Varnish

Description

• Availability: Highly stocked in liquid bottles and aerosol spray cans.
• Archival Protocol: Standard hardware varnishes become yellow and brittle, permanently locking onto the canvas or wood.
• Core Products: Conservation-grade, non-yellowing varnishes (often formulated from Paraloid B-72 or Regalrez). These are designed to act as a “sacrificial layer” that protects the artwork but can be safely stripped off later using mild solvents without harming the underlying original layers.
