Varnishes are final coatings which protect finished pictures from the build up of dirt and grease. Thinly painted acrylic films may be vanished after 24 hours of drying time, but up to a week of drying time should be allowed for heavy or impasto layers before varnishing. In addition, varnishes may be intermixed for a variety of finishes. This is a removable matt varnish for the protection of finished artwork. This product can also be mixed with Galeria Gloss Varnish to vary the final finish.
