Transparent Glazes: 7 -10 parts medium to 1-part color.
Translucent Glazes: 4 - 6 parts medium to 1-part color.
The amount of medium added will vary depending upon desired effect and color chosen (colors vary in pigment load and opacity).
Transparent and translucent colors produce the brightest and clearest colored glazes.
Thick transparent glazes can be achieved usinf Gloss Gel Medium or Gloss Heavy Gel Medium, mixing similar to above.
Thinning
Glazes may be thinned up to 25% with water or Flow-AidTM Water (1 part Flow-Aid Flow Enhancer, 20 parts distilled water), without affecting clarity or adhesion.
Increasing Open Time
Working time varies according to temperature, humidity, absorbency of surface and air flow above surface while working.
Seal surface prior to glazing with layer of Liquitex GM&V or Matte Medium. Unsealed gesso is absorbent and can absorb first glaze layer, reducing open time.
Air flowing above surface will make acrylic glazes dry quicker. Close windows and vents if necessary during glazing applications.
Hot, dry temperatures reduce open time; cool, moist, humid temperatures increase open time.
Lightly misting surface during application will increase open time.
Appearance when wet and when dry
Some mediums may appear milky when wet, but will dry clear. This makes those colors appear less intense, lighter and slightly milky while wet. When dry, colors will be more intense and clear. Before applying to surface, paint a test swatch on similar surface.
Matte Glaze Finish
For a matte glaze finish: mix paint with GM&V. When glazing is complete, varnish with a layer of Liquitex Matte Medium (for matte sheen) or Matte Varnish (for satin sheen) on top. Do not use Matte Medium for glazing techniques. Successive layers of Matte Medium will produce clouding of colors.
