Schmincke Universal Varnish provides fully cured works in oil, acrylic, gouache, and more with a durable, crystal-clear final layer of protection. This synthetic resin-based formula dries quickly to flexible, highly elastic film that enhances color depth and brilliance while shielding colors from UV rays and resists yellowing and cracking over time. - Schmincke Universal Varnish - Satin Matte, 60 ml, bottleSchmincke Univ Varn, SATIN-MATT 60ML -
