  • Translucent when wet, transparent (clear) when dry.  
  • Dries to a non-tacky, hard, flexible surface that is resistant to dirt retention.  
  • Depending upon substrate, allows moisture to pass through (breathable).  
  • Will not crack as surface expands and contracts during temperature and humidity changes.  
  • Applicable for any surface (flexible and inflexible) including canvas, paper, wood, Plexiglas, etc.

As an Extender:

Mix with Liquitex Soft Body Artist Color to extend volume and increase transparency, while maintaining paint viscosity.

As a Ground:

With Powdered Pigments:

  • Use as a binder with powdered pigments to make an inexpensive student grade Soft Body gloss paint.  


  • Gloss Varnish for flexible surfaces is recommended as the best varnish for acrylic paintings.  
  • Apply Gloss Medium and Varnish as a final permanent varnish over dry acrylic paint.  
  • Varnish surface and environment must be clean, dry and dust free.
