Tree wounds do not heal. The process is called compartmentalization. Trees have the ability to somewhat insulate, ie build tissue that will isolate the wound and keep it from the rest of the tree. This is a generalization. BIG wounds such as this, that are close to the main body are a hazard to the longevity of the three. This tree may well survive a long time, but this doesn't do it any good at all.
Aborists encourage removal of hazard trees next to buildings and have the owners replant something that is site specific, more friendly to the infrastructure in the area. Likely, if this is near a building, or sidewalk, or driveway, it has been compromised by root stress anyway. When you see trees uprooted near concrete, it is the invasion of the root structure that failed the tree. Painting this thing or putting tar on it won't do anygood but give you some visual false impression that you are doing good for it.
