Acrylic paint can be used in two different consistencies. Acrylic paint can be used straight from the tube. It can also be diluted to thinner consistency, similar to watercolor. This flexibility makes it a great medium to explore a variety of painting techniques. Thinned acrylic paint can be applied in thin coats as glazes. It can also be applied to a canvas that has been masked to keep portions of the canvas white or an underlying color base.
Arylics also have mediums that can be added to the paint to give it gloss or a different texture. Texture bases can contain paper pulp, sand, glass beads, or other textured material. Acrylic paint is a medium to play with. Have fun trying new things.
