GOLDEN OPEN Thinner is a water-based additive designed to thin the consistency of OPEN Acrylics without altering open time, as well as maintain and adjust the workability of colors on the palette. OPEN Thinner can also function as a thin-bodied retarder when used with GOLDEN Heavy Body or Fluid Acrylics. 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 OPEN Thinner. Maximum addition is 3 parts paint to 1 part Thinner.
OPEN Thinner should not be used in thick applications. Applications of more than 1/16” may result in:
- Excessively long drying periods
- Persistently soft, higher tack feel
- Translucent layers that remain cloudy
