The Daler-Rowney Acrylic Medium Soluble Matt Varnish offers a professional-grade, solvent-based protective shield that safeguards finished acrylic paintings from dust, grime, and UV degradation. This non-yellowing, crystal-clear formula dries rapidly within an hour to a completely non-reflective, smooth matt finish that eliminates glare while maintaining true colour values underneath. It forms an entirely reversible barrier, allowing the varnish layer to be safely dissolved and wiped away with mineral spirits or turpentine for future restoration without damaging the paint film.
