This oil on panel had isolated flaking, and some areas of lost adhesion between the ground and the panel. Some consolidation was necessary of the flaking paint that was not yet lost. The lost areas were built back up to match the impasto strokes and then color corrected.
These tears were cleaned, trimmed, patched, filled, touched up with paint, and varnished to blend in with the painting surface. They are undetectable from the front of the canvas.
If enough time and care or spent the results are satisfying.
In the detail above, the repair is very difficult to spot.
This was a stained, brittle canvas with a large pressure tear.
With a good restoration job, the patch is undetectable from the front.
