I have had a canvas photo print for 7 1/2 years now and it is starting to crack/peel. Is there anything that I can put over it to protect it? I am not sure what the shop did that I got it from. But I would like to protect it from here on out. Thank you!
If it has already started to crack/peel, there is probably nothing that you can do to save it im afraid.
Some shops will spray a lacquer/sealant onto canvas prints - in the short term they look better as they make the colours "pop", however as the canvas stretches with time, the lacquer cant so it cracks. (this also depends on the quality of the original materials)
You could possibly try re-lacquering it.
