All 3 of these Winsor & Newton Artisan Gloss, Satin & Matt varnishes are water based and do not contain any hazardous solvents. The varnishes provide finished paintings with protection from dirt and grease and when dirty itself, can be removed with Artisan Varnish Remover. (Please remember as with conventional oil paintings Artisan paintings should be allowed to dry completely before varnishing, at least 6-12 months for thin films, longer for impasto paintings.)
All three Artisan varnishes can be removed with the new Artisan Varnish Remover, when the varnish is dirty or damaged.
