Water-based, two component crackle varnish to create antique, cracked surfaces. 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. Then apply a solvent-based varnish to stop the crackling process. Highlight the cracks with Antique Paste.
