I have a oil painting with a s 1/4″ dimple in the corner of the painting. There is no noticable damage to the canvas, from the back. The paint is slightly damaged but no paint is missing.
I used a little distilled water on the back of the canvas and about 1/2 of the indention came out.
I hate to reline the whole canvas to eliminate the indention.
Any thoughts are appreciated.
I’m a painter, not a conservation professional, but “damaged paint” to me says stop what you are doing and take some high quality photographs to aid in later treatments.
Even though this seems minor and the painting is your own, I am an employee of the University that hosts this forum and am not allowed to offer conservation treatment advice. There are just too many possibilities of making things worse.
