Derivan Cracking Medium lets you produce works that have that weathered and old country farm feel. To obtain a crackled look, there are three steps and three layers involved. The Cracking Medium is sandwiched between the two layers of different coloured Matisse Background Colours.
 
Derivan Cracking Medium has been made to crack the Matisse Background Colours only. Other brands of paint may work with this medium; however, we cannot guarantee performance.
