Is it possible to fix wrinkles in a oil canvas painting?

I have recently aquired a beautiful (but very large) oil painting. The upper right hand corner is wrinkled just under the frame. You cannot see the wrinkle by day but at night when the gallery lighting shines down on the canvas it is VERY noticeable. I would love to repair it on my own but do not know how to stretch the canvas. Any help would be greatly appreciated.Is it possible to fix wrinkles in a oil canvas painting?
My wife and I are picture framers. We would take the canvas off of the stretcher and mount it to foamcore using a vacuseal machine WITHOUT heat. The machine removes 28 pounds of pressure out of the machine which sucks the canvas down and the acid free adhesive bonds it down. The wrinkles will be gone. An experienced framer can do that for you.Is it possible to fix wrinkles in a oil canvas painting?
Try spraying the back o the canvas with water, this usually will make a painting tighter. There are also this widgets you can get at art supply store and you can vedge them in the corners of the stretcher bar.


good luck
