Liquitex - Acrylic Fluid Medium - Slow-Dri Blending Medium - 4 oz - Fluid Mediums perform much in the way that their name implies, they are fluid in nature and reduce viscosity of heavier paints and gels, tend to self-level and do not retain brushstrokes. Fluid Mediums modify acrylic paints in a variety of ways and contain acrylic resins to maintain or enhance adhesion and durability.
Liquitex Medium Acrylic Slow-Dri Blending Medium is an essential medium for creating softer edges and modeling forms. This medium is used to extend the "open" time of acrylics by more than 40%, giving you an opportunity to really work the paint to enhance color blending. You can add up to 50% of this medium, as it contains binder to retain the integrity of the paint film, unlike the additive version.
