Art Spectrum Oil Painting Medium #2 is used as the next fattest medium in the sequence of painting by the"fat over lean" rule. It contains more oil and slower drying than Medium #1.

Medium #1 can be fattened by gradually adding Medium #2. Medium #2 may be used as a glazing medium but if very thin veils of colour are required, it is recommended to use Art Spectrum Medium #4.

Art Spectrum Oil Medium range is also available in #3
