Acrylic paint is a young medium. Acrylic paint has been around for just over 50 years. It has quickly become a very popular medium, thanks to the fact that it is safer than oils, dries quickly, and uses water as a solvent. Acrylic paints when dry, can appear similar to oil paints.
All paints are made up of three basic ingredients-pigment, solvent, and binder. Acrylic paint is no exception. Pigment refers to the color and is usually a naturally occurring substance. The liquid substance that thins the paint is solvent. Water is typically used as the solvent for acrylic painting. The material that hold the pigment together and allows it to be spread over the surface is called binder. Acrylic paint has a binder of acrylic polymer emulsion and dries quickly to create a waterproof surface. It can also can be used as a glue or as an image transfer medium. Acrylic paints are produced in a variety of finishes. Gloss finishes are shiny while matte finishes dry to a dull sheen.
Acrylics can be applied with brushes, palette knives, or really anything at all. In my experience, nylon brushes work best with acrylic paint-although any type of brush will work. It is especially important to keep your brushes clean, as acrylic paints will dry quickly and ruin a brush.
Although acrylics can be applied to almost any surface, most artists prefer canvas, watercolor paper, illustration board, gessoed masonite, or other papers. Any surface is fair game, though.
