What I’ve heard (and found with a quick Google search) is: “The problem is known as blocking, and can be caused by many factors such as applying an overly thick layer of paint, not allowing adequate drying between coats, reactions between the primer and the finish coat or the temperature at which the paint was applied... too hot or cold.” It’s like the latex paint never fully dries, hence the stickiness. The permanent solution seems to be sanding the paint off and starting over.

There aren't really any great cures for that. I sometimes buy theatrical clear coat and mix it in my paint or mix with water and do a coat over once the paint dries. You can get different sheens so it doesn't have to be shiny.
