Pentart Cracking System is a two component water-based system to produce the effect of cracked surfaces. First apply a thin and even layer of the Cracking Primer and allow to dry. Once dry add the Crackle Paste using a sponge, brush or spatula this can also be applied through stencils. The paste will crack as it dries and the web structure and size of cracks depends on the thickness of the paste applied. For bigger cracks apply a thicker layer and for finer cracks apply a thinner layer. Set includes one 100 ml jar and one 50 ml jar.
