Casting with acrylic paint?

[Hecubus114]

I need to cast something - but it will be going on clothing, so needs to be fairly flexible, but also "plasticy" (not latex). I thought about how acrylic paint is if a glob of it dries, and that seems perfect. Is there a method for making a mold of something I sculpted (fairly small and thin) where I can pour acrylic paint in and let it dry? What would the paint not adhere to as a mold?

or any alternatives that will have the same result...?

If you are using a silicone mold, the paint will just bead up and will not lay smooth enough to work There may also be an issue of the paint setting if it is a two part mold. Considering acrylic paint is relatively inexpensive, I would experiment a little. Maybe dust the mold with talc, and then airbrush on succeeding layers of acrylic paint. You will need a significant number of layers though to get something thick enough to be durable. Also look at flexible sealing wax, like this:

You may want a 2 part mold if you will be using this, but it is paintable.

The only reservations I would have against acrylic paints is the shrinkage factor...

Why are you so against latex?

You might want to consider liquid latex body paints, just Google them... Although designed for direct application they should cast fine in thin molds (multiple layers) with minimal shrinkage and they have rapid dry time making layering easy...

Or else casting urethane rubber..
