Classic Crackle Varnish is a water based 2 part medium, allowing you to create that classic cracking in vintage and antique cracked surfaces and painted items. Apply component 1 in an even layer and let it dry completely. Then spread component 2. The depth and the network of the cracks depends on the thickness of the layer and on the technique of the application. The layer will dry transparent and waterproof. Highlight the cracks with Antique Paste or Liquid Patina.
