Golden OPEN Mediums

OPEN Mediums are used to extend and to modify the viscosity and transparency of OPEN Acrylics while maintaining their maximum working time. OPEN Mediums may be blended with Golden Acrylics, Medium and Gels, with the open time of the resulting mixtures being proportionately reduced.

GOLDEN OPEN Acrylic Gels and OPEN Acrylic Mediums are formulated with 100% acrylic polymer dispersion and have been engineered to have the same optimized working time as OPEN Acrylic Colors, making them ideally suited for use with this line of paints. Like OPEN Acrylics, OPEN Mediums will also stay wet on the palette for extended periods without skinning over.

OPEN Mediums can be used to extend paint, regulate transparency, create glazes, increase gloss, reduce viscosity or improve adhesion and film integrity.

OPEN Mediums are fully compatible and may be blended with most other GOLDEN Acrylics, Mediums and Gels, with the open time of the resulting mixtures being proportionately reduced. 

Thinner: OPEN Thinner will reduce the viscosity while still preserving the optimal working time. Since OPEN Thinner contains no binders, limit additions to a maximum 3:1 ratio of 3 parts OPEN Gel or Medium to 1 part OPEN Thinner to maintain film integrity.  Undiluted thinner can also be used to lift colour, even after OPEN acrylics are dry to the touch. 

Gels: OPEN Acrylic Gel is supplied in the same consistency as OPEN Acrylic Colors out of the tube and is used to extend the paints while maintaining working properties. 

Fluids: OPEN Acrylic Medium is formulated to a lower viscosity than OPEN Acrylic Colors and is used to maintain properties when a more fluid mixture is desired to increase flow.
