Cobalt Drier is the most recommended additive for accelerating the drying time of a fine art oil painting. It will speed up the drying of both oil paints and painting mediums.
Only small drops of this product are to be mixed into a painting medium to then be added to paint. It should not be mixed directly into the oil color. With this strong Cobalt Drier a very little goes a long way and a bottle will last long for the fine artist in need.
Available in a 2.5oz bottle
