Isolation Coat is a permanent acrylic medium that serves as a barrier between the paint surface and varnish, allowing for improved varnish application and easier varnish removal (Source ID: products-913). It is a ready-to-use sealing coat for acrylic paintings, eliminating the need to mix and measure, and increasing flow and leveling (Source ID: products-913). The Isolation Coat seals the surface absorbency of the paint, providing protection during routine cleaning and dusting, and enabling conservators to remove and replace varnish without damaging the painting (Source ID: products-913, videos-108). It is a significant and permanent addition to a painting, and its use is an aesthetic decision that each artist must make after sufficient testing (Source ID: products-913). Golden Artist Colors offers a range of resources, including videos and technical guides, to support artists in applying Isolation Coat correctly (Source ID: videos-108, products-913).
