earthBorn Wall Glaze is a specially formulated glaze that works really well over clay and emulsion paints. It is designed to give a wipeable surface to the paints, this making them suitable for high-traffic areas. It does change the surface a bit and so either whole walls need to be treated or areas up to a distinctive level (eg dado rail, picture rail). Can be used to 'seal' up clay plasters thus stopping any dusting. Also great for a base for washes / pigments for the more artistic decorators.
