Jo Sonja's Artists' Acrylic Mediums

Crackle Medium: A transparent medium that causes Jo Sonja's Colours to separate into crackled patterns of various sizes. You can use the crackle medium to simulate the effects of aging.

Flow Medium: an acrylic flattening agent used to level out the textural properties of Jo Sonja acrylic paint. Flow Medium is used to thin paints and other mediums. Water may dilute the paint's acrylic binder, reducing its adhesive qualities. When Flow Medium is added in small amounts, it produces a thinner, smoother paint that leaves no brush marks.

Glazing Medium: A transparent acrylic glazing medium you can use alone or with Jo Sonja's Artists or Jo Sonja's Background Colours. Mix with acrylic color to seal as your basecoat or alone on raw wood as a light sealer. A coat of Glazing Medium is recommended before staining for an even application of stain.

Polyurethane Varnish: Provides the toughest finish available with excellent corrosion, chemical, scratch, and wear resistance. Use indoors or outdoors to provide maximum, long-term protection. The varnish dries clear and is non-yellowing. Jo Sonja's Acrylic Polyurethane Varnishes are available in Gloss and Matte.

Retarder Medium: Extends the drying time of Jo Sonja's Colours. It allows an extended working or "open" time for blending.

Opal Dust: Jo Sonja's Opal Dust is a clear gel that contains tiny light-reflecting holographic particles, which create an interplay of colors reminiscent of gems. Opal Dust may be used alone or applied to a dry pre-painted surface. It is suitable for various surfaces, including paper, card, glass, transparency film, plastic, canvas, wood, terra cotta, tin, fabric, silk, or dried flowers. Mix with Jo Sonja's Artists' Colors before applying for a more subtle effect. Drying time depends upon the thickness of the application. Brushstrokes are evident when wet but disappear when fully dry.
