Ideal for acrylic or oil works, Liquitex Soluvar Varnishes are transparent, mineral spirit-based varnishes that can be removed to clean away surface dirt. Durable and non-yellowing, they dry to a level, flexible, non-tacky finish that improves surface durability, increases brightness and color saturation, and resists discoloration caused by humidity and heat. Designed for interior and exterior use, Soluvar can be applied to rigid or flexible supports. For acrylic paintings, Liquitex Gloss Medium is recommended to be used as an isolation barrier, which acts as permanent protection for the painting prior to the application of Soluvar varnish.
