There is something about crackled paint that I am attracted to. I wanted to experiment with it on some of my paintings. I used two types of crackle paint in this 24"x 36" acrylic on canvas. On the turquoise door I used a white crackle paste that I mixed with color and then spread on the canvas with a palette knife. The crackle on the large pot is a clear crackle paint that I painted over the color once it was dry. As the crackle dries, it cracks and you can add a layer of paint to land in the cracks. The following is a large painting where I used both techniques.
The crackle below is the crackle I applied after the painted pot was dry.
The paint on the door is the crackle paste. I mixed it with color and spread it on with a palette knife.
