Low viscosity products made from hard acrylic emulsion. Can be used as an over-varnish for Atelier Interactive and other traditional acrylic paints. To use as a varnish over an Interactive painting seal with 2 coats of Fast Medium/Fixer before varnishing. They are non-removable, however they can be over painted. The acrylic varnish may be mixed with acrylics as a low viscosity medium to change the sheen levels or to dilute for glazing. Atelier Interactive will dry fast and waterproof if used in this way.
