Rublev Oil Medium Impasto Putty (8 fl oz / 237ml) is a stiff oil painting medium made from finely ground calcite, barite, and bentonite in bodied linseed oil. Stronger than Rublev’s Impasto Medium or Velázquez Medium, it produces a short, buttery consistency that holds brushstrokes and supports thick impasto applications.

When added to oil paints, Impasto Putty slightly increases transparency without altering color temperature or extending drying times. It allows artists to build impasto layers that retain texture without slumping or leveling, making it ideal for expressive, three-dimensional brushwork.

Safe and archival, Impasto Putty contains no stearates, solvents, resins, or driers, so it can be mixed directly into oil colors without risk of cracking or delamination. Artists can also use it when grinding pigments to create custom oil paints, giving them a stiff, putty-like texture perfect for textured applications.

Packaged in an 8 fl oz jar, Rublev Impasto Putty is a versatile medium for painters seeking bold, textured surfaces with controlled handling. Now available in Australia, it is part of the trusted Rublev Natural Pigments range designed for professional artists.
