To make homemade latex for special effects makeup, you need 1 cup of cold water and 1/4 cup of tapioca flour. Additionally, 1 pack of plain gelatin and 1 tablespoon of solid coconut oil are required.
Mix the tapioca flour into a sauce pan with cold water, and combine the gelatin and coconut oil. Stir the mixture until the flour is completely dissolved. To create a skin-toned complexion, add liquid foundation makeup into the mix. Stir continuously over medium heat until the mixture transforms into a pudding-like consistency. Stir the compound for an additional minute and remove it from the heat source; let the "latex" cool.
Generally, a batch of homemade latex takes about five minutes to make and about 15 minutes to cool down. After 30 to 40 minutes, place the latex in a decorating funnel or sandwich bag for textured skin, or use a hot knife as a carving or smoothing tool after the latex congeals.
To apply the latex, spoon it onto some plastic film, and let it sit for 30 minutes; apply it to your skin. If you are applying congealed latex, use left-over latex as an adhesive by warming it up in the microwave and rubbing it on your skin like glue. Then apply the latex to the adhesive.
