Golden Open Thinner is a water-based additive designed to thin the consistency of Open Acrylics without altering open time, as well as to maintain and adjust the workability of colors on the palette. Open Thinner contains no binders, does not form a film, and should never be used alone.
Add sparingly to acrylic paints, starting at approximately 10 parts paint to 1 part thinner. Maximum addition is 3 parts paint to 1 part thinner.
Open Thinner can also function as a thin-bodied retarder when used with Golden Heavy Body or Fluid Acrylics.
The Open series paints and mediums are best used in thin layers. Applications of more than 1/16 will result in: excessively long drying periods, persistently soft, higher tack feel, and translucent layers that remain cloudy. If it is necessary to apply paint in thick layers, it is recommended to use Golden Heavy Body acrylics.
Available in this series:
Golden Open Gloss Medium: has a lower viscosity than the Open paints.
Golden Open Gloss Gel: has the same viscosity as the Open paints.
