Tear Repair

The canvas support was damaged structurally with a tear. To repair the damage, "Thread-by-Thread Tear Repair" was the method of treatment. The distortions were removed at the tear site. Individual threads were realigned and bonded together with adhesive. Local application of bridging threads were applied to the reverse of the canvas for additional strength. This technique is far better than the use of patches or other techniques.

Filling and Retouching Losses

The panel painting,Adoration of the Magi, suffered from extensive damage and previous restoration attempts. The image on the left shows the painting during treatment after removal of discoloured overpaint. The painting on the right shows after treatment after extensive retouching. Some reconstruction of missing elements was carried out using tratteggio and pointellism. This was done so that the reconstructed areas would be detectable as non-original elements. All restoration was carried out using reversible media.

Panel Repair

This panel was an interesting and challenging project. The panel was split in two, the break running from top to bottom with extensive paint losses and many paint fragments. The panel had a convex bow. Treatment involved aligning and glueing the panel and, where possible, reattaching numerous paint fragments. The remaining losses were filled and retouched and a varnish applied locally.

What's involved in

Painting Conservation Treatments

Don has treated traditional and contemporary paintings and a variety of media types including oil, acrylic, egg tempera and encaustic. 

The objective is to preserve and stabilize the painting while respecting the original materials and the artist's intent. It is important that materials used in the repair are stable and reversible. In this way the repair can be removed without damage to the original. 

Initial Examination

CAC begins with a thorough examination, testing and assessment to determine the condition of your painting and plan the best treatment and materials. This includes detailed photographs that may include macro and ultraviolet fluorescence photography. In addition, spot and chemical testing may be carried out with the owner's permission.

Condition Report and Treatment Proposal

After this initial examination, you are presented with a Condition Report, 
Treatment Proposal
and Estimate or Quote.
