Rublev Oil Medium Cobalt System Drier (2 fl oz / 59ml) is a concentrated drying additive formulated with cobalt compounds in oil. Used sparingly, this powerful surface drier accelerates the drying and curing of oil paints, oils, and varnishes without changing their color, gloss, or texture.
Cobalt driers act by promoting oxidation of the oil binder, helping paint films set evenly from the surface inward. This makes them especially useful in humid or cool environments where natural drying can be slow.
Suggested Uses:
-
Speed up the drying of oil paints bound with linseed, walnut, or stand oil.
-
Shorten curing times for oil painting mediums and varnishes.
-
Improve drying of oil-based grounds and underlayers.
Directions:
Add only a few drops of Cobalt System Drier to your paint or medium on the palette. Overuse may cause wrinkling, brittleness, or uneven drying. Always test before applying to artwork.
Supplied in a 2 fl oz bottle, Rublev Cobalt System Drier is a reliable solution for artists who want more control over drying times in their oil painting practice. Now available in Australia as part of the Rublev Natural Pigments range.
