Acrylic Mediums

Mediums are used to create an even wider variety of techniques and effects and to prevent overthinning. By changing consistency and finish acrylics can be safely altered to a very large number of different consistencies, from a thin fluid to a thick gel. Each consistency is available in either matt or gloss.

Additives change the paints working properties, but as they are not made with acrylic binders, must be used in the correct proportions.
