Rublev Oil Medium Impasto Putty (4 fl oz / 118ml) is a stiff oil painting medium made with finely ground calcite, barite, and bentonite in bodied linseed oil. It is firmer than Rublev Impasto Medium or Velázquez Medium, giving oil paints a short, buttery consistency that is ideal for creating thick impasto and textured brushstrokes.

When mixed with oil colors, Impasto Putty slightly increases transparency without changing color temperature or significantly affecting drying time. It holds brushstrokes firmly in place, preventing slumping or excessive leveling, allowing artists to build bold, three-dimensional paint surfaces.

This medium is completely solvent-free and contains no driers, resins, or stearates, making it safe and archival for direct use with oil paints. It can also be used when grinding pigments to prepare custom paints with a stiff, putty-like texture.

Packaged in a convenient 4 fl oz jar, Rublev Impasto Putty is perfect for artists who want to explore expressive impasto techniques with professional-quality, historically informed materials. Now available in Australia as part of the Rublev Natural Pigments range.
