Plaster figurines come in a variety of shapes and sizes, however, they all have one thing in common, they aren't conducive to uniform paint coverage. Because plaster is very absorbent, it tends to soak up paint. This creates the need for many coats and promotes uneven drying that leads to streaks. To generate a uniform, long-lasting finish on your plaster figurines, apply a special type of primer specifically made for plaster surfaces and condition the primer for better absorption, or you may end up having to apply several coats of paint.

Place your plaster figurine on a canvas drop cloth. Clean the figurine with a damp shop rag. Let the plaster dry for at least two hours.
Pour 1 qt. plaster primer into a 1-gallon painter's pot. Add 1 oz. clean tap water. Stir the diluted plaster primer with a wooden stirring stick for three minutes.
Apply a single coat of diluted plaster primer to the figurine with a polyester craft brush. Let the plaster figurine dry for two hours.
Coat the primed figurine with acrylic spray enamel. Hold the spray enamel 8 inches between the plaster figurine and spray tip when coating the figurine. Let it dry for two hours.
