Specially developed for the protection of acrylic works from environmental pollutants which can cause surface degradation. Sealing the surface with a matt or gloss varnish provides a barrier film which can be cleaned or removed, but leave the paint itself unblemished. This varnish is solvent based and should be touch dry within an hour. However, as drying can depend on environmental conditions it is recommended to leave a full 24 hours for drying.
