CASE STORY

THE RESTORATION OF THE 18TH CENT.
PLAFOND OIL PAINTING ON CANVAS FROM CLAUSHOLM CASTLE


Resume: The painting is located on the ceiling of the castle's sleeping chamber no.31. The size is approx. 5.5 X 7.5 m. The canvas support consists of six separate pieces. They have been mounted without frame directly to the wooden ceiling by means of nails (approx. 600). From the floor level the painting was perceived to be in one piece, as the joints between the 6 separate pieces were filled and overpainted. The painting has suffered after a serious roof damage where tar, gravel and water seeped through openings between the ceiling slats and collected on its backside. A serious part of the work involved the separation of the painting from the ceiling. It was necessary to sew together the six separate canvas pieces with double stitches (approx. 20 meters) in order to suspend the painting on its new frame in one piece. As a part of conservation and restoration work, a low-pressure suction table was constructed on site and a wooden key-out frame was specially designed to remount the painting. The total weight of the painting with the frame is approx 400 kg. Eight air channels were built under the roof space over the painting in order to provide proper ventilation.
