” the very first mold ever created directly from the original sculpt. Once the mold is clean of any clay, we move onto casting.

3. Casting

There are two silly issues when working with latex. The first is that as you “pull” a cast from a plaster mold, the casting removes detail from the mold gradually. This is a classic instance of generation loss or degradation, meaning the more copies you pull from a mold, the less detail it will have. To solve this problem, we are going to need to make more molds. The second problem is that if you wanted to make another mold from one of the castings you pulled from the master mold, the new mold’s copies will be physically smaller than the original. If you keep doing this practice over and over again you will end up with a mask so small that it won’t be able to fit over anyone’s head! Therefore, it is really important that you make a “master copy” so you can create good production molds, the expendable molds used for mass production, for decades to come! And it all starts with the first casting.

It should be noted there are about one million and one different variations of “liquid latex.” The difference usually lies with the amount of water and ammonia that a mix will have. Thus, it is crucial that you use “mask-making latex” as it’s specially formulated for the creation of latex masks. The generic liquid latex you can find at Spirit Halloween will not work for creating latex masks, as that is specifically formulated for make-up.

There are two main types of casting you can do with latex: slush casting and dwell casting. Slush casting is when you pour a small amount of latex into the mold and slush it around so that the liquid latex gradually builds up in thickness. This is highly inefficient in our opinion due to inconsistencies in thickness, so we use dwell casting. Dwell casting is when you fill the entire mold with liquid latex, wait for “x” amount of time, pour the remainder back out, wait for the latex to dry, and pull out your copy. The amount of time you let the mold “sit” will determine how thick the casting will be.

Our very first casting out of the master mold will be very thick to ensure longevity, as this casting will be used to produce many other molds. This thick, first casting is known as our “master copy” and will be used as the gold standard for all future molds. To make a new mold from this master copy, simply apply the steps from earlier to the master copy, but instead of cleaning out excess clay, you can just pull out the master copy for more mold-making. Once we make a production mold and make castings from that mold, we are ready to paint.

4. Painting

Painting is certainly the most fun part about making a latex mask because you really see your monster come to life! There is a lot of discourse about what paints people use for their masks. The main challenge in finding a good paint for latex is whether or not it can be flexible and adhere to latex correctly. For instance, you can’t use your run-of-the-mill Hobby Lobby craft acrylic paint for latex since it is not flexible and will crack and peel right off the latex. Therefore, some people use specially-formulated mask-making paints, and some use ink paints. We use a bit of both of these options, but we create our own paint by simply combining liquid mask-making latex and latex indoor house paint (of the color of our choosing) to a 1:1 ratio. This is a cost-effective way to create quality mask paint in large quantities. If the mix is too viscous for your liking, you can always add distilled water to thin it down.

In terms of applying paint, this is where the artist can do whatever they like! A simple brush will work, but some people use air brushes, rub outs, or stipple sponges to apply paint to their creatures. The subject on “How to Paint a Latex Mask” could be its own book in and of itself. However, the most important takeaway is to have fun while you paint and experiment! That is what we do at the Vampire Faction every single day! We play with what looks good and develop processes to create quality while maintaining affordable prices.

In Conclusion

Whether you are making just a single mask for your costume or mass producing masks for people all over the world, the wonderfully artistic process remains the same. We at the Vampire Faction hope you learned a thing or two about latex masks and have a fonder appreciation about this truly unique art form. Despite the hard work and challenges of making a latex mask, we do our best to deliver quality products to make sure everyone has the best Halloween imaginable!
