Surface clean, remove varnish, repair damage.
This early 19th century portrait in oil had lost its vibrancy and there were extensive signs of past attempts to retouch and repair some holes and other damage. Removing the varnish revealed the original paint and colour. The retouching was then removed and the holes and other damage repaired and made good. With the painting now restored to its original colour and condition, it was revarnished and, for the final touch, the frame cleaned and regilded, as shown in the video below.
