Liquitex offers a broad range of acrylic mediums to inspire creativity at every stage of the painting process. Liquitex Fluid Mediums perform much in the way that their name implies. They are fluid in nature and reduce viscosity of heavier paints and gels. They tend to self-level and do not retain brushstrokes. Liquitex Fluid Mediums modify acrylic paints in a variety of ways and contain acrylic resins to maintain or enhance adhesion and durability. Can be mixed into any acrylic paint to increase transparency, extend colour, matte sheen, film integrity, ease flow of paint and add flexibility and adhesion to paint film.As Fixative: Use as a matte fixative over artwork to decrease gloss or shine.1 x Liquitex Professional Matte Fluid Medium, 237 ml.
