Renesans varnish cracked decoupage

Manufacturer: Renesans

The primer paste of milky paste consistency creates a grid of uneven cracks on the surface of acrylic paint.
Directions for use: apply the paste with a dry soft brush to the desired surface. Preferably two coats. Once the last layer applied is only slightly tacky, proceed to apply another color of acrylic paint, preferably a contrasting color to the one under the primer. Stronger cracks can be obtained by changing the direction of the brush strokes, relative to the direction in which the primer was applied. When a new coat of paint is applied, it will crack, revealing the color of the paint underneath. 
Available capacities: 110 ml, 500 ml and 1000 ml.
