Repairing a Cut in a Painted Canvas

Q. I have a large oil painting, 36×48 inches, which has been cut. The cut is clean, only about 1? inches, but is right through the canvas and in roughly the center of the painting. This is one of my best works and I would like to know if there is any way to repair such damage. As I mentioned, I painted it in oil, using Liquin medium, on canvas, and sprayed it with Golden MSA (mineral spirit acrylic) varnish.

A. It seems that an artist’s best work is often involved in some type of accident. While the answer to your concern about a cut in the canvas seems quite simple, it’s not an easy repair for an artist. As an artist, you possess a talent to create a painting. However, the process and skills needed to repair a painting, while appearing to be within the same realm of skill sets, are vastly different. Your work of art requires professional attention by a trained conservator. Conservators study and practice for many years to understand the physical properties of the complex materials which comprise paintings and their support structures.

Repair of your work of art is possible. The goal of this treatment is to secure the support to mend the tear, bring the painting back to the way it was before the accident and, more important, not alter the painting in a visible way or perform a treatment that will introduce secondary problems. Repairing the tear may require a conservator to attach a new canvas to the back of your painting to provide structural support for the damaged canvas and to serve as a stable surface for aligning the torn canvas. Complicated adhesives and procedures are needed to perform this task. A “homemade” repair could buckle the surface of the painting, make the tear stand out or introduce material that could cause long-term damage. A conservator’s treatment may be costly; however, to mitigate costs, you could seek the services of a conservator who employs students in training. You might be able to have your work repaired by a novice conservation student, working under careful supervision. You might also lessen the cost of the treatment by stating that you will repaint the damaged area yourself once the tear is repaired properly.
