A medium to make cracked surfaces for acrylic painting applications. Just pour and spread to achieve hairline or thick cracks. Crackle Ground is easy to apply and manipulate. Its thin consistency makes it flow on the surface by tilting or by spreading lightly with a palette knife. The direction and firmness of spreading the medium will effect the pattern of the cracked formations. NOTE* Heavy pressure will prohibit crack formation. Brushes not not recommended. Pouring and tilting or light pressure with a spreading tool will obtain best results. Appropriate surfaces: Primed surfaces for acrylic applications with a slight tooth or matte finish will result in the best adhesion.
