Blackboard varnish. The blackboard varnish from KREUL turns every free surface into a board that can be written and scribbled on with chalk. Simply paint the flat surface with your favourite color shade from the KREUL Acrylic paints and then cover with the KREUL Blackboard varnish, wait patiently for 24 hours and then paint with the KREUL Chalky Marker or blackboard chalk.
