How do I use black rubber powder with liquid latex?

If you’d like to extend and thicken your liquid latex and reduce the number of coats needed, begin by applying four coats of plain liquid latex to your model. After this has dried, mix black rubber powder into your liquid latex in a 1:1 ratio. Continue brushing the latex onto you part for 15 coats.
