Global Colours Binder Medium and Sealer is a concentrated pure acrylic emulsion which increases gloss and flow effects when added to acrylic paints.  Ideal medium for glazing, sealing, bonding, and collage work for in transparency and flexibility.  Binder Medium is an excellent medium for the preparation of both rigid and flexible supports, creating a surface which is smooth and easy to paint. 

As a sizing coating on canvas, Binder Medium will effectively seal the surface, preventing absorption of paint and moisture into the fabric.  The acidity in oil paint can rot a natural fibre canvas.  Use Binder Medium on raw canvas to prevent oil absorption from oil paints into canvas fibres.  This can be followed by Global Colours Gesso Primer. 

Binder medium can be tinted with Global Colours Acrylics to create brilliant translucent effects.
