JO SONJA’S GESSO is a free flowing acrylic ground, suitable for surface preparation under acrylics and oils. GESSO is an effective sealer and prevents moisture loss of the paint through absorption. Jo Sonja’s GESSO creates surface “tooth” which is able to sanded between coats for a smooth finish. White GESSO may be applied directly from the jar, or mixed with JO SONJA’S ARTISTS’ COLOURS to create “pastel primers”. Black GESSO may be applied and, when dry, lightly sanded to create “blackboard” paint.
JoSonja Mediums Gesso Sealer Varnish
JO SONJA’S GESSO may be used in conjunction with all JO SONJA’S COLOURS and MEDIUMS. Also may be used as well as, or instead of, All Purpose Sealer. Used on their own, GESSOs will provide surface “tooth” whereas All Purpose Sealer provides a “slick” membrane. Consequently both effectively seal and promote proper adhesion of the paint.
